Drainage plate for intermittent breathable vacuum pre-pressure drainage
The invention relates to a drainage plate for intermittent breathable vacuum pre-pressure drainage. The drainage plate comprises an upper drainage plate, a lower drainage plate and a butterfly knot, the butterfly knot is connected between the upper drainage plate and the lower drainage plate, the structure of the upper drainage plate is as same as that of the lower drainage plate, both the upper drainage plate and the lower drainage plate mainly comprise plastic core plates, a grilling (15) is arranged in the middle of each plastic core plate, closed hollow pipelines (11) are formed in two sides of the plastic core plate, the butterfly knot is provided with an end port (5), the end port is connected with a transverse drainage pipeline (1) and penetrates the butterfly knot, an opening (20) communicated with the inside of the butterfly knot is formed inside the butterfly knot, two mutually independent ventilation pipeline end ports (6) are formed in the upper portion and the lower portion of the end port (5) penetrating the butterfly knot and connected with ventilation pipelines (3), and hollow ventilation connecting pipes (7) are fixed on two sides of the butterfly knot close to the upper end and the lower end. The drainage plate can make contributions to independent running of a drainage pipeline network and a ventilation pipeline network.
