Abstract

This application relates to the technical field of pipeline seepage prevention, and in particular to a seepage prevention node structure at the root of a pipeline in a basement roof slab. The structure includes a floor slab, a waterproof sleeve inserted into the floor slab, and a pipeline inserted into the cavity of the waterproof sleeve. The floor slab includes a waterproof layer, one end of which is connected to a first additional waterproof layer, and the other end of which is connected to the top surface of the waterproof sleeve. A reinforcement layer is provided on the top surface of the floor slab, which covers the first additional waterproof layer, thereby improving the waterproofness between the floor slab and the pipeline.
