Construction method of medium-sized and small special-shaped hole embedded form boards in equipment foundation

The invention discloses a construction method of medium-sized and small special-shaped hole embedded form boards in an equipment foundation. The construction method comprises the following steps of S1, form board manufacturing, wherein foam boards are selected as form board materials, and the form boards are manufactured on site according to the drawing size; S2, form board pretreatment, wherein before the form boards are mounted, the outer surfaces of the foam boards are ground till friction faces are generated on the outer surfaces; S3, form board mounting, wherein the form boards are started to be mounted while foundation steel bars are mounted, the positions of the form boards are fixed, and concrete pouring is carried out after the form boards are qualified after checking; and S4, form board dismounting, wherein the form boards on the side walls of the equipment foundation are dismounted, roughening treatment is carried out on the surfaces of the form dismounting portions of an equipment foundation pier,
