Layered pouring and distributing machine and lining trolley comprising same

Abstract

The invention provides a layered pouring and distributing machine. The layered pouring and distributing machine comprises a trolley, a pipeline system and a telescopic rotating device. The trolley includes a car body and a walking part. The pipeline system includes a feed pipe group, a discharge pipe group, a connecting pipe group and a grouting opening fixing sleeve. The connecting pipe group isarranged on the car body through the telescopic rotating device. According to the technical scheme, the layered pouring and distributing machine has the effects that the whole structure is tidy; the combined design of the telescopic rotating device and the connecting pipe group can arbitrarily change the position of the outlet end of the connecting pipe group, and concrete grouting operation is facilitated; and grouting opening fixing pipes are arranged in layers to realize the layered grouting of a tunnel, the interruption time of pumping concrete is short, the pipe blockage is avoided, and the grouting quality is improved. The invention further discloses a lining trolley comprising the layered pouring and distributing machine. The lining trolley is applied to enable the distributing machine to distribute the concrete pumped by a conveying pump to pipelines, layered pouring at different longitudinal positions is realized, and the pouring efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of lining, in particular to a layered pouring distributing machine and a lining trolley including the distributing machine. Background technique [0002] In the secondary lining process, the commonly used method of concrete grouting is: using a distribution device such as application number 201220331471.7 for grouting. This device specifically includes a reversing pipe for conveying concrete and various parts connected to the trolley. There are a plurality of concrete introduction chutes at the mold entry window, and a reversing pipe is arranged above the plurality of concrete introduction chutes, and the outlet end of the reversing pipe can be switched among the plurality of concrete introduction chutes. [0003] This method has the following disadvantages: [0004] 1. There are many gate valves, the operation is cumbersome, and a lot of staff (usually 6-7 people) are required to cooperate. [0005] 2. Bo...

AI Technical Summary

Problems solved by technology

[0004] 1. There are many plug-in valves, the operation is cumbersome and requires a lot of staff (generally 6-7 people) to cooperate

[0005] 2. Both the hopper and the chute are open, and there are many docking points and many dead ends, which will easily cause the accumulation of residual concrete, which is troublesome to clean. If the cleaning is not complete, the residual concrete in this part will solidify and make the equipment difficult to use or unusable

[0006] 3. Concrete is conveyed without pressure and flows down by its own weight. The arrangement of the chute requires a certain angle

The concrete remaining in the replaced pump pipe needs to be cleaned and cleaned in time, which requires a lot of work and labor intensity, and takes a long time

[0008] 5. The pumping concrete is interrupted for a long time, and the slump loss of the concrete stranded in the pump pipe is easy to cause pipe blockage, and the newly poured concrete and the previously poured concrete are likely to form cold joints that affect the pouring quality; frequent replacement of the pumping interface, overflowing Cleaning of concrete and residual concrete in pipes, causing waste and contamination on site
