[0002] Over time, the foundations of many existing buildings have shown signs of weakening due to prolonged use. Even more concerning, historical buildings constructed solely on natural foundations are in dire need of foundation reinforcement. However, existing foundation reinforcement methods and modifications have significant impacts on buildings, often requiring the relocation of the main structure to construct a raft foundation, and are prone to damaging the building's main structure. Summary of the Invention

[0067] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0069] Historical buildings or buildings that have existed for a long time often have foundations with low bearing capacity due to the outdated technology of their construction period. Over time, the main structure is prone to loosening, making foundation reinforcement essential. However, because of their fragile foundation structure, they are susceptible to collapse under external forces, greatly increasing the difficulty of construction.

[0070] Therefore, some embodiments of the present invention propose an intelligent grouting construction method for building raft foundations, as detailed in the accompanying drawings. Figures 1-6 As shown.

[0071] In this embodiment of the invention, the first grouting pipe 110, the second grouting pipe 120, and the grout extraction pipe 140 are all equipped with sensors 190 and multiple grouting holes 150 for spraying cutting fluid or injecting grout. Each grouting hole 150 is equipped with a valve for opening and closing the grouting hole 150. The sensors 190 are electrically connected and / or signal connected and / or connected to an MCU with the valves. The sensors 190 are used to detect physical quantity data of the surrounding soil. In this embodiment of the invention, the physical quantity data can be the pressure value of the surrounding soil detected by the sensors 190, or the values ​​of physical parameters such as density, humidity, strain, stress, composition, and weight of the surrounding soil. In this embodiment of the invention, the intelligent grouting construction method for building raft foundations can be applied to grouting equipment. The grouting power equipment is electrically connected and / or signal connected and / or MCU connected to sensor 190. The grouting power equipment includes a high-pressure pump, a third grouting pipe 130, and a geophysical device 210 located on the ground surface 200. The geophysical device 210 is electrically connected and / or signal connected and / or MCU connected to valves and the high-pressure pump, respectively. One end of the third grouting pipe 130 is connected to the high-pressure pump, and the other end is connected to the first grouting pipe 110 and / or the second grouting pipe 120 and / or the grout extraction pipe 140, respectively. The third grouting pipe 130 is used to extract sand and gravel slurry from the grout extraction area and to guide the grouting to the first grouting pipe 110 and / or the second grouting pipe 120. The geophysical device 210 is used to monitor the boundary shape change information of the first reinforced body 170 and the second reinforced body 180.

[0072] Reference Figure 1As shown in this embodiment of the invention, the intelligent grouting construction method for a building raft foundation includes:

[0073] Step 101: Insert the grouting pipe through the soil to be reinforced by 100.

[0074] Reference Figure 3 and Figure 5 As shown, it can be understood that in this embodiment of the invention, working pits can be excavated on both sides of the soil to be reinforced 100 below the existing building, and subsequent construction steps can be carried out in the working pits. In this embodiment, grouting pipes can be inserted into the soil to be reinforced 100 along the length or width direction, or along the height direction, until the grouting pipe penetrates the soil to be reinforced 100. It should be noted that there can be multiple grouting pipes, and multiple grouting pipes can be inserted into the soil to be reinforced 100 in the same direction, or they can be inserted in different directions. This embodiment does not limit this.

[0075] Step 102: Inject cutting fluid into the soil to be reinforced 100 through the grouting pipe to cut the soil to be reinforced 100 and form a grouting zone.

[0076] In this embodiment of the invention, the grouting pipe can be connected to a pressurizing device, which can pressurize the cutting fluid and inject high-pressure cutting fluid into the grouting pipe. (See reference...) Figure 3 As shown, the grouting pipe wall can be provided with grouting holes 150. High-pressure cutting fluid can be sprayed from the grouting holes 150 to cut the soil around the grouting pipe and form a cavity. Therefore, the cavity will store the sand and gravel slurry formed by cutting the soil to be reinforced 100. The cavity filled with sand and gravel slurry is the grout extraction zone. It should be noted that the grouting pipe can be inserted into the soil to be reinforced 100 along the length or width direction, or along the height direction. After cutting, a grout extraction zone can be formed along the length direction, the width direction, or the height direction of the soil to be reinforced 100, or all three types of grout extraction zones can be formed simultaneously. In this embodiment of the invention, the cutting fluid can be pressurized water or pressurized oil. Those skilled in the art can choose according to the actual situation, and this embodiment does not limit this.

