Concrete pouring system with double-layer chute and construction method thereof

Abstract

The invention provides a concrete pouring system with a double-layer chute and a construction method thereof. The concrete pouring system with the double-layer chute comprises a pouring device, a chute scaffold, a chute main body, a tumbling barrel and a movable chute frame, wherein the chute main body is a double-layer chute and comprises main chutes and branch chutes; and the horizontal projections of the upper main chute and the lower main chute are overlapped. The concrete pouring system with the double-layer chute is innovative on the principle of the traditional chute; the upper chute and branching facilities thereof are added above the traditional chute; and an automobile pump is adopted in the upper chute so as to coordinate the discharging, and thus, a double-layer three-dimensional long-distance concrete pouring construction method is formed. Due to the increase in the height of the chute, the entire system can cover the pouring area of a baseplate in a relatively large area,and realizes the rapid pouring of the baseplate. In addition, when the concrete is poured on the baseplate, the demand for roads is also greatly reduced.

Description

technical field [0001] The invention relates to a pouring system, in particular to a double-layer chute and a construction method thereof. Background technique [0002] Super high-rise buildings generally use piled raft foundations, the thickness of the tower floor is large, and the amount of concrete poured at one time is large. The conventional method is to use ground pump pouring or ordinary chute construction method for concrete pouring. If the surrounding conditions are limited and the base plate is far away from the surrounding traffic roads, the conventional chute cannot meet the pouring requirements. If the ground pump is used for pouring, the pouring speed of the ground pump is slow (25-30m 3 / hour), and it is easy to block the pipe, resulting in too long concrete pouring time, prone to cold joints, and seriously affecting the quality of concrete.

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a double-layer chute concrete pouring system and its construction method, to solve the technical problems that the base plate is far away from the road and the construction at the far end of the base plate is difficult; and solve the technical problem that the investment in scaffolding is relatively high and the cost is high. To solve the technical problems that the pouring speed of the single-layer chute is slow, the ground pump is easy to block the pipe and interrupt the construction, and the construction quality cannot be guaranteed
