Construction method for excavating complex soil by cutter suction dredger
The invention discloses a construction method for excavating complex soil through a cutter suction dredger. The construction method comprises the following steps that firstly, geological exploration is conducted on a construction area to be excavated; 2, a cutter suction dredger is in place, sludge on the geological surface layer is excavated, and a sludge bottom layer which is 1-2 m thick away from the interface of the sludge and clay is reserved and not excavated; 3, a clay layer surface layer is excavated, and excavation is conducted in the mode that a 1-2 m thick silt bottom layer and a 2 m thick clay surface layer are excavated in a mixed mode, wherein the silt bottom layer and the clay surface layer are reserved during silt excavation; fourthly, excavation is conducted in the mode that a clay remaining bottom layer and a medium-coarse sand surface layer with the thickness being 1-2 m are excavated in a mixed mode; and 5, excavating the medium-coarse sand, wherein the excavation depth of the medium-coarse sand is determined according to the thickness of the medium-coarse sand and the scale of the cutter suction dredger. According to the construction method, the conveying efficiency of clay in complex geology can be greatly improved, the risks of pipe blockage and pipe explosion are reduced, and the construction period is greatly shortened.
本发明公开了一种绞吸船开挖复杂土质的施工方法，包括以下步骤：步骤一，首先对拟开挖的施工区域进行地质勘探；步骤二，绞吸船就位，对地质表层的淤泥进行开挖并保留距淤泥与粘土的交界面1～2米厚的淤泥底层不挖；步骤三，开挖粘土层表层，采用淤泥开挖时保留的1～2米厚的淤泥底层与2米厚的粘土表层混合开挖的方式开挖；步骤四，采用粘土剩余底层与1～2米厚的中粗砂表层混合开挖的方式开挖；步骤五，对中粗砂进行开挖，中粗砂的开挖深度根据中粗砂的厚度及绞吸船的规模进行分层多次开挖。本发明的施工方法可以大大提高复杂地质中粘土的输送效率，减少堵管、爆管的风险，大幅缩短工期。
