The invention discloses a drainage-type
muck pond and a multi-dimensional seepage and
dehydration method of earth-pressure-balance shield
muck. The drainage-type
muck pond comprises a pond base used for being loaded with the muck, a sealing structure is arranged in an opening of the upper portion of the pond base and used for sealing the pond base fully loaded with the muck and making an pond baseinner cavity loaded with the muck be sealed, a bottom
pipe network used for collecting water seeping downward from the muck from the lower portion is arranged on the bottom of the pond base inner cavity, and a suction and drainage device is connected onto the bottom
pipe network, wherein the suction and drainage device is used for sucking outward the water collected in the bottom
pipe network andmaking the balanced negative pressure be formed in the sealed cavity so that water in the muck can be forced to seep outward fast. Through the action of the vacuum negative pressure, drainage of themuck to the surrounding and the bottom is forced, and
moisture which enters a channel of the suction and drainage device is sucked by the suction and drainage device for being drained outward, so thatthe
water content of the muck in the sealed space is lowered, harmless treatment is achieved, and a foundation is laid for
resource utilization; the method is suitable for
dehydration treatment of all shield construction muck and muck with
high water content.
