Embodiment Construction

[0014] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0015] Inverted airfoil foundations for transmission towers, such as figure 1 As shown, it includes a top plate 1 and several side plates 2, the sides of the top plate 1 are connected to the top of the side plates 2, wherein the top plate 1 and the side plates 2 are integrally cast. There is a cavity 3 between the top plate 1 and the side plate 2. When the inverted wing-shaped foundation of the transmission tower is buried in the underground foundation pit, the top plate 1 is on top, and the cavity 3 can be used to fill the soil. The specific internal structure of the inverted wing-shaped foundation of the transmission tower is as follows: figur...

Abstract

The invention discloses an inverted wing-shaped foundation of a power transmission tower. The inverted wing-shaped foundation is characterized by comprising a top plate and a plurality of side plates, wherein the top plate and the side plates are integrally cast; side edges of the top plate are connected with the tops of the side plates; a cavity for filling soil is formed between the top plate and the side plates; the top plate is provided with a plurality of transverse top plate main bars; the top plate main bars extend to the bottoms of the side plates connected with the two ends of the top plate main bars; the top plate is provided with a plurality of longitudinal top plate stirrups; the top plate stirrups extend to the bottom of the side plates connected with the two ends of the top plate stirrups; the side plates are provided with a plurality of transverse side plate main bars. Compared with the conventional excavation foundation, since the top plate main bars, the top plate stirrups and the side plate main bars are of a staggered structure, the inverted wing-shaped foundation has better slip resistance and anti-overturning performance and can effectively resist the action of transverse load; the inverted wing-shaped foundation has a concise structure and is convenient to construct and clear in force transmission, and the engineering workload of the foundation can be reduced to achieve a purpose of saving the resource.

Description

technical field [0001] The invention relates to a foundation, in particular to an inverted wing-shaped foundation for a power transmission tower. Background technique [0002] The foundation is a load-bearing component that is in contact with the foundation at the bottom of the building. Its function is to transfer the load from the upper part of the building to the foundation. It is an important part of houses, bridges, docks and other structures. The transmission tower is a tall structure with a huge amount of engineering and is very important. As a power facility of an important lifeline project, the transmission tower transmits the load to the foundation through the foundation. No matter which part of the foundation or foundation is faulty or damaged, it will have a bad impact on the upper transmission tower or even cause a major accident. Due to the complexity of the foundation conditions and the particularity of the physical and mechanical properties of the soil, peop...
