[0002] At present, concrete pouring structures are widely used in sewage treatment plants, accident ponds, rain and sewage storage ponds. However, there are more and more corrosive media in domestic sewage, industrial wastewater, initial rainwater, etc. The exposed concrete pouring structures can no longer meet the requirements of corrosion resistance and impermeability. The prior art improves the corrosion resistance and impermeability of concrete pouring structures by lining high-density polyethylene boards inside the concrete pouring structures. Before pouring concrete into the cavity between the inner formwork and the outer formwork, the high-density polyethylene board is first measured and cut, and then the high-density polyethylene board is fixed on the inner formwork by a large number of nails. After the concrete is poured, the high-density polyethylene board is lined on the inner side of the pool body. After removing the inner formwork and the outer formwork, the nails fixing the high-density polyethylene board need to be pulled out, leaving a large number of nail holes on the surface of the high-density polyethylene board. Subsequently, the nail holes need to be filled by melting polyethylene. This method of lining the high-density polyethylene board has errors in measuring the high-density polyethylene board, and the use of a large number of nails for fixing and filling the nail holes greatly reduces the efficiency of building a concrete pool with a high-density polyethylene board lined inside.
