Deep foundation pit supporting structure

Abstract

The invention discloses a deep foundation pit supporting structure. The deep foundation pit supporting structure comprises a soil nail retaining pile which is attached to the side wall of a foundation pit, wherein the outer side of the soil nail retaining pile is provided with a water stop supporting pile of which one end is embedded into a soil body under the foundation pit, the middle part of the water stop supporting pile is provided with a horizontal lateral-resisting top beam, and a lateral-resisting reinforcing pile is arranged below the lateral-resisting top beam. According to the deep foundation pit supporting structure disclosed by the invention, the soil nail retaining pile is attached to the side wall of the foundation pit for retaining soil, the water stop supporting pile can be used for preventing the water seepage of the pile body while being used for supporting the soil nail retaining pile, the lateral-resisting reinforcing pile which is additionally arranged at the outer side of the water stop supporting pile can be used for further supporting the soil nail retaining pile and the water stop supporting pile, the strength of the deep foundation pit supporting structure can be effectively ensured, better-quality and safer protection can be supplied for a deep foundation pit, and the deep foundation pit supporting structure disclosed by the invention is applied to the field of architectural structure construction.

Description

technical field [0001] The invention relates to a building construction structure, in particular to a support structure for a foundation pit. Background technique [0002] With the rapid development of high-rise buildings, the foundation pit will become larger and deeper, and the construction of the support structure of the foundation pit will become more and more difficult. In the construction process, in order to ensure the safety and convenience of the construction of the underground structure and the surrounding environment of the deep foundation pit, it is necessary to take support and reinforcement measures for the side wall of the deep foundation pit and the surrounding environment. [0003] At present, foundation pit support mostly adopts pile and anchor foundation pit support, soil nail wall, steel sheet pile, cement mixing pile and other support methods. However, often due to the complex environment around the construction site, the construction period is relative...

AI Technical Summary

Problems solved by technology

However, often due to the complex environment around the construction site, the construction period is relatively long, the construction method is relatively cumbersome, the cost of the support structure is also high, and the quality and safety of the structure is difficult to be guaranteed.
