Relocation and transformation method for in-situ protection of underground communication pipeline

Abstract

The invention relates to the field of civil engineering construction, in particular to an underground communication pipeline in-situ protection migration and modification method which comprises the following steps: communication pipeline position determination: the position of a communication pipeline is checked in detail in combination with a pipeline drawing, and the communication pipeline in an operation range is excavated after being explored manually; reinforcing piles are built on the periphery of the side wall, located at the two ends of the communication pipeline, of the deep foundation pit within the operation range, and then a bearing table is cast on the tops of the reinforcing piles in situ and located above the communication pipeline; a truss is placed, specifically, the truss is placed on the surface of the bearing table, and the truss is transversely arranged above the communication pipeline; a plurality of prefabricated bottom plates are placed in the length direction of the communication pipeline, the prefabricated bottom plates abut against the bottom of the communication pipeline, then the prefabricated bottom plates and the truss are connected through connecting pieces, and the communication pipeline is suspended. The problem that the communication pipeline is pulled apart due to settlement deformation in the deep foundation pit when the deep foundation pit is excavated is solved.

Description

technical field [0001] The present application relates to the field of civil engineering construction, in particular to a relocation method for in-situ protection of underground communication pipelines. Background technique [0002] Water, electricity, heating, gas pipelines and communication pipelines are mostly buried underground. With the rapid development of urban construction, underground pipelines have become more complex and changeable. The implementation of the excavation will inevitably lead to the excavation of the underground soil layer, and the protection of pipelines during the excavation is particularly important. [0003] At present, when pipelines are encountered during the construction process, the construction method of in-situ suspension protection is adopted to protect the pipelines, that is, the construction is carried out under the pipelines and on the peripheral sides of the pipelines without damaging the original pipelines. Especially when the commun...
