The invention relates to hydraulic construction and can be used to protect riparian areas, roads, and other objects from landslides and collapses ground arrays.

There is a method of constructing a retaining wall of gabions [1], including the manufacture and laying of gabions in landings along the river. Gabions are placed in the lattice reinforcing cages that are made in advance according to the size of the partition coefficient. The disadvantage of this technical solution is the design complexity and the need of a large number of stone material.

Relative to the closest technical solution is the method of construction landslide structures [2], which includes a base plate on stilts, shore flexible shell of the soil reinforcing elements and drainage wells. The main disadvantages of this method are: the design complexity, low efficiency and high complexity of construction of the structure.

The purpose of the invention is to reduce the complexity of the construction and increase the efficiency.

This goal is achieved by the fact that the method of construction landslide protection works, including laying reinforced soil fastening on the slope, beginning at the base of the slope arrange the preparation of flexible mattresses, made of square is the shaft ranks lung fashin, placed normal to the line of inclination of the slope, then top them perform the fastening of gabion mattresses with drainage device, consisting of lung fashin and perforated pipes laid in alternating rows and wrapped in gabion mesh, flexible mattresses at the base and gabion mattresses on top of them connecting galvanized metal wire with a diameter of 2.5-3 mm, and along the soles Abrosimova slope arrange drainage prism of riprap. Higher slope of the mount of flexible and gabion mattresses suit embedded in obrushenii escarpment additional fastening with a small bias of similar gabion mattresses with drainage device, with gabion mattresses slope and additional fasteners firmly tied up with the reinforcing wire and the end attached to concrete anchors arranged at a certain distance from each other in a stable ground for obrousenim array of the slope.

Figure 1. shows a cross section of landslide structures combined structure along the line of a possible collapse. Figure 2 - the same plan. Figure 3 - gabion mattress. Figure 4 shows a light fashina of dry reeds.

Landslide structure consists of a soil body 1, a flexible mattress 2 from the lungs fashin, gabion mattresses 3 and 4, be the traditional anchoring devices 5, stone prism 6.

The method of construction landslide structures combined structure is implemented and works as follows.

First, for the production of light fashin and gabion mattresses prepare in advance the necessary amount of dry reeds, and macro-grained rock material for the device stone prism 6. Then cut and prepare the gabion mesh and perforated plastic pipes (diameter of 40-50 mm) in size gabion mattresses (gabion mattresses can have the following dimensions: 30×20×120 cm 35×25×150 cm, 40×30×200 cm and others). Next, make the required amount of light fashin and gabion mattresses 3 and 4. Then plan to strengthen the slope and make a stone prism of his soles. Along the slope from the stone prism to the top of a slope with dense rows, stack light Pasini and bind them together with galvanized wire (with a diameter of 2.2-3 mm), thus made flexible and stack the 2 mattresses on the slope. Above them, also along the entire length of the slope mount gabion mattresses 3, connecting them with each other and with flexible mattresses 2 using galvanized wire. Above fortified escarpment plan area with slope and deepening to indigenous soil (outside the line of a possible collapse of the soil mass). At the end of the platform in the native soil through opredeleniya (10-20 m) arrange concrete anchors 5 with the armature mounts. Then the entire length of the pad mount gabion mattresses 4, starting from the top of the slope mount, securely connecting them to each other and gabion mattresses slope fastening. This gabion mattresses 3 slope fastening and gabion mattresses 4 top site bandaged tightly reinforcing wire (Al ø 12-14 mm) and attach to the anchors 5 places of their location.

Landslide construction of a combined structure, constructed by the proposed method works as follows. Due to the fact that gabion mattresses are made of flexible structures with drainage device, is provided to intercept and safe discharge of seepage flow from ground array, including surface runoff, stecaomega from the slope. In the line of a possible collapse provided the necessary traction and friction, securely retaining the ground mass from possible falling or collapse. In addition, provided in the construction of additional anchoring increase the stability of the entire array, resulting shear strain rassridotachivaytes and extinguished due to the flexibility and strength of gabion mattresses 3 and 4. Here gabion mattresses 3 and 4 play the role of protective fixtures, and drainage devices that work together to hold the soil mass and safe is Toda surface and ground water flows.

Thus, landslide building, erected by the proposed method provides reliable protection of various objects located under the slopes and slopes where possible landslides and collapse of the soil massif. The most effective can be used this way, when the height of the potential collapse of the soil mass does not exceed 10-12 m At this relatively low altitude you will be able to provide reliable and collaboration of all fixtures and drainage devices. However, this construction does not introduce interference in the circulation of substances and energy, helps the development of nature. Through the gabion fastening freely grow green plants and light fachini in these mounts, holding moisture, create favorable conditions for germination of grasses and shrubs.

The method of construction landslide structures designed for engineering protection of national economic interest from possible landslides and falling slope of the soil massif of the mountain and foothill areas.
