Simple and adjustable track support system and construction method thereof

Abstract

The invention discloses a simple and adjustable track support system and a construction method thereof. The adjustable support system comprises a set of adjusting devices located under a support layer, and a support column between the adjusting devices and a foundation; a support plate is connected between the upper portions of the adjusting devices and the support layer; a base plate is connectedbetween the lower portions of the adjusting devices and the support column; the support column comprises four corner posts and a horizontal connecting plate between the corner posts; and the supportcolumn and the foundation are connected with a cast-in-place fixed foundation through a fixing plate. During construction, through the adjusting devices and the base plate, the requirements of phasedor graded height adjustment of track lowering or upper arch deformation are met, by arranging a rigid plate and an elastic plate, the force area is enlarged, the effect that the support layer is not damaged during construction is ensured, through the fixing plate and the cast-in-place fixed foundation, the effect that upper load is dispersed into the foundation is ensured, the system can support during underground excavation and padding replacement without dismounting track boards of the track at all stages, the height of the support system is adjustable, construction is convenient, time is saved, and the cost can be reduced.

Description

technical field [0001] The invention belongs to the field of track construction, in particular to a simple and adjustable track support system and a construction method thereof. Background technique [0002] In the track construction, due to the complex geological conditions of the route that the railway passes, and the change of the upper arch caused by external factors such as rainfall, temperature and dynamic load during the operation of the track, the track will be carried out under the original design. Height adjustment, and for adjusting the track elevation, it is necessary to excavate the subgrade bed filler at the lower part of the track support layer, and set up a support device at the same time. Generally, a one-time temporary support is used, but the structure of the temporary support is weak, and it is mostly used for closed road sections. Temporary use, on the premise of large-area or long lines and the premise of ensuring the upper part of the vehicle, its impl...
