[0002] After the long-sleeper embedded integral ballast is cast and formed, the surface of the sleeper must be higher than the cast-in-place concrete. During pouring, the concrete should be distributed to the center and both sides of the corresponding rails. When the pumping concrete process is used for pouring operations, in order to prevent concrete accumulation from causing the concrete flow distance to be too long, affecting its uniformity and thus affecting the uniformity of the final strength, the pump pipe outlet needs to move intermittently.
[0003] When the discharge port of the mobile pump pipe is moved, it is very easy to contaminate the rails and sleepers. After the sleepers or rails are contaminated, they need to be thoroughly cleaned with a brush dipped in water before the concrete solidifies. However, the cleaning water flowing into the ballast concrete will change the mix ratio of the concrete, which is prone to quality problems such as reduced strength and surface peeling. In order to avoid the quality problems caused by this, a tunnel concrete spreading device is proposed to solve the above problems. Utility Model Content
