A sinking prevention structure of a sewerage is provided to prevent the separation of the side plate caused by the ground sinking by fixing the second anchor body and the side plate by the wire. A sinking prevention structure(700) of a sewerage is composed of first and second anchor bodies(140,150) arranged in two lines at both sides of the width direction mounted with a hume pipe(120) along the longitudinal direction of the upper surface of a concrete bottom plate(100); a side plate(300) having plural first anchor holes(310) inserted at the outer second anchor body laid in two lines of the width direction of the concrete bottom plate and longitudinally installed, the anchor hole shaped like a cylinder and vertically formed at the lower surface, a side hole(320) horizontally penetrated to penetrate the upper side of the anchor hole, and the second anchor hole obliquely formed to penetrate the width direction of the rectangular plate to the upper surface formed with the first anchor hole; a wire(200) installed to prevent the separation of the plural side plates by longitudinally penetrating the side hole where the second anchor body is inserted at the first anchor hole of the side plate to horizontally penetrate the upper side of the anchor hole and a circular hook(152); and an anchor(400) as a member where an upper end of a vertical rod is bent, and integrally formed with a bent rod, where the first anchor body is inserted at the inner peripheral surface of the vertical rod and the bent rod penetrates a second anchor hole(330) of the side plate, and laid to be supported by the clay and the original ground put at the upper part of the hume pipe. |
