Pipeline in-situ protection automation device relating to foundation pit excavation and installation method
The invention discloses a pipeline in-situ protection automation device related to foundation pit excavation and an installation method. The installation method comprises the steps that S1, a combined steel beam and a motor device are installed above a top beam; s2, intelligent monitoring points are arranged on the pipe gallery, and initial values are collected; s3, after the foundation pit has the excavation condition, the pipeline position is exposed, a groove is manually formed in the bearing installation position below the pipe gallery, and a bearing is installed; s4, penetrating a steel strand rope to connect the bearing and the motor device; s5, earthwork is excavated between the two supports, and a jump excavation mode is adopted; s6, remaining earthwork below the pipe gallery is excavated out; and S7, subsequent foundation pit excavation and structure back-building construction are started, earthwork is excavated downwards, and the device dynamically adjusts and protects the pipe gallery structure to be in a healthy state. According to the system, each motor device is dynamically controlled to automatically tighten or loosen the steel twisted rope, the pipe gallery is dynamically adjusted to be located at the target position, the problems of structural deformation, cracking, damage and the like caused by differential settlement due to the influence of external construction are avoided, and the effect of protecting the pipeline is achieved.
本发明公开一种涉及基坑开挖的管线原位保护自动化装置及安装方法，包括S1，在冠梁上方安装组合钢梁及电动机装置；S2，在管廊上布置智能监测点，采集初始值；S3，基坑具备开挖条件后，暴露出管线位置，在管廊下方承托安装位置人工掏出凹槽，安装承托；S4，穿钢绞绳连接承托和电动机装置；S5，在两承托之间开挖土方，采用跳挖方式；S6，挖除管廊下方剩余土方；S7，开始后续基坑开挖及结构回筑施工，向下开挖土方，装置动态调节保护管廊结构处于健康状态。本发明系统动态控制每组电动机装置自动收紧或放松钢绞绳，动态调整保证管廊处于目标位置，避免因外界施工影响产生不均匀沉降而发生结构变形、开裂以及破坏等问题，起到了保护管线的作用。
