[0047] In other embodiments, both ends of the screw shaft 4 are provided with universal joints 10, and the outer side of the universal joint 10 is provided with a rubber protective sleeve 11 to prevent slurry erosion.

When grouting, a grille with a particle size of 6 mm is used, and when spraying, a grille with a particle size of 12 mm is used.

[0053] Before the materials in the tank truck enter the slurry tank, they are filtered through a grid to remove large particles of impurities to prevent blockage during the grouting process and ensure smooth grouting.

The device is equipped with a safety warning function to improve the safety of construction personnel's operation, and the oil injection lubrication component is used to achieve the lubrication effect of the motor and transmission parts, thereby extending the service life of the whole machine.

[0060] During the specific construction:

[0061] The main grouting pipe is connected to the grouting pipe of the liquid distribution trolley at the pump head. The liquid distribution trolley is connected to the two grouting pipes A and B through branch pipelines. When grouting the anchor, you only need to set the maximum pressure of the pump head and the maximum pressure value at the A and B grouting pipes. The pump head pressure must be equal to or greater than the pressure at AB. If the setting is wrong, the system will alarm. Press the reset button to reset it. During normal pouring, when hole A is full, the slurry will be injected into hole B with an accelerated flow rate and increased pressure. If hole B is also filled, the pressure gradually increases. When the set maximum pressure value is reached, the pressure holding mode is entered. The pressure holding time is also set in advance in the PLC control cabinet. After the pressure holding time is over, the electric valve automatically closes (suitable for automatic grouting of sealing holes) and the main pump automatically stops.

[0062] When grouting anti-floating anchor rods, this working condition does not require a liquid separation trolley assembly. It is only necessary to connect a main pipe that is one size larger than the AB hole grouting pipe from the pump head, and connect the end of the main pipe to a branching device. The outlets of the branching device are connected to the AB grouting pipes respectively. The AB grouting pipes are respectively equipped with manual ball valves. Before grouting construction, the maximum pressure needs to be input into the PLC system (there are flow meters and pressure sensors at the pump head). The AB pipes are grouted at the same time. When the A hole is full (the workers manually determine the grouting effect on site to determine whether the grouting is qualified or not), the slurry will be grouted to the B hole with an increased flow rate and pressure. As long as it does not exceed the set pressure, the grouting pressure will be increased. When the grouting of hole B is completed, close the valve of pipe B, insert it into the next anchor hole, open the valve for grouting, and repeat this cycle. As long as one of the valves is closed, the system will automatically adjust the grouting pressure by adjusting the speed of the main pump, and operate between the maximum grouting pressure and the minimum grouting pressure. If the two valves are closed at the same time or the pipeline is blocked, the pressure will rise to the maximum grouting pressure. At this time, the system will close the main pump, and when the valve is opened, the main pump can be automatically started for normal grouting.

[0063] The anti-floating anchor grouting only has data such as grouting time, total grouting volume, and pressure of each automatic start and stop of the system. There is no single-hole grouting data. When performing sealing grouting, you only need to set the maximum grouting pressure, pressure holding time, and grouting volume data. When grouting, the maximum grouting pressure and the grouting setting are the two parameters that arrive first. However, the quality of the two holes AB grouted at the same time is determined by the maximum grouting pressure. If the grouting volume reaches the set value, the equipment automatically stops. If the grouting pressure is not reached, you need to manually press the grouting operation button to continue grouting until the maximum grouting pressure (preset) is reached and then enter the pressure holding grouting. Only then can the grouting hole be qualified. The system will automatically switch to the next set of grouting operation programs, and so on, allowing workers to easily construct and strictly control the quality of the project.

[0064] It should be noted that when performing wet spraying or double liquid grouting, only one main pump grouting pipe can be equipped with a 20% or less quick-setting agent dosage. This equipment cannot be used for 1:1 double liquid water plugging grouting. If 1:1 double liquid grouting is required, a high-power quick-setting agent pump must be equipped!

[0065] The grouting parameters of this system can be set, including constant pressure grouting, constant volume grouting, overpressure protection, pressure-maintaining grouting, and continuous grouting operations, which are highly safe to use. The grouting data can be displayed in real time through the touch screen on the intelligent electrical control cabinet, and the data can be saved and printed.

[0066] As for the device and the method of use disclosed in the embodiment, since they correspond to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0067] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
