Lock catch steel pipe pile and cofferdam construction method
The invention relates to the technical field of cofferdam construction, in particular to a lock catch steel pipe pile and a cofferdam construction method.The method comprises the steps that S1, a first steel pipe pile used for positioning is inserted and driven at the corner of a determined construction area; s2, the steel pipe piles are inserted and driven one by one along the first lock catch sides of the steel pipe piles used for positioning, and the second lock catch of the next steel pipe pile is inserted into the first lock catch of the previous steel pipe pile; s3, when the adjacent steel pipe piles are inserted into the same depth as the positioning steel pipe piles, the corresponding second lock catches and the first lock catches are locked to form sealing structures; s4, an inner supporting device used for supporting the steel pipe pile is arranged below the inner side of the steel pipe pile; s5, mud is sucked to the preset depth in the cofferdam; and S6, the bottom of the base in the cofferdam is sealed through underwater concrete. According to the invention, improvement is carried out on the basis of a C-O type lock catch; the angle of the supporting part is adjusted within a certain range, alignment is convenient during assembly, gaps are sealed through rubber parts in the assembly process, leakage is prevented, and the working efficiency is improved.
本发明涉及围堰施工技术领域，特别是涉及一种锁扣钢管桩及围堰施工方法，其包括S1、先在确定的施工区域的边角处插打第一根用于定位的钢管桩；S2、沿着用于定位的钢管桩上的第一锁扣侧逐一插打钢管桩，使下一钢管桩的第二锁扣插入上一钢管桩的第一锁扣中；S3、当相邻的钢管桩插入与定位钢管桩同一深度时，对应的第二锁扣与第一锁扣锁紧形成密封结构；S4、在钢管桩内侧下方用于对钢管桩进行支撑的内支撑器；S5、在围堰内吸泥至预定深度；S6、通过水下混凝土对围堰内基底进行封底。本发明通过在C‑O型锁扣的基础上进行改进；将支撑部在一定范围内调整角度，在进行装配时，方便对准，在装配过程中通过橡胶件将缝隙密封住，防止泄漏，提高了工作效率。
