Abstract

The invention discloses a three-point supporting method for pipe joint prefabricating and pushing construction according to the factory method, and particularly relates to a three-point supporting method for achieving smooth pushing on a pipe joint through a three-point supporting hydraulic system. The three-point supporting method comprises a master control circuit for controlling the three-point supporting hydraulic system to jack and push a pipe joint section of the pipe joint; when the pipe joint section is pushed to a proper position, the three-point supporting hydraulic system is demounted; after pre-casting on a next pipe joint section is finished, the three-point supporting hydraulic system is respectively connected with the supporting jacks for the two pipe joint sections; the master control circuit controls the three-point supporting hydraulic system to jack and push the two pipe joint sections; after the two pipe joint sections are pushed to proper positions, the three-point supporting hydraulic system is demounted; after pre-casting on a next pipe joint section is finished, the three-point supporting hydraulic system is respectively connected with the supporting jacks for the three pipe joint sections; the rest can be done in the same manner until pushing on all the pipe joint sections forming the pipe joint is finished.

Description

technical field

[0001] The invention relates to a three-point support method for prefabricated pipe joint pushing construction by factory method, in particular to a three-point support method for realizing stable pipe joint pushing through a three-point support hydraulic system. Background technique

[0002] At present, the prefabrication of super-large immersed tubes basically adopts two construction ideas: the factory method and the dry dock method. Because the dry dock method has a long turnover period for construction equipment and cannot meet the requirements of the construction period, the factory method is often used. The basic idea of ​​this method is Assembly line production and construction, improve efficiency and shorten construction period. For the super-large prefabricated immersed tubes constructed by the factory method in the world, the jacking operation basically adopts two ideas: centralized jacking and multi-point decentralized synchronous jacking; the cent...
