Convex extension part under, the length that the triangular plate is fixedly arranged on the side of the convex extension part is identical with the width of the convex extension part and be all higher than
The thickness of filtering layer 132.Floor 133 is used to reinforcing and protecting precipitation mechanism, and triangular structure can be in bearing diagonal 13 in insertion soil
Buffering is formed during body, prevents the soil body is excessive to the active force of the bottom of filter layer 132 from causing filter layer 132 to shift.
Suction pump 15 is connected with the top of drinking-water pipe 134, the inner vacuum of drinking-water pipe 134, by suction pump 15 and drawing water
Pipe 134 extracts the water entered inside bearing diagonal 13 out, so as to realize the precipitation to soil mass consolidation.
Matting layer 16 is located at the bottom of foundation ditch 10, at interior retaining piles 11, for increasing the supporting construction for foundation ditch
The supporting intensity of 10 bottoms.Preferably, the thickness of matting layer 16 is that 300mm, width are 8m.
Pier 17 is reinforced located at foundation ditch 10 and the corner portion of interior retaining piles 11 formation, for anchoring through interior retaining piles 11
Bearing diagonal 13 part, further increase the supporting intensity of the supporting construction.Preferably, the width of reinforcing pier 17 is
4700mm, highly be 4000mm.
In a preferred embodiment, foundation ditch is used to build the layer garage of underground two.Now, building of constructing is needed inside foundation ditch
In plate, gap of the floor load transfering strip 18 located at interior retaining piles 11 with foundation ditch 10, at floor.Preferably, floor load transfering strip
18 thickness are 200mm.
The construction method to foundation pit supporting construction of the present invention with precipitation function is illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1 there is provided interior retaining piles 11, interior retaining piles 11 are inserted in into the peripheral soil body of foundation ditch 10；
Outer retaining piles 12 are provided, outer retaining piles 12 are inserted in into the peripheral soil body of interior retaining piles 11, outer retaining piles 12
