Abstract
The invention relates to a shallow point sweeping device and a shallow point sweeping method for a dredge boat. The shallow point sweeping device for the dredge boat is characterized by comprising drags arranged at the end parts of sludge sucking pipes on the left and right sides of the boat body of the dredge boat and a shallow point sweeping rope which is connected between the two drags and can fall onto water bottom under the action of gravity. Compared with the prior art in which the conventional drags used for sweeping shallow points is several meters wide and thus makes the fixing of the rope difficult, the shallow point sweeping device and the shallow point sweeping method have the advantages that: the transverse sweeping area of the shallow point sweeping rope is tens of times the width of the drags; the sludge digging and shallow point sweeping are performed at the same time; the cost is low; and the production efficiency is high.
Description
Technical field
The present invention relates to a kind of dredge boat with sweeping shallow device and method.
Background technology
Free floating suction dredge(r) is a kind of large-scale motor-driven dredge boat, during construction dredging tube is leaned to the bottom, and the dredging tube end is provided with drag head, utilizes mechanical force or the hydrodynamic force mud rake pine with the bottom, inhales mud by dredge pump then, by dredging tube input spoil hopper.When ship navigated by water forward slowly, its drag head was harrowed along the bottom to inhale and is dredged, referring to shown in Figure 2.
Owing to be subjected to influences such as wind direction, current, ship track and perfect condition have and necessarily depart from when the ship drag suction dredger is dredged; The drag head width is limited in addition, and the drag head track can not cover all dredging bottom surfaces; Bottom surface shale performance differs, and some surface of clay is smooth, and shearing force is big, and drag head can slide to the next door, so drag head is irregular at dredging bottom surface track.The point that some does not reach the construction depth requirement can appear in the dredging bottom surface, is referred to as shallow point.
When sweeping shallow the construction, the drag head drop point must be aimed at by the ship of rake suction in the past the summit of shallow some peak value, yet to aim at shallow point be not the part nothing the matter to a slight drag head in boundless sea, therefore sweeping shallow difficult point is the shallow point of drag head misalignment, be not easy to reach the standard grade, deep valley then occurs near the often shallow point, it is very many therefore inhaling ship institute's time spent in sweeping shallow work progress from the boat rake.Improving and sweep shallow efficiency of construction, is to improve from the boat rake to inhale one of important key of ship productivity ratio.