[0077] In this embodiment of the invention, step 102 may include: sensor 190 and geophysical device 210 monitoring soil change data, and controlling the speed, force and range of the cutting fluid spray according to the design data.

[0078] In this embodiment of the invention, sensor 190 and geophysical device 210 can monitor soil data of the surrounding soil in real time, thereby obtaining soil change data, comparing the change data with the design data, and then controlling the speed, force, and range of the cutting fluid spray. The soil data may include soil density, moisture content, composition, and other data.

[0079] Step 103: Remove the sand and gravel slurry generated in the slurry pumping area.

[0080] In this embodiment of the invention, the grouting pipe 140 can be composed of a flexible hose and a grouting pump. Based on this, the grouting pipe 140 can remove the sand and gravel slurry generated within the grouting zone, forming a cavity. It should be noted that the various grouting zones can be interconnected. Therefore, in this embodiment, grouting can be performed using only the grouting pipe 140 inserted along the length of the soil to be reinforced 100, only the grouting pipe 140 inserted along the width of the soil to be reinforced 100, or only the grouting pipe 140 inserted along the height of the soil to be reinforced 100. Furthermore, to increase the grouting speed, grouting can be performed simultaneously using the grouting pipes 140 in the above three directions.

[0081] In this embodiment of the invention, step 103 may include: sensor 190 and geophysical device 210 monitoring physical quantity change data, and controlling pumping speed, flow rate and volume according to design data.

[0082] In this embodiment of the invention, sensor 190 and geophysical device 210 can monitor the physical quantity data of the surrounding soil in real time, thereby obtaining the physical quantity change data of the soil, and comparing the change data with the design data, thereby controlling the pumping speed, flow rate and volume. The physical quantity data may include data such as pressure values, stress values, and strain values ​​of the surrounding soil.

[0083] Step 104: Inject grout into the pumping zone through the grouting pipe to form a solidified body after solidification in the pumping zone.

[0084] Reference Figure 5As shown, in this embodiment of the invention, the grouting pipe can be connected to a high-pressure grouting device. The high-pressure grouting device can inject high-pressure grout into the grouting pipe. The high-pressure grout can flow from the grouting hole 150 provided on the pipe wall of the grouting pipe into the pumping area where the sand and gravel slurry has been removed, and fill the cavity of the pumping area. After the grout has solidified, a reinforced body can be formed. It should be noted that in this embodiment, when at least two types of grouting pipes penetrating the soil to be reinforced 100 in different directions are arranged simultaneously in the soil to be reinforced 100, pumping and grouting can be carried out simultaneously to improve efficiency. Specifically, grouting can be pumped from the grouting pipe arranged along the height direction of the soil to be reinforced 100, while grout is injected into the grouting pipe along the length direction and / or width direction of the soil to be reinforced 100. In this embodiment, when grouting and pumping are completed simultaneously, or when the amount of sand and gravel slurry that meets the design calculation is extracted, it indicates that the original soil of the soil to be reinforced 100 has been replaced with concrete. In this embodiment of the invention, quick-drying grout can be selected to increase the formation speed of the solidified body and reduce the possibility of structural loosening due to grout pumping.

[0085] In this embodiment of the invention, step 104 may include: sensor 190 and geophysical device 210 monitoring changes in soil and rock, controlling grouting speed, flow rate and volume according to design data, and controlling the size of the solidified solidified material.

[0086] In this embodiment of the invention, sensor 190 and geophysical device 210 can monitor the physical quantity data of the soil and rock in real time, thereby obtaining the change data of the physical quantity of the soil and rock, and comparing the change data with the design data, thereby controlling the grouting speed, flow rate and volume. The physical quantity data may include data such as the pressure value, stress value and strain value of the surrounding soil.

[0087] It is understood that, in this embodiment of the invention, the grouting pipe can be a high-strength steel pipe. After the solidified body is formed, the grouting pipe can be left in the soil to be reinforced 100. At this time, the grouting pipe can act as a reinforcing bar. The grouting pipe and the solidified body can form a concrete raft foundation for the building, further improving the stability of the foundation.

