Introduction: Flexible waterproof sleeve is used when the pipeline passes through the wall under vibration or buildings with strict waterproof requirements. Most of the wall structure is concrete structure, so the casing must be poured into the concrete at one time during installation. When using this atlas, divide

When the pipeline crosses the wall and is subject to vibration or buildings with strict waterproof requirements, flexible is adopted Waterproof casing Most of the wall structure is concrete structure, so the casing must be poured into the concrete at one time during installation. The use of this atlas should not only comply with the relevant technical standards on the drawing, but also comply with the requirements of relevant standards, procedures and standards. Flexible waterproof casing The atlas is not only useful for pipeline engineering, but also suitable for civil engineering personnel.
Treatment of staggered platform and hanging curtain for interlayer and structural joints of flexible waterproof casing, the slurry leakage hanging curtain formed by staggered platform shall be removed firstly, and then the position formed by staggered platform shall be polished. In order to ensure the smooth connection between the polished concrete surface and the nearby concrete, the side wall and arch top of the diversion tunnel are 1:20 and 1:10 respectively; the convergence slope of the bottom plate of the diversion tunnel is 1:30 along the flow direction and 1:10 in the vertical direction.
The peeling of concrete surface and damage of concrete surface shall be treated by grinding. During grinding, the smooth transition connection with the surrounding formed concrete shall be paid attention to until the surface is smooth and smooth. If some shallow pits are formed, they can be chiseled after large-scale polishing and grinding, and the deep layer should be no less than 2cm, and then the epoxy mortar should be used to smooth and compact.
The flexible waterproof sleeve is generally applicable to the buildings where the pipeline crosses the wall and is subject to vibration or has strict waterproof requirements. If the casing is not concrete wall, it should be changed into concrete wall, and the casing should be poured into the concrete at one time. The use of this atlas should not only comply with the relevant technical standards on the drawing, but also comply with the requirements of the current relevant standards, procedures and standards. Flexible waterproof casing atlas is not only useful for pipeline engineering, but also suitable for civil engineering personnel.
When the concrete surface molts and damages the concrete surface, the grinding method shall be adopted. During grinding, the smooth transition connection with the surrounding formed concrete shall be paid attention to, and the surface surface shall be smooth and smooth. If a shallow pit is formed locally, it can be chiseled after large-scale polishing and grinding, and the deep layer should be no less than 2cm, and then the epoxy mortar should be used to smooth and compact. The treatment of shallow cracks and chemical grouting cracks can be divided into shallow cracks and deep cracks according to the crack width. For the cracks with total width less than 0.1 mm, it is proposed to brush the surface with steel wire brush within 20 mm of the crack, and then clean the surface with acetone and apply a layer of epoxy based liquid for sealing treatment; When the crack width is between 0.1 mm and 0.2 mm, along the crack development direction, chisel a rectangular groove with width of 80mm and depth of 15mm-30mm. The length of both sides of the groove exceeds the length of the crack by 30cm, and then the epoxy mortar is used to smooth and compact
