Abstract
An iron tower foundation of a power transmission line is formed by a pile body and an expanded-base end below the pile body. The pile body is formed by a slant pile body on the upper portion and a perpendicular pile body on the lower portion, and an included angle formed by the slant pile body and the perpendicular pile body is larger than 0 degree and smaller than or equal to 30 degrees. According to the technical scheme, the slant pile body can be considered to be extension of a tower leg of an iron tower, foundation acting force equivalently acts on a cross face of the slant pile body and the perpendicular pile body directly, accordingly influences of horizontal acting force in a height scope of the slant pile body can be removed, horizontal deformation of the pile body is greatly reduced, the sectional dimension of the pile body is effectively reduced, meanwhile, basically no construction difficulty is increased, and the iron tower foundation has quite considerable economic and social benefits.
Description
Technical field
The utility model relates to a kind of basis of iron tower of power transmission line.
Background technology
Existing iron tower of power transmission line basis, the vertical pore-forming pattern of the general employing in undisturbed soil basis.
As shown in Figure 1 and Figure 2, the undisturbed soil basis of in transmission line of electricity, adopting, the earth volume of excavation of foundation pit is few on the one hand, and is very little to the influence of environment, do not have the unnecessary earthwork to need to handle basically; On the other hand, can make full use of the mechanical property of undisturbed soil, both reduce concrete, can significantly reduce the basal plane excavation again, effectively reduce the Foundation Design cost.But because the influence of iron tower foundation horizontal applied force, the advantage on undisturbed soil basis can not get fully playing, and particularly basset when longer in the basis, and the influence of horizontal applied force is more serious, causes the obvious increase of base concrete amount, causes the wasting of resources.
Summary of the invention
The purpose of this utility model provides a kind ofly bassets more for a long time on the basis, can reduce the iron tower of power transmission line basis that horizontal applied force causes adverse effect.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises pile body and is positioned at the expansion bottom of pile body below, and pile body is made of the inclination pile body on top and the vertical pile body of bottom, and the angle of described inclination pile body and vertical pile body is greater than 0 ° and smaller or equal to 30 °.
The inclination pile body is identical with the tower leg master material gradient, and basic pore-forming can manually be drawn and dig, also can mechanical hole building.The end face of inclination pile body is vertical with the axis of inclination pile body.
The intersection of inclination pile body and the vertical pile body 0m～1m place that locates below ground level, the other parts of inclination pile body all are positioned at more than the ground.
Adopt the utility model of technique scheme, the inclination pile body can be considered the extension of iron tower tower leg, be equivalent to basic role power and directly act on inclination pile body and vertical pile body intersection, thereby eliminate the influence of horizontal applied force in the raked pile height degree scope, reduce the pile body horizontal distortion greatly, effectively reduce the pile body sectional dimension, simultaneously, substantially do not increase difficulty of construction, have considerable economy and society benefit.

The specific embodiment
As shown in Figure 3, Figure 4, the utility model comprises pile body and is positioned at the expansion bottom of pile body below, above-mentioned pile body is made of the inclination pile body 1 on top and the vertical pile body 2 of bottom, above-mentioned inclination pile body 1 and the angle of vertical pile body 2 can be thought the arbitrary value in 1 °, 5 °, 10 °, 20 °, 25 °, 30 ° greater than 0 ° and smaller or equal to 30 °.
Inclination pile body 1 is identical with the tower leg master material gradient, and basic pore-forming can manually be drawn and dig, also can mechanical hole building.
And the end face of inclination pile body 1 is vertical with the axis of inclination pile body 1 to be preferred forms.In addition, the intersection of inclination pile body 1 and the vertical pile body 2 0m～1m place that locates below ground level, the other parts of inclination pile body 1 all are positioned at more than the ground.
Job practices of the present utility model is: as Fig. 5, Fig. 6, shown in Figure 7, according to the tower leg master material gradient and site contour situation, choose reasonable knick point.For making things convenient for pore-forming and reinforcing cage being put into the hole smoothly, should be at first during construction according to carrying out artificial or machinery is drawn excavation construction in vertical undisturbed soil basis, according to slope requirement knick point is replenished to draw with top again and dig, after reinforcing cage is good down, draw more and dig partly and can use earthen backfill behind the formwork, also can directly use concreting.
