(l) The prestressed steel beam tensioning process is completed. (2) Cut off the exposed steel strands, and ensure that the exposed steel strands meet the design requirements. (3) Clean the impurities in the screw holes on the bearing plate. (4) Clean the cement slurry on the bottom of the anchor with a wire brush. (5) Install grouting tubes and vacuum tubes, ball valves and quick-change joints on the anchors at both ends. It is necessary to check and ensure that all installed valves can be safely opened and closed. (6) Marking the suction vacuum end and the pressure grouting end, wherein the suction hole on the suction vacuum end anchor seat is upward, and the grouting hole on the grouting end anchor seat is downward. (7) Before grouting, the holes shall be rinsed clean and wet. If there is accumulated water, it shall be removed by a hair dryer, and the anchor head shall be sealed, and the anchor shall be sealed without leakage. (8) Connect the upper end outlet of the three-way valve connected to the vacuum pump to the quick-change joint of the vacuum end with a high-pressure rubber tube. (9) Before the vacuum grouting is officially started, the vacuum pump is used to test the vacuum.
Pumtip micro diaphragm pumps and compressors are based on a simple principal, the circular power from the motor is converted into oscillating movement by an eccentric, which moves up and down its central point, this motion is then transferred to a diaphragm by means of a connecting rod, an elastic diaphragm, which in conjunction with an inlet and outlet valve creates a pumping action.
