There are many vegetable farmers who have built new sheds this year, but due to lack of experience, many farmers have experienced problems after erecting columns. Master Wang of Lijia Village, Jitai Township, Shouguang City built a 100-meter shed this year. After the construction, it encountered a rain. After the rain, Master Wang found that the last row of columns had problems such as tilting back and sinking. Some even broke. Reporter analysis believes that this situation arises because it was not established when the column was erected. The upper part of the column is fixed. Many vegetable farmers have replaced their skeletons with steel skeletons. Compared with the former Da Zhu Qi, the steel tubes are smooth and the bearing area is small. Moreover, some greenhouse steel tubes and pillars are not at an angle of 90 degrees. If the lower part is not firmly fixed, The upper part can easily trip in the direction of the wall. Even if it is fixed by the wire, there will be room for movement. In order to avoid the slipping of the upper part of the pillar and the steel pipe, a steel pipe with a length of about 10 cm may be welded on the steel pipe. The steel bar is vertically downward and is inserted into the round hole in the middle of the pillar. Then the steel wire is bundled and fixed. This avoids the front and rear activities of the column. The next step is to base the labor force on the base. It can be said that many columns in the shed are directly erected into the pits, and there are no bricks or other things on the bottom, so it is easy to cause sagging due to the excessive pressure on the upper part. Many of the sheds were crushed by heavy snow this year. One of them was that the weight of the snow was too heavy and the columns had fallen. When the column is erected, it must be compacted while burying it. The column in the king's shed is not in its original position. It is because when he erected the column, he buried the soil and compacted it. Strong, but soft with water. Therefore, when erecting the column, one must add a brick or a large area of ​​hard objects to the bottom of the pit to increase the area of ​​stress. Second, when burying the soil, it should be compacted while burying and avoiding the situation of real deficiency.
