Abstract

The invention relates to a grouting, rectification and lifting method for a transition section between an embankment and an abutment of a rail. The transition section comprises a roadbed, a base plate, a rail plate, a rail bearing platform, the rail and terminal spines. The method is characterized by comprising the following steps: 1) arranging grouting and rectification braced piles at the terminal spines; 2) performing rectification on the terminal spines; and 3) performing grouting and lifting on a sedimentation part. According to the method, precise control over the lifted height, displacement of translation rectification and displacement error by adopting the bagged grouting method can be realized. The method has the beneficial effects that the construction is fast, the environmental protection property is good, grouting materials are saved, economic efficiency is high, the technology is advanced, the construction method is mature, and the effect is reliable.

Description

technical field [0001] The invention relates to the technical field of maintenance and repair of traffic infrastructure, in particular to a new method for grouting lifting and rectifying the transition section of a ballastless track of a high-speed railway. Background technique [0002] With the continuous increase of train speed, the requirements for track smoothness are becoming more and more stringent. Due to the very different nature of embankment and bridge engineering, serious track irregularities are likely to occur at the junction of roads and bridges. The large dynamic effect not only reduces the running stability of the vehicle, but also affects the safe operation of the train. At the same time, this dynamic effect will increase the uneven settlement and damage the structure of the transition section. Therefore, it is particularly important to control the settlement deformation of the road-bridge transition section. At present, the operating mileage of my country...
