Abstract

The invention provides a guide frame fixing construction method, and belongs to the technical field of guide frames. According to the fixing construction method, fixing is achieved through a lifting pile leg carried by the guide frame, the lifting of the pile leg mainly depends on mechanical driving, the fixing mode is simple and convenient, and the structure is stable. The guide frame fixing construction method comprises the following steps that the guide frame is accurately transported in place through positioning; the pile leg is lowered for multiple times through a lifting driving device until the pile leg is inserted into a water sediment layer; a platform is driven by the lifting driving device to climb along the pile leg multiple times until the platform is not affected by buoyancy,and in the climbing process of the platform, the pile leg is further pressed into the water sediment layer under the action of the gravity of the platform until stability is achieved; and the platform is driven by the lifting driving device to descend multiple times along the pile leg until reaching the platform using position.

Description

technical field [0001] The invention belongs to the technical field of guide frames, and in particular relates to a construction method for fixing guide frames. Background technique [0002] At present, in the construction of wind power pile foundation, the crane ship is often used to cooperate with the guide frame to carry out pile sinking. The guide frame usually needs to be fixed by setting up fixed piles. However, this fixing method is more cumbersome and requires higher construction requirements . [0003] In the field of offshore platform technology, in order to facilitate the fixing of offshore platforms, a self-elevating platform with lifting legs has been developed. The pin type hydraulic lifting system mainly relies on the hydraulic cylinder to realize the lifting drive. However, there is also a problem of instability in the lifting drive by hydraulic pressure. [0004] Therefore, how to provide a simple and stable way to fix the guide frame is a technical probl...
