冠诚清淤机械:
随着经济日新月异的快速发展,市场竞争日趋激烈,我公司的清淤设备质量和性能都大幅度提升,下面介绍一下清淤设备的正确操作方法:
1.开挖方向的确定:为分析水流方向对挖泥船施工效率的影响,施工过程中分别对顺、逆流开挖进行试验,实验结果表明,采用顺流开挖挖泥船效率较低,含沙量约为7%—10%(体积比,下同),而逆流开挖效率较高,含沙量达10%~12%,最高达17%。并且在顺流开挖时,由于水流压力,水上输泥管线易打弯,施工受到一定影响;在逆流开挖时,管线畅通。
2.边坡开挖:设计开挖边坡1:5,清淤设备根据疏浚施工技术规范,采用下超上欠的阶梯开挖法,自然塌落形成边坡,坡比接近1:4~1:6之间。
Guancheng dredging machinery:
With the rapid development of economic change rapidly, the market competition is increasingly fierce, dredgingequipment quality and performance of our company are greatly improved, the following introduces the properoperation method about dredging equipment:
The 1 excavation of determining the direction: effects on dredger construction efficiency analysis of the flow direction,the construction process of excavation, respectively along the counter current test, the experimental results show that, using the downstream excavation dredging efficiency is low, the sediment concentration is about 7% - 10%(volume ratio, the same below), and the countercurrent excavation efficiency is high, the sediment concentrationamounts to 10%~12%, up to 17%. And in the downstream excavation, due to water pressure, water mud conveyingpipeline is easy to bend, construction affected; in countercurrent excavation, pipeline unimpeded.
2: Design of slope excavation of slope excavation 1:5, dredging equipment according to the technical specification ofdredging construction, using ladder super owed on the excavation method, the natural cave formation slope, slope ratio close to 1:4~1:6 between.
