Problems solved by technology

When the traditional rock drilling process is deep (especially when the water depth exceeds 15 meters), the rock drilling effect is not obvious, and the energy consumed by the water is relatively large, resulting in an increase in rock drilling costs
The reef blasting process has caused great damage to the environment, especially in marine life protection areas, where the reef blasting process has seriously damaged the marine ecology; when there are oil terminals or dangerous areas around the construction, the reef blasting process also has huge hidden dangers
[0004] For the sake of environmental protection and reef removal construction in the waters adjacent to the operating wharf facilities, the traditional reef blasting technology has huge safety hazards, and underwater blasting construction technology is not allowed, which also proposes new methods for underwater rock removal.

Abstract

The invention discloses a combined rock excavation construction method using a backhoe dredger and a drill ship. The combined rock excavation construction method is characterized by comprising the following steps of making early-stage preparations for construction, making a scheme, cleaning away a sludge covering layer, conducting drilling treatment, excavating rock through the backhoe dredger, conducting shallow spot dredging and conducting inspection and acceptance when a project is completed. According to the combined rock excavation construction method, the requirement for fairway construction is met, the influence on the ecological environment is also reduced, construction efficiency is improved, potential safety hazards are reduced, the national sustainable development strategy is satisfied, and the popularization range is broad.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a combined rock digging construction method of a backhoe dredger and a drilling rig ship. Background technique [0002] With the expansion of the scope of international economic exchanges, the development of the shipping industry is also accelerating. The scale of domestic ports and waterways is getting larger and larger. Large-tonnage shipping ships need to deepen the waters entering the port. A large number of weathered rocks are excavated in dredging projects. The excavation of hard weathered rock puts forward higher and higher requirements for mechanical capacity and excavation efficiency. [0003] When the rock compressive strength is greater than 40MPa, it is difficult for traditional large-scale construction ships to carry out reef removal construction. When excavating slightly weathered hard rock with greater compressive strength, rock drilling or reef blasting is gene...
