An inclined spherical concrete pipe manufacturing device and an inclined spherical concrete pipe produced by the same are provided to smoothly form inner and outer pipes of the concrete pipe with different diameters and to produce the concrete pipe in various shapes. The inclined spherical concrete pipe manufacturing device is composed of an outer pipe body(10) formed in the shape of a trapezoid of an inclined sphere, viewed from the section and composed of an inflow hole(11) formed on the vertical plane of the section to make the cement mixed with water, flow to the inside and an opening door(13) opened or shut by a hinge, especially opened from the inflow hole toward the lateral side; an inner pipe body(20) separated from an inner peripheral surface of the outer pipe body and inserted into the outer pipe body, formed in the shape of a trapezoid of an inclined sphere, viewed from the section, and provided with an inner pipe housing(21) integrally formed at the end to come into contact with the end of the outer pipe body; and a cover housing(30) installed at one end of the inner and outer pipe bodies to open and shut a space formed between the inner and outer pipe bodies and formed with a through-hole(31) in the center. |
