Problems solved by technology
[0003] There are several deficiencies in the existing maintenance methods for the shoulder disease: 1. Replacing the gasket cannot prevent the disease from continuing to develop, and the gasket is easy to be crushed or squeezed, posing a certain safety hazard
The maintenance time for solving the problem is short, and it is necessary to repeatedly arrange personnel for maintenance, which consumes a lot of labor
2. The workload of replacing sleepers is large, and the stability of the ballast bed is damaged. The construction conditions are relatively high. After construction, the work of restoring the stability of the ballast bed is required, and the cost consumption is relatively high.
3. The construction of pillow replacement is basically manual work, and it needs to be operated at the skylight point, so the maintenance efficiency is low
4. Pillow replacement construction, especially on bridges and in tunnels, is subject to site constraints and poses major safety hazards
The above deficiencies have caused greater construction difficulty and safety pressure to the maintenance of public works

Embodiment Construction
[0014] In order to make the above objects, features and advantages of the present invention more obvious and comprehensible, the present invention will be further described in detail below in conjunction with specific embodiments.
[0015] Step 1. According to the requirements of the "Railway Works Safety Rules", select the shoulders that are seriously damaged and need to be repaired, mark the ends of the sleepers with a stone pen, and remove the fasteners at the shoulders.
[0016] Step 2. Clean the surface of the damaged shoulder, and remove the floating slurry around the embedded bolts with a wire brush or chisel to ensure that the lower slope and bottom surface of the nylon backing plate of the shoulder are smooth, and then remove the oil stains with water and a wire brush .
[0017] Step 3, the sleeper shoulder repair template (attached image 3 ) placed at the shoulder position, adjust the formwork and the shoulder as closely as possible, and remove the formwork after m...

The invention discloses a sleeper shoulder repairing technology, and belongs to a safety guarantee technology of a railway engineering system. The method is characterized by comprising the following steps: firstly, dismounting a shoulder fastener, mounting a template for sleeper shoulder repair, taking down the template after marking, then cutting, chiseling and roughening the damaged shoulder, mounting the template again, pouring a repair material, dismounting the template after maintenance is finished, and recovering the sleeper for use after 3-7 days. The method successfully solves the problems of time and labor consumption in maintenance, high maintenance cost, low maintenance efficiency, poor effect, high construction safety pressure and the like in the existing sleeper shoulder disease treatment measures. According to the method, the maintenance cost is saved by 70%-80%, the maintenance efficiency is improved by more than 10 times, and the safety during maintenance operation is remarkably improved, so that good economic and social benefits are obtained.
Description
technical field [0001] The invention relates to a safety guarantee technology of a railway construction system, in particular to the treatment of railway concrete sleeper diseases. Background technique [0002] For ballasted railways, especially ordinary-speed railways in mountainous areas, the disease of sleeper shoulders is common and serious, which has caused great safety hazards to railway operations and is one of the main diseases in line maintenance. The maintenance measures for such diseases mainly include: for sleepers with light diseases, replace thick gaskets or add rubber gaskets; for serious diseases, replace sleepers with new ones. At present, no one at home and abroad has conducted in-depth research on the maintenance technology and maintenance materials for this disease. [0003] There are several deficiencies in the existing maintenance methods of the shoulder disease: 1. Replacing the gasket cannot prevent the disease from continuing to develop, and the gas...
