Description

Technical Field

[0001] The present application relates to the technical field of prefabricated buildings, and in particular to a prefabricated component grouting connection node and a construction process thereof. Background Art

[0002] At present, in the process of construction of prefabricated components such as prefabricated walls, grouting is often used for installation, that is, steel bars extending upward from the construction foundation surface are pre-embedded in the lower component, and a grouting sleeve is pre-embedded at the bottom of the upper component to be installed. After the installation of the lower component is completed, when installing the upper component, the upper component is hoisted and moved to the grouting sleeve, and the steel bars of the lower component are downwardly sleeved, and then grouting is performed in the grouting sleeve. After the slurry solidifies, the connection between the upper component and the lower component is completed.

[0003] Among them, when grouting the grouting sleeve, a grouting machine is usually used to deliver grout to the grouting hole located on the lower side of the grouting sleeve. After the grout overflows from the grouting hole located on the upper side of the grouting sleeve, a rubber plug is used to seal the grouting hole and the grouting hole. This method is prone to incomplete grouting, making it difficult to control the connection quality between the steel bar and the grouting sleeve. Summary of the invention

In addition, in the process of the upper component moving downward in the grouting area, downward pressure can be applied to the slurry to assist the slurry in filling the sleeve.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1 To Attachment Fig.14 This application is described in further detail.

[0028] Embodiment 1:

[0029] The present application embodiment discloses a prefabricated component grouting connection node. Figure 1 and Figure 2 The prefabricated component grouting connection node includes an upper component 1, a lower component 2, an end stopper 6 and a side stopper 7.

[0030] Reference Figure 1 and Figure 3 The upper member 1 includes an upper member body 101 and upper longitudinal ribs 102, the upper longitudinal ribs 102 are embedded in the upper member body 101 and extend in the longitudinal direction, and a plurality of upper longitudinal ribs 102 are distributed in an array, the bottom of the upper longitudinal ribs 102 extend downward out of the upper member body 101, and the bottom of the upper longitudinal ribs 102 extend downward out of the bottom surface of the upper member 1. In this embodiment, the upper member body 101 is a square wall, and the upper longitudinal ribs 102 are steel bars.

[0031] The lower member 2 includes a lower member body 201, a sleeve 202 and a lower longitudinal rib 203. The sleeve 202 is in a hollow cylindrical shape and is embedded in the top of the lower member body 201. The top surface of the sleeve 202, the top surface of the lower member body 201 and the construction foundation surface for installing the upper member 1 are all flush, and the inner diameter of the sleeve 202 is greater than the outer diameter of the upper longitudinal rib 102. The lower longitudinal rib 203 is embedded in the lower member body 201 and extends longitudinally. There are multiple lower longitudinal ribs 203 distributed in the lower member 2 in an array. At the same time, the lower longitudinal ribs 203 correspond to the sleeve 202 one by one. The top of the lower longitudinal rib 203 coaxially extends to the bottom of the corresponding sleeve 202 and is fixed to the sleeve 202. The lower member body 201 in this embodiment is a square wall, and the lower longitudinal rib 203 is a steel bar. In other embodiments, the lower member body 201 can also be a floor slab of a transfer layer.

[0032] Reference Figure 1 and Figure 2 The end stopper 6 and the side stopper 7 are both detachably connected to the construction foundation surface, the end stopper 6 is opposite to the end of the upper component body 101, and the side stopper 7 is opposite to the side of the upper component body 101. The end stops 6 at both ends of the upper component body 101 jointly clamp the side stops 7 on both sides to enclose and form a grouting area, and the inner cavity of the sleeve 202 in the lower component 2 is connected to the grouting area.

[0033] When installing the upper member 1, first install the end stopper 6 and the side stopper 7, pour the slurry into the grouting area, and the slurry flows into the sleeve 202 by its own gravity to fill the sleeve 202 and accumulate in the grouting area. After the slurry is poured, the upper member 1 is hoisted to the position opposite to the grouting area and gradually lowered, so that the upper longitudinal ribs 102 gradually extend downward into the corresponding sleeve 202, and the upper longitudinal ribs 102 and the lower longitudinal ribs 203 on the same sleeve 202 are coaxial, and the upper member body 101 is embedded in the grouting area until the height of the upper member body 101 reaches the design elevation, and a leveling gap 4 filled with slurry is formed between the top surface of the upper member body 101 and the top surface of the lower member body 201. After the slurry solidifies to a certain strength, the end stopper 6 and the side stopper 7 can be removed. In this embodiment, the height of the leveling gap 4 is 20 mm.

