Abstract
The utility model discloses a high pile foundation structure for a transmission line tower, consisting of a plurality of high pile structure assemblies, wherein each high pile structure assembly comprises a first foundation pile, a second foundation pile, a third foundation pile used for connecting tower feet, a connecting beam, a first shear wall and a second shear wall; and two ends of the connecting beam are respectively connected with the first foundation pile and the second foundation pile, two ends of the first shear wall are respectively connected with the second foundation pile and the third foundation pile, and two ends of the second shear wall are respectively connected with the first foundation pile and the third foundation pile. The high pile foundation structure for the transmission line tower has the advantages of effectively increasing the resistance torque of the section of the foundation, improving the stress performance of the high pile foundation, greatly reducing the quantities and construction cost of the high pile foundation with greater exposure height and enhancing the durability as well as the capability of resisting accidental load of the foundation structure.
Description
Technical field
The utility model relates to a kind of basic mounting structure of iron tower of power transmission line, especially relates to high pile foundation structure.
Background technology
The height that the reinforced concrete foundation mounting structure of iron tower of power transmission line bassets is determined by topography and geomorphology.Under some special topography and geomorphologies, the height that requires basic mounting structure to basset is bigger, at this moment just probably will use high pile foundation structure, refers to that promptly the stake in the foundation structure exposes the basic mounting structure that extends certain altitude outside native face.In the prior art, high pile foundation structure adopts highrise pile cap structure as shown in fig. 1 usually.Because the iron tower of transmission line of electricity has four column foots 1 usually, each column foot 1 supports by a highrise pile cap foundation structure, wherein each cushion cap foundation structure all comprises some expose outside ground 2 and upwardly extending stakes 3, cast when certain altitude each cushion cap of 34 of connection is set, the column foot 1 of iron tower just is arranged on this cushion cap.
Because the foundation structure of iron tower except that bearing vertical force, also can be born the horizontal force of certain ratio, when stake exposes to the height on ground when big, this horizontal force will produce bigger moment of flexure effect in stake.Adopt existing highrise pile cap basis, its stake that exposes is for cylindrical, the cross section resistance moment is little, be unfavorable for resisting the big effect moment of flexure that the big horizontal force of iron tower produces on higher cushion cap, the quantity that needs to strengthen the cross section of shape or increase stake, cause engineering quantity to strengthen, also relatively poor for the control of basis displacement and distress in concrete simultaneously.
Summary of the invention
The high pile foundation structure of the iron tower of power transmission line that the purpose of this utility model provides that a kind of cross section resistance moment is big, engineering quantity and cost cost are little.
Technical solution of the present utility model is: a kind of high pile foundation structure of iron tower of power transmission line, it is made up of some high pilework assemblies, wherein each high pilework assembly comprises first foundation pile, second foundation pile and is used to be connected the 3rd foundation pile of column foot, and coupling beam, second shear wall and the 3rd shear wall, wherein the coupling beam two ends connect first foundation pile and second foundation pile respectively, the first shear wall two ends connect second foundation pile and the 3rd foundation pile respectively, and the second shear wall two ends connect first foundation pile and the 3rd foundation pile respectively.
High pilework assembly comprises three foundation piles, link into an integrated entity respectively by two shear walls and multiple tracks coupling beam between the foundation pile, improved the stress performance of foundation pile, improved the cross section resistance moment of whole assembly, the size of foundation pile is corresponding to be reduced, reduced engineering quantity and cost cost, can effectively improve the durability performance on basis in addition, effectively displacement of control basis and distress in concrete.
Described the 3rd foundation pile be positioned at iron leg position and other two away from the iron tower center, the bending resistance square ability on the direction that more helps improving the standard.
Describedly be higher than described first foundation pile and second foundation pile is short in the 3rd foundation pile, help saving quantity of material, strengthen the aesthetic measure on basis.
Also be provided with horizontal supporting plate in the described high pilework assembly, play reinforcement, strengthen the stable effect of shear wall.
The utility model has the advantages that: effectively improved basic cross section resistance moment, improved the stress performance of high pile foundation, can reduce engineering quantity and construction costs significantly for revealing high bigger high pile foundation, improve the durability performance of foundation structure, the ability of resisting accidental load is also promoted.

The specific embodiment
Embodiment:
Consult Fig. 2-3, high pile foundation structure for a kind of iron tower of power transmission line, it is made up of some high pilework assemblies, wherein each high pilework assembly comprises first foundation pile 5, second foundation pile 6 and the 3rd foundation pile 7 that is used to be connected column foot 1, and coupling beam 8, first shear wall 9 and second shear wall 10, wherein coupling beam 8 two ends connect first foundation pile 5 and second foundation pile 6 respectively, the two ends of first shear wall 9 connect second foundation pile 6 respectively and the 3rd foundation pile 7, the second shear walls 10 two ends connect first foundation pile 5 and the 3rd foundation pile 6 respectively.
Consult Fig. 3, in the present embodiment, column foot 1 is 4, and four the 3rd foundation piles 7 lay respectively on the column foot position at more close iron tower center, and the 3rd foundation pile 7 is higher than first foundation pile 5 and second foundation pile 6.Three foundation piles are cylindrical stake, and every six meters, a horizontal supporting plate 11 that links into an integrated entity with coupling beam 8 are set, and by concrete reinforcement structure beam slab foundation pile are connected with shear wall.
Coupling beam can be provided with twice or multiple tracks according to height of foundation, and horizontal supporting plate also can link into an integrated entity with coupling beam.
Present embodiment is compared with the highrise pile cap structure of same height, by shear wall and coupling beam are set, the quantity of foundation pile can be kept to three by four, the diameter of each foundation pile is reduced to 1.3 meters by 1.6 meters, has cancelled the structure of cushion cap in addition, reduce difficulty of construction, the base concrete amount reduces 50%, and basic steel consumption also reduces by 45%, and the integrated engineering cost can reduce about 40%, in addition, can also improve the performance of incidental loads such as shock resistance.
Above-listed detailed description is specifying at one of the utility model possible embodiments, this embodiment is not in order to limit claim of the present utility model, allly do not break away from the equivalence that the utility model does and implement or change, all should be contained in the claim of this case.
