Abstract

The utility model discloses the miniature pile foundation of a kind of power transmission tower, comprise mini pile, cushion cap and sleeve, the bottom of sleeve is affixed with mini pile by the mode of concreting, the top of sleeve pass through the mode of concreting and cushion cap affixed; The utility model, by together with being cast in pile body top, cushion cap by sleeve, significantly improving the bearing capacity on pile body top, improves the shearing resistance on pile body top, bending resistance, and easy construction, quick, cost is low.

Description

The miniature pile foundation of power transmission tower
Technical field
The utility model belongs to power system Foundation Design technical field, particularly the miniature pile foundation of a kind of power transmission tower.
Background technology
At present, the basis such as main employing expanded type basis, bored concrete pile foundation, greatly slab foundation in the construction of power industry shaft tower.There is the shortcoming such as high cost, construction complexity in traditional rod tower foundation, such as: the shortcoming on large plate base formula basis is that cost is high, excavated volume large, construction is complicated; Bored concrete pile foundation cost is high, in mud soil property, difficult quality controls, and easily occurs that boring is shunk and slump; Expanded type basic engineering is simple and easy, but quantity of reinforcement and excavated volume is large, floor space is large.Therefore, traditional pole and tower foundation is not suitable for being applied to soft foundation etc. to be had in the work transmission line construction of special geologic condition.
It is the developing direction that soft foundation work transmission line is constructed that mini pile is applied in shaft tower construction.Mini pile is a kind of small-diameter cast-in-place bored pile, typically has a diameter from 0.1m to 0.5m, can arrive the larger degree of depth.In addition, mini pile aperture is little, can be applied in the construction of various soil layer.But adopt traditional mini pile, because mini pile adopts grouting concrete pile, its pile strength is low, and when being subject to horizontal force action, easily at cross section, pile body top tension side cracking, trend is destroyed, and this makes mini pile can not directly apply in pole and tower foundation.
Utility model content
The purpose of this utility model be to provide a kind of pile body top and pile crown position not easily because of by curved, cut and the miniature pile foundation of power transmission tower even destroyed that ftractures.
The technical solution realizing the utility model object is:
The miniature pile foundation of a kind of power transmission tower, comprises mini pile, cushion cap and sleeve, and the bottom of sleeve is affixed with mini pile by the mode of concreting, the top of sleeve pass through the mode of concreting and cushion cap affixed.
The utility model compared with prior art, its remarkable advantage:
The utility model, by together with being cast in pile body top, cushion cap by sleeve, significantly improving the bearing capacity on pile body top, improves the shearing resistance on pile body top, bending resistance, and easy construction, quick, cost is low.
Below in conjunction with accompanying drawing, the utility model is described in further detail.

Detailed description of the invention
Composition graphs 1 ~ Fig. 4:
The miniature pile foundation of a kind of power transmission tower of the utility model, comprises mini pile, cushion cap 1 and sleeve, and the bottom of sleeve is affixed with mini pile by the mode of concreting, the top of sleeve pass through the mode of concreting and cushion cap 1 affixed.
The lower end of sleeve is positioned at mini pile top 1/3 place.
The upper end of sleeve is positioned at lower floor's reinforcing bar 2 place of cushion cap 1.
Sleeve adopts steel matter, and lower floor's reinforcing bar 2 of upper cartridge and cushion cap 1 welds together.
Mini pile comprises miniature soldier piles 5 and miniature taper pile 4, and wherein, miniature taper pile 4 is positioned at the outside of cushion cap 1, and miniature soldier piles 5 are positioned at the inner side of cushion cap 1.
Embodiment 1:
Composition graphs 1 and Fig. 2:
The miniature pile foundation of a kind of power transmission tower, comprise miniature soldier piles 5, cushion cap 1 and miniature soldier piles sleeve 6, the bottom of miniature soldier piles sleeve 6 is affixed with mini pile by the mode of concreting, the top of miniature soldier piles sleeve 6 pass through the mode of concreting and cushion cap 1 affixed.The lower end of miniature soldier piles sleeve 6 is positioned at mini pile top 1/3 place, and upper end is positioned at lower floor's reinforcing bar 2 place of cushion cap 1; Miniature soldier piles sleeve 6 adopts steel matter, and lower floor's reinforcing bar 2 of miniature soldier piles sleeve 6 top and cushion cap 1 welds together.
Embodiment 2:
Composition graphs 3 and Fig. 4:
The miniature pile foundation of a kind of power transmission tower, comprises cushion cap 1, miniature soldier piles 5, miniature soldier piles sleeve 6, miniature taper pile 3 and miniature taper pile sleeve 4.Miniature soldier piles sleeve 6 is fixed as one to cushion cap 1, corresponding miniature soldier piles 5 respectively by concreting mode, and miniature taper pile sleeve 4 is fixed as one to cushion cap 1, corresponding miniature taper pile 3 respectively by concreting mode.Wherein, sleeve diameter is slightly larger than mini pile diameter.Sleeve upper end arrives lower floor's reinforcing bar 2 place of cushion cap 1, and sleeve lower end arrives pile body top 1/3 place.Miniature taper pile sleeve 4 upper end otch flushes with lower floor reinforcing bar.Sleeve can be glass steel material or steel material.If sleeve is steel material, then with lower floor's reinforcement welding.
The present embodiment in use, using sleeve as building mini pile template, and will not be removed, to ensure the affixed of mini pile and sleeve.Cushion cap by curved, by horizontal applied force time, this active force is passed to mini pile by sleeve.Sleeve has stronger bending resistance, shear resistance relative to concrete, so this method of attachment can promote power transmission and the stress performance of mini pile body.
