Greenhouse buried columns, can be divided into three steps, that is, first wiring, then set the "scale", and then buried columns in stages

1: lay out the cabling. For example, the inner diameter of vegetable greenhouse is 100 meters long. According to the field planning, the plot of 100 meters in length should be 3.5 meters in length (because 3.5 meters in length is not only good for vegetable plot preparation, but also can be planted with 5 ditches of vegetables, and can improve the overall bearing capacity of greenhouses) , plot can be planned out in the middle of 28 rooms, shed east and west of the two remaining 1 meter each of the two small. In accordance with this plan, respectively with tape measure the specific location of each room, and then north-south wiring

2: set a ruler. "scale" means a standard column used as a reference for other columns. In general, the Poles at the east and west ends of the shed are used as "rulers". In the case of a shed in Shouguang, Shandong province, if the wall behind the shed is 4.5 meters high, the available column heights are 5.5 m in the first row of reinforced columns (inclined to the north) , 5.8 m in the second row of reinforced columns (upright) , 5.5 m in the third row of columns (slightly inclined to the south) , 4.8 m in the fourth row of columns (inclined to the south) and 3.6 m in the fifth row of columns (inclined to the south)

The reason why the first two rows are weighted columns is that after the construction of the greenhouse, the area will bear the total weight of the roller and the thatch. After the column is selected, according to the wiring diagram, the two columns of the east and west of the shed can be buried. Note: the depth of the column is 60 cm. And, a row of columns to the north of some, so that the back wall of the oblique columns (commonly known as "Post") out of 40 cm, its angle with the horizontal line about 45 degrees, on the one hand, it is to improve the bearing capacity of a row of columns, on the other hand, it is to increase the sine hoin the shed in winter

3: separate columns. Take the "ruler" at the east and west ends of the shed as the standard, and bury the columns in order from ode to inside

Method: when burying a row of columns, measure and mark the position of 3 meters from the top of the column first. Then, in the "ruler" column (from its top down)3 meters from the east to the west to pull a line, column buried, the line and column 3 meters mark overlap. In accordance with this method, the fifth row of columns buried, buried within the various columns can be
