A blocking closure and a method for blocking and sealing a polluted area

Abstract

The invention provides a barrier closure and a method for barrier closure of a polluted area. The barrier closure comprises: an anti-seepage plate, the anti-seepage plate includes a first plate and a second plate, and the first plate is horizontally The two ends in the direction are provided with a first connection structure, and the two ends of the second plate in the horizontal direction are provided with a second connection structure; the sleeve plate, the sleeve plate is hollow, and is sleeved on the anti-seepage plate The outer side is used to drive the anti-seepage plate downwards to insert into the isolation closed area, and the cover plate includes a first cover plate and a second cover plate respectively sleeved on the outer sides of the first plate material and the second plate material. According to the present invention, the construction cost is low, the barrier and sealing effect is good, the operation is convenient and simple, and the corrosion resistance is strong and the service life is long, which can well achieve the effect of blocking the outward diffusion of pollutants and the risk control of polluted sites, and effectively creates The conditions and risk management and control environment for emergency restoration of contaminated sites in the later period are clarified.

Description

technical field [0001] The invention relates to the field of garbage disposal, in particular to a barrier closure and a method for barrier closure of a polluted area. Background technique [0002] At present, the pollution of soil and groundwater is relatively common and serious. On the one hand, the environmental protection awareness of the national chemical industry park is not strong in the early stage, and the laws related to soil environmental mirror protection are not complete. Therefore, the chemical industry park has secretly buried and discharged pollution into the ground. On the other hand, in order to cope with the siege of waste in the early days, some simple landfills that did not meet the current national norms and standards were built. Because of the low landfill access standards and insufficient strict and standardized management, a large amount of chemical waste Mixed domestic waste enters the landfill for landfill. The high-concentration and complex-composi...
