It is generally applicable to buildings and structures where the pipeline passes through the wall and is vibrated or has strict waterproof regulations. If the casing is in the wall where it passes through the wall, it should be changed into a concrete wall if it meets a non concrete wall, and the casing must be poured into the concrete at one time. The use of this atlas should not only comply with the relevant technical requirements in the drawing, but also comply with the requirements of the current relevant specifications, procedures and standards. flexibility Waterproof casing The atlas is not only effective for pipeline engineering projects, but also suitable for civil engineering personnel.
   Flexible waterproof casing For the treatment of staggered platform and hanging curtain of interlayer joint and structural joint, 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 connection slope of the bottom plate of the diversion tunnel is 1:30 along the flow direction and 1:10 in the vertical direction.
The concrete surface peeling and damaged concrete surface peeling shall be treated by grinding. During grinding, attention shall be paid to smooth transition connection with the surrounding formed concrete until the surface is smooth and smooth. If a shallow pit is formed locally, it can be chiseled after large area 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 width of cracks. For cracks with total width less than 0.1 mm, it is proposed to brush teeth with steel wire within the scope of 20 mm along the cracks, and then clean the surface with acetone and apply a layer of epoxy based liquid for sealing treatment; When the crack width is 0.1 mm-0.2 mm, along the crack development direction, chisel a rectangular groove with a width of 80mm and a depth of 15mm-30mm. The length of both sides of the groove exceeds the length of the crack by 30cm, and then use epoxy mortar to smooth and compact. Flexible waterproof sleeve is a kind of hardware fitting which is suitable for the structure where the pipe passes through the wall and is subject to vibration or has strict waterproof regulations. The general manufacturing enterprises are manufactured according to S312, 02s404 standard atlas developed and designed by the Architectural Science Research Institute. If the wall where the flexible waterproof casing passes through the wall, it should be changed into a concrete wall if it is not concrete, and the casing must be condensed in the wall at one time; the flexible waterproof casing is widely used in construction, chemical industry, steel, drinking water, wastewater treatment and other units.
