Inspecting walls In order to prevent walls from being washed away by rain, vegetable farmers often use cover film, non-woven fabrics or measures to protect walls with cement or bricks. Some growers use large old films to cover the walls so that the rain will flow down and not soak the walls. However, the film ages quickly and is easily scratched. It is recommended that the vegetable grower choose the anti-aging film and put a layer of sunscreen material on the plastic film to reduce the sunlight. Usually pay attention to check whether the film is damaged, and repair it if it is damaged. After the shed wall is covered with non-woven fabric, in rainy weather, although the rain can wet the non-woven fabric, in the fine weather, the wall and non-woven fabric can be dried. The nonwoven fabric has a longer life than a cover material such as a film. The wall is covered with cement or bricks on the back wall, so that it can be protected from rain and heat, but it is relatively less expensive because it is relatively labor-intensive and expensive.
For old sheds, always check for leaks in the back slope. In places where water leakage has been found, it must be handled in time to repair the damage and ensure that the water is no longer leaked into the wall.
The height of the existing shed is higher than that of the new shed. The weight of the new shed is even more than six meters. The weight of the column itself and the weight of the insulation on the shed are also increasing. It is easy to create a column subsidence, which will affect the performance of the shed. The slab pillar is subsided, and the weight of the shed cover is too large. It is mainly caused by the loosening of the soil in the shed when the shed is built, and the sedimentation is caused by the downward subsidence after being pressed.
When it is found that the slab column is sunken, the soil at the base of the sag column can be completely removed, and then the two people hold the column and lift it upwards, so that the top of the column is in contact with the steel pipe accurately, and then immediately fill the bottom of the column to fill the slab and pad. Prevent the column from sinking again and finally backfill the soil around the column. If this is the case, it is best to check if the bottom of the column is covered with bricks. If not, the brick should be placed immediately after the column is lifted to effectively prevent the column from sinking.
