Abstract

The invention discloses a three-limb type rigid combined supporting system, and relates to the technical field of foundation pit supporting, the supporting system comprises a first-layer supporting system and a second-layer supporting system, and the first-layer supporting system and the second-layer supporting system are connected into a whole through a connecting piece; the first-layer supporting system and the second-layer supporting system are both connected with bored piles, and the bored piles are connected with H-shaped section steel supports in the splayed supports in the first-layer supporting system and section steel enclosing purlins in the second-layer supporting system through I-shaped force transmission pieces correspondingly. The high-strength bolts are adopted to connect the multiple pieces of profile steel to form a support, compared with a traditional support, the joint strength is high, the rigidity is large, the stability is good, all parts can be prefabricated in a factory and rapidly installed and positioned on site, accuracy is achieved, meanwhile, the construction speed is guaranteed, and meanwhile the later-period disassembling process of the three-limb-shaped profile steel combined supporting system is convenient, simple and fast.

Description

technical field [0001] The invention relates to the technical field of foundation pit support, in particular to a three-leg-shaped rigid combination support system. Background technique [0002] In recent years, my country has continuously promoted the development of various underground spaces to alleviate the long-term congestion caused by excessive pressure on ground roads and improve the travel efficiency of the people. The key point of this type of underground engineering construction is the construction of deep foundation pits. In urban construction, the depth of some foundation pits has reached more than 30m, and the surrounding environment of foundation pits in the city is complex, with a large number of adjacent buildings and complex underground structures. Therefore, higher requirements are put forward for the safety and stability of the support structure in the foundation pit engineering. Common support types in foundation pit engineering mainly include concrete s...
