Description

Technical Field

[0001] This application relates to the field of wall repair, and in particular to a method for grouting and reinforcing basement exterior walls and a drilling grouting device. Background Technology

[0002] Prefabricated shear walls allow for the prefabrication of walls in a factory, followed by transportation to the site for installation, saving construction time. Shear wall installation typically involves connecting pre-embedded sleeves at the bottom of the prefabricated shear wall to pre-embedded reinforcing bars in the cast-in-place wall base, creating a horizontal joint between the bottom of the prefabricated shear wall and the cast-in-place wall base. Grouting is then applied to the sleeves to secure the prefabricated shear wall. However, in basements, the external walls face pressure from the surrounding soil and water, making these horizontal joints prone to seepage. Therefore, timely sealing of the basement walls is necessary.

[0003] The existing public method for grouting and reinforcing construction joints of basement exterior walls, with publication number CN111809670A, involves drilling holes at the leaking points of the basement exterior wall to form several rows of grouting holes. Then, grout prepared with corresponding grouting materials is injected into the grouting holes under a certain pressure, forming a consolidation zone on one side of the outer surface of the basement exterior wall, thereby preventing groundwater from seeping through the bottom of the wall.

[0004] Regarding the aforementioned technologies, whether the grouting on the outer side of the basement exterior wall is complete cannot be directly observed. Instead, it can only be indirectly understood through the pressure reading on the grouting pressure gauge. It is difficult to know whether the area between two adjacent rows of grouting holes on the outer side of the exterior wall is filled with grout, making it difficult to effectively obtain the grouting progress. Summary of the Invention

[0005] In order to more effectively control the grouting progress, this application provides a method for grouting and reinforcing basement exterior walls and a drilling grouting device.

[0006] The technical solution provided in this application for a method of grouting and reinforcing basement exterior walls to stop leaks is as follows.

[0007] A method for grouting and reinforcing basement exterior walls, specifically including the following steps.

[0008] Step 1: Clean the inner surface of the wall;

[0009] Step 2: Drill holes on the inner surface of the wall to form several rows of grouting holes, with one grouting hole in each row located on both the upper and lower sides of the horizontal joint;

[0010] Step 3: Drill holes on the inner surface of the wall to form several grout outlet holes. The grout outlet holes are located at the horizontal joints, and one grout outlet hole is set on both sides of each row of grouting holes.

[0011] Step 4: Insert the grouting pipe tightly into the grouting hole to inject grout, and insert the grout outlet pipe tightly into the grout outlet hole until grout flows out of the grout outlet pipe, then stop grouting;

[0012] Step 5: Seal the grouting pipe and the grout outlet pipe.

[0013] By adopting the above technical solution, grout outlet holes are opened at a certain distance on both sides of each row of grouting holes. This ensures that grout will flow out of the outlet holes only when the area between two corresponding outlet holes on the outside of the wall is filled with grout. Otherwise, the grout will not flow out of the outlet holes. This allows for better control of the grouting progress on the outside of the wall, ensuring sufficient grouting and improving the grouting quality.

[0014] This application also provides a drilling grouting device using the following technical solution.

[0015] A drilling and grouting device, used according to the above-mentioned method for grouting and reinforcing basement exterior walls, includes a base, a vertical member slidably connected to the base, two grouting drills slidably connected to the vertical member for forming a row of grouting holes and a grouting drill for forming two grouting holes, a push cylinder mounted on the vertical member that can drive the grouting drill and the grouting drill closer to the wall, a grouting insertion device mounted on the vertical member for inserting a grouting pipe into the grouting hole and a grouting insertion device for inserting a grouting pipe into the grouting hole, and a grouting pump mounted on the base for feeding grout into the grouting pipe.

[0016] By adopting the above technical solution, each time two grouting holes and two grout outlet holes are formed in a row, the corresponding grouting pipes and grout outlet pipes are inserted into the corresponding holes in the wall, and then grouting is started. This ensures that the grout will only flow out from the end of the grout outlet pipe located inside the wall when a certain amount of grout has flowed to the grout outlet pipe, so that grouting can be stopped in time.

[0017] Optionally, the upright includes a cross-shaped component fixedly connected to the base, two upper and lower blocks and two left and right blocks rotatably connected to the cross-shaped component, and a shifting electric cylinder located on the cross-shaped component and driving the upper and lower blocks and the left and right blocks to rotate. The upper and lower blocks are respectively provided with grouting drilling machines and grouting pipe insertion devices at their respective ends, and the left and right blocks are respectively provided with grout discharge drilling machines and grout discharge pipe insertion devices at their respective ends.

