Strengthening the rain protection line: Key points in the construction of glass greenhouse projects

Roof design and construction

Select the appropriate glass material and roof slope: Choose high-quality tempered glass or laminated glass, which has good waterproof performance and strength. Meanwhile, a reasonable roof slope, generally between 20° and 45°, should be designed to ensure that rainwater can slide down quickly and reduce the possibility of water accumulation.

Proper installation and sealing of glass: High-quality sealant should be used to seal the joints between glasses, ensuring that the sealant is uniform, full, free of cracks and bubbles, and preventing rainwater from seeping through the gaps. During the installation process, pay attention to the flatness and verticality of the glass to avoid rainwater accumulation due to improper installation.

Set up gutters and downspouts: Set up gutters along the edge of the greenhouse roof. The width and depth of the gutters should be reasonably designed based on the local rainfall and the area of the greenhouse to ensure that they can accommodate and quickly drain away the rainwater. The number and diameter of downspouts should also be sufficient. Generally, one downspout is set up every 3 to 5 meters, and the diameter of the downspout should not be less than 100 millimeters to ensure that rainwater can be smoothly drained to the ground.

Wall and foundation construction

Wall waterproofing treatment: If the greenhouse walls are built with brick or concrete structures, waterproofing treatment should be carried out on the wall surface, such as applying waterproof coatings or laying waterproof membranes. Waterproof chamfers should be set at the connection between the wall and the floor to prevent rainwater from seeping into the foundation along the wall.

Foundation waterproofing: During foundation construction, it is necessary to ensure the sealing and waterproofing properties of the foundation. Pour a layer of waterproof concrete on the surface of the foundation or lay waterproof rolls, and then proceed with the subsequent construction. The connection between the foundation and the wall should be well sealed to prevent rainwater from seeping through the gaps between the foundation and the wall.

installation of doors and windows

Choose doors and Windows with good waterproof performance: Doors and Windows are the weak links in protecting greenhouses from rain. It is necessary to select high-quality doors and Windows with excellent waterproof performance. The frames of doors and Windows should be made of materials with good sealing performance, such as aluminum alloy or plastic steel. Sealing strips should be installed between the door and window sashes and the frames to ensure there is no gap after closing.

Proper installation and sealing of doors and Windows: When installing doors and Windows, pay attention to the gap treatment between the doors and Windows and the wall. Use sealant to seal it to prevent rainwater from entering the greenhouse through the gaps. At the same time, the drainage holes of doors and Windows should be kept unobstructed to prevent rainwater from flowing back due to poor drainage.

Construction of outdoor drainage system

Ground drainage: Set up drainage ditches around the greenhouse. The depth and width of the drainage ditches should be designed based on the local rainfall and drainage requirements. The drainage ditch should maintain a certain slope, generally no less than 0.5%, to ensure that rainwater can flow smoothly to the drainage outlet.

Drainage pipe laying: Drainage pipes should be made of high-quality and corrosion-resistant materials, such as PVC pipes or cast iron pipes. The laying of pipelines should comply with the design requirements to avoid blockages or leaks. The connection points of the drainage pipes should be sealed with sealing rubber rings or glue to ensure that there is no leakage at the connection points.

Rain protection measures during the construction process

Material protection: During the construction process, materials such as glass and sealant should be properly protected to prevent them from getting wet or exposed to rain. Materials should be stored in a dry and well-ventilated place and covered with plastic sheeting or canvas to prevent them from being soaked by rain.

Temporary rain protection facilities: When encountering rainy weather, temporary rain protection facilities should be set up in a timely manner, such as covering the construction parts of the roof or walls with plastic sheeting or color steel plates to prevent rainwater from directly washing the construction parts and affecting the construction quality.

Timely drainage: During the construction process, if water accumulates inside the greenhouse, it should be drained promptly to prevent damage to the foundation and walls caused by the water. Water pumps or other drainage tools can be used to drain the accumulated water into the outdoor drainage ditches or pipes.
