Research on the Application Technology of Composite Ribbed Plastic Formwork in Underground Integrated Pipe Corridor
Formwork is an important tool in the construction of underground integrated pipe corridor,and the ap-plication of formwork is directly related to the construction quality of the whole pipe corridor,therefore,a new construction technology is proposed to apply the composite ribbed plastic formwork to the underground integrated pipe corrider.According to the actual situation of the underground integrated pipe corridor,the composite ribbed plastic formwork is designed,processed,and transported to the construction site for installation,concrete is poured in the composite ribbed plastic formwork,and the support system is set up.After streng thening the composite ribbed plastic formwork,once the concrete in the composite ribbed plastic formwork reaches the design strength,the composite ribbed plastic formwork and the supporting system are removed,so as to complete the construction of the underground integrated pipe corridor based on the composite ribbed plastic formwork.The results of exam-ple analysis show that the design technology makes the deformation of concrete structures at different measuring points lower than the maximum allowable limit,which meets the requirements of relevant specifications,and all construction sections are completed within the expected construction period,which proves that the design tech-nology has a good construction effect and has a good application prospect in the field of underground integrated pipe corridor.
