Embodiment Construction

[0010] Such as figure 2 As shown, the foundation pit support structure of the present invention is specifically described. The side of the foundation pit 1 is supported by the spray anchor net 2, and the spray anchor net is provided with an anchor pipe 3 inserted into the side of the foundation pit. The spray anchor net is at the waist of the foundation pit side The position is divided into the upper part and the lower part. A number of steel pipe piles 4 are inserted into the side of the foundation pit along the connection between the half part and the lower part of the spray anchor net. The bottom of the steel pipe piles is buried in the bottom of the foundation pit. vertical. The anchor pipes of the sprayed anchor net are arranged in three rows in parallel from top to bottom, wherein the first row of anchor pipes is fixed to the upper half of the sprayed anchor net, and the second and third row of anchor pipes are fixed to the lower half of the sprayed anchor net.

Abstract

The invention discloses a supporting structure of a foundation pit. The side face of the foundation pit is supported through a sprayed anchor net, the sprayed anchor net is provided with an anchor pipe inserted into the interior of the side face of the foundation pit and is divided into an upper half part and a lower half part in a waist-shaped part on the side face of the foundation pit; a plurality of steel pipe piles are inserted into the side face of the foundation pit along the part where the upper half part of the sprayed anchor net is connected with the lower half part; the bottoms of the steel pipe piles are embedded into the bottom of the foundation pit; and the steel pipe piles are vertical to the horizontal plane. According to the supporting structure of the foundation pit, the plurality of steel pipe piles are inserted into the waist-shaped part on the side face of the foundation pit through the sprayed anchor net, so that the supporting strength is higher, and the potential safety hazard can be avoided.

Description
