Description

Technical Field

[0001] The utility model relates to the technical field of railway roadbed repair, and more specifically, to a high-speed railway roadbed settlement repair operation device. Background Art

[0002] High-speed railways are a key symbol of railway modernization and a complex system engineering project. Since the opening of my country's first high-speed railway, the Beijing-Tianjin Intercity Railway, in 2008, the total operating mileage of high-speed railways has reached approximately 42,000 km. It is projected that by 2025, the total length of high-speed railways with speeds of 200 km / h and above will exceed 50,000 km, accounting for more than half of the world's total high-speed railway mileage. The advantages of high-speed railways, such as large capacity, high speed, and rapidity, have greatly facilitated people's travel. However, high-speed railways can only ensure the safety, stability, and comfort of high-speed, uninterrupted train operation if their lines meet high standards of smoothness, stability, and precision.

[0003] After several years of operation, many high-speed rail lines in my country have experienced subsidence in the roadbed of some lines, causing the upper base plate, track plate and rail surface to sink. For some sections with severe settlement (more than 10 cm), the adjustment range of the rail fasteners has reached its limit and cannot meet the current track elevation requirements. To ensure driving safety, speed limits have to be implemented on some sections, seriously affecting the operation quality of the line. To completely solve the problem, the high-speed rail base plate must be raised to the specified height, and then the cavity must be filled with filler to eliminate the settlement and restore the track to its original elevation.

[0004] After searching, the Chinese patent with application number CN201920133439.X discloses a high-speed railway subgrade settlement repair system. This utility model does not occupy the railway driving space and does not affect the normal railway operation. It can not only reinforce the gap between the base plate and the roadbed, but also reinforce the roadbed surface to tens of meters below the roadbed. The roadbed is constructed through the skylight points on the track during the driving interval, effectively ensuring the smooth operation of the train.

[0005] When the above-mentioned high-speed railway subgrade settlement repair system is actually used, due to the subgrade settlement, the space required for grouting is narrow, which may cause the filling material to not fully enter or be unevenly distributed, resulting in unsatisfactory repair results and increasing the difficulty and complexity of grouting.
