The device is further provided with a plurality of lengthened pipes, the lengthened pipes are in threaded connection with the guide pipe, and the two adjacent lengthened pipes are also in threaded connection. The lengthening pipe and the guide pipe can be completely the same, namely, the lengthening pipe and the guide pipe are hollow metal pipes, the length and the size can be the same, the lengthening pipe and the guide pipe can also be divided into different specification lengths, two adjacent pipes are lengthened through threaded connection, and the lengthening pipe and the guide pipe are more convenient to be suitable for construction operation of drilling holes with different depths.
In the construction process, the environment inside the soil body is visually detected in real time through a preset drill hole, so that the leakage channel can be accurately secondarily positioned; the temperature sensing probe and the pressure sensing sheet can monitor the temperature and pressure change conditions in the reaction process of the high polymer slurry in real time, and accurately master the leakage treatment process; after grouting, the plastic shell is stained with semi-cured high polymer slurry or completely fixed in the cured high polymer, at the moment, the grouting pipe is pulled to connect with the drawing wire of the buckle, the grouting pipe and the buckle fall off (high-pressure gas is introduced into the grouting pipe to completely discharge the high polymer slurry), then the cleaning liquid guide pipe is pulled, and the cleaning liquid guide pipe and the top end of the disposable backflow prevention device fall off at the sleeving position. The temperature sensing probe and the pressure sensing sheet are pulled to lead the wires of the temperature sensing probe and the pressure sensing sheet to fall off, thus realizing repeated application of main equipment except disposable articles.
While the preferred embodiments for carrying out the invention have been described in detail, it should be understood that they have been presented by way of example only, and not limitation as to the scope, applicability, or configuration of the invention in any way. The scope of the invention is defined by the appended claims and equivalents thereof. Many modifications may be made to the foregoing embodiments by those skilled in the art, which modifications are within the scope of the present invention.
