Abstract
The utility model relates to an inclined column iron tower foundation, which comprises a concrete foundation, wherein an anchoring part is obliquely arranged on the concrete foundation, and the tilt angle of the anchoring part and the tilt degree of an iron tower leg are consistent; and a force-dividing disc is arranged on the anchoring part below foundation soil, is vertical to the anchoring part, and is parallel with the concrete foundation. In construction, the inclined column iron tower foundation is put into a dug ground pit firstly, the foundation oil is backfilled to a certain height, the force-diving disc is sleeved on the anchoring part and is fixed, and then the foundation oil is backfilled, accordingly, the self weight of a tower body is transferred onto the anchoring part, and then is transferred to the force-dividing disc through the anchoring part, and thus the force-dividing disc is combined with the foundation soil to weaken most part of force of the tower body, and the small remaining part of the force is transferred onto the foundation. Accordingly, the force transferred to the anchoring part from the self weight of the tower body is firstly transferred to the force-dividing disc, and the force-dividing disc is organically combined with the foundation soil to greatly weaken the force transferred downwards to the tower body by utilizing the characteristics of the foundation oil. Accordingly, the force transferred onto the concrete foundation is very small, and the stability against overturning of the inclined column iron tower foundation is greatly improved.
Description
Technical field
The utility model belongs to electric power column foot plinth, relates in particular to a kind of basis of batter post formula electric power tower.
Background technology
Iron tower foundation is the common infrastructure in electric power transmission & distribution field, adopts the straight column type iron tower foundation of shallow embedding mostly.Because the negative profile of iron tower is up-narrow and down-wide positive ladder type mostly, the column foot of iron tower generally is to be fixed on the basic column with lateral attitude.The body of the tower deadweight is delivered on the joint face of column foot and column along column foot.The body of the tower shoe that inclines easily.For keeping stability of tower crane body, generally all pass through to increase the column cross section or strengthen ground raising security system, but adopt the ground of heavy in section column or large tracts of land hard intensity all can cause construction cost to improve.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency a kind of batter post formula iron tower foundation is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of batter post formula iron tower foundation comprises concrete foundation, and tilting in concrete foundation is provided with anchoring piece, and the angle of inclination of anchoring piece is consistent with the gradient of iron tower column foot, and the anchoring piece below foundation soil is to be provided with force disk.
Above-mentioned batter post formula iron tower foundation, said force disk is vertical with anchoring piece.
Above-mentioned batter post formula iron tower foundation, said force disk is parallel with concrete foundation.
Adopt technique scheme, the utility model has following advantage: the utility model can be put into the melt pit that digs with tilting column foot plinth earlier when construction; The backfill foundation soil is to certain height, is enclosed within force disk on the anchoring piece again and fixes, again the backfill foundation soil; The body of the tower deadweight is delivered on the anchoring piece like this; Be delivered on the force disk by anchoring piece earlier, force disk combines foundation soil to weaken the strength of most of body of the tower, and remaining few part power is delivered on the basis.The body of the tower deadweight power that passes to anchoring piece at first is delivered to force disk like this, and force disk organically combines with foundation soil, utilizes the ground soil characteristics, significantly cuts down the power of the body of the tower of biography down.The power that passes to like this on the concrete foundation is just very little; Not only improve the stability against overturning of batter post formula iron tower foundation greatly; And because the moment of flexure that acts on the anchoring piece is very little, anchoring piece can be pacified the structure electric small-size and confirmed, because the reducing of the clean reagency of ground; Make the moment of flexure act on the basis reduce, thereby base concrete and quantity of reinforcement have also reduced many accordingly.The all reasonable stress of the utility model, good stability has deviation resistance preferably.The utility model can be saved concrete and amount of reinforcement about 40%-50% by general batter post formula iron tower foundation, greatly reduces construction cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
A kind of batter post formula iron tower foundation as shown in Figure 1 comprises concrete foundation 3, and tilting in concrete foundation is provided with anchoring piece 1, and the angle of inclination of anchoring piece 1 is consistent with the gradient of iron tower column foot, and the anchoring piece below foundation soil is to be provided with force disk 2.The body of the tower deadweight power that passes to anchoring piece at first is delivered to force disk like this, and force disk organically combines with foundation soil, utilizes the ground soil characteristics, significantly cuts down the power of the body of the tower of biography down.The power that passes to like this on the concrete foundation is just very little; Not only improve the stability against overturning of batter post formula iron tower foundation greatly; And because the moment of flexure that acts on the anchoring piece is very little, anchoring piece can be pacified the structure electric small-size and confirmed, because the reducing of the clean reagency of ground; Make the moment of flexure act on the basis reduce, thereby base concrete and quantity of reinforcement have also reduced many accordingly.
The preferred structure of the utility model is as shown in Figure 1; Force disk 2 is vertical with anchoring piece 1, and it is vertical with force disk that body of the tower deadweight passes to the direction of power of anchoring piece like this, through vertically acting on the force disk; Force disk organically combines with foundation soil, weakens downwards most of and power.
The utility model can also be another kind of structure; Force disk 2 is parallel with concrete foundation 3; The body of the tower deadweight direction and the force disk that pass to the power of anchoring piece has an angle like this, and this power can be divided into a vertical force and a horizontal force, and vertical force and horizontal force all can be able to reduction on force disk.
The utility model is put into the melt pit that digs with tilting column foot plinth earlier when construction, the backfill foundation soil is to certain height; Be enclosed within force disk on the anchoring piece again and fix, backfill foundation soil again, force disk organically combines with foundation soil like this; The body of the tower deadweight is delivered on the anchoring piece like this; Be delivered on the force disk by anchoring piece earlier, force disk combines foundation soil to weaken the strength that passes under most of body of the tower, and remaining few part power is delivered on the basis.
