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.

Do grain silos need to be waterproofed?

Food is related to the country’s people’s livelihood. Therefore, for the safety of national grain reserves, granaries should have functions such as waterproofing, moisture-proofing, heat preservation, and air tightness. Therefore, waterproofing and moisture-proofing is key. If waterproofing is not done, after the grain is stored, the bottom or the corners and top of the silo will become damp or leak, which will increase the moisture content of the local grain and cause mold and agglomeration of the grain. cause losses.

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

Waterproof national standard?

1. There should be no leakage or water accumulation in the waterproof layer.

2. The materials used should comply with the design requirements and quality standards.

3. The surface of the leveling layer should be smooth and should not be loose, sandy or peeling.

4. The thickness, moisture content and apparent density of the insulation layer should meet the design requirements.

5. Structures such as gutters, eaves, flashings and deformation joints should meet the design requirements.

6. The rolling material paving method and overlapping sequence should meet the design requirements. The overlapping width should be correct, the joints should be tight, and there should be no wrinkles, bubbling or warping.

7. The thickness of the waterproof layer of the coating film should meet the design requirements, and the coating should be free of cracks, wrinkles, flow, bubbling and carcass exposure.

How to waterproof the interior walls of the granary?

Method:

Pure asphalt coating Asphalt uses brown brush or� Bristle brush as well. 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.

National standard for waterproofing?

The "Residential Design Code" (GB50096-2011) promulgated by the state stipulates that basements and semi-basements should take waterproofing, moisture-proof and ventilation measures, and lighting wells should take drainage measures. The roof, floor, exterior walls, and exterior windows of the residence should be able to prevent rainwater and melted ice and snow water from intruding into the interior.

National waterproof standard?

Waterproof standards are divided into four levels. The first-level waterproof standard means that no water can penetrate and the appearance of the structure has no moisture stains. First-level waterproofing is mainly aimed at key engineering projects. It usually uses three waterproof layers for defense. It is relatively long-lasting and can last for about fifteen years.

Level 2 waterproofing standards require no water leakage, but the structural appearance allows for less moisture stains. The third-level waterproof standard is that there are fewer water leakage points, but no line flow and mud and sand leakage are allowed. There are water leakage points at the fourth level, and no line flow or mud or sand leakage is allowed.

What are the waterproof standards for warehouse buildings?

For today's factories, there are usually warehouses inside the factory. These warehouses are for better storage of some products produced by the factory. During the storage process, if there is rainy weather, , there is water leakage in the warehouse, which will cause huge losses to our property. Instead of this, we should pay more attention to this aspect in our daily life and do a good job in waterproofing the warehouse. When there is water leakage in the warehouse on rainy days, we should pay more attention to this aspect in our daily life. Take remedial measures promptly.

In fact, for every factory, the most important thing is the warehouse. Just imagine: if the warehouse Once water leaks on a rainy day, it will cause serious losses to the profit value of our factory. If the loss is relatively large, we may lose all our money, so the waterproofing of factory buildings and warehouses is very important.

When constructing the waterproofing layer of the warehouse membrane, you should pay attention to the following points:

(1) Apply the base treatment agent on the base layer, which needs to be thin and even. After drying, the roll material can be laid only when it is not sticky to the hand;

(2) The roll material is waterproof and leak-proof. The paving of floors should generally be carried out from the lowest elevation of the floor upward parallel to the roof ridge, so that the membranes overlap in the direction of water flow. When the slope of the warehouse roof is greater than 10%, the membranes should be paved perpendicular to the direction of the roof ridge;

(3) Paving method: Peel off the isolation paper on the spine of the roll, and stick the roll to the surface of the base layer. The long side overlap of the roll should be maintained at 50mm, and the short side overlap should be maintained at 70mm. The roll is required to maintain a natural relaxed state. Edge sealing after hot melting;
