The invention relates to the field of building construction, in particular to a basement deep foundation pit anti-blocking drainage structure and a using method thereof. The basement deep foundation pit anti-blocking drainage structure comprises a first drainage pipe, the first drainage pipe comprises a first inner pipe and a first outer pipe, a second gas pipe is arranged in the first inner pipe, and a first water inlet block is arranged below the first drainage pipe; a first gas inlet pipe is arranged on the first water inlet block, a first exhaust pipe is arranged outside the first gas inlet pipe, a first water suction pipe is arranged outside the first exhaust pipe, a first gas groove communicating with the first gas inlet pipe is formed in a first bottom plate, first exhaust holes distributed circumferentially are formed above the first gas groove, high-pressure gas is introduced into the upper end of the second gas pipe and the lower end is connected with the first gas inlet pipe, the upper end of the first inner pipe is connected with an exhaust fan, the lower end of the first inner pipe is connected with the first exhaust pipe, the upper end of the first outer pipe is connected with a water suction pump, and the lower end of the first outer pipe is connected with the first water suction pipe. Accumulated water on the outer side of a first filtering ring moves through air bubbles to reduce sludge and waste residues on the outer side of the first filtering ring, and blockage is avoided.
Description
technical field [0001] The disclosure belongs to the field of building construction, and in particular relates to an anti-blocking and drainage structure for a deep foundation pit in a basement and a use method thereof. Background technique [0002] In order to ensure the safety and stability of the underground space formed by the excavation of the ground during the construction of the underground structure, the retaining structure, groundwater control, environmental protection and other measures are called foundation pit engineering. Foundation pit engineering is a system engineering integrating geological engineering, geotechnical engineering, structural engineering and geotechnical testing technology. Its main content: engineering survey, support structure design and construction, earthwork excavation and backfill, groundwater control, information construction and surrounding environmental protection, etc. The simplest and most economical way to construct a foundation pi...
