[0002] Steel pipe grouting is a common geological disaster control and foundation and rock reinforcement technology. It improves the stability and bearing capacity of the foundation by burying steel pipes underground and performing grouting operations in the pipes. Whether it is tunnel advance steel pipes, radial grouting anchor pipes, locking foot steel pipes or steel pipe grouting of roadbed, slope or surface, the conventional construction method is to push the steel pipe into the rock and soil layer and then weld the grouting connector and ball valve at the end of the steel pipe, and then connect the grouting pipe for grouting.

[0028] As China's manufacturing industry develops towards high-end, intelligent and green directions, the plan clearly proposes to promote the deep integration of new-generation information technology and manufacturing, and promote the optimization and upgrading of industrial structure. The steel pipe grouting technology in geotechnical engineering is a key link in infrastructure construction. By burying steel pipes underground and performing grouting operations in the pipes, the stability and bearing capacity of the foundation can be improved. Whether it is tunnel advance steel pipes, radial grouting anchor pipes, locking foot steel pipes, or steel pipe grouting for roadbed, slope or surface, the conventional construction method is to push the steel pipe into the rock and soil layer and then weld the grouting connector and ball valve at the end of the steel pipe, and then connect the grouting pipe for grouting. The grouting joints mostly use short pipes with external thread joints, but the welding time is often too long, and it takes more time to connect the short pipes with the grouting pipes, which seriously restricts the construction efficiency. In addition, if welding operations are performed in confined spaces such as tunnels, gas explosions are prone to occur, and the short pipes with external thread joints and ball valves are disposable after welding, and cannot be recycled and reused, which increases the construction cost.

[0029] In order to solve the above technical problems, the present invention provides an intelligent grouting system and a grouting method, which adopts a grouting connection set to connect steel flower pipes through adjusting bolts, and connects the grouting connection pipe group, so that installation and disassembly are simple, the safety factor is high in confined space construction, and the construction efficiency is improved. The grouting connection set and the grouting connection pipe group can be recycled for many times, reducing the construction cost.

[0030] In an embodiment of the present invention, the intelligent grouting system comprises: The steel flower pipe 100 has a tip 110 and a tail 120. The tip 110 of the steel flower pipe 100 is used to be buried in the rock layer, and the tail 120 of the steel flower pipe 100 is arranged outside the rock layer. The grouting connection set 200 is connected to the tail end 120 of the steel flower pipe 100 through an adjusting bolt 230; A grouting connection pipe set 300, one end of which is detachably connected to the grouting connection set 200, and the other end of which is used to connect to a grouting pump; A monitoring module for monitoring data of the grouting process; and The controller is respectively connected to the monitoring module and the grouting pump for communication so as to control the operation of the grouting connecting pipe group and the grouting pump according to the data.

[0031] In the technical solution of the present invention, Figure 1 and Figure 2 As shown, the intelligent grouting system includes a grouting connection set 200 and a grouting connection pipe set 300. The steel flower pipe 100 has a tip 110 and a tail end 120. The tip 110 of the steel flower pipe 100 is inserted into the borehole of the rock layer, and the tail end 120 of the steel flower pipe 100 is outside the rock layer. The grouting connection set 200 is connected to the tail end 120 of the steel flower pipe 100 by adjusting the bolt 230, and the grouting connection set 200 is connected to the grouting connection pipe set 300. The grouting connection pipe set 300 is connected to a grouting pump. The grouting pump injects slurry. The slurry enters the steel flower pipe 100 through the grouting connection pipe set 300 and the grouting connection set 200. When the grouting After the grouting is completed, the adjusting bolt 230 is disassembled to disassemble the grouting connection set 200 and the grouting connection pipe set 300. The connection is made through the adjusting bolt 230, which is convenient to realize, has high construction efficiency, is easy to disassemble, and has a high safety factor in a closed environment. After the grouting is completed, the adjusting bolt 230 is loosened to disassemble the grouting connection set 200, so that the grouting connection set 200 can be reused to reduce construction costs. In addition, the intelligent grouting system also includes a monitoring module and a controller. The monitoring module, the grouting pump and the grouting connection pipe set are respectively communicated with the controller. Then, the monitoring module monitors the data of the slurry, including but not limited to the concentration value, pressure value, flow value, speed value, temperature value, etc. of the slurry. The controller integrates the data of the monitoring module and performs real-time analysis to judge and automatically adjust various parameters in the grouting process, so as to achieve precise control, improve the efficiency and quality of the grouting operation, enhance the safety of construction, and realize data traceability. In addition, the intelligent grouting can accurately control the grouting volume and grouting pressure, reduce unnecessary slurry use, reduce the consumption of materials such as cement, reduce the demand and exploitation of natural resources, comply with the principles of green building and sustainable development, and can accurately control and reduce slurry overflow, protect groundwater resources from pollution, and grouting the foundation can significantly improve the stability and durability of the foundation and structure, reduce the maintenance and reconstruction needs caused by unstable foundation, and extend the service life of the building. For disaster-prone areas such as earthquake-prone areas and landslide areas, grouting the foundation can also improve the stability of the foundation and slopes, reduce the impact of disasters, and reinforce and repair the damaged areas to shorten the recovery time.

