挖沙船在長(zhǎng)江或湖泊深層挖沙作業(yè)的注意事項(xiàng)

Precautions for digging sand in deep excavation of Yangtze River or lake

Our daily life in the mining of sand and gravel, the current open-pit placer has been mined almost, and now China's natural ecological environment protection more and more stringent, making the gravel resources increasingly scarce. It is not only to create wealth, but also to alleviate the shortage of sand in the current construction by using dredging sand to carry out a reasonable operation on the rivers and lakes. Moreover, the reasonable sand mining also plays a dredging role to the rivers and lakes, which is beneficial to the sustainable development of rivers and lakes.

Sand dredger in the use process always because of other factors and lead to the smooth production, so in peacetime we should pay more attention to its scientific management. For dredging, the main investigation is the work efficiency and working quality and dredging operation flow. As long as it is involved in dredging machinery, quality and efficiency are the most critical, dredging machinery is required to be certain of the season, we pay more attention to the performance of all aspects of sand pumping, first check the engine circulating water level, check the hydraulic oil tank and open the hydraulic oil tank oil outlet total valve, check engine, gear box, sand pump, bearing box, oil level. Then open the outer circulation water system of the subsea valve, all the valves are adjusted to the working state. Finally to the operating room to see the operating cabinet of the total power switch is disconnected, the button all reset to ensure that everything is normal. Sand dredger failure to dig the sand cabin below, close the power, start the knife, turn on the engine monitor, followed by the sludge catchment to carry out the whole process of monitoring, regular to the interception ditch clean-up and high, so as to avoid the backflow caused by the soil or water pollution. It is also needed to carry out rigorous inspections of the pipeline outside the field to prevent problems caused by the damage to the slurry.
