Embodiment Construction

[0013] Such as Figure 1-2 As shown, the transmission pole tower-type three-cable foundation structure described in the embodiment of the present invention includes an upper slab 1 laid on the ground surface and three lower slabs 2 buried in the ground, between the upper slab 1 and each lower slab 2 Respectively connected by a steel strand rope 3, the three lower plates 2 are set in a straight line, the length of the steel strand rope 3 in the middle is greater than the length of the steel strand rope 3 on both sides, and the steel strand ropes on both sides 3 are equal in length, and each steel strand 3 between the upper plate 1 and the lower plate 2 is provided with a rubber sleeve 4, and each of the two ends of the rubber sleeve 4 is connected with the upper plate 1 and the lower plate 2 respectively. A lower plate 2 is in contact, and the inside of the rubber sleeve 4 is filled with anti-corrosion filler 5; the two ends of the steel strand 3 are respectively provided with ...

Abstract

The invention discloses a transmission tower plate-type three-rope foundation structure which comprises an upper plate which is paved on the ground surface and three lower plates which are buried under the ground. The transmission tower plate-type three-rope foundation structure is characterized in that the upper plate and each of the lower plates are respectively connected through a steel twisted rope; the three lower plates are arranged in a transverse straight line manner; the length of the steel twisted rope at the middle part is larger than the lengths of the steel twisted ropes at two sides; and the lengths of the steel twisted ropes at two sides are equal. According to the transmission tower plate-type three-rope foundation structure provided by the invention model, the upper plate is used as a foundation protecting cap and 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 grade are high, the construction is simple and convenient, and the like; when the line foundation earth is poor in physical mechanical property and the up-pull load is large, the security and the reliability of the foundation are greatly improved as three anchor ropes are adopted; and therefore, the foundation structure is applicable to loess regions with large up-pull forces and poor physical mechanical properties of the foundation earth, for example, line foundations of voltage grades more than 330kV.

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...
