Problems solved by technology

[0007] The purpose of the present invention is to provide a large-volume concrete pouring system and method, which effectively solves the problems of segregation of concrete before entering the structural layer due to the blocking of the steel skeleton, which leads to changes in the properties of the concrete, and ensures the uniformity of the concrete mixture in the structure. quality; at the same time, it solves the potential safety hazard caused by the sputtering of stones under the pouring pressure

Abstract

The invention aims to provide a mass concrete pouring system and method. The material level of concrete is sensed through wireless material level sensors arranged at different heights in a rib distribution area. When a wireless material level sensor senses that the pouring liquid level reaches the height corresponding to the wireless material level sensor, pouring is stopped, and one detachable pipe joint is detached. When the detachable pipe joints are detached, the tail detachable pipe joint is hung through a clamping device connected with a steel cable. After the detachable pipe joints are detached, the steel cable is lifted up to drive the tail detachable pipe joint to ascend to the upper detachable pipe joint. Then the two detachable pipe joints are connected, and pouring is continued. The pouring combined pipes are distributed in all areas of the rib distribution area, and the pouring process can be independently completed according to the wireless material level sensors in the areas where the pouring combined pipes are located. When the wireless material level sensor on the surface of the rib arrangement area detects concrete, the pouring combined pipe is lifted out of the rib distribution area, and pouring is completed.

Description

technical field [0001] The invention relates to the technical field of concrete structure construction, in particular to a large-volume concrete pouring system and method. Background technique [0002] Concrete pouring construction technology will have a very important impact on the quality of concrete structures. At present, concrete (especially mass concrete) is usually poured by conveying equipment flowing out of a pipeline at a position about half a meter above the steel skeleton. [0003] Engineering practice shows that the pouring process has the following two problems: [0004] (1) After the concrete leaves the pipe outlet and before entering the structural layer, it is in the accelerated state of free fall; the concrete contacts the steel skeleton at a high speed, and the larger aggregate particles are easily screened and blocked by the steel grid. As a result, the homogeneity of concrete is destroyed, segregation and other phenomena occur, and the macroscopic mate...
