Embodiment Construction
[0019] Such as figure 1 , figure 2 As shown, a method of using small lifting equipment to install underwater super-heavy components,
[0020] Use small lifting equipment to hoist the component to be installed and the buoy fixed with the component below the water surface; after the buoy is gradually immersed in the water, due to the buoyancy of the buoy, the lifting capacity of the small lifting equipment will gradually decrease. The hoisting equipment gradually increases the working range until it reaches the installation position; after the component is in place, fill the buoy with water, separate the buoy from the component, lift the buoy out of the water, and start the next installation cycle.
[0021] The present invention utilizes the buoy 1 to cooperate with the small hoisting equipment 6 to complete the hoisting, installation and construction of the underwater super-heavy components. It is advisable that the small-sized lifting device 6 is used to hoist the component...

The invention discloses a method for mounting an underwater super-heavy component by utilizing miniature lifting equipment. The method comprises the following steps: by adopting the miniature lifting equipment, at the optimal operating states such as minimum lifting amplitude and maximum lifting arm angle, lifting a to-be-mounted component and a float bowl fixed to the component under the water surface; gradually immersing the float bowl into water, wherein the lifting weight born by the miniature lifting equipment is gradually reduced due to the buoyancy of the float bowl, the operating amplitude of the miniature lifting equipment is gradually increased until a mounting part is reached; and injecting water into the float bowl after the component is placed, separating the float bowl from the component, lifting the float bowl out of the water surface, and starting the next mounting cycle. According to the method for mounting the underwater super-heavy component by utilizing miniature lifting equipment disclosed by the invention, the weight of the lifting component in the operating amplitude range of the lifting equipment is effectively increased, namely the operating amplitude of the lifting equipment is obviously increased when the component of the same weight is lifted.
Description
technical field [0001] The invention discloses a method for installing underwater super-heavy components by using small lifting equipment, which is suitable for hoisting and installation of super-heavy and super-large components in port and navigation engineering. Background technique [0002] In the construction of port and shipping projects, when lifting and installing large-scale components, since the lifting capacity of the lifting equipment is limited by the working range, the lifting capacity will be significantly reduced as the working range increases. Therefore, it is often necessary to use a large lifting ship or a large land crane to cooperate to complete. Large-scale hoisting equipment is used for installation and construction, which has high cost, low efficiency, and difficult positioning on the water. Especially when the project location is relatively remote and it is difficult to dispatch large lifting equipment, this traditional hoisting method cannot meet th...
