A method for building concrete bridge towers

Abstract

The invention relates to the technical field of bridge construction methods, in particular to a method for building concrete bridge towers. After the concrete construction of the bridge tower of the Nth section is completed, the inner mold support is climbed vertically to the construction position of the bridge tower of the N+1th section, and the steel cage of the N+1th section is made and hoisted to the inner mold support as a whole , adjust the position of the reinforcement cage of the N+1 segment and connect it with the steel bar of the N segment bridge tower, and drive the external formwork support to climb vertically to the construction position of the N+1 segment bridge tower. The bridge tower of section N is demoulded, and the removed formwork is hoisted to the construction site of bridge tower of section N+1 for assembly and installation, the concrete of bridge tower of section N is maintained, and the bridge tower of section N+1 is poured. Vibrate the concrete of the N+1 section of the bridge tower until the concrete pouring of the N+1 section of the bridge tower is completed, repeat the above steps, and pour section by section until the construction of the bridge tower is completed. The tower building method of the present invention has clear flow, high tower building efficiency and great popularization value.

Description

technical field [0001] The invention relates to the technical field of bridge construction methods, in particular to a method for building concrete bridge towers. Background technique [0002] Conventional bridge tower construction adopts the methods of top formwork, lifting formwork and hydraulic climbing formwork. The main problems in construction are as follows: [0003] 1) Construction efficiency is low: centralized control is impossible, installation and erection of internal and external formwork brackets is difficult, construction is difficult, time-consuming, unified control and coordination cannot be carried out, and the construction process is relatively chaotic and disorderly. [0004] 2) The construction quality is not high: the positioning accuracy of the steel bars is low, the pass rate of the protective layer is not high; the layout of the bridge tower concrete maintenance structure is difficult, the maintenance conditions are poor, the maintenance effect is po...

AI Technical Summary

Problems solved by technology

[0009] The inner mold bracket and the outer mold bracket of the present invention have the function of automatic climbing, the inner mold bracket has the functions of steel cage position adjustment and hoisting, and concrete vibration construction, and the outer mold bracket has the functions of template lifting, concrete curing, and concrete distribution. The functions of material distribution, maintenance, vibration, hoisting and climbing form a set of orderly, efficient and fast bridge tower building methods, which solve the problems of slow construction, difficult maintenance and low precision existing in existing tower building technologies, and The construction process of the present invention has the conditions of intelligent centralized control, and is suitable for wide-scale popularization and use
