Lock catch steel pipe pile and foundation pit enclosure structure

Abstract

The invention discloses a lock catch steel pipe pile and a foundation pit enclosure structure. A first lock catch and a second lock catch are connected to the outer wall of a steel pipe of the lock catch steel pipe pile, and the first lock catch and the second lock catch are arranged in the axis direction of the lock catch steel pipe pile. In every two adjacent lock catch steel pipe piles, the first lock catch of one lock catch steel pipe pile is connected with the second lock catch of the other lock catch steel pipe pile in a matched mode. According to the lock catch steel pipe pile and the foundation pit enclosure structure, when a foundation pit is enclosed by connecting the lock catch steel pipe piles, the assembly operation is simple, the complex process of pouring a large number of occlusive piles and continuous walls in the traditional construction process is omitted, meanwhile, the lock catch steel pipe pile has the characteristics that materials can be obtained conveniently, and manufacturing is easy, the construction progress is accelerated, and the manufacturing cost is reduced; due to the fact that the lock catch steel pipe pile has extremely high replaceability and scene adaptability, repeated use is facilitated.

Description

technical field [0001] The invention relates to a locking steel pipe pile and an enclosure structure for a foundation pit. Background technique [0002] With the development of domestic infrastructure projects, foundation pits need to be excavated in many infrastructure projects. In order to carry out the construction projects smoothly in the later period, the excavated foundation pits will be protected. [0003] At present, most of the enclosures for foundation pits use occlusal piles plus MJS construction method water-stop curtains, or adopt the method of underground diaphragm walls. These conventional methods have the problem that they cannot be reused, and at the same time, a large amount of mud generated during the enclosure process will destroy On-site construction environment. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a locking steel pipe pile and foundation pit enclosure structure in order to overc...
