Description

Technical Field

[0001] The present application relates to the technical field of grouting support, and in particular to a grouting device for a tunnel in a water-rich stratum. Background Art

[0002] In the construction of highway and railway projects, tunnel excavation is a very common construction method. During the tunnel excavation and the entire construction process, the use of advanced support operation technology is a feasible method to ensure the stability of the tunnel excavation working face and take auxiliary measures ahead of the excavation operation.

[0003] When constructing in water-rich strata, it is often necessary to first inject water glass to stop water, and then inject concrete slurry. After injecting one slurry, the machine needs to be shut down, and the equipment needs to be replaced before injecting another slurry. This is very inconvenient to operate, and manual timing is required when injecting water glass, which results in a certain error and will affect the construction to a certain extent. Utility Model Content

[0006] A grouting device for a tunnel in a water-rich stratum, comprising:

[0007] A controller, for receiving and issuing instructions;

[0008] A material storage box, wherein the interior of the material storage box is hollow and the top is open, and a partition is fixedly connected to the material storage box, and the partition divides the interior of the material storage box into a first chamber and a second chamber, the first chamber is used to hold water glass slurry, and the second chamber is used to hold double slurry;

[0031] The following is combined with Figure 1-2 This application is described in further detail.

[0032] The present application embodiment discloses a grouting device for a water-rich stratum tunnel. Figure 1 The grouting device includes a storage box 1, a grouting pump 2, a solenoid valve 3, a grouting pipeline 4, a flow meter 5, a controller 6 and a timing module 7.

[0033] Reference Figure 2 The storage box 1 is a rectangular structure, which is hollow inside and open at the top. A partition 11 is fixed inside the storage box 1. The partition 11 connects the side wall and the bottom wall of the storage box 1, and divides the inside of the storage box 1 into a first chamber 12 and a second chamber 13. The first chamber 12 is used to hold water glass slurry, and the second chamber 13 is used to hold double slurry. A top cover 14 is provided at the open end of the storage box 1, which is mainly used to prevent impurities such as leaves from floating in. The top cover 14 is provided with stirring components 8 at the positions corresponding to the first chamber 12 and the second chamber 13, respectively, which are mainly used to prevent the slurry from solidifying.

[0034] The stirring assembly 8 includes a motor 81 mounted on the top cover 14, and a spiral blade 82 fixedly connected to the output shaft of the motor 81. The spiral blade 82 extends into the first chamber 12 or the second chamber 13. When the motor 81 is started, the spiral blade 82 rotates continuously, so that the slurry is always in a flowing state for pumping.

[0035] Reference Figure 2 A vertically arranged cylinder 9 is installed on both sides of the storage box 1, and the piston rod of the cylinder 9 is set upward. A horizontal support plate 91 is fixedly connected to the piston rod of the cylinder 9, and a positioning rod 92 coaxial with the piston rod is fixedly connected to the support plate 91. Correspondingly, support plates 15 are fixedly connected to the positions corresponding to the support plates 91 on the top cover 14, and through holes are processed on the support plates 15 for the positioning rod 92 to pass through.

[0036] When opening the cover to add materials or check the slurry condition, the cylinder 9 is started, the piston rod is extended, and the top cover 14 is lifted up through the support plate 91 and the support plate 15. During this process, the positioning rod 92 limits the horizontal movement of the top cover 14.

[0037] In order to further strengthen the limiting of the top cover 14 , a latch 93 is provided on the rod body of the positioning rod 92 passing through the supporting plate 15 . When the latch 93 is in place, the surface of the latch 93 fits with the surface of the supporting plate 15 , mainly used to limit the vertical movement of the top cover 14 .

[0038] Since the top cover 14 and the stirring assembly 8 are separate from the storage box 1 and can be removed at any time, the top cover 14 can be applied to different boxes or tanks, and has high flexibility.

[0039] Reference Figure 1The grouting pump 2 is arranged outside the storage box 1, and the inlet end of the grouting pump 2 is connected to the feed pipe 21, the first conveying pipe 16 is connected between the feed pipe 21 and the first chamber 12, and the second conveying pipe 17 is connected between the feed pipe 21 and the second chamber 13; two solenoid valves 3 are provided, which are respectively installed on the first conveying pipe 16 and the second conveying pipe 17; the outlet end of the grouting pump 2 is connected to the discharge pipe 22, and the flow meter 5 is installed on the discharge pipe 22; there are multiple grouting pipes 4, all of which are connected to the discharge pipe 22.

[0040] The controller 6 can be an MCU or a PLC, which are both prior arts and will not be described in detail herein. The specific model of the controller 6 can be selected according to actual needs, and is mainly used to receive and issue instructions. The above-mentioned motor 81, cylinder 9, grouting pump 2, solenoid valve 3 and flow meter 5 are all connected to the controller 6. The timing module 7 can be a timing chip in the controller 6 or an external 555 timer, which is connected to the controller 6 and is mainly used to control the injection time of the slurry.

[0041] The implementation principle of the embodiment of the present application is as follows: during operation, the controller 6 issues a command to enable the motor 81 to drive the spiral blade 82 to continuously stir to prevent the slurry from solidifying; the solenoid valve 3 on the first conveying pipe 16 is opened, and the grouting pump 2 is started at the same time, so that the water glass slurry is extracted from the first chamber 12, and is pumped to the grouting pipe 4 along the first conveying pipe 16, the feeding pipe 21, and the discharging pipe 22 in sequence for grouting. When the water glass slurry passes through the flow meter 5, the flow meter 5 feeds back a signal to the controller 6. After receiving the signal, the controller 6 issues a command to the timing module 7 so that the timing module 7 starts timing. When the grouting time reaches a preset time, for example, ten seconds, two seconds, or more, the grouting time is equal to or less than the preset time. Ten seconds, the timing module 7 feeds back the signal to the controller 6. After receiving the signal, the controller 6 closes the solenoid valve 3 on the first conveying pipeline 16, and opens the solenoid valve 3 on the second conveying pipeline 17, so that the double slurry is pumped along the second conveying pipeline 17, the feeding pipeline 21, and the discharging pipeline 22 in turn to the grouting pipeline 4 for grouting. Similarly, when the double slurry passes through the flow meter 5, the flow meter 5 feeds back the signal to the controller 6, and the controller 6 sends an instruction to the timing module 7, so that the timing module 7 starts timing. When the grouting time reaches the preset time, the timing module 7 feeds back the signal to the controller 6, and the controller 6 closes each actuator to complete the grouting.

[0042] Compared with the technical solutions in the prior art, the grouting device in the present application is not only convenient for construction personnel to operate, but also greatly reduces the difficulty of operation, reduces errors, and improves construction efficiency.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
