Underground blind ditch and permanent water-collecting well comprehensive dewatering system applied to basement
The invention belongs to the field of building construction, and particularly relates to an underground blind ditch and permanent water-collecting well comprehensive dewatering system applied to a basement. The underground blind ditch and permanent water-collecting well comprehensive dewatering system applied to the basement comprises a water-collecting well on a base soil layer, the part, outside the base soil layer, of the water-collecting well and adjacent foundation pit slopes are filled with backfill, a submersible pump with a water level control valve is arranged at the bottom in the water-collecting well, a sand well cover plate covers the wellhead of the water-collecting well, a drain pipe connected with the submersible pump penetrates through the upper portion of the sand well cover plate, an underground blind ditch is dug in the base soil layer and internally provided with an underground blind ditch drainage pipe, holes with the diameter of 5 are formed in the underground blind ditch drainage pipe at intervals of 50 mm, and the underground blind ditch drainage pipe is communicated with the water-collecting well. Underground water is gathered in the water-collecting well through the underground blind ditch, the water level control valve is arranged in the water-collecting well, and after water level in the water-collecting well reaches a certain height, the submersible pump is started to drain water.
