Description

Technical Field

[0001] The invention relates to the technical field of submerged dam construction, in particular to a precise construction process for twisted W-shaped block groups under great water depth. Background Art

[0002] Twisted King block groups are often used in submerged dam construction in waterway regulation, which can effectively enhance the stability and anti-scouring ability of the dam body. However, under deep water conditions, the traditional Twisted King block group hanging process faces many challenges, as follows:

[0003] Flow rate influence

[0004] In deep water environment, the water flow velocity has a significant impact on the position accuracy of the twist block group during the hoisting process. The flow velocity changes in deep water are more unpredictable, which can easily cause the twist block group to deviate from the predetermined position, thereby affecting the overall layout of the dam body;

[0005] Buoyancy effect

[0006] The influence of buoyancy in deep water environment is more complicated, which not only produces significant buoyancy interference on the lifting equipment, but also affects the sinking posture and stability of the twisting block group. Traditional lifting equipment is difficult to cope with such variable buoyancy, making it difficult to control the construction accuracy;

[0007] Line of sight restrictions

[0008] As the water depth increases and the turbidity of the water body rises, traditional vision-based positioning methods are limited and it is difficult to achieve high-precision positioning and monitoring in deep water. This situation makes it particularly difficult to accurately place the Twisted King Block Group in a deep water environment;

[0009] Lack of precise equipment

[0010] Existing technologies generally lack equipment and methods that can achieve real-time high-precision monitoring and intelligent position adjustment in deep water environments. The limitations of traditional equipment and methods result in low construction accuracy and long adjustment time, increasing construction costs and safety risks.

[0011] Based on the above technical pain points, the present invention proposes a precise placing construction process for twisting king-shaped block groups in deep water. By comprehensively utilizing high-precision positioning systems, underwater real-time monitoring and intelligent adjustment methods, it aims to significantly improve the placing accuracy and construction efficiency of twisting king-shaped block groups in deep water environments, thereby effectively reducing position deviations and quality problems during the construction process. Summary of the invention

[0012] The purpose of the present invention is to provide a precise construction process for placing twisted king-shaped block groups in deep water, so as to solve the problems of insufficient precision and instability caused by factors such as flow velocity, buoyancy and limited vision when placing twisted king-shaped block groups in deep water environment in the prior art.

Based on the twisted king block group lifting and placing device, this embodiment provides an implementation method for accurately lifting the twisted king block group, and the specific process is as follows:

[0087] Preparation before construction: (1) Train construction personnel to ensure equipment operation and safe construction; (2) Determine the installation location and quantity of the twist block group 2 according to the construction design drawing; (3) Install the winch 5, self-retractable rod 6, pulley, hook and steel cable 7, and debug the equipment to ensure the normal operation of each part.

[0088] Pre-construction work: Floating crane 1 goes to the construction area and determines the construction site through GPS positioning; then the crew binds the twist king block group 2 with hooks and steel cables to ensure the stability of the twist king block group 2 during the lifting process.
