Abstract

The invention provides a multi-column construction method for jacking and reflowing pump concrete, which is applied to a construction site with two steel pipe columns. The method comprises the following steps: 1, arranging a construction system for jacking and reflowing pump concrete on the construction site; 2, synchronously injecting concrete to the two steel pipe columns with concrete pumps; 3, blowing a sponge ball from a branch pipe shunt on one of conveying pipe branch pipes to the conveying pipe branch pipe with an air pump and a rubber tube, so as to push out the concrete in the conveying pipe branch pipe and send the concrete to a concrete reclaiming device after the concrete passes through a conveying pipe main pipe and a conveying pipe stand pipe; and 4, blowing another sponge ball from the branch pipe shunt on another conveying pipe branch pipe to the latter conveying pipe branch pipe with the air pump and the rubber tube, so as to push out concrete in the latter conveying pipe branch pipe and send the concrete to the concrete reclaiming device after the concrete passes through the conveying pipe main pipe and the conveying pipe stand pipe. Through the adoption of the construction method, the use efficiency of the concrete conveying pumps is greatly improved; and the construction period is shortened remarkably.

Description

technical field [0001] The invention relates to a pumping concrete jacking construction technology. Background technique [0002] The traditional pumping concrete jacking construction technology is used in engineering construction. This technology is to open a hole in the lower wall of the steel pipe column with a size similar to that of the delivery pipe, and connect the concrete delivery pump to the hole with a pump tube. Under the action of pump pressure, it is continuously injected into the steel pipe column through the pump pipe until the pipe is filled with concrete. [0003] The deficiencies in the traditional pumping concrete jacking construction are as follows: 1. The concrete in the branch pipes and some main pipes cannot be reused due to dismantling and cleaning, resulting in waste; Long dismantling time leads to blockage of pump pipes, resulting in huge losses; 3. Concrete abandoned on the working surface will cause problems such as garbage removal difficulties ...
