用以代替铸铁雨水口箅子及井盖，可以减轻构件重量近30%，降低造价50%左右，可满 足汽?5重车荷载使用要求，并有效地解决了丢失问题。其外形尺寸为：箅子(长×宽×厚) 750×450×35mm，井盖Φ750mm和Φ650mm两种。该产品具有完整的设计及配筋图纸，成熟 的生产工艺，定型的及定点的模工单位和相应的模具加工图纸，有先进和设备选型，可代为 加工和购置配套设备。箅子可与S235建设部通用图的箅子框通用，井盖原则上按国际S147的 有关尺寸确定，井盖应与本设计匹配的井圈配套使用。
It can reduce the weight of components by about 30% and reduce the cost by about 50%. It can meet the requirements of heavy truck load and effectively solve the problem of loss. The overall dimension of the grate is 750 × 450 × 35mm (length × width × thickness), and two kinds of well cover are Φ 750mm and Φ 650mm. The product has complete design and reinforcement drawings, mature production technology, fixed and fixed mold units and corresponding mold processing drawings, advanced and equipment selection, which can be used for processing and purchasing supporting equipment. The grate can be used in common with the grating frame in the general drawing of s235 Ministry of construction. In principle, the well cover shall be determined according to the relevant dimensions of international S147, and the well cover shall be used together with the well circle matching the design.
