Abstract

The embodiment of the invention provides an information tracking grouting method, comprising the following steps of: detecting stratum information through a probe hole arranged on the stratum, and dividing the stratum into a strong water area and a weak water area according to the stratum information; carrying out basic grouting in the weak area; carrying out reinforced grouting in the strong water area; and checking the grouting effect. In the information tracking grouting method of the embodiment of the invention, the stratum information can be detected through the probe hole arranged on the stratum to determine the stratum information, and grouting and water plugging are carried out with pertinence according to the stratum information, thereby the grouting and water plugging as well as the strengthening effect are ensured, the amount of grouting wells is reduced, and the grouting efficiency is remarkably improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of tunnels and underground engineering, in particular to an information tracking grouting method. Background technique [0002] Prior Art In tunnel excavation and other projects, when a fault composed of structural breccia, fractured rock, and fault gouge is encountered, the fault is weak, broken, and rich in groundwater because it is often loosely cemented, the rock mass is broken, and it is rich in groundwater. For water formations, grouting and water blocking reinforcement are required before subsequent works can be carried out. The commonly used method can be full-section curtain grouting technology. This technology regards the formation as a uniform body, and performs full-scale grouting and water blocking reinforcement according to uniform grouting parameters. [0003] In the process of realizing the present invention, the inventor found that there are at least the following...
