Description
Technical field
The utility model relates to transmission pole tower technology field, is specifically related to a kind of large-scale steel pipe Inserted Foundation.
Background technology
Traditional power transmission line iron tower foundation is generally connected with top tower body with column foot plate by pre-buried stone bolt, and when basic role power is very large, the stone bolt specification needing is often very large.For the very large large leap of basic role power, high-tension transmission overhead line structures, while adopting tradition basis, the quantity of ground foot screw, diameter and distribution circle scope thereof are all very large, thereby cause basic column width and material usage all significantly to increase, cause unnecessary waste.Conventional concrete is watered underpin, although can meet the requirement of intensity, higher at some area concrete costs.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of large-scale steel pipe Inserted Foundation is provided.
The technical solution of the utility model realizes in the following manner:
A kind of large-scale steel pipe Inserted Foundation, comprise sole plate, be arranged on the column on sole plate and insert steel tubular structure, insert steel tubular structure in column and sole plate, described insertion steel tubular structure comprises insertion steel pipe, insert steel pipe and comprise interior steel pipe and outer steel pipe, between interior steel pipe and outer steel pipe, be provided with marine sand concrete layer, and be provided with overcoat between marine sand concrete layer and outer and inner tube, in interior steel pipe, be provided with angle steel skeleton, and be filled with tube core concrete in interior steel pipe; The top of inserting steel pipe is provided with the adpting flange docking with the top main material of tower leg steel pipe, and the bottom of inserting steel pipe is provided with flange in the bottom and the location crab-bolt for solid bottom basement rock.
Described overcoat is glass fiber reinforced composite plastic layer, and carbon fiber strengthens composite plastic layer, and boron fibre strengthens any one in composite plastic layer.
The gradient of described column is consistent with the top tower leg main material gradient, and sole plate and column keep being arranged vertically, and inserts steel pipe and inserts downwards in column and sole plate along top tower leg main material direction uniform slope.
Described insertion steel pipe docks by adpting flange with the steel pipe of top tower leg main material, inserts steel pipe gradient consistent with the tower leg main material gradient; The outer wall that inserts steel pipe is welded with anchor plate.
Described angle steel skeleton is arranged in interior steel duct, and extends upwardly to certain length in the steel pipe of top tower leg main material; The vertical inclination angle of angle steel skeleton is consistent with inserting steel pipe, and angle steel skeleton four limbs keep relative fixing by junction plate with insertion steel pipe respectively.
With respect to prior art, the utility model is by directly inserting in the inclined column foundation with uniform slope by steel pipe downwards along tower leg main material direction, basic role power is directly transmitted by the squeezing action of the connectors such as the cementation between insertion steel pipe and base concrete and anchor slab, avoid using large-sized lower margin flange and bolt, form of structure is advantages of simple more, and Path of Force Transfer is clear and definite.Meanwhile, basic stand column inclination angle, due to consistent with the main material of top tower body inclination angle, is similar in circumferential stress the oblique column in basis, has greatly improved the stress of basic stand column and base plate, significantly improves basic lateral stability.In addition, steel pipe and outer steel tubular structure in this insertion steel pipe adopts, and between outer and inner tube, be provided with marine sand concrete layer, because extra large sand is compared cost with river sand and is greatly reduced, for fear of the higher extra large sand corrosion steel pipe of salt content, between marine sand concrete layer and steel pipe, be provided with overcoat, can guarantee the safety that extra large sand is used.Because each material property is adequately and reasonably applied, thereby can effectively reduce basic concrete and reinforcing bar use amount, improve the economy of power transmission line iron tower foundation.
