Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] refer to figure 1 , the embodiment of the present application provides a method for remediating track settlement diseases, comprising the following steps: S1, determining the settlement amount of the diseased section of the track 10; S2, installing monitoring elements 11a at both lateral ends of the track plate 11 to monitor the track 10 The amount of lift, wherein, the monitoring element 11a is electrically connected to the PLC control system; S3, from the road shoulders 20 on both sides of the track 10 corresponding to the diseased section to the subgrade below the track 10, respectively, and inserting multiple rows of grouting pipes 20a; S4, along the The rail 10 is grouted sequentially from outside to inside in the grouting pipe 20a to lift the rail 10 in stages.

The invention provides a rail settlement disease treatment method. The rail settlement disease treatment method comprises the following steps that the settlement amount of a disease section of a railis determined; monitoring elements are installed at the two transverse ends of a track plate to monitor the lifting amount of the track, and the monitoring elements are electrically connected with a PLC control system; multiple rows of grouting pipes are obliquely arranged towards the roadbed below the track from road shoulders on the two sides of the track corresponding to the disease section; and grouting is sequentially conducted in the grouting pipes from outside to inside in the transverse direction of the track so as to lift the track in a staged mode. According to the renovation method,the lifting amount of the track in the grouting process is monitored in real time through the monitoring elements and the PLC control system electrically connected with the monitoring elements, and excessive lifting of the track is avoided; and the same settlement section is subjected to multi-stage grouting, firstly, a grouting curtain is formed on the outer side of the settlement section, then,grouting is sequentially conducted from outside to inside in the transverse direction of the track, grouting of the later stage is supplement to grouting of the previous stage, the lifting resilienceamount of the track is reduced, and the purposes of reinforcing the stratum and improving settlement diseases are achieved.
Description
technical field [0001] The invention relates to the technical field of rail transit regulation, in particular to a method for regulating rail subsidence diseases. Background technique [0002] After a period of operation of the high-speed railway or rail transit that has been in operation, under the influence of internal and external factors, local foundation bearing capacity will be insufficient, resulting in uneven settlement diseases, which will affect operational safety. In particular, the ballastless track line has very high requirements on linear accuracy. It can be fine-tuned to improve settlement through fastener backing plates, but the adjustment range is limited, and the disease cannot be fundamentally eliminated. [0003] When using omnidirectional high-pressure jetting technology (MJS for short) to reinforce the roadbed, the cost is high, the construction machinery is complex and the construction period is long, and the impact on operation is long. Grouting tech...
