保定检查井钢模具厂

The plastic inspection well is made up of well seat, wellbore, manhole cover and plastic inspection well fittings. Buried well drainage pipes, such as PVC-U double axial hollow pipe and HDPE hollow winding pipe, can be used for inspection well.

根据接管数和角度不同有起始井座、直通井座、三通井座、四通井座、90度弯头井座等。为了适应各种排水状况，塑料检查井同时配套有内外径转换接头、马鞍接头、变径接头、汇合接头、变角接头等与之配套的塑料检查井零配件。这些零配件和井座共同用来保障整个排水系统的流通性和密封性。

According to the number and angle of the nozzle, there are initial well block, through well seat, three well seat, four well seat and 90 degree elbow well seat. In order to adapt to various drainage conditions, the plastic inspection well is equipped with internal and external diameter conversion joint, saddle joint, variable diameter joint, confluence joint, angle joint and so on. These spare parts and well seats are used together to ensure the circulation and sealing of the whole drainage system.

检查井井盖可采用铸铁检查井盖、复合材料检查井盖、钢纤混凝土检查井盖。质量符合现行《建筑小区排水用塑料检查井》CJ/T233-2006的要求。颜色为白色或灰色，井筒内外壁应光滑、平整表面不应有气泡、裂口、凹陷、色泽不均匀及分解变色线。塑料井筒井座在15KN静载载荷压力下无开裂、裂缝。

The cast iron inspection cover, composite inspection manhole cover and steel fiber concrete manhole cover can be used for the inspection well lid. The quality is in line with the requirements of the current "plastic inspection well for building drainage area" CJ/T233-2006. The color is white or gray, and the inside and outside walls of the shaft must be smooth and smooth. There should be no bubbles, cracks, dents, uneven colors and discoloring lines. There are no cracks and cracks in the plastic shaft wellbore under 15KN static load pressure.
