The ladder stands are arranged on the pole body so that a worker can climb conveniently, the pole body is of a composite structure composed of the steel pipes and the sea sand concrete layer, and the strength of the pole body is enhanced.
Description
Technical field
The utility model relates to used for transmission line concrete shaft tower, is specifically related to a kind of marine sand concrete shaft tower of convenient climbing.
Background technology
Along with the continuous high speed development of modernization power grid construction and the communication technology, shaft tower height constantly increases, and the corresponding increase of bar section diameter is thereupon stepped on bar with climbers and is only applicable to shank diameter and is less than the following electric pole of 40 mm, thereby ascend operation is brought inconvenience.Existing shaft tower is generally mixed earth shaft tower, and the mixed earth of coastal area is more rare, and cost is also higher, traditional mixed earth shaft tower, in the situation that meeting some strength, need to be strengthened concrete thickness, causes like this weight of shaft tower heavier, inconvenience is not only installed, and freight is higher.
Summary of the invention
The technical problems to be solved in the utility model is that traditional shaft tower is inconvenient to climb, and cost of production is higher, and inconvenience is installed, and freight is higher, for addressing the above problem, provides a kind of marine sand concrete shaft tower of convenient climbing.
The technical solution of the utility model realizes in the following manner:
A kind of marine sand concrete shaft tower of convenient climbing, comprise the body of rod, on the outer wall of the body of rod, be provided with one group of anchor ear, on the outer wall of anchor ear one side, be provided with cat ladder, the described body of rod comprises interior steel pipe and outer steel pipe, between interior steel pipe and outer steel pipe, be provided with marine sand concrete layer, between marine sand concrete layer and outer and inner tube, be provided with overcoat.
Above-mentioned overcoat is glass fiber reinforced composite plastic layer, and carbon fiber strengthens composite plastic layer, and boron fibre strengthens any one in composite plastic layer.
Above-mentioned anchor ear at least arranges more than two, and is two semicircle compositions, and is symmetrical, and at the outer wall of anchor ear one side, anchor ear suspension member is set.
Above-mentioned cat ladder comprises cat ladder pipe, is arranged on the pin nail on cat ladder pipe and the cat ladder suspension member on cat ladder pipe two ends is set.
Above-mentioned pin nail passes and is connected with it in the middle of cat ladder pipe.
The setting corresponding to cat ladder suspension member of above-mentioned anchor ear suspension member, at least arranges more than two and is connected by bolt.
With respect to prior art, the utility model arranges cat ladder and facilitates staff to climb on the body of rod, the body of rod is by adopting steel pipe, the composite construction of marine sand concrete layer, increase the intensity of the body of rod, when increasing the body of rod, do not need body of rod overstriking a lot, it is lower that sea sand and river sand are compared cost, more can reduce costs, higher for fear of salt content in extra large sand, corrosion steel pipe, between marine sand concrete layer and steel pipe, overcoat is set, thereby can to extra large sand, not carry out desalination just can directly use, so further reduce use cost, and can solve the problem of coastal area river sand resource exhaustion, can better utilize extra large sand.
