The invention relates to the field of hydraulic engineering and land reclamation construction and is designed for drainage, engineering preparation of the built-up areas and their engineering protection from flooding, mainly in the areas of distribution of permafrost, and can also be used for drainage of any land, including agricultural land in permafrost.

The flooding of developed areas is a pressing problem for many Northern objects of economic activity. Harsh climatic conditions repeatedly complicate the tasks associated with the development of effective interventions for engineering protection of developed areas. Water saturation of the soil adversely affects their properties, which complicates the construction and operation of the facilities and ultimately leads to a significant increase in operating costs. The present invention is based on the concept of maintaining water balance in the area and represents a comprehensive solution to the problem of flooding by creating a multi-level system engineering protection, mainly in areas of permafrost, perform the function of local aquitard in relation to groundwater upper aquifer layers.

In the prior art Izv the walls the way of thermal land reclamation in the permafrost zone, including the thawing of permafrost, and for agricultural land use in the permafrost zone on rough terrain across a slope occiput layer of drainage material, and higher on the slope beside him perform space, recessed below the surface on the value of a vegetative layer (USSR author's certificate No. 1148936, IPC E 02 In 11/00, published 07.04.85).

Also there is a method of drainage of the land in the zone of permafrost, including drainage in open drainage channels for surface water and groundwater in permafrost the aquitard, which gives the slope toward the drainage channels, and to accelerate drying of the soil produced by continuous milling with simultaneous stirring and aeration of crushed soil (USSR author's certificate No. 1467136, IPC E 02 In 11/00, published 23.03.89).

The disadvantages of the above methods of drying are large volumes of dredging, moving and processing of soil, and in the absence of measures to divert surface water and groundwater, coming from the surrounding areas.

The closest analogue of the present invention to the technical nature and number of similar features is the way complex multi-tiered engineering protection master site a confirmation from the building, including the creation of alsaplayback embankment on the square of the developed territory and organizing activities for the diversion of surface water with the said embankment, the layout of the surface which is produced with gradients, providing a flow to a device for receiving and diversion of surface water, and from adjacent areas and produced during and/or after the creation of the mound measures drainage of ground water from adjacent areas, and removal of ground water from the body of the mound (USSR author's certificate No. 1583535, IPC E 02 In 11/00, published 07.08.90).

In the zone of permafrost disadvantages of this known process are considerable complexity and intensity of work on the laying of a closed drainage system with devices for receiving and diversion of surface and ground water from adjacent areas, and lower during the first few seasons of efficiency created by this method of drainage system due to clogging and the formation of ice jams, which do not have time to thaw during the short summer season.

The present invention is to simplify and reduce the complexity of the work on the development of integrated multi-level engineering protection master site from flooding, including the Isla and in the zone of permafrost, and provision in these conditions, a stable performance of the developed system.

The solution of this problem is achieved in that in the method of complex multi-level engineering protection master site from flooding, including the creation of alsaplayback embankment on the square of the developed territory and organizing activities for the diversion of surface water with the said embankment, the layout of the surface which is produced with gradients, providing a flow to a device for receiving and diversion of surface water, and from adjacent areas and produced during and/or after the creation of the mound measures drainage of ground water from adjacent areas, and removal of ground water from the body of the mound, according to the invention as a device for receiving and diversion of surface water square master of public use of the road system vnutriploschadnykh drainage ditches, and beyond the square of the developed territory system whiplashing drainage ditches that carry out on the perimeter alsaplayback embankments with slopes, reinforced side of the mound, with alsaplayback embankment pave the road with a road surface, the surface of which is deepened relative to the surface of the embankment with a slope to the side and the car roads, and perform with longitudinal and transverse gradients, provides runoff on the road surface waters into the system vnutriploschadnykh drainage ditches, which surface water is directed to a system whiplashing drainage ditches, and surface water runoff from the surface of the mound, located on its periphery away from the roads, and natural surface adjacent to the embankment of the territories referred to whiplashing drainage ditches by giving these surfaces slope towards whiplashing drainage ditches, and at last all entering divert water to wastewater treatment plants or in natural temporary or permanent watercourses, in addition to removal of ground water from the body of the mound in the it stack drainage layer with drainage latest collect water in the system whiplashing drainage ditches, which are also used for extraction of ground water from adjacent developed areas.

In special cases the method is based on a comprehensive multi-level engineering protection master the area from flooding:

- drainage layer is carried out using materials that are reinforcing for the layer of bulk soil, which creates abseplyalamma mound;

- in Rheem layer alsaplayback embankment perform drainage funnel, which from the surface of the mound brought to the drainage layer and fill macro-grained rock material;

- at the location of the developed territory in the zone of distribution of permafrost bedrock beneath the drainage layer lay insulation screen;

before alsaplayback in bulk, along its perimeter, or individual sections of the latter creates a cutoff barrier to the movement of ground water from adjacent areas;

in Northern regions as grout used ledogorov the veil, which is created by using the vertical cooling surface and insulation screens.

The invention is illustrated by drawings, where figure 1 shows created by the proposed method, the system of complex multi-level engineering protection master site from flooding, the plan; figure 2 - is the same, the section a-a in figure 1.

The method of complex multi-level engineering protection master the area from flooding is as follows.

