Description
Technical field
The utility model relates to civil construction project technical field more particularly to a kind of foundation pit side-wall infiltration current-collecting devices.
Background technique
Base pit engineering appears widely in architectural engineering, and pattern foundation pit supporting structure security relationship is smoothly implemented to engineering, because
Foundation pit side-wall, which seeps water, causes many insecurity factors to foundation pit supporting construction, and infiltration also will affect ground in foundation pit, and there are one
Fixed security risk.Sump, gutter can be arranged in bottom in usual foundation pit, but the way is mostly just for bright water, to base
Water extravasation does not act on substantially in the side wall soil of hole.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of foundation pit side-wall infiltration current-collecting device, the present apparatus is effective
Foundation pit side-wall seepage problem is solved, the influence seeped water to pattern foundation pit supporting structure safety and infiltration to foundation pit ground is avoided, it is hidden to prevent safety
Suffer from, it is ensured that the safe construction of foundation pit.
In order to solve the above technical problems, the utility model foundation pit side-wall infiltration current-collecting device includes several soakaway trench, catchments
General pipeline, several outlet pipes and several sumps, several soakaway trench intervals are embedded in foundation pit slope protection bottom and are communicated in
The water header outside foundation pit slope protection, several outlet pipes connect the water header by three-way connection interval, described
Several sump intervals are set to outside foundation pit slope protection, and several outlet pipes are connected to several sumps.
Further, the infiltration tube wall opens up several water seepage holes, and the water seepage hole covers filter cloth.
Further, the present apparatus further includes water-stop glue band, and the water-stop glue band avoids the water seepage hole and is wound in the infiltration
Pipe outer wall.
Further, burial place of the soakaway trench in foundation pit slope protection is within the scope of the above 800mm of absolute altitude of foundation pit bottom.
Further, the spacing of several soakaway trench is 1.5~5m.
Further, the spacing of several outlet pipes and several sumps is 15~30m.
Since the utility model foundation pit side-wall infiltration current-collecting device uses above-mentioned technical proposal, i.e. the present apparatus includes several
Soakaway trench, water header, several outlet pipes and several sumps, several soakaway trench intervals are embedded in foundation pit slope protection bottom and company
The logical water header outside foundation pit slope protection, several outlet pipes connect water header, several sumps by three-way connection interval
Interval is set to outside foundation pit slope protection, and several outlet pipes are connected to several sumps.The present apparatus effectively solves foundation pit side-wall seepage problem, keeps away
Exempt from the influence seeped water to pattern foundation pit supporting structure safety and infiltration to foundation pit ground, prevents security risk, it is ensured that the safe construction of foundation pit.
Detailed description of the invention
The utility model is described in further detail with embodiment with reference to the accompanying drawing:
Fig. 1 is the utility model foundation pit side-wall infiltration current-collecting device structural schematic diagram；
Fig. 2 is the A-A direction view of Fig. 1.
Specific embodiment
Embodiment is as depicted in figs. 1 and 2, and the utility model foundation pit side-wall infiltration current-collecting device includes several soakaway trench 1, collection
Supply mains 2, several outlet pipes 3 and several sumps 4, several intervals of soakaway trench 1 are embedded in 5 bottom of foundation pit slope protection and company
The logical water header 2 outside foundation pit slope protection 5, several outlet pipes 3 described in the connection of three-way connection interval by catchmenting
General pipeline 2, several intervals of sump 4 are set to outside foundation pit slope protection 5, and several outlet pipes 3 are connected to several sumps 4.
Preferably, 1 tube wall of soakaway trench opens up several water seepage holes, and the water seepage hole covers filter cloth.
Preferably, the present apparatus further includes water-stop glue band, and the water-stop glue band avoids the water seepage hole and is wound in the infiltration
1 outer wall of pipe.
Preferably, burial place of the soakaway trench 1 in foundation pit slope protection is within the scope of the above 800mm of absolute altitude of foundation pit bottom.
Preferably, the spacing of several soakaway trench 1 is 1.5~5m.
Preferably, the spacing of several outlet pipes 3 and several sumps 4 is 15~30m.
In the present apparatus, pvc pipe is can be used in soakaway trench and water header, does not do concrete shield on earth in foundation pit slope protection excavation
When wall, aperture makes soakaway trench on pvc pipe, and the filter cloth of good water permeability is wrapped up on the outside of water seepage hole, prevents soil from entering in pipe
Influence infiltration effect；Water-stop glue band is wound on the outside of the pore-forming of pipe before embedded soakaway trench, is constructed and is completed in foundation pit concrete guard wall
After effectively water can be prevented to ooze out outside tube wall；Soakaway trench interval is embedded in foundation pit slope protection, has been poured to foundation pit concrete guard wall
At and after concrete guard wall reaches some strength, soakaway trench is connect with water header using three-way connection；Water header is every
One outlet pipe is set every 15~30m and is connected to sump, water pump outlet is set in sump.
The present apparatus carries out water conservancy diversion discharge using soakaway trench and water header, effectively for situation is seeped in the outer water of foundation pit side-wall
Influence of the infiltration to foundation pit retaining wall safety and infiltration to foundation pit ground is solved, to prevent security risk, it is ensured that the safety of foundation pit
Construction.