[0088] In this embodiment of the invention, a grouting pipe can be inserted through the soil to be reinforced 100, and cutting fluid can be injected into the soil to be reinforced 100 through the grouting pipe to cut the soil to be reinforced 100 to form a grouting zone. Then, the sand and gravel slurry generated in the grouting zone is pumped out. At the same time as grouting, grouting is injected into the grouting zone through the grouting pipe to form a reinforced body after the grouting zone solidifies. This achieves the rapid replacement of the original soil in the foundation of a building with a raft foundation with greater bearing capacity with minimal disturbance to the existing building. This includes forming a reinforced concrete raft foundation with grouting pipe reinforcement. This solves the technical problem that the existing technology cannot form an integral reinforced raft foundation or box foundation under the existing building, which significantly improves the bearing capacity of the building foundation and enhances the stability of the building foundation.

[0089] Reference Figure 2 As shown, in this embodiment of the invention, the method for reinforcing a building foundation may include:

[0090] Step 201: Insert the first grouting pipe 110 through the soil body 100 to be reinforced along the first direction.

[0091] Step 202: The second grouting pipe 120 is inserted through the soil to be reinforced 100 along the second direction, and the projection of the second direction and the first direction in the height direction intersects.

[0092] Reference Figure 5 As shown, in this embodiment of the invention, the first grouting pipe 110 can be inserted into the soil to be reinforced 100 along a first direction until it penetrates the soil to be reinforced 100. Similarly, the second grouting pipe 120 can be inserted into the soil to be reinforced 100 along a second direction until it penetrates the soil to be reinforced 100. The projections of the second direction and the first direction in the height direction intersect. For example, when the first grouting pipe 110 penetrates the soil to be reinforced 100 along its length, the second grouting pipe 120 can penetrate the soil to be reinforced 100 along its width, and vice versa. In this embodiment, the first grouting pipe 110 and the second grouting pipe 120 may not be connected. That is, the second grouting pipe 120 may be located above or below the first grouting pipe 110 in the height direction. Those skilled in the art can choose according to the actual construction environment, and this embodiment does not limit this.

[0093] Step 203: Along the length and / or height of the soil to be reinforced 100, arrange multiple first grouting pipes 110 and / or multiple second grouting pipes 120. The multiple first grouting pipes 110 are arranged at intervals at the same height, and the multiple second grouting pipes 120 are arranged at intervals at the same height.

[0094] Understandably, in order to carry out reinforcement construction on the entire 100mm of soil to be reinforced, refer to Figure 6 As shown, in this embodiment of the invention, multiple first grouting pipes 110 and multiple second grouting pipes 120 can be arranged along the length and / or height of the soil to be reinforced 100, wherein the projections of each first grouting pipe 110 and each second grouting pipe 120 in the height direction intersect. Specifically, arranging multiple first grouting pipes 110 and multiple second grouting pipes 120 along the length of the soil to be reinforced 100 ensures that multiple first grouting pipes 110 in the same layer are all at the same depth in the soil to be reinforced 100, and that the multiple first grouting pipes 110 are arranged at a certain distance from each other. Similarly, multiple second grouting pipes 120 in the same layer are all at the same depth in the soil to be reinforced 100, and that the multiple second grouting pipes 120 are arranged at a certain distance from each other, thereby achieving comprehensive coverage along the length of the soil to be reinforced 100.

[0095] Reference Figure 4 and Figure 6 As shown, in this embodiment of the invention, the first grouting pipe 110 in the same layer can be a first grouting pipe 110 at the same depth in the soil to be reinforced 100. Optionally, the first grouting pipes 110 at the same depth can be arranged at a horizontal spacing of a, wherein the horizontal spacing a can satisfy 1m ≤ a ≤ 2m. Similarly, the second grouting pipe 120 in the same layer can be a second grouting pipe 120 at the same depth in the soil to be reinforced 100. Optionally, the second grouting pipes 120 at the same depth can be arranged at a horizontal spacing of b, wherein the horizontal spacing b can satisfy 1m ≤ b ≤ 2m. It should be noted that in this embodiment of the invention, the horizontal spacing of the first grouting pipes 110 at the same depth and the horizontal spacing of the second grouting pipes 120 at the same depth can be set by those skilled in the art according to the actual situation, and this embodiment does not limit this.

