[0002] Deep-hole grouting refers to injecting slurry into ground cracks to complete the repair work.
[0003] However, when grouting currently, generally, the pressure grouting method is used, and artificial control is carried out to prevent the slurry from returning, that is, the so-called "only in and no out". As the grouting time continues, after a long time of perfusion, the slurry absorption gradually decreases, and the slurry flow rate in the grouting section gradually decreases. At this time, the cement particles in the slurry are prone to precipitate, which may block the crack opening. Content of the Utility Model
[0004] The purpose of the utility model is to provide a high-pressure deep-hole penetration circulation grouting system to solve the problem that when grouting and repairing cracks, the precipitation of cement particles in the slurry causes blockage of the crack opening.

DETAILED DESCRIPTION OF THE EMBODIMENTS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0023] The following will Figures 1 to 4 describe the present utility model in detail.
[0024] A high-pressure deep-hole infiltration circulating grouting system includes a mixer 1. One side of the mixer 1 is connected to a flow sensor 2. One side of the flow sensor 2 is connected to a grouting pump 3. One side of the flow sensor 2 is connected to a pipeline 6. One side of the pipeline 6 is connected to a return slurry pipe 7. One side of the return slurry pipe 7 is connected to a storage barrel 8. One side of the storage barrel 8 is provided with a discharge port 801. In the middle of the discharge port 801, there is a filter screen 8011. In the middle of the discharge port 801, there is a cleaning component. The cleaning component slides around the side wall of the discharge port 801. The mixer 1 also includes a density sensor 4 and a recorder 5. The density sensor 4 is arranged on the pipeline connecting the mixer 1 and the grouting pump 3. The recorder 5 is connected to one side of the density sensor 4. The flow sensor 2 and the density sensor 4 are electrically connected to the recorder 5 through wires. The return slurry pipe 7 is connected to the mixer 1 through a pipeline.
[0025] First, the mixer 1 stirs and heats the slurry. Then, the grouting pump 3 pumps and conveys the slurry into the pipeline 6 and injects it into the gap to grout and infiltrate the gap, so as to fill and fix the gap. At the same time, during the conveying process, the flow sensor 2 is used to monitor the conveying volume, and the density sensor 4 is used to detect the consistency of the slurry. Then, the data is transmitted to the recorder 5 through wires for conversion and display, so as to better observe and control the conveyed slurry.
[0026] Then, after the slurry is conveyed, the excess slurry is pumped and recovered through the return slurry pipe 7 and conveyed to the storage barrel 8. Then, through the filter screen 8011 in the discharge port 801 of the storage barrel 8, the recovered slurry is filtered and then conveyed back to the mixer 1 for stirring, so as to keep the slurry in a flowing state all the time and prevent the cement particles in the slurry from precipitating due to standing, resulting in the blockage of the gap.
[0027] Further, the cleaning component includes a delivery pipe 8012, a fitting opening 8013, a connecting block 802, and a surrounding slider 8021. The delivery pipe 8012 is disposed on the sidewall of the discharge port 801. The fitting opening 8013 is provided at the top of the delivery pipe 8012. The connecting block 802 is arranged on the sidewall of the delivery pipe 8012. The surrounding slider 8021 is disposed on both sides of the connecting block 802. The delivery pipe 8012 is a pipe with a semi-cylindrical shape for a part of the sidewall of the discharge port 801. The connecting block 802 is a semi-cylinder connected to the fitting opening 8013 through the surrounding sliders 8021 on both sides. The connecting block 802 and the delivery pipe 8012 cooperate to form a cylinder.
[0028] Meanwhile, when filtering and recycling the slurry through the filter screen 8011, the filtered sand and stone impurities will be blocked into the discharge port 801. When a certain amount accumulates, by controlling the connecting block 802 to apply force, it rotates along the chutes on both sides of the middle of the fitting opening 8013 through the surrounding sliders 8021 on both sides, so that the connecting block 802 will overlap on the top of the delivery pipe 8012, and the hollow part at the bottom of the delivery pipe 8012 will be exposed. Since the connecting block 802 replaces the bottom of the entire discharge port 801, the filtered sand and stone impurities will accumulate on the inner wall surface of the connecting block 802. After the connecting block 802 rotates and overlaps on the top of the delivery pipe 801, the accumulated sand and stone impurities will directly fall out through the hollow part at the bottom of the delivery pipe 8012, thus completing the cleaning of the discharge port 801, preventing the sand and stone impurities from accumulating together and affecting the filter screen, and also avoiding the problem that it is inconvenient to clean the internal filter screen of the discharge port 801.
[0029] The following is the specific implementation process of the present invention. First, the slurry is stirred and heated by the mixer 1, and then the slurry is pumped and conveyed into the pipeline 6 through the extraction of the grouting pump 3 and injected into the gap to grout and infiltrate the gap, so as to fill and fix the gap. At the same time, during the conveying process, the flow sensor 2 is used to monitor the conveying amount, and the density sensor 4 is used to detect the consistency of the slurry. Then, the data is transmitted to the recorder 5 through the wire for conversion and display, so as to better observe and control the conveyed slurry. After the slurry is conveyed, the excess slurry is pumped and recycled through the return pipe 7 and conveyed to the storage barrel 8. Then, the slurry is filtered through the filter screen 8011 in the discharge port 801 of the storage barrel 8 and then conveyed back to the mixer 1 for stirring, so as to keep the slurry in a flowing state all the time, preventing the cement particles in the slurry from precipitating due to standing and causing blockage of the gap.
[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
