The Construction Scheme for Pressure Pipe Jacking Through Structures
引水隧洞因其能极大程度地缩短引水距离,减少对地面生态的影响而被广泛运用.某输水管线工程顶管施工需穿越构筑物,场地周边环境复杂,施工危险性较大.为了减少对既有工程的扰动,保证工程安全,采取了注浆加固的方法对地基加固处理,提高地基土的强度和稳定性.顶管在施工过程中严格按照施工工艺要求进行,同时针对可能遇到的漂石,采取分裂法进行处理等技术措施.经过实践结果表明采用的施工措施较好,可满足施工要求,研究为类似工程施工提供借鉴.
Water Diversion Tunnel is widely utilized due to its ability to significantly shorten the distance of water diversion and minimize the impact on ground ecology.The pipe jacking construction of a water transmission pipeline project necessitates traversing through complex structural and environment conditions,thereby posing inherent risks to the construction process.The grouting method is employed to enhance the foundation and improve the strength and stability of the soil,aiming to minimize disruption to the ongoing project while ensuring its safety.The method of grouting reinforcement is employed to enhance the foundation and improve the strength and stability of the soil,aiming to minimize disruption to the existing project while ensuring its safety.During the construction of pipe jacking,strict adherence to the requirements of construction technology is essential.and may be encountered in drift stone,the split method for treatment and other technical measures.The practical results demonstrate the effectiveness of the adopted construction measures in meeting the requirements of the project,providing valuable insights for similar engineering endeavors.
