The invention discloses a
pile foundation construction platform and hanging box bottom plate integrated structure and a construction method, and belongs to the technical field of
pile foundation construction.The construction method specifically comprises the following steps that S1, a construction platform is erected, a plurality of temporary supporting piles are driven into a preset installation position, and an integrated platform bottom plate structure is erected on the tops of the temporary supporting piles; s2,
pile foundation construction is conducted, specifically, pile forming construction of all
engineering piles is conducted on the integrated platform bottom plate structure; s3, side plates are erected, specifically, the side plates are erected on the top of the integrated platform bottom plate structure; s4, the platform is lowered, the formed hanging box is hoisted, connection between the temporary supporting piles and the integrated platform bottom plate structure is removed, then the temporary supporting piles are removed, and the formed hanging box is hoisted and lowered to the designated position of the
engineering pile; and S5, bearing platform construction is conducted, sealing treatment is conducted on gaps of the hanging box, then
water pumping is conducted on the hanging box, and pouring of the bearing platform is achieved in a layered mode. The method has the effects that the construction period of bearing platform forming is shortened, and the construction efficiency is improved.
