Abstract

The invention discloses a system and method for high-speed railway subgrade settlement restoration. The system comprises at least eight lifting components, at least eight hydraulic lifting devices, a hydraulic distribution device, an automatic control system and a grouting device, wherein the at least eight lifting components are arranged at preset lifting points on a base plate, and every lifting component comprises a connecting part and a lifting part; every hydraulic lifting device is arranged between a high-speed railway subgrade and the lifting part of the lifting component; the hydraulic distribution device is connected with every hydraulic lifting device through hydraulic pipelines; the automatic control system controls the hydraulic distribution device to provide preset hydraulic pressure for every hydraulic lifting device so as to lift the base plate to a preset height of the high-speed railway subgrade; and the grouting device pours slurry in gaps formed between the base plate and the high-speed railway subgrade through slurry pipelines so as to support the base plate after the slurry is solidified. The invention further provides a method for track plate and base plate integrated lifting type high-speed railway subgrade settlement restoration.

Description

technical field

[0001] The invention relates to a railway embankment repair system and method, in particular to a high-speed railway embankment repair system and method. Background technique

[0002] After years of high-speed railway construction, my country has built the world's largest high-speed railway network. Slab ballastless track is generally used in high-speed railways, which is a kind of track composed of cast-in-place cement concrete support layer, cement emulsified asphalt mortar layer, prefabricated concrete track slab, inter-slab connectors, rails and fasteners on the subgrade. New track structure. Compared with the traditional ballasted track, since the ballastless track cancels sleepers and ballast beds, and uses prefabricated reinforced concrete slabs to directly support the rails, it has the following advantages: good stability and smoothness; low building height and light weight, which can reduce bridge The second phase load and reduce the tunnel clearan...
