Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete pouring, and more particularly to a movable and portable concrete auxiliary pouring device and a construction method. BACKGROUND

[0002] In domestic concrete pouring operations, ground pumps, truck pumps and spreaders are commonly used. However, in the pouring process, situations such as complex structure of upper and lower overlapping beams or cantilevered plates are often encountered. Especially when pouring the upper and lower two layers of beams or plates at the same time, due to the difficulty of the ground pump, truck pump and spreader to directly reach the discharge port of the lower structure, the construction difficulty is increased. To solve this problem, workers often use formwork, steel pipes, PVC pipes and other materials to quickly build simple chutes or string barrels, or even try to forcibly extend the discharge port into the lower structure for pouring. However, such methods not only easily lead to waste of concrete materials, but also force workers to work on high-altitude scaffolds for a long time, which poses a significant safety hazard. In addition, if the conveying distance is too long, it may also cause concrete segregation, thereby weakening the overall strength of the concrete structure.

[0003] To solve the above problems, some existing technologies improve the chute, which solves the problems of inconvenient disassembly and large space occupation of the long chute, and improves the retardation effect of coarse aggregate concrete, but cannot effectively solve the problem of pouring concrete in multiple layers of space, and the equipment is fixed and has insufficient mobility. Some existing technologies improve the height control of concrete pouring, which reduces the segregation of concrete, but still cannot solve the demand for pouring in double or multiple layers of space, and the moving range of the equipment is limited by the length of the ball screw, which increases the workload of equipment displacement when pouring in long-span structures. In addition, the auxiliary device for large-volume concrete pouring optimizes the setting of the pouring point and reduces the adverse effects on the quality of concrete, but requires a large space for use and is difficult to overcome obstacles, and faces many challenges in actual application.
