PVC Pipe Extrusion Machine
Pe pipe in municipal water supply and drainage works is mainly divided into slotting and trenchless varieties of construction methods, these days pe pipe producers specially from slotting production techniques.
(1)Pay attention to the specification of pipeline laying according to relevant regulations, and inspect in accordance with the product standard to eliminate the pipes that do not conform to the standard. If the pipe is laid under the carriageway, the thickness of the soil on top of the pipe should not be less than 0.7 m. If you need to pass through obstacles, the installation of steel and other production of protective casing. The pipe should be laid in a straight line. If the flexible joint is needed, the angle of the longitudinal axis should not be more than 2 ° . When the buried depth of the pipeline is lower than the base of the building, the pipeline should not be laid in the pressure area of the foundation diffusion angle under the building foundation. When the ground water level is higher than the height of the bottom of the trench, the measures of lowering the ground water level should be taken to prevent the instability of the trench.
(2) Pe pipe with specific tension should be selected consistent with the external environment.
(3) When the trench is excavated, the width of the ditch bottom of the pe pipeline should be decided fairly, that is according with the construction guidelines, that allows you to carry out manual work. inside the procedure of creation, the groove shall no longer be overdug. if the overdug isn't careful, herbal graded sand and stone materials will be used for filling. the grain length of the stuffed sand and stone must be between 10 mm and 15 mm, or the most grain size have to be much less than forty mm.
(4) Sand cushion foundation is used for pipeline basis. grooves should be reserved on the interface to facilitate the operation of the interface. after the construction of the interface, the pipe have to be full of sand. for the general soil phase of the inspiration is only a layer of zero.1 m thickness of sand cushion. if it's far a soft soil foundation and the lowest of the trough is placed below the groundwater level, it's miles really useful to lay a layer of gravel basis no longer much less than 500px thick.
