Research On Key Technology Of Construction Of Underground Comprehensive Pipe Gallery Of Lanshi CBD

With the acceleration of urbanization,the development of underground space has ushered in a peak period.The improvement of the development level of the city in the new era and the acceleration of the pace of construction have put forward higher requirements for the effective setting of its infrastructure.As an emerging structural facility,the underground integrated pipe corridor has gradually entered the people's field of vision.The development and utilization of this has become an important part of urban construction.Many cities have begun to build integrated pipe corridors.Different terrains and construction conditions have made the construction of pipe corridors more complicated and the construction difficulty has increased.Therefore,the requirements for key construction technologies are becoming more and more strict,and it is necessary to attach importance to it.Under the premise of ensuring the quality of construction,we should maximize the economic and ecological benefits.The urban integrated pipe corridor is an important part of the urban infrastructure.It can improve the city's traffic and improve the overall quality of the city's disaster prevention and resilience.It effectively solves the maintenance and expansion of various pipelines in the urban development process.The problems caused by the "pull link" and the aerial "spider web" have greatly improved the image of the city and have promoted the creation of a harmonious urban ecological environment.Taking lanshi CBD project as an example,this paper studies and analyzes the integration node of comprehensive pipe corridor and other projects.From the perspective of overall design,focus on some key points in the design process to conduct research and discussion.The project construction creatively proposed and adopted the "integrated" construction mode.Firstly,the Lanshi CBD underground integrated pipe gallery was introduced,and the specific construction technical points were explored in detail.The key technology was excavated from the foundation pit and the earthwork was excavated.The real-time monitoring report,the main reflection casting construction of the pipe gallery,the prefabricated construction technology of the pipe gallery,the waterproof engineering and the deformation joint construction research have improved the construction efficiency and prolonged the service life of each pipeline,so as to provide reference for other projects.
