针对北方地区一些棚区温室冬季因积雪、风大、温室建造和管理上出现的坍棚造成经济损失甚至伤人事件,冬季日光温室生产有必要注意以下几个问题并加以预防。(1)检查加固进入冬季管理前,土墙结构日光温室墙体因自身的强度较低,因此要及时检查土墙体是否开裂、下沉和表层土层风化、流失。对已出现以上问题的墙体要用砖垛支撑和草泥垛墙及时加固。(2)调整校正支撑钢梁变形、开焊是造成棚室坍塌的主要原因。
Aiming at the economic losses and even wounding caused by the slump during the winter in some greenhouses in northern China due to snow accumulation, windy winds, construction and management of greenhouses, it is necessary to pay attention to the following problems and prevent them in the winter solar greenhouse production. (1) Inspection and reinforcement Before entering the winter management, the soil wall structure of the solar greenhouse wall should be checked in time for the cracking, sinking and weathering of the soil wall due to its low strength. Walls that have been experiencing the above problems should be reinforced in time with brickwork support and grass pasteurized walls. (2) adjust the support deformation of steel beams, open welding is the main reason for the collapse of the greenhouse.
