Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail.

[0023] The invention provides a method for installing a bridge support, comprising the steps of:

[0024] a. Prepare mortar, which is shrinkage-compensating mortar. The water-binder ratio of the shrinkage-compensating mortar is 0.465, and its strength is not less than 35MPa. The supporting surface of the support is chiseled, and the degree of chiseling meets the regulations on the treatment of construction joints in bridge concrete construction, and the top surface is cleaned. Before the above step a, the reserved holes need to be cleaned, and the top of the pier and abutment should be checked before cleaning. The position, size and depth of the anchor bolt holes shall be thoroughly cleaned after passing the test;

[0025] b. Use a laser locator to position the support;

[0026] c. Install the anchor bolts and t...

Abstract

The invention relates to the technical field of bridge engineering, and discloses a method for installing a bridge support, comprising the steps of: a. preparing mortar; b. using a laser locator to position the support; c. installing anchor bolts and supports; d. Install the formwork; e. Pour mortar; f. Install the anchor bolts of the support and the superstructure. Its operation is simple, and the laser locator is used to set out and position the bridge support to ensure the installation accuracy of the bridge support. At the same time, the installation process is standardized and reasonable, and the support is installed firmly, ensuring the performance and service life of the bridge support.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a method for installing a bridge support. Background technique [0002] With the rapid development of the economy, the construction of roads has also developed by leaps and bounds. The erection of bridges is a very important part of road construction. In bridge erection, the installation of bridge supports determines the overall quality of the entire bridge. . However, the installation process of existing bridge supports is not standardized, which easily causes problems such as inaccurate positioning, which seriously affects the service life of the bridge. Contents of the invention [0003] The purpose of the present invention is to provide a bridge support installation method, which solves the above problems well. It is easy to operate. The laser positioner is used to set out the bridge support to ensure the installation accuracy of the bridge support. At the same ...
