Description
Technical Field
The invention relates to a construction method for mounting an assembled wind driven generator by an offshore topdown construction method.
Background
When the existing offshore wind driven generator is installed, two methods are generally adopted: the first is that: firstly piling the piles on the seabed, then fixedly mounting a foundation platform and a cylinder column on a pile foundation, and mounting fan blades on the foundation platform or the cylinder column, namely the traditional sequential method, the method has multiple steps, long construction period and multiple uncontrollable factors in field construction; secondly, the following steps: the method adopts a caisson type chassis, integrally installs a fan, pulls the fan to a preset sea area, and then pumps air from the chassis to sink into seabed soft soil under negative pressure, and because the weight of the fan reaches 2000-4000 tons and no pile foundation exists, the diameter of the chassis generally needs more than 30 meters and the height of the chassis is more than 10 meters, the consumption of raw materials such as steel and the like is huge, and the cost is high.
Disclosure of Invention
The invention aims to provide a construction method for installing an assembled wind driven generator by an offshore topdown construction method, which is convenient to construct and low in cost.
The technical solution of the invention is as follows:
a construction method for mounting an assembled wind driven generator by an offshore topdown method is characterized by comprising the following steps: comprises the following steps;
(1) the method comprises the following steps that a chassis, an upright post and fan blades of the wind driven generator are assembled on land or a harbor basin, a hole capable of penetrating through a pile is reserved on the chassis, a precast pile is vertically placed on the periphery of the upright post, the pile bottom is inserted into the reserved hole, and a pile body and the upright post are temporarily fixed to prevent falling off; then, the whole device is pulled to a preset sea area by a tugboat, and the whole device is sunk to a preset position of the sea bottom;
(2) the precast pile is hoisted by a crane arranged on a tugboat or a floating dock, the temporary fixation between the precast pile and the upright post is released, and the pile is driven to the seabed by a preset depth through a vibration hammer;
(3) and the pile top and the chassis are permanently and fixedly connected through a fixed structural part.
The fixed structural part is one or more of a bolt, a mortise and tenon joint and a bolt and screw structural part.
And (3) pouring underwater rapid-hardening concrete around the fixed structural member after the fixed connection.
The fan device is prefabricated and assembled in a factory, the quality is controllable, only sinking and piling are needed in a preset sea area, the reverse construction method is convenient to construct, an offshore construction platform does not need to be additionally erected, a caisson can be reduced or eliminated, and the cost is greatly saved.
The present invention will be further described with reference to the following examples.
Detailed Description
