摘要： PURPOSE:To raise the accuracy of construction work by a method in which an echo sounder is provided from the swinging direction of a suction head to each given direction to measure the top position of each sludge, the jumping height of the sludge, and distances from the seabed face. CONSTITUTION:Echo sounders 6F and 6B capable of measuring the distance of sludge 5 of the seabed from the sludge face are set at a distance of about 1m on front side F and back side B at almost right angle to the swinging angle S of a suction head 3, by which the depth of construction is detected. The depth of the head 3 in the sludge is detected by the sounder 6R provided ahead of the swinging direction S, and the jumping height of sludge 5 is detected by the sounder 6L provided in the back side. Since the finish face in the sounder 6L can be controlled on the basis of relationships of the measured values by the sounders 6B and 6L, the dredging performance can be raised by preventing incomplete dredging work and also minimizing the loss by overdredging.
摘要翻译：目的：通过以下方法提高施工工作的准确性：从吸头的摆动方向向每个给定方向提供回声测深仪，以测量每个污泥的顶部位置，污泥的跳跃高度和距离海床面。构成：能够测量海底污泥5与污泥面的距离的回波测深器6F和6B设置在前侧F和后侧B的大约1m处的距离与抽吸的摆动角度S几乎成直角头3，检测到施工深度。通过设置在摆动方向S前方的发声器6R检测污泥中的头部3的深度，并且通过设置在后侧的发声器6L检测污泥5的跳跃高度。由于可以根据发声器6B和6L的测量值的关系来控制发声器6L中的完成面，因此可以通过防止不完全的疏浚作业并且还通过过度疏浚来最小化损失来提高疏浚性能。

摘要： PURPOSE:To grasp exactly the advancing condition of dredging work by a method in which a gyroscope for detecting the swinging angles of a suction head is provided, an echo sounder is provided in a given direction from the swinging direction, and the dredging work amount is calculated. CONSTITUTION:Echo sounders 6F and 6B capable of measuring the distance of sludge 5 of seabed from the sludge face are set at the distance of about 1m on the front side F and back side B at almost right angle to the swinging direction S of a suction head, by which the depth of dredging work is detected. The swinging width is detected by a gyroscope 8 and the dredging amount is calculated from the detected values of swinging width and dredging depth. By detecting the swinging speeds of the head 3, the efficiency of dredging work can be known. Since the dredging amount can be soon obtained during the dredging work, the advancing condition of the dredging work can be determined to make the construction administration of the dredging work easier.