[0096] In this embodiment of the invention, multiple first grouting pipes 110 and multiple second grouting pipes 120 can be arranged along the height direction of the soil to be reinforced 100, forming multiple layers of first grouting pipes 110 and multiple layers of second grouting pipes 120, so that the grouting pipes are arranged at all depths of the soil to be reinforced 100, thereby achieving comprehensive coverage along the height direction of the soil to be reinforced 100. In this embodiment, the soil to be reinforced 100 can be divided into several sub-soil layers according to the actual situation. In each sub-soil layer, at least one first grouting pipe 110 and at least one second grouting pipe 120 can be arranged so that at least one grouting zone is formed in each sub-soil layer. Specifically, the height spacing between adjacent first grouting pipes 110 and the height spacing between adjacent second grouting pipes 120 can be selected by those skilled in the art according to the actual situation, and this embodiment of the invention does not limit this.

[0097] Reference Figure 4 and Figure 6 As shown, in this embodiment of the invention, the projections of multiple first grouting pipes 110 in the height direction do not overlap, and the projections of multiple second grouting pipes 120 in the height direction do not overlap. Specifically, the projections of the first grouting pipes 110 in adjacent layers in the height direction can be spaced apart by a certain distance, and the projections of the second grouting pipes 120 in adjacent layers in the height direction can be spaced apart by a certain distance. Optionally, the horizontal interval distance of the projections of the first grouting pipes 110 in the height direction of adjacent layers can be c, satisfying 0.5m ≤ c ≤ 1m; the horizontal interval distance of the projections of the second grouting pipes 120 in the height direction of adjacent layers can be d, satisfying 0.5m ≤ d ≤ 1m. It should be noted that in this embodiment of the invention, the horizontal interval distance of the projections of the first grouting pipes 110 in the height direction of adjacent layers and the horizontal interval distance of the projections of the second grouting pipes 120 in the height direction of adjacent layers can be set by those skilled in the art according to actual conditions, and this embodiment does not limit this.

[0098] Step 204: Insert the grouting pipe 140 into the soil to be reinforced 100 along the height direction.

[0099] Reference Figure 4 As shown, in this embodiment of the invention, in the height direction, the first grouting pipe 110 and the second grouting pipe 120 of adjacent layers can be arranged to form a rectangular area, and the grout extraction pipe 140 can be inserted into the rectangular area along the height direction.

[0100] Step 205: Using the first grouting pipe 110 and / or the second grouting pipe 120, the soil to be reinforced 100 is cut to form a first grouting zone extending in the horizontal direction.

[0101] Reference Figure 3 As shown, in this embodiment of the invention, the two ends of the first grouting pipe 110 can be connected to a vertically arranged third grouting pipe 130, or the two ends of the second grouting pipe 120 can be connected to a vertically arranged third grouting pipe 130. The third grouting pipe 130 can extend upward along the side wall of the soil to be reinforced 100 and be connected to a pressurizing device. The pressurizing device can pressurize the cutting fluid and inject high-pressure cutting fluid into the first grouting pipe 110 and / or the second grouting pipe 120. The high-pressure cutting fluid can be sprayed out from the grouting holes 150 of the first grouting pipe 110 and the second grouting pipe 120 respectively, cutting the soil around the first grouting pipe 110 and the second grouting pipe 120 to form a first grouting zone extending in the horizontal direction.

[0102] Step 205 includes:

[0103] Step 2051: Detect the first current physical quantity data of the surrounding soil.

[0104] In this embodiment of the invention, the first current physical quantity data may be the pressure value of the surrounding soil detected by the sensor 190, or it may be the value of physical parameters of the surrounding soil such as density, humidity, strain, and weight. This embodiment does not limit this. Based on this, the sensor 190 may be a pressure sensor 190, a temperature and humidity sensor 190, etc., and this embodiment does not limit this.

[0105] Step 2052: Based on the first current physical quantity data and the first preset reference value, control the opening and closing amplitude and grouting direction of the valves of the first grouting pipe 110 and / or the second grouting pipe 120, and inject cutting fluid into the soil to be reinforced 100 to cut the soil to form the first grouting zone. At the same time, adjust the pumping flow rate and pumping pressure of the high-pressure pump when injecting fluid through the third grouting pipe 130.

