How is a linear drainage ditch constructed?

A linear drainage ditch is a commonly used drainage facility for collecting and discharging rainwater and wastewater from the ground. The following are the construction steps for a linear drainage ditch.

1. Design: Firstly, a design plan for the linear drainage ditch needs to be created based on specific usage requirements and the geographical environment. The design plan should consider factors such as drainage volume, drainage speed, drainage path, pipe specifications, and construction materials.
2. Site Preparation: Prior to construction, the site needs to be prepared. Start by clearing the construction area and removing debris and obstacles. Then, ensure the ground is leveled for construction.
3. Excavation: Excavate the drainage ditch on the ground according to the design plan. Mechanical equipment such as excavators or loaders can be used as needed. The excavation should match the required depth, width, and length of the drainage ditch. During excavation, it is important to maintain a certain slope for smooth water flow.
4. Frame Reinforcement: After excavating the drainage ditch, the frame reinforcement work needs to be done. Steel mesh is commonly used as the frame material, embedded into the drainage ditch and fixed to the ditch walls. The frame enhances the stability and load-bearing capacity of the drainage ditch.
5. Pipe Installation: Once the frame is fixed, the drainage pipes are laid. Select appropriate pipe specifications and materials based on the design plan’s drainage volume and speed. Plastic drainage pipes are commonly used, with sizes chosen accordingly. When laying the pipes, ensure secure connections and proper sealing.
6. Concrete Pouring: After pipe installation, concrete pouring is required. Select the appropriate concrete mix and pouring technique, pouring the concrete into the drainage ditch to fill the gaps. Pay attention to controlling the cement content of the concrete to achieve the desired strength and durability.
7. Cover Plate Installation: After the concrete has solidified, install the cover plates on the drainage ditch. Generally, lightweight and high-strength materials such as steel plates or plastic are chosen for the cover plates to facilitate regular maintenance and cleaning. Ensure a proper seal between the cover plates and the drainage ditch to prevent foreign objects from entering.
8. Cleaning and Maintenance: After construction is completed, regular cleaning and maintenance of the drainage ditch are necessary. Periodically inspect the operation of the drainage ditch and its ancillary facilities, remove blockages, repair damaged sections, and maintain the drainage ditch’s effectiveness and functionality.
