Abstract
The invention discloses a high-voltage transmission line iron tower pile foundation structure. The high-voltage transmission line iron tower pile foundation structure comprises a pile cap, a pile, anchor rods, a foundation pit and surface soil. The upper end of the pile is arranged inside the pile cap, the pile cap is arranged inside the foundation pit, and the foundation pit is formed by digging the surface soil; the cross section of the pile cap is in an N shape, the inside of the pile cap is provided with reinforcing ribs and a reinforcing steel bar bottom plate, wherein the reinforcing ribs are arranged in a ring shape, and the reinforcing steel bar bottom plate is arranged in the center of the pile cap; the portion of the upper end of the pile, which is protruded from the bottom surface of the pile cap, is radially inclined to form a certain included angle from the vertical direction and upwards provided with threads from the anchoring bottom end of the pile. The high-voltage transmission line iron tower pile foundation structure is low in construction difficulty, high in horizontal loading capacity and tensile strength and capable of effectively bearing action force born by a high-voltage transmission line iron tower.
Description
Technical field
The present invention relates to pile foundation, be specifically related to high-voltage transmission line towers piling strtucture.
Background technology
Along with the raising of transmission line of electricity voltage conveying, the requirement of power transmission line iron tower foundation to Its ultimate bearing capacity improves thereupon, simultaneously in foundation construction process, need avoid adopting the basis of opening and digging as far as possible, improves the supporting capacity of pile foundation.
Summary of the invention
For the problems referred to above, it is large that the problem to be solved in the present invention is to provide a kind of supporting capacity, and short construction period, protection of the environment is suitable for the wide iron tower of power transmission line pile foundation of soil property scope simultaneously.
For solving the problems of the technologies described above, the technical solution used in the present invention is, a kind of high-voltage transmission line towers piling strtucture, comprise pile cap, stake, anchor pole, foundation ditch, the top layer soil body, the upper end of described stake is arranged in pile cap, and pile cap is positioned at foundation ditch, and foundation ditch excavates to form in the soil body of top layer; The cross section of described pile cap is п type, pile cap inside is provided with reinforcing rib, reinforcing bar base plate and anchor pole, and described reinforcing rib is that annular is arranged, and described anchor pole and reinforcing bar base plate are positioned at the center of pile cap, anchor pole is that annular is arranged, and reinforcing bar base plate is arranged in the inner space that anchor pole surrounds; The upper end of described stake is arranged in the part protruded pile cap bottom surface, and radial skew is arranged, and in vertical direction with certain angle, the bottom along stake is upwards provided with spiral.
As preferably, described reinforcing rib spud pile, in pile cap, prevents the rotation of stake, improves the tension pull out force ability of stake simultaneously; Reinforcing rib can effectively by stress transfer that stake is subject to on anchor pole, increase effectively the effect of the anchorage of pile foundation, reduce horizontal applied force and pulling capacity that pile is subject to simultaneously.
As preferably, described pile cap is connected with high-voltage transmission line towers.
As preferably, the height that described stake is arranged in pile cap is 30cm ~ 90cm,
As preferably, described foundation ditch excavates very shallow foundation ditch, and only on the top layer of the soil body.
Beneficial effect of the present invention, structure is simple, and difficulty of construction is little, and the horizontal loading ability of pile foundation is large, and tension pull out force ability is strong, effectively can carry the active force that high-voltage transmission line towers bears, and applicable soil property scope is wide, simultaneously to environment almost without destroying.
