Problems solved by technology

However, due to the variety of geological conditions in our country and the complex and changeable environmental conditions, the ballastless track structure of some subgrade sections of the operating line has offset defects, which affects the ride comfort of the line, resulting in high-speed trains having to run at limited speeds on some road sections

Embodiment 1

[0032] A method for manufacturing a reaction force structure for lateral deviation correction of ballastless track structures in conventional sections of subgrade sections, the method is used for deviation correction operations of ballastless track structures on operating lines, and mainly includes the following steps:

[0033] Step 1: Start the down-the-hole drill to drill the hole. The diameter of the hole is 30mm. It is divided into 4 rows along the line. The holes in each row are arranged in a plum blossom shape. The first and third rows are 4 grouting pipes. The second and third rows are three grouting pipes. The first row of holes is 300mm away from the ballastless track structure. The direction is 45°, oblique to the center of the line, the drilling depth is 3m, and the drilling depth of the straight hole is 2m;

[0034]Step 2: Install the grouting pipe, first install the oblique grouting pipe into the grouting hole, use an air compressor to inflate the grout valve, the...

Embodiment 2

[0039] A method for making a reaction force structure for lateral deviation correction of ballastless track structures in turnout areas, the method is used for deviation correction operations of ballastless track structures in turnout areas of operating lines, and mainly includes the following steps:

[0040] Step 1: Start the down-the-hole drill to drill the hole. The diameter of the hole is 30mm. It is divided into 4 rows of holes along the line. The holes in each row are arranged in a plum blossom shape. The length of each row of holes along the line is the length of the correction section. , the first row of holes is 300mm away from the ballastless track structure, the two rows of holes close to the line are inclined holes, the two rows of holes away from the line are vertical holes, the inclined holes are 40° from the horizontal direction, inclined to the center of the line, and the drilling depth 3m, straight hole drilling depth is 2m;

[0041] Step 2: Install the grouti...

Abstract

The invention discloses a transverse deviation rectification counterforce structure for a ballastless track structure of a roadbed section and a manufacturing method, which are used for solving the problem of transverse deviation of the ballastless track structure of an operation line and realizing the purpose of transverse deviation rectification in an operation-free period by fully utilizing thecharacteristics of the lines. The method comprises the following steps: drilling holes, mounting a grouting pipe, sealing the holes, injecting polyurethane modified cement paste, dismounting an air inlet pipe, mounting stirrups, erecting a mold, and pouring concrete to form a counterforce structure. The counterforce structure has the advantages of being simple in structure, wide in application space range, small in damage to the roadbed structure and large in structural counterforce, and the requirement for transverse deviation rectifying of a ballastless track structure of a roadbed sectionof an operation line can be met.

Description

technical field [0001] The invention belongs to the field of maintenance and repair of ballastless track structures of high-speed railways, can use the skylight time to manufacture the reaction force structure, and the reaction force structure has little disturbance to the roadbed foundation, and provides an effective reaction force for the lateral deviation correction of the ballastless track structure of the roadbed section This method can be applied to various types of ballastless track structures in subgrade sections, and can also be applied to the design of civil construction projects and highway engineering reaction structures. Background technique [0002] In recent years, my country's high-speed railway has developed rapidly, and a "four vertical and four horizontal" high-speed railway network has been initially built. By the end of 2017, the operating high-speed railway mileage reached 25,000 kilometers, and the construction of high-speed railways is moving towards t...
