Abstract
The present invention relates to transmission line tower foundation field, it is the telescopic base structure of a kind of mountain area small load providing in mountain area transport and deficiency present on economy for existing transmission line tower foundation.Bottom base expanding and base expanding including the sleeve shaft being embedded in below ground with sleeve shaft integral structure, bottom base expanding and base expanding is located at the lower end of sleeve shaft, base expanding and base expanding overall frontal plane of projection in bottom is circular configuration, the upper end diameter of bottom base expanding and base expanding is less than lower end diameter, is provided with the hole slot of power supply line bar insertion in sleeve shaft.The design of the oblique anchor pole of the present invention can improve pole-foundation stability against overturning, foundation bottom is designed as upper end diameter and is less than lower end diameter, make basis not only can improve pole-foundation stability against overturning, and breakout capacity can be effectively improved, make this basis be suitable for the telescopic base structure of mountain area small load.
Description
Technical field
The invention belongs to transmission line tower foundation field, a kind of specifically telescopic base structure of mountain area small load.
Background technology
Development line corridor condition with China's economic society and power grid construction becomes increasingly complex, and needs base area in mountain area
The conditions such as shape geology natural environment, using new clinoform pole and tower foundation engineering scheme, select to appear using height in good time
Basis.The foundation main of 10kV overhead transmission line cement pole to comprise direct burial basis, chassis+chuck basic, telescopic basis and
Footing foundation.But for the 10kV circuit cement pole of mountain area, the especially larger corner cement pole of root bending moment, in order to ensure
The stablizing and need certain stable side slope protection domain of basis, conventional footing foundation is not suitable for greatly due to excavation face very much
Mountain area, chassis+chuck basis is big due to volume, and heavy is not easy to transport, the basic and telescopic basis of direct burial in mountain area
Need to improve foundation bearing capacity by buried thus uneconomical.Therefore design a kind of mountain area " upper anchor draws-lower base expanding and base expanding " telescopic
Basis is necessary.
Content of the invention
The purpose of the present invention is in mountain area transport and deficiency present on economy for existing transmission line tower foundation
The telescopic base structure of a kind of mountain area small load providing.
To achieve these goals, the technical solution used in the present invention is：
The telescopic base structure of mountain area small load, ties including the sleeve shaft being embedded in below ground with sleeve shaft integral type
The bottom base expanding and base expanding of structure, bottom base expanding and base expanding is located at the lower end of sleeve shaft, and base expanding and base expanding overall frontal plane of projection in bottom is circular configuration, bottom
The upper end diameter of base expanding and base expanding is less than lower end diameter, is provided with the hole slot of power supply line bar insertion in sleeve shaft.
Multiple oblique anchor poles are distributed with shaft periphery circular array, the angle between oblique anchor pole and shaft is 30-60 degree
Between any value.
Be provided with bar construction in sleeve shaft, this bar construction includes sleeve cage bar and sleeve stirrup, sleeve stirrup with
Sleeve cage bar is welded.
Described oblique anchor pole is upper and lower double-layer structure.
Described bottom base expanding and base expanding is in truncated cone-shaped structure.
Beneficial effects of the present invention：The design of the oblique anchor pole of the present invention can improve pole-foundation stability against overturning, by basis
Bottom design is less than lower end diameter for upper end diameter, makes basis not only can improve pole-foundation stability against overturning, and can have
Effect improves breakout capacity, makes this basis be suitable for the telescopic base structure of mountain area small load.

Double-layer structure up and down.Every layer at least three, the angle between oblique anchor pole and shaft is any value between 30-60 degree, tiltedly
Anchor pole one end is connected with shaft, and the other end extends in ground, is fixed by setscrew.It is provided with reinforcing bar knot in sleeve shaft
Structure, this bar construction includes sleeve cage bar 5 and sleeve stirrup 6, and sleeve stirrup is welded with sleeve cage bar.Described bottom base expanding and base expanding is in
Truncated cone-shaped structure.The inclination angle of the diameter on the height of bottom base expanding and base expanding and chassis and base expanding and base expanding determines according to soil condition.
Ultimate principle, principal character and the advantages of the present invention of the present invention have been shown and described above.The technology of the industry
, it should be appreciated that the present invention is not restricted to the described embodiments, the simply explanation described in above-described embodiment and description is originally for personnel
The principle of invention, without departing from the spirit and scope of the present invention, the simple change of those ordinary skill in the art
It is all within protection scope of the present invention with replacing.
