Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a pump pipe device of a concrete pouring automobile pump and a construction method thereof. Background Art

[0002] Concrete pouring construction often uses automobile pumps, commonly known as sky pumps. During pouring, concrete is transported from the pumping device through the sky pump pipe and the hose section at the end to the construction surface to be poured. However, once the pump is turned on during the pouring process, the concrete in the hose section of the discharge port cannot and is not easy to stop at any time. Often accompanied by stopping the pumping, the hose section still has concrete flowing down naturally due to gravity, and the concrete "drips" to the working surface, polluting the working surface, which is not convenient for the arrangement of the pouring process and the cleanliness and protection of the working surface, especially when pouring high and low grade concrete in the core area of ​​the wall column and beam slab. Since the national construction specifications explicitly prohibit low-grade concrete from flowing into the high-grade area, on the contrary, high-grade concrete flowing into the low-grade area will cause mixed pouring or waste, so a concrete pouring automobile pump discharge port receiving hopper device is invented. When the pouring stops, the concrete is promptly and conveniently converted and stored in the receiving hopper to solve the problem that the end cannot be stopped at any time during pumping and the "dripping" urine cannot be exhausted. Summary of the invention

[0003] In order to overcome the defects of the prior art, a pump pipe device of a concrete pouring automobile pump and a construction method thereof are provided to solve the problem that the end of the pump pipe cannot be stopped at will and the "dripping" phenomenon cannot be completely solved during concrete pouring pumping.

[0004] In order to achieve the above object, a pump pipe device for a concrete pouring automobile pump is provided, comprising:
