Problems solved by technology

As the construction of temporary tied arch bridges develops in the direction of large spans and low energy consumption, temporary tie rods are mostly made of permanent tie rod materials. During the installation process of temporary tie rods by dragging across the river, the surface of the temporary tie rods will be separated from the Scratches on the construction ship, abutment, ground and the openings of the pre-buried tunnels will cause damage to the surface of the temporary tie rods, which will directly shorten the service life of the tie rod arch bridge; in addition, the temporary tie rods have large tension deflection and are easy to There are a series of technical problems such as collision with the installation of lattice beams, and there are hidden dangers in construction safety

Abstract

The invention discloses a temporary tie bar stretch-across installation method. The method includes the following steps of mechanism supply, bag lifting, anti-scratching measure taking, large-span installation and fixing. The temporary tie bar stretch-across installation method can reduce the damage to a surface layer of a temporary tie bar in the installation process.

Description

【Technical field】 [0001] The invention relates to the technical field of bridge construction, in particular to a method for installing a temporary tie bar across the bridge. 【Background technique】 [0002] Concrete-filled steel tube tied arch bridge has a large market among medium-span bridges because of its beautiful appearance, good economy and short construction period. When building a tied arch bridge, in order to make the arch end support not produce horizontal thrust and become a thrustless arch, it is necessary to install temporary tie rods between the abutments. The installation of the temporary tie rod needs to cross the river surface. In the prior art, the temporary tie rod is rolled up in one river bank, and a hoist is placed on the other river bank. One end of the temporary tie rod is connected by the hoist through a traction rope, and the hoist is started. The temporary tie rod Pulled out from a river bank under the traction of the traction rope, the temporary ...
