The invention relates to a protective walls, in particular drainage devices.

Known protective wall consisting of rows of piles; between the rows of piles placed drainage trench, the edges of which abut drainage wells [1] .

The disadvantage of this wall is the complexity and mnogodelnosti design, including drainage trench.

Also known drainage device containing the draining wall of the plates in the system, diverting drainage, adopted for the prototype [2].

A disadvantage of the known device is the complexity of its construction, as required hotcopy trench with fastening walls and dewatering.

the device, includes composite drainage wall system and the drainage outlet, a wall formed of Spontin, the upper and lower parts are made of thick concrete, and the middle - of draining porous concrete, between the middle and lower parts is a horizontal groove formed in the wall of the through-discharging channel.

The novelty of the claimed proposal due to the fact that due to the design features of the drainage wall is formed by immersion of the sheet than can be achieved reducing the complexity of the device horizontal drains, expansion opportunities draining relatively deep levels without the use of underground ways of laying drainage adits and galleries, eliminating the need for costly works on securing the walls of the trenches and dewatering.

According to the patent and technical literature is not detected by the claimed combination of features that allows us to judge the materiality of the claimed features.

In Fig. 1 shows a portion of the drainage device of Fig. 2 - projection of Spontini, including upper and lower part, made of thick concrete and the middle part of the porous concrete.

Drainage device PE 2 and lower part 3 of Spontin made of dense concrete, while the average 4 - from draining porous concrete. Between the bottom 3 and secondary 4 parts is a horizontal groove 5, formed in the wall of the through-discharging channel.

The drainage device is constructed and operates as follows.

On the site where you want to hold water or to intercept and divert groundwater flow in conditions, when the passage of the trench is connected with the necessity of fastening, and the drainage device is possible only under condition of preliminary dewatering, since the terrain or from the recipient device, and submerged piling or vibration each other of spuntini 1, forming a drainage wall, controlling the matching slots 5 and providing the slope of the end-to-end discharging channel that goes to the recipient. The lower part 3 of Spontin deepened in the confining bed and the average offer in the aquifer. Due to the difference of the conductivity in the draining part of the wall having a line of depression and dewatering.

Drainage device comprising a composite drainage wall system and diverting drainage, characterized in that the wall consists of Spontin, the upper and lower parts are made of thick concrete, and the middle - of pores is in the wall through horizontal discharging channel.

SUBSTANCE: invention is related to construction, namely to fighting suffosion processes that occur during flooding of earth foundations in buildings, which are for instance, located in high-water bed. In method for protection of building earth foundations against suffosion processes that occur as a result of building flooding, wells are drilled in building foundations, soil in wells is sampled, specimens obtained are used to determine value of critical head gradient and critical seepage path. Water impermeable wall is erected in building earth foundation around the base, at that distance between the base and water impermeable wall, as well as depth of water impermeable wall location from daylight is selected depending on values of critical gradient and critical seepage path. Space between building base and water impermeable wall is filled with water permeable material consisting of single-size particles, and space between the base in the level of its underside and water impermeable wall is filled with the layer of water impermeable material. Drainage holes with meshes are arranged at internal edge of water impermeable wall in water impermeable layer, and filling with layer of water impermeable material is done with layer separation into sections, in every of which surface is arranged with slope to drainage hole providing water drain into hole.

SUBSTANCE: method of protecting sunken buildings against ground water underflooding consists in the fact that distribution sand cushion is formed, highly compressed silty-clayed soils are removed from the whole underground part of buildings. When constructing underground parts of erected buildings on natural slopes in silty-clayed soils with high level of ground water, above lower boundary of design compressed mass of ground foundation, there developed is ditch, from the depth of lower boundary of compressed mass corresponding to level of lower edge of distribution sand cushion to day surface, the slopes of which correspond to position of planes of lower side edges of design distribution sand cushion which is formed as filtration one and designed in the outline of diagrams of equal vertical and horizontal stresses corresponding to stress of natural soil in lower part of compressed mass. Height of cushion is taken equal to design depth of compressed soil mass, and width of upper and lower edges of cushion is equal; at that, it exceeds width of foundation base on both sides by the value which is determined by graphical drawing of planes tangential to diagram of equal horizontal stresses at an angle to vertical plane, which is equal to angle of internal friction of cushion material to the crossing with plane of foundation base level. Position of side edges of cushion is determined by the planes being drawn from extreme points of upper and lower edges of cushion, which are tangential to diagrams of equal vertical and horizontal stresses till they cross each other; at that, inclination angle of tangential plane to diagram of equal vertical stresses is taken equal to angle of natural slope of natural soil. Then there formed is lower body of cushion in the volume of ditch slopes and upper body of cushion in the volume of upper side edges of cushion; after that, there performed is backfilling of cavities between upper cushion body and ditch slopes with natural soil as per layer-by-layer technology; then underground part of buildings is erected.

EFFECT: maintaining natural hydrological conditions in order to exclude dangerous ground water underflooding of underground parts of buildings, decreasing the scope of ground works concerning development of ditch, reducing material consumption.
