A sump structure is provided to secure resistance and bearing capacity by being supported strongly and naturally by a bottom concrete layer. The sump structure comprises a collecting well(10) manufactured in the various shapes or sizes according to the inflow rate of underground water, rainwater and waste water and equipped with a water collecting basin(12) opened upward, reinforcing members(16) placed on the outside of the water collecting basin at regular intervals, one or more coupling holes(18) formed on the surface of the reinforcing member and a flange formed on the top of the water collecting basin horizontally, and a mold(20) placed on the top of the water collecting basin of the collecting well and formed in the various heights according to the thickness of a bottom concrete layer. In addition, a seal is installed to a space between the mold and the collecting well, other open spaces or water leaking spaces, and a portion of the outside of the collecting well where water or concrete mortar leaks to the appointed thickness. |
