Description

Technical Field

[0001] This utility model provides a deep-hole grouting and water-blocking device for underground roadways, belonging to the field of grouting and water-blocking technology. Background Technology

[0002] In underground tunnel construction, grouting is generally used to seal water sources. Underground water-blocking grouting involves injecting specific grout under high pressure into rock fissures, voids, or tunnels, allowing it to diffuse, solidify, and harden, thereby sealing water sources and reinforcing the strata. This method is widely used in mine water hazard control, effectively cutting off dangerous water sources, reinforcing rock strata, blocking voids, improving working conditions, and reducing drainage costs. Currently, deep-hole grouting for water blocking in underground tunnels generally requires the use of appropriate grouting equipment.

[0003] Existing deep-hole grouting and water-blocking equipment for underground roadways can basically meet normal usage needs. The equipment generally includes a grouting pump, a discharge pipe connected to the pump's outlet, a spray nozzle connected to the discharge pipe's port, and a mixing tank connected to the pump's inlet. In use, by starting the grouting pump, the grout mixed in the mixing tank is sprayed through the pump and discharge pipe from the spray nozzle into the deep hole of the underground roadway to be grouted and blocked, sealing the water outlet. However, before use, it is usually necessary to manually add various grouting materials to the mixing tank in sequence, and then manually stir the various grouting materials in the mixing tank using a stirring rod. This is relatively time-consuming and labor-intensive, and the grout may not mix evenly between the upper and lower layers, thus affecting the grouting and water-blocking effect. Therefore, this utility model provides a deep-hole grouting and water-blocking device for underground roadways. Utility Model Content

[0004] The technical problem solved by this utility model is that it is necessary to manually add various grouting materials into the mixing bucket in sequence and then manually stir them, which is relatively time-consuming and labor-intensive. The grouting liquid is unevenly mixed between the upper and lower layers, which affects the grouting and water-blocking effect.

[0005] To solve the technical problem, the technical solution provided by this utility model is as follows: a deep hole grouting and water plugging device for underground roadways, including a base plate, a grouting pump on the top of the base plate, a feeding assembly connected to the inlet of the grouting pump, the feeding assembly including a mixing tank, a discharge pipe connected to the inlet of the grouting pump at the bottom of the mixing tank, a stirring part on the mixing tank, the stirring part including a motor fixedly installed at the center of the top of the mixing tank, the output end of the motor being fixedly connected to a stirring blade placed inside the mixing tank; and a plurality of batching hoppers arranged around the circumference of the motor on the top of the mixing tank.

[0006] Furthermore, the number of batching hoppers is not less than three, each batching hopper is provided with graduation lines, and each batching hopper is provided with a flow control valve at its bottom discharge port and discharge pipe.

[0007] Furthermore, a support plate is fixedly connected between the two side walls of the mixing box and the top of the bottom plate.

[0008] Furthermore, the discharge port of the grouting pump is provided with a connected slurry pipe, and the port of the slurry pipe is provided with a slurry nozzle.

[0009] Furthermore, the top of the base plate is provided with storage boxes placed on both sides of the grouting pump.

[0010] Furthermore, the bottom of the base plate is symmetrically provided with casters on both sides, and the top of the base plate is symmetrically provided with push handles.

[0011] The beneficial effects of this utility model are:

[0012] By adding several grouting materials into each batching hopper, and then adding the grouting materials from each batching hopper into the mixing tank in any order, the motor drives the stirring blades to rotate, which can mix the several grouting materials added to the mixing tank. Compared with the traditional method of manually adding grouting materials in sequence and then manually stirring, this method is more time-saving and labor-saving, and can ensure that the grouting materials are fully mixed to obtain a uniform grouting liquid, so as to avoid uneven mixing of the upper and lower layers of the grouting liquid, which would affect the grouting and water-blocking effect.

[0021] According to the appendix Figure 1 , 3 As shown in Figure 4: This utility model provides a deep-hole grouting and water-blocking device for underground roadways: it includes a base plate 1, a grouting pump 2 on the top of the base plate 1, and a feeding assembly 3 connected to the inlet of the grouting pump 2. The feeding assembly 3 includes a mixing tank 4, and a support plate 12 is fixedly connected between the two side walls of the mixing tank 4 and the top of the base plate 1 to strengthen the support of the mixing tank 4. The bottom of the mixing tank 4 is provided with a discharge pipe 8 connected to the inlet of the grouting pump 2. The mixing tank 4 is provided with a stirring part 5, which includes a motor 6 fixedly installed at the center of the top of the mixing tank 4. The output end of the motor 6 is fixedly connected to a stirring blade 7 placed inside the mixing tank 4. Several batching hoppers 9 are arranged around the circumference of the motor 6 on the top of the mixing tank 4. The number of batching hoppers 9 is not less than three. The batching hoppers 9 are provided with scale lines 10. Specifically, the grouting raw materials in each batching hopper 9 are added to the mixing tank 4. The motor 6 is started to drive the stirring blade 7 to rotate, which can stir and mix the several kinds of grouting raw materials added to the mixing tank 4.

[0022] As per the instruction manual Figure 2 , 3 As shown: The bottom discharge port of the batching hopper 9 and the discharge pipe 8 are both equipped with flow control valves 11.

The discharge port of the grouting pump 2 is equipped with a connected slurry outlet pipe 13, and the port of the slurry outlet pipe 13 is equipped with a spray nozzle 14. Specifically, the grouting pump 2 is a mature existing technology. When the grouting pump 2 is started, the flow control valve 11 on the discharge pipe 8 is opened. The grouting liquid that is mixed evenly in the mixing box 4 is transported to the slurry outlet pipe 13 through the grouting pump 2, and finally the grouting liquid is sprayed out from the spray nozzle 14.

[0023] As per the instruction manual Figure 1 As shown: The top of the base plate 1 is provided with storage boxes 15 placed on both sides of the grouting pump 2 for convenient storage of grouting materials, tools, etc.

[0024] The principle of this utility model

[0025] In use, several grouting materials are added to each batching hopper 9, and the flow control valve 11 on the bottom discharge port of each batching hopper 9 is opened. The grouting materials in each batching hopper 9 are added to the mixing tank 4 in the same order. By starting the motor 6, the stirring blade 7 is rotated, which can mix the several grouting materials added to the mixing tank 4. Compared with the traditional method of adding grouting materials in order and then manually stirring, it is more time-saving and labor-saving. It can also make the grouting materials fully mixed to obtain a uniform grouting liquid, so as to avoid uneven mixing of the upper and lower layers of the grouting liquid, which would affect the grouting and water plugging effect.

[0026] After the mixing is completed, the grouting pump 2 is started and the flow control valve 11 on the feed pipe 8 is opened. The grouting liquid that is mixed evenly in the mixing box 4 is transported to the grout outlet pipe 13 through the grouting pump 2. Finally, the grouting liquid is sprayed from the spray nozzle 14 into the deep hole of the underground roadway to be grouted and plugged, so as to achieve the effect of sealing the water outlet.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
