After the sheds are built, it is common for the sheds to collapse. Careful farmers will find that the collapse of the shed wall began after the brick shed. Obviously, it is of utmost importance to do a good job of protecting the building after the shed. During the investigation, the reporter learned that there are many reasons for causing the collapse of the shed after construction. It is necessary to find protective measures that are targeted to the cause. Let's analyze it. First, there is a hole in the plastic film that is used to wrap the grasshopper or corn stalk after wrapping it in the greenhouse. When constructing sheds, some vegetable farmers have to save the cost of building sheds, and often use some old sheds to wrap straw or corn stalks. Many of these old shed films often have holes in them, that is, when they are wrapped with a multilayer film, it is still difficult to avoid getting into moisture. As a result, grass pods and corn stalks are very likely to rot and age, and the load-carrying force drops, resulting in collapse. Therefore, when building a shed, it is necessary to use a new film to wrap the grasshopper and corn stalk tightly, and then it is better to cover it with a layer of plastic foam board to enhance the moisture resistance. Do not save two small money and cause serious losses. Secondly, after the shelter, the back slope of the outside of the building did not protect the rain. For the back slope behind the greenhouse, the vegetable grower often puts a layer of film on it for rain protection, that is, it uses a new film. After long-term use, it will inevitably lead to broken holes and leakage of rainwater, causing the collapse of the building. Therefore, when constructing a large shed to cover soil on the back slope, it is better to incorporate not less than one-third of the lime powder on the surface of 20 cm of soil so that the back slope will not leak. Then the soil on the shed wall where the cement slanting column is placed should pay attention to compaction. After the cement slanting columns are erected, the gravity is very large. If the soil on the wall of the shed is not compacted, the soil is loose, and the pressure of the slanting column cannot be accepted, and the brickwork is easily collapsed. Therefore, the soil here must not only be compacted, but also be tiled below the inclined column to increase its stability. In addition, rodent damage is also an important reason for the collapse of the post-laying. After the laying of grasshoppers and corn stalks, it is easy to drill into the rats, causing rainwater to infiltrate from the rat hole, resulting in rot of grasshoppers and corn stalks, which led to the collapse of the rear bricklaying. Therefore, the rat hole that appears on the back slope of the greenhouse must be blocked in time to prevent it. Conditional vegetable farmers prefer to use cement boards instead of straw and corn stalks to deal with rat damage.
