scientific research institutes, schools, factories, large square), etc. For heavy enterprises outside the factory, such as port enterprises outside the rain sewage inspection Wells, and use of reinforced concrete brick shaft and bearing cast iron manhole cover, may be more suitable. Particularly low-lying, for the new site as soon as possible in order to come in the rain, storm sewer design requires Φ 1000 and older, and the market can accept Φ above 600 plastic plastic shaft manufacturers almost no storm sewer; The building row of the first 4.5.4 living drainage pipe should not be in the building internal inspection Wells. When must be set, sealing measures should be taken. The author thinks that can be used in a flexible way of doing. Underlying a villa has a toilet, for example, must take the practice of domestic sewage in inspection Wells, well can use plastic instead of brick, and on the plastic manhole covers well set (plastic drainage pipe, buried, along the pillars near outsourcing and roof, the roof rainwater system. Without rain, use this tube for ventilation; When there is rain, the auxiliary rainwater pipe, let indoor sewage well not dry up. Two townhouse, north-south symmetry, the backyard of a 1.6 m between path between court, intermediate to go rain and sewage pipes, in the central axis on both sides of the two sewage inspection Wells, each well to accept north-south six sewage pipe and two east-west sewage pipe. One-way acceptance of three north (or south) sewage branch pipe, and the homes are plastic check well advantage, but this kind of situation, the more likely to use the quality mark rectangular brick well instead of round check well.
