Abstract
The invention discloses a transmission tower plate-type single rope foundation structure which comprises an upper plate which is paved on the ground surface and a lower plate which is buried under the ground, wherein the upper plate and the lower plate are connected through a steel twisted rope; a rubber sleeve is arranged outside the steel twisted rope between the upper plate and the lower plate; anticorrosion fillers are filled inside the rubber sleeve; anchor heads are respectively arranged at the two ends of the steel twisted rope; an upper bearing base plate is arranged between the anchor head at the upper part and the upper plate; a lower bearing base plate is arranged between the anchor head at the lower part and the lower plate; and four foundation bolts which are arranged in symmetry are cast on the upper bearing base plate. The transmission tower plate-type single rope foundation structure provided by the invention has the advantages that force transmission boundary conditions are complete and clear, physical mechanical properties of various materials are brought into full play, the investment is saved, the safety and the reliability are high, the construction is simple and convenient, and the like; and therefore, the foundation is applicable to loess regions with large up-pull forces and poor physical mechanical properties of the foundation earth, such as line foundations of voltage grades less than 110kV.
Description
Technical field
The present invention is a kind of transmission tower equipment, specifically the basic fixed structure of transmission tower.
Background technology
At large thickness Canal in Loess Area, pole and tower foundation mainly adopts " heavy excavation " foundation class, draws and dig spread foundation class, explosion expanded piling foundation class basis." heavy excavation " foundation class means and is embedded in the foundation ditch that digs in advance and with the basis of backfill compacting, it be backfill with disturbance consist of the resistance to plucking soil body keep the basis on pull out stable.Draw and dig the spread foundation class and mean with concrete and cage of reinforcement and be poured into machinery or manually draw basis in the native tire that scrapes out, it be the resistance to plucking soil body with natural formation keep the basis on pull out stable.The explosion expanded piling foundation class means with concrete and cage of reinforcement and is poured into the stub of the bellend in the native tire of explosive expansion moulding basis that its resistance to plucking soil body is substantially close to intact natural soil.
The key dimension of " heavy excavation " foundation class determines by its resistance to plucking stability the subject of knowledge and the object of knowledge, in order to pull out the requirement of stability on satisfying, must strengthen key dimension, has improved foundation cost, because spoir is more, environmental disruption is also larger simultaneously.Draw and dig in the cohesive soil that the spread foundation class is suitable for anhydrous infiltration foundation ditch, the pile foundation regulation and stipulation adopts pile foundation such as the basis simultaneously, and essential bearing stratum need pass collapsible loess, so this basis is not suitable for large thickness Collapsible Loess District.The large and technique of explosion expanded piling foundation class difficulty of construction and dimensional gaughing have certain difficulty.
Summary of the invention
In order to address the above problem, the invention provides a kind of board-like single rope foundation structure of transmission tower that is applicable to large thick Canal in Loess Area.
Purpose of the present invention is come specific implementation by the following technical programs:
The board-like single rope foundation structure of transmission tower, comprise that a upper plate that is laid on the earth's surface and one are embedded in underground lower plate, connect by steel strand rope between described upper plate and the lower plate, described steel strand rope outside between upper plate and lower plate is provided with the gum cover pipe, the two ends of described gum cover pipe contact with lower plate with upper plate respectively, are filled with anticorrosive packing in described gum cover pipe inside; The two ends of described steel strand rope are respectively equipped with an anchor head, are provided with the carrying backing plate between the anchor head on top and the upper plate, are provided with lower carrying backing plate between the anchor head of bottom and the lower plate; Described upper carrying backing plate upper has four stone bolt that are arranged symmetrically with.Described upper plate, lower plate are the Reinforced Concrete Materials moulding by casting.
Described upper plate adopts rectangular structure, and the area of upper plate is much larger than the area of lower plate.
The board-like single rope foundation structure of transmission tower provided by the invention; upper plate uses as the foundation to protect cap; having the power transmission fringe conditions improves distinct; give full play to the physical and mechanical property of various materials; save investment, the advantages such as safety reliability height and easy construction, it is less to be applicable to uplift force; the foundation soil physico-mechanical properties is Canal in Loess Area preferably, such as the following electric pressure line tower foundation of 110kV mechanism.
This foundation structure is flexible foundation, adopts this foundation structure can improve the ability of shaft tower opposing dynamic load; Simultaneously can reduce the spoir amount, preserve the ecological environment; And convenient disassembly, do not re-use such as this basis, steel strand directly can be cut off, excavate upper plate and get final product, reduced basic projects amount; And the double ground wire of doing of Load Transfer mechanism can be used.This foundation structure Load Transfer is clear and definite, and structural calculation and construction are easier.