[0032] Specifically, the steel flower pipe 100 has a tip 110, a tail end 120 and a pipe body, wherein the tip 110 and the tail end 120 are located at both ends of the pipe body, and the pipe body is cylindrical, and a plurality of overflow holes 130 are arranged on the peripheral wall of the pipe body. After the slurry enters the steel flower pipe 100, it penetrates into the rock layer through the overflow holes 130, wherein the number and shape of the overflow holes 130 are not limited, as long as the slurry can pass through the overflow holes 130. In practical applications, it is necessary to excavate the bedrock of the tunnel or spray concrete on the surface of the roadbed and slope rock layer for sealing, and then use drilling equipment such as pneumatic drills, anchor bolters, and rock drilling trolleys to construct the installation hole of the steel flower pipe 100. The steel flower pipe 100 can use a surface or slope reinforcement sleeve valve pipe, an anchor pipe or a tunnel radial grouting anchor pipe, a locking foot anchor pipe or an advance small guide tube, hereinafter collectively referred to as the steel flower pipe 100, and push the steel flower pipe 100 into the installation hole, and at the steel flower pipe 100 A rubber cap is provided at the tail end 120 to plug the steel pipe 100. The installation hole is sprayed with concrete to a certain thickness. The rubber cap can prevent the steel pipe 100 from being blocked when the concrete is sprayed, and the slurry cannot enter the steel pipe 100. The tail end 120 of the steel pipe 100 should be exposed to the concrete for a length of 5-10 cm. After the concrete reaches a certain strength, the rubber cap at the tail end 120 of the steel pipe 100 is removed, and then the grouting connection set 200 is connected to the tail end 120 of the steel pipe 100, and the grouting connection pipe set 300 and the grouting pump are connected to the other end of the grouting connection set 200, and the grouting pump is turned on for grouting. The slurry fills the steel pipe 100, the rivet pipe hole, the cracks or holes in the rock and soil layer, and the holes behind the sprayed concrete through the overflow hole 130 in the steel pipe 100. After the grouting is completed, the grouting is stopped, and the grouting connection pipe set 300 and the grouting connection set 200 are removed in turn.

[0033] In addition, threaded holes are drilled in the circumferential direction of the grouting connection set 200, and nuts 232 are welded on the outer wall of the drilled holes. The adjusting bolts 230 pass through the nuts 232 and the threaded holes and are threadedly connected with the nuts 232 to fix the grouting connection set 200 on the steel flower pipe 100 to achieve the connection. A ring 231 is welded on the nut of the adjusting bolt 230 so that the tightness of the adjusting bolt 230 and the nut 232 can be achieved by twisting the ring 231, which is easy and labor-saving.

[0034] Optionally, the grouting connection set 200 includes: The mounting sleeve 210 is provided with a receiving cavity with one end opened, and the tail end 120 of the steel flower tube 100 extends into the receiving cavity from the opening. The adjusting bolt 230 is provided on the outer peripheral wall of the mounting sleeve 210, and one end of the adjusting bolt 230 extends into the receiving cavity to clamp the steel flower tube 100; At least one first mounting tube 220 is provided. The first mounting tube 220 is disposed in the mounting sleeve 210 and extends in a direction away from the tip 110 of the steel flower tube 100 . One end of the first mounting tube 220 leads to the accommodating cavity, and the other end is connected to the grouting connecting tube group 300 .