[0018] By adopting the above technical solution, after the drilling of grouting holes and grout outlet holes is completed, the upper and lower blocks and the left and right blocks can be rotated to facilitate the subsequent insertion of grouting pipes and grout outlet pipes into the corresponding walls, which is more convenient.

[0019] Optionally, the grouting insertion device includes a grouting slide pipe slidably connected to the upper and lower blocks, a threaded pipe rotatably connected to the grouting slide pipe and threadedly connected to the inner wall of the grouting pipe, a guide rod fixedly connected to the grouting slide pipe and inserted into the end face of the grouting pipe, and a threaded pipe motor provided on the grouting slide pipe and driving the threaded pipe to rotate.

[0020] By adopting the above technical solution, the grout is less likely to leak from the connection between the threaded pipe and the grouting pipe, and it is also easier to unscrew the threaded pipe out of the grouting pipe.

[0021] Optionally, the grouting slide includes a sleeve for the threaded pipe, guide rod and threaded pipe motor, an insert pipe inserted into and connected to the sleeve for grout to pass through, and a transfer pipe connected to the end of the insert pipe away from the sleeve and slidably connected to the upper and lower blocks. A sleeve spring is provided between the sleeve and the transfer pipe to force the sleeve to move closer to the transfer pipe. The insert pipe is fixedly connected to a pipe ring that can abut against the end face of the sleeve facing the transfer pipe.

[0022] By adopting the above technical solution, after grouting is completed, the pipe is moved away from the grouting pipe so that the pipe ring no longer abuts against the sleeve. Then, the threaded pipe is rotated until it is disengaged from the grouting pipe. The sleeve spring will then drive the sleeve to abut against the pipe ring so as to disassemble the threaded pipe and the grouting pipe.

[0023] Optionally, a tube gear is coaxially fixedly connected to one end of the exposed grouting pipe of the threaded pipe, and a motor gear meshing with the tube gear is coaxially fixedly connected to the output shaft of the threaded pipe motor.

[0024] By adopting the above technical solution, the threaded pipe can be rotated and the grouting pipe can be connected or disconnected.

[0025] Optionally, the slurry outlet tube device includes a slurry outlet slide tube slidably connected to the left and right blocks, an insert rod fixedly connected to the slurry outlet slide tube and inserted into the end face of the slurry outlet tube, and a pipe port for slurry to flow out is provided through the bottom of the slurry outlet slide tube.

[0026] By adopting the above technical solution, the grouting progress can be better controlled while making it easier to insert the grouting pipe into the grouting hole.

[0027] Optionally, the push cylinder power rod is fixedly connected to a synchronizing element. The synchronizing element is detachably connected to upper and lower push rods for each of the two upper and lower blocks, and detachably connected to left and right push rods for each of the two left and right blocks. The upper and lower push rods and the left and right push rods are slidably connected to the cross element. The upper and lower push rods can drive the grouting drilling machine or grouting slide pipe to move, and the left and right push rods can drive the grouting drilling machine or grouting slide pipe to move.

[0028] By adopting the above technical solution, the upper and lower push rods and the left and right push rods can move synchronously, so as to simultaneously form the grouting hole and the grout outlet hole, and insert the grouting pipe and the grout outlet pipe into the wall.

[0029] Optionally, the grouting drilling machine, grouting slide pipe, grouting drilling machine, and grouting slide pipe are all fixedly connected to the side blocks. The upper and lower push rods and the left and right push rods are each inserted into a side block. The side block is slidably connected to a plug-in post that can be inserted into the upper and lower push rods or the left and right push rods. The end of the plug-in post facing the upper and lower push rods or the left and right push rods is fixedly connected to a hemisphere that is inserted into the upper and lower push rods or the left and right push rods. The side block is provided with an internal spring that pushes the plug-in post to move towards the upper and lower push rods or the left and right push rods.

[0030] By adopting the above technical solution, when the drilling is completed and the grouting drilling machine and the grouting drilling machine need to be moved back, or when the grouting slide pipe and the grouting slide pipe need to be moved back after grouting is completed, the movement of the upper and lower push rods and the left and right push rods away from the wall will cause the plug-in column to move synchronously, so that the corresponding grouting drilling machine and the grouting drilling machine, or the grouting slide pipe and the grouting slide pipe can be moved back. Furthermore, due to the insertion of the hemispherical shape, the upper and lower push rods or the left and right push rods can be disengaged from the side block, so that the upper and lower blocks and the left and right blocks can rotate.

