AI Technical Summary

Technical Problem

Due to the development of karst karst fractures in landfills in karst landforms, groundwater seeps through the fractures, increasing the difficulty of pollution control, and the existing technology is difficult to effectively solve this problem.

Method used

A method for infiltration control of crack water infiltration in landfills was designed, including exploration of landfills, determining the location of karst fractures in the mountain, establishing horizontal diversion tunnels, water collection holes and leachate pumping wells, and collecting groundwater through these structures to avoid infiltration.

Benefits of technology

It effectively controls the infiltration of groundwater through mountain karst fractures, reduces the overflow of pollutants in landfills, increases the proportion of leachate collection, reduces the amount of pollutant released, and saves construction investment and engineering costs.

Abstract

The invention discloses a karst landform area landfill fissure water infiltration management and control method which comprises the following steps: exploring a landfill, and determining the position of a mountain karst fissure; a horizontal flow guide tunnel is built on the periphery, close to the mountain karst fissure side, of the landfill; water collecting holes are formed in the horizontal flow guide tunnel; and a leachate pumping and draining well is built in the landfill close to one side of the horizontal diversion tunnel. According to the karst landform area landfill fissure water infiltration management and control method, underground water on the two sides is effectively controlled to infiltrate into the landfill in a planar mode through the mountain karst fissures, the construction investment is greatly saved, the construction difficulty is low, and the construction period is short.
