Intelligent non-pulse grouting pump for indoor model test and using method of intelligent non-pulse grouting pump

Abstract

The embodiment of the invention provides an intelligent non-pulse grouting pump for an indoor model test and a using method of the intelligent non-pulse grouting pump. The grouting pump comprises a pump body, a piston rod, a pumping system, a slurry storage tank, a slurry conveying pipe, a slurry discharging pipe, a hydraulic system and a PLC control system. The using method comprises the steps that the PLC control system sets the grouting pressure or the grouting speed, transmits signals to the hydraulic system and adjusts and propels an oil cylinder to control the reciprocating motion of thepiston; when the piston moves upwards, a steel ball in the upper part seals a rod cavity, the size is reduced, and grouting is realized; and when the piston moves downwards, a steel ball in the lowerpart seals a rodless cavity, the size is reduced, and grouting is realized. According to the intelligent non-pulse grouting pump for the indoor model test and the using method of the intelligent non-pulse grouting pump, high-flow, high-pressure and high-precision grouting requirements can be met, quantitative control and monitoring can be effectively realized on the grouting amount and the grouting speed, and meanwhile, during the reciprocating motion, the same grouting amount is achieved at the same grouting speed, so that the guarantee is provided for achieving accurate control; and the test data are easy to collect, so that the grouting pump can be widely applied to the indoor model test.

Description

technical field [0001] The invention relates to the technical field of grouting pumps, in particular to an intelligent non-pulse grouting pump for indoor model tests and a usage method thereof. Background technique [0002] Grouting is widely used in various practical projects, especially in the process of shield tunneling, grouting behind the wall and secondary grouting are very important construction procedures. At present, tunnel construction at home and abroad is in full swing, especially the construction of shield tunnels is also increasing, and the construction environment faced by builders is becoming increasingly complex. During the grouting process, factors such as grouting pressure and grouting volume cannot be determined clearly, which have a huge impact on shield tunneling efficiency and tunneling posture, and it is urgent to conduct research and exploration through laboratory tests. [0003] Compared with the actual grouting project, the indoor grouting test ha...

At present, tunnel construction at home and abroad is in full swing, especially the construction of shield tunnels is also increasing, and the construction environment faced by builders is becoming increasingly complex. During the grouting process, factors such as grouting pressure and grouting volume are not clear, which have a huge impact on shield tunneling efficiency and tunneling posture, so it is urgent to conduct research and exploration through laboratory tests

[0003] Compared with the actual grouting project, the indoor grouting test has different requirements on the grouting pump. The indoor grouting test focuses more on the precise measurement and control of the test data; small flow and stable grouting pressure are the prerequisites for data measurement, while At present, the grouting pumps on the market generally have the problem of unstable grouting pressure and inability to accurately quantify the control, which is difficult to meet the needs of indoor model tests.
