The invention relates to a width-limiting bridge crossing method for a non-self-propelled cutter suction dredger. Comprising the following steps that S1, the stern of the cutter suction dredger is adjusted to face a channel, and when the vertical distance between the center of three cable columns of the stern and an inlet of the channel is d1, the cutter suction dredger stops moving and keeps the position; s2, under the assistance of the auxiliary ship, the two grab ships slowly get close to the channel inlet and the channel outlet correspondingly, the directions of the grab ships are adjusted, and when the distance between the stern of the cutter suction dredger and the side of the channel outlet side grab ship is L1 and the distance between the cutter suction dredger reamer and the side of the channel inlet side grab ship is L2, the lower steel piles of the two grab ships are positioned, and the channel inlet side grab ship is located; the grab dredger tightens the four positioning anchor cables; s3, a near-side anchor cable winch of the grab dredger on the channel outlet side takes up the cable, a near-side anchor cable winch of the grab dredger on the channel inlet side releases the cable synchronously, and when the distance between the stern of the cutter suction dredger and the ship side of the grab dredger on the channel outlet side is L2, the two grab dredgers stop taking up and releasing the cable; s4, the steel piles are lifted by the two grab ships, when the distance between the stern of the cutter suction dredger and the rail of the grab ship on the channel outlet side is L1, the grab ship stops moving, the grab ship on the channel inlet side slowly gets close to the cutter suction dredger, when the distance between a reamer of the cutter suction dredger and the rail of the grab ship on the channel inlet side is L2, the grab ship stops moving, and the lower steel piles of the grab ship on the channel inlet side are positioned; and S5, repeating the steps S3 and S4. The invention provides a non-self-propelled cutter suction dredger width-limiting bridge crossing method. The feasibility and safety of operation of a suction dredger in a width-limiting bridge crossing scene are improved.

    本发明涉及一种非自航绞吸船限宽过桥方法。包括以下步骤:步骤S1,调整绞吸船的船艉朝向通道,当船艉的三缆柱中心至通道入口的垂向距离为d1时,绞吸船停止移船并且保持船位;步骤S2,在辅助船舶的辅助下,两艘抓斗船分别缓慢靠近通道入口和通道出口,调整抓斗船的方向,并使得绞吸船船艉与通道出口侧抓斗船船舷的间距为L1时,绞吸船绞刀与通道入口侧抓斗船船舷的间距为L2时,两艘抓斗船下钢桩定位,抓斗船收紧四个定位锚缆;步骤S3,通道出口侧抓斗船近侧锚缆绞车收缆,通道入口侧抓斗船近侧锚缆绞车同步放缆,当绞吸船船艉与通道出口侧抓斗船船舷的距离为L2时,两艘抓斗船停止收放缆;步骤S4,两艘抓斗船起升钢桩,当绞吸船船艉与通道出口侧抓斗船船舷的间距为L1时抓斗船停止移船,通道入口侧抓斗船缓慢靠近绞吸船,当绞吸船绞刀与通道入口侧抓斗船船舷的间距为L2时抓斗船停止移船,通道入口侧抓斗船下钢桩定位;步骤S5,重复步骤S3和S4。本发明提供了一种非自航绞吸船限宽过桥方法,提升吸船在限宽过桥场景中操作的可行性以及安全性。
