Grout pipes placed within a fill could be damaged by the fill as it is being placed over the pipe, the pipe needs protection until it is used. In addition, the grouting pipes needs multiple outlets to ensure that the grout flows through the voids in the fill. This patent provides a method similar burrito drainage system where filter cloth is wrapped around a drainpipe encased in gravel. This patent provides a similar design but for the opposite purpose. Where fill is placed loose and grouted after placement is complete the grout tube placed within the fill needs protection until the grouting is complete. This is done by surrounding the grout tube with granular material that will carry the load of the fill above around the pipe to ensure the integrity of the pipe and allow grout to flow out through numerous voids in the granular material.

The present invention provides an intelligent construction control method, apparatus, and system for splitting jet grouting mixing piles, relating to geotechnical engineering. The method includes receiving real-time perception information from a construction information self-perception system, which includes drilling depth, drilling rig output power, drill bit torque, drill rod axial force, and pore water pressure of the drill bit. This information is input into a trained machine-learning model for stratum information, establishing a nonlinear implicit correspondence relationship between the perception information and construction stratum conditions, and outputting real-time stratum state information. The real-time stratum state information is then input into a trained self-matching machine-learning model for optimal construction parameters, establishing a nonlinear implicit correspondence relationship between the stratum state information and optimal construction parameters, and outputting current optimal construction parameters. This invention enables real-time intelligent inversion of stratum information and dynamic self-optimization control of construction parameters.

Jet grouting involves injecting grout into geological material to improve its quality; however, use of jet grouting is limited to situations in which the injection systems can be positioned relatively close to the region to be improved. This can be impractical (for example in heavily built up areas, rough terrain or beneath the seabed) or inconvenient (for example where closing a tunnel would be required). The present invention enables deployment equipment 41 to be passed down a bore in order to deploy material and/or equipment through a hole in the lining of a bore 43 into the underlying geology. In this way, underground assets may be repaired from a location external to the asset, allowing repair in situations where it would be impossible or cost-prohibitive to do so with conventional ground treatment techniques.
