Problems solved by technology

In the prior art, foundations are generally poured on site, and the foundations cast on site are based on the traditional construction process: foundation construction first, followed by tower design on the ground. Due to the use of poured-in-site foundations, the cost of the construction process is high. Long construction period and low construction efficiency

Embodiment Construction

[0026] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0027] Such as figure 1 and figure 2 As shown, they are the sectional view and elevation view of the prefabricated foundation in this embodiment respectively. The prefabricated foundation in this embodiment is a reinforced concrete structure. All the force, at the same time has the function of protecting the steel bars from corrosion; the prefabricated foundation includes the foundation base and the foundation column set on the foundation base, and the central area on the foundation base is provided with a platform, which is used to set the foundation column; along the platform The edge is provided with a downward slope outwardly.

[0028] Wherein, the foundation column is provided with a fou...

Abstract

The invention discloses a prefabricated foundation for power transmission engineering. The prefabricated foundation comprises a foundation upright post and a foundation base. The foundation upright post is arranged on the foundation base and is provided with a foundation main rib and a foundation bolt, and the upper end of the foundation bolt is exposed out of the upper surface of the foundation upright post and is used for being connected with an iron tower; and the foundation base is provided with a lifting ring, and the ring part of the lifting ring is exposed out of the upper surface of the foundation base to be connected with a crane through a connecting piece. The foundation for power transmission engineering is designed as the prefabricated foundation, so that the manufacture of a concrete foundation is completed in advance in a factory, formwork erection, casting and curing are carried out in a centralized mode, the process control and curing environment can be controlled strictly, the cost can be saved to a great extent, the quality of a foundation finished product can be improved, the curing period can be shortened by 28 days, meanwhile, the construction operation time onsite can be reduced by 80%, and personnel can be prevented from getting up and down a foundation pit; and the safety risk of personnel working in the foundation pit is avoided, the pollution of concrete to the environment is avoided, the mechanization degree of a construction site is improved, and the construction period is controllable. In addition, the prefabricated foundation is convenient totransport and install.

Description

technical field [0001] The invention relates to the technical field of electric power construction, in particular to a prefabricated foundation for power transmission projects. Background technique [0002] The traditional foundation refers to the load-bearing structure below the ground of the building, such as foundation pit, cap, frame column, ground beam, etc., which is the enlarged part of the wall or column of the building underground, and its function is to bear loads and transmit them to the foundation together with its own weight. However, in existing power transmission projects, it is also necessary to set a foundation at the bottom of the iron tower when erecting the iron tower, so that the installation of the iron tower is more stable. In the prior art, foundations are generally poured on site, and the foundations cast on site are based on the traditional construction process: foundation construction first, followed by tower design on the ground. Due to the use o...