[0106] It is understood that, in this embodiment of the invention, the first preset reference value can be the reference value corresponding to the grouting pipe valve being fully open. This embodiment can control the opening and closing degree of the valve by comparing the first current physical quantity data with the first preset reference value. Furthermore, this embodiment can also include an MCU (Microcontroller Unit) electrically connected to the sensor 190. The MCU can receive data detected by the sensor 190 and can also control the valve. In this embodiment, when a sensor 190 detects that the first current physical quantity data of the surrounding soil matches the first preset reference value, the MCU can control the valves of one or more grouting holes 150 around the sensor 190 to open or close. It is understood that when the valve is open, cutting fluid can be sprayed outwards, and when it is closed, the spraying of cutting fluid can be stopped, thus realizing the start and stop of the spraying of cutting fluid. During the spraying of cutting fluid, when a sensor 190 detects that the first current physical quantity data of the surrounding soil does not conform to a first preset reference value, the MCU can control the valves of one or more grouting holes 150 around the sensor 190 to open only to a certain extent based on the difference between the two, thereby reducing the spraying speed of the cutting fluid. Conversely, it can increase the spraying speed of the cutting fluid, thus achieving both acceleration and deceleration of the cutting fluid. It should be noted that in this embodiment of the invention, the first preset reference value can be set by those skilled in the art according to actual conditions, and this embodiment does not limit it in this way.

[0107] Step 206: Use the grouting pipe 140 to cut the soil to be reinforced 100 to form a second grouting zone 160 extending along the height direction. The second grouting zone 160 is connected to the first grouting zone.

[0108] Reference Figure 3As shown, in this embodiment of the invention, the grouting pipe 140 can be inserted into the soil body 100 to be reinforced along the height direction, that is, the grouting pipe 140 can penetrate multiple layers of sub-soil. Specifically, the grouting pipe 140 can be connected to a pressurizing device, which can pressurize the cutting fluid and inject high-pressure cutting fluid into the grouting pipe 140. The high-pressure cutting fluid can be sprayed out from the grouting hole 150 of the grouting pipe 140 to cut the surrounding soil, forming a second grouting zone 160 extending along the height direction. The second grouting zone 160 can communicate with the first grouting zone of each layer. In this embodiment, the second grouting zone 160 can be columnar or conical. Those skilled in the art can control the specific cutting form of the grouting pipe 140 according to the actual situation, and this embodiment does not limit this.

[0109] In this embodiment of the invention, step 206 includes:

[0110] Step 2061: Detect the second current physical quantity data of the surrounding soil.

[0111] In this embodiment of the invention, the second current physical quantity data may be the pressure value of the surrounding soil detected by the sensor 190, or it may be the environmental values ​​of physical parameters such as density, humidity, strain, stress, composition and weight of the surrounding soil. This embodiment does not limit this.

[0112] Step 2062: Based on the second current physical quantity data and the second preset reference value, control the opening and closing amplitude of the valve of the grouting pipe 140 and the grouting direction, and inject cutting fluid into the soil to be reinforced 100 to cut the soil to form the second grouting zone 160. At the same time, adjust the pumping flow rate and pumping pressure of the high-pressure pump when injecting fluid through the third grouting pipe 130.

[0113] It is understood that, in this embodiment of the invention, the second preset reference value can be the reference value corresponding to the fully open valve of the grouting pipe 140. This embodiment can control the opening and closing degree of the valve by comparing the second current physical quantity data and the second preset reference value. Specifically, in this embodiment, when a sensor 190 detects that the second current physical quantity data of the surrounding soil meets the second preset reference value, the MCU can control the valves of one or more grouting holes 150 around the sensor 190 to open or close. It is understood that when the valve is open, cutting fluid can be sprayed outwards, and when it is closed, the spraying of cutting fluid can be stopped, realizing the start and stop of the spraying of cutting fluid. During the spraying of cutting fluid, when a sensor 190 detects that the second current physical quantity data of the surrounding soil does not meet the second preset reference value, the MCU can control the valves of one or more grouting holes 150 around the sensor 190 to open only to a certain extent according to the difference between the two, thereby reducing the spraying speed of the cutting fluid, and conversely, increasing the spraying speed of the cutting fluid, realizing the acceleration and deceleration of the cutting fluid. It should be noted that, in this embodiment of the invention, the second preset reference value can be set by those skilled in the art according to the actual situation, and this embodiment does not limit it.

[0114] Step 207: Use the first grouting pipe 110, the second grouting pipe 120, and / or the grouting pipe 140 to remove the sand and gravel slurry generated in the grouting zone.

