Bearing and enclosing system for foundation pit of super high-rise building

Abstract

The invention discloses a bearing and enclosing system for a foundation pit of a super high-rise building. The bearing and enclosing system comprises a foundation pit main body frame (1), wherein thefoundation pit main body frame (1) comprises an upper frame (2), a lower frame (3), supporting structures (4) and an enclosing wall (12); the upper frame (2) and the lower frame (3) are fixed and supported through a plurality of supporting structures (4); a plurality of bearing piles (5) extending into a foundation are arranged below the lower frame (3); the upper end of each bearing pile (5) is fixedly connected with the lower frame (3); the upper frame (2) and the lower frame (3) are provided with a plurality of transverse bearing structures (6) and longitudinal bearing structures (7) whichare positioned in a horizontal plane; and a transverse supporting structure (11) is connected between every two adjacent supporting structures (4). By the bearing and enclosing system, the water stopping effect on the foundation pit is effectively improved, the foundation pit is prevented from being damaged by settlement and deflection deformation of the super high-rise building, and the time forfinishing a construction period is optimized.

Description

technical field [0001] The invention relates to a building foundation pit support structure, which belongs to the field of soil engineering construction, and more specifically relates to a super high-rise building foundation pit load-bearing enclosure system. Background technique [0002] With the continuous development of urban construction, there are more and more various types of underground engineering and deep foundation pit engineering, and the construction method of deep foundation pit with high efficiency, economy, energy saving and environmental protection is particularly important. At present, the traditional deep foundation pit construction method is open construction, and its method is to excavate vertically after being surrounded by supporting structures or excavate with large slopes. After excavating to the design elevation, pour the reinforced concrete floor, then construct the basement structure layer by layer from bottom to top, and then carry out the constr...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, although the support structure of the foundation pit of a super high-rise building can prevent the springback deformation of the soil at the bottom of the foundation pit when the foundation pit is excavated, the support structure also has the following defects: The weight load will cause a certain deflection and deformation of the bottom plate of the foundation pit structure, and the diffused additional stress will also cause damage to the foundation pit structure
