The invention discloses an offshore soil texture seabed jetting disturbance device. A shallow layer jetting vehicle and a deep layer jetting hammer are included. A front shaft barrel and a rear shaftbarrel of the shallow layer jetting vehicle are hollow inside, and the bottom is provided with a plurality of rows of jetting holes. The two ends of each shaft barrel are provided with a rotation shaft, and walking wheels are arranged on the rotation shafts. The upper portions of the front shaft barrel and the rear shaft barrel are fixedly connected with a dragging bucket, balance weight blocks can be arranged in the dragging bucket, and the rotation shaft of the front shaft barrel is provided with a bracket capable of rotating around the rotation shaft. After a first water injection pipe is installed on the front shaft barrel and the rear shaft barrel based on a first water inlet hole, high-pressure water flow can be sprayed out of the multiple rows of jetting holes after entering the shaft barrels, and a seabed soil body is scoured. The interior of the deep layer jetting hammer is hollow, and a plurality of jetting holes are evenly arranged. A second water injection pipe is connected, the high-pressure water flow can be sprayed out of the multiple jetting holes after entering the deep layer jetting hammer based on the second water injection pipe, and the seabed soil body is scoured. According to the offshore soil texture seabed jetting disturbance device, through combined application of the shallow layer jetting vehicle and the deep layer jetting hammer, the seabed soil bodyin the large depth range can be disturbed and damaged, and later penetration construction of a torpedo anchor or a barrel-shaped foundation is facilitated.
本发明公开了一种一组近海土质海床喷射扰动装置,包括浅层喷射车和深层喷射锤;浅层喷射车的前、后轴桶内部中空、底部设置多排喷孔,轴桶两端设置转轴,行走轮安装在转轴上;前、后轴桶上部与拖斗固定相连,拖斗内可安放配重块,其中前轴桶的转轴上安装有可绕其旋转的托架;前、后轴桶基于第一进水孔安装第一注水管后,高压水流进入轴桶内部后可从多排喷孔中喷出,冲刷海床土体;深层喷射锤内部中空,均匀设置有多个喷孔;连接有第二注水管,高压水流基于第二注水管进入深层喷射锤内部后可从多个喷孔中喷出,冲刷海床土体。本发明浅层喷射车和深层喷射锤的组合运用,能将较大深度范围内的海床土体扰动破坏,便于后续鱼雷锚或桶形基础的贯入施工。
