Abstract
The utility model discloses a novel foundation structure of an electric transmission line tower. The novel foundation structure of the electric transmission line tower is characterized in that a concrete bearing platform is included, a convex platform used for fixing the electric transmission line tower is fixedly arranged in the center of the upper surface of the concrete bearing platform, a plurality of cylindrical branch pile bodies integrally distributed in a tree branch shape are fixedly arranged on the lower surface of the concrete bearing platform, the diameter of the branch pile bodies is 0.25-0.35m, the length of the branch pile bodies is 7-16m, the intersection angle value between the branch pile bodies and the concrete bearing platform is equal to that between the inclined edge of the electric transmission line tower and the concrete bearing platform, and 7-16 branch pile bodies are evenly distributed on the lower surface of each concrete bearing platform. The novel foundation structure of the electric transmission line tower has the advantages that the foundation of the tower is effectively prevented from sliding and differential settlement, the field entering requirements of construction machines can be met, and the requirements of tower loading can be met.
Description
Technical field
The utility model relates to high-tension transmission line engineering field, especially relates to a kind of foundation structure of Novel power transmission overhead line structures.
Background technology
Extensively the distributing soft foundation of marine facies, lacustrine facies and river facies deposition of China's southeastern coast and inland, be characterized in that water content is large, compressibilty is high, intensity is low, bad hydraulic permeability and many situations bury deeply, bearing capacity of foundation soil and stability often can not engineering demands.Under Soft Soil, general common slab foundation and the bored pile foundation of adopting of the foundation structure of overhead power transmission line pole tower, under Soft Soil, mainly there is following problem in pole and tower foundation at present:
1. under Soft Soil, slab foundation is under tower load condition, and stability is not fine, may produce basic slippage, differential settlement, to Lifting Method in Pole Tower Integral Hoisting is stable, impacts.
2. in overhead transmission line Practical Project, topography and geomorphology relative complex, generally be difficult to meet the turnover field requirement of large-scale apparatus, need to spend a large amount of expenses on a turnover passage, now, if pole and tower foundation adopts bored pile foundation generally can produce a large amount of surcharges, greatly increase the overall investment of engineering.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of pole and tower foundation slippage and differential settlement of effectively preventing, can meet the requirement of marching into the arena of construction apparatus, and can meet the foundation structure of the Novel power transmission overhead line structures of tower load requirement.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of foundation structure of Novel power transmission overhead line structures, comprise concrete bearing platform, the upper face center of described concrete bearing platform is fixedly installed and is useful on the fixedly boss of electric power line pole tower, and the soffit of described concrete bearing platform is fixedly installed integral body and is several columniform branch pile bodies that dendroid distributes.
The diameter of described branch's pile body is 0.25-0.35m, and length is 7-16m.
Angle value between the hypotenuse of the electric power line pole tower described in the angle value between described branch's pile body and described concrete bearing platform equals and described concrete bearing platform.Make pole and tower foundation structural stability better.
In described branch's pile body, be provided with spiral stirrup and several stressed vertical muscle, described spiral stirrup at described branch's pile body inwall along the long Spiral distribution of stake, described stressed vertical muscle distributes along described spiral stirrup inner surface even circumferential, and the upper end of described stressed vertical muscle is inserted described concrete bearing platform and is closely fixed in described concrete bearing platform.
The lower end of described electric power line pole tower is provided with column foot plate, and described column foot plate is fixed in described boss by stone bolt.
Concrete bearing platform soffit described in each is evenly distributed with the branch's pile body described in 7-16 root.
Described branch's pile body adopts concrete for making to form.
Compared with prior art, the utility model has the advantage of: the foundation structure of a kind of Novel power transmission overhead line structures of the utility model, comprise concrete bearing platform, the upper face center of concrete bearing platform is fixedly installed and is useful on the fixedly boss of electric power line pole tower, the soffit of concrete bearing platform is fixedly installed integral body and is several columniform branch pile bodies that dendroid distributes, owing to adopting dendriform pile body, thereby increased substantially bearing capacity of pile foundation; Meanwhile, pile body branch has reinforced periphery weak soil, has increased the strength and stiffness of weak soil, has improved the stability of ground, and advantage is as follows:
1,, under Soft Soil, adopt root pile basis can effectively prevent pole and tower foundation slippage and differential settlement;
2. inconvenient due to tower position turnover, Large Construction apparatus cannot be marched into the arena, and adopts root pile can meet the requirement of marching into the arena of construction apparatus, and can meet the requirement of tower load, can greatly save a construction apparatus turnover expense.
