Last update date: 2020-05-10 11:50The Secretary for Development Huang Weilun published a blog today (10th) saying that the Drainage Services Department introduced a new type of remote control dredging robot earlier this year. It can remotely operate the robot to carry out dredging to avoid flooding, and in Sham Shui Po and Tsuen Wan The trial was to conduct dredging works for the box-shaped underdrain. He said that compared to traditional methods, robots are safer and faster, and do not need to be restricted to the dry season.

Pan Tianyou, an engineer of the Drainage Services Department, said that rainwater will be discharged into the sea through a box-shaped underdrain, and the sand, mud and dust washed down with the rainwater will accumulate in the canal and become silt, affecting the drainage function of the canal. Dip. To avoid the above, the Department will regularly check the box-shaped culvert and arrange dredging work if necessary.

The staff will first use a crane to lift the robot and send it into the box-shaped underdrain through the wellhead. Afterwards, the operator can observe the condition in the canal through CCTV and sonar detection in the studio, and operate the machine remotely People dredging.

The sludge will be transported to the landfill after being dehydrated
Pan Tianyou said that the robot is about 3 meters long, 1.5 meters wide and 1.5 meters high, and its operation is similar to a vacuum cleaner. After the robot sucks in the sludge, it will pump the sludge to the temporary silt loading and unloading cabinet through the connecting pipe. After dewatering, the sludge will be transported to the landfill.

Safer than traditional methods
He said that according to the traditional method of dredging, workers need to enter the box-shaped culvert to install and control the dredging device, but because the culvert is a closed space, there will be certain safety risks when working inside.
He also said that the traditional method is to cut off the water flow in the culvert and let the staff work without water flow, so most of them are limited to the dry season. On the contrary, the remote control dredging robot can replace the diving process, and can also carry out dredging during the rainy season, speeding up the project progress and reducing costs, and the efficiency of dredging is also significantly improved.
