Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway subgrade technology, specifically to a slope support device for high-speed railway subgrades. Background Technology
[0002] Slope protection for high-speed railway subgrade is an important engineering measure to ensure the safe and stable operation of high-speed railways. Its purpose is to prevent the slope soil or rock from collapsing, landslides and other instability, so as to ensure the normal use of railway lines and traffic safety.
[0003] There are generally two methods of slope protection: one is to install a support device at the slope to support it, and the other is to install a traction mechanism inside the slope. The traction mechanism works with the support plate to provide safe slope protection. However, when the support plate is pulled by the traction mechanism, the slope has limited resistance to the traction mechanism, resulting in low friction. This makes the traction mechanism prone to loosening and falling off, which can lead to safety hazards after long-term use. Therefore, this utility model proposes a slope protection device for high-speed railway subgrade to solve this problem. Utility Model Content

[0008] A slope protection device for high-speed railway subgrade includes a slope body and a support plate, and further includes: a protective cylinder, wherein the slope body has an array of drilled holes, the protective cylinder is installed at the corresponding drilled holes, the protective cylinder includes a cylinder body fixedly connected to the drilled holes, and a conical plug integrally formed at one end of the cylinder body; a traction mechanism, the traction mechanism consists of a traction rod, and traction heads and positioning plates disposed at both ends of the traction rod, wherein the traction rod is disposed inside the cylinder body and the conical plug, the traction heads extend to the outside of the conical plug, the support plate has an array of clearance holes, and the positioning plates extend through the clearance holes to the outside of the support plate and abut against the outer wall of the support plate.
[0009] Furthermore, the traction rod and the traction head are fixed by welding, and the positioning plate and the traction rod are connected by threads.
[0010] Furthermore, the cylinder body is provided with an array of grooves, and each groove is equipped with a positioning rod that extends into the slope body.
[0011] Furthermore, the end of the cylinder away from the conical plug is integrally formed with a raised edge, which is adapted to a corresponding circular groove on the slope body, and the circular groove is formed on the outside of the borehole.
[0012] Furthermore, cement is poured into the drilled holes, the cylinder, and the circular groove.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a slope protection device for high-speed railway subgrade, which has the following beneficial effects:
[0015] This utility model involves drilling holes in the slope body and fixing a protective cylinder at the drilled holes. A conical plug is provided on one side of the protective cylinder. The conical plug acts as a blocking and limiting device, stopping and limiting the cement part and the traction head, preventing the traction rod and traction head from loosening and sliding. The stopping effect is good, and the position of the traction component and cement is relatively stable, thereby ensuring the pulling effect of the support plate. This effectively ensures the support safety of the support plate, the safe use of the traction mechanism, and prevents it from falling off. Consequently, the support plate does not loosen, ensuring the support effect of the support plate on the slope body and guaranteeing the stability of the high-speed railway's normal operation.

[0024] It should be noted that the slope body 1 is located around the high-speed railway subgrade. The support plate 6 is installed on the outer surface of the slope body 1 to provide safety protection for the slope body 1 and prevent landslide accidents. An array of drill holes 2 are drilled on the slope body 1. These drill holes 2 are used for the installation of the protective cylinder 4, the traction mechanism 5, and the pouring of cement, thereby achieving the tensile protection function of the support plate 6. The protective cylinder 4 consists of a cylinder body 401, a conical plug 402, etc. The cylinder body 401 is fixedly connected to the drill holes 2 of the slope body 1. The traction mechanism 5 consists of a traction rod 502, and... The system consists of a traction head 501 and a positioning plate 503 located at both ends of the traction rod 502. The traction rod 502 is located inside the cylinder 401 and the conical plug 402. The traction head 501 extends to the outside of the conical plug 402. The conical plug 402 can stop and limit the traction head 501, thereby strengthening the overall pulling effect of the traction mechanism 5 and preventing loosening caused by insufficient friction of the slope body 1. The positioning plate 503 is located on the outside of the support plate 6, thereby forming a pulling and protective effect of the support plate 6.
[0025] like Figure 3 As shown, in some embodiments, the traction rod 502 and the traction head 501 are fixed by welding, and the positioning plate 503 and the traction rod 502 are connected by threads.
[0026] It should be noted that the traction head 501 and the traction rod 502 are welded and fixed, which provides good stability. The positioning plate 503 is connected to the end of the traction rod 502 by a thread, which facilitates the safety protection of the positioning plate 503 on the outside of the support plate 6 and facilitates the assembly of the positioning plate 503. When in use, the traction rod 502 is inserted into the relief hole 7 of the support plate 6, and then the positioning plate 503 is threaded to the end of the traction rod 502.

The setting of the protruding edge 404 can increase the stress surface of the cylinder 401 and can achieve the protective function of the cylinder 401 through cement, further ensuring the positional stability of the cylinder 401.
[0031] The working principle and usage steps of this utility model are as follows: During construction, a hole 2 is first drilled in the slope body 1, and then a circular groove 3 is drilled at the end of the hole 2. Then, the traction mechanism 5 is assembled, and the traction head 501 is placed at the bottom of the hole 2. The traction rod 502 is located at the center of the hole 2.

Then, cement is poured at the hole 2, the cylinder 401 and the circular groove 3. After a certain period of time, the support plate 6 is installed. The clearance hole 7 on the support plate 6 is adapted to the traction rod 502. Then, the positioning plate 503 is threadedly connected to the end of the traction rod 502. The positioning plate 503 abuts against the outer wall of the support plate 6 to realize the pulling effect of the support plate 6.
