Abstract

The invention discloses an improved vacuum dewatering system. The improved vacuum dewatering system comprises a plurality of first sleeves, a plurality of second sleeves, a plurality of vacuum dewatering pumps, a plurality of gas injection pumps and a filling pump, wherein the first sleeves and the second sleeves are inserted in a foundation; the insertion depth of the first sleeves is 3 m to 7 m; the insertion depth of the second sleeves is 10 m to 15 m; a plurality of through holes are formed in the side walls of the first sleeves and the second sleeves; the vacuum dewatering pumps are connected with water pumping pipes which are selectively connected with the first sleeves or the second sleeves; the gas injection pumps are connected with gas injection pipes which are selectively connected with the first sleeves or the second sleeves; and the filling pump is connected with a filling pipe which is selectively connected with one of the first sleeves or one of the second sleeves. According to the improved vacuum dewatering system, defects of the prior art can be improved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of ground treatment, in particular to an improved vacuum dewatering system and a control method thereof. Background technique [0002] In recent years, the economy and infrastructure of major cities along the river and along the coast have developed vigorously, and further urban development plans have been made. The scale of construction projects such as ports, airports, and roads has been expanding day by day. The silt is used for land reclamation or to construct the land area of ​​the wharf port, which has become an important means of land development. However, the sand or silt dredged on the beach has high water content and poor soil quality. If it is not treated, it is generally difficult to meet the requirements for the foundation of the project construction. Chinese invention patent application CN 101215833A discloses an air-injection vacuum dewatering method, which has an obvious drainage effect. Ho...
