預制化糞池模具生產的內部中空,使用的時候,必需要裝沙土和水,來起到防撞的作用,同時塑料的特性是輕便移動。從而內部裝水是好的選擇,因為在使用完框格護坡模具 箱體護坡模具 華爾街銅牛 電阻柜 接地電阻柜 電纜保護接地箱 隔離墩模具 化糞池模具以后,水可以快速放掉,然后移動到下一個需要的地點。而內部裝沙土,其沙土的價格比水貴,并且在導出沙土的時候,也會比較麻煩。
The interior of the prefabricated septic tank mold is hollow. When it is used, it must be filled with sand and water to play the role of anti-collision. At the same time, the plastic is characterized by light movement. Thus, internal water is a good choice, because after use, the water can be quickly discharged and then moved to the next required place. The price of internal sand is more expensive than that of water, and it will be more troublesome when exporting sand.
