Description

Technical Field

[0001] The utility model relates to the technical field of slope anchor construction, in particular to a reusable anchor hole positioning bracket. Background Art

[0002] During the construction of large slope anchors, the anchor is one of the important support structures. Usually, a drilling device is first used to perform drilling operations, and then the anchor is inserted into the drilled hole for installation. Subsequently, grouting construction needs to be carried out to make the slurry wrap the anchor. However, due to gravity, the anchor often naturally sags after being inserted into the drilled hole. This natural sag causes the lower end of the anchor to lean against the lower part of the hole wall of the drilled hole, resulting in the following problems: During the grouting process, since the anchor leans against the hole wall, the slurry cannot evenly fill the gaps around the anchor, forming a discontinuous or uneven protective layer. The function of the protective layer is to prevent the direct contact between the anchor and the external environment, thereby preventing corrosion. Due to the incomplete or too thin protective layer, the anchor is more vulnerable to the erosion of air and moisture and undergoes corrosion. Corrosion will weaken the mechanical strength of the anchor and reduce its support effect. Thereby reducing the service life of the project. The early failure of the anchor will cause the project to require frequent maintenance or even reconstruction, increasing the construction and maintenance costs. Summary of the Invention

[0003] In order to solve the above problems, the purpose of the utility model is to provide a reusable anchor hole positioning bracket, which has the following advantages: accurate positioning, which can ensure that the anchor is centered in the drilled hole, avoiding natural sag, so as to ensure that the slurry can evenly wrap the anchor; and it is reusable. After the bracket completes the positioning and support tasks, it can be conveniently disassembled and recycled, reducing the construction cost; at the same time, it has strong adaptability, can adapt to anchors of different diameters and lengths, and can be adjusted to adapt to slopes of different angles, meeting the requirements of various complex construction environments.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions: A reusable anchor hole positioning bracket, comprising:

[0005] A bracket main body, the top of the bracket main body is used for placing the anchor;

One end of the fixed base is connected to the bottom of the bracket main body, and an angle adjustment device is provided at the connection. The angle adjustment device can adjust the relative angle between the fixed base and the bracket main body, suitable for slopes with different inclination angles.

[0008] The support main body provides a strong support structure to ensure that it will not deform or be damaged during the construction process; the anchor rod limit seat is used to fix the position of the anchor rod, which can be adjusted according to the diameter of the anchor rod, increasing the versatility of the positioning frame, ensuring that the anchor rod remains centered in the drill hole, preventing natural sagging, and improving the grouting quality; the fixed base is used to stabilize the fixed position of the positioning frame on the ground, providing stability to ensure that the positioning support will not move or tilt during the construction process, providing additional stability to adapt to uneven ground, and the fixed base can adapt to different terrains to ensure that the positioning frame can also work stably on uneven ground; the angle adjustment device is used to adjust the inclination angle between the positioning frame and the slope, adapting to various angles, capable of adapting to slope construction with different inclination angles, with high stability, and the angle adjustment device can fix the angle of the positioning frame to prevent sliding or tilting during the construction process. During construction, the anchor rod, the fixed base, and the support main body form a triangle with high stability; and it can be folded and stored after construction. When storing, the fixed base is separated from the slope and lifted, and folded towards the support main body.

The two connecting pieces are sleeved on the top of the support main body and can move on the top of the support main body according to the diameter of the anchor rod. The limiting pieces are arranged on the connecting pieces to limit the anchor rod in the left-right direction.

[0014] If the diameter of the anchor rod is large, the two limiting pieces are separated from each other through the connecting piece, and the space between the two limiting pieces is used to place the anchor rod; if the diameter of the anchor rod is small, the two limiting pieces approach each other through the connecting piece, and the space between the two limiting pieces is used to place the anchor rod; therefore, it can be adjusted according to the diameter of the anchor rod, so that the anchor rod is in the centered position and ensures that the position of the anchor rod remains unchanged during the construction process.
