Problems solved by technology
[0003] At present, the existing detection methods mainly use ground-penetrating radar equipment to detect the full cross-section and longitudinal detection of the grouting body behind the shield tunnel wall. Since the detection device does not extend into the grouting body, its detection effect and accuracy are poor

A shield tunnel hoisting hole broken wall extension type electromagnetic wave ground detection system, the system is composed of an extension type electromagnetic wave transmitting probe rod, an extension type electromagnetic wave receiving probe rod and a borehole geological radar. The probe rod and the extended electromagnetic wave receiving probe rod are respectively connected with the transmitting antenna and the receiving antenna of the borehole geological radar. Its application is to perform tomographic scanning on the back grouting body of the shield tunnel wall through the borehole geological radar, and then obtain the distribution range of the back grouting body of the shield tunnel wall through data analysis and inversion calculation; combined with the on-site construction parameters and the grout Performance, feedback and adjust the grouting volume and grouting pressure of each subsequent grouting pipe to ensure the construction quality of the tunnel. The invention can well detect the synchronous grouting effect of the shield tunnel in different formations, so as to feed back the grouting amount and grouting pressure of the on-site synchronous grouting, so that the synchronous grouting control method of the shield tunnel is more scientific.
Description
technical field [0001] The invention belongs to the field of tunnel and underground engineering, and relates to a device suitable for evaluating the synchronous grouting effect of a shield tunnel and feedback to determine the on-site grouting amount and grouting pressure, in particular to a shield tunnel hoisting hole broken wall extension type electromagnetic wave ground detection system . Background technique [0002] During shield construction, there is a certain gap between the segment and the ground. In order to prevent the deformation of the ground, improve the impermeability of the tunnel, and ensure the early stability of the segment lining (uniform external force), it is necessary to adopt a reasonable grouting amount and grouting pressure. Perform synchronous grouting. At present, the determination of the grouting amount is based on the gap between the tail of the shield and considering the appropriate fullness coefficient in combination with the formation, route ...
