concrete delivery pipe fixed

Vertically upward piping, ground horizontal tube length less than a quarter of a vertical tube length and not less than 15m, or to comply with the requirements of the product manual. In the Y-shaped tube concrete pump discharge port 3 ~ 6m duct at the root should be set off valve to prevent reflux of concrete mixture.
Pumping underground structures, the ground should be horizontal tube axis and Y-shaped tube spout perpendicular to the axis. Asphalt Mixing Plant piping should be inclined tube top design exhaust valve; when the height difference is greater than 20m, should be in the lower end of inclined tube consists of five times the height of the horizontal pipe length; such conditions, increase the bend or coil meet five times the height length requirements.
Concrete pipes fixed, may not be directly supported on steel, formwork and embedded parts, horizontal pipe should be at a certain distance bracket, table mats, spreaders and Wheel Loader, in order to exclude the plugging assembly and disassembly and cleaning pipes; vertical embedded parts suitably fixed to the pipe walls and columns or leave holes at the top floor. In the walls and pillars, each section tube is not less than a fixed point in the hole should be set aside each floor fixed. The lower end of the vertical tube bends, should not be used as the anchor of the upper pipe. Should be established to withstand vertical tube steel support weight. When the vertical tube fixed on the scaffold when the scaffold may be needed for reinforcement. Clamp at the pipe joints shall not leak pulp.
