Description

A kind of deep basal pit base plate exterior wall blind drainage secondary utilizes structure

Technical field

This utility model relates to a kind of deep basal pit base plate exterior wall blind drainage secondary and utilizes structure, belongs to building construction technology Field.

Background technology

At present, along with China's economy growing, urbanization process quickly propel with land resource in short supply, high Layer, high-rise building have become a basic trend of urban architecture development.High-rise, high-rise building will use deep basal pit, And in the work progress of deep basal pit, a lot of in the case of, although subsoil water has been reduced to below the absolute altitude of substrate, but in substrate Or periphery still also exists the infiltration situation of fraction, badly influence the construction on basis, if continuing to use traditional foundation ditch Precipitation method, is not completely exhausted out the infiltration that this is a small amount of.The water adding discharge is not the most reasonably utilized, now In the epoch of global water resources shortage, water resource is to affect economic civilization as an important component part of whole ecological environment Life, the flourishing restraining factors in city are the closest with the relation of weather, weather again.The secondary of water resource utilizes and seems outstanding For important.In sum, it is badly in need of taking a kind of drainage measure that can be utilized by the water secondary discharged.

Summary of the invention

The purpose of this utility model is, it is provided that outside a kind of simple in construction, quick construction, safe and reliable deep basal pit base plate Wall blind drainage secondary utilizes structure, thus effectively solves substrate or the problem of periphery infiltration, is arranged by the water in deep basal pit simultaneously Go out and collect the measure utilized as secondary, reaching the purpose of saving water resource.

The technical solution of the utility model: a kind of deep basal pit base plate exterior wall blind drainage secondary utilizes structure, including deep base Hole base plate and exterior wall, arrange a french drain outside exterior wall, excavates a sump at french drain substrate absolute altitude lowest part, makes blind Ditch is connected with sump, finally places a water pump in sump, and water pump is connected with outside cistern by drain pipe.

Described french drain is followed successively by medium sand loaded filter, coarse sand loaded filter, corrugated tube, cobble loaded filter and coagulation from top to bottom Soil padding.

Being filled with particle diameter in the range of the borehole wall 1.5m of described sump is that 5～10mm cobbles or rubble are as drainage layer.

It is provided with steel deck-plate at the well head of described sump, steel deck-plate is opened in hole, the row being connected with water pump Water pipe from this hole by being connected through rear and outside cistern.

Owing to using technique scheme, the utility model has the advantage of:

1, relative to tradition Method on Dewatering of Foundation Pit, french drain, sump precipitation method that this utility model is used can be bases Hole seepage problem thoroughly solve, it is ensured that construction quality and the duration, saved construction cost；

2, the water in this utility model uses pump handle deep basal pit sump is evacuated to ground reservoir and makees secondary utilization, indirectly Ground is saved and protects the water resource of shortage.

Therefore, this utility model is not only simple in structure, quick construction, safe and reliable, thoroughly solves foundation ditch seepage problem, Water in deep basal pit is discharged and collected simultaneously the measure utilized as secondary, reach the purpose of saving water resource.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings with embodiment pair This utility model is described in further detail.

Embodiment of the present utility model: deep basal pit base plate exterior wall blind drainage secondary utilizes the structural representation such as figure of structure Shown in 1～3, including deep basal pit base plate 1 and exterior wall 2, a french drain 3 is set outside exterior wall 2, at french drain 3 substrate absolute altitude Lower one sump 4 of excavation, makes french drain 3 be connected with sump 4, finally places a water pump 10, water pump 10 in sump 4 It is connected with outside cistern 14 by drain pipe 13, this water pump 10 the most just can be utilized to be evacuated on ground by the water in sump 4 Cistern 14 in store, as the use washed one's hands, water flowers etc., to reach the purpose that secondary utilizes.Described french drain 3 is from top to bottom It is followed successively by medium sand loaded filter 9, coarse sand loaded filter 8, corrugated tube 7, cobble loaded filter 6 and concrete cushion 5.Described sump 4 Borehole wall 1.5m in the range of to be filled with particle diameter be that 5～10mm cobbles or rubble are as drainage layer 11.Further, described sump Being provided with steel deck-plate 12 at the well head of 4, be opened in hole on steel deck-plate 12, the drain pipe 13 being connected with water pump 10 is from this hole Hole is by being connected through rear and outside cistern 14.It addition, for prevent seepage outside subsoil water hole along steel deck-plate 12, can Sealing piece is welded in the middle part of steel deck-plate 12.
