Construction method and structure for steel sheet pile support inner bracing
The invention relates to a construction method and structure for a steel sheet pile support inner bracing. The method comprises the steps that hot-rolled H-shaped steel is welded on the outer sides of Lassen U-shaped steel sheet piles to form steel frame stand columns; the steel frame stand columns and the steel sheet piles are driven into the two sides of a foundation pit symmetrically; a first steel frame beam is erected on every two symmetrical steel frame stand columns, and a second steel frame beam is erected on every two adjacent steel frame stand columns to enable the whole foundation pit support inner bracing to form an overall steel frame structure. According to the construction method and structure for the steel sheet pile support inner bracing, the beams are erected at the tops of the steel frame stand columns directly without mounting of members such as carry plates additionally, so that the process is simple, and the construction speed is high; the construction method and structure can be universally applied to support engineering of foundation pits such as building foundation pits and pipeline foundation pits, which are not high in underground water level and not too wide; a good effect can be achieved for foundation pit engineering bad in geological soil layer and high in strength and stability requirement for the inner bracing particularly; meanwhile, the advantages of the inner bracing can also be brought into play for the foundation pit support engineering urgent in required construction period.