[0035] In this embodiment, if Figure 3 As shown, the grouting connection set 200 includes a mounting sleeve 210 and a first mounting tube 220. The mounting sleeve 210 is cylindrical and has a receiving cavity with an opening at one end. The tail end 120 of the steel flower pipe 100 extends into the receiving cavity at the opening. The inner diameter of the mounting sleeve 210 is 1-2 cm larger than the diameter of the steel flower pipe 100. The wall thickness of the mounting sleeve 210 is 3-5 mm optimally. One end of the first mounting tube 220 passes through the mounting sleeve 210 and extends into the receiving cavity, and is welded to the mounting sleeve 210. The other end of the first mounting tube 220 is connected to the grouting connection pipe set 300, wherein at least one first mounting tube 220 is provided. When one first mounting tube 220 is provided, the first mounting tube 220 adopts a straight structure. If multiple first mounting tubes 220 are provided, the portion of the first mounting tube 220 extending into the receiving cavity is a straight structure, and the portion outside the receiving cavity is inclined at an angle to the portion inside the receiving cavity. In this embodiment, two first mounting tubes 220 are used. Figure 3 As shown, the two first mounting tubes 220 are in an "eight"-shaped structure, and the bending angle of the portion outside the accommodating cavity is 120°.

[0036] Furthermore, the intelligent grouting system also includes: The slurry stopper 400 is located in the accommodating cavity. One end of the slurry stopper 400 is inserted into the tail end 120 of the steel flower tube 100, and the other end is outside the steel flower tube 100. The slurry stopper 400 is provided with at least one slurry flow hole 410 along its own axial direction. The slurry flow hole 410 is communicated with the steel flower tube 100. The slurry flow hole 410 is correspondingly arranged with the first mounting tube 220, and each first mounting tube 220 extends into a corresponding slurry flow hole 410, so that the slurry is guided into the steel flower tube 100 through the first mounting tube 220 and the slurry flow hole 410; The cover plate 420 is arranged on the slurry stopping plug 400 at one end inside the steel flower pipe 100. The cover plate 420 has a first state and a second state. In the first state, the slurry passes through the slurry flow hole 410 and drives the cover plate 420 to leave the slurry flow hole 410 to achieve grouting into the steel flower pipe 100. In the second state, after the grouting stops, the slurry drives the cover plate 420 in the opposite direction to move toward the slurry flow hole 410 to block the slurry flow hole 410 to stop the slurry.

[0037] In this embodiment, the intelligent grouting system further includes a grout stopper 400 and a cover plate 420. Figure 6As shown, the slurry stopper 400 is arranged at the tail end 120 of the steel flower pipe 100, one end of which is inserted into the steel flower pipe 100, and the other end of which is outside the steel flower pipe 100 and in the accommodating cavity. The slurry stopper 400 is made of rubber material. The slurry stopper 400 is inserted into the steel flower pipe 100. The portion of the slurry stopper 400 inside the steel flower pipe 100 is 4-6 mm smaller than the diameter of the steel flower pipe 100, and the portion of the slurry stopper 400 outside the steel flower pipe 100 is 4-6 mm larger than the diameter of the steel flower pipe 100. The slurry stopper 400 is provided with a slurry flow hole 410 along its own axial direction, and the slurry flow hole 410 is communicated with the steel flower pipe 100. The portion of the first installation tube 220 in the accommodating cavity extends into the slurry flow hole 410, and the slurry enters the slurry flow hole 410 in the first installation tube 220 and then enters the steel flower pipe 100. When the slurry flows through the slurry flow hole 410, the pressure of the slurry flow causes the slurry stopper 400 to deform, and the portion of the slurry stopper 400 in the steel flower pipe 100 is deformed to achieve complete fit with the inner wall of the steel flower pipe 100 to prevent slurry leakage, wherein at least one slurry flow hole 410 is provided, and the number of the slurry flow holes 410 is determined according to the type of slurry, and the number of the slurry flow holes 410 corresponds to the number of the first installation tubes 220, such as Figure 7-8 As shown, if only one slurry flow hole 410 is provided, it can be provided at the center of the slurry stopper 400 or at the periphery thereof so as to connect the first mounting pipe 220. In this case, the slurry type is one, namely, single-liquid slurry; Figure 9-10 As shown, if multiple slurry flow holes 410 are provided, except for the center of the slurry stopper 400, they are equally divided according to the number of holes. Double-liquid slurry uses two holes, and triple-liquid slurry uses three holes. Figure 7-10 The arrangement is shown as a single hole, two holes and three holes, and the radius of the slurry hole 410 decreases from the tail end 120 to the tip 110 of the steel flower pipe 100, which is convenient for the first installation tube 220 to be inserted into the slurry hole 410 and for the slurry to flow into the steel flower pipe 100; in addition, the cover plate 420 is arranged at one end of the slurry stop plug 400 in the steel flower pipe 100, and is connected to the slurry stop plug 400 by bolts, and the bolts are installed in the middle of the slurry stop plug 400. The cover plate 420 is set to a rubber material and the thickness can be The thickness of the cover plate 420 is 4-6 mm, which is prone to deformation. When there is no grouting, the cover plate 420 blocks the slurry flow hole 410. When grouting is in progress, the slurry is in the slurry flow hole 410, and the pressure pushes the cover plate 420 open, causing the cover plate 420 to deform. The slurry flows out from the gap between the cover plate 420 and the slurry stop plug 400 and flows toward the steel flower pipe 100. After the grouting is completed, the slurry in the steel flower pipe 100 pushes the cover plate 420 in the opposite direction to snap onto the slurry stop plug 400 to close the slurry flow hole 410, thereby achieving the purpose of stopping slurry.

