Detailed description of the invention
For making the technical solution of the utility model and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
A kind of transmission line of electricity hollow slab type pole and tower foundation, see Fig. 1, and composition graphs 2 and Fig. 3, described hollow slab type pole and tower foundation comprises:
Base 2, described base 2 inside is provided with hollow hole 201;
Basis principal post 1, described basic principal post 1 is connected with base 2, and described basic principal post 1 is solid cylinder;
Link 3, described link 3 is positioned at the top of described basic principal post 1, for being connected with electric power line pole tower by described pole and tower foundation;
Reinforcing cage is embedded with in described basic principal post 1 and base 2.
The operating principle of the hollow slab type pole and tower foundation that the utility model embodiment provides is: basic principal post 1 is connected by being positioned at the two inner reinforcing cage 4 with base 2.Link 3 is connected with the footing piece of electric power line pole tower, thus is connected with shaft tower by described hollow slab type pole and tower foundation.
The structure of the utility model embodiment to existing transmission line tower foundation is optimized improvement, by arranging hollow hole 201 in base 2 inside, obtains a kind of hollow slab type pole and tower foundation.The hollow slab type pole and tower foundation that the utility model embodiment provides, under the prerequisite ensureing pole and tower foundation intensity, can reduce concrete and the amount of reinforcement of pole and tower foundation, reduces costs.Compared with traditional solid hopkinson bar tower foundation, the hollow slab type pole and tower foundation that the utility model embodiment provides can save concrete 17 ~ 35%, can save reinforcing bar 10 ~ 20%, remarkable in economical benefits.
In above-mentioned hollow slab type pole and tower foundation, the shape of hollow hole 201, size, quantity and the distribution in base 2 inside all do not have strict restriction.The load that those skilled in the art can bear according to the shape of base, pole and tower foundation etc. design the shape of hollow hole 201, size, quantity and the distribution in base 2 inside.See Fig. 4 and Fig. 5, in order to clearer expression hollow hole 201, Fig. 4 and Fig. 5 to illustrate the structure of hollow hole 201 from a cross section of base 2.The shape of hollow hole 201 cross section can be the circle shown in Fig. 4, also can be square shown in Fig. 5, can also be oval or the polygon such as triangle, pentagon, hexagon, octagon.Hollow hole 201 can be uniformly distributed in base 2, also can uneven distribution.
In above-mentioned hollow slab type pole and tower foundation, there is no strict restriction, this area routine techniques means in the method for base 2 inside processing hollow hole 201.Such as, can before concreting, pre-buried thin-walled capsula interna (because the external surface of thin-walled capsula interna overlaps with the inner surface of hollow hole 201, therefore not illustrating in the drawings), then carry out the method for concreting.For the formation of the thin-walled capsula interna of hollow cavity in the utility model embodiment, be made mainly with Light rubber gel material, reinforcing material etc., external diameter can need to get 100mm ~ 500mm according to structure stress and structure, and length is determined according to sole plate width calculation; The specification of thin-walled capsula interna, material, the index such as physical and mechanical property and chloride content, before not putting into effect this area industry standard requirement, the relevant regulations of " cast-in-place concrete hollow building roof obturator " (JC/T952-2014) and the requirement of corresponding product standard should be met.The shape of the hollow hole 201 obtained according to above-mentioned requirements, size, quantity and distribution are just determined by the shape of thin-walled capsula interna, size, quantity and distribution.Therefore, the shape of hollow hole 201, size, quantity and distribution can be controlled by selecting suitable thin-walled capsula interna.After pole and tower foundation is shaping, do not need thin-walled capsula interna to remove.
In above-mentioned hollow slab type pole and tower foundation, described base 2 can be the staged base shown in Fig. 1, also can be the ramp type base shown in Fig. 8.When described base 2 is staged base, the progression of step includes but not limited to 2 grades.If adopt 1 grade of step, then base 2 is cuboid or square.When step progression is more than 2 grades, hollow hole 201 can be all set in the inside of every one-level step, also only hollow hole 201 can be set in the inside of certain one-level or what step.Every grade of step can arrange the hollow hole 201 of same shape and size, also can arrange the hollow hole 201 of difformity or different size.But from the viewpoint of convenience and the cost etc. of construction, preferably every grade of step arranges the hollow hole 201 of same shape and size.When sole plate is 2 grades and above quantity step and every grade of step is provided with hollow hole 201, hollow hole 201 can be mutually perpendicular direction (as shown in Figure 4, Figure 5) at the distribution arrangement of adjacent step, also can be same direction (as shown in Figure 6), preferably arrange hollow hole 201 with mutually perpendicular direction from structure stress angle.When will work as described base 2 for ramp type base, the angle of inclined-plane and horizontal plane will not have strict restriction, and those skilled in the art can be arranged voluntarily according to actual conditions.
In above-mentioned hollow slab type pole and tower foundation, the axis of described basic principal post 1 can for vertical direction (as shown in Figure 1) also can and vertical direction between there is certain angle (as shown in Figure 7).When the axis of basic principal post 1 and vertical direction have angle, its angle, generally at 5 ~ 15 °, specifically can be determined according to top steel tower structure.
In above-mentioned hollow slab type pole and tower foundation, the shape of the cross section of described basic principal post 1 does not have strict restriction, such as, can be the shape such as circular, square.
In above-mentioned hollow slab type pole and tower foundation, basic principal post 1 and base 2 can for building the basic principal post and base that are molded as one, the basic principal post that also then can be assembled into one for processing and manufacturing respectively and base.
Difform basic principal post 1 and base 2 can combine arbitrarily.Such as, in Fig. 1, base 2 is staged base, basic principal post 1 for cross section be square and the cylinder of axis vertical; In Fig. 7, base 2 is staged base, and basic principal post 1 is square and axis and vertical direction have the cylinder of angle for cross section; In Fig. 8, base 2 is ramp type base, basic principal post 1 for cross section be square and the cylinder of axis vertical; In Fig. 9, base 2 is ramp type base, and basic principal post 1 is square and axis and vertical direction have the cylinder of angle for cross section.
In above-mentioned hollow slab type pole and tower foundation, the concrete structure of described link 3 does not have considered critical, as long as pole and tower foundation and shaft tower can be linked together, such as, can be stone bolt or plug-in type angle iron.The strict restriction that the quantity of link 3 and the distribution on basic principal post 1 do not have, those skilled in the art can determine according to actual condition.
The hollow slab type pole and tower foundation of the utility model embodiment can be built at the construction field (site), also can prefabricated after install at the construction field (site), improve efficiency of construction.
The above is only understand the technical solution of the utility model for the ease of those skilled in the art, not in order to limit the utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
