Assembled power transmission line tower foundation

Abstract

The invention relates to the technical field of tower foundation structures, in particular to an assembled power transmission line tower foundation. The tower foundation comprises a plurality of unitassemblies, wherein the unit assemblies comprise concrete assemblies; the concrete assemblies are in a column shape or a square block structure, and at least one steel pipe assembly is arranged in each concrete assembly in an embedded mode; and the steel pipe assemblies are of tubular structures with one ends arranged in the concrete assemblies at one ends in the embedded mode and the other ends extending outwards, the steel pipe assembly is fixedly connected with steel pipe assembly on the other concrete assembly to connect the two unit assemblies into a whole, and the plurality of concrete assemblies are in butt joint with each other through the steel pipe assemblies to form the tower foundation. The assembled power transmission line tower foundation is simple in structure and convenientto assemble, the building efficiency of the tower foundation is greatly improved, the construction difficulty is reduced, the field operation time is shortened, and the workshop control of the assembly quality is facilitated; and the assembled structure is more convenient and rapid, a large amount of manpower and material resource cost is saved, and the assembled power transmission line tower foundation has great promotion values.

Description

technical field [0001] The invention relates to the technical field of pole and tower foundation structures, in particular to an assembled power transmission line pole and tower foundation. Background technique [0002] The tower foundation bears large horizontal and vertical loads, so the foundation is relatively large. The traditional cast-in-place reinforced concrete foundation has two major disadvantages: one is that the maintenance time is long, which prolongs the construction period of field work and increases the project cost; , Concrete is poured in the field, the site construction is difficult, the efficiency is low, and the quality control is difficult. In recent years, with the gradual popularization of mechanized construction of power transmission projects and the high timeliness requirements for power grid repairs after wind and ice disasters, the market demand for prefabricated foundations is increasing, but the existing foundation repair technology cannot mee...
