Description

Technical Field

[0001] The utility model relates to the technical field of rainwater management, and more specifically to a barrier wall for a permeable reaction wall system. Background Art

[0002] The permeable reaction wall refers to a passive in-situ groundwater treatment technology with a filling medium. The permeable reaction wall is set on the cross-section of the contaminated groundwater flow path. Through the contact between the reaction material filled in the wall and the groundwater, the polluted components in the water are degraded and retained, thereby achieving the purpose of repairing the contaminated groundwater. The permeable reaction wall structure includes a barrier wall and a reaction wall.

[0003] After searching, the utility model patent with announcement number CN207392263U discloses a barrier wall for an infiltration reaction wall system, including a waterproof layer, a barrier wall and a wall body, one end of the barrier wall is fixedly connected to a connecting sleeve, one end of the connecting sleeve is sleeved with a reaction system, the other end of the connecting sleeve is fixedly connected to the wall body, a barrier wall unit is fixed inside the wall body, a sealing sleeve is clamped on the outer wall of the barrier wall unit, a vertical expansion joint is provided on the lower surface of the sealing sleeve, a horizontal expansion joint is provided on one side of the vertical expansion joint, and one end of the barrier wall unit is fixedly connected to an outward clamping plate; the patent has a clear and definite structural hierarchy, and the barrier wall volume can be arbitrarily combined according to the actual working conditions through the barrier wall unit, the expansion joint and the clamping plate ensure the stability of the wall body, and the stabilizing layer and waterproof layer inside the wall ensure the durability of the barrier wall, which solves the problem of instability of the barrier wall in the traditional infiltration reaction system and the problem of short life and high maintenance cost of the barrier wall.

[0004] However, the above patent still has the following shortcomings: when the barrier wall blocks the groundwater, the groundwater will flow along the inner wall of the barrier wall to the reaction system. At this time, the groundwater will drive the underground soil to move, which will affect the reaction system's reaction to sewage; in addition, the groundwater blocked by the barrier wall needs to penetrate the soil again to reach the reaction system, which affects the efficiency of groundwater treatment. For this reason, we propose a barrier wall for a permeable reaction wall system. Utility Model Content
