Problems solved by technology

At present, the main sealing method is to use waterproof cement mortar for sealing. After the waterproof cement mortar is solidified, it cannot be completely adhered to the original material, and the seepage path of groundwater is not effectively blocked from the source, so the waterproof effect is poor.

Abstract

The invention discloses a rigid through-wall pipe plugging structure and a construction method thereof. The rigid wall through-wall pipe plugging structure comprises a rigid wall through-wall pipe pre-embedded in a structural outer wall, and a water-swellable filler is hermetically arranged in the rigid wall penetrating pipe. The construction method of the rigid through-wall pipe plugging structure specifically comprises the following steps: the rigid through-wall pipe is pre-embedded in the structural outer wall, and after the rigid through-wall pipe is used, corrosion and sundries in the rigid through-wall pipe are removed; the water-swellable filler in hermetically arranged in the pipe, on the upstream face of the structural outer wall, wherein the water-swellable filler comprises a first anti-corrosion wood anvil, a water-swellable water stop strip, elastic polyurethane and a second anti-corrosion wood anvil. The rigid through-wall pipe plugging structure and the construction method thereof can effectively prevent underground water from leaking into the underground structure from the plugging position of the rigid through-wall pipe.

Description

technical field [0001] The invention relates to the technical field of underground engineering waterproof construction, in particular to a rigid wall-penetrating pipe sealing structure and a construction method thereof. Background technique [0002] Waterproofing of underground structures has always been an important technical problem in the field of civil engineering construction, especially in areas with abundant groundwater or high groundwater levels. The waterproof effect of the water-facing surface (face facing the water) of underground structures is directly related to the use function and structure of the building. security. [0003] Due to the needs of construction measures, during the construction process, the outer wall of the underground structure often needs to pre-embed small-diameter rigid wall-penetrating pipes in the wall, and the rigidity of the small-diameter pipes used for these construction measures is required in the later stage of structure fabrication....
