Problems solved by technology
If the subgrade has excessive arching or settlement, exceeding the adjustment range of the fastener, only speed limit operation can be adopted, which will affect the normal operation of the railway
Excessive deformation of the subgrade also causes instability of the subgrade structure, which brings safety hazards to the operation of high-speed railways

The invention provides a supporting device. The supporting device comprises a supporting base and adjustable supporting parts evenly arranged on the supporting base. The adjustable supporting part comprises a sleeve and a lead screw arranged in the sleeve, a nut is arranged at the top of the sleeve, and the lead screw is sleeved with the nut. The invention further provides a using method of the supporting device. The using method comprises the steps that firstly, the supporting device is evenly arranged at the bottom of a foundation pit; 2, a hydraulic jack is placed on a supporting base of the supporting device, and the height of the rail is adjusted through jacking and descending of the hydraulic jack according to the comparison result of the original designed elevation of the rail and the actual elevation of the field; 3, the supporting device is adjusted to support the rail, and the supporting device is fixed; and 4, after the hydraulic jack is taken out, backfill pouring is conducted. According to the supporting device and the using method thereof, the supporting device can be suitable for a narrow construction space, and good operability and safety are achieved.
Description
technical field [0001] The invention relates to the technical field of high-speed railway subgrade maintenance equipment, in particular to a support device for ballastless track structure maintenance and a method for using the same. Background technique [0002] In recent years, with the rapid development of high-speed railways, my country has built large-scale high-speed railways, which has brought great convenience to people's travel. However, during the operation of high-speed railways, there will be some disease problems in the railway subgrade. These diseases are mainly manifested as the arching or settlement of the subgrade, resulting in the unevenness of the ballastless track. Minor deformation can be solved by adjusting the thickness of the track fastener. If the subgrade has excessive arching or settlement, exceeding the adjustment range of the fastener, only speed-limited operation can be adopted, thereby affecting the normal operation of the railway. The excess...
