Bridge incremental launching construction connecting traction system and construction method

Abstract

The invention relates to the field of engineering, in particular to a bridge incremental launching construction connecting traction system and a construction method. The system comprises a counterforce frame, a steel platform and jacks, wherein the two hydraulic clustered jacks are arranged on the steel platform, the sides of the two jacks are connected to a steel strand and abut against the counterforce frame, an anchoring box is connected to one side of the steel strand, and the anchoring box is arranged on an assembled beam section. The connecting traction system and the construction method are used for large-span steel arch bridge incremental launching construction. The system replaces an original full support method, a cable hoisting method, a rotating body construction method and the like through which construction plants need to be arranged on both shores, a large number of large supports and mechanical devices are adopted, the construction risk is high, the operation environment is poor, the efficiency is low, and the cost is high; the construction plant is saved, the production efficiency is improved, the construction cost is greatly lowered, the project quality is easily ensured, the benefit is remarkable, and the effect is good.

Description

technical field [0001] The invention relates to the field of engineering, in particular to a continuous traction system and a construction method for bridge pushing construction. Background technique [0002] In recent years, steel arch bridges of various shapes are thriving and blooming everywhere in my country because of their beautiful appearance and reasonable force. The construction technology of steel arch bridge is also a practical problem before researchers and engineers. In the past, the full house support method, cable hoisting method, and swivel construction method all required setting up construction sites on both sides of the bank, and invested a large amount of large supports and mechanical equipment. The construction risk was high, the working environment was poor, the efficiency was low, and the cost was high. Therefore, it is an urgent technical problem to explore a safe, reliable, high-quality and efficient construction method for the installation of long-s...
