Concrete pouring conveyor in narrow and small roof sealing space at high altitude and construction method

Abstract

The invention discloses a concrete pouring conveyor in a narrow and small roof sealing space at a high altitude. The concrete pouring conveyor comprises a cubic tank, a funnel-shaped container and a long hollow pipe, wherein the top and one side surface of the cubic tank are open, a round opening is formed at one end of the funnel-shaped container, a square opening is formed at the other end, thesquare opening end of the funnel-shaped container is connected with the opening on the side surface of the cubic tank, the round opening end of the funnel-shaped container is connected with one end ofthe long hollow pipe, a semi-circular seam is arranged in the position close to the free end of the long hollow pipe, and a movable valve plate is inlaid in the semi-circular seam. The invention further discloses a construction method of the concrete pouring conveyor in the narrow and small roof sealing space at the high altitude. The concrete pouring conveyor in the narrow and small roof sealingspace at the high altitude and the construction method have the advantages of simple construction, easy-to-control delivery amount, high efficiency, no waste, low cost, wide applicable range and lowpotential safety hazard risk, and pouring coverage is free of blind zone.

Description

technical field [0001] The invention relates to a concrete pouring conveying technology, in particular to a concrete pouring conveying device and a construction method in a high-altitude narrow ceiling space. Background technique [0002] In the prior art, the construction methods of cast-in-place concrete in the small and high-altitude capped space mainly include: (1) using automobile pumps, ground pumps or vehicle-mounted pumps to pump concrete for pouring construction; 3) Car crane or tower crane for pouring with buckets; the above method has limitations: (1) pouring coverage cannot be achieved, and there is a large blind area; (2) manual pouring efficiency is low for erecting brackets, and quality is difficult to guarantee; (3) buckets The amount of pouring is difficult to control and the waste is serious; (4) there are many processes and the construction cost is high; (5) the risk of potential safety hazards is great. [0003] The deficiencies in the conventional high-...
