A vacuum preloading soft foundation treatment system and treatment method combined with electroosmotic technology

Abstract

The invention relates to the technical field of soft foundation treatment, in particular to a vacuum prepressing soft foundation treatment system in combination with an electroosmosis technology. Thevacuum prepressing soft foundation treatment system comprises a power source, a plurality of drain boards inserted into the soil and a sealing film covering the multiple drain boards. The drain boardsare fixedly connected with installation pillars, the installation pillars are internally provided with metal wires in a penetrated manner, the drain boards are connected with connecting pieces, a flow guide pipe is connected between every two adjacent connecting pieces, and the flow guide pipe located at the end is connected to a vacuum pump. According to the technical scheme, the vacuum prepressing soft foundation treatment system is mainly characterized in that the two ends of each connecting piece are provided with bayonet sockets correspondingly, the two bayonet sockets are connected through a conducting medium, the two ends of each flow guide pipe are provided with connecting plugs for being matched with the bayonet sockets, the two connecting plugs are connected through a conductingmedium, and each connecting piece is internally provided with a connecting device for connecting the corresponding metal wire with the corresponding bayonet socket through the conducting medium. By means of the vacuum prepressing soft foundation treatment system, connection between the drain boards and the power source is facilitated, and the effect of shortening the construction period is reached.

Description

technical field [0001] The invention relates to the technical field of soft foundation treatment, in particular to a vacuum preloading soft foundation treatment system and method combined with electroosmosis technology. Background technique [0002] Soft foundation treatment, also called soft foundation treatment, is that if the foundation is not strong enough before construction, in order to prevent accidents such as building instability caused by foundation sinking and cracking after construction, it is necessary to treat the soft foundation to make it strong enough for settlement. The process of improving the consolidation degree and stability of the soft foundation to meet the design requirements, vacuum preloading is a common method for soft soil foundation treatment in coastal areas of my country. [0003] The vacuum preloading method is to lay a sand cushion on the surface of the soft ground that needs to be reinforced, then bury the vertical drainage channel, and then...

Problems solved by technology

[0005] When realizing the circuit connection of the conductive plastic drainage board, the plastic board needs to be peeled off to expose the metal wire, and the metal wire is connected to the wire connected to the power supply before waterproofing and insulating treatment, and this operation needs to be repeated as many as there are drainage boards Second, the construction process is more cumbersome, which leads to the slowdown of the overall construction progress and prolongs the construction period.
