Shakeproof lift-preventing anti-bending preformed pile and manufacturing process of preformed pile

Abstract

The invention relates to a shakeproof lift-preventing anti-bending preformed pile and a manufacturing process of the preformed pile. The preformed pile is characterized by comprising a plurality of prestress main bars, concrete, end plates on both sides and circular truncated cones matched with the prestress main bars, wherein the prestress main bars are uniformly arranged in the preformed pile, and adjacent prestress main bars encircle a circle through stirrups. The concrete is filled around the prestress main bars and the stirrups to form the preformed pile. The end plates are provided with through holes threaded with the prestress main bars which pass through the through holes on the end plates and are matched and connected with the circular truncated cones arranged on the other sides of the end plates. The invention provides the novel preformed pile and the manufacturing process thereof. Demands such as connection and piling of piles are realized through special connectors. The preformed pile has the advantages that the performed pile is simple in structure, convenient to operate and quick to construct, and the preformed piles can be firmly and accurately connected, so that the work efficiency is greatly improved, and the performed pile is labor-saving and the like.

Description

technical field [0001] The invention relates to an earthquake-proof, pull-out, and bending-resistant prefabricated pile and a manufacturing process of the prefabricated pile. Background technique [0002] With the great development of the city and the increase of the speed of economic construction, various buildings (structures) continue to stand up in the city. While the height of the building is becoming higher and higher, the pile foundation is widely used because of its excellent performance. In high-rise and super high-rise buildings (structures). The length of the pile in the pile foundation is also continuously lengthened. However, for the prefabricated pile, due to the length of the vehicle in transportation and the limitation of the height of the piling machine on the piling site, it is impossible to make the prefabricated pile in the factory too long. When a single prefabricated pile When the length is greater than 20 meters, its transportation and piling will bec...

AI Technical Summary

Problems solved by technology

The general prefabricated piles are mainly under pressure, even if the welding quality meets the general requirements, but in this case, it is very likely that the welding position of the two prefabricated pile end plates will be cracked, and the integrity of the pile will be severely affected. The impact will cause the prefabricated piles to fall off and float up and the ground buildings to float up or collapse, which will seriously endanger the safety of buildings and the lives and properties of the people.
