a pile-wall integrated water-stopping lining-free foundation pit supporting structure of an underground intelligent parking lot comprises a concrete occlusion cast-in-place pile forming a closed loop; the bottom of the concrete occlusion cast-in-place pile is connected with an anti-floating bottom plate; a plurality of ring beams are arranged on the inner side wall of the concrete occlusion cast-in-place pile along the vertical direction; the top of the concrete occlusion cast-in-place pile is connected with a top ring beam; the slope surface is arranged on the outer side of the top ring beam in a surrounding mode, a drainage ditch is arranged on the outer side of the slope surface, and a hard covering top is arranged on the outer side of the drainage ditch; the slope surface is provided with a protective fence.
The sectional area of the ring beam is gradually increased from top to bottom along the vertical direction of the foundation pit.
The foundation pit is circular.
The concrete occluded filling pile is an integral structure formed by alternately connecting meat piles and vegetable piles.
The top ring beam is arranged right above the concrete secant cast-in-place pile and is connected with the slope surface.
The slope has a slope gradient of 3-4 degrees.
The bottom of the concrete occluded cast-in-place pile is embedded with anchoring steel bars, and the anti-floating bottom plate is connected with the concrete occluded cast-in-place pile through the anchoring steel bars.
The utility model has the advantages that:
1. a permanent support system formed by the secant pile and the ring beam can be used as a main structure, a lining wall in the main structure can be eliminated, and construction procedures are reduced.
2. The secant pile wall can effectively prevent the infiltration of underground water; the bottom plate of the lower parking lot structure can effectively resist the effect of underground water buoyancy through self weight and anchoring connection with the supporting structure.
3. The foundation pit supporting mode can form a construction template, a complete set of technology is formed, the pile diameter, the pile length and the like of the fender pile can be adjusted according to different stratums and the depth of the foundation pit, and the foundation pit supporting mode can be applied to other underground parking lot projects and is convenient to popularize and use.
