Description

Technical Field:

[0001] The utility model relates to the technical field of corner towers, and specifically relates to a soil protection structure for the legs of a corner tower. Background Art:

[0002] The tower leg is an important part of the tower structure, mainly used to support and fix the tower body, and enhance the stability and load-bearing capacity of the tower.

[0003] The current problem is that since the corner tower is a tower type used to change the direction of the conductor, it is usually used at the corner of the collector line or where the river is crossed. During the construction process, it is inevitable to be built near the river or near the farmland. Due to the influence of farmland cultivation, terrain changes, and various constructions, it is often found that the tower feet of the transmission tower are buried by soil, resulting in corrosion on the surface of the bolts at the connection between the bottom of the tower leg and the tower feet and loosening of the nuts, which may cause the tower to collapse and pose a serious safety hazard to the surrounding area. Content of the Utility Model:

[0004] The purpose of the utility model is to provide a soil protection structure for the legs of a corner tower to solve the problems raised in the above background art.

[0005] The utility model is implemented by the following technical solutions:

[0006] A soil protection structure for the legs of a corner tower includes a tower foundation, tower feet, and tower leg main material angle steels; the tower feet are inserted on four studs of the tower foundation and fixedly connected through clamping nuts, the tower leg main material angle steels are fixed on the tower feet by bolts, and further includes waterproof tape, a sleeve, a first epoxy resin mortar layer, a rain cap, and a guard plate; the waterproof tape is wound on the surface of the studs, and the sleeve is sleeved outside the waterproof tape, a first epoxy resin mortar layer is poured between the waterproof tape and the sleeve, the rain cap is buckled on the outer surface of the upper end of the sleeve, the guard plate is fixed on the tower feet by bolts, the guard plate covers the bottom of the tower leg main material angle steels between the tower feet and the guard plate, and a grouting space is left between the guard plate and the tower leg main material angle steels, and a second epoxy resin mortar layer is poured in the grouting space.

[0007] Preferably, both the sleeve and the rain cap are made of PVC material, and the lower end surface of the sleeve fits with the upper surface of the tower feet.

[0008] Preferably, the structure of the guard plate is in an "M" shape, and the inner surfaces of both ends thereof fit with the two end faces of the tower leg main material angle steels, and the lower end surface fits with the upper surface of the tower feet.

[0009] Advantages of the present utility model: A firm protective layer is formed for the stud and the clamping nut through the waterproof tape and the first epoxy resin mortar layer, which can prevent the loosening and rusting of the clamping nut on the tower foot and the tower foundation. At the same time, the sleeve can effectively protect the first epoxy resin mortar layer from abrasion. The rain cap is buckled on the outer surface of the upper end of the sleeve, which can block rainwater or soil. A firm protective layer is formed through the second epoxy resin mortar layer, which can prevent the loosening and rusting of the nut at the connection between the bottom of the tower leg and the tower foot. The protection plate can effectively protect the second epoxy resin mortar layer from abrasion. Brief Description of the Drawings:

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0016] Please refer to Figures 1-4 , the present utility model provides a technical solution for the soil protection structure of the corner tower leg:

[0017] A soil protection structure for the leg of a corner tower, comprising a steel tower foundation 1, a tower foot 2 and a main angle steel 3 of the tower leg; the tower foot 2 is inserted on four studs 1.1 of the steel tower foundation 1 and fixedly connected through clamping nuts 1.2, and the main angle steel 3 of the tower leg is fixed on the tower foot 2 by bolts. It also includes a waterproof tape 4, a sleeve 5, a first epoxy resin mortar layer 6, a rain cap 7 and a guard plate 8; wherein both the sleeve 5 and the rain cap 7 are made of PVC material. The waterproof tape 4 is wound on the surface of the stud 1.1, and the sleeve 5 is sleeved outside the waterproof tape 4, and the lower end surface of the sleeve 5 is attached to the upper surface of the tower foot 2. A first epoxy resin mortar layer 6 is poured between the waterproof tape 4 and the sleeve 5. The waterproof tape 4 and the first epoxy resin mortar layer 6 form a solid protective layer for the stud 1.1 and the clamping nut 1.2, which can prevent the loosening and rusting of the clamping nut 1.2. At the same time, the sleeve 5 can effectively protect the first epoxy resin mortar layer 6 from abrasion. The rain cap 7 is buckled on the outer surface of the upper end of the sleeve 5, which can block rainwater or soil.

[0018] Since the existing main angle steel 3 of the tower leg is basically fixed on the tower foot 2 by double bolts, and the structure of the guard plate 8 is in an "M" shape, the guard plate 8 can be fixed on the tower foot 2 by being clamped between two bolts, so that the guard plate 8 covers the bottom of the main angle steel 3 of the tower leg between the tower foot 2 and the guard plate 8. At this time, the inner surfaces of both ends of the guard plate 8 are attached to the two end faces of the main angle steel 3 of the tower leg, and the lower end surface of the guard plate 8 is attached to the upper surface of the tower foot 2. A grouting space 9 is formed between the guard plate 8 and the main angle steel 3 of the tower leg. A second epoxy resin mortar layer 10 is poured in the grouting space 9 to form a solid protective layer, which can prevent the loosening and rusting of the nut. The guard plate 8 can effectively protect the second epoxy resin mortar layer 10 from abrasion.

[0019] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
