渫仕上シ海底面５へ土砂が埋め戻される現象が生ずる。Figure 1 is an explanatory diagram of the state in which soft ground 3 at the bottom of the water is being shallowly excavated by the cutter head 2 supported by the earth and sand dredging ladder 1 of a bong-type dredger, and Figure 2 is an explanatory diagram of the state in which it is being deeply excavated. In either case, during dredging, the original ground 4 collapses and the earth and sand scattered by the dredging cutter causes earth and sand to backfill into the seabed surface 5 of the finished dredged area.

いにはスイングウィンチが過負荷となシ、能率的な浚渫
作業が困難となる。This tendency is particularly noticeable when digging shallowly in sandy ground, and the backfilled soil 6 is gathered around the rudder 1 during the swing, eventually overloading the swing winch and making efficient dredging difficult. .
本発明の目的は上記埋め戻された土砂を吸い取る事によ
りスイングウィンチの負荷軽減を計ることができる土砂
浚渫装置全行るにおる。The object of the present invention is to provide an entire earth and sand dredging device that can reduce the load on the swing winch by sucking up the backfilled earth and sand.
本発明の土砂浚渫装置は、カッターヘッドを支持する土
砂浚渫ラダーの先端部両側に浚渫時埋め戻された土砂を
吸引する吸引機構を設けたことを特徴とする。The earth and sand dredging device of the present invention is characterized in that a suction mechanism for sucking earth and sand backfilled during dredging is provided on both sides of the tip of the earth and sand dredging ladder that supports the cutter head.
以下図面によって本発明の詳細な説明する。The present invention will be explained in detail below with reference to the drawings.
本発明においては第３図、第４図に示すようにラダー１
の先端部両側に吸入管７ｍ、７ｂ’を取シ付けその吸入
口を下方に向け、吸入管７ｍ。In the present invention, as shown in FIGS. 3 and 4, the rudder 1
Attach suction pipes 7m and 7b' to both sides of the tip of the 7m suction pipe, with the suction ports facing downward.
７ｂの出口を切換弁８を介してサンドポンプ９の吸入口

位置せしめる。The outlet of the sand pump 7b is connected to the suction port of the sand pump 9 via the switching valve 8, the outlet of the sand pump 9 is connected to the discharge pipe 10, and the outlet of the discharge pipe 10 is located near the suction port of the cutter head 2.
又、ラダーｌの先端両側に略矩形の集土板１１ａ、１ｌ
ｂｉカッターヘッド２に指向する方向に傾斜して取り付

内へ還元される。Since the earth and sand dredging device of the present invention is constructed as described above, during excavation and swinging of the seabed ground, the earth and sand backfilled to the rear of the cutter head 2 (on the earth collecting plate side) is easily removed from the soil plate 11a or llb.
Sand pump 9
The seawater is sucked together with seawater through the suction port of the suction pipe 7a or 7b connected to the cutter head 2 from the discharge port of the discharge pipe 10.
It is returned inward.

イングワイヤーのAs described above, according to the present invention, the load on the swing winch is reduced by removing the sediment that accumulates at the tip of the rudder. At the same time, efficient dredging is possible. At the same time, the bottom surface of the seabed is flat during dredging, and the swing wire
