With this configuration, when muddy water (water is absorbed) from the central opening, the central opening on the upper surface of the mud collecting block is provided. A water flow along the upper surface of the mud collection block is formed in the periphery, and an effect that the sediment deposited on the upper surface of the mud collection block can be easily sucked is obtained.

Here, the upper surface of the rectifying cap is formed in an umbrella shape, a spherical crown shape, a flat plate shape, or the like, but is preferably in an umbrella shape or a spherical crown shape. This is because the precipitate deposited on the upper part of the rectifying cap is easily sucked into the central opening from around the rectifying cap. Further, it is preferable that the height of the rectifying cap on the upper surface of the mud collecting block can be freely changed by a screw or the like. This is because the resistance of the muddy water sucked from the central opening can be adjusted by changing the height of the rectifying cap. Therefore, by this, for example, by adjusting so that the height of the rectifying cap becomes higher as the distance from the place where the mud suction pump for sucking muddy water is connected, the height from the central opening of each mud suction block is adjusted.

It is connected to the connection port, and a muddy water pipe is connected to the discharge port, and the discharge end of the muddy water pipe is arranged to extend outside the sedimentation facility. In the sedimentation facility constructed in this way, the sediment deposits on the upper surface of the mud suction drain. Since the upper surface of the mud suction drainage device is formed concave toward the mud suction port, a large amount of sediment is deposited around the mud hole port. When the mud pump is started, the sediment deposited on the upper surface of the mud suction drain at the bottom of the sedimentation facility is sucked from each mud suction port, and discharged to the outside of the sedimentation facility through a water pipe and a mud suction pipe. (2) Since the muddy water (water absorption) is dispersed at multiple points, mechanical equipment such as a device for scraping the precipitate is not required. (3) Since muddy water (water absorption) is dispersed at multiple points, precipitates can be easily removed over the entire tank. (4) By discharging the sediment periodically with muddy water, high quality water quality is guaranteed. (5) It is not necessary to temporarily remove water during the work of removing the precipitate, and the number of man-hours for maintenance can be reduced. (6) Due to the dispersed water absorption, a large eddy current is unlikely to be generated even as upward water absorption, and there is no air suction by the eddy current, so that a high suction force can be maintained. (7) By making the upper surface of the mud collection block concave,
The local small vortex generated above the upper surface of the mud block by the flow generated in the sedimentation facility makes it easier for the sediment to be collected at the central opening by the Ekman laminar flow and Stewartson laminar flow, and facilitates the suction and removal of the sediment. . (8) Almost no maintenance and low running cost.

According to a ninth aspect of the present invention, there is provided the sediment discharging apparatus according to the eighth aspect, wherein the mud suction drainer is constituted by combining the mud collecting blocks according to the first to seventh aspects. The following operation is obtained by this configuration. (1) It is possible to lay a mud collecting block in conformity with the shape of the sedimentation equipment, and it is possible to easily perform the work by simply laying it on the bottom surface without changing the existing sedimentation equipment. (2) Since the mud suction drainage is blocked, workability in laying work is improved, and the construction period is shortened. (3) It is possible to apply from large equipment to small equipment.
