在邻近建筑物、软土地基建造人防通道、工艺管沟、防洪沟、电缆沟等,施工时会遇到很大困难,由于管沟要大开挖,易引起滑坡坍方,影响邻近建筑物的安全。采用预制的沉管式的施工方案,就可以解决上述情况下的施工问题。沉管式通行电缆沟是某港在软土地基条件下设计的一个新方案。工程具有管线长、管径窄、支撑密、防水严、土质不稳定的特点。沉管全长775米,分33节,每节分别长18、21、24米三种。在每两节沉管中
In the construction of nearby buildings and soft ground, civil air defense channels, process trenches, flood control trenches, cable trenches, etc., will encounter great difficulties in construction. Due to the large excavation of the trench, it is easy to cause landslides and affect the neighboring buildings. Safety. The use of prefabricated immersed tube construction solutions can solve the construction problems in the above situations. The immersed tube type cable channel is a new scheme designed by a port under the conditions of soft soil. The project has the characteristics of long pipeline, narrow diameter, dense support, strict waterproofness, and unstable soil quality. The immersion tube has a total length of 775 meters and is divided into 33 sections. Each section is 18, 21, and 24 meters long. In every two immersed tubes
