Supporting structure

Abstract

The invention discloses a supporting structure which comprises a supporting wall. A protecting bar is arranged on the inner side face of one side of the supporting wall, made by a waterproof material and fixed on the supporting wall, a protecting wing is mounted on the lower surface of the supporting wall and fixed on the supporting wall, a laminated board is arranged in the supporting wall, the laminated board and the supporting wall are connected through a reinforcing bar, a reinforced concrete supporting column is mounted on one side of the laminated board and closely connected with the laminated board, a side wall is arranged on the other side face of the laminated board and positioned in the protecting wall, the supporting wall and the side wall are hermetically connected through cement mortar, and reinforcing force transmitting bodies are transversely mounted in the laminated board. The supporting structure is convenient for safe excavating of earthwork in the process of story adding construction of a basement, a newly-added supporting wall portion can be removed without influencing integral safety and reliability of the basement, and occupied space can be saved to greater extent, and the supporting structure is high in stability and has good supporting performance.

Description

technical field [0001] The invention relates to a supporting device, in particular to a supporting structure. Background technique [0002] In the foundation pit engineering in soft soil areas, due to the adjustment of the overall underground space planning of the region and the expansion of basement functions, the length and strength of the foundation pit support walls that have been constructed cannot meet the requirements for deepening the excavation depth of the foundation pit, and because the basement The space is generally very small. If the support structure takes up a large space, the basement space will be further reduced, which will make the construction more inconvenient. At the same time, the general support structure cannot support better, because the structure is not firm, and it is easy to use after long-term use. It will lead to fracture and subsidence, which will cause unnecessary losses in the construction process. In severe cases, it will easily lead to sa...

[0002] In the foundation pit engineering in soft soil areas, due to the adjustment of the overall underground space planning of the region and the expansion of basement functions, the length and strength of the foundation pit support walls that have been constructed cannot meet the requirements for deepening the excavation depth of the foundation pit, and because the basement The space is generally very small. If the support structure takes up a large space, the basement space will be further reduced, which will make the construction more inconvenient. At the same time, the general support structure cannot support better, because the structure is not firm, and it is easy to use after long-term use. It will lead to fracture and subsidence, which will cause unnecessary losses during the construction process. In severe cases, it will easily lead to safety accidents, which is not conducive to basement construction.
