Intelligent continuous transverse moving construction method for railway box girder adjacent to existing high-speed rail
The invention relates to the technical field of bridge construction, in particular to an intelligent continuous transverse moving construction method for a railway box girder adjacent to an existing high-speed rail. The railway box girder adopts an intelligent continuous pushing system to carry out transverse moving operation, and the intelligent continuous pushing system comprises a control system, a hydraulic pump station and a continuous jack; the continuous jacks are slidably arranged on transverse slide ways on the two sides of the bottom of the railway box girder and used for continuously pushing the transverse sliding shoes to transversely move. The hydraulic pump station is used for carrying out stepless speed regulation on the continuous jack; the intelligent continuous transverse moving construction method comprises the steps that S1, transverse moving operation is conducted, specifically, continuous jacks on transverse sliding ways on the two sides of the bottom of a railway box girder are started at the same time to conduct pushing operation; the control system synchronously collects and compares displacement data of the continuous jacks and controls the hydraulic pump station to carry out real-time speed compensation on the continuous jacks; and S4, beam falling operation is carried out. Through the arrangement, synchronous pushing between the continuous jacks on the two sides of the bottom of the railway box girder can be achieved.
本申请涉及桥梁施工技术领域，特别涉及一种邻近既有高铁的铁路箱梁智能连续横移施工方法。铁路箱梁采用智能连续顶推系统进行横移作业，智能连续顶推系统包括控制系统、液压泵站、连续千斤顶；连续千斤顶滑动设置在铁路箱梁底部两侧的横向滑道上，用于连续顶推横向滑靴横向移动；液压泵站用于对连续千斤顶进行无级调速；智能连续横移施工方法包括：步骤S1，横移作业：同时启动铁路箱梁底部两侧的横向滑道上的连续千斤顶进行顶推作业；控制系统同步采集并对比连续千斤顶的位移数据，并控制液压泵站对连续千斤顶进行实时的速度补偿；步骤S4，落梁作业。通过上述设置，可实现铁路箱梁底部两侧连续千斤顶间的同步顶推。
