Waterproof construction process for joint of inner support upright post of foundation pit and bottom plate
The invention discloses a waterproof construction process for a joint of an inner support upright post of a foundation pit and a bottom plate, and relates to the technical field of building construction. According to the waterproof construction process, a double-sided self-adhesive waterproof coiled material is utilized for overlapping type waterproof system operation by virtue of a DAL wet laying method, so that problems of waterproof construction in a water environment are solved; the permeability of a cement-based permeable crystalline type waterproof material is utilized, so that self-sealing waterproofness in concrete is achieved; the watertightness of a watertight steel plate is utilized, so that waterproof construction quality is effectively ensured; an embedded galvanized steel pipe is utilized, and a water suction pump is externally connected, so that the influence of water pressure on poured concrete is reduced, and concrete pouring quality is improved; characteristics of micro-expanded impermeable concrete (or non-shrinkage impermeable concrete instead) are utilized, so that an interface of fresh and old concrete is further compacted.
