Intermittent ventilation vacuum pre-pressure drainage system
The invention relates to an intermittent ventilation vacuum pre-pressure drainage system which comprises a drainage board (2), a horizontal drainage pipeline (1), a bowknot and a ventilation pipeline (3), wherein the horizontal drainage pipeline (1) is connected with a vacuum pump (17) through a water-vapor separation device (10). The drainage board (2) includes an upper drainage board and a lower drainage board which are connected and communicated through the bowknot, the drainage board mainly comprises a plastic core board, a grid portion (15) is arranged in the middle of the plastic core board, two sides of the plastic core board are respectively provided with a sealed hollow pipeline (11), the bowknot is connected with the upper drainage board and the lower drainage board and provided with a port (5), a port (20) and a plurality of ventilation pipeline ports (6), the port (5) is connected with the horizontal drainage pipeline (1), the port (20) is communicated with the inside of the bowknot, the ventilation pipeline ports (6) are connected with the ventilation pipeline (3), and a plurality of hollow ventilation connecting pipes (7) are fixedly arranged on two sides of the bowknot. Stability of vacuum degree in the drainage board can be ensured, and rapid and efficient drainage solidification can be performed.
