Description

Technical Field

[0001] The utility model relates to the technical field of grouting anchor rods, in particular to a slope grouting anchor rod. Background Art

[0002] Engineering slope protection includes slope protection and retaining structure protection. Common measures for slope protection include mortar or cement mortar, spraying, sprayed concrete, mortar-laid stone retaining wall, anchor spraying slope protection, anchor spraying net slope protection, etc. Such measures are mainly used to protect the excavated slope surface from weathering and peeling, fragmentation, and a small amount of falling rocks. The slope to be protected should have sufficient stability. For unstable slopes, support should be provided first and then protection should be provided. When protecting and managing the slope, grouting anchor rods should be used to inject anchoring agents such as injection resin, engineering glue, and quick-setting cement into the loose rock and soil strata of the slope.

[0003] The current anchor rods do not have a detachable blocking function. During the process of inserting the anchor rod into the required grouting area of ​​the slope, the rock and soil can easily enter the grouting groove through the grouting outlet at the insertion end of the anchor rod, causing the grouting groove to contain rock and soil, resulting in the slurry not flowing smoothly in the grouting groove, thereby affecting the slurry transportation and poor grouting effect. In addition, if the rock and soil block the grouting outlet, making it impossible for the slurry to flow into the surrounding soil, the anchor rod needs to be pulled out, cleaned, and then reinserted for grouting.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1 , Figure 2 and Figure 4 A slope grouting anchor bolt is shown, comprising:

[0028] The anchor rod body includes an outer plate 1, a grouting plug 2, a threaded rod 3, a grouting port 4 and a grouting groove 8. The grouting groove 8 is provided inside the grouting plug 2 and the threaded rod 3. The grouting plug 2 is connected to the lower end surface of the outer plate 1. The threaded rod 3 is connected to the end of the grouting plug 2 away from the outer plate 1. The grouting port 4 is connected to the upper end surface of the outer plate 1. When in use, the construction personnel insert the anchor rod into the area to be grouted, and then inject the mortar into the grouting groove 8 through the grouting port 4. The mortar flows out of the grouting port of the anchor rod through the grouting groove 8 and flows into the rock and soil, and the grouting operation can be realized;

[0029] Further, see Figure 4As shown, an outer cover 6 is provided at the lower end of the outer plate 1 and outside the threaded rod 3, and a connecting structure is provided at the connection between the outer cover 6 and the outer plate 1. The connecting structure consists of a connecting column, a connecting groove and a fastening bolt. The connecting groove is opened on the outer plate 1, and the connecting column is inserted into the inside of the connecting groove, and the lower end surface of the connecting column is connected to the outer cover 6, and the fastening bolt is threadedly connected in the bolt groove opened in the connecting column;

[0030] Specifically, the outer cover 6 can prevent the surface of the threaded rod 3 from directly contacting the mortar, so that when it is subsequently recycled, there is no need to clean the mortar on the surface of the threaded rod 3, thereby reducing the chance of wear of the threaded rod 3.

[0031] The utility model provides Figure 3 and Figure 5 A slope grouting anchor rod is shown, and a detachable plugging structure 5 is provided inside the grouting groove 8. The detachable plugging structure 5 includes a rod body 51, a plug block 52 and a top cover 53. The rod body 51 is arranged inside the grouting groove 8, and the tip of the rod body 51 passes through the outside of the grouting groove 8, the plug block 52 is connected to the upper end surface of the rod body 51, and the plug block 52 is inserted into the inside of the grouting port 4, and the top cover 53 is covered outside the grouting port 4, and the inner surface wall of the top cover 53 is connected to the plug block 52.

[0032] The detachable blocking structure 5 also includes a block groove 54 opened on the inner wall of the top cover 53, the interior of the block groove 54 is connected to an elastic block 55, the outside of the elastic block 55 and a slot 56 is opened on the outer wall of the grouting port 4, a pull rod 57 is inserted into the block groove 54, one end of the pull rod 57 is connected to the block body of the elastic block 55, and the other end of the pull rod 57 is connected to a pull block 58.

[0033] Through the above technical solution:

[0034] Before the anchor rod is inserted into the slope, the tip of the rod body 51 is first inserted into the threaded rod 3 from the grouting port 4, and the tip of the rod body 51 is just inserted into the inside of the grouting port. The plug block 52 is clamped in the grouting port 4, and the top cover 53 covers the outside of the grouting port 4. At this time, the elastic clamp block 55 is clamped into the clamping groove 56. This operation can block the grouting port, thereby preventing the rock and soil from easily entering the grouting groove 8 through the grouting port of the anchor rod during the insertion process of the anchor rod, and preventing the grouting groove 8 from containing rock and soil and causing the slurry to be injected into the grouting groove 8. The drawback of unsmooth flow in the slurry groove 8 is not affected, thereby not affecting the transportation of slurry, ensuring the grouting effect. In addition, it also prevents the rock and soil from blocking the slurry outlet and causing the slurry to be unable to flow into the surrounding soil, ensuring that the anchor rod can be grouting normally. In addition, after insertion, hold the pull block 58 and pull it, and the pull rod 57 drives the elastic card block 55 to shrink and move out of the card groove 56 into the block groove 54, and finally pull the top cover 53 outward to take out the rod body 51 without affecting the subsequent grouting operation.

[0035] The utility model provides Figure 4 and Figure 6 In the slope grouting anchor shown, a stabilizing structure 7 is provided on the outer plate 1 , and the stabilizing structure 7 is provided on the outer side of the grouting port 4 .

[0036] The stabilizing structure 7 includes a screw groove 71, a screw rod 72, an embedded pile 73 and a handle 75. The screw groove 71 is opened on the outer plate 1, the screw rod 72 is threadedly connected to the inside of the screw groove 71, the embedded pile 73 is connected to the lower end surface of the screw rod 72, and the handle 75 is connected to the upper end surface of the screw rod 72; the stabilizing structure 7 also includes a plurality of grooves 74 opened on the outer wall of the embedded pile 73.

[0037] Through the above technical solution:

[0038] After the anchor rod is inserted into the slope, the staff holds the handle 75 and turns it, and the screw rod 72 cooperates with the screw groove 71 to insert the buried pile 73 into the rock and soil. This operation can make the anchor rod have a stable supporting force, so that it strengthens the stability of the anchor rod after insertion, and avoids the situation where the anchor rod loosens and shakes during the grouting process due to poor stability, which affects the grouting effect, thereby ensuring the grouting quality. In addition, a groove 74 is opened on the buried pile 73, and the groove 74 can enhance the friction between the buried pile 73 and the rock and soil, and further enhance the firmness of the anchor rod inserted into the slope.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
