Problems solved by technology

The substation accident oil pool includes a cylindrical side wall and roof. The formwork used in the process of pouring concrete is a circle formed by splicing small steel formwork. The surface of the oil pool poured with small steel formwork will appear More seams, uneven surface, affecting the strength of the oil pool
At the same time, the usual pouring process is that the side wall and the top cover of the oil pool are poured separately, which affects the integrity and strength of the oil pool

Embodiment Construction

[0030] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0031] The large formwork pouring construction method of the substation accident oil pool is characterized in that it includes the following steps,

[0032] A. Positioning and mold matching, select the appropriate template according to the size of the accident oil pool, determine the center of the accident oil pool, the position of the outer mold and the position of the inner mold; the centers of the outer mold 2 and the inner mold 1 are the center of the oil pool, and the outer mold 2 rings are set outside the inner mold 1.

[0033] B. Set the guide wall, set the circular inner mold guide wall at the inner mold position, and set the circular outer mold guide wall at the outer mold position; the inner mold guide wall and the outer mold guide wall are concentric, and the inner mold guide wall is set on the inner mold Inside the guide wall; the height of the guide wall...

Abstract

The invention discloses a large-formwork casting construction method for a transformer station accident oil pool. The method is used for casting the transformer station accident oil pool, and comprises the following steps of A, positioning and formwork matching; B, guide wall arrangement; C, inner formwork assembling; E, top formwork arrangement; F, concrete casting; and G, formwork dismounting. The method has the advantages that the oil pool can be cast and formed in a layered way; the single casting of a top cover is not needed; the integrality of the oil pool is improved; the formwork installation is simple, stable and firm; the cyclic utilization can be realized; and materials are saved.

Description

technical field [0001] The invention relates to a construction method for an accidental oil pool of a substation, in particular to adopting a large wooden formwork for pouring the accidental oil pool of a substation. Background technique [0002] The substation accident oil pool is used for the discharge of transformer oil during transformer accident maintenance. The substation accident oil pool includes a cylindrical side wall and roof. The formwork used in the process of pouring concrete is a circle formed by splicing small steel formwork. The surface of the oil pool poured with small steel formwork will appear More seams, uneven surface, affect the strength of the oil pool. At the same time, the usual pouring process is that the side wall and the top cover of the oil pool are poured separately, which affects the integrity and strength of the oil pool. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a large f...
