Abstract

The invention provides a tower foundation and a foundation module thereof. The tower foundation comprises a foundation body and a plurality of sets of first prestressed steel strands; a first cavity and a second cavity are formed in the middle of the foundation body; the first cavity communicates with the second cavity, and the first cavity penetrates through the top of the foundation body; the multiple sets of first prestressed steel strands penetrate through the foundation body and are arranged on the peripheral side of the first cavity in the circumferential direction of the foundation body; and the first ends of the first prestressed steel strands are anchored to the top surface of the foundation body, and the second ends of the first prestressed steel strands are anchored to the inner wall surface of the second cavity. Thus, when the first prestressed steel strands need to be replaced, the covering soil above the foundation body is excavated, the first prestressed steel strands are replaced by a new one, then prestressed tension is performed to complete replacement, the foundation body does not need to be chiseled, the safety problem can be avoided, the construction period is shortened, the field technological process is simplified, and the engineering cost and the labor force are saved.

Description

technical field [0001] The present application relates to the technical field of civil engineering, in particular to a tower foundation and a foundation module thereof. Background technique [0002] The tower foundation can be applied in many different occasions to provide support, for example, it can be applied in the derrick for drilling, or it can also be applied in the tower of the wind power generator. In related technologies, prestressed anchor bolts are mostly used in onshore wind farms as the connection method between the tower and the foundation of the wind power generating set. However, once this prestressed anchor bolt is broken, it is difficult to replace. It is necessary to cut open the basic body, remove the broken prestressed anchor bolt, reinstall a new prestressed anchor bolt, and finally repair the basic body. This method is time-consuming and laborious, and there are security problems. Contents of the invention [0003] In order to overcome the problem...
