Description

TECHNICAL FIELD

[0003] Another significant problem: with the proposal of the "double carbon" goal, more and more new energy projects (photovoltaic, wind power, photothermal power generation, energy storage, etc.) are landing in arid regions such as Xinjiang and Gansu. The cable trench with a length of several hundred meters as an important structure in the factory often faces the problem of water accumulation caused by surface rainwater or groundwater entering the cable trench. The conventional method is to set a water collecting pit every certain distance at the bottom of the cable trench, and a rainwater pipe is buried in the water collecting pit and is discharged into the rainwater pipe network in the factory. However, for arid and rainy areas, in accordance with the principle of adapting to local conditions and saving investment, the underground rainwater pipe network is not often set in the factory, and the rainwater in the water collecting pit is difficult to discharge. If a rainwater pump is set to pump water, the energy consumption is large, and the bottom of the trench needs to meet the minimum 0.5% drainage slope, so the buried depth of the cable trench will gradually increase, which has an adverse effect on construction and cost.
