Prefabricated assembled pier column structure connected by inserting steel bars into corrugated pipes and construction method thereof

Abstract

The invention relates to a prefabricated assembled pier column structure connected by inserting steel bars into corrugated pipes. The prefabricated assembled pier column structure comprises a bearingplatform, wherein a groove is formed in the upper surface of the bearing platform, a supporting column used for supporting the bottom surface of the pier column is arranged inside the groove, a plurality of corrugated pipes are vertically embedded in the periphery of the supporting column inside the groove, a plurality of main steel bars at the bottom of the pier column are in one-to-one correspondence with the corrugated pipes and are inserted into the corrugated pipes, inner filling layers are arranged inside the corrugated pipes, and concrete filling layers are poured inside the groove. Theprefabricated assembled pier column structure connected by inserting steel bars into corrugated pipes is simple.

Description

technical field [0001] The invention relates to a structure and a construction method of a prefabricated assembled pier column connected by inserting a corrugated pipe, and relates to the field of civil engineering. Background technique [0002] With the popularization of environmental protection and energy saving awareness, people have higher and higher requirements for the modernization of urban bridge construction. From urban residents to bridge designers and construction personnel, there are fast, safe, energy-saving and environmentally friendly construction of urban bridges. Small traffic disturbance, good construction quality and other requirements. Building prefabricated construction technology is the key to meet the above needs, and the prefabricated assembly technology of the bridge superstructure is quite mature, and construction and research personnel have gradually shifted their attention to the realization of the substructure prefabricated assembly technology su...

AI Technical Summary

Problems solved by technology

[0004] There are still many deficiencies in the existing connection methods of prefabricated bridge piers. For example, the bridge piers are spliced ​​with cast-in-place joints, the connection process of the main steel bars of the bridge piers is complicated, and the connection quality is not easy to guarantee; The construction tolerance of the barrel joint is small, and the construction accuracy is high. The two steel bars connected in the sleeve are likely to be too long and the other is too short due to construction errors, and the anchorage length of the too short line is not enough to cause the steel bar to be damaged. The risk of pulling out, the current method is not suitable for the connection of prefabricated structures in earthquake-resistant areas
