The invention relates to the construction, namely the organization of drainage of basements.

Known drainage system sports grounds (patent No. 2344222 EN, 26.10.2007), including different deeps trunk (loop collective) drainage drainage channels and compacted sub-soil drainage layer the drainage system, filled drainage and filter materials. What's new is that in the trunk and drainage drainage channels playgrounds laid wrapped in geotextile, respectively trunk and drainage corrugated drainage pipe. All graded and re-compacted surface of crushed granite playgrounds covered with a layer of geotextile. The entire surface of the specified geotextile filled with compacted, graded and re-compacted granite screenings, the surface of which is covered with a second layer of geotextile on the surface of which is laid artificial turf sports fields.

A device for the collection and disposal of drainage water (patent No. 2327006 EN, 13.06.2006), which contains a drainage pipe connected to the drainage wells, which in turn is connected with a well storm sewer is installed in the vertical pipe drainage pipe with non-return valve, vypolnen the nd with the ability to create a vacuum at the end of it the drainage water. Drainage wells is airtight. Directly connected to the drainage pipe from the well of stormwater drainage well is equipped with a hydraulic valve and is installed below each drainage well connected to the drain pipe so that the water level in the hydraulic gate is always below the level of the bottom wall of the respective drainage pipes.

A known method of laying drainage for agricultural land reclamation (A.S. No. 1701815 SU, 13.12.1989), including meats mole drainage on a continuous track on the background laid subsurface drains, arranged parallel to one another, characterized in that, with the aim of increasing productivity and efficiency of drainage, before cutting mole drainage produce the marking area by loosening the soil along the closed drains and cuts mole drains perform at different depths and with a bias towards the closed drains, with the first mole drains are laid on the diagonal of each plot, and each subsequent mole drains arrange at an angle to the previous one, moreover, the gasket deep mole drains alternated with a strip of small mole drains.

Also known for its improved version (A.S. 990951), in which the middle of the troughs located on adjacent drains, offset from each other by half the distance between the wells, the location is defined in a checkerboard pattern.

There is a method of construction of drainage systems (A.S. 987020 SU, 03.06.1981)including laying of drains and loosening the top layer of soil, characterized in that to reduce construction costs and increase productivity, the top layer of soil is loosened with variable depth, decreasing to the middle between drains.

Known way to combat water erosion (A.S. 1311634), according to which, starting from the dividing line to the contour of the terrain cut hollows series, which are parallel to the drainage grooves and between the recesses. Distance between the lateral grooves is determined by the formula: B=t*Kf(a+2hf)/(Qsh*Kst-QAK), where t is the time of snowmelt, h; Kfthe filtration coefficient of thawed soil-forming rocks, m/h; a is the width of the drainage holes, m; Kst- coefficient of runoff on the slope; Qsh- water storage in the snow at the beginning of snowmelt, m; QAK- the amount of accumulated moisture, M.

The closest analogue is the drainage system (A.S. No. 812879), comprising a closed drainage network connected with wells filled with filter material located at the bottom of the hollow in which to improve drainage, reduce workload and simplify, save plodorodie the soil, hollows made in the form of mutually intersecting depressions with a dome-shaped elevations between them, and the wells are located at the intersection of these hollows.

The aim of the invention is to improve the efficiency of regulation of the water level in the basements of houses, strengthening their foundations of various configurations.

The goal is achieved by creating a depression zone in the soil on the area of the basement, which is the development of a ground, a system of drainage channels within the area bounded by the Foundation of the house. In the channel stack filter material, or a perforated pipe with a filter element. Also developed the soil under the shaft, which is mounted prefabricated filter well for accumulation of ground and emergency water. Channels unite among themselves. In the assembled system allows you to take emergency ground water with a low flow rate. When accumulated in the system emergency groundwater correspond to the norms and standards for wastewater and can be directed into the sewer system.

If the configuration of the basement or design features, such as the presence of walls and/or screed, not allow mounting of drainage channels, apply vertical drainage. For this drill shaft, which amount is inaut depressional areas are divided into areas and create a single drawdown zone. If necessary, under the coupler shafts are interconnected by channels of small diameter. These mines also fall asleep filter material, or insert them in a perforated pipe with a filter element.

Removal of accumulated and filtered water are performed with use of pump power from 200 W to 400 W, which supply the machine, including the pump only when the rise of water in the well to a certain level and disables it when the water level dropped Yes a specified point. The pump directs stored in the system, water is piped to the sewer system structure. For this purpose in the cover of the audit holes sewer pipe mount input, through which the water from the pump enters the sewer system structure. To prevent the formation of the hydraulic tube into the sewer pipe, the input is fixed to the cover oriented so that the spray was directed along the common drain sewage.

The pump connection with the sewer system of the house leads to the following technical result. Due to low systemic surges that occur in the system when the pump is cleaned pipes and connections sewer system at home of toxins and fat deposits. This reduces the frequency of required audit work and extend SL is gby pipelines.

Due to the automatic activation and deactivation of the pump is set to the desired water level in the composite filter well, allowing you to dry the top layer of basement soil to a depth of 600 mm to 1200 mm

In case of emergency shutdown of the pump drained soil absorbs the incoming water, the water level in the basement can reach emergency only after 3-5 days. This is enough to eliminate accidents in accordance with regulations.

Pump with low performance, it switches on only when raising the water level in precast-filterable well up to a certain point and shutting off when the water level decrease to a predetermined level, provides a slow removal of water from the system. What if the basement dehumidification occurs scouring from under the Foundation.

In General, the regulation of the water level in the basement of the house with the help of the proposed system is achieved by the strengthening of the Foundation. Coming from the external ground water carries particles of soil. Due to the slow exhaust and filters, the water velocity decreases. Since the specific weight of the soil is higher than the specific weight of water, the soil particles are trapped. Thus, there is compression of the soil under the Foundation and the entire area of the basement. Also stop growing cracks in the structure. In addition, the resiny Foundation which sources of water in the basement, clogged brought water with soil and water come into the basement less.

The result over time is achieved by reducing the frequency of inclusion of the pump and reducing the implementation cost of dewatering.

The implementation of the invention

The ground of the basement of the house mark and develop drainage channels.

Also dig the mine for prefabricated filter well and install it.

The specified combine well with all drainage channels.

Drains are placed filter material, such as gravel. In the composite filter well set the pump provided by the machine on and off, cover well vandal-proof lid.

From the outlet of the pump to the sewer pipe at home spend a flexible hose. To cover the audit holes secure the flange length of 200 mm, aimed in the course of draining the water in the pipe. A flexible hose attached to the flange.

Examples

The area enclosed by the Foundation of a house is 720 m2. The soils formed in fine-grained sand. Develop drainage channels with a width of 0.4 m, a depth of 1.2 m Channels covered with gravel fraction 20-40 mm. Develop the soil under the mine drainage wells with diameter of 2 m and a depth of 2 m it is mounted drainage-diameter well 0,63 m, depth 2 m, premeiotic between the wall of the well and the wall of the mine poured gravel fraction 20-40 mm. In a well establish drainage pump capacity of 200-400 watts. The output of the pump through a hose with a diameter of 32 mm is connected with the sewer pipe at home. For this to cover the audit holes secure the flange length of 200 mm, directed so that the spray was directed along the common drain. As a result, the ground of the basement dried at 60 cm depth.
