Description

Foundation pit supporting device for preventing foundation pit from collapsing Technical Field The utility model relates to the field of foundation pit support, in particular to a foundation pit support device for preventing a foundation pit from collapsing. Background The foundation pit support is used for ensuring the safety of underground structure construction and the surrounding environment of the foundation pit, and is used for supporting, reinforcing and protecting the side wall of the foundation pit and the surrounding environment. The existing foundation pit supporting device is relatively simple, in most cases, the supporting plate is used for supporting the side wall of the foundation pit, the inclined supporting rod is used for supporting the supporting wood plate, when the foundation pit is deeper, the length and the size of the supporting wood plate are limited and cannot be adjusted, and then the supporting effect is difficult to achieve. Chinese patent discloses a foundation ditch strutting arrangement that prevents foundation ditch from collapsing (grant bulletin number CN 220746944U), and this patent technique can solve when the foundation ditch is darker, in the direction of height, first dead lever top and bottom have better perpendicular and foundation ditch lateral wall's supporting role to the backplate, and the middle part of first dead lever is weak relatively to the supporting role of backplate, if the middle part soil layer of foundation ditch lateral wall takes place to collapse, extrudes the backplate, very easily causes the middle part of first dead lever to the inboard crooked of foundation ditch, takes place dangerous scheduling problem. If the dust is too big in this patent foundation ditch, then inhale by the human body easily and cause harm, and the subaerial watering is easy to spill on the foundation ditch inside wall, leads to its risk that takes place to collapse to it is difficult to detect whether the foundation ditch has the problem of risk of collapsing subaerial. Disclosure of utility model In order to solve the technical problems, the utility model provides a foundation pit supporting device for preventing a foundation pit from collapsing, which comprises a foundation pit and a positioning column, wherein the positioning column is inserted into the inner bottom of the foundation pit through a first bolt, a protection plate is arranged on the outer side wall of the positioning column through a connecting frame, the bottom of the protection plate is inserted into the inner bottom of the foundation pit through a plurality of second bolts, a water tank is arranged on the upper end surface of the positioning column, a water pump is arranged at the bottom of the water tank, a spring pipe is arranged at the bottom of the water pump, and a spray head is arranged at the other end of the spring pipe. Preferably, the outer side wall of the positioning column is provided with a protection cavity, and a spray head is arranged in the protection cavity in a clamping manner.
