The operating method for the multi-pump linkage grouting operating system of the present embodiment includes:
Specifically:
It may be understood that, according to actual needs, single-pump single-liquid static pressure grouting can be implemented by turning on a grouting on-off valve on a branch slurry inlet pipe between the grouting pump to operate and the slurry storage tank containing slurry.
When three grouting pumps need to perform single-liquid grouting simultaneously, the slurry is fed to the second slurry storage tank 8, the second grouting on-off valve 11, the fourth grouting on-off valve 16, and the sixth grouting on-off valve 21 are turned on, and the other on-off valves are all turned off, the three grouting pumps carry out single-liquid grouting operation simultaneously.
When a double-liquid grouting operation needs to be performed, double-slurry outputted before mixing is adopted. An admixture is added to the first slurry storage tank 8, a cement slurry is added to the second slurry storage tank 7, the first grouting on-off valve 9, the fourth grouting on-off valve 16, and the sixth grouting on-off valve 21 are turned on, and the other on-off valves are turned off. The first grouting pump 1 outputs the admixture, and the second grouting pump 2 and the third grouting pump 3 output the slurries. The two types of slurries, namely the admixture and cement slurry are outputted before mixing. A proportion of the two slurries are controlled by controlling the operating frequencies of the grouting pumps.
The system of the present embodiment implements a plurality of grouting processes such as single-pipe grouting and multi-pipe grouting through coordination of different on-off valves, and has a strong applicability.
The first pump body 66 and the second pump body 67 operate, so that the slurry prepared by the first mixing plant 50 can be transferred to first slurry storage tank 7 and the slurry prepared by the second mixing plant 51 can be transferred to the second slurry storage tank 8.
When only the branch slurry inlet pipes, the main slurry inlet pipes, and the grouting pump pipelines are cleaned, the corresponding cleaning on-off valves are turned on, the other on-off valves are all turned off, so that the grouting pumps operate, and under the function of the grouting pumps, water in the water tank flows through the branch slurry inlet pipes, the main slurry inlet pipes, and the grouting pumps to clean the branch slurry inlet pipes, the main slurry inlet pipes, and the grouting pump pipelines.
For example, during cleaning of pipelines of the first branch slurry inlet pipe 5, the first main slurry inlet pipe, and the first grouting pump 1, the first cleaning on-off valve 29 is turned on, so that the first grouting pump 1 operates, to drive the water in the water tank 22 to flow through the first cleaning pipe 23, the first branch slurry inlet pipe 5, and the first grouting pump 1, thereby achieving a cleaning function.
When a grouting operation is completed, the devices are withdrawn, and the slurry storage tanks, the main slurry inlet pipes, the branch slurry inlet pipes, and the grouting pump pipelines need to be cleaned, the corresponding slurry storage tank cleaning on-off valves and the grouting on-off valves on the corresponding branch slurry inlet pipes are turned on, and the other on-off valves are turned off.
For example, when two slurry storage tanks and all of the main slurry inlet pipes and branch slurry inlet pipes need to be cleaned, the first slurry storage tank cleaning on-off valve 62 and the second slurry storage tank cleaning on-off valve 64 are turned on, the third pump body 68 is started, the grouting on-off valves on all of the branch slurry inlet pipes are turned on, and all of the other on-off valves are turned off, so that the three grouting pumps operate, and under the function of the grouting pumps, the water in the main water storage tank successively flows through the slurry storage tanks, the branch slurry inlet pipes, the main slurry inlet pipes, and the grouting pumps, thereby achieving a cleaning function.
When the mixing plants, the slurry storage tanks, the main slurry inlet pipes, and the branch slurry inlet pipes need to be cleaned, for example, during cleaning of all of the mixing plants, the slurry storage tanks, the main slurry inlet pipes, and the branch slurry inlet pipes, all of the cleaning on-off valves are turned off, the water replenishing on-off valves are turned off, the water storage tank cleaning on-off valves are turned off, and all the other on-off valves are turned on, to start the third pump body 68, the first pump body 66, and the second pump body 67, so that water in the main water storage tank 56 successively flows through the mixing plants, the slurry storage tanks, the main slurry inlet pipes, the branch slurry inlet pipes, and the grouting pumps, thereby implementing a cleaning function.
By using the system of the present embodiment, the cleaning of the pipelines and the devices can be carried out automatically without manual cleaning, thereby greatly improving the operating efficiency and reducing the labor intensity.
The above descriptions are only preferred embodiments of this application, and are not intended to limit this application. For those skilled in the art, this application may have various modifications and changes. Any modification, equivalent replacement, improvement and the like made without departing from the spirit and principle of this application shall fall within the scope of protection of this application.
