What are the waterproofing standards and practices for grain warehouses?

Method:

First, take moisture-proof measures on the ground and use No. 10 construction petroleum asphalt. Use medium heat to boil asphalt and use two pots at the same time. One pot dissolves the asphalt filter residue; the other pot boils the asphalt to dehydrate it. The temperature control of asphalt boiling should be determined according to the asphalt model to prevent carbonization during asphalt boiling.

Then the ground base layer is processed. The base layer needs to be completely dry. It will take a long time to dry thoroughly. After the foundation project is completed, the soil should be filled and compacted immediately, and the three-component soil cushion layer should be laid. Build walls. The cushion layer must be dense, flat, protected, and painted evenly.

It is better to use a brown brush or a bristle brush for asphalt painting with pure asphalt. The specific operation method is to use an iron spoon with a diameter of 10 centimeters, and apply one to three times for each spoonful. Do not paint back and forth multiple times. It must be thin and even. Use about 4 kilograms of asphalt per square meter.

Put some desiccant to prevent moisture in the grains in the granary. Do not put anything around that is easily affected by moisture. Spread a few more layers of plastic, and then put desiccant directly under the grain.

Moisture-proof measures should be taken on the ground. The pavement layers should be made of 4 cm thick No. 150 plain concrete slabs. They can be precast or cast-in-situ. Each precast slab is 1 square meter. should. Use 1:3 cement mortar to set the grout. After laying the boards, use 1:2 cement mortar to smooth the joints.

Waterproof and moisture-proof construction of the wall base. The waterproof and moisture-proof construction of the wall base can be done by laying the feet in a stepping shape to prevent the pressure from the grain storage side from pushing the wall. Before painting the asphalt, the wall should be primed with 1:3 lime mortar, compacted and smoothed, then painted with a layer of asphalt, the thickness should be uniform, and finally a layer of lime milk should be painted on the surface.

How to make the corn barn waterproof and moisture-proof?

Answer: Place plant ash at the bottom of the corn bin to keep it from getting wet. This is a simple and easy solution. Plant ash has excellent moisture insulation effect. The specific operation method is: put about five centimeters of dry plant ash at the bottom of the corn bin, separate it with a plastic sheet on top of the plant ash, then put in the sun-dried corn kernels, leave a five centimeter gap at the top of the jar, then put in the grass and grass and cover it. , does not get wet up and down, and can also prevent insects and rats.

What are the construction requirements for granary exterior wall waterproof coating?

During the construction of waterproof coatings, attention should be paid to environmental changes. Different environments will have an impact on the film formation of waterproof coatings. Waterproof coating construction temperature requirements: Different coating types have different requirements for construction temperature, which should be controlled according to the temperature in the product description. Generally, it should be between 10 and 35°C, and the minimum temperature should not be lower than 5°C. When constructing paint indoors in winter, insulation and heating measures should be taken. Humidity requirements for waterproof coating construction: The relative humidity during construction is generally 60% to 70%. If the humidity If it is too low and the air is too dry, the solvent will evaporate too quickly and the paint will dry too quickly, resulting in poor conjunctival curing of the coating. However, it is also not suitable to construct waterproof coatings in high-humidity environments or rainy weather. Light requirements for construction of waterproof coatings: The construction site should have sufficient light, especially when color matching and color matching of coatings. If there is insufficient light, not only will the color be inaccurate, but also brush leaks and paint leakage will easily occur. Ventilation requirements for waterproof coating construction such as sagging: It is not advisable to carry out wall paint construction in windy weather. Excessive wind will accelerate the volatilization of solvent or water in the paint, resulting in poor film formation and easy contamination with dust, which affects the quality of the wall. Hygienic requirements for waterproof paint construction: the hygienic conditions of the painting site should be maintained in good condition, and the ground and air should be clean. Dust free. Otherwise, dust will fall on the coating, causing particles to appear on the surface of the paint film, which will reduce the smoothness and increase the workload of modification and polishing

What kind of waterproof coating should be used when water penetrates from the top of the warehouse?

Use two-component waterproof materials

(1) When using two-component waterproof coatings, component A and component B should be stirred evenly before preparation, and then strictly follow the materials The material mix ratio provided by the supplier must be accurately measured; the quantity of each preparation should be calculated and determined according to the coating area each time, and prepared as needed; when mixing, pour component A and component B into the container and use a portable electric Stir vigorously with a mixer until evenly mixed and ready to use.

(2) Before using the one-component waterproof coating, just stir it evenly before use.
