Problems solved by technology

[0003] In the existing technology, concrete and steel structure support systems are used for the lateral support of deep foundation pits. The concrete support system needs formwork pouring during use, and repeated support and dismantling are carried out as the construction progresses. After removal, it cannot be used twice. use, and cannot be adjusted after the construction is completed; in addition, in the prior art, the steel structure support system is connected by screws, which is relatively simple and reusable in construction compared with the concrete structure, but it needs to be connected in the purlin structure of the foundation pit during construction. The screw is pre-embedded and welded, and it cannot be adjusted after the construction is completed.

Abstract

The invention relates to a deep foundation pit self-adaptive steel support adjusting system which comprises a plurality of supporting structures vertically connected in sequence, and each supporting structure comprises an enclosing purlin assembly, a pile body assembly, a steel supporting assembly and a detection assembly. The enclosing purlin assembly comprises four baffles, and the four baffles are located on the front side, the rear side, the left side and the right side of the steel supporting assembly correspondingly. According to the self-adaptive steel support adjusting system for the deep foundation pit, multi-directional telescopic adaptation of a steel structure support in the vertical direction and the horizontal direction is achieved, the repeated utilization rate is high, materials are saved, and in addition, the two connecting plates in the same connecting unit are fixed in multiple fixing modes through cooperation of the screws, the positioning columns and the positioning holes and clamping of the locking plates, so that the adaptability is high. In addition, accumulated water in the foundation pit can be conveniently discharged through the guide pipes on the baffles, and the guiding effect during the lifting period of the baffles is achieved through cooperation of the upper guide pipe and the lower guide pipe which are adjacent to each other.

Description

technical field [0001] The invention relates to a deep foundation pit self-adaptive steel support adjustment system, which belongs to the technical field of foundation pit support. Background technique [0002] The foundation pit is a soil pit excavated at the base design position according to the base elevation and the size of the base plane. Before excavation, the excavation plan should be decided according to the geological and hydrological data and the conditions of the buildings near the site, and waterproof and drainage work should be done. If the excavation is not deep, the method of placing the slope can be used to stabilize the soil slope, and the size of the slope shall be determined according to the relevant construction engineering regulations. If the excavation is deep and there are buildings nearby, the foundation pit wall support method, the shotcrete wall protection method, or even the underground diaphragm wall and the column-type bored pile interlocking me...
