Recently, many places in our province have encountered low temperatures, rain, snow and freezing weather, and snow and ice accumulation may crush trees, wires, and sheds, and the "ice skates" at high places may melt and fall, which may lead to the destruction of personnel and property, so it is very necessary to remove ice and snow in time.
What kind of method is used to clear snow and ice?
Heating method, flushing method and shoveling method are several methods that are more suitable for roof ice and snow removal, but the heating method and flushing method have certain limitations, and can only be used when the conditions are suitableThe more recommended method is the eradication method
Heating methodIf there is an air conditioner or other heating system in the room, the thermal conductivity of the steel structure can be used to promote the natural melting of snow by raising the indoor temperature. This method is more costly and less effective, especially for larger plants, which can be used before clearing ice and snow"Warm up".Dispose.
Flush methodFlushing the roof with a high-pressure faucet is a quick and easy way to do so. However, this method is only suitable for situations where the outdoor temperature is high and the snow cover is thin, otherwise it is easy to freeze, which will increase the load and cause collapse.
EradicationThe shoveling method is the most commonly used method of clearing ice and snow, which can be achieved by manual use of simple tools or by professional equipment. However, due to the certain risks of roofing, corresponding protective measures must be taken in the process of manual cleaning.
Precautions for clearing snow and ice
The principle of clearing snow and ice is:"First the heights, then the ground".。If there is ice accumulation at the construction site, the climbing operation should be suspended to prevent falling.
When clearing the roof of ice and snow, it should not be shoveled at will, and should be followed in general"From the cornice to the ridge, from the gables on both sides to the middle of the building, on both sides of the ridgeline at the same time, in order to clear in blocks".principles. If there are other snow piles such as high and low spans, elevator shafts, etc., on the roof, snow should be removed from these areas as a priority.
Security measuresSafety is the top priority, when clearing ice and snow, safety measures should be taken to prevent falling, cleaning personnel should be dispersed as much as possible, not concentrated in a purlin distance, and avoid stepping on weak places such as ridge covers, gutters, lighting panels, etc.; You should also pay attention to passers-by or ground workers to prevent dangers such as snow and ice falling.
Use the toolWhen clearing snow,Tools made of non-metallic materials such as wood or plastic should be used, hard metal tools can destroy the paint or plating on the surface of the roof panels; Chemical snow melting agents should not be used on metal roofs, nor should snow removal be carried out by sprinkling salt to melt snow, and the residues of these substances may also accelerate the corrosion of roof panels.
Other remindersIt should be avoided to clear a large area of snow at one time, and the snow should not be concentrated in one place on the roof, which can easily lead to uneven load and increase the probability of roof collapse; Do not transfer snow over other low-rise structures such as canopies, carports, etc., to avoid other indirect losses and injuries.