[0038] Optionally, the grouting connection pipe set 300 includes: The slurry flow pipe 310 is disposed at one end of the first mounting pipe 220 away from the mounting sleeve 210, and the first mounting pipe 220 extends into the slurry flow pipe 310; Two handles 320 are provided. The two handles 320 are disposed on the outer periphery of the slurry flow pipe 310 , and the two handles 320 are hinged to the slurry flow pipe 310 to clamp or release the first installation pipe 220 .

[0039] In this embodiment, if Figure 4 As shown, the grouting connection pipe group 300 includes a slurry pipe 310 and a handle 320. The handle 320 is arranged on the outer wall of the slurry pipe 310 and is hinged to the slurry pipe 310. The first installation pipe 220 extends into the slurry pipe 310 at one end outside the accommodating cavity, and the first installation pipe 220 is clamped by the handle 320 outside the slurry pipe 310. The other end of the slurry pipe 310 is connected to the grouting pump. The slurry flows out of the grouting pump and enters the slurry pipe 310 and the first installation pipe 220, and then enters the steel flower pipe 100 to complete the grouting. When the grouting is completed, the grouting pump is turned off to avoid waste caused by continuous outflow of slurry. Specifically, the grouting pump is communicated with the controller. The controller can adjust the grouting pressure value and the slurry flow rate by controlling the working state of the grouting pump according to the monitoring data of the monitoring module.

[0040] Optionally, the grouting connection pipe set 300 further includes a gasket, which is disposed in the slurry flow pipe 310 to seal the connection between the slurry flow pipe 310 and the first installation pipe 220 .

[0041] In this embodiment, the gasket is arranged on the inner wall of the slurry flow pipe 310, so that the slurry flow pipe 310 and the first installation pipe 220 can be closely fitted to prevent slurry leakage.

[0042] Optionally, the tube wall of the first installation tube 220 is radially recessed toward the inside of the tube, and the handle 320 is arranged corresponding to the recess of the first installation tube 220 .

[0043] In this embodiment, as shown in 4 and Figure 5 As shown, the portion of the first mounting tube 220 extending into the slurry tube 310 is recessed inwardly along its own radial direction, and the handle 320 is provided on the slurry tube 310 corresponding to the recess, and the handle 320 is hinged to the slurry tube 310 through a hinge seat. When the handle 320 is rotated to a perpendicular state to the slurry tube 310, the slurry tube 310 is in a relaxed state, and when the handle 320 is rotated to a parallel state to the slurry tube 310, the hinge seat is rotated to protrude inwardly. If the first mounting tube 220 is in the slurry tube 310, the hinge seat is hinged to the recess of the first mounting tube 220, which can prevent the first mounting tube 220 and the slurry tube 310 from detaching.

[0044] Furthermore, the grouting connection pipe group 300 also includes: The steel pipe 330 is disposed at one end of the slurry pipe 310 away from the first mounting pipe 220 and is fixedly connected to the slurry pipe 310; A grouting pipe 340 is provided at one end of the steel pipe 330 away from the grouting pipe 310, one end of the grouting pipe 340 is connected to the steel pipe 330, and the other end is connected to the grouting pump; The ball valve 350 is disposed on the steel pipe 330 and is connected in communication with the controller to start grouting or stop grouting.

