Pole tower prefabricated assembly type concrete stepped foundation and assembling method thereof

Abstract

The invention relates to a pole tower prefabricated assembly type concrete stepped foundation and belongs to the technical field of power communication transmission equipment. The pole tower prefabricated assembly type concrete stepped foundation comprises a core column, a stepped hoop and steel plate connecting keys. The core column comprises a plurality of splicing columns. The splicing columnsare of the same structure and are sequentially spliced into the core column through splicing grooves and splicing strips. The core column comprises an upper column body and a lower prismoid body fixedto the lower end of the upper column body. The stepped hoop comprises a plurality of annular sleeves with different outer diameters and inner diameters. The multiple steel plate connecting keys are mounted on the outer side of the core column and the periphery of the upper end of the stepped hoop. The steel plate connecting keys are fixed to the upper end of the stepped hoop through embedded anchors. The steel plate connecting keys are fixed to the core column through through anchor bars. The pole tower prefabricated assembly type concrete stepped foundation is ingenious in structure design,all construction projects are changed into all prefabricated modules, by splicing all the modules, the operation efficiency is improved, the construction period is shortened, and an assembling methodof the pole tower prefabricated assembly type concrete stepped foundation is simple and convenient to operate.

Description

technical field [0001] The invention relates to a tower prefabricated concrete stepped foundation and an assembling method thereof, belonging to the technical field of electric power communication transmission equipment. Background technique [0002] According to the survey data, at present, the independent foundation of the pole and tower of the distribution network project is mainly constructed by cast-in-place construction, and the cast-in-place construction often has the following shortcomings: ① In the foundation construction of the pole tower of the distribution network, the entire construction process is completed on the construction site, and the entire construction period is approximately It takes 40 days, the construction period is long, and the efficiency is low; ②The work area required for the construction is large, which seriously affects the traffic and the travel of residents. Even in some areas, the site environment cannot meet the requirements of the construc...

[0002] According to the survey data, at present, the independent foundation of distribution network towers is mainly constructed by cast-in-place construction, but the cast-in-place construction often has the following deficiencies: ①In the foundation construction of distribution network line towers, the entire construction process is completed on the construction site, and the entire construction period is about It takes 40 days, the construction period is long, and the efficiency is low; ②The construction requires a large work area, which seriously affects the traffic and residents' travel, and even the site environment in some areas cannot meet the requirements of the construction work area, and the contradiction between the government and the office is prominent; ③Subject to seasonal and big weather influence

At present, there are many sizes and division methods of prefabricated foundation modules, mainly horizontal and vertical divisions, and prefabricated foundations are generally small in size and can only bear small upper vertical and horizontal loads. The applicability of tower foundations with large overturning effects is not strong. Based on this, we propose a prefabricated concrete stepped foundation suitable for towers and its assembly method
