AI Technical Summary

Technical Problem

When constructing underwater anchor cables in water-rich sand layers, existing technologies struggle to balance the power supply for drilling operations, leading to water and sand inrush problems and low construction efficiency.

Method used

The construction system is equipped with multiple drilling rigs. The control module generates control signals to regulate the output power of the power unit, ensuring that the drilling rig completes different types of power consumption needs within the optimal working range. Different drilling rigs are used alternately for drilling and grouting operations to form water-stopping and sealing bodies.

Benefits of technology

This effectively avoids water and sand inrush problems, improves drilling quality and construction efficiency, and ensures high efficiency and balance in power utilization.

Abstract

This invention relates to an underwater anchor cable construction system and method for water-rich sand layers. The construction system includes: a construction module for performing underwater anchor cable construction operations according to a construction plan; and a control module for generating control signals during the construction operation to adjust corresponding parameters in the construction plan. The construction module is equipped with at least one drilling rig connected to a power unit for at least performing drilling operations. The power unit can be controlled by the control signals generated by the control module to adjust the proportion of its output power to the drilling rig. The output power allocated by the power unit according to this proportion, in a manner that maintains an optimal working range, can be supplied to the corresponding type of power consumption of the drilling rig. The construction method includes: formulating and improving a construction plan based on field exploration data, experimental data, and / or simulation results; and performing construction operations according to the formulated construction plan to at least drive the power unit to output corresponding power.
