Description
Technical Field
The utility model belongs to the technical field of the construction technology and specifically relates to a basement bottom plate pressure relief device that dredges water.
Background
The conventional basement anti-floating design resists groundwater buoyancy through increasing structure bottom plate self bearing force, perhaps adopts the form of anti-floating stock or anti-floating pile to increase the bearing capacity of structure bottom plate, and above conventional construction method increases construction cost or causes the time limit for a project to increase, probably leads to basement bottom plate structural damage because actual water level is higher than the design water level moreover and causes basement bottom plate anti-floating not enough.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the invention aims to provide a basement bottom plate hydrophobic pressure relief device which can improve the construction efficiency, save the cost and reduce the risk.
The utility model discloses a realize through following technical scheme:
a basement bottom plate drainage pressure relief device comprises a water seepage pipe, a pebble water filtering layer, non-woven fabrics, a connector, a steel pipe, a water stop ring, a water collecting well and a bottom plate; the water collecting well is arranged below the bottom plate; the water seepage pipe is arranged below the bottom plate; pebble water filtering layers are arranged around the water seepage pipe; non-woven fabrics are wrapped around the pebble water filtration layer; the head end of the steel pipe is an elbow, and the pipe orifice faces the water collecting well; the tail end of the steel pipe penetrates through the bottom plate and is connected with the water seepage pipe through the connector; the water stop ring is welded in the steel pipe and is positioned in the bottom plate.
Furthermore, prevent that silt from getting into the drainage layer, blockking up the infiltration pipe, the non-woven fabrics of cobble drainage layer parcel all around is two-layer.
Further, the water seepage pipes are arranged below the bottom plate at intervals of 40-50 m.
Furthermore, plum blossom-shaped openings are formed in the water seepage pipe.
Further, the connector is a three-way connector.
The utility model has the advantages that:
the utility model discloses can replace conventional building basement anti design of floating, improve the efficiency of construction, simple structure is practical, practices thrift the cost, and reduces the risk.

Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1-3, the drainage and pressure relief device for the basement bottom plate of the present invention comprises a water seepage pipe 1, a pebble water filtration layer 2, a non-woven fabric 3, a connector 4, a steel pipe 5, a water stop ring 6, a water collecting well 7 and a bottom plate 8; the water collecting well 7 is arranged below the bottom plate 8; the water seepage pipe 1 is arranged below the bottom plate 8; pebble water filtering layers 2 are arranged around the water seepage pipe 1; the periphery of the pebble water filtering layer 2 is wrapped with a non-woven fabric 3; the head end of the steel pipe 5 is an elbow, and the pipe orifice faces the water collecting well 7; the tail end of the steel pipe 5 penetrates through the bottom plate 8 and is connected with the water seepage pipe 1 through the connector 4; the water stop ring 6 is welded in the steel pipe 5 and is positioned in the bottom plate 8.
Furthermore, the non-woven fabrics 3 wrapped around the pebble water filtering layer 2 are two layers.
Further, the water seepage pipes 1 are arranged below the bottom plate 8 at intervals of 40-50 m.
Furthermore, plum blossom-shaped openings are formed in the water seepage pipe 1.
Further, the connector 4 is a three-way connector.
The utility model discloses a theory of operation:
firstly, 200mm of phi PVC infiltration pipes 1 (plum blossom openings) are arranged on a bottom plate 8 of a basement vertically and horizontally at intervals of 40-50m, pebble water filtering layers 2 with the thickness of 300mm are arranged around the infiltration pipes 1, two layers of non-woven fabrics 3 are wrapped around the pebble water filtering layers 2 to prevent silt from entering the water filtering layers and blocking the infiltration pipes, a water infiltration pipe network is formed, stainless steel pipes 5 are connected near wells 7 collected by the basement through connecting lining plastic three-way connectors 4, water stop rings 6 are welded on the steel pipes 5 positioned in the bottom plate 8 to prevent underground water from leaking into the basement, the ends of the steel pipes 5 are provided with elbows, the mouths of the elbows are aligned to a water collecting well 7, according to an anti-floating design water level obtained by an early exploration unit, the height of the steel pipes 5 is lower than the designed anti-floating water level, and when the water level of the basement is higher than the anti-floating design water level, the basement is discharged into the water collecting well 7 of the basement through the steel pipes 5.
The above embodiments are merely illustrative of the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the same, and not to limit the protection scope of the present invention.
