【摘要】：滨州港3万吨级航道工程土质具有颗粒细、密实、极硬等特点,绞吸船施工该土质时,存在绞刀电机电流波动幅度大、正刀施工容易跑刀、横移锚容易走锚、生产率较低等问题。为有效解决上述问题,通过对比分析绞吸船不同绞刀形式、调整挖掘进尺、优化施工关键参数、查找排泥管线额外阻力等方法,使绞吸船绞刀电机电流波动幅度下降,改善了正刀施工容易跑刀现象,横移锚不再走锚,生产率提高了约15%,节约施工成本的同时也缩短了工期。
[Abstract]:The soil quality of the 30,000 ton waterway project of Binzhou Port has the characteristics of fine grain, dense density, extremely hard and so on. In the construction of the soil by winch suction, there is a large fluctuation in the current of the winch motor, easy to run the knife in the construction of the positive knife, and easy to move the anchor to anchor when moving the anchor horizontally. Low productivity and other problems. In order to solve the above problems effectively, by comparing and analyzing the different forms of winch, adjusting the excavation advance, optimizing the key parameters of construction and finding out the extra resistance of the draining pipe, the current fluctuation amplitude of the winch motor of the winch is reduced. The phenomenon of easy to run the knife in the construction of the main knife is improved, the anchor is removed from the anchor, the productivity is increased by about 15%, and the construction cost is saved and the construction period is shortened at the same time.
