Cast-in-place tower of cable-stayed bridge and construction method of cast-in-place tower

Abstract

The invention relates to a cast-in-place tower of a cable-stayed bridge. The cast-in-place tower of the cable-stayed bridge comprises an upper tower straining beam supporting mold system, an upper tower supporting mold system, a lower tower supporting mold system and a cast-in-place tower construction tower crane system, wherein the upper tower straining beam supporting mold system comprises a supporting mold system construction platform, a longitudinal straining beam supporting system and a hanging type concrete pouring platform, the upper tower supporting mold system comprises a fast speed sliding type transferring system, a template fixing adjusting system and a stiff skeleton positioning and connecting device, the lower tower supporting mold system comprises a scaffold system integraltype hoop pile cap fixing system, a template fixing adjusting system fixed to a scaffold and a lower tower template system, and the cast-in-place tower construction tower crane system comprises an integral pre-buried tower crane foundation, a tower attached type hoop device and a tower crane. The cast-in-place tower has the beneficial effects that the tower crane foundation adopts the prefabricated integral type pre-buried tower crane foundation, the prefabricated foundation is placed in a space reserved in a pile cap and is fixed, the construction is simple, and the technical benefit is remarkable.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a cast-in-place tower column of a cable-stayed bridge and a construction method thereof. Background technique [0002] The cable-stayed bridge is one of the most popular types of large-diameter bridges in my country. So far, there are more than 30 cable-stayed bridges completed or under construction, among which the number of long-span concrete cable-stayed bridges ranks first in the world. A cable-stayed bridge, also known as a cable-stayed bridge, is a bridge in which the main girder is pulled on the bridge pylon by many cables. It is a structural system composed of tower columns under pressure, cables under tension and beams mainly under pressure. It can be regarded as a continuous beam supported by multiple collapses elastically supported by stay cables instead of piers. As a cable system, the cable-stayed bridge has a larger spanning capacity than the girder br...

Problems solved by technology

The construction of the traditional cable-stayed bridge tower column formwork system is more troublesome, especially the tie beam formwork system has always been a difficult point, and the construction is the most cumbersome, mainly reflected in the slow speed of formwork assembly and construction, and it is difficult to find a good formwork system. Strength points, especially concrete pouring and vibration are difficult, and the construction is slow. It takes a lot of manpower and material resources to complete the construction of the cable-stayed bridge tower column.
