土压平衡盾构机的土压传感器用于实时检测泥土仓压力值,盾构机操作人员根据土压传感器反馈的数据,采取相应措施调整士仓压力,直至达到设定范围内,使土压平衡得以实现,从而使地表沉降得到有效控制。施工中若出现个别土压传感器输出数据波动较大或数据变化无常等现象,就会使土压判断更为困难。本文介绍土压传感器结构原理,并介绍1种简易的土压传感器检测装置,用以分析土压传感器是否存在故障。
Earth pressure balance shield machine earth pressure sensor for real-time detection of soil pressure, shield machine operator based on earth pressure sensor feedback data, take appropriate measures to adjust the warehouse pressure until it reaches the set range, so that earth pressure Balance can be achieved, so that surface subsidence can be effectively controlled. If there is a single individual earth pressure sensor output data during construction fluctuations or data changes such as impermanence, it will make soil pressure more difficult to judge. This paper introduces the principle of earth pressure sensor structure, and introduces a simple earth pressure sensor detection device for the analysis of earth pressure sensor is faulty.
