Description
Technical field
The present invention relates to technical field of civil engineering, particularly relate to a kind of foundation pit supporting construction.
Background technology
Foundation ditch must cause the distortion of surrounding soil in digging process, has an impact to Adjacent Buildings and underground utilities.Serious will jeopardize it and normally use or safety, and carry out stable deep pit monitor in order to avoid this situation can increase support system in dark base design and hole construction, mainly contain three kinds of forms at present: to support, diagonal brace and reverse anchoring.
Support and be widely used in deep foundation ditch at present, but supporting to occupy cheats interior space in a large number, long construction period, is unfavorable for digging, and when the later stage removes, potential safety hazard is large, not only improves the cost of engineering but also be unfavorable for environmental protection.Reverse anchoring is the new technology in recent years promoted, the advantage of reverse anchoring is foundation ditch is uncovered open, but cut the earth and the little poor stability of the convenient easily generation Multi anchorage effect safety factor of structure construction, the construction technology loaded down with trivial details cycle is long, can not make full use of land resources because anchoring body exceeds land red-line.
Diagonal brace is used for the center ring island construction of super-giant foundation pit, have more economic advantages relative to supporting but need first at foundation ditch central excavation in construction, just diagonal brace construction can be carried out after construction of bottom plates completes, and must constuction joint be reserved when building structure construction, the loaded down with trivial details long construction period of program, the later stage removes and pattern handling difficulty.
Traditional pattern foundation pit supporting structure comprises base plate, base for supporting, support bar, bracing frame, rectangular tube and backplate, because the position of backplate and rectangular tube is indefinite, for ensureing the stability supported, therefore need scene to be welded one by one by steel plate under the base for supporting connected by support bar and the understanding and considerate condition of bracing frame, expend huge financial resource and material resource, along with the area of excavation of foundation pit and the degree of depth increasing, tradition support system has been difficult to the effect meeting safety economy, the sound construction degree of tradition support form and poor stability, and install and remove cumbersome, engineering quantity is large, cost is high, duration is longer.
Summary of the invention
In order to solve above-mentioned technical problem, the object of this invention is to provide a kind of structure simple, firm stable, and be convenient to the foundation pit supporting construction of assembling.
In order to realize above-mentioned object, present invention employs 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 invention has the beneficial effects as follows: 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 invention, is convenient to the tightness of adjustable supporting structure in addition, convenient efficient again; Base for supporting of the present invention 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.
