specific Embodiment approach

[0030] Various types of self-supporting towers, steel pipe poles, cement poles and cables with cables are widely used in line sections where vehicles and machinery frequently pass by within 15 meters of the outer edge of various tower foundations. They are mainly used for transmission line towers and cable collision piers The finished product is manufactured and poured on site to replace the currently widely used simple concrete pouring and brick-built collision-free buffer strips, resistance piers, pole towers and pull-wire crash piers. The finished product size is processed and poured on site. After rigid body impact, mitigation and stability calculations, it can meet the requirements. Therefore, the anti-impact warning wall, anti-collision buffer belt, and resistance pier are suitable for 10-1100KV voltage level UHV to low voltage various towers Type and cable anti-collision measures, warning, anti-collision buffer absorption rigid belt, resistance pier is safe, economical a...

Abstract

The invention relates to a buffer type tower and stay wire crash bearer, and belongs to an electric power facility. The buffer type tower and stay wire crash bearer comprises a line tower, and is characterized by further comprising a buffering pier and a resistance pier, wherein the buffering pier is in a sandwich-type structure; and the resistance pier is fixedly arranged on one side, close to the line tower, of the buffering pier. The tower and stay wire crash bearer adopts a finished product production assembling pattern and in-situ cast, is in cuboid or cylindrical structural forms, and can change with a tower type and a stay wire; according to the tower and stay wire crash bearer of each tower, initial passing impact force and buffering damp can be worked out conveniently according to different borne rigid force and foundations; a construction period can be shortened greatly; and the facility of a power transmission line is prevented from being impacted accidentally.

Description

technical field [0001] The invention relates to a buffer type pole tower and a pull-line anti-collision pier, belonging to electric power facilities. Background technique [0002] According to Article 36 of the "Implementation Rules for the Protection of Electric Power Facilities of the State Grid Corporation of China", the measures to prevent the damage of construction vehicles (machines): the line sections where vehicles and machinery frequently pass within 15 meters of the outer edge of the tower foundation should be eliminated. Strengthening measures for coupling beams are added to the foundation, and auxiliary measures such as brick sand-filled piers, energy-dissipating anti-collision buckets, rubber retaining rings, and walls are used to mitigate the impact. Anti-collision measures should be taken for the cables that are vulnerable to impact, and conspicuous warning signs should be set up. [0003] 6.1.3.6 of "State Grid Corporation's Eighteen Major Power Grid Anti-Ac...
