Abstract

The invention discloses a prefabricated light GFRP octagonal cable well. The prefabricated light GFRP octagonal cable well comprises a cover plate, stand columns, a cover plate support, baffles, inverted-T-shaped cross beams and a bottom plate, wherein the eight inverted-T-shaped cross beams are fixed to the bottom plate and arranged in a regular octagon shape; the stand columns are arranged between every two adjacent inverted-T-shaped cross beams, and grooves of the stand columns are tightly matched with the inverted-T-shaped cross beams; the baffles are arranged between every two adjacent stand columns, the bottom ends of the baffles are connected and fixed to the inverted-T-shaped cross beams through rabbets, and the top ends of the baffles are connected and fixed to the cover plate support through rabbets; and the cover plate is fixed to the cover plate support through bolts. According to the prefabricated light GFRP octagonal cable well, by adopting a light GFRP material and a prefabricated assembly mode, the requirements for structural bearing and using functions are met, and the weight of the prefabricated light GFRP octagonal cable well is only 1 / 3 1 / 2 of the weight of a traditional concrete cable well with the same size; and meanwhile, the construction efficiency is improved by 50% or above compared with that of the traditional concrete cable well, and the prefabricated light GFRP octagonal cable well has the characteristics of being economical, reasonable, convenient to transport and convenient and fast to construct.

Description

technical field [0001] The invention relates to the technical field of electric power construction, in particular to a prefabricated light-weight GFRP octagonal cable shaft and a construction method thereof. Background technique [0002] In order to facilitate the pulling of cables on straight sections at corners and branches of transmission lines, cable wells need to be set up. The commonly used cast-in-place reinforced concrete octagonal cable wells in the prior art are built by on-site formwork, tying steel bars, and pouring concrete. The construction period is long, the construction period is obviously affected by the climate, the construction quality fluctuates greatly, and the degree of mechanization is low. , high labor intensity for workers, difficult project management, and not conducive to environmental protection; while the prefabricated reinforced concrete octagonal cable shaft has the disadvantages of excessive overall weight, difficult lifting and transportatio...
