The application relates to the technical field of waterproof construction of building engineering, and discloses a waterproof structure at the interface between a temporary lattice column and a bottom plate of a foundation pit, which comprises a bottom waterproof layer, a fine stone concrete protective layer, a first-poured concrete bottom plate, an inner water-stop steel plate, an outer water-stop steel plate, a steel plate water-stop belt, post-poured expansion concrete and a grouting pipe; the waterproof structure is constructed into a bottom waterproof layer combined with sealing glue, inner and outer water-stop steel plates combined with water-swelling water-stop strips, a steel plate water-stop belt, post-poured expansion concrete, a pre-buried grouting pipe and other multi-channel waterproof measures, so as to form a complete waterproof system with prevention as the main part, multi-channel prevention and grouting remediation. The waterproof structure fully learns from the mature method of the post-poured water-stop joint, initiatively applies the post-poured water-stop idea to the waterproof structure of the interface between the lattice column and the bottom plate, and provides the waterproof structure at the interface between the temporary lattice column and the bottom plate of the foundation pit, which forms a multi-channel prevention system and has reliable waterproof effect.
