Embodiment

[0032] The present invention will be described in further detail below in conjunction with the embodiments shown in the accompanying drawings.

[0033] like Figure 1-4 As shown, the applicable object of the present invention is the ballastless track of the high-speed railway, including the subgrade reinforcement area, the cushion layer at the top of the reinforcement area, the subgrade body, the track slab, the rail, the uneven loading area and the subgrade offset area.

[0034] The method includes the following steps:

[0035] Step 1: When the high-speed railway embankment adjacent to the existing structure is subjected to asymmetric surcharge and lateral displacement occurs to the other side of the embankment, multiple rows of stress relief holes are arranged in the surcharge area, and the bottom of each stress relief hole enters the holding area as much as possible. Stress layer, and fill the hole with a material that can prevent the stress release hole from collapsing an...

Abstract

The invention relates to a deviation correcting structure and deviation correcting method for asymmetrical earth fill load deviation of a high-speed railway roadbed. The structure and the method are used for performing unloading deviation correction on the high-speed railway roadbed deviation near the existing structure in a soft soil area. The structure consists of an asymmetrical earth fill load region, a roadbed structure region, a roadbed deviation region and an existing structure region which are in sequential distribution in parallel, wherein high-speed railway steel rails are laid on the surface of the roadbed structure region; at least one stress release hole belt and a plurality of rows of chemical churning piles are arranged in a connecting position of the asymmetrical earth fill load region and the roadbed structure region in the extending direction of the high-speed railway steel rail; and an unloading slope is also arranged on the surface of the asymmetrical earth fill load region. Compared with the prior art, the structure and method have the advantages that the control is easy; the operation is flexible; safety and controllability are realized; and the application prospects are wide, and the like.

Description

technical field [0001] The invention relates to the technical field of high-speed railway embankment disease treatment, in particular to a deviation correction structure and a deviation correction method for a high-speed railway subgrade subjected to asymmetric surcharge deviation. Background technique [0002] At present, the pattern of "four vertical and four horizontal" passenger dedicated lines in my country has basically been established. At the same time, with the construction of intercity high-speed railway passenger transport systems in economically developed and densely populated areas such as the Bohai Sea Rim, the Yangtze River Delta, the Pearl River Delta, and Chengdu-Chongqing, high-speed railways have become the link between cities in the regional urban system by virtue of their excellent technical and economic characteristics. One of the most convenient transportation methods. However, with the increasing passenger and freight volume of my country's high-spee...
