Description
Technical Field
The utility model relates to the technical field of supporting piles special for foundation pit excavation, in particular to a supporting structure for connecting a lock catch steel pipe pile and I-steel.
Background
The steel pipe pile has the advantages of high rigidity, small deformation, repeated use and the like, and is widely applied to foundation pit supporting engineering with deeper depth and higher deformation control requirement. Because the steel pipe pile supporting structures are not connected with each other generally, the conventional steel pipe pile structure is not provided with a water stopping function generally, and therefore in more underground water or water projects, some locking measures are required to be arranged on the steel pipe piles to ensure that the supporting structures have good water stopping effect. The common lock catch steel pipe pile is provided with a CT type lock catch and a Lasen type lock catch, the CT type lock catch steel pipe pile is composed of a steel pipe pile, a C type lock catch and a T type lock catch, the C type lock catch is made of a round steel pipe with a longitudinal through seam at one side, and the T type lock catch is made of a small-sized I-shaped steel. When the conventional CT type lock catch steel pipe pile is adopted as a supporting structure, the C type lock catch and the T type lock catch are only used as connecting sealing members between the steel pipe piles, the distance is smaller, the consumption of the steel pipe piles is larger, and the economical efficiency is lower for foundation pits with small depths and good soil properties.
