Underground blind ditch and permanent water-collecting well comprehensive dewatering system applied to basement

Abstract

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.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to an integrated dewatering system for an underground blind ditch and a permanent water collection well applied to a basement. Background technique [0002] In the usual basement engineering construction, after the basement is backfilled or the main body construction meets the anti-floating requirements at a certain height, the precipitation will stop. During the construction or use of some projects after the precipitation stops, when the rainy season comes, the groundwater level rises rapidly, and sometimes it will greatly exceed the groundwater level measured by the geological survey. The basement waterproofing method according to the conventional design may not meet the requirements under the abnormal groundwater level Waterproof requirements, resulting in leakage. [0003] Therefore, designing a basement dewatering system to meet the waterproof requirements unde...
