Method for preventing pipe gallery concrete from cracking
The invention relates to a method for preventing cracking of pipe gallery concrete, which comprises the following steps of: after acquiring an ultimate tensile strain value of the pipe gallery concrete at each age, arranging a plurality of monitoring points on an end position cross section, a common position cross section and a middle position cross section of a pipe gallery structure; temperature data and deformation data of pipe gallery concrete are dynamically monitored through implementation of a sensor of each monitoring point, dynamic adjustment is conducted in real time according to on-site monitoring data, and particularly when the temperature data and strain data measured on site are close to control indexes, cracking early warning prompt is conducted. And workers can take preventive measures to prevent the pipe gallery concrete from cracking. Through real-time monitoring data, cracking of pipe gallery concrete can be predicted in advance, then measures can be taken in advance to avoid the situation, structure leakage can be effectively controlled, and the problem of cracks of side walls and bottom plates of key parts of a cast-in-place buried section tunnel is solved.
本发明涉及一种防止管廊混凝土开裂的方法，获取管廊混凝土每天龄期的极限抗拉应变值后，在在管廊结构的端头位置截面、普通位置截面和中间位置截面上布设多个监测点，通过每个监测点的传感器的实施动态监测管廊混凝土的温度数据和变形数据，根据现场监控数据实时进行动态调整，尤其是在现场所测到的温度数据和应变数据接近控制指标时，进行开裂预警提示，以使工作人员采取预防措施来预防所述管廊混凝土开裂。通过实时监测数据，可以提前预知管廊混凝土开裂，进而能够进行提前采取措施来避免上述情况的发生，能够有效控制结构渗漏，解决现浇暗埋段隧道关键部位侧墙和底板的裂缝问题。