[0031] Optionally, an inner inclined wedge block is fixedly connected to one end of the plug-in post near the inner spring of the block, and an outer inclined wedge block is fixedly connected to the cross member, which can be inserted into the side block and abut against the inner inclined wedge block so that only the hemisphere is located in the upper and lower push rods or the left and right push rods.

[0032] By adopting the above technical solution, when the drilling is completed and the grouting drilling machine and the grouting drilling machine need to be moved back, or when the grouting slide pipe and the grouting slide pipe need to be moved back after grouting is completed, the insert column body will be located inside the upper and lower push rods or the left and right push rods, so that the grouting drilling machine, the grouting drilling machine, the grouting slide pipe and the grouting slide pipe can be stably driven to move. When the grouting drilling machine and the grouting drilling machine are moved back to their positions, or when the grouting slide pipe and the grouting slide pipe are moved back to their positions, the outer inclined wedge will push the inner inclined wedge to move, so that only the hemisphere is located inside the upper and lower push rods or the left and right push rods, so that the upper and lower push rods or the left and right push rods are disengaged from the side block.

[0033] In summary, this application includes at least one of the following beneficial effects:

[0034] 1. This allows for better control over the grouting progress on the outside of the wall, ensuring sufficient grouting and improving the grouting quality.

[0035] 2. After drilling the grouting holes and grout outlet holes, the upper and lower blocks and the left and right blocks can be rotated to facilitate the subsequent insertion of the grouting pipes and grout outlet pipes into the corresponding walls, which is quite convenient.

Detailed Implementation

[0043] The present application will be further described in detail below with reference to the accompanying drawings.

[0044] This application discloses a method for grouting and reinforcing basement exterior walls, which includes the following steps.

[0045] Step 1: Clean the inner surface of the wall;

[0046] Step 2: Drill holes on the inner surface of the wall to form several rows of grouting holes, with one grouting hole in each row located on both the upper and lower sides of the horizontal joint;

[0047] Step 3: Drill holes on the inner surface of the wall to form several grout outlet holes. The grout outlet holes are located at the horizontal joints, and one grout outlet hole is set on both sides of each row of grouting holes.

[0048] Step 4: Insert the grouting pipe 1 tightly into the grouting hole to inject grout, and insert the grout outlet pipe 2 tightly into the grout outlet hole until grout flows out of the grout outlet pipe 2, then stop grouting.

[0049] Step 5: Seal the grouting pipe 1 and the grout outlet pipe 2.

[0050] The implementation principle of the basement exterior wall sealing and grouting reinforcement method in this application embodiment is as follows: when the grouting is sufficient in the area between two grout outlet holes on the outer side of the wall, the grout will flow out from the grout outlet pipe so that the operator knows that the grouting is sufficient.

[0051] This application also discloses a drilling grouting device, which is used according to the above-described method for grouting and reinforcing basement exterior walls, with reference to... Figure 1 The system includes a base 3 with casters for movement, and a hydraulic cylinder at the bottom to lift the base 3 during drilling to ensure stable drilling. An upright 4 is mounted on the upper surface of the base 3, housing two grouting drills 5 and two grouting drills 51. The two grouting drills 5 are connected vertically, and the two grouting drills 51 are connected horizontally. The grouting drills 5 are used to form grouting holes, and the grouting drills 51 are used to form grouting holes. A grouting pump 54 is fixedly connected to the upright 4 to inject grout into the soil layer outside the wall.

[0052] Reference Figure 1 The upright component 4 includes an L-shaped rod 26 fixedly connected to the upper surface of the base 3. The horizontal section of the L-shaped rod 26 has a vertically shaped cross component 55 integrally formed at its end. The vertical cross-shaped surface of the cross component 55 faces the wall. The upper and lower ends of the cross component 55 are rotatably connected to upper and lower blocks 56, and the left and right ends of the cross component 55 are rotatably connected to left and right blocks 57. The rotation axes of the upper and lower blocks 56 and the left and right blocks 57 are perpendicular to the vertical cross-shaped surface of the cross component 55. The rotation points of the upper and lower blocks 56 and the left and right blocks 57 are located at the center point of the vertical surface along their respective length directions. The cross component 55 is fixedly connected to a shifting electric cylinder 58 corresponding to the two upper and lower blocks 56 and the two left and right blocks 57, so that the upper and lower blocks 56 and the left and right blocks 57 can rotate within a range of 180 degrees, and the upper and lower blocks 56 and the left and right blocks 57 are horizontal after each rotation. Each grouting drilling machine 5 is slidably connected to one end of the corresponding upper and lower blocks 56 along the length direction, and each grouting drilling machine 51 is slidably connected to one end of the corresponding left and right blocks 57 along the length direction. Both the grouting drilling machine 5 and the grouting drilling machine 51 move along the rotation axis of the upper and lower blocks 56.

