Comparison Table of Standard Drainage Ditches and Special Linear Drainage Ditches
| Point-type grating | Cast-in-place drainage ditch | Resin finished drainage ditch | |
| Load-bearing capacity | Poor dynamic load capacity | Poor dynamic load capacity | Professional calculation and design, with static and dynamic load capacities meeting standard requirements. |
| Water collection capacity | The water collection capacity is limited and depends on the design size of the grating. | Good | A unique cover plate design for water collection and containment achieves high water-collection efficiency over a specified area. |
| Drainage capacity | Subsurface drainage pipes are prone to clogging, leading to poor drainage and a high risk of surface water accumulation. | The interior of concrete drainage channels is rough, making them prone to debris accumulation and resulting in poor drainage. | The inner wall of the trench is smooth, enabling linear water conveyance and higher drainage efficiency. |
| Construction slope finding | The grating openings are prone to clogging, leading to poor drainage; under high-flow conditions, the drainage rate is slow, and water tends to accumulate on the surface. | Excavating a slope is more difficult under conditions of limited floor-to-floor height. | Three types of slope are available. |
| On-site installation | Easy | On-site masonry is required, which is time-consuming and involves numerous procedures. | Finished products are delivered to the construction site, enabling rapid installation. Standardized construction procedures and on-site guidance are provided. |
| Product quality | The materials are typically composite materials and cast iron, which are prone to damage or loss. | The trench body, edge protection, and cover plates are supplied by different manufacturers, with no unified standards. | The entire system is supplied by a single manufacturer, with product quality compliant with the European EN 1433 standard and certified as compliant by a domestic testing institution. |
| Safety of Use | General | Displacement, collapse, and missing sections can all lead to pavement safety issues. | A dedicated locking system is provided for the cover plates and trench bodies. |
| Appearance | General | Poor neatness and tidiness | Aesthetic and concise; industrialized products are relatively uniform. |
| Trash cleanup | Difficult; long cleaning time. | Incomplete cleaning results in debris adhering to the concrete channel surface. | Features self-cleaning functionality and comes with professional waste-collection accessories. |
| Daily Maintenance | Complex | Complex | Requires minimal maintenance, reducing upkeep costs. |
| Chemical corrosion resistance | None | None | Excellent; accompanied by a chemical corrosion resistance test report. |
