[0002] Sustainable treatment of contaminated sites refers to a comprehensive solution that uses scientific and technological means to repair pollution while taking into account resource recycling, ecological protection and socio-economic benefits.

[0003] At present, there are many shortcomings in the existing contaminated site barrier facilities. First, most of the traditional cement or plastic barrier walls are cast as a whole, which makes their transportation and installation extremely difficult and extremely inconvenient in later maintenance. Second, the interlayer connection of the existing barrier structure mainly relies on adhesives or welding. However, the durability of these connection methods is poor and leakage is prone to occur. Third, the repair module and the main structure of the traditional barrier facility are independent of each other, which leads to its low integration and poor performance in pollution prevention and control efficiency. Therefore, the present invention proposes a barrier fence for sustainable treatment of contaminated sites and a construction method thereof. Summary of the invention

[0011] Through the above technical solution, the mounting blocks connected to the end faces of the support rods are bolted to the connection points of the opposite surfaces of the barrier composite plate and the baffle, and the adjusting bolts are rotated at the same time to drive the connecting blocks to move, thereby making the sliders on the end faces of the connecting rods slide and adjust, and then making the support rods press against the connected and fixed mounting blocks, thereby fixing the barrier composite plate and the baffle as a whole.
