The invention provides a construction method for an inverted conical shell structure. A horizontal structure and a vertical structure on the lower part thereof are separately constructed, wherein the vertical structure which is well constructed beforehand is used as a supporting base for a templet bent frame on the bottom of the horizontal structure; after concrete is cast on the horizontal structure and is pressed and impacted, the ringent part of the surface of the horizontal structure is sealed to prevent concrete from overflowing from the ringent part of the surface of the horizontal structure when the upper vertical structure is cast by the concrete; and finally the upper vertical structure is cast, therefore, the problem that the geometric dimension of the horizontal structure and the compactibility of the concrete can not be guaranteed is solved, the construction joints are reduced, and the construction period is shortened.

The invention relates to the technical field of building construction, in particular to a construction method for resisting artesian water in a bottom plate pit of a foundation pit. The invention discloses a construction method for bottom plate pit backfilling sand ballast. The method comprises the following steps of: a, after a bottom plate is cast and reaches the designed strength, clearing garbage and accumulated water in the bottom plate pit so that the bottom plate pit is clean and tidy; and b, backfilling the backfilling sand into the bottom plate pit till the surface of the foundation pit. According to the construction method for the bottom plate pit backfilling sand ballast, the integral weight of the bottom plate is increased by piling yellow sand in the bottom plate pit to resist the artesian water, so that the water pumping quantity of the artesian water is reduced, the influence on the surrounding environment is reduced, and risk on the surrounding environment is effectively ...
