止を図９ながら効率よく運転するζとができる。The ∆ turn of the sediment discharge distribution in the sludge pipe changes as the sedimentation situation changes. Therefore, if the sediment discharge distribution is known, it is possible to detect the sedimentation status of the sludge pipe and efficiently operate the system to prevent sedimentation.

置でおる。That is, the present invention includes a density meter consisting of a transmitter and a receiver for detecting multiple levels of density t in a dredger's sludge removal pipe, a flow velocity needle consisting of a transmitter 4 and a receiver 1d for detecting flow velocities at the same multiple levels, and the same. A dredger discharge system that uses a calculation device that calculates the sediment discharge distribution in the pipe based on a single word detected by a current meter and a density meter, and a CRT display that graphically displays the flow velocity distribution in the pipe calculated by the calculation device. It is monitored by a device that monitors the distribution of sediment discharge inside the mud pipe.

限らない。The density meter 1 is, for example, a γ-radiation type density meter, and as shown in FIGS. They are arranged at a plurality of height levels with respect to the installed part, and the density at each height level is detected. In this case, it is preferable that the spacing between the transmitter a5 and the receiver 6 is narrower in the lower part and sparser in the upper part, where sedimentation is likely to occur in the drainage pipe 7. In addition, in the embodiment, the generator 5
Although the number of arranged receivers 6 is four, the present invention is not limited to this.

The installation is designed to detect flow velocities at multiple height levels. In this case, it is preferable that the transmitter 8 and the receiver (#69) are arranged sparsely in the upper part, except in the lower part where sedimentation is likely to occur in the mud draining pipe z. 8 and Uke 1
Although the number of arrangement with the d-device 9 is four, the present invention is not limited to this.

Add it to the A1 number, convert it to A/1), and send it to the S device 3. In the calculation device 3, the density and flow velocity are calculated 4 for each level to obtain the soil discharge behavior.Here, when the operating conditions of the dredger (discharge distance, 277 rotations) are constant, the true specific gravity of the soil is Since it can be regarded as uniform, the sediment discharge distribution is calculated from this sediment discharge distribution and the lff1lli in the sludge pipe. This result can be displayed on the CRT display 4, and the vertical axis can be
The position within g is displayed as a graph such as a broken line or an approximate curve with the horizontal axis as the local accent.

Therefore, if the arithmetic unit 3 generates an alarm signal in a certain range where the discharged soil approaches zero, and at the same time manually or automatically stops the swing win f, the dredging I ring can continue operating at a low gold mud rate. become. As a result, the sediment that was about to settle in g is washed away, and the pipe [, J] recovers.
