Abstract
The invention relates to an inclined post pile foundation for an overhead transmission line. The inclined post pile foundation comprises inserted angle steel, anchoring angle steel, a concrete pile and a foundation step pile, wherein the inserted angle steel and the anchoring angle steel are fixedly arranged on the upper part and the lower part of the concrete pile respectively; an included angle of 10-20 degree is formed between the concrete pile and a vertical direction; and the foundation step pile is arranged at the bottom of the concrete pile, and is connected with the concrete pile by pouring. Compared with the prior art, the obliqueness is consistent with the gradient of an overhead transmission line bracket, so that the stress states of a foundation upright post and a bottom plate are improved greatly, the influence of foundation horizontal force on a foundation bottom plate is reduced to the maximum extent, and the stability of the foundation is enhanced remarkably; and meanwhile, the eccentric bending moment is reduced, so that the size of the controlled foundation bottom plate can be reduced correspondingly, the concrete amount and reinforcement amount of the foundation are reduced, the foundation is stressed reasonably, the anti-dumping stability is enhanced greatly, and the using amount of a foundation material can be saved by about 20 percent.
Description
Technical field
The present invention relates to a kind of pile foundation, especially relate to a kind of batter post formula pile foundation that is used for overhead transmission line.
Background technology
Conventional overhead transmission line outlet structure often adopts flush type foot joint form; Promptly stay and establish a rim of a cup at basic top; The herringbone steel pipe column is inserted in the rim of a cup; Adopt the concrete of high one-level label to fill rim of a cup again, fill and carry out at twice, treating that concreting for the second time forms just can carry out follow-up lead after the intensity and hang up work.Say from the construction angle, this method easy construction, the foundation construction required precision is not high, but long in time limit, for reconstruction and extension project, can cause twice power failure process successively.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence the batter post formula pile foundation that is used for overhead transmission line that a kind of basic principal post gradient is consistent with the transmission line of electricity support gradient, basic stress reasonable, stability against overturning improves greatly to be provided.
The object of the invention can be realized through following technical scheme:
A kind of batter post formula pile foundation that is used for overhead transmission line; This pile foundation comprises inserts angle steel, anchoring angle steel, concrete pile, footing step stake; Described insertion angle steel and anchoring angle steel are fixedly mounted on the top and the bottom of concrete pile respectively; Described concrete pile and vertical direction are 10 °～20 ° angle, and described footing step stake is located at the bottom of concrete pile, are connected with the concrete pile cast.
The top of described concrete pile is connected with the footing of transmission line of electricity support.
Be provided with main muscle in the described concrete pile, hoop is provided with stirrup around the main muscle.
Described footing step stake is a double-layer structure, is provided with step master muscle in the step of upper strata, is provided with on the base plate muscle under the muscle and base plate in lower floor's step.
Be provided with handling reinforcement between the muscle under muscle and the base plate on the described base plate.
The junction of described anchoring angle steel and concrete pile is provided with location-plate.
Compared with prior art, gradient of the present invention is consistent with the transmission line of electricity support gradient, has improved the force-bearing situation of basic column, base plate greatly; Make foundation level power drop to minimum level to the influence of sole plate, the stability on basis is significantly improved, simultaneously; Because eccentric bending moment reduces, in check sole plate size can obtain corresponding reducing, thereby reduces the amount of concrete and the quantity of reinforcement on basis; And basic stress is reasonable, and stability against overturning improves greatly, and the basic material consumption can be practiced thrift about 20%; Simultaneously can reduce land area, have good and economic and reasonability, in addition; Batter post formula pile foundation can reduce base concrete and rolled steel dosage; Accelerating construction progress reduces construction investment, is applicable to the iron tower of power transmission line of place, tower position for normal geological conditions (except the unfavorable geological conditionss such as the pool, dark creek, river course, irrigation canals and ditches).

Among the figure, 1 is that insertion angle steel, 2 is that anchoring angle steel, 3 is that concrete pile, 4 is that location-plate, 5 is that main muscle, 6 is that stirrup, 7 is that footing step stake, 8 is that step master muscle, 9 is that muscle on the base plate, 10 is that muscle under the base plate, 11 is a handling reinforcement.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
A kind of batter post formula pile foundation that is used for overhead transmission line; Its structure is as shown in Figure 1; This pile foundation comprises inserts angle steel 1, anchoring angle steel 2, concrete pile 3, footing step stake 7; Insert angle steel 1 and anchoring angle steel 2 and be fixedly mounted on the top and the bottom of concrete pile 3 respectively, as shown in Figure 2, thereby make things convenient for the fixing of concrete pile 3 and with being connected of other pile foundation or power transmission tower.Concrete pile 3 is 10 °～20 ° angle with vertical direction, thereby the gradient that guarantees batter post formula pile foundation is consistent with the transmission line of electricity support gradient.Footing step stake 7 is located at the bottom of concrete pile 3, is connected with concrete pile 3 cast.
The top of concrete pile 3 is connected with the footing of transmission line of electricity support, in concrete pile 3, is provided with main muscle 5, and hoop is provided with stirrup 6 around the main muscle 5, and anchoring angle steel 2 is provided with location-plate 4 with the junction of concrete pile 3, and concrete pile 3 is played good positioning action.
Footing step stake 7 is a double-layer structure, is provided with step master muscle 8 in the step of upper strata, is provided with on the base plate muscle 10 under the muscle 9 and base plate in lower floor's step, is being provided with handling reinforcement 11 under muscle on the base plate 9 and the base plate between the muscle 10.
Adopt the batter post basis greatly to improve the force-bearing situation of basic column, base plate, make foundation level power drop to minimum level to the influence of sole plate, the stability on basis is significantly improved.Simultaneously, because eccentric bending moment reduces, in check sole plate size can obtain corresponding reducing, thereby reduces the amount of concrete and the quantity of reinforcement on basis.