[0115] In this embodiment of the invention, the first grouting zone and the second grouting zone 160 can be connected. In this embodiment, the sand and gravel slurry in the first grouting zone can be pumped out through the first grouting pipe 110 and the second grouting pipe 120, while at the same time, the sand and gravel slurry in the second grouting zone 160 will also flow into the first grouting zone. This achieves the effect of the grouting pipe 140 pumping out the sand and gravel slurry in the first grouting zone and the second grouting zone 160, forming cavities extending in the horizontal direction and cavities extending in the vertical direction. Similarly, in this embodiment, the sand and gravel slurry in the second grouting zone 160 can also be pumped out through the grouting pipe 140, while at the same time, the sand and gravel slurry in the first grouting zone will also flow into the second grouting zone 160. This achieves the effect of the grouting pipe 140 pumping out the sand and gravel slurry in the first grouting zone and the second grouting zone 160, forming cavities extending in the horizontal direction and cavities extending in the vertical direction.

[0116] In this embodiment of the invention, step 207 includes:

[0117] Step 2071: Detect the third current physical quantity data of the surrounding soil.

[0118] In this embodiment of the invention, the third current physical quantity data may be the pressure value of the surrounding soil detected by the sensor 190, or the values ​​of physical parameters of the surrounding soil such as density, humidity, strain and weight. This embodiment does not limit this.

[0119] Step 2072: Based on the third current physical quantity data and the third preset reference value, control the opening and closing amplitude and grouting direction of the valves of the first grouting pipe 110, and / or the second grouting pipe 120, and / or the grouting pipe 140 and grouting to pump grout into the first grouting zone and the second grouting zone 160, and at the same time adjust the pumping flow rate and pumping pressure of the high-pressure pump when pumping grout through the third grouting pipe 130.

[0120] It is understood that, in this embodiment of the invention, the third preset reference value can be the reference value corresponding to the fully open valves of the first grouting pipe 110, the second grouting pipe 120, and / or the pumping pipe 140. This embodiment can control the opening and closing degree of the valves by comparing the third current physical quantity data with the third preset reference value. Specifically, in this embodiment, when a sensor 190 detects that the third current physical quantity data of the surrounding soil meets the third preset reference value, the MCU can control the valves of one or more grouting holes 150 around the sensor 190 to open or close. It is understood that when the valve is open, sand and gravel slurry can be extracted from the first pumping zone and the second pumping zone 160, and when it is closed, pumping can be stopped, thus realizing the start and stop of pumping. During the pumping process, when a sensor 190 detects that the third current physical quantity data of the surrounding soil does not meet the third preset reference value, the MCU can control the valves of one or more grouting holes 150 around the sensor 190 to open only to a certain extent according to the difference between the two, thereby reducing the pumping speed, and conversely, increasing the pumping speed, thus realizing the acceleration and deceleration of pumping. It should be noted that, in the embodiments of the present invention, the third preset reference value can be set by those skilled in the art according to the actual situation, and this embodiment does not limit it.

[0121] In this embodiment of the invention, step 2072 includes:

[0122] Step 20721: Detect the shape change information of the first boundary of the first grouting zone and the second grouting zone 160 during the grouting process.

[0123] It is understood that, in this embodiment of the invention, the shape and boundary conditions of the sand and gravel slurry in the first and second pumping zones 160 can be monitored in real time during pumping, thereby controlling the pumping process. Specifically, this embodiment can use a geophysical exploration device 210 to monitor the boundary shape changes of the first and second pumping zones 160, thereby obtaining the real-time boundary shape conditions of the first and second pumping zones 160. Optionally, in this embodiment, the geophysical exploration device 210 can be a geophysical radar, a geophysical probe, or other geophysical equipment. Those skilled in the art can choose to use it according to the actual situation, and this embodiment does not limit it.

[0124] Step 20722: Based on the information on the change in the shape of the first boundary, adjust the opening and closing amplitude of the valve and the grouting direction, and control the pumping flow rate and pumping pressure of the high-pressure pump when pumping grout through the third grouting pipe 130.

[0125] In this embodiment of the invention, both ends of the first grouting pipe 110 in each layer can be connected to a vertically arranged third grouting pipe 130, and both ends of the second grouting pipe 120 in each layer can be connected to a vertically arranged third grouting pipe 130. The third grouting pipe 130 can extend upward along the side wall of the soil to be reinforced 100 and be connected to a high-pressure pump. In this embodiment, the MCU can specifically control the high-pressure pump corresponding to the geophysical exploration device 210 to extract sand and gravel slurry from the first grouting zone and the second grouting zone 160 through the third grouting pipe 130 based on the first boundary shape change information. Specifically, the pumping flow rate and pumping pressure of the high-pressure pump can be specifically controlled.

