Abstract

A multipoint intelligent cement paste grouting system comprises a control mechanism A, a power mechanism B, an execution mechanism C and a feedback mechanism D, and the relations between these mechanisms are as follows: the control mechanism A is connected with the power mechanism B through a control line to regulate the output power of the power mechanism B; the control mechanism A is connected with the execution mechanism C through a control line to regulate the flow in a pipeline of the execution mechanism C; the control mechanism A is connected with the feedback mechanism D through a signal line and receives a feedback signal of the feedback mechanism D; the power mechanism B is directly connected with the execution mechanism through a grouting delivery pipeline, converts mechanical energy into pressure energy and inputs the pressure energy into the execution mechanism C; the feedback mechanism D is embedded in the execution mechanism C, acquires signal parameters of all parts of the execution mechanism C in real time and feeds back the signal parameters to the control mechanism A through a signal line. The system can realize the full-automatic working process, has quick response and high accuracy for grouting pressure and flow control and can records pressure and flow data in real time.

Description

technical field [0001] The invention relates to a multi-point intelligent grouting system for cement slurry, in particular to an automatic balanced grouting system for cement slurry which has strict requirements on the reliability of the control mode when it is applied to the deviation correction grouting of subway tunnels. It belongs to the technical field of civil engineering. Background technique [0002] There are a large number of existing subway tunnels, and settlement often occurs, and reinforcement and deflection correction are required. In order not to cause the tunnel torsion during reinforcement, symmetrical grouting is required. At present, the widely used conventional method generally uses multiple grouting machines to work at the same time. During the grouting process, it takes a lot of manpower and material resources to ensure the overall grouting quality, and it is easy to cause damage to instruments or pipeline blockage due to excessive pressure. It is diffi...