On the square of the developed territory create abseplyalamma mound 1 and the activities of the diversion of surface water from the embankment 1, the layout of the surface which is produced with gradients, providing a flow devices for the reception and removal of the surface of the waters, includes, and from adjacent areas 2 and produced during and/or after the creation of the mound 1 measures the drainage of ground water from adjacent areas 2, and removal of ground water from the body of the mound 1. As devices for receiving and diversion of surface water on the area of master of public use roads 3 and system vnutriploschadnykh drainage ditches 4, and beyond the square of the developed territory system whiplashing drainage ditches 5, which perform on the perimeter alsaplayback embankment 1 slope, reinforced side of the mound 1. At alsaplayback embankment 1 pave roads 3 and the road surface, the surface of which is deepened relative to the surface of the mound 1, with biases towards roads 3, and perform with longitudinal and transverse gradients, provides runoff on the road surface 3 water system vnutriploschadnykh drainage ditches 4, which surface water is directed to a system whiplashing drainage ditches 5. The surface water runoff from the surface 6 of the mound 1, arranged along its periphery at a distance from highways 3, and with natural surface adjacent to the embankment 1 2 territories referred to whiplashing drainage ditches 5 by giving nathanielbagshot gradients in the direction whiplashing drainage ditches 5. At last all entering divert water to wastewater treatment plants or in natural temporary or permanent watercourses (not shown). To remove groundwater from the body of the mound 1 in it stack drainage layer 7 with the possibility of draining the last of the collected water in the system whiplashing drainage ditches 5, which is also used for extraction of ground water from adjacent developed areas 2. For drainage layer 7 of the collected water in the system whiplashing drainage ditches 5 it is performed with inclines towards the latter and to the outputs of the end parts of the drainage layer 7 above the fastening of the slope of the corresponding vneploschadnoj drainage ditch 5 from the side of the mound 1.

Drainage layer 7 can be made using materials that are reinforcing for the layer of bulk soil, which creates abseplyalamma mound 1. As such reinforcing bulk soil materials can be applied to materials such as extruded geoloc.

In the upper layer alsaplayback embankment 1 can be made of the drainage funnel 8, which from the surface of the mound brought to the drainage layer 7 and macro-grained rock fill material.

When the location of the developed territory in the zone of distribution of permafrost bedrock 9 under the drainage layer is 5 lay insulation screen 10.

Before alsaplayback bulk 1, along its perimeter, or individual sections of the latter creates a cutoff barrier 11 in the path of movement of ground water from adjacent areas 2.

In the Northern regions as grout 11 use ledogorov the veil, which is created by using the vertical cooling units 12 and the surface of the insulating screens 13.

In addition, the drawings are additionally indicated:

14 - sole layer of seasonal freezing and thawing;

15 - roof thickness of permafrost rocks 9.

As a result of implementation of the method described above during operation of the facilities located on the reclaimed site, after completion of the drainage of surface waters will be organized system protect the area from flooding, with four levels (see figure 1 and 2). On the first level there is a concentration of surface runoff within the greater part of the territory, not having a solid coating. In this case, the moisture that leaked in bulk soils, is conducted outside of the mound 1 at drain layer 7. The slope of the mound 1 is set so that the discharge was carried out on the carriageway of highways 3, which form the catchment of the second level, because the level of the surface of roads 3 is not the reality below the surface elevations of the adjacent part of the mound 1. The movement of water on the road 3 is provided by their gradients in the longitudinal and transverse directions, and the discharge of water from the surface of roads 3 is carried out in the system vnutriploschadnykh drainage ditches 4, which form the third level of the catchment. Using vnutriploschadnykh drainage ditches 4 water is diverted outside of the mound 1 in the system whiplashing drainage ditches 5, located on the perimeter of the mound 1 and forming the fourth level of the catchment. Among other things, nepodemnye drainage ditch 5 take surface water accumulating on the adjacent territory 2 the embankment slopes 1. Water discharge from whiplashing drainage ditches 5 is in the direction of natural drains (strip drain, temporary and small streams. Thus, the stored water balance of the area.

Strengthening channels vnutriploschadnykh and whiplashing drainage ditches 4 and 5 by using such material, as the volume of the geogrid. The use of this material allows you to create trenches 4 and 5 are different in the form of a transverse profile with variable size along the length of the trench 4 or 5, which is quite difficult to perform when using rigid structural elements. In the case of deformation of channels such vnutriploschadnykh and whiplashing drainage ditches 4 and 5 is practically not disturbed and is functioning and is not happening erosion erosion of bulk soil along the sides of drainage ditches 4 and 5. Use soft materials for whiplashing drainage ditches 5 allows you to minimize the impact on the natural soils in the works on laying the beds of the trenches 5.

In cases where there is a danger of stagnant surface waters within the mound 1, in the bulk soil to the depth of the drainage layer 7 are arranged drainage funnel 8 filled macro-grained rock material.

Receipts from outside the limits of embankment 1 Admiralty water prevents the creation along the embankment 1, where appropriate, impervious ledogorov curtains 11. Ledogorov veils 11 are on the path of groundwater seepage through the soil freezing with the use of special cooling equipment 12 - vertical vapor-liquid stabilizers plastically soils seasonal and year-round.

This invention provides:

- the possibility of organizing an effective drainage system and its functioning in the early stages of construction;

- implementation during the entire period of operation of comprehensive protection of the bulk layer from the water saturation water with the surface of the mound, and surface and ground water from adjacent areas;

- preservation of natural water ball the sa area and normal environmental conditions.
