Background
The high-speed railway is an important mark of railway modernization and is complex system engineering. Since the first high-speed railway, namely the Jingjin intercity railway, is opened in 2008 in China, the operating mileage of the current high-speed railway reaches about 7000km, the high-speed railway with the speed of 200km or more is expected to exceed 1.8 ten thousand meters in 2020, and the operating mileage of the high-speed railway accounts for more than half of the total mileage of the high-speed railways in the world, the high-speed railway greatly facilitates the travel of people due to the advantages of large traffic, high speed, rapidness and the like, and the high-speed railway can ensure the safety, stability and comfort of high-speed and uninterrupted operation of trains only if the lines meet the requirements of high smoothness, high stability and high precision.
After a plurality of high-speed railway lines in China are opened and operated for years, subgrades of partial lines are settled, so that the surfaces of upper base plates, track plates and steel rails are lowered, and for certain road sections (more than 10cm) with serious settlement, the adjustment range of steel rail fasteners reaches the limit and cannot meet the requirement of the existing rail elevation. In order to ensure the driving safety, speed-limiting measures have to be taken on individual road sections, and the operation quality of the line is seriously influenced. To thoroughly solve the problem, the high-speed rail base plate is lifted to a specified height, then the cavity is filled with fillers, settlement is eliminated, and the original elevation of the rail is restored.
However, at present, the defect of high construction strength exists in the process of lifting the base plate of the high-speed rail and recovering the base plate to the current rail elevation, and the existing railway generally needs to be sealed and constructed to limit the passing of railway vehicles, and the construction period is long.
For example, in the grouting lifting fast restoration technology for a ballastless track disclosed in chinese patent application No. 201310382596.1, the restoration technology includes grouting materials, equipment tools, and related construction processes and steps, the restoration technology specifically adopts high-pressure grouting equipment, and under the conditions of certain grouting equipment process parameters such as grouting pressure, temperature, flow and the like, a fast-setting and fast-hardening grouting material is injected into graded broken stones at the lower part of a ballastless track bed through a grouting pipe pre-installed in a grouting hole, and in the grouting process, the elevation of the track structure is monitored in real time by using precision measurement devices such as an electronic level gauge and the like, so as to realize the precise lifting of the upper structure of the ballastless track. However, the following disadvantages or shortcomings still exist in the present invention: (1) only filling and reinforcing gaps of graded broken stones at the lower part of a ballastless track bed serving as a foundation bed, and not reinforcing the gaps between a base plate and the foundation bed; (2) no specific structural components of the prosthetic device are disclosed.
As also disclosed in chinese patent application No. 201410410235.8, a grouting lifting rapid repair method for a settled ballastless track includes grouting materials, equipment tools and a construction process, specifically, after the ballastless track lifting amount is determined, a high-pressure grouting equipment is used, under a certain grouting pressure, a rapid-setting and rapid-hardening grouting material is injected into a grouting bag which is horizontally placed in advance under a ballastless track base and in a graded crushed stone surface layer through a grouting pipe in a certain sequence, in the grouting process, an electronic level precision measuring device is used to monitor the structural elevation change of an upper track in real time, the grouting lifting is stopped when the structural elevation is close to or reaches a design elevation, then the high-fluidity rapid-setting and rapid-hardening grouting material is directly injected and filled into a gap between the lifted base and the graded crushed stone layer, the grouting material is rapidly filled and cured, the lifted base and the graded crushed stone layer are bonded into a whole, the ballastless track can be accurately lifted and firmly positioned. However, the following disadvantages or shortcomings still exist in the present invention: (1) the grouting bag needs to be placed for grouting, the process is complex, and the construction cost is high; (2) the construction process is complex, and the time of normal running of the railway is occupied; (3) no specific structural components of the prosthetic device are disclosed.
Therefore, the high railway foundation settlement repairing device which does not occupy the railway running space, can reinforce the gap between the base plate and the roadbed and can reinforce the surface of the roadbed to a depth of tens of meters below the roadbed is a problem which is urgently needed to be solved in the industry.
