山东省的鲁北地区属第四纪河流冲积层,多为砂性土。滨海地区有沼泽、淤泥、草根等,地下水位高并受海水顶托,地基软而含水丰富。在这里进行施工,搞好施工排水至关重要。经过不断的探索,由于运用了多种软基排水技术,使这一地区先后修建了上万座大中小型闸涵桥工程。这里介绍六种软基排水技术: 一、明沟排水(即表面排水)法。适用于粘土、砂壤土、粘砂相间的杂土层的施工排水,尤其适合当前
Lubei area in Shandong Province is a Quaternary river alluvium, mostly sandy soil. Coastal areas have swamps, silt, grass roots, high groundwater level and by the seawater support, the foundation soft and rich in water. Construction here, do a good job of construction drainage is crucial. After continuous exploration, due to the use of a variety of soft-based drainage technology, so that the region has built tens of thousands of small and medium sized gate culvert bridge project. Here are six soft-based drainage technology: First, the ditch drainage (surface drainage) method. Suitable for construction drainage of clay, sand loam, sand and clay mixed layer, especially for the current
