A sediment removal type sewer structure of a public drainageway is provided to prevent rivers or sewage from being polluted or to prevent a sewer pipe from being clogged by accumulation of impurities by removing impurities contained in rainwater. The sediment removal type sewer structure of a public drainageway contains a rainwater pipe(10) buried under the ground(1) and connected to a coupling hole(21) of the collecting well to collect rainwater, a collecting well(20) connected to the rainwater pipe and equipped with a cover(23) exposed to the ground, a drainpipe(30) connected to the collecting well, a support bar(40) extended downward from the bottom of the cover and provided with longitudinal grooves(41) to couple an end of a fixing screw, a lift(50) coupled to the support bar to be liftable and rotatable, a fixing screw(60) coupled to the lift to fix the lift, a support(70) installed to the lift and composed of a support frame(71) coupled to a circumference of an opening of a filter bag, a pair of support rods(72) placed parallel to each other and hinged on upper and lower sides of the support frame at the front and upper and lower sides of the lift at the foundation and an extension bar(73) extended to the lower side of the support frame and provided with a caster(73a) adhered closely to the inner bottom of the collecting well, a filter bag(80) supported to the support and fixed closely to the inner side of the collecting well to cover the coupling hole of the collecting well with an opening to remove rainwater flew in the collecting well through the rainwater pipe, and a fixture(90) installed to the lift and composed of a fixing member(91) adhered closely to an inner side of the collecting well and provided with a caster(91a) and a pair of support rods(92) placed parallel to each other and hinged on upper and lower sides of the fixing member at the front and upper and lower sides of the lift at the foundation. |
