Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] see figure 1 , figure 2 with image 3 , the prefabricated assembled pier sequentially includes pile foundation 10, cast-in-place cap 30, prefabricated pipe pier 50 and prefabricated cap beam 70 from bottom to top; 10 platform, pile foundation 10 and cast-in-place cap 30 are buried below the ground; several prefabricated pipe piers 50 are vertically connected above the cast-in-place cap 30; The cap beam 70 is transversely connected to several prefabricated pipe piers 50 . In the illustrated embodiment, eight pile foundations 10 are arranged below the cast-in-place cap 30, and the eight pile foundations 10 are distributed in four rows in two rows; The root prefabricated pipe piers 50 are distributed side by side.

[0037] Please refer to Figure 4 with Figure 5, the prefabricated pipe pier 50 is a prefabricated hollow ci...

Abstract

The invention relates to the technical field of highway bridge construction engineering. The invention discloses a pipe pier and bearing platform connecting structure; socket holes are formed in the upper end of a cast-in-place bearing platform; the lower section of the prefabricated pipe pier is an embedded section which is inserted into the socket hole; a steel end plate fixedly connected with alongitudinal main rib of the prefabricated pipe pier is arranged on the lower end surface of the prefabricated pipe pier; the prefabricated pipe pier is a hollow cylindrical pipe pier, the steel endplate is an annular end plate identical to the end face of the prefabricated pipe pier in shape, pipe pier outer side connecting concrete is poured between the lower end face of the embedded section and the bottom face of the socket holes and between the outer side wall of the embedded section and the inner wall of the socket holes, and a pipe pier inner side core filling concrete is poured into ahollow hole of the embedded section. The invention further discloses a construction method of the pipe pier and bearing platform connecting structure. According to the pipe pier and bearing platformconnecting structure and the construction method, the embedded section of the prefabricated pipe pier is provided with the steel end plate, so that the anchoring length of steel bars in concrete is reduced, the pre-embedded depth and the thickness of the bottom plate of the bearing platform can be reduced, and the overall thickness of the bearing platform is reduced.

Description

technical field [0001] The invention relates to the technical field of highway and bridge construction engineering, in particular to a connection structure between a pipe pier and a cap and a construction method. Background technique [0002] Conventional road bridge column piers are prefabricated by centrifugal technology. Compared with traditional cast-in-place pier columns, prefabricated pipe piers by centrifugal technology have the following advantages: First, the pipe piers can be industrially prefabricated by centrifugal technology, and the quality of components can be guaranteed Second, the centrifugal prefabricated tubular piers can greatly save the amount of concrete without reducing the eccentric compression capacity, shear capacity and seismic capacity of the pier column, which is in line with the construction concept of "prefabricated buildings" and "green roads". [0003] At present, when pipe piers are used for conventional highway bridges, the connections to c...
