Chifeng Drainage Board Manager: 133.4529.3123. What quota should be used for the Haengao concave-convex drainage board in landscape engineering? For roof landscape gardens, the concave-convex drainage board should be laid in the green planting area. What quota should be used, and how should it be priced? The waterproof construction process for the Taian Haengao drainage board in underground parking garage floors is as follows: 1. Floor Cleaning: Before construction, the garage floor should be thoroughly cleaned. The construction base must be flat and solid, without phenomena such as sand, sharp protrusions, hollow spots, or pits. 2. The membrane should be laid on the structural floor in a specified overlapping order from front to back and side to side. 3. Small overlapping columns should be fitted into large overlapping columns at both the front and back, as well as the sides. 4. To prevent leakage during construction or sliding of the membrane, glue should be applied to the overlapping edges, or cement should be poured at intervals to fix it with cement points. 3. Pouring: 1. Use C20 fine aggregate concrete to pour over the membrane, leveling it with a straight rod to a height of 1-2cm above the membrane, and allow it to harden before proceeding with subsequent construction. 2. After the concrete has set, reinforce with rebar and pour the concrete surface layer, creating drainage ditches and sumps in the floor. 4. Precautions: 1. The membrane must be completely overlapped and secured to prevent leakage of slurry. 2. Soft-soled or nail-free shoes should be worn during installation to avoid puncturing the membrane. 3. Heavy vehicles should not drive directly on the membrane during installation to prevent crushing or breaking of the material. 4. Fire prevention measures for materials should be noted. 5. Design Specifications: For detailed construction plans and node diagrams, please refer to the national compilation "Underground Engineering Building Structures," "Flat Roof Building Structures II," "Residential Building Structures," and "General Atlas of Building Structures." Application Scope of Drainage Board: Green Engineering: Garage roof greening, rooftop gardens, vertical greening, sloped roof greening, football fields, golf courses. Municipal Engineering: Airports, roadbed, subways, tunnels, landfills. Construction Engineering: Upper or lower layers of building foundations, interior and exterior walls and floors of basements, as well as waterproofing and insulation layers on roofs. Hydraulic Engineering: Reservoir seepage prevention, water storage pools, artificial lakes seepage prevention. Traffic Engineering: Highway, railway bed, embankments, and slope protection layers. Introduction to Haengao Roof Beautification Drainage Board Technology: The Haengao company's roof beautification drainage board is known for its high quality and low price, widely used in various waterproof drainage projects in China. The product is characterized by high hardness and strong flexibility. The construction technical specifications for the roof beautification drainage board are developed according to the "Technical Specifications for Highway Subgrade Construction" (JTG F10-2006), "Quality Inspection and Testing Specifications for Highway Engineering" (JTG F80-2004), and the interpretation manual for "Technical Specifications for Highway Subgrade Construction" (JTG F10-2006). The roof beautification drainage board is suitable for soft soil layers greater than 4 meters thick, typically chosen for treatment with plastic drainage boards. The construction of the roof beautification drainage board must follow regulations, and specific construction questions can be consulted with the Haengao roof beautification drainage board manufacturer. We produce and sell more professionally. The content of the roof beautification drainage board handover includes: construction preparations, reviewing the construction drawings for the garage drainage board, clarifying relevant technical issues, familiarizing oneself with specifications and technical standards, and using approved benchmark points and control lines to determine route edges, center lines, and elevation control points. Construction Methods for Drainage Board: 1. Clean up the construction site of debris, level with cement, ensuring there are no obvious protrusions or depressions. The outdoor garage roof and rooftop gardens should have a slope of 2-5‰. 2. Rooftop greening and outdoor garage roof greening can be used with multi-hole drainage pipes, which will concentrate the water drained from the drainage board to the nearby sewer or urban drainage system. 3. For basement floor seepage prevention, a drainage board should be placed above the foundation before making the floor. The convex side should face down, with blind ditches left around, preventing groundwater from rising; seepage will naturally flow through the drainage board's space into the surrounding blind ditches, and then into the sump. The drainage board is a new type of greening product from our company, applied in urban greening, real estate greening, building foundations, tunnel bridges, highways and railways, rooftop drainage insulation, garage roofs, landscaping projects, and rooftop garden greening, among other areas.
