In order to realize above-mentioned object, the utility model have employed following technical scheme:
A kind of foundation pit supporting construction, comprise base plate, base for supporting, support bar, bracing frame, rectangular tube and backplate, described base for supporting comprises bed plate and the first contiguous block, and described first contiguous block becomes U-shaped by steel plate bending, and the U-shaped end face of side welds with bed plate; Described support bar comprises bar cover and expansion screw, the inwall at the two ends of described bar cover is provided with screw thread, two expansion screws screw in the two ends of bar cover respectively, one end that described expansion link exposes bar cover is also provided with one section of pipe, the lateral wall of pipe welds mutually with the termination of expansion link, and the axis perpendicular of the axis of pipe and expansion link; Support frame as described above comprises bracket and the second contiguous block, described second contiguous block becomes U-shaped by steel plate bending, described bracket entirety is bent into U-shaped frame construction by round steel, comprise connecting portion and location division, described connecting portion is two vertical bar round steel that interval is welded on bottom the second U-shaped contiguous block, and two vertical bar round steel are parallel with two sidewalls of the second U-shaped contiguous block respectively, two location divisions are the U-shaped round steel that opening two ends fix with same one end of two vertical bar round steel respectively; Two rectangular tube parallel interval are welded on the side of backplate, the inner side of the location division of described bracket fits with two rectangular tubes respectively, and pin runs through bottom and the backplate of the second contiguous block, pin sheet inserts pin near one end of backplate, bracket and backplate are fixed, described base for supporting is fixed on base plate, and the pipe at described support bar two ends is hinged with the sidewall of the first contiguous block and the second contiguous block respectively.
Preferably: the connecting portion of described bracket is mutually vertical with location division rounding off.
Compared with prior art, the beneficial effects of the utility model are: on the one hand technique is simple, cost of manufacture is low to have employed the bracket of transverse frame, pin easy to use and pin sheet realize bracket and being fixedly connected with between backplate, rectangular tube on the other hand, and the installation and removal of the connected mode of pin and pin sheet are all more convenient, do not affect again the firmness of supporting and protection structure simultaneously; Support bar adjustable in length of the present utility model, is convenient to the tightness of adjustable supporting structure in addition, convenient efficient again; Base for supporting of the present utility model is also welded by U-shaped steel plate and bed plate, and technique is simple, cost of manufacture is low, eliminates the trouble of Site Welding.
