Abstract
The invention discloses a foundation pit support structure. The side surface of a foundation pit is supported by a spray anchor net; the spray anchor net is provided with an anchor pipe and inserted into the side surface of the foundation pit; multiple prestressed tubular piles are inserted into the side surface of the foundation pit from the top of the side surface of the foundation pit; the bottoms of the prestressed tubular piles are embedded at the bottom of the foundation pit; the prestressed tubular piles are vertical to the horizontal plane; the spray anchor net is divided into an upper half part and a lower half part at the waist of the side surface of the foundation pit; the upper half part of the spray anchor net is parallel to the prestressed tubular piles and clings to the prestressed tubular piles; and the lower half part of the spray anchor net is in a slope structure attached to the bottom of the side surface of the foundation pit. In the invention, multiple prestressed tubular piles are inserted into the side surface of the foundation pit from the top of the side surface of the foundation pit, thus the support strength is higher, and the potential safety hazards are avoided.
Description
Technical field
The present invention relates to foundation pit supporting construction.
Background technology
Foundation pit supporting construction as shown in Figure 1, general, foundation ditch 1 side is by 2 supportings of spray anchor net, and spray anchor net is provided with anchor tube 3 and inserts inside, foundation ditch side.Such foundation pit supporting construction, supporting intensity is not high enough, has potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of foundation pit supporting construction, and supporting intensity is high, avoids potential safety hazard.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of foundation pit supporting construction, and the foundation ditch side is by shotcrete rock bolt wire mesh support; Spray anchor net is provided with anchor tube and inserts inside, foundation ditch side; It is characterized in that: some pile for prestressed pipe insert inside, foundation ditch side from the foundation ditch side top, and the foundation ditch bottom is imbedded in the pile for prestressed pipe bottom, and pile for prestressed pipe is vertical with horizontal plane; Waist location is divided into the first half and the latter half to said spray anchor net in the foundation ditch side; Wherein, the first half spray anchor net is parallel with pile for prestressed pipe and be close to pile for prestressed pipe, and the latter half spray anchor net is that ramp structure is fitted in the foundation ditch side bottom.
As preferably, laterally arrange from top to bottom two rows and two row's anchor tubes of said spray anchor net anchor tube all spray the anchor net with the first half and fix.
Some pile for prestressed pipe insert inside, foundation ditch side from the foundation ditch side top among the present invention, thereby supporting intensity is higher, avoids potential safety hazard.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is further described:
Fig. 1 is a prior art supporting and protection structure sketch map;
Fig. 2 is a supporting and protection structure sketch map of the present invention.
The specific embodiment
As shown in Figure 2, specify foundation pit supporting construction of the present invention, foundation ditch 1 side is by 2 supportings of spray anchor net; Spray anchor net is provided with anchor tube 3 and inserts inside, foundation ditch side; Some pile for prestressed pipe 4 insert inside, foundation ditch side from the foundation ditch side top, and the foundation ditch bottom is imbedded in the pile for prestressed pipe bottom, and pile for prestressed pipe is vertical with horizontal plane; Waist location is divided into the first half and the latter half to said spray anchor net in the foundation ditch side; Wherein, the first half spray anchor net is parallel with pile for prestressed pipe and be close to pile for prestressed pipe, and the latter half spray anchor net is that ramp structure is fitted in foundation ditch 1 side bottom.Laterally arrange from top to bottom two rows and two row's anchor tubes of said spray anchor net anchor tube all spray the anchor net with the first half and fix.
Claims (2)
1. foundation pit supporting construction; Foundation ditch (1) side is by the supporting of spray anchor net (2), and spray anchor net is provided with anchor tube (3) and inserts inside, foundation ditch side, it is characterized in that: some pile for prestressed pipe (4) are inner from foundation ditch side top insertion foundation ditch side; The foundation ditch bottom is imbedded in the pile for prestressed pipe bottom; Pile for prestressed pipe is vertical with horizontal plane, and waist location is divided into the first half and the latter half to said spray anchor net in the foundation ditch side, wherein; The first half spray anchor net is parallel with pile for prestressed pipe and be close to pile for prestressed pipe, and the latter half spray anchor net is that ramp structure is fitted in foundation ditch (1) side bottom.
