Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, in particular to an electric power construction ground anchor structure. Background Art

[0002] Power ground anchors are structural parts made of steel bars or steel plates with an anchoring function. They are an indispensable part of the construction of power transmission lines. Power ground anchors are mainly composed of two parts: anchor plates and anchor rods. Anchor plates are important structural components for fixing power transmission lines. They are usually made of steel bars or steel plates. Their function is to keep the power transmission lines along the line and prevent the lines from lateral deviation. Anchor rods are the parts that connect the anchor plates to the foundation. They are usually made of reinforced concrete rods or galvanized pipes.

[0003] Before installing traditional electric ground anchors, you first need to pre-drill the ground. The angle and depth of the drilling are determined according to the construction plan and the ground anchor. Secondly, the anchor rod is inserted into the hole so that its longitudinal and horizontal position and depth in the hole are correct. Finally, cement is poured into the hole and waited for solidification to complete the fixing of the ground anchor. This solution requires drilling before installing the ground anchor during the installation process, which is time-consuming, labor-intensive and inefficient.

[0004] Therefore, we propose an electric power construction ground anchor structure to solve the problem that the ground anchor needs to be installed after drilling during the installation process, which is time-consuming, labor-intensive and inefficient. Utility Model Content

[0005] The purpose of the utility model is to provide a ground anchor structure for electric power construction to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric power construction ground anchor structure, comprising an anchor rod, a cement hole is opened at the top of the anchor rod, a threaded hole is opened at the inner wall of the cement hole, an anchor plate is connected to the inner cavity of the threaded hole by a thread, a connecting block is slidably connected to the top of the anchor plate, a limiting hole is opened at the side of the anchor plate, a limiting block is slidably connected to the inner cavity of the limiting hole, a telescopic rod is fixedly connected to the side of the limiting block, a second handle is fixedly connected to the side of the telescopic rod, a spring is sleeved on the outer ring of the telescopic rod, and a spiral drill bit is welded around the anchor rod.

[0007] Preferably, a drill is provided on the top of the connection block, a first handle is fixedly connected to the side of the drill, and a fixing hole is opened on the top of the connection block.

[0008] Preferably, limit blocks, telescopic rods, second handles and springs are provided on both sides of the connection block, the size of the limit blocks is consistent with the size of the limit holes, and the limit holes are provided in two groups and are symmetrically distributed.

[0009] Preferably, a connecting column is welded to the bottom of the anchor plate, a pressing block is welded to the bottom of the connecting column, and grouting holes are opened around the anchor rod.

[0010] Preferably, the size of the lower pressing block is consistent with the size of the cement hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The ground anchor structure for power construction is to align the fixing hole in the connecting block with the anchor plate and insert it. After pulling the handles on both sides outward, move the connecting block downward to the bottom and then release the handles. The limit block is inserted into the limit hole for fixing. The drill is turned on to drive the anchor rod to rotate. The rotation of the anchor rod drives the spiral drill bit to rotate downward to drill the soil. When the drilling reaches the required depth, the initial fixation of the anchor rod can be completed. This solution solves the problem that the ground anchor needs to be installed only after drilling during the installation process, which is time-consuming, labor-intensive and inefficient.

[0013] 2. For the ground anchor structure of power construction, after the anchor rod is initially fixed, pull the handle to separate the drill and the anchor rod, rotate the anchor plate to disengage the threads around the anchor plate from the threaded hole, move upward to take out the connecting column and the pressing block, inject cement into the cement hole, align the pressing block with the cement hole after it is filled, and continue to press down until the bottom, discharge the cement through the grouting hole, and after repeated operations, screw the anchor plate in and seal it with cement to complete the grouting fixation. This grouting method can make the cement fully blend with the surrounding of the anchor rod, making the anchor rod more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Specifically, align the fixing hole 10 on the top of the connecting block 4 with the top of the anchor plate 7, and then pull the second handle 16 before inserting it. The second handle 16 drives the telescopic rod 14 to move, thereby compressing the spring 15. The telescopic rod 14 drives the limit block 13 to move, and insert it downward to the bottom and release the second handle 16. The spring 15 releases the tension and drives the limit block 13 to insert into the limit hole 17 for fixing, thereby completing the connection between the drill 5 and the anchor rod 1.

[0023] Furthermore, the drill 5 is started to insert the anchor rod 1 into the soil according to the required angle. The drill 5 drives the anchor rod 1 and the spiral drill bit 2 to rotate. The spiral drill bit 2 drills the surrounding soil to form a hole as it rotates. The initial fixation is completed after the drill reaches the required depth and the drill 5 is closed.

After repeated operations, the anchor plate 7 is screwed in, and finally the cement is sealed to the top and waited for complete solidification to complete the fixation. This solution allows the cement to fully contact the surrounding areas of the anchor rod, and after solidification, the stability of the anchor rod can be higher.