[0126] Step 208: Grouting is injected into the first grouting zone and the second grouting zone 160 through the first grouting pipe 110 and the second grouting pipe 120 to form a first solidified body 170 extending in the horizontal direction and a second solidified body 180 extending in the vertical direction, so that the second solidified body 180 is connected to the multilayer first solidified body 170.

[0127] Reference Figure 6 As shown, in this embodiment of the invention, the third grouting pipe 130 can be connected to a high-pressure grouting device. While the grouting pipe 140 is pumping grout, the high-pressure grouting device can inject high-pressure grouting into the first grouting pipe 110 and the second grouting pipe 120. The high-pressure grouting can flow into the first pumping zone from the grouting holes 150 provided in the first grouting pipe 110 and the second grouting pipe 120. Since the first pumping zone and the second pumping zone 160 are connected, the grouting can also flow into the second pumping zone 160, forming a first solidified body 170 extending in the horizontal direction and a second solidified body 180 extending in the height direction, so that the second solidified body 180 is connected to the multiple layers of the first solidified body 170. The second solidified body 180 can support each layer of the first solidified body 170.

[0128] In this embodiment of the invention, step 208 includes:

[0129] Step 2081: Detect the fourth current physical quantity data of the surrounding soil.

[0130] In this embodiment of the invention, the fourth current physical quantity data may be the pressure value of the surrounding soil detected by the sensor 190, or the values ​​of physical parameters of the surrounding soil such as density, humidity, strain and weight. This embodiment does not limit this.

[0131] Step 2082: Based on the fourth current physical quantity data and the fourth preset reference value, control the opening and closing amplitude of the valve and the grouting direction, and inject grout into the first grouting zone and the second grouting zone 160. At the same time, adjust the pumping flow rate and pumping pressure of the high-pressure pump when grouting through the third grouting pipe 130.

[0132] It is understood that, in this embodiment of the invention, the fourth preset reference value can be the reference value corresponding to the full opening of the valves of the first grouting pipe 110 and the second grouting pipe 120. This embodiment can control the opening and closing degree of the valves by comparing the fourth current physical quantity data and the fourth preset reference value. Specifically, in this embodiment, when a sensor 190 detects that the fourth current physical quantity data of the surrounding soil meets the fourth preset reference value, the MCU can control the valves of one or more grouting holes 150 around the sensor 190 to open or close. It is understood that when the valve is open, grouting can be carried out in the first grouting zone and the second grouting zone 160, and when it is closed, grouting can be stopped, thus realizing the start and stop of grouting. During the grouting process, when a sensor 190 detects that the fourth current physical quantity data of the surrounding soil does not meet the fourth preset reference value, the MCU can control the valves of one or more grouting holes 150 around the sensor 190 to open only to a certain extent according to the difference between the two, thereby reducing the grouting speed, and conversely, increasing the grouting speed, thus realizing the acceleration and deceleration of grouting. It should be noted that, in this embodiment of the invention, the fourth preset reference value can be set by those skilled in the art according to actual conditions, and this embodiment does not limit it.

Specifically, this embodiment can use a geophysical exploration device 210 to monitor the boundary shape change information of the first solidification 170 and the second solidification 180, thereby obtaining the real-time forming status of the first solidification 170 and the second solidification 180.

[0136] Step 20822: Based on the information on the change in the shape of the second boundary, adjust the opening and closing amplitude of the valve and the grouting direction, and control the extraction flow rate and extraction pressure of the high-pressure pump when injecting grout into the third grouting pipe 130.

[0137] In this embodiment of the invention, the two ends of the first grouting pipe 110 of each layer can be connected to a vertically arranged third grouting pipe 130, and the two ends of the second grouting pipe 120 of each layer can be connected to a vertically arranged third grouting pipe 130. The third grouting pipe 130 can extend upward along the side wall of the soil to be reinforced 100 and connect to the grouting equipment. In this embodiment, grout can be injected into the third grouting pipe 130 through the grouting equipment. The grout can flow through the third grouting pipe 130 to the first grouting pipe 110 and the second grouting pipe 120 of each layer, and after solidification, it can form a first reinforced body 170 and a second reinforced body 180. In this embodiment of the invention, when the geophysical exploration device 210 detects boundary shape change information of the surrounding soil, the MCU can control the high-pressure pump corresponding to the geophysical exploration device 210 to inject grout into the third grouting pipe 130 according to the boundary shape change information.
