Problems solved by technology

Prefabrication and shipment of large-scale components using the above methods encountered the following problems: 1) The lifting capacity of the floating crane is limited, which is not suitable for the shipment of large-scale components; 2) The delivery method of airbags and slide trolleys, although the delivery capacity can reach 2000 Tons, but it is still difficult to meet the requirements for larger components (for example, more than 10,000 tons), and the two shipping methods are cumbersome, have high requirements for foundations, jacking, mobile traction and other equipment, and on-site command and operation also have great challenges. Difficulty; 3) The dry dock method overcomes the limitation of shipping weight, but the prefabrication and lifting of components are all in one dock area, prefabrication and shipping cannot be carried out at the same time, and flow operations cannot be formed, which increases the pressure on the construction period. At the same time, The dry dock method requires that the components be prefabricated directly in the dock area, and the dry construction conditions are put forward for the dock area. However, the elevation of the site in the dock is below sea level, and the hidden dangers of seepage prevention, flood control and waterlogging in the dock are relatively large, which is not conducive to creating dry construction. condition

Abstract

The invention relates to a working method for manufacturing large prefabricated components on a large scale in an assembly line manner and outfitting, lifting and shipping the large prefabricated components by the aid of a deep and shallow dock combination which comprises a shallow dock zone and a deep dock zone. The deep and shallow dock combination comprises a fence for stopping seawater from flowing into the deep and shallow dock combination. The shallow dock zone for primarily outfitting and lifting the large prefabricated components and the deep dock zone for secondarily outfitting and lifting the large prefabricated components are arranged in the fence; a shallow dock gate for opening and closing the shallow dock zone is arranged at one end of the fence, and a deep dock gate for opening and closing the deep dock zone is arranged at the other end of the fence. The working method has the advantages that large prefabricated component manufacturing, outfitting, lifting and shipping procedures can be carried out in an assembly line manner owing to the design of the shallow dock zone and the deep dock zone, accordingly, the construction time can be saved, and the construction progress can be accelerated.

Description

technical field [0001] The invention relates to an operation method for realizing large-scale batch assembly line production, outfitting, floating, and shipping of large prefabricated components through a combination of deep and shallow docks composed of a shallow dock area and a deep dock area. Background technique [0002] Large-scale prefabricated components are an important part of offshore and coastal projects. Rapid prefabrication and safe transportation of large prefabricated components are important links to ensure project quality and construction progress. [0003] At present, large prefabricated components mainly include large caissons and tunnel immersed tubes. The prefabrication and shipping methods of large prefabricated components mainly include: 1) Generally, caissons are prefabricated on dry land because of their small weight, stored, hoisted by floating cranes, and transported by semi-submerged barges; 2) Large caissons exceed the lifting capacity of floatin...
