1 进料地坑设计目前进料地坑设计基本是采用钢板焊合箱体避水的方法,钢板焊合时,箱体如不留有足够高度,且没有使箱体埋进混凝土内,在春季多雨或梅雨季节,地下水位上升,水就有可能漫进地坑。同时,地下水压力也将挤压箱体,使之内鼓,导致箱体变形(我省数家种子公司安装后均出现了类似问题)。因此,进料地坑的设计应注意箱体焊合保持一定的 1 Feeding pit design Feeding pit design is basically the method of welding steel plate to avoid water, steel welding, the box does not leave enough height, and did not make the box buried in concrete, in the Rainy or rainy season in spring, the water table rises, the water is likely to diffuse into the pit. At the same time, groundwater pressure will also squeeze the box, so that the drum, causing the box deformation (several seed companies in our province after installation have similar problems). Therefore, the design of the feed pit should pay attention to keep the box welded to a certain extent
