The Netherlands developed a new plastic inspection well

The Dutch company Wayun Plastics recently developed a new type of plastic inspection well for use on municipal roads and sewage pipelines where inspection and cleaning are required. Traditional concrete or steel pipe inspection wells have the disadvantages of heavy weight, high installation cost, large soil application surface, high maintenance costs, and serious phenomena such as leakage and erosion, which pollute groundwater. Plastic inspection wells are made of plastic as raw materials, light in weight, and prefabricated, resulting in simple on-site construction, low installation costs, good water tightness, corrosion resistance, and low maintenance costs. The expansion adjuster designed by Wayun Company based on years of experience is used between the sleeve and the manhole cover. The adjustable range is up to 250 mm, which provides convenience for construction on the road. The plastic inspection well base connection can be flexibly rotated 150, which also has very important significance for the municipal engineering construction. At present, the product is used more and more widely in Europe, and the plastic inspection well is also one of the fastest-growing varieties of plastic products in the region. However, the use and production of this product in China is still blank. According to experts from the Plastics Association, plastic inspection wells will have good prospects for development in China.
