Description of the Related Art Generally, in areas without public sewerage facilities, wastewater discharged from houses and factories must not be discharged into public waters unless it is purified. Therefore, a septic tank is required, but a general septic tank is composed of a septic tank, an oxidizing tank, and a disinfecting tank, and the filth flowing together with the washing water is digested and decomposed by anaerobic microorganisms in the septic tank. It liquefies and partially gasifies. The liquefied part is digested and decomposed by aerobic microorganisms in an oxidation tank, and the treated wastewater is finally disinfected in a disinfection tank and discharged into public waters.

付カサアゲ管体。1. A body-side rising frame for framing a plurality of manholes provided on an upper surface of a septic tank installed horizontally so as not to have a problem caused by burying the septic tank body at an angle.
A male-female helical tube, which is a male-female helical tube interposed between a manhole cover mounting frame for freely opening and closing the respective manhole covers and fixing the periphery thereof by concrete when embedded, Place a universal joint made of resin on the upper end of the spiral cylinder,
An inexpensive inner spherical bulge blow-molded from a heated raw tube, and a socket for the female spiral cylinder spigot formed on the anti-sliding side of the inner spherical bulge. And an inexpensive outer spherical swelling body which is slidably fitted to the inner spherical swelling body and blow-molded from a heated raw tube, and a non-sliding side of the outer spherical swelling body. An outer flange formed integrally with the outer flange for mounting the manhole cover mounting frame and an outer fold provided at a sliding side end of the outer spherical bulge for preventing deformation of the outer spherical bulge; After adjusting the height and the inclination of the manhole cover with respect to the ground surface, a concrete is formed around the main body-side rising frame, the male / female spiral cylinder, the universal joint, and the manhole cover mounting frame. The universal joint whose inclination has been adjusted by winding it, and which has the strength to withstand the static road load of passenger cars. With Le lid universal joint raising tubes - septic tank for sailing that.