[0045] In this embodiment, a steel pipe 330 is connected to one end of the slurry pipe 310 away from the first installation pipe 220, a ball valve 350 is installed on the steel pipe 330, the other end of the steel pipe 330 is connected to the grouting pipe 340, the grouting pipe 340 is connected to the grouting pump, the grouting pump and the ball valve 350 are turned on, the slurry enters the slurry pipe 310 and the first installation pipe 220 through the grouting pipe 340 and the steel pipe 330 and then enters the steel flower pipe 100, completing the grouting. After the grouting is completed, the ball valve 350 is closed to avoid continuous outflow of slurry and waste, wherein the ball valve 350 is communicatively connected to the controller, and the controller controls the valve opening of the ball valve 350 to adjust the flow rate of the slurry.

[0046] Furthermore, the intelligent grouting system also includes an exhaust pipe 500 , one end of which extends into the steel flower pipe 100 , so that the gas in the steel flower pipe 100 can be discharged through the exhaust pipe 500 after the slurry enters the steel flower pipe 100 .

[0047] In this embodiment, an exhaust pipe 500 is arranged in the steel flower pipe 100, one end of the exhaust pipe 500 extends into the interior of the steel flower pipe 100, and the other end is located outside the steel flower pipe 100, so that the inside and outside of the steel flower pipe 100 are connected through the exhaust pipe 500, and grouting is injected into the steel flower pipe 100 by a grouting pump. As the pressure increases, the gas and residual water in the steel flower pipe 100 will be pushed out with the slurry until the exhaust valve starts to flow out of the slurry, which proves that the gas is basically exhausted, and the exhaust pipe 500 is blocked. By setting the exhaust pipe 500, it is convenient to discharge the gas in the steel flower pipe 100, better inject the slurry, avoid the generation of bubbles or cavities due to the gas during the grouting process, and ensure the density and structural strength of the grouting body.

[0048] Specifically, when injecting slurry into the steel flower pipe 100, when the steel flower pipe 100 is full of slurry, the slurry will overflow in the exhaust pipe 500. When the slurry is seen overflowing from the mouth of the exhaust pipe 500, the ball valve 350 can be closed, and a wedge-shaped wooden stick can be inserted into the mouth of the exhaust pipe 500 to block the exhaust pipe 500.

[0049] Furthermore, the intelligent grouting system also includes a guide pipe 510, which is fixed to the pipe wall of the steel flower pipe 100 near the tail end 120. The pipe body of the steel flower pipe 100 is provided with a third through hole 160 near the tail end 120, and the exhaust pipe 500 passes through the guide pipe 510 and the third through hole 160 to enter the steel flower pipe 100.

[0050] In this embodiment, the guide pipe 510 is arranged near the tail end 120 of the steel flower pipe 100, and the exhaust pipe 500 passes through the guide pipe 510 and the guide pipe 510 to enter the steel flower pipe 100. By setting the guide pipe 510, it is convenient to fix and limit the exhaust pipe 500 to prevent the exhaust pipe 500 from falling off in the steel flower pipe 100 during the grouting process, thereby affecting the exhaust effect.

[0051] Furthermore, the steel flower tube 100 has a third state and a fourth state. In the third state, the tip 110 of the steel flower tube 100 is lower than the tail end 120 of the steel flower tube 100, and one end of the exhaust pipe 500 enters the steel flower tube 100 and is close to the tail end 120. In the fourth state, the tip 110 of the steel flower tube 100 is higher than the tail end 120 of the steel flower tube 100 and / or the steel flower tube 100 is arranged horizontally, and one end of the exhaust pipe 500 enters the steel flower tube 100 and is close to the tip 110 .

