AI Technical Summary
Water accumulation in cable trenches can easily clog water pumps, affecting the stability of water suction. Existing technologies are insufficient to effectively prevent cable immersion.
A precast concrete trough is installed in the cable trench, with a grid plate and support net inside the bottom box. Combined with the filter and water pump suction, a water collection area is formed. The support net and filter intercept dirt and debris, ensuring the stable operation of the water pump.
It achieves stable water suction, prevents cables from being soaked, improves the moisture resistance of cable trenches, reduces the risk of water pump blockage, and lowers the risk of cable failure and maintenance costs.
