concrete pipes

Construction of the hot season, it is appropriate drop cloths wet, warm straw and other covered concrete pipes, avoid direct sunlight. Construction of the cold season, it is appropriate insulation material wrapped} Stationary conacrete plant, concrete pipes to prevent freezing, and to ensure the concrete into the mold temperature.
When the level of transmission distance over 200m, vertical transmission distance of more than 40m, pipes vertically downward or inclined tubes arranged in front of horizontal pipe, concrete mixes} Queensland unit cement content is less than 300kg/m3, the method must be selected piping and pumping process, it is appropriate large diameter concrete pipes and a long conical tube, pipe and hose less. When transporting concrete pump height exceeds the maximum transmission distance, the available pump Relay (successor pump) for pumping.
In addition, the project should be based on structural characteristics, construction techniques, ready mix concrete plant and piping, etc., choose the fabric device. Plane size should be based on structural, piping conditions and boom length, layout fabric devices, and its structure should be able to cover the entire screen, and can evenly and quickly for fabrics. Fabrics equipment should install solid and stable.