[0052] In this embodiment, if the tip 110 of the steel flower pipe 100 is facing downward, the steel flower pipe 100 is in the third state at this time, one end of the exhaust pipe 500 passes through the guide pipe 510, and then passes through the third through hole 160 to enter the steel flower pipe 100, and it is only necessary for the pipe mouth of the exhaust pipe 500 to be in the steel flower pipe 100, that is, one end of the exhaust pipe 500 in the steel flower pipe 100 is close to the tail end 120, saving the material of the exhaust pipe and reducing the cost. At this time, during grouting, the slurry falls under the action of gravity, and the air overflows from the exhaust pipe 500 from bottom to top under the pressure of the slurry; when the tip 110 of the steel flower pipe 100 is higher than the tail end 120 or the steel flower pipe 100 is horizontally arranged, the steel flower pipe 100 is in the fourth state, and the exhaust pipe 500 passes through the guide pipe 510 and the third through hole 160. The hole 160 enters the steel flower pipe 100 and extends inwardly into the steel flower pipe 100 to be set near the tip 110. When grouting is injected inwardly at the tail end 120 of the steel flower pipe 100, since the tip 110 is higher than the tail end 120, after the slurry enters the tail end 120, it cannot be affected by gravity to approach the tip 110, and can only accumulate at the tail end 120, and the tip 110 and the internal gas in the steel flower pipe 100 cannot be discharged. When the slurry is close to the tip 110 in the steel flower pipe 100, the internal gas enters the exhaust pipe 500 through the inside of the steel flower pipe 100 near the tip 110. As the accumulated slurry in the steel flower pipe 100 gradually approaches the tip 110, the gas in the steel flower pipe 100 is pressed into the exhaust pipe 500 at the tip 110 position, and then outside the steel flower pipe 100.

[0053] Furthermore, a first through hole 140 is provided at the end of the tip 110 of the steel flower pipe 100, and a second through hole 150 is provided on the body of the steel flower pipe 100 near the tip 110. In the fourth state, the exhaust pipe 500 passes through the guide pipe 510 and the third through hole 160 in sequence to enter the steel flower pipe 100, and passes through any one of the first through hole 140 and the second through hole 150 to pass out of the steel flower pipe 100, and then passes through the other of the first through hole 140 and the second through hole 150 to enter the steel flower pipe 100.

[0054] In this embodiment, if Figure 1 and Figure 2 As shown, in order to fix the exhaust pipe 500, a guide pipe 510 is arranged on the steel flower pipe 100 to prevent the exhaust pipe 500 from being separated from the steel flower pipe 100. A first through hole 140, a second through hole 150 and a third through hole 160 are respectively arranged at the tip 110 end of the steel flower pipe 100, a position of the pipe body close to the tip 110 and a position of the pipe body close to the tail end 120. When the steel flower pipe 100 is in the fourth state, that is, the tip 110 faces upward or the steel flower pipe 100 is arranged horizontally, the exhaust pipe 500 passes through the guide pipe 510 and the third through hole 160 to enter the steel flower pipe 100, and then passes through the first through hole 140 to be folded outside the steel flower pipe 100. The exhaust pipe 500 bends through the second through hole 150 to enter the steel flower pipe 100, or after the exhaust pipe 500 enters the steel flower pipe 100, it first passes through the second through hole 150, passes out of the steel flower pipe 100, and then bends and enters the steel flower pipe 100 from the first through hole 140 to fix the exhaust pipe 500 to prevent the exhaust pipe 500 from shaking in the steel flower pipe 100 and affecting the exhaust effect when the slurry is injected. The other end of the exhaust pipe 500 extends out of the guide pipe 510 and is outside the re-sprayed concrete. At this time, when the slurry is injected into the steel flower pipe 100, as the slurry in the steel flower pipe 100 increases, the air below / inside the steel flower pipe 100 can overflow in the exhaust pipe 500 under the pressure.

[0055] Optionally, one steel flower tube 100 is provided, and one guide tube 510 is provided correspondingly, and is provided near the tube wall of the tail end 120 of the steel flower tube 100 .

[0056] In this embodiment, when one steel flower tube 100 is provided, one guide tube 510 is provided correspondingly, and the opening direction of the guide tube 510 varies with the position of the steel flower tube 100. In the third state, the tip 110 is lower than the tail end 120, and the guide tube 510 opens upward. In the fourth state, the tip 110 is higher than the tail end 120, or the steel flower tube 100 is placed horizontally, and the guide tube 510 opens downward.

[0057] Furthermore, a plurality of steel flower pipes 100 are provided, and two guide pipes 510 are provided to connect each steel flower pipe 100, and the two guide pipes 510 are symmetrically arranged on the peripheral wall of the steel flower pipe 100. The intelligent grouting system also includes a connecting pipe 520, and the connecting pipe 520 extends into the steel flower pipe 100 through the guide pipe 510. The guide pipes 510 between two adjacent steel flower pipes 100 are connected through the connecting pipe 520, so that when the grouting of one of the steel flower pipes 100 is completed, the excess slurry in the steel flower pipe 100 enters the adjacent steel flower pipe 100 through the connecting pipe 520 for grouting, so as to realize the cyclic grouting of multiple steel flower pipes 100.

