Circular buckle plate mechanical pile splicing method for precast square piles

Abstract

The invention discloses a circular buckle plate mechanical pile splicing method for precast square piles. An end plate with a circular groove and an end plate with a circular protruding plate are spliced and are fixed at the two ends of two precast square piles to be butted respectively. First grooves are formed in the splicing position between the end plate with the circular protruding plate and the end plate with the circular groove, second grooves are formed in the splicing position between the end plate with the circular groove and the end plate with the circular protruding plate, and the first grooves and the second grooves are formed in a joint circle of the end plate with the circular groove and the end plate with the circular protruding plate. The end plate with the circular protruding plate and the end plate with the circular groove are spliced through connection accessories. According to the method, mechanical connection points can be reduced relatively, the connection reliability is improved, the foundation engineering potential safety hazard is reduced, and the building safety is further guaranteed.

Description

technical field [0001] The present invention relates to a mechanical pile connection method, in particular to a circular concave-convex plate mechanical pile connection for prefabricated pipe piles, which ensures the integrity of the end plate structure, reduces connection points, reduces potential safety hazards, and increases structure for prefabricated pipe piles. method. Background technique [0002] With the improvement of the importance of modern buildings and the diversification of structural forms, the requirements for foundation treatment in construction projects have been continuously improved. In the past, concrete square piles and concrete prefabricated square piles used in the foundation treatment of various buildings were used as the gap between the bearing layer and the upper structure. Most of the supporting and force-transmitting rods are used as permanent pressure-bearing piles, which mainly bear the vertical load. However, there are more and more undergrou...

Problems solved by technology

At present, most projects still use the welding method. After the piles are welded and connected, they need to be naturally cooled for 8-10 minutes before continuing to sink the piles, which wastes a lot of time and affects the efficiency of construction. Welding requirements, continuing to sink piles before the welding place cools down, greatly reduces the quality of the pile connection, and bury a great safety hazard for the entire project
