1. Drainage capacity is the minimum requirement of the floor drain, because it is originally a device used to remove ground waste water. The necessity of floor drain installation is also reflected in the emergency leakage port when it is used as a burst water pipe or faucet to avoid bursting water pipes or faucets. The expansion of flood losses after closure failure.
Common sense of installation and use: the floor drain grates should be slightly lower than the ground. The floor must be sloping and sloped towards the floor drain. When the broom is used to sweep the floor drain with difficulty, it is too late to regret it. The floor drain should not be installed in places where water does not often accumulate. The design of the floor drain should avoid the location where kitchen and bathroom equipment may be installed. It is forbidden to move the floor drain in a rough house that has only been installed with a water-sealed anti-odor floor drain during decoration. Because this is like there are only two moving methods:
One is to lay pipelines on the rough floor. Calculated according to the current 50 type with the smallest drainage pipe diameter. Leveling the ground requires laying an extra layer of concrete with a thickness of 7 cm. If you also want to ensure that the floor drain water seal is qualified, that is, more than 5 cm. The height of the cladding floor and the pipe slope will be a 15 cm thick concrete cushion for this random modification. It is conservatively estimated that the cost will be more than 300 yuan. It is only for the modification and installation of the floor drain that may not meet the requirements of use, and waste Resources and increase the weight of the building should be undesirable. The reason for moving the location of the floor drain is often caused by the installation of kitchen and bathroom equipment. It is recommended to design and install the kitchen and bathroom equipment to avoid the original floor drain or choose to install it in the same-layer drainage system that can change the drainage pipe in a caisson type.
The second is to cut out the slab and move it downstairs, but it must be waterproofed again. The problem is that when the downstairs is not your property right or the ceiling has been renovated, it is often difficult to implement. This is also a factor that prevents the current traps with inspection openings from playing a role when they are blocked.
