Abstract
The utility model relates to a composite foundation pile in a power transmission line, which comprises a pile body formed by an upper excavated pile and a lower anchor pile, and is characterized in that an anchor bolt is arranged at the middle part of the upper excavated pile, main column steel bars are uniformly distributed and arranged along the circumference, foundation anchor bars which directly reach the bottom part of the lower anchor pile are further arranged, the foundation anchor bars are uniformly arranged among the main column steel bars at intervals, and stirrups are arranged inside and outside a circumference formed by the main column steel bars and the foundation anchor bars. The composite foundation pile has the advantages that the lateral bending moment generated by horizontal force and the stronger anti-pulling performance can be resisted, the structure is simple and reasonable, the engineering materials can be saved, the use is safe and reliable, the problems of great labor intensity for foundation construction, large foundation surface excavation amount, incapability of transporting excavated soil and stones away and damages to environment can be radically solved, and the respective limitations of a single excavated foundation and a single rock foundation can be further solved.
Description
Technical field
The utility model relates to a kind of power transmission sequence basis, particularly is applicable to the vast mountain area of China, hilly ground power transmission sequence composite foundation stake.
Background technology
At present, about 2/3 power transmission sequence by way of the mountain area, upper level, hills etc., its basic distinguishing feature is that the basement rock area distributions is extensive, and the different soil of cladding thickness on the basement rock.By existing design theory and design discipline, soil has different designing requirements with rock.Then waste of material is big as if designing by soil, and is also big to environment damage; If it is when then considering overburden soil on it, do not have design theory and design discipline at present, also dangerous by rock design.
At present, regional transmission line of electricity foundation pile patterns such as China northeast mainly adopt the stake of heavy excavation footing foundation, and major defect is that construction earthwork evacuation amount is big, and the steel concrete consumption is big, the foundation cost height, have greater environmental impacts.To better in vegetation, native covering layer is thicker, and rock and soil combine the area and uses the basic pattern of undisturbed soil, does not domesticly see corresponding basic pattern as yet.
In a word, though domestic power industry has been done some research work to pole and tower foundation, but all be single method for designing to single soil property, not to the method for designing of the compound soil property combination of rock (soil with), but such geological condition often appears in actual engineering, therefore demands urgently providing a kind of new foundation pile to satisfy the needs of actual engineering now.
The utility model content
The purpose of this utility model is for the geological conditions at the Tu Yan combination, and the stake of a kind of power transmission sequence composite foundation is provided,
Simple and reasonable, save the engineering material amount, safe and reliable, it is big fundamentally to solve foundation construction labour intensity, and basal plane shovel side amount is big, and the native stone under the shovel can't be transported, to the problem that environment damages, single digging foundation and single rock basis limitation have separately been solved.
The technical solution of the utility model is: comprise being drawn by top and dig stake and the pile body formed of bottom anchoring pile, it is characterized in that: top is provided with stone bolt in the middle part of drawing and digging stake, be uniformly distributed along the circumference the principal post reinforcing bar is set, and the basic dowel of anchoring pile bottom, through bottom is set, the basis dowel is disposed in an evenly spaced relation between the principal post reinforcing bar, inside and outside the circumference of principal post reinforcing bar and basic dowel formation stirrup is set.
Good effect of the present utility model is: can resist the side direction moment of flexure of horizontal force generation and stronger extraction-resistant behavior, simple and reasonable, save the engineering material amount, safe and reliable, it is big fundamentally to solve foundation construction labour intensity, and basal plane shovel side amount is big, and the native stone under the shovel can't be transported, to the problem that environment damages, single digging foundation and single rock basis limitation have separately been solved.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the principal post arrangement of reinforcement sectional drawing of Fig. 1.
The specific embodiment
See Fig. 1, concrete structure is as follows: the pile body of composite foundation stake is drawn by concrete top and is dug a 5-1 and bottom anchoring pile 5-2 forms, and top is drawn and dug a 5-1 middle part stone bolt 1 is set; Being uniformly distributed along the circumference is provided with principal post reinforcing bar 2-2, be uniformly distributed along the circumference simultaneously basic dowel 2-1 is set, and the through bottom anchoring pile 5-2 of basic dowel 2-1 bottom, basic dowel 2-1 is disposed in an evenly spaced relation between the principal post reinforcing bar 2-2; Inside and outside the circumference of principal post reinforcing bar 2-2 and basic dowel 2-1 formation, inside and outside stirrup 3-2,3-1 are set.
After the construction, top is drawn and is dug a 5-1 and be positioned at the soil body, and bottom anchoring pile 5-2 is positioned at lithosphere.By stone bolt 1 electric power tower is installed.
