Automatic resetting device and method for controlling construction settlement deformation of underground pipeline
The invention discloses an automatic reset device and method for controlling construction settlement deformation of an underground pipeline, and the installation of the reset device is realized before the construction is started. In the initial stage, pipeline positioning and deformation control device installation are achieved, and a set of multi-point settlement control system is formed. In the construction process, when settlement deformation of the pipeline is monitored, the reset device exerts the axial force in real time, the settlement deformation of the pipeline is counteracted in real time, dynamic and accurate control over the settlement deformation of the pipeline is achieved, and therefore accumulation of deformation can be avoided. After construction is finished, grouting can be carried out through a grouting hole designed in the reset device, gaps possibly appearing at the bottom of the pipeline are filled, and the stability of the pipeline after the device is unloaded and dismantled is guaranteed. According to the device, real-time control over the whole process of settlement deformation is achieved, the accumulative effect of deformation is avoided, counter force is applied from the initial stage, development of deformation is controlled, and settlement deformation is controlled in real time along with the proceeding of the construction process.
本发明公开了一种控制地下管线施工沉降变形的自动化复位装置及方法，在施工开始前，实现复位装置的安装。在初始阶段，实现管线的定位及变形控制装置的安装，形成一套多点位的沉降控制体系。在施工过程中，当监测到管线发生沉降变形时，复位装置将实时进行轴力施加，实时抵消管线的沉降变形，实现管线沉降变形的动态精准控制，从而可以避免变形的累加。施工结束后，可以通过复位装置设计的灌浆孔，进行注浆，填充管线底部可能出现的空隙，保证管线在装置卸荷、拆除后的稳定。本装置实现了沉降变形的全过程实时控制，避免了变形的累加效应，从初始阶段就开始施加反力，控制变形的发展，随着施工过程的进行，实时控制沉降变形。
