Original roof pipeline waterproof structure of reconstruction project and construction method thereof

Abstract

The invention discloses an original roof pipeline waterproof structure of a reconstruction project and a construction method thereof, and belongs to the technical field of roof waterproofing. The original roof pipeline waterproof structure of the reconstruction project comprises a pipeline passing through a roof sheathing; the pipeline is sleeved with a waterproof sleeve, and the roof sheathing isprovided with a mounting through hole just allowing the lower end of the waterproof sleeve to pass through; a fine aggregate concrete layer surrounding the periphery of the waterproof sleeve is arranged on the upper end face of the roof sheathing; the lower end side of the waterproof sleeve is fixedly sleeved with a wing plate, an outer edge groove is formed in the upper portion, corresponding tothe mounting through hole, of the roof sheathing, and an outer edge groove of the roof sheathing is filled with concrete materials used for burying the wing plate; an asbestos cement joint and linenfilling layer is filled between the pipeline and the waterproof sleeve, and a sealing element is arranged between the upper end of the waterproof sleeve and the pipeline. The construction method comprises the following steps of manufacturing the waterproof sleeve, punching, mounting the waterproof sleeve, arranging the fine aggregate concrete layer, performing a water storage test and then mounting the pipeline. The waterproof structure has good waterproof performance, and the stability of the waterproof structure can be well guaranteed.

Description

technical field [0001] The invention relates to the technical field of roof waterproofing, in particular to an original roof pipe waterproof structure of a renovation project and a construction method thereof. Background technique [0002] At present, in most buildings, pipes often need to extend out of the roof, and the place where the pipes pass through the roof is relatively weak, which may easily lead to problems such as water seepage. Therefore, it is necessary to improve the waterproof performance of the connection between the roof and the pipes. Contents of the invention [0003] 1. Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide a waterproof structure and construction method for the original roof pipe of the renovation project, which has better waterproof performance and can better ensure the stability of the waterproof structure. [0005] 2. Technical solution [0006] In order to solve the above...
