    • A drainage system for use in concrete masonry unit (CMU) wall construction comprises a tray unit of a size corresponding to size of CMUs, to be received beneath a course of CMUs, in use. The tray unit comprises opposite side flanges to abut a superjacent CMU and supporting a pan therebelow. A strip of water permeable material is attached to an upper surface of the pan and extends transversely beyond a front edge of the pan. A block of water permeable material is positioned above the pan and extends upwardly into a hollow core of a CMU. The water permeable material of the strip and the block has a porosity sufficient to permit water to pass there through but substantially insufficient to permit mortar and debris to pass there through so that water in a hollow core of a CMU drains through the strip.
    • 用于混凝土砌块单元(CMU)墙体结构的排水系统包括在使用中将在CMU过程下接收的尺寸对应于CMU尺寸的托盘单元。 托盘单元包括相对的侧凸缘,以邻接上一个CMU并支撑下面的平底锅。 一块透水材料连接到锅的上表面,横向延伸超过锅的前边缘。 一块透水材料位于锅的上方并向上延伸到CMU的空心芯中。 条带和块体的透水材料具有足够的孔隙度,以允许水通过,但是基本上不足以允许灰浆和碎屑通过,使得CMU的空心芯中的水排出该条带。