[0053] Reference Figure 1A push cylinder 59 is fixedly connected to the cross-shaped vertical surface of the cross-shaped component 55 away from the upper and lower blocks 56. The power rod of the push cylinder 59 is fixed to the synchronizing component 41. The synchronizing component 41 is also cross-shaped corresponding to the cross-shaped component 55. The upper and lower ends of the synchronizing component 41 are fixedly connected to the upper and lower push rods 42. The horizontal ends of the synchronizing component 41 are detachably connected to the left and right push rods 43. The left and right push rods 43 can be pulled out from the synchronizing component 41 along their own length direction. The upper and lower push rods 42 and the left and right push rods 43 are all inserted and slidably connected to the cross-shaped component 55. The moving direction of the upper and lower push rods 42 and the left and right push rods 43 is consistent with the rotation axis direction of the upper and lower blocks 56.

[0054] Reference Figure 2 and Figure 3 Both the grouting drilling machine 5 and the grouting drilling machine 51 have side blocks 32 fixedly connected to their sides. The upper and lower push rods 42 and the left and right push rods 43 are all inserted into a side block 32. Each side block 32 has a sliding insertion post 33. A hemisphere 24 is fixedly connected to one end of the insertion post 33 near the upper and lower push rods 42 or the left and right push rods 43. The hemisphere 24 and the insertion post 33 can be inserted into the corresponding upper and lower push rods 42 or the left and right push rods 43, so that the upper and lower push rods 42 can drive the grouting drilling machine 5 to move and the left and right push rods 43 can drive the grouting drilling machine 51 to move.

[0055] Reference Figure 3 An inner inclined wedge 35 is fixedly connected to the end of the insertion post 33 away from the hemisphere 24. An internal spring 34 is fixedly connected inside the side block 32 to force the inner inclined wedge 35 to move toward the insertion post 33. Outer inclined wedges 36 are fixedly connected to all four ends of the cross member 55. When the upper and lower push rods 42 and the left and right push rods 43 are inserted into the side block 32, each outer inclined wedge 36 is also inserted into a corresponding side block 32 and the inclined surface of the outer inclined wedge 36 abuts against the inner inclined wedge 35. The inclined surface is such that the outer inclined wedge 36 is located below the insertion post 33, preventing the outer inclined wedge 36 and the insertion post 33 from touching. This also causes the inner inclined wedge 35 to move towards the inner spring 34, so that the insertion post 33 is no longer located within the upper / lower push rod 42 or the left / right push rod 43. Only the hemisphere 24 is located within the upper / lower push rod 42 or the left / right push rod 43, allowing the upper / lower push rod 42 and the left / right push rod 43 to easily detach from the side block 32. When the side block 32 abuts against the cross member 55, the vertical sides of the inner inclined wedge 35 and the outer inclined wedge 36, perpendicular to the axis of the insertion post 33, abut against each other, making it difficult for the side block 32 to move further. This ensures that even after the upper / lower push rod 42 or the left / right push rod 43 detaches from the corresponding side block 32, the grouting drilling machine 5 and the grouting drilling machine 51 can maintain stable positions.

[0056] Reference Figure 4 and Figure 5Each upper and lower block 56 is provided with a grouting insertion device 52 at the end away from the grouting drilling machine 5. The grouting insertion device 52 includes a grouting slide tube 44 located on the side of the upper and lower block 56 away from the grouting drilling machine 5. The grouting slide tube 44 includes a moving tube 39 slidably connected to the upper and lower block 56 along the rotation axis of the upper and lower block 56. A side block 32 is also fixedly provided at the end of the moving tube 39 near the upper and lower push rods 42 so that the movement of the upper and lower push rods 42 can drive the moving tube 39 to move synchronously. The moving tube 39 can be connected to the grouting pump 54 (not shown in the figure) through a hose. At the end of the transfer tube 39 away from the cross member 55, a coaxial fixed connection and a connecting tube 38 are provided. The outer diameter of the connecting tube 38 is smaller than that of the transfer tube 39. The connecting tube 38 is coaxially inserted and sealed and slidably connected to a sleeve 37. A threaded tube 45 is coaxially rotatably connected to the outer circumference of the sleeve 37. The end of the threaded tube 45 away from the sleeve 37 is threaded to the inner circumference of the grouting pipe 1. Two guide rods 46 are fixedly connected to the outer circumference of the sleeve 37 near the transfer tube 39. The guide rods 46 are inserted into the end face of the grouting pipe 1 along the axial direction of the sleeve 37, so that the grouting pipe 1 will not rotate synchronously with the threaded tube 45 when the threaded tube 45 rotates. A tube gear 23 is coaxially fixedly connected to one end of the threaded tube 45 near the moving tube 39. A threaded tube motor 47 is fixedly connected to the outer circumference of one end of the sleeve 37 where the guide rod 46 is provided. A motor gear 25 meshing with the tube gear 23 is coaxially fixedly connected to the output shaft of the threaded tube motor 47, so that the threaded tube 45 can be driven to rotate, so that the threaded tube 45 can be connected to or disconnected from the grouting pipe 1.

