Device and method for reinforcing foundation through vacuum preloading-electroosmosis-heating combined biological enzymes

Abstract

The invention discloses a device and method for reinforcing a foundation through vacuum preloading-electroosmosis-heating combined biological enzymes. An electric heating film, a hollow round pipe, anouter wrapping core plate and a filter film are arranged in a conductive heating plastic drainage plate, a plurality of metal wires are arranged in the hollow round pipe, drainage holes are formed inthe hollow round pipe at equal intervals in the length direction, the metal wires are connected into a wire network according to the cathode and the anode of the drainage plate correspondingly, the wire network is located in a sealing coating and penetrates through a sealing ditch to be connected with a waterproof plug, the waterproof plug is connected with a direct-current power supply through awire, and the direct-current power supply is connected with an air energy generator through a wire; the conductive heating plastic drainage plate is arranged in soil of a soil body to be reinforced,a plurality of soil moisture measuring instruments and temperature sensors are arranged around the conductive heating plastic drainage plate, the hollow round pipe is connected with a horizontal filter pipe, and the horizontal filter pipe is connected with a vacuumizing device; and a pressurized dissolved solution pumping pipe is arranged in the center of four plastic drainage plates.

Description

technical field [0001] The invention belongs to the technical field of foundation reinforcement treatment, and in particular relates to a vacuum preloading-electroosmosis-heating combined biological enzyme reinforcement foundation device and method, which is suitable for the field of soft soil engineering foundation treatment, especially for those requiring low water content after foundation reinforcement projects are particularly applicable. Background technique [0002] my country's soft soil areas are widely distributed, and most of them are distributed in economically developed areas. With the development of cities and economic growth, the demand for the bearing capacity of soft soil layers is also increasing. In order to meet the construction needs, almost all engineering construction in soft soil areas requires foundation pretreatment. From engineering practice in recent years, it can be found that a single foundation treatment technology has developed into a combinati...
