The utility model discloses constitute by bottom surface waterproofing membrane 1 and half cylinder facade waterproofing membrane 2 as an organic whole each other. Wherein, a side of the bottom surface waterproofing coiled material 1 is provided with a semicircular gap, the root of the semicircular vertical surface waterproofing coiled material 2 is connected with the edge of the semicircular gap, and the semicircular edge of the root of the semicircular vertical surface waterproofing coiled material 2 is coincided with the edge of the semicircular gap. The shape of the other side of the waterproof roll material 1 is not limited, such as an arc shape or other polygonal shape.
the invention is described in further detail below with reference to the drawings and the specific examples, which, however, should not be construed as limiting.
Example one
The embodiment is a pipeline fitting, which is used for sealing and waterproofing between a pipeline (such as a toilet sewer pipe or a basement wall-penetrating pipeline) and the ground (or a wall surface). The waterproof coiled material is generally used for the construction of pipelines in indoor places or wall-through pipelines in basements.
As shown in fig. 1 and 2, the present embodiment is constituted by a flat waterproofing membrane as a bottom waterproofing membrane 1 and a semi-cylindrical facade waterproofing membrane 2 which are integrated with each other.
