Bolt-type connecting piece and connecting pile

Abstract

The invention discloses a bolt-type connecting piece and a connecting pile. The bolt-type connecting piece comprises a large nut sleeve, a small nut sleeve, an inserted rod and two bolts, one side of the inserted rod is connected with the small nut sleeve, the other side of the inserted rod is sleeved with the large nut sleeve, and an annular groove is formed in the peripheral surface of the portion, sleeved with the large nut sleeve, of the inserted rod; two sets of through holes which are used for being matched with the annular groove formed in the inserted rod are symmetrically formed in the side wall of the large nut sleeve; the two bolts penetrate through the through holes which are formed in the large nut sleeve and the annular groove formed in the inserted rod respectively, and the bolts are used for fixing the inserting rod and the large nut sleeve in a spacing mode. By means of the structural arrangement of the bolt-type connecting piece, the connection and fixation of an upper connecting pile and a lower connecting pile are achieved, and the technical problem that waggling exists between the upper connecting pile and the lower connecting pile which are fixedly connected is solved.

Description

Technical field [0001] The invention belongs to the technical field of construction, and specifically relates to a plug-type connector and a connecting pile. Background technique [0002] In the process of using pipe piles, it is necessary to select pipe piles of different lengths according to different use requirements, which requires that the pipe piles and the pipe piles are connected to each other to form a longer-length pile body. At present, the existing pipe piles are provided with steel plates at both ends, and the pipe piles and the pipe piles are connected by mutual welding. After the connected pile is pressed into the ground when the pile is pressed, the soil contains salt, especially chloride, which will corrode the steel plate exposed in the soil, causing the joint between the pipe pile and the pipe pile to break, thereby As a result, the connection between the pipe pile and the pipe pile is disconnected. In addition, the method of connecting through the welding of ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned solution improves the existing technology to a certain extent, but in this solution, when connecting the pipe piles, there is a gap between the two pipe piles, so that during the use of the pipe piles, there will be shaking between the two pipe piles. In turn, it will affect the connection strength between the two pipe piles, resulting in unqualified products