[0058] In this embodiment, when multiple steel flower pipes 100 are provided, two guide pipes 510 are connected to each steel flower pipe 100, and the two guide pipes 510 are symmetrically arranged on the outer tube wall of each steel flower pipe 100. A connecting pipe 520 is arranged between two adjacent steel flower pipes 100, and both ends of the connecting pipe 520 extend into the steel flower pipe 100 through the guide pipes 510 respectively, so that circular grouting between multiple steel flower pipes 100 can be realized. First, slurry is injected into the steel flower pipe 100 at the edge. When the steel flower pipe 100 is full, the slurry overflows in the exhaust hole and enters the adjacent steel flower pipe 100 through the connecting pipe 520 to avoid waste of slurry. The two exhaust pipes 500 in the first steel flower pipe 100 injected with slurry, one is connected to the adjacent steel flower pipe 100 through the connecting pipe 520, and the other can be blocked by a wedge-shaped wooden stick when the slurry overflows, and the ball valve 350 is closed in time. Specifically, it can move flexibly. In this embodiment, Fig.11 As shown, three steel flower pipes 100 are set, and the tips 110 of the steel flower pipes 100 from top to bottom are respectively facing upward, horizontally arranged, and downwardly arranged. When grouting is performed, the grouting connection set 200 and the grouting connection pipe set 300 are first connected to the lowest steel flower pipe 100, and the tip 110 of the lowest steel flower pipe 100 faces downward, so that the exhaust pipe 500 enters the steel flower pipe 100 through the guide pipe 510 and the third through hole 160. When the slurry in the lowest steel flower pipe 100 is filled, the slurry is discharged in the exhaust pipe 500 and enters the middle steel flower pipe 100 through the connecting pipe 520. At this time, the ball valve 350 is closed, the grouting connection set 200 is disassembled, and the grouting The slurry connection set 200 and the grouting connection pipe set 300 are connected to the middle steel flower pipe 100. An exhaust pipe 100 is arranged in the middle steel flower pipe 100, extending into the steel flower pipe 100 and arranged near the tip 110, and the exhaust pipe 100 is connected to the connecting pipe 520. After the middle steel flower pipe 100 is filled, the slurry enters the uppermost steel flower pipe 100 through the connecting pipe 520. An exhaust pipe 500 is arranged in the uppermost steel flower pipe 100, extending into the steel flower pipe 100 and arranged near the tip 110. Repeat the above steps to grout the uppermost steel flower pipe 100, so as to realize the circular grouting of multiple steel flower pipes 100. The connecting pipe 520 can avoid the waste of slurry and improve the grouting efficiency.

[0059] Optionally, the monitoring module includes: Pressure sensor, which is installed at the outlet of the grouting pump and at the connection between the grouting connection set and the steel pipe to detect the grouting pressure; A flow sensor is arranged at the outlet of the grouting pump, the grouting connection set and / or the grouting connection pipe set and / or the steel flower pipe to detect the grouting speed; The displacement sensor is arranged in the rock and soil layer of the outer wall of the steel pipe to detect the displacement of the rock and soil layer during the grouting process.

[0060] In this embodiment, the pressure sensor is usually installed at the outlet of the grouting pump, the key nodes of the grouting pipeline, and the monitoring hole near the grouting point. For example, it can be installed at the outlet of the grouting pump, the grouting connection set and the connection of the steel pipe in the specific implementation. By real-time monitoring of the grouting pressure, it is ensured that the grouting is carried out within the designed pressure range to avoid structural damage caused by excessive pressure or insufficient slurry penetration caused by too low pressure. If the pressure deviates from the set range, the controller will automatically adjust the working state of the grouting pump and adjust the grouting pressure to the predetermined value.

[0061] Flow sensors are usually placed at the outlet of the grouting pump, the grouting connection set and / or the grouting connection pipe set and / or the steel pipe to monitor the flow rate of the slurry in real time and automatically adjust the grouting speed according to the set flow curve to ensure that the slurry is injected evenly and in the right amount. If the flow data indicates that the grouting rate is too fast or too slow, the control system will adjust the pump speed or valve opening to maintain the ideal grouting rate.

