    • In a system for dispersing stormwaters beneath the earth surface, a pair of arch shaped corrugated molded plastic chambers lie parallel each to the other upon a bed of gravel and are covered with soil. A bridge cover spans the space between the sidewalls of the adjacent chambers, to keep soil above from entering. Abutting base flanges establish the chamber spacing which fits the bridge cover and also protect the gravel at the bottom of the space from erosion. Stormwater is delivered to the space, to then flow through sidewall perforations into the chambers' interiors where it is stored and gradually dispersed into the earth. Debris settles in the pocket at the bottom of the space and is removed by a perforated pipe lying in the space. Chambers have high aspect ratios, of 0.8 to 1 or more, and steep sidewall angles, of less than 15 degrees.
    • 在用于将暴雨雨水分散在地表下方的系统中,一对拱形波纹模制塑料室在砾石床上彼此平行并且被土壤覆盖。 桥盖跨越相邻室的侧壁之间的空间,以防止土壤进入。 基座法兰建立了适合桥盖的腔室间隔,并且还保护了空间底部的砾石免受侵蚀。 雨水被运送到空间,然后通过侧壁穿孔流入室内,在那里储存并逐渐分散到地球中。 碎片沉入在空间底部的口袋中,并通过位于空间中的穿孔管道去除。 室具有0.8至1或更高的高纵横比和小于15度的陡峭的侧壁角。
