Description

[Technical field]

[0001] The utility model relates to the technical field of pile foundation engineering, in particular to a quick connector for a pipe pile with elastic embedding. [Background technology]

[0002] At present, in the prior art, two adjacent pipe piles are mostly connected by welding. During the specific construction, it is necessary to first conduct an appearance inspection on the connection between the two adjacent pipe piles to ensure the final connection reliability of the pipe piles. After the inspection is completed, a jacket steel pipe is pre-welded on the lower section of the steel pipe pile, and then the upper section of the steel pipe pile is suspended and inserted into the jacket pipe, so that the pile head of the upper section of the pipe pile is connected with the end of the lower section of the steel pipe pile, and finally the two ends are welded and fixed. Since the upper section of the pipe pile and the lower section of the pipe pile both rely on welding to withstand external forces, it is necessary to inspect the quality of the steel pipe pile welding. In order to ensure a reliable connection, a large-area welding operation is required, resulting in low construction efficiency. [Contents of the utility model]

[0006] There are at least four embedded parts on one side of the fixed disc, and they are arranged opposite to each other in a group of two. An elastic steel plate is fixedly connected between the two oppositely arranged embedded parts.

[0007] Furthermore, the vertical limit rods are opposed to each other in pairs, and a reinforcing rod is connected between the two opposing vertical limit rods.

[0008] Furthermore, the thickness of the rubber sheet is 0.4-0.6 cm.

[0009] Furthermore, the length of the vertical limiting rod on one side of the fixed disc is 40±2 cm.

[0010] Furthermore, a circle of holes is provided on the fixed disc, and each of the vertical limit rods and the embedded parts are fixedly penetrated through the corresponding holes, that is, the vertical limit rods and the embedded parts corresponding to the upper and lower sides of the fixed disc are integrally formed.

[0011] Furthermore, a through hole is provided in the middle of the fixed disc.

[0012] Furthermore, the middle parts of the reinforcing rods located on the same side of the fixed disc are connected to each other.

[0013] The advantages of the utility model are:
