Description

Technical field:

[0001] The utility model relates to the technical field of building engineering construction, in particular to a concrete pouring process, specifically, a movable lifting and telescopic integrated chute. Background technology:

[0002] When pouring small-structure concrete in municipal engineering and highway engineering construction, the traditional process is to use manpower to pull a small cart and a simple chute to pour concrete, which is very physically demanding and time-consuming, and cannot achieve the target construction efficiency. If the concrete is poured slowly, the initial setting of the concrete may occur, making it difficult to ensure the quality standard. Modern technology can use a sky pump or a crane for pouring. Although it promotes construction efficiency, it is not suitable for all small-structure concrete pouring due to the small volume of small-structure concrete, the high price of sky pumps and ground pumps, and the potential safety hazards caused by improper command.
