[0002] Grouting reinforcement is one of the commonly used methods for geotechnical engineering projects such as subways, tunnels, slopes, shafts, culverts, dams, etc. when encountering geological fracture zones, some soft rocks, easy to fall off slabs, unstable landslides, large deformations, water outflow or water inrush dangers, pipe bursts, etc. This method is to inject grouting into the rock mass through grouting anchor cables, grouting anchor rods, etc., and utilize the bonding and coagulation mechanism of the injected slurry to achieve the purpose of reinforcing the surrounding rock and significantly improve the effects of support and water blocking.
[0003] The existing injection machinery used in geotechnical engineering grouting mostly includes drilling machines, injection pumps, transmission pipes and slurry nozzles. However, this combination requires the use of too many machines and transmission pipes to participate in the production and injection of slurry, which is costly, and the grouting process is complicated and the process is relatively complex. When the mud flows out of the tank, it is relatively viscous, resulting in a slow outflow speed, which in turn prolongs the equipment operation time. Utility Model Content

[0005] The present application provides a geotechnical engineering grouting device that adopts the following technical solution:
[0006] A geotechnical engineering grouting device comprises a material tank, a stirring assembly installed inside the material tank, and an operating table placed at the lower end of the material tank for support, the top of the material tank is provided with an opening for slurry to enter, the bottom of the material tank is a hemispherical structure with a cross-sectional size gradually decreasing downward and a mounting hole is provided at the center of the bottom, a rotating drum with both ends extending out of the material tank is rotatably installed inside the material tank along an axis, a pushing screw is installed in the rotating drum, the end of the pushing screw is connected to a first motor, a stepped groove is provided in the rotating drum that is connected to the end of the rotating drum, a plurality of material holes are provided on the rotating drum between the bottom of the stepped groove and the bottom of the material tank, a mounting plate is provided in the stepped groove, and the first motor is fixedly provided on the mounting plate.
[0007] By adopting the above technical solution, the stirring assembly located inside the material tank stirs the mud, and then the mud enters the drum through the material hole. At the same time, the pushing screw located inside the drum pushes the mud out under the action of the first motor, thereby avoiding the situation where the mud is sticky and viscous and causes a slow flow out of the material tank.
[0008] Optionally, the mounting plate is connected to a stamping mechanism that drives the mounting plate to slide, and a bracket is fixedly arranged above the material tank. The stamping mechanism includes a cylinder fixedly mounted on the bracket and a connecting block connected to the end of the telescopic rod of the cylinder, and a plurality of short rods arranged along the circumference of the mounting plate are fixedly connected between the connecting block and the mounting plate.

[0018] Optionally, a scraping assembly for scraping the inner wall of the tank is provided at the end of the paddle, including a scraping rod arranged along the axis direction of the tank and a scraping member arranged at one end of the scraping rod away from the paddle.

[0021] By adopting the above technical solution, when the scraper is scraping the inner wall of the material tank, it is possible to avoid excessive accumulation of mud at a certain position on the scraper per unit time, which would cause an increase in the load on the second motor. At the same time, this structure also facilitates the mud to fall smoothly from the scraper to the bottom of the material tank, preventing the mud from splashing around again after being scraped off the inner wall of the material tank.

[0040] Reference Figure 2 and Figure 3 A stepped groove 31 is provided along the axis of the drum 3 and connected to one end of the upper end surface of the drum 3 near the material tank 1. A mounting plate 33 matching the size of the stepped groove 31 is rotatably mounted in the stepped groove 31, and the mounting plate 33 can slide in the stepped groove 31. A first motor 34 is fixedly mounted on the mounting plate 33, and the output shaft of the first motor 34 passes through the mounting plate 33. A pushing screw 4 is connected to the other end of the mounting plate 33 to push the mud flowing into the drum 3 into the ground cracks or the shaft.
[0041] Reference Figure 2 and Figure 3 A plurality of holes 32 are provided on one end of the drum 3 near the bottom of the tank 1 for the slurry to enter the drum 3.

In order to ensure the structural stability of the equipment operation, in this embodiment, the radial area of the connecting block 52 is preferably adapted to the inner wall size of the drum 3, so as to facilitate sliding in the stepped groove 31 on the drum 3.
[0044] Reference Figure 3 and Figure 4 Furthermore, an annular elastic rubber gasket 311 is installed at the bottom of the stepped groove 31 to provide a buffer when the mounting plate 33 slides in the stepped groove 31 to avoid damage to the drum 3 due to excessive impact force.

The second motor 63 can drive the rotating drum 3 and the plurality of stirring paddles 61 sleeved on the rotating drum 3 to rotate, so as to achieve stirring of the slurry inside the material tank 1.
[0047] Reference Figure 5 Specifically, the stirring paddle 61 is provided with a plurality of blades 611 along the circumference of the drum 3, and the blades 611 are symmetrically arranged in pairs along the axis direction of the drum 3, so as to fully stir the mud. In this embodiment, the number of blades 611 on each stirring paddle 61 is 2-4.

[0053] The implementation principle of a geotechnical engineering grouting device in the embodiment of the present application is:
[0054] When the equipment is working, the stirring paddle 61 on the stirring assembly 6 inside the material tank 1 rotates with the drum 3 under the drive of the second motor 63 to achieve the stirring of the mud. At the same time, the mounting plate 33 and the driving screw 4 inside the drum 3 rotate synchronously with the first motor 34, pushing the mud that enters the drum from the material tank 1 through the material hole 32 out of the material tank 1 and into the ground cracks or wells below.
[0055] After the mud is filled, the first motor 34 is stopped, and the cylinder 51 is driven to push the screw 4 to slide in the stepped groove 31 on the drum 3, so as to press the mud in the ground cracks or the tunnels to harden and reinforce them. During the operation of the equipment, the lower end of the abutment sleeve 9 is always in abutment with the ground so that the device can run smoothly and avoid splashing of mud during the punching process and vibration of the device.
