Abstract
The invention discloses an independent foundation of a power transmission tower. The independent foundation is characterized by comprising a bottom plate, a buffer plate and a stand column, wherein the bottom plate, the buffer plate and the stand column are integrally cast; the buffer plate is arranged on the bottom plate to enhance the shearing resistance of the stand column; the stand column penetrates the bottom plate and the buffer plate; both the bottom plate and the buffer plate are provided with a plurality of transverse bottom plate main bars and a plurality of longitudinal bottom plate stirrups; the stand column is provided with a plurality of longitudinal stand column main bars and a plurality of transverse stand column stirrups; the top of the stand column is provided with foundation bolts for fixing equipment. According to the conventional single foundation under column, the stand column is only in contact with the bottom plate; according to the independent foundation of the power transmission tower, since the buffer plate is additionally arranged, the contact area of the stand column and the buffer plate is increased; thus, the independent foundation of the power transmission tower has better shearing resistance and a concise overall structure, is convenient to construct and clear in force transmission and can effectively resist the transverse load.
Description
Technical field
The present invention relates to a kind of basis, relate in particular to a kind of power transmission tower single footing.
Background technology
Basis is the supporting member that construction bottom contacts with ground, and its effect is that the load on building top is passed to ground, is the important component part of house, bridge, harbour and other structure.Power transmission tower is the tall and slender structure that a kind of engineering quantity is huge and very important.As the electric power facility of important lifeline engineering, power transmission tower is to transfer the load in ground and go by basis, and no matter which partly goes wrong or failure ground or basis, all will make a very bad impression and even cause a serious accident the top power transmission tower.Complexity due to foundation condition, the particularity of the physico-mechanical properties of soil, people are also exploring and are going deep into its understanding so far, therefore, the design on basis occupies very consequence in the super-pressure Design Transmission Line, and the selection of basic pattern is to affect one of Engineering Overall cost principal element.The selection of basis pattern, should be determined in conjunction with each section landform, hydrogeological situation, execution conditions and power transmission tower pattern, and should be under the prerequisite that meets rules, standard, the reduce construction costs.
Summary of the invention
The object of the present invention is to provide a kind of simple for structure, save material, easy construction, power transmission tower single footing that shear behavior is good.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions: the power transmission tower single footing, it is characterized in that, the base plate, buffer board and the column that comprise the one cast molding, described buffer board is arranged on the shear behavior that strengthens column on base plate, and described column runs through base plate and buffer board; Be provided with some transverse bottom plate master muscle and some vertical base plate stirrups on described base plate and buffer board, described column is provided with some vertical column master muscle and some transverse upright stirrups, and described column top is provided with the stone bolt of fixed equipment.
Traditional independent foundation under column, column only contacts with base plate, and power transmission tower of the present invention single footing is owing to having increased buffer board, increased the contact area of column and buffer board, thereby make power transmission tower single footing shear behavior better, and terminal with compact integral structure, easy construction, power transmission are clear and definite, can effectively resist transverse load.
Further, the length of described buffer board be floor length 1/3rd to 2/3rds between, described buffer board is positioned at the center of base plate, described column runs through the center of base plate and buffer board.The length of buffer board and highly can selecting according to actual conditions, because the length than base plate is short, can reach higher shear-carrying capacity with less material, reach the purpose of saving resource.
The invention has the beneficial effects as follows: power transmission tower single footing shear behavior is better, and terminal with compact integral structure, easy construction, power transmission are clear and definite, effectively saving resource resist transverse load.
The accompanying drawing explanation
The sectional view that Fig. 1 is power transmission tower of the present invention single footing;
The top view that Fig. 2 is power transmission tower of the present invention single footing;
The mark implication of accompanying drawing is as follows:
1: base plate; 2: column; 3: column master muscle; 4: the column stirrup; 5: stone bolt; 6: buffer board; 7: ground; 8: base plate master muscle; 9: the base plate stirrup.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention is described in further detail, can be implemented so that those skilled in the art can better understand the present invention also, but illustrated embodiment is not as a limitation of the invention.
The power transmission tower single footing, as shown in Figure 1, comprise base plate 1, buffer board 6 and column 2, and wherein buffer board 6 is arranged on base plate 1, for increasing vertical contact area of column 2, and then the shear behavior of enhancing column 2.Base plate 1, buffer board 6 and column 2 are one cast moldings, and column 2 runs through base plate 1 and buffer board 6, and during use, the bottom of column 2 directly is placed in foundation ditch.Be provided with some transverse bottom plate master muscle 8 and some vertical base plate stirrups 9 on base plate 1 and buffer board 6, as shown in Figure 2, succinct for picture only illustrated part base plate master muscle 8 and base plate stirrup 9 on base plate 1.Be provided with some vertical column master muscle 3 and some transverse upright stirrups 4 on column 2, as shown in Figure 1.By main muscle and the stirrup be crisscross arranged, guaranteed the strength and stability performance of single footing.Column 2 tops are provided with the stone bolt 5 of fixed equipment, and equipment is fixed on the power transmission tower single footing by stone bolt 5.
Preferably the length of buffer board 6 be base plate 1 length 1/3rd to 2/3rds between, buffer board 6 is positioned at the center of base plate 1, column 2 runs through the center of base plate 1 and buffer board 6.The length of buffer board 6 and highly can selecting according to actual conditions, because the length than base plate 1 is short, can reach higher shear-carrying capacity with less material, reach the purpose of saving resource.
During use, the top of column 2 is exposed on ground 7, and remainder is in the foundation ditch be embedded under ground 7.Traditional independent foundation under column, column 2 only contacts with base plate 1, and power transmission tower of the present invention single footing is owing to having increased buffer board 6, increased the contact area of column 2 with buffer board 6, thereby make power transmission tower single footing shear behavior better, and terminal with compact integral structure, easy construction, power transmission are clear and definite, can effectively resist transverse load.
These are only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes manual of the present invention and accompanying drawing content to do; perhaps directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
