Description

Technical Field

[0001] This utility model relates to the field of flushing equipment management and control systems, and in particular to a DCM engineering vessel pipeline flushing monitoring system. Background Technology

[0002] The Deep Cement Mixing Vessel (DCM) is a specialized construction vessel used for the improvement and reinforcement of soft soil foundations in marine and coastal engineering projects. This vessel integrates several advanced technologies, including underground soil cutting and mixing, precise injection of cement grout, interchangeable high and low grout nozzles, and intelligent control construction. It is an indispensable technical equipment for major marine engineering projects such as land reclamation, harbor construction, cross-sea bridges, and offshore airports. The working principle of the DCM vessel is to add cement or cement-curing materials to soft, cohesive soil in a specific ratio and force-mix it. Through chemical curing, a strong and stable soil structure is formed in the foundation, thereby reinforcing underwater soft soil as the foundation for hydraulic structures. This method can reduce environmental impact, such as reducing the risk of pollutant leakage in land reclamation projects and the impact on marine life.

[0003] During the use of DCM engineering vessels, it is necessary to flush the mud pipelines of the DCM engineering vessels. If the pipelines are not flushed in time, cement slurry will accumulate in buffer tanks, pipelines, valves, etc., forming clumps, blocking the pipelines, and even causing the pipelines to burst due to excessive pressure. This reduces equipment efficiency, increases the maintenance burden on personnel, wastes mud, and increases construction costs. However, the current technology lacks equipment that can effectively monitor the mud pipeline cleaning operations of DCM engineering vessels. Utility Model Content

[0060] Example 2

[0061] This embodiment provides a method for using a DCM engineering vessel pipeline flushing monitoring system, and the DCM engineering vessel pipeline flushing monitoring system involved in this embodiment is the DCM engineering vessel pipeline flushing monitoring system involved in Embodiment 1. The pipeline flushing involved in this embodiment refers to flushing the buffer tank 340 and the pipelines connected to the output end of the buffer tank 340.

[0062] During pipeline flushing, the control console 100 controls the various components in the flushing equipment 300 through either of the two PLC control cabinets 200.

[0063] The controlled content includes:

[0064] Seawater pump 310 continues pumping water, seawater valve 320 is opened, and the conduction path of the three-way valve is controlled, allowing mud pump 330 to pump seawater to buffer tank 340; drain valve 380 remains open, allowing the seawater pumped by mud pump 330 to be discharged through the pipeline to be flushed.
