Use a metal or plastic pipe post-tensioned prestressed pipe pressure slurry

Prestressed pipe pressure slurry prestressed pipe pulp price prestressed pipe pressure paste manufacturers use a metal or plastic pipe channel of post-tensioned prestressed concrete structures or components, prestressed pipe pressure slurry shall meet the following requirements specifications, sizes of the pipeline 1 should comply with the regulations of design, and its cross-sectional area should not be less than 2 times of the prestressed steel net sectional area: pipe of length greater than 60 m, should be through the test to determine whether the area ratio can be normal prestressed pipe pressure slurry grouting operations. 2 pipes should be stipulated in the design of the coordinates of the location for installation, and should be used in positioning reinforcing steel bar is fixed, can make it firmly. At design position within the template, and does not produce displacement during concrete pouring. Pipeline with ordinary reinforced overlap, should move ordinary steel, may not change the design of the pipeline coordinates. 0 m; 8 m; On the curve of pipeline and flat corrugated pipe should be proper encryption. After positioning the pipe should be smooth, prestressed pipe pressure slurry its centerline and plate should be vertical. 3 pipeline connection pipe joint appropriate USES similar level of the diameter of the pipe, the length should be 5 to 7 times of the connected pipe diameter. Connection should not make joint Angle change and to move or shift of the pipe during concrete pouring, and shall be bound tightly to prevent infiltration of cement industry. Plastic corrugated pipe should use special welding machine for hot melt welding or using a sealing structure of plastic connectors. When using vacuum aided grouting technology for tunnel grouting pipe all the joints should be reliable sealing performance, and shall meet the requirements of vacuum degree. 4 all pipe shall be set in each vertex vent and set in each low drain when necessary. Grouting pipe and exhaust pipe and drain pipe should be the minimum inner diameter of 20 mm standard pipe or appropriate plastic pipe, and pipe should be used in the connection between the structure of metal or plastic fasteners, length should be sufficient to outside from the pipeline structure. After the installation of pipelines, prestressed pipe pressure slurry of reliable measures should be taken to the temporary plugging port, prevent or other debris into the water. The provisions of 1.
