For solving the problem of the dredging silt from fishpond bottom, a silt-dredger with the underwater walking ability is developed and its main implements are the diving type mud pump and screw propeller on the low specific pressure buoy.
本文介绍了针对精养鱼塘清淤问题而研制的一种潜走式池塘清淤机。
Try in make clear, hydraulic pressure shovels dredger, grab bucket to shovel dredger construction efficiency instead instead taller, dredge of dredger of grab bucket type shovels type dredger to affect degree small; to wring dredger suction type to water environment than turning over, contain a lot ofas a result of bottom mud sundry, suction inlet jams extremely easily, apply to; of dredge of mud of Suzhou river bottom to undertake to groovy grab bucket environmental protection is transformed hard, the influence of earth of hourglass of leakage of the grab bucket in reducing dredge process significantly to water system water quality, be worth promotion application.
中试表明，液压反铲挖泥船、抓斗反铲挖泥船施工效率较高，抓斗式挖泥船疏浚比反铲式挖泥船对水环境影响程度小；绞吸式挖泥船，由于底泥富含杂物，吸口极易堵塞，难以适用于苏州河底泥疏浚；对常规抓斗进行环保改造，显著减少疏浚过程中抓斗漏水漏土对水体水质的影响，值得推广应用。
It introduces the renovation method for cutter suction dredger by add ing hydraulic arm－ type mud pump＆ suction device as main part of mud suction＆ water jetting device, through which the original cutter suction dredger is renovated into a compatible dredging workboat with the functions of both cutter suction and pumping.
介绍加装液压机臂式吹吸装置作为吸泥、冲水装置主体的改造办法，将原绞吸式挖泥船改造成集绞吸和吹泥一体的兼容型疏浚工程船。
Nanjing Changjiang Waterway Engineering Bureau currently has the Netherlands, Japan and China to build its own large and medium-sized aircraft from harrow suction, suction, chain bucket, grab dredger, blowing mud vessels and other vessels dredging ships, as well as a large number for the dredging, fill supporting the use of auxiliary vessels and ancillary equipment such as sludge pipeline.
长江南京航道工程局目前拥有荷兰、日本和我国自行建造的大、中型自航耙吸式、绞吸式、链斗式、抓斗式挖泥船、吹泥船等多艘疏浚工程船舶，以及大批为疏浚、吹填配套使用的辅助船舶和排泥管线等辅助设备。

Mud pool scratching for ZG-45 drive-scratching surrounding Mud Center Drive arms and Scraper dredger.
二池刮泥机为ZG—45型周边传动刮泥机和中心传动双臂式刮吸泥机。
According to these data, subsidence of dredger fill-grout in standing water can be divided into two stages: fine-particle flocculation stage and mud self-weight consolidation stage, which laid foundation for further study on characteristics of sedimentation of dredger fill.
由此得出吹填泥浆在静水中的沉降过程可以划分为两个阶段，即细颗粒絮凝下沉为主的沉积阶段和泥浆自重固结阶段，为进一步研究吹填土的沉积特性奠定了基础。
The dredger spooned up mud.
