Abstract

The invention provides a reinforcing device for variable pressure and vacuum pumping of soft soil and an application method thereof. The reinforcing device for variable pressure and vacuum pumping ofthe soft soil comprises a vacuum pumping drainage mechanism arranged in silt, wherein the vacuum pumping drainage mechanism comprises drainage pipes horizontally arranged, first plastic drainage plates vertically arranged and a vacuum pump. The first plastic drainage plates are cavities which are formed by core plates located in the middle part and filter membranes coated on the outer sides of thecore plates, and the upper potion and the lower portion of the cavity are opened. The vacuum pump communicates with the upper ends of a plurality of first plastic drainage plates in a cavity shape through the drainage pipes, and a plurality of vacuum degree monitoring reflector are distributed on the core plates at height. According to the reinforcing device for variable pressure and vacuum pumping of the soft soil and the application method thereof, the problem that the pre-pressing vacuum degree is inadequate, the drainage plates is silted and blocked, and the drainage rate is too low can be solved.

Description

technical field [0001] The invention belongs to the technical field of soft soil treatment, and in particular relates to a pressure-varying vacuum reinforcement device for soft soil and a use method thereof. Background technique [0002] Every year, large-scale river and lake dredging projects and port and waterway construction projects are carried out in our country, which will inevitably produce a large amount of dredged mud. According to incomplete statistics, at least hundreds of millions of cubic meters of dredged mud are produced in my country every year. Just take the following key construction projects as examples: The Yangtze River Estuary Deepwater Channel Improvement Project only has the infrastructure dredging volume of the third phase project reaching 170 million m 3 After the completion of the project, the dredging volume required for annual maintenance is about 30 million m 3 , the Jiangsu section of the east line of the South-to-North Water Diversion Project...