[0062] The displacement sensor is installed around or inside the construction area, such as the tunnel wall, building foundation, foundation, etc. For example, in this embodiment, it is installed in the rock layer to monitor the small displacement of the stratum during the grouting process to evaluate the grouting effect and stratum stability. If the displacement exceeds the allowable range, it may be necessary to adjust the grouting strategy or stop grouting to avoid unnecessary structural damage.

[0063] In addition, the monitoring module can also include a density sensor, which is usually integrated in the pulping equipment, especially in the slurry output pipeline after mixing, to detect the slurry concentration and density in real time to ensure that the slurry meets the design specifications and avoid poor filling effects due to improper density. If the concentration and density are detected to deviate from the set value, the system can automatically adjust the slurry composition, such as increasing or decreasing the amount of additives.

[0064] The monitoring module may also include other sensors, including but not limited to temperature sensors, vibration sensors and sensors for detecting soil pressure, which are arranged at key points as needed, such as grouting areas, surrounding environments or specific monitoring points. The data provided by these sensors are used to assist decision-making, such as adjusting grouting parameters to adapt to environmental changes, or monitoring the impact of construction on the surrounding environment to ensure construction safety.

[0065] By integrating the data from these sensors, the controller can analyze, judge and automatically adjust various parameters in the grouting process in real time, thereby achieving precise control, improving the efficiency and quality of grouting operations, reducing human errors, and enhancing construction safety. This closed-loop control strategy ensures the optimization of the construction process.

[0066] The present invention also provides a steel flower pipe grouting method, which adopts the above-mentioned intelligent grouting system and comprises the following steps: S10, one end of the steel flower tube 100 is pointed as the tip 110, and the other end is used as the tail end 120, and the tip 110 of the steel flower tube 100 is extended into the drilled hole of the rock layer, and the tail end 120 of the steel flower tube 100 is outside the drilled hole; S20, protecting the tail end 120 of the steel flower tube 100, and spraying concrete on the surface of the rock layer to close the gap between the steel flower tube 100 and the drill hole; S30, removing the protection of the tail end 120 of the steel flower pipe 100, and connecting the grouting connection set 200 at the tail end 120 through the adjusting bolt 230, the grouting connection set 200 is connected to the grouting pump through the grouting connection pipe set 300, and the slurry is mixed before grouting; S40, turn on the grouting pump, the slurry passes through the grouting connection pipe group 300 and the grouting connection set 200 in sequence, and enters the steel flower pipe 100, the monitoring module detects the parameters of the slurry and the displacement data of the rock and soil layer during the grouting process, and controls the working state of the grouting pump and the grouting connection pipe group 300 through the controller; S50, after grouting is completed, the grouting pump is turned off, and the tail end 120 of the steel flower pipe 100 is blocked to stop the grouting; the adjusting bolt 230 is loosened to separate the grouting connection set 200 from the tail end 120 of the steel flower pipe 100.

The grouting connection pipe set 300 and the grouting pump are connected at the other end of the grouting connection set 200. By starting the grouting pump, the slurry is connected through the grouting connection set 200. The pipe group 300 and the grouting connection set 200 enter the steel flower pipe 100 to realize grouting. After the grouting is completed, the adjusting bolt 230 is loosened to realize the separation of the grouting connection set 200 and the steel flower pipe 100, which is convenient for the secondary use of the grouting connection set 200, reduces the construction cost, and improves the safety of construction. In addition, the intelligent grouting system also includes a monitoring module and a controller. The monitoring module, the grouting pump and the grouting connection pipe group are respectively connected to the controller for communication.

For disaster-prone areas such as earthquake-prone areas and landslide areas, grouting the foundation can also improve the stability of the foundation and slopes and reduce the impact of disasters. For damaged areas, they can be reinforced and repaired to shorten the recovery time.

[0068] Specifically, when the steel flower pipe 100 is inserted into the drill hole, it is necessary to install the exhaust pipe 500 and the slurry stopper 400. Specifically, when installing the exhaust pipe 500, a first through hole 140 is set at the end of the tip 110 of the steel flower pipe 100, a second through hole 150 is set near the tip 110 of the steel flower pipe 100, a third through hole 160 is set near the tail end 120 of the steel flower pipe 100, and a guide pipe 510 is set near the tail end 120 of the steel flower pipe 100.
