Embodiment Construction

[0013] Such as Figure 1-2 As shown, the transmission pole tower-type single-cable foundation structure in the embodiment of the present invention includes an upper plate 1 laid on the ground surface and a lower plate 2 buried underground, and the upper plate 1 and the lower plate 2 are connected by a steel strand The rope 3 is connected, and the steel strand rope 3 between the upper plate 1 and the lower plate 2 is provided with a rubber sleeve 4 outside, and the two ends of the rubber sleeve 4 are in contact with the upper plate 1 and the lower plate 2 respectively. The inside of the rubber casing 4 is filled with anti-corrosion filler 5; the two ends of the steel strand 3 are respectively provided with an anchor head 61, 62, and an upper bearing pad is provided between the upper anchor head 61 and the upper plate 1 71. A lower bearing base plate 72 is provided between the lower anchor head 62 and the lower plate 2; the upper bearing base plate 71 is poured with four symmetr...

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 [0001] The invention relates to a power transmission pole and tower equipment, specifically a foundation fixing structure for a power transmission pole and tower. Background technique [0002] In large-thickness loess areas, the foundations of pole towers mainly adopt "big excavation" foundations, digging and bottom expansion foundations, and explosive expansion pile foundations. "Large excavation" foundation category refers to the foundation buried in the pre-excavated foundation pit and the backfill soil is compacted. It uses the disturbed backfill soil to form an uplift-resistant soil body to maintain the uplift stability of the foundation. Excavated and expanded bottom foundation refers to the foundation that is filled with concrete and steel skeleton in the soil tire excavated by machinery or manually. It maintains the uplift and stability of the foundation with the naturally formed uplift-resistant soil. Explosive expansion pile foundation refers to th...
