A quickly replaceable assembled permeable reactive wall structure and its usage method

Abstract

The present invention discloses a quickly replaceable assembled permeable reactive wall structure and its usage method. The structure mainly includes a diversion wall body, a fixed wall body, multiple assembled permeable reactive walls, a quick replacement device, a hydraulic propulsion device, and a slide rail. The diversion wall body and the fixed wall body are integrally cast. The assembled permeable reactive wall is cuboid-shaped and is docked with the slide rail through a bottom groove. A tractor drives a rotating wheel to move on a transverse support truss, and a winch rotates to drive a sling to realize the lifting / descending of a hook. The slide rail is fixed at the top of the fixed wall body and in the middle of the two side wall bodies, and the hydraulic propulsion device pushes the assembled permeable reactive wall to closely contact, so as to ensure that the pollution plume penetrates the wall body without generating bypass flow. The present invention can realize the quick replacement of the adsorption medium without re-excavation. The replacement process flow is efficient and convenient. Moreover, the granular adsorption medium adopted by the present invention is not easy to cause pore blockage and passivation, and different adsorption media can be selected according to the purification requirements, having a wide engineering application prospect.
