Abstract
The utility model discloses a cross shaped foundation of a transmission line iron tower, which comprises a main post, wherein the middle of the main post is provided with a side baffle plate. In the utility model adopting the technical scheme, the side baffle plate is arranged on the main post, overturning moment generated by a horizontal force can be counteracted by using an earth resistance of undisturbed soil on the side, thus the eccentric stress of the bottom of the foundation and the bending moment of the post body of the foundation are reduced, and the side stability and the bearing capacity of the foundation are improved. A cantilever of the foundation can be longer, thus the overturning resisting property of the foundation can be remarkably improved. When the foundation exposes a little, material consumptions of the crossed shaped foundation and a dug foundation are equivalent and the comprehensive construction costs are smart different. With the increase of the exposing part of the foundation, the concrete consumption of the cross shaped foundation is remarkably reduced, and compared with the dug foundation, the concrete can be saved by about 10 percent every foundation, thus the comprehensive construction cost is remarkably lowered. The utility model has better economic benefit.
Description
Technical field
The utility model relates to a kind of basis of iron tower of power transmission line, specifically relates to a kind of cross iron tower of power transmission line basis.
Background technology
In the mountain area, areas such as hills and Long Gang, circuit does not wait being used of higher baseline and iron tower unequal leg for adopting, and often basic principal post need be increased.Along with increasing of basic principal post, the lateral stability on basis just becomes the governing factor of digging foundation, for satisfying the requirement of overturning stability, often need increase embedded depth of foundation and principal post diameter, causes amount of concrete to increase greatly, as shown in Figure 1.
Summary of the invention
The purpose of this utility model provides a kind of cross basis of transmission line of electricity, and it can reduce the eccentric stress of the moment of flexure and the foundation bottom of basic shaft, improves the lateral stability and the supporting capacity on basis.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises principal post, in the middle and upper part of described principal post the side direction baffle plate is set.
Described principal post is provided with the side direction baffle plate is vertical.
Adopt the utility model of technique scheme, on principal post, be provided with the side direction baffle plate, utilize the earth resistance of side undisturbed soil, the overturning moment that offset by the level of power produces, thereby reduced the eccentric stress of the moment of flexure and the foundation bottom of basic shaft, improved basic lateral stability and supporting capacity.The basis cantilever can be longer, can significantly improve the overturning or slip resistance analysis performance on basis.Under the less situation of appearing on the basis, cross basis with draw that to dig formula basic material consumption suitable, comprehensive cost is more or less the same.Along with increasing of appearing in the basis, the amount of concrete on cross basis significantly reduces, and compares with digging foundation, and it is about 10% that every base can be saved concrete, obviously reduces comprehensive cost, has better economic.
Description of drawings
Fig. 1 is traditional iron tower of power transmission line basis.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 2, the utility model comprises principal post 1, and at the middle part of principal post 1 side direction baffle plate 2 is set, and principal post 1 and the side direction baffle plate 2 vertical preferred forms that are set to.
When construction, can adopt the mode of drawing the type of scraping out that side direction baffle plate 2 is processed.Position that side direction baffle plate 2 is provided with and size can be determined according to calculating and actual needs.Draw the form of construction work extensive use in the line tower foundation construction of the type of scraping out, personal safety is secure, easy construction, the excavation face is little, has reduced compensation for crops usefulness, and labour intensity is low, made full use of the good advantage of original state foundation soil load-carrying properties, and reduced vegetation deterioration, avoided soil erosion, be beneficial to environmental protection.
This fundamental mode foundation ditch is applicable to no underground water, can draws all kinds of grounds of the type of scraping out.This fundamental mode still adopts the job practices of drawing the type of scraping out, also just kept and drawn every advantage of digging the formula basis, and dig at drawing that the formula foundation load strengthens, lateral stability can not satisfy the characteristics of overturning stability when principal post was increased, the side direction baffle plate is set, utilize the earth resistance of side undisturbed soil, the overturning moment that offset by the level of power produces, thus the eccentric stress of the moment of flexure and the foundation bottom of basic shaft reduced, improved basic lateral stability and supporting capacity.The basis cantilever can be longer, can significantly improve the overturning or slip resistance analysis performance on basis.
Under appear less situation on the basis, cross basis with draw that to dig formula basic material consumption suitable, comprehensive cost is more or less the same.Along with increasing of appearing in the basis, the amount of concrete on cross basis significantly reduces, and compares with digging foundation, and it is about 10% that every base can be saved concrete, obviously reduces comprehensive cost, has better economic.
