The invention relates to the construction of buildings and structures, namely to improve building conditions during the construction of underground parts in the pits and their protection during the operational period from flooding groundwater perched.

Closest to the proposed solution is the drainage of closed type, containing a trench deep-laid with the construction of wells for revision of the drainage system and slope of not less than 0,005% in the direction of the water discharge, in which the layer of gravel is placed perforated in the side surfaces of the pipes (ceramic, concrete, asbestosattorney diameter 125-300 mm), and fill the trench in layers-thickened layer of local soil, gravel, coarse sand to cover its local ground (Telichenko V.I., Lapidus A., Terentyev O.M. Technology of construction processes. Part 1. Moscow, Higher school, 2002, p.56-57) [1].

The disadvantages of this system are not guaranteed protection of pits in the construction period and built underground parts of buildings and structures in the operational period from flooding groundwater perched; a large amount of excavation for drainage trench with the specified minimum gradient of 0.005%; the wide range and flow rate of filter materials; complex technology; greater complexity and cost of works.

Task and the gain is to increase the efficiency of the closed drainage system both in terms of construction, and during operation of underground parts of buildings and structures during flooding groundwater perched, as well as reducing the amount of ground works for the drainage trenches, reducing the range and flow rate of filter materials, improving the manufacturability of the building process, reducing the complexity and cost of works.

To solve the problem in the known drainage of closed type, containing a trench deep-laid with a slope towards the discharge of drainage water, in which the layer of filter material is placed perforated pipes 125-300 mm, wells for revision of the drainage system, filling drainage trenches, filter materials according to the invention the perforated drainage pipes made in their tray part, the drainage trench fill homogeneous filtering material, the bottom of the trench is performed with a gradient of 0.003-0,004%, thus isolate waterproof film together with the wall of the trench from the side of the pit or outer face of the underground part of the building, as well as shelter roof filtration backfill drainage trenches or under the sole of the blind area of the construction.

The essence of the proposed solution are presented in the drawings, in which figure 1 is given a General solution drainage, including ring-fencing of the construction pit, and figure 2 - pristene the drainage underground part of the building.

The depth of the drainage pipe, the area of its tray surface, the diameter, number and location of holes, perforations and granulometric composition of the filtration material backfill drainage trench is determined by known methods of calculation depending on the form of dried soil, coefficients, filtering, gravity loss and inflow of groundwater perched.

Implementation of the proposed solution private drainage as follows. To provide more robust protection of the pit 1 and the underground part of the building 2 from flooding groundwater perched in the construction and operational periods in drained soil 3 form a drainage trench 4, coarse fill material filtration backfill 5, in which lay the drain pipe 6 with perforations 7 in the tray part 8. The bottom 9 of the drainage trench 4, the side surface 10 from the side of the underground part of the building 2 (or the outer surface 15 of the underground part of the building 2) and the roof 11 filtration backfill 5 under the sole backfill local soil cover 12 of the trench 4, or under the sole of the blind area 13 underground part of the building 2 wall drainage isolate waterproof film 14.

Filtration inflow of groundwater into the drainage pipeline is od 6 through the perforations 7 in its tray portion 8 prevents the process of silt in it and increases the velocity of the flow of drainage water in the pipe, which reduces the resistance Samotechnaya their flow and allows you to take the minimum slope of the drainage pipe 6 and the bottom 9 of the drainage trench 4 in the range from 0.003 to 0.004%, depending on the physico-mechanical characteristics drained soil 3.

Waterproof film 14 used in the proposed drainage of the closed type to prevent transit groundwater seepage, when a large flow through the drainage trench 4 trench 1 or underground part of the building 2.

Thus, the proposed solution provides the efficiency of a closed drainage both in terms of construction, and during operation of the underground part of the building during flooding them perched groundwater, as well as by reducing the minimum slope of the drainage pipeline reduces the amount of excavation in the drainage trenches, the consumption of filter materials and their nomenclature, improves the manufacturability of the construction process, reduces the complexity and cost of works.

Drainage of closed type, containing a trench deep-laid with a slope towards the discharge of drainage water, in which the layer of filter material placed perforated pipes, wells for revision of the drainage system, characterized in that the tube is made with a perforation in the tray part and placed in a homogeneous filter is in store material, and the bottom of the trench is made with a slope of 0.003-0,004% waterproof and insulated film together with the wall of the trench from the side of the pit or on the outer surface of the underground part of the building, as well as shelter roof filtration backfill drainage trenches or under the sole of the blind area of the construction.
