Embodiment Construction

[0016] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0017] see figure 1 In this embodiment, the foundation pit adopts an internal support structure, and the internal support is a steel structure beam 1, and the two ends of the steel structure beam 1 are supported on the purlins. The profiled steel is supported side by side, and the eight profiled steels are fixed to each other through the connecting plate horizontally, and the length is extended through the bolt connection in the longitudinal direction. The number of section steels contained in the steel structure beam 1 is selected according to the actual stress situation.

[0018] see figure 2 , on the longitudinal section of the foundation pit, there are three internal supports of the foundation pit, the first support 11 is a support of a l...

Abstract

The invention provides a superposed inner support structure for a foundation pit support. At least a superposed structure is arranged in the inner support structure, so that the requirements of pressure change of different-depth soil layers are met, the supporting stability is improved, the support number is reduced, the inner space of a foundation pit is enlarged, and the earthwork excavation and transportation and the construction of an underground main structure are convenient. With the superposed inner support structure, the purposes of shortening the construction period and reducing the engineering construction cost are achieved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an inner support structure for foundation pit support. Background technique [0002] In the foundation pit support structure, the internal support support structure is a commonly used support, mainly including reinforced concrete support and steel support. The existing steel inner supports are usually steel pipe supports and shaped steel supports, and their specifications and sizes change little. When encountering deep foundation pits with high earth pressure, the commonly used types of steel supports have limited bearing capacity, so it is necessary to find a safe Reliable and affordable support structures to meet load-bearing capacity requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a superimposed inner support structure for foundation pit support by overcoming the problem of small internal s...
