Abstract

The invention provides a PC-method pile enclosure structure with Larssen piles of different lengths. The PC-method pile enclosure structure comprises steel pipe piles, the Larssen steel plate piles and connecting tongues, wherein the steel pipe piles and the Larssen steel plate piles are connected together through the connecting tongues, and the steel pipe piles and the Larssen steel plate piles are connected through the connecting tongues to form the combined enclosure structure; the steel pipe piles and the Larssen steel plate piles are distributed alternately, the steel pipe piles and the Larssen steel plate piles serve as the enclosure structure with water and soil retaining functions, the Larssen steel plate piles and the steel pipe piles are unequal in length, the Larssen steel platepiles are uniformly distributed between the steel pipe piles, and the steel pipe piles and the Larssen steel plate piles are uniformly distributed in a one-to-one or one-to-many manner. The PC-methodpile enclosure structure has the advantages of being large in pile body rigidity, good in water stopping effect, short in construction period and the like, the mechanism of common action of the pilesand soil is brought into full play, engineering materials are saved, the problem that Larssen steel plate piles are difficult to insert into certain sites is solved, and the enclosure structure has good popularization and application value.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a PC method pile enclosure structure of Larsen piles with different lengths. Background technique [0002] The P-C construction method pile (combination of steel pipe pile and Larsen steel sheet pile) has the characteristics of high rigidity of the pile body, wide application of strata, deep construction depth, remarkable water-stop effect, less environmental pollution, high-quality wall formation and recyclability. It is more and more widely used in foundation pit engineering in similar complex environments. [0003] The traditional P-C construction method piles are formed by setting Larsen steel sheet piles with the same length as the steel pipe piles between the steel pipe piles. loads and transfer loads to steel pipe piles. Although such P-C construction method piles are adopted by most projects, this method does not fully exert the action mechanism of pile soil, ...
