Steel sheet pile supporting structure and supporting method

Abstract

The invention relates to a steel sheet pile supporting structure and method, and relates to the field of building construction.The steel sheet pile supporting structure comprises two rows of stand columns which are oppositely arranged, a plurality of cross beams are fixedly connected to each row of stand columns, and the length direction of the cross beams is parallel to the arrangement direction of each row of stand columns; the cross beams are arranged in the height direction of the stand columns, a plurality of supporting beams arranged in the length direction of the cross beams are arranged on the cross beams, and the two ends of each supporting beam are fixedly connected with the cross beams at the same height position on the two rows of stand columns respectively; a baffle used for blocking the space between the stand column and the cross beam is arranged between the stand column and the cross beam. The method has the advantages that the supporting structure strength is improved, the safety of structural supporting construction in the deep foundation pit is improved, and the construction progress is guaranteed.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a steel sheet pile support structure and a support method. Background technique [0002] At present, a foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane size. It is the foundation of component buildings, and foundation pit engineering has become an indispensable and important link in building construction. Foundation pit support is an important measure to ensure the safety of underground construction. [0003] In related technologies, common foundation pit enclosure structures include underground diaphragm walls, perfusion occlusal piles or steel sheet pile support structures. [0004] In view of the related technologies mentioned above, the inventor believes that: the underground diaphragm wall and the perfusion occlusal pile have the problem of insufficient lateral rigidity, and at the ...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that: the underground diaphragm wall and the perfusion occlusal pile have the problem of insufficient lateral rigidity, and at the same time, the support performance is poor, the construction is difficult, the cost is high, and it is difficult to dismantle in the later stage; the general steel sheet pile Support is mainly to drive single steel sheet piles side by side into the ground, and then carry out earthwork excavation. However, when supporting structures in deep foundation pits, the construction of steel sheet piles is likely to cause increased deflection and deformation after excavation, and soil movement, resulting in surrounding Ground settlement has a certain impact on the safety and progress of construction
