Cutter suction dredger excavation method for arc-shaped grooving
The invention provides a cutter suction dredger excavation method for arc-shaped grooving, which is characterized by comprising the following specific steps of: 1, acquiring excavation data of the size of a cutter suction dredger body, left and right side lines of the grooving and an axis, and establishing a mathematical model according to the excavation data, and 2, acquiring the relative footage difference of the left and right side lines in a single trolley stroke of the cutter suction dredger, and determining the arc-shaped grooving according to the relative footage difference. Step 3, calculating a tangent point coordinate and a tangent equation of a channel axis; step 4, obtaining a construction auxiliary guide diagram of the arc-shaped groove of the cutter suction dredger, and keeping that a steel pile of the cutter suction dredger is located on a tangent line all the time for transverse excavation; the method can reduce ship moving times under the condition of ensuring that left and right half-range excavation volumes of the groove are close, ensures that left and right side feed amounts of arc excavation are close, is stable and efficient in excavation productivity, improves the productivity of the cutter suction dredger, reduces plane construction errors, and is suitable for the cutter suction dredger to excavate various arc-shaped grooves.
本发明提供一种弧状挖槽的绞吸船开挖方法，其特征在于具体步骤为步骤一获取绞吸船船体尺度、挖槽左右边线以及轴线的开挖数据，并以此建立数学模型，步骤二获取绞吸船单个台车行程内左右边线相对进尺差，并以此数据为判别指标，步骤三计算航道轴线切点坐标和切线方程，步骤四获取绞吸船弧状挖槽的施工辅助导行图并保持绞吸船钢桩始终坐落在切线上进行横移挖掘；本发明可在保证挖槽左右半幅挖掘方量相近的情况下减少移船次数，保证挖弧左右侧进刀量相近、挖掘生产率平稳高效，提高绞吸船产能，减少平面施工误差，该方法可适用于绞吸船开挖各类弧形挖槽。
