Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings.
[0031] A construction method for disease control of ballast bed and tunnel bottom, the steps are:
[0032] (1) Firstly, fast-setting materials are used to build drainage channels in the side ditch 12 between the integral ballast bed and the ditch 11, and the water in the damaged ditch is drained through the channel to ensure that the diseased area is dry;
[0033] (2) Insert steel plates 10 at intervals of 5-10cm in the opening and closing area of the track bed plate and the bottom plate. The length of the steel plate 10 is divided into 0.6m-1.2m, the width is 0.1m, and the thickness is 6mm-12mm;
[0034] (3) Drill anchor holes in the side ditch between the ballast bed slab and the ditch on both sides, and drill another anchor hole in the middle of the ballast bed slab between the two anchor holes, so that the three anchor holes The rod holes are on the same line pe...
