Description

A kind of basement waterproofing foundation pit structure and its construction method
Technical field
The present invention relates to building underground engineering field, and in particular to a kind of basement waterproofing foundation pit structure and its construction party Method.
Background technology
At present, similar Wuhan I grades of terraces diadactic structure geologic feature, the fine-grained sediment layer of top overbank phase, bottom is river The coarse grain sedimentary of bed phase, bottom is the geologic structure of rock stratum, to reach the effect of sealing, prevents periphery soil layer from drawing water sedimentation often In the following ways:1st, lithosphere or other clay water barriers are arrived in seepage proof curtain construction, are set according to design requirement before curtain Other retaining structures such as bored concrete pile;2nd, the cast-in-place diaphram wall that antiseepage and retaining structure are integrated, wall depth equally reaches Lithosphere or water barrier, while as water proof antiseepage and retaining structure, leakage preventing structure runs through the diaphram wall of whole Soft Soil Layer Underground water can effectively be completely cut off and pour in basement.This form of construction work has the following disadvantages:1st, diaphragm wall depth is big, construction cost Height, on the basis of hole bottom Resistant heave and stability requirement is met, usual diaphram wall, which will typically surpass, beats depth more than 2 to 4 times; 2nd, cast-in-situ wall is deeper, because degree control is more difficult, is difficult to ensure that into the big pouring quality of groove depth, so with causing adjacent width Weak part is easily formed at lower continuous wall connector;Cause percolating water hidden danger, cause surrounding ground to collapse and threaten foundation ditch stabilization.
