Abstract

The invention discloses an iron block type power tower foundation. The iron block type power tower foundation comprises a split structure main body, wherein the main body is formed by connecting a plurality of lower prefabricated iron blocks and a plurality of upper prefabricated iron blocks; a hanging part is arranged on the side surface of each lower prefabricated iron block; a hanging part is arranged at the top of each upper prefabricated iron block; a connection plate is fixed between the upper prefabricated iron blocks; a foundation short column is arranged on the connection plate; pre-buried ground anchor bolts used for fixing an upper external rod body structure are arranged on the foundation short column. The power tower foundation adopts a split prefabricated foundation, so that the weight of a single prefabricated component is reduced, the area of the single prefabricated component is reduced, and the power tower foundation is convenient to transport; the prefabrication period is shortened; the labor intensity of construction workers is greatly reduced; meanwhile, the foundation can be disassembled and repeatedly used, so that the construction cost is greatly reduced; the power tower foundation has the advantages of simple structure, convenience in mounting, low construction cost, firmness and reliability.

Description

technical field [0001] The invention relates to the technical field of power pole and tower construction, in particular to an iron block type power pole and tower foundation. Background technique [0002] The underground part of the overhead transmission line tower is collectively referred to as the foundation. The tower foundation is an important part of the overhead transmission line, and its construction period, cost and labor consumption account for a large proportion of the entire line project. According to relevant statistics: in the construction of general overhead transmission line projects, the basic construction period accounts for about half of the entire project construction period, the basic transportation volume accounts for about 60%, and the cost accounts for about 15% to 35% of the main body cost. The proportion of cost will be even higher. [0003] Concrete foundations are commonly used as foundations for pole towers. At present, the foundations are fixed ...