[0057] Reference Figure 5 Several sleeve springs 21 are evenly arranged around the axis of the insertion tube 38 between the end faces of the sleeve 37 and the transfer tube 39. The two ends of the sleeve springs 21 are hooked to the end faces of the sleeve 37 and the transfer tube 39 respectively. A tube ring 22 located between the sleeve 37 and the transfer tube 39 is coaxially fixedly connected to the outer circumference of the insertion tube 38. The tube ring 22 can abut against the end face of the sleeve 37 facing the transfer tube 39. After the grouting is completed, the upper and lower push rods 42 first drive the transfer tube 39 away from the sleeve 37 by a suitable distance, so that the tube ring 22 no longer abuts against the end face of the sleeve 37. Then the threaded tube motor 47 is connected to the external power supply so that the threaded tube 45 rotates to disengage from the grouting tube 1. When the threaded tube 45 disengages from the grouting tube 1, the sleeve springs 21 will pull the sleeve 37 to abut against the tube ring 22 again. Then the upper and lower push rods 42 can continue to move away from the grouting tube 1.

[0058] Reference Figure 4 and Figure 6Each left and right block 57 has a grouting insertion device 53 at one end away from the grouting drilling machine 51. The grouting insertion device 53 includes a grouting slide tube 48 slidably connected to the left and right blocks 57 along the rotation axis of the left and right blocks 57. The side of the grouting slide tube 48 is also fixedly connected to a side block 32 for the left and right push rods 43 to insert into, so that the movement of the left and right push rods 43 can drive the grouting slide tube 48 to move synchronously. An insertion rod 49 is fixedly connected to the end face of the grouting slide tube 48 away from the left and right push rods 43. The insertion rod 49 is inserted into the grouting pipe 2 so that the grouting pipe 2 is pushed into the wall by the grouting slide tube 48. The end face of the grouting slide tube 48 that abuts against the grouting pipe 2 has a pipe port 31. The pipe port 31 penetrates the outer and inner walls of the grouting slide tube 48 so that the grout from the grouting pipe 2 can flow out from the pipe port 31 in a timely manner.

[0059] The implementation principle of a drilling and grouting device according to an embodiment of this application is as follows: the electric cylinder 59 drives the synchronizing element 41, two upper and lower push rods 42 and two left and right push rods 43 to move toward the wall, so that the two grouting drilling machines 5 and the two grouting drilling machines 51 move toward the wall to form grouting holes and grouting holes. After drilling is completed, the upper and lower push rods 42 and the left and right push rods 43 are reset and disengaged from the side block 32. Then, the shifting electric cylinder 58 drives the left and right blocks 57 and the upper and lower blocks 56 to rotate, so that the pre-set grouting pipe 1 corresponds to the grouting hole and the grout outlet pipe 2 corresponds to the grout outlet hole. Then, the upper and lower push rods 42 and the left and right push rods 43 move towards the wall again, so that the grouting pipe 1 and the grout outlet pipe 2 are inserted into the wall. Then, the grouting pump 54 starts grouting until grout flows out of the pipe port 31. Then, the upper and lower push rods 42 and the left and right push rods 43 move away from the wall a short distance, and then the threaded pipe motor 47 drives the threaded pipe 45 to rotate until the threaded pipe 45 disengages from the grouting pipe 1 and abuts against the pipe ring 22. Then, the upper and lower push rods 42 and the left and right push rods 43 continue to move away from the wall, so that the upper and lower push rods 42 and the left and right push rods 43 are completely disengaged from the side block 32.

[0060] Then the base 3 moves to form and grout the next two grouting holes. Since only one grout outlet is set between the two rows of grouting holes, only one grout outlet needs to be formed when forming the second row of grouting holes, except when forming the first row of grouting holes. Therefore, only one left and right push rod 43 needs to be set when forming the second row of grouting holes.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
