What are the preparations for the construction of a greenhouse?

1： Wall protection

The three walls of the vegetable greenhouse form its structural framework, which is also the key to the firmness and insulation of the greenhouse. For the newly-built greenhouses, although chain rail cars are used for rolling in the stacked walls and excavators are used to cut the walls in the greenhouses, the inside and outside of the three walls will be washed by rain in rainstorm and other weather conditions due to loose soil and large slope, and even some walls will collapse in serious cases.

2： Rust prevention

Nowadays, most newly built greenhouse greenhouses use galvanized steel pipes inside and outside as the "skeleton" material for the greenhouse. However, the steel pipes sold on the market are mostly 6 meters each, and the span of the greenhouse is more than 10 meters. Therefore, shantytowns weld two steel pipes of the same size (mostly 1 and a half inch steel pipes) together for use. Little do they know that the steel pipes will damage the galvanized layer during the welding process.

3： Drainage of floods and waterlogging

When constructing a new greenhouse, the soil in front of the greenhouse is mostly used up, but compared to the surface inside the greenhouse, it is still relatively high. If the rainy season comes, it is very likely that rainwater will irrigate the greenhouse. Excessive rainfall and accumulated water in the shed can cause the pillars inside to sink; The second is that it will soak the roots of three walls, both of which are highly harmful. Therefore, I suggest that shantytowns should do a good job in flood control during the rainy season.
