How to construct the drainage net?

Release time:

2024-10-17

The construction of the drainage network needs to follow certain steps and precautions to ensure construction quality and safety. During the construction process, operations should be carried out strictly in accordance with the design requirements and construction specifications, quality inspection and acceptance work should be strengthened, and problems should be discovered and handled in a timely manner.

Ⅰ. Construction preparation

1.Design review: Before construction, the design of the drainage net should be reviewed to ensure that it meets the engineering needs and specifications. At the same time, the design intent and key points should be understood to provide accurate guidance for construction.

2.Site cleaning: Remove debris, water accumulation, etc. in the construction area to ensure that the working surface is flat and dry. For areas where drainage nets need to be laid, special attention should be paid to the flatness and cleanliness of the ground.

3.Material preparation: According to the design requirements and engineering volume, purchase an appropriate amount of drainage net materials, and check their quality certification documents and appearance quality. Commonly used drainage net materials include plastic drainage boards, geotextiles, etc.

Ⅱ. Base treatment

1.Clean the base: Treat the base, remove impurities such as floating dust and oil on the surface, repair and level it, and ensure that the base is solid, dry and clean.

2.Determine the baseline: According to the design requirements and the size of the construction area, determine the baseline position to ensure the accuracy and flatness of the drainage net laying.

Ⅲ. Drainage net laying

1.Laying the drainage net: Lay the drainage net on the baseline position to ensure flatness and wrinkles. For projects with overlapping requirements, overlapping treatment should be carried out in accordance with design requirements. During the laying process, attention should be paid to the direction of the drainage net being consistent with the direction of water flow.

2.Fixing the drainage net: Use appropriate fixing methods to fix the drainage net on the base to prevent it from shifting or sliding. Common fixing methods include nailing, pressure strips, etc. During the fixing process, it should be ensured that the fixing points are evenly distributed and firmly fixed.

IV. Connection and closing treatment

1.Connection treatment: For parts that need to be connected, special connectors or adhesives should be used for connection treatment to ensure that the connection is firm and the sealing is good. During the connection process, care should be taken to avoid damaging the drainage net material.

2.Closing treatment: Carefully handle the closing to ensure the appearance quality and waterproof performance. The closing should be flat, wrinkle-free, and well sealed.

V. Quality inspection and acceptance

1.Quality inspection: After the construction is completed, the laying quality of the drainage net should be inspected to ensure that it meets the design requirements and relevant standards. The inspection content includes the flatness, fixing firmness, connection sealing, etc. of the drainage net.

2.Acceptance work: For qualified parts, acceptance should be carried out in a timely manner. During the acceptance process, relevant data should be recorded and a completion acceptance report should be prepared. For unqualified parts, rectification should be carried out in time until the acceptance standards are met.

VI. Precautions

1.Construction environment: During the construction process, the base layer should be kept dry and clean, and construction should be avoided in rainy or windy weather. At the same time, care should be taken to prevent the base layer from mechanical damage or man-made damage.

2.Material protection: During transportation and construction, care should be taken to protect the drainage network materials to prevent them from being damaged or contaminated. At the same time, storage and preservation should be carried out in accordance with the requirements of the specifications.

3.Safety measures: During the construction process, safety operating procedures should be strictly followed to ensure the personal safety of construction personnel. At the same time, necessary warning signs and temporary enclosures should be set up to prevent non-construction personnel from entering the construction area.
