Concrete pouring of the well chamber within the device
Thread Content
Whether it is a valve well or a water seal well within the installation, they are generally prefabricated; only a few are cast in place. However, for convenience, contractors prefer to pour the concrete in two stages, without installing water stop strips. There are no waterproofing measures in place at the location of the construction joint. There are also no specific mandatory provisions in the regulations; where can one find the basis for implementing water-stop measures?
There is such a rule. One must persevere. It is recommended to look for information on water stop strips.
The specifications for petrochemical water supply and drainage pipelines only state that they should be treated as construction joints, without specifying exactly how to do so; other specifications related to water supply and drainage structures don’t provide any guidance either. No explicit provision can be found.
I really haven’t found it. This can be coordinated with the construction party; it should be a method for preventing leaks during construction. If this method is not used, in the event of a leak, the construction party will need to provide an explanation; there are no remedies for such a situation. Explain it in principle. Additionally, it is also necessary to clarify the ownership of the score data provided. For such buildings that are somewhat corrosive, stainless steel or rubber waterstops are required. The key is still to reason and communicate effectively. If communication fails, it’s possible to put the issues in writing in detail; there aren’t really any other options. For reference.
