压膜边裤设置在前脸拐角处更好一些。而对于前脸没有明显拐角的棚室，压膜边裤的设置要低，但须注意不能让压膜绳将棚膜压到棚面钢丝上。
It's better to set the pressed edge pants at the corner of the front face. For the shed with no obvious corner on the front face, the setting of crimping trousers should be low, but it should be noted that the crimping rope cannot press the shed film onto the steel wire on the shed surface.
那么，目前棚膜大部分已经更换完毕，压膜边裤出现了过高或过低的情况如何处理呢？若是设置较高，就应做好排湿工作，可在压膜边河北立体车库 消防报警器塑料配件 电缆接地箱 电缆保护接地箱 塑料土工格栅 消弧线圈装置 裤下方设置与棚室同长度的收集器，可以是一半水袋折成V型，也可以是一半管道，然后将积攒的滴水排出棚室或引流到地膜下的土壤中。若设置过低，就需要在压膜绳与棚膜之间或棚膜与棚面钢丝之间垫上软料，减少对棚膜的磨损。
So, at present, most of the shed film has been replaced, and how to deal with the situation of too high or too low film pressing trousers? If the setting is relatively high, it is necessary to do a good job of moisture drainage. A collector with the same length as the shed can be set under the side pants of film pressing, which can be half of the water bags folded into V-shape or half of the pipes, and then the accumulated water will be discharged from the shed or drained to the soil under the mulch. If the setting is too low, it is necessary to pad soft material between the film pressing rope and the shed film or between the shed film and the steel wire on the shed surface to reduce the abrasion of the shed film
