Description

Technical Field

[0001] The utility model relates to the technical field of electric wire tower installation, in particular to an assembled foundation of a collector line tower. Background Art

[0002] With the development of green and low-carbon economy currently advocated, new energy is developing rapidly. With the increase in the number of new energy projects, the length of overhead collection lines built to support new energy projects is getting longer and longer, and the corresponding overhead collection line tower foundations are also increasing.

[0003] The overhead collector line is long, and the construction location of the tower foundation supporting the conductor is scattered. The foundation usually adopts a concrete foundation. The collector lines of new energy projects are usually located in remote areas, and it is inconvenient to mix concrete on site and transport commercial concrete. For overhead collector lines, the conductors are supported on the tower, and the tower is supported on the concrete foundation. Under the action of the tension wire, the tower legs will generate an upward pull force, which is transmitted to the foundation. The foundation often needs to resist pullout. In areas with poor geological conditions, pile foundations are required. The foundation of the conventional overhead collector line tower adopts a cast-in-place reinforced concrete slab foundation. The site requires formwork support, reinforcement, and concrete pouring. Most of these links are completed manually, and the construction progress is slow. The foundation of the overhead collector line is generally excavated mechanically. When a cast-in-place reinforced concrete foundation is used, due to the slow construction speed, when it encounters the rainy season, rainwater will accumulate in the foundation pit, causing disturbance to the foundation soil, making construction difficult and affecting the construction period. In addition, there are wet operations on the construction site, and the level of civilized construction on site is not high, which has a great impact on the environment. The use of cast-in-place reinforced concrete foundations, due to the scattered location of the foundations, it is difficult for the concrete mixed on site to achieve high strength, and the foundation size is relatively large, which increases the amount of reinforced concrete materials used, indirectly increasing energy consumption. At the same time, due to progress reasons, when winter construction is required, cast-in-place reinforced concrete structures are used, which have high requirements for ambient temperature. When the temperature is below a certain level, winter construction measures need to be adopted, and the construction cost is high. In addition, it is inconvenient to construct, the construction progress is slow, and the construction difficulty is high. It can be seen that the use of cast-in-place reinforced concrete foundations will consume a large amount of reinforced concrete materials and labor costs due to the large number of overhead collector line tower foundations and their scattered locations. The construction is difficult and slow, and the project cost is high. Therefore, a prefabricated foundation for collector line towers is proposed to solve the above problems. Utility Model Content

[0007] As a further solution of the utility model: the prefabricated foundation plate includes prefabricated foundation short column longitudinal reinforcement and prefabricated foundation short column stirrups, and the prefabricated foundation short column longitudinal reinforcement and the prefabricated foundation short column stirrups are fixed by steel wire binding. The prefabricated foundation is formed by placing the bracket bound between the prefabricated foundation short column longitudinal reinforcement and the prefabricated foundation short column stirrups into the template, and holes and installation grooves are reserved at the same time, and then the molded concrete is poured in and out.

[0026] The prefabricated foundation plate 2 includes prefabricated foundation short column longitudinal reinforcement 13 and prefabricated foundation short column stirrups 14, which are fixed by steel wire bundling. The prefabricated foundation is formed by placing the bracket bundled between the prefabricated foundation short column longitudinal reinforcement 13 and the prefabricated foundation short column stirrups 14 into the template, and reserving holes 6 and installation grooves 15, and then pouring and molding concrete 20 to form the prefabricated foundation.
