Foundation trench excavation construction method based on cutter suction dredger
The invention relates to a foundation trench excavation construction method based on a cutter suction dredger. Comprising the following steps that S1, the section of a foundation trench is partitioned into an in-trench main body region, an in-trench quality layer region and side slope quality layer regions, the in-trench quality layer region is located below the in-trench main body region, and the side slope quality layer regions are located on the two sides of the in-trench main body region; s2, excavation construction is conducted on the in-groove main body area in a layered step mode, and layered step type excavation is conducted after the layered excavation construction thickness is planned; and S3, synchronous excavation construction is conducted on the in-groove quality layer area and the slope quality layer area, it is guaranteed that the lowering depth of a reamer is constant when the in-groove quality layer area is excavated, it is guaranteed that the transverse moving speed of the reamer is constant when the slope quality layer area is excavated, and in the step, the speed of a rising and falling bridge is calculated, set and controlled; and the lifting action of the cutter-suction ship bridge frame is matched with the transverse movement action of the reamer. According to the construction method, the construction quality of foundation trench excavation is improved, and the construction efficiency is improved.
本发明涉及一种基于绞吸船的基槽开挖施工方法。包括以下步骤，步骤S1、对基槽的断面进行分区，分为槽内主体区、槽内质量层区和边坡质量层区，槽内质量层区位于槽内主体区的下方，边坡质量层区位于槽内主体区的两侧；步骤S2、对槽内主体区采用分层台阶方式进行开挖施工，规划分层开挖施工厚度后逐层阶梯式开挖；步骤S3、对槽内质量层区和边坡质量层区进行同步开挖施工，开挖槽内质量层区时，保证绞刀下放深度恒定，开挖边坡质量层区时，保证绞刀横移速度恒定，在本步骤中，计算设定和控制起落桥速度，保证绞吸船桥架起放动作同绞刀横移动作相匹配。本发明的施工方法提升了基槽开挖的施工质量并且提升了施工效率。
