Problems solved by technology

[0002] The traditional grouting machine only has the function of delivering slurry to the inner hole of the prestressed beam. Before grouting, a vacuum pump is required to vacuum the inner hole of the prestressed beam. Operation; because the vacuum pump used is another independent machine, it is necessary to connect the vacuum pump to draw a vacuum first, then remove the vacuum pump and reconnect the pipeline to operate the algae slurry. The process is complicated, and the disassembly process of the pipeline directly affects the The vacuum degree in the prestressed beam, if there is air remaining, it will cause unstable grouting quality

Abstract

An intelligent vacuum-cycle grouting machine comprises a high-speed mixing tank, a low-speed mixing tank, a grouting pump, a grouting outlet pipe and a grout returning pipe. The grout returning pipe is provided with a program-controlled three-way valve and is controlled by the program-controlled three-way valve to switch operating positions between communication with a vacuum pump and a material returning pipe. The material returning pipe is provided with a single high valve used for sealing while the vacuum pump performs vacuum operations. The grouting outlet pipe is provided with a program-controlled relief valve used for adjusting normal grouting pressure. A sensor used for detecting conveying position of grout and outputting control signals for controlling the vacuum pump to operate is arranged on a connecting pipe between the grouting outlet pipe and the grout returning pipe. The intelligent vacuum-cycle grouting machine has the advantages that the program-controlled three-way valve is used for switching between evacuating and grouting, pipeline assembly and disassembly during construction are omitted, and construction quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an intelligent vacuum circulation grouting machine. Background technique [0002] The traditional grouting machine only has the function of conveying slurry to the inner hole of the prestressed beam. Before grouting, a vacuum pump is required to vacuum the inner hole of the prestressed beam. Operation; since the vacuum pump used is another independent machine, it is necessary to connect the vacuum pump to draw a vacuum first, then remove the vacuum pump and reconnect the pipeline to operate the algae pulp. The process is complicated, and the disassembly process of the pipeline directly affects the The vacuum degree in the prestressed beam, if there is air remaining, it will cause unstable grouting quality. Contents of the invention [0003] The purpose of the present invention is to provide an intelligent vacuum cycle grouting machine with a built-in vacuum pump...
