Prefabricated assembly type foundation structure and construction method thereof

Abstract

The invention discloses a prefabricated assembly type foundation structure and a construction method of the prefabricated assembly type foundation structure. The structure comprises a pile foundation, a center column, a top fixing part and a bottom fixing part. The pile foundation is arranged in a foundation pit. The bottom of the center column is concaved inwards to form a containing groove. The pile foundation is embedded in the containing groove. The center column comprises a first assembly portion and a second assembly portion. The top fixing part is arranged on the first assembly portion in a sleeving mode. The bottom fixing part is arranged on the foundation pit in a pressed mode. The bottom fixing part is arranged on the second assembly portion in a sleeving mode. Accordingly, the foundation construction technological steps can be greatly simplified, the construction difficulty is effectively lowered, the structural strength of the foundation is ensured under large upward pulling force or downward pressure or under soft soil layer construction conditions, then, high using reliability is ensured, and meanwhile the environmental pollution problem caused by on-site construction can be avoided.

Description

technical field

[0001] The invention relates to the technical field of substation facility construction, in particular to a prefabricated basic structure and a construction method thereof. Background technique

[0002] At present, the foundation of the domestic substation support structure mainly adopts the form of cast-in-place reinforced concrete foundation. Commonly used cast-in-place reinforced concrete foundations include independent foundation, shell foundation and pile foundation. The cast-in-place reinforced concrete foundation has the following disadvantages: it must be constructed on site, and wet work has a great impact on the environment of the construction site, which does not meet the requirements of green environmental protection; the foundation can only be used once, and the resource utilization rate is low, resulting in waste of resources. Moreover, the cast-in-situ foundation is made on-site by the construction unit, and the quality of the concrete is diffi...
