Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0024] The embodiment of the present invention provides a continuous drag-and-drag track-laying construction process for a 25-meter standard rail. After the sleeper, ballast transport paving, cloth pillow, and sulfur anchorage are completed, the rail dragging construction operation is carried out; the operation process is as follows: Figure 1-3 As shown, rail material unloading→laying rollers→horizontal slide rail bracket installation and towing rail preparation→rail towing construction→removal of rollers and horizontal slide rail brackets→fastener installation→rail unloading and rail connection si...

The invention discloses a construction technology of continuous dragging type rail laying of 25-meter standard rails. After the completion of sleeper construction, ballast transportation paving, sleeper laying and sulfur anchoring, the construction of rail dragging is carried out. The operation processes comprise the steps of rail material unloading, roller laying, transverse slide rail bracket installation and rail dragging preparation, rail dragging construction, removal of roller and slide rail bracket, fastener installation, 500-meter antedisplacement of rail unloading and connecting locations and laying of a second group of rails, and finally, other aspects of rail construction work is carried out. According to the scheme, one roller is placed every 10 meters in the step 2. Accordingto the construction technology of continuous dragging type rail laying of the 25-meter standard rails, the machinery investment can be reduced, and rail laying base construction is saved; and the efficiency is higher than that of manual rail laying, rail transportation is not limited by construction roads, the labor intensity is reduced, and the construction efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of railway track engineering construction, and in particular relates to a continuous drag-and-drag track-laying construction process for a 25-meter standard rail. Background technique [0002] The existing 25m standard gauge track laying methods are: [0003] 1. Track laying by track laying machine: It is necessary to build a track laying base, and the investment in machinery is large, and the cost of mechanical transfer is high. [0004] 2. Manual track laying: The efficiency of manual track laying is low, and the rails need to be transported to the construction site in sections by car, which is limited by the construction access road. Contents of the invention [0005] In view of this, the main purpose of the present invention is to provide a continuous drag-and-drag track-laying construction process of a 25-meter standard rail. [0006] In order to achieve the above object, technical solution of the p...
