Split type hoisting method for 5MW land type wind generating set
ActiveCN105000462AReduce single lifting weightReduced mechanical lifting performance requirementsLoad-engaging elementsGravity centerEngineering
The invention discloses a split type hoisting method for a 5MW land type wind generating set. According to the method, a cabin is hoisted in a split mode, and split into a cabin body, a generator, a maintenance crane and a top housing according to the weight and the boundary dimension of all parts of the cabin and the hoisting capacity of a main hoisting machine; after the cabin is split, software is utilized for analyzing and recalculating the gravity center position to adjust the design of a hoisting sling, and therefore the level and the safety of cabin hoisting are ensured. The main hoisting machine is utilized for sequentially installing the cabin body and the generator in place and sequentially installing the maintenance crane and the top housing in place. According to a general scheme, a 1600t crawler crane is needed when a whole hoisting scheme is adopted for a 5MW fan, while by means of the implementation of the method, the construction requirement can be met by adopting a 1000t crawler crane, and therefore the construction cost is effectively saved.

The invention relates to the technical field of building construction, in particular to a building pile foundation construction method. Comprising the following steps that S1, surveying and setting out are conducted, a foundation is leveled, and the position of a pile foundation is marked; s2, a mud pit is dug between the pile holes, and drainage grooves are dug around the pile holes; s3, lowering and mounting the pile casing; s4, slurry is poured into the pile hole; s5, the positions of coordinate points and the drilling sequence are determined, and a drilling operation rack used for supporting a drilling machine is laid on the construction plane of the building pile foundation; s6, drilling is conducted; s7, hole cleaning; s8, lowering a reinforcement cage; s9, after hoisting of the reinforcement cage is finished, concrete pouring is conducted; and S10, after initial setting of the concrete, the pile casing is pulled out of the pile hole, and a pile foundation is formed. The construction method is convenient to operate, high in construction speed, capable of saving materials and obvious in economic benefit, and construction efficiency is improved while pile foundation construction quality is guaranteed. The method is mainly applied to the aspect of building pile foundation construction.
