This geotechnical engineering slope reinforcement device fixes the geogrid module 1 on the slope through a positioning component, and inserts a sleeve 10 between the positioning sleeves 6 of adjacent positioning components, and the sleeve 10 is inserted into the cylindrical positioning piece 9 to complete the splicing of the geogrid module 1. At the same time, the laying of the concrete pouring channel composed of the sleeve 10 and the positioning component is also completed. During laying, the angle of the sleeve 10 can be controlled according to actual needs to adjust the angle of the discharge hole 8 or adjust it to the discharge hole 8. The baffle 91 is blocked, and the positioning sleeve 6 of the unassembled sleeve 10 is blocked. During pouring, concrete can be injected into one of the sleeves 10 or the positioning sleeve 6. The concrete flows out through the discharge hole 8 along the concrete pouring channel in the sleeve 10 and the positioning component to the geogrid module for pouring. During the pouring process, the angle of the discharge hole 8 can also be adjusted, and the flow rate of concrete can be controlled by controlling the area of ​​the discharge hole 8 blocked by the baffle 91, or it can be adjusted until the discharge hole 8 is completely blocked by the baffle 91, and the concrete can be distributed and adjusted.

[0023] Specifically, if there is a soil layer on the upper part of the slope that needs to be planted with vegetation, then there is no need to pour concrete here, and the discharge hole 8 there can be completely blocked by the baffle 91; for the uniformity of concrete pouring, the discharge hole 8 near the concrete injection position should be adjusted to a smaller flow rate, or during the pouring process, when the amount of concrete in this area is sufficient, the angle of the sleeve 10 can be adjusted so that the discharge hole 8 is completely blocked by the baffle 91.

[0024] In this embodiment, the clamping seat 5 is provided with a guide cylinder 11 connected with the channel 7, a movable tube 12 is movably inserted in the guide cylinder 11, a positioning sleeve 6 is provided at the outer end of the movable tube 12, a sleeve 10 is detachably inserted in the positioning sleeve 6, and a spring 13 for pushing the positioning sleeve 6 outward is provided in the guide cylinder 11. The adoption of this structure makes the positioning sleeve 6 movable, which facilitates the insertion of the sleeve 10 into the positioning sleeve 6, and after the sleeve 10 is inserted, the spring 13 can provide an elastic force to push the positioning sleeve 6 toward the sleeve 10, so that the sleeve 10 is easy to install and the positioning is reliable after installation.

[0025] In this embodiment, a slide groove 14 is provided on the side of the guide cylinder 11, and a slide rod 15 is slidably provided in the slide groove 14, and the slide rod 15 is fixedly connected to the positioning sleeve 6.

After the annular bracket 19 is clamped and positioned by the positioning seat 3 and the clamping seat 5, the end of the positioning rod 21 abuts against the positioning seat 3 or the clamping seat 5. This structure can be used to conveniently position the geogrid module 1 on the positioning assembly. Specifically, during installation, the annular bracket 19 is sleeved on the anchor rod 2, and then the connecting holes 18 provided at the corners of the geogrid module 1 are sleeved on the positioning rod 21, and the knob 4 is tightened to clamp the annular bracket 19 between the positioning seat 3 and the clamping seat 5. After clamping, the end of the positioning rod 21 abuts against the positioning seat 3 or the clamping seat 5 to prevent the corners of the geogrid module 1 from detaching from the positioning rod 21.

[0031] In this embodiment, the cylindrical positioning members 9 on the adjacent sides of the geogrid modules 1 are located on the same straight line and are staggered. This structure makes the positioning of the geogrid module 1 by the sleeve 10 more stable.

[0032] In this embodiment, the positioning sleeve 6 is detachably adapted with a blocking piece (not shown in the figure).

[0033] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
