How to design drainage ditches and install fiberglass grilles for car wash shop decoration? There are also several styles of drainage ditch design, mainly determined by the size of the car wash site and surrounding conditions, which generally require professional personnel to design. Below are several styles of drainage ditch.

There are generally three ways to design drainage ditches:
1. Directly use cement pads around the existing ground to create elevated spaces, with some bricks used as support in the middle, evenly distributed. This type is more suitable for large-scale car wash shops.
2. Dig drainage ditches under the parking space according to its size, and then connect all drainage ditches to discharge into the outdoor sewer. This method is currently adopted by most car wash shops.
3. Digging a drain only at the wheel position is a relatively simple and cost-effective method.

The depth of the drainage ditch can be excavated as needed, and the depth should not be less than 15cm; According to the principle of high inside and low outside, the water should be naturally discharged to the sewer pipeline. If it is an indoor pipeline, a sludge sedimentation tank of about 1 cubic meter needs to be set up and cleaned regularly to prevent pipeline blockage in the future; If the drainage volume is large, a pumping pump can be used.
In addition, the trench of the car wash room needs to be kept at a certain distance from the wall, and it is best to lay the trench in the middle of the room. Even if it is close to the wall, it is necessary to leave 2-3 positions for the convenience of workers to work. Ditches can be dug downwards or raised upwards from the ground to create space for underground work. Generally, flat houses can dig drainage ditches downwards, while if there are other spaces or facilities underground, they can only be raised upwards.
The size of the drainage ditch depends on the size of the parking space. Generally, the size of a standard car wash parking space is 6m * 3m. Drainage ditches need to be equipped with some support points, which should be spaced according to the load-bearing capacity of the fiberglass grating. Generally, concrete is used as the material for these support points. The size of the location for placing the car wash grille should be left above the drainage ditch and on the ground. The thickness of the commonly used car wash grille is 38mm, so a height of 38mm should be left. A few centimeters should be left between the grille panel and the ground for easy movement and installation.
