Method for renovating subgrade subsidence of operating high-speed rail
The invention provides a method for renovating subgrade subsidence of an operating high-speed rail. The method comprises the steps that 1, grouting holes are formed in a subgrade of the high-speed rail; and 2, holes are drilled in the positions of the arranged grouting holes to form grouting holes, and grouting is carried out in the grouting holes, wherein track parameter changes are monitored inthe grouting process. The method is used for carrying out construction on an existing railway so as to renovate roadbed sinking of the operating high-speed rail, meanwhile, the method can carry out construction on site in real time, damage to the roadbed is small, and the engineering cost is low; and according to the method, through grouting, slurry extrudes away moisture and gas in the soil bodyin the modes of filling, permeation, compaction, splitting and the like, original gaps or cracks in the soil body are filled, loose soil particles are bonded together, the compactness of the soil bodyis improved, the slurry and the soil body are bonded into a whole, and a combination body with a novel structure, high strength and good waterproof performance and chemical performance is formed, sothat the anti-sedimentation performance of the roadbed is greatly improved.
本发明提出了一种整治运营高铁的路基下沉的方法，包括步骤一，在高铁的路基上布设注浆孔；步骤二，在布设的注浆孔位置处钻孔以形成注浆孔，并向所述注浆孔内进行灌浆，其中，在灌浆过程中监控轨道参数变化，该方法针对既有铁路进行施工，以整治运营高铁的路基下沉，同时，该方法能够在现场实时进行施工，对路基损坏小，工程造价低，另外，该方法通过灌浆使得浆液以填充、渗透、挤密和劈裂等方式，将土体中的水分和气体挤走，充填土体中原有的空隙或裂隙，使松散的土颗粒黏结在一起，提高土体密实度，并与土体胶结成一个整体，形成了一个结构新、强度大、防水性能和化学性能好的结合体，从而大大地提高了路基抗沉降的性能。