[0034] Reference Figure 1 and Figure 3In order to allow excess slurry to overflow during the process of lowering and pressing slurry on the upper member 1, an overflow channel 5 is provided on the upper member body 101. Specifically, a plurality of overflow channels 5 are evenly spaced along the length direction of the upper member body 101, and in this embodiment, the interval between two adjacent overflow channels 5 is 500 mm. Each overflow channel 5 includes a transverse slurry guide groove 51 and a longitudinal slurry guide groove 52. The transverse slurry guide groove 51 horizontally penetrates the opposite sides of the upper member body 101 along the thickness direction of the upper member body 101, and the longitudinal slurry guide groove 52 vertically penetrates the middle of the transverse slurry guide groove 51 and the bottom surface of the upper member body 101. During the process of pressing slurry on the upper member 1, excess slurry enters the upper member body 101 from the longitudinal slurry guide groove 52 and overflows from the transverse slurry guide groove 51 to the outside of the upper member body 101.

[0035] Reference Figure 1 , Figure 2 and Figure 4 Specifically, the end stopper 6 is in the shape of a square strip and can be detached from the construction foundation surface through ground nails. The side stopper 7 includes a positioning seat 72 and a stopper set 71. The positioning seat 72 is detachably connected to the construction foundation surface through ground nails, and multiple positioning seats 72 are provided on each side of the upper component body 101 along the length direction of the upper component body 101. The stopper set 71 is detachably connected to the side of the positioning seat 72 facing the grouting area, and the side stopper 7 encloses the grouting area through the stopper set 71.

[0036] Reference Figure 4 and Figure 5 , the retaining edge group 71 includes a first retaining edge 711, a second retaining edge 712 and a third retaining edge 713. The first retaining edge 711 is in the shape of a rectangular strip, and the extension height of the first retaining edge 711 is greater than the extension height of the leveling gap 4. The second retaining edge 712 is located above the first retaining edge 711 and is connected to the first retaining edge 711 through the adjustment component 8. The second retaining edge 712 is located directly above the first retaining edge 711 and is in the shape of a rectangular strip. An extension portion 18 is fixed to the top of the second retaining edge 712 on the side away from the grouting area. The third retaining edge 713 is in the shape of a rectangular strip, and one side of the third retaining edge 713 is hinged to the side of the second baffle away from the grouting area through a hinge shaft. It should be noted that the length extension direction and extension length of the first retaining edge 711, the second retaining edge 712, the extension portion 18 and the third retaining edge 713 are consistent, and the hinge axis of the third retaining edge 713 is parallel to its own length extension direction.

[0037] The connection between the retaining edge group 71 and the positioning seat 72 is that a mounting column 11 extending horizontally and vertically along the length direction of the first retaining edge 711 is fixed to the side surface of one side of the first retaining edge 711, the mounting column 11 has an external thread, the positioning seat 72 is in a square shape and is slidably sleeved on the mounting column 11 along the axis of the mounting column 11, and a nut is threadedly connected to the mounting column 11, and the nut abuts against the side of the positioning seat 72 away from the first retaining edge 711. It should be noted that the bottom surface of the positioning seat 72 is flush with the bottom surface of the first retaining edge 711, and the top surface of the positioning seat 72 is higher than the top surface of the first retaining edge 711.

[0038] In addition, the positioning seat 72 is adjusted to move up and down with a support assembly 9, and the top of the support assembly 9 is against the bottom surface of the third stop edge 713 to support the third stop edge 713. By adjusting the height position of the support assembly 9, the rotation angle of the third stop edge 713 relative to the second stop edge 712 can be adjusted. The third stop edge 713 has a top limit state and a bottom limit state relative to itself.

[0039] Reference Figure 4 When the third stop edge 713 is in the top limit state, the upper edge surface of the third stop abuts against the side edge of the extension portion 18 away from the second stop edge 712, and the extension portion 18 prevents the third stop edge 713 from continuing to rotate upward. At this time, the side of the third stop edge 713 away from the second stop edge 712 is higher than the hinged side of the third stop edge 713.

[0040] Reference Figure 6 , when the third stop edge 713 is at the bottom limit state, the lower surface of the third stop edge 713 abuts against the edge line of the top of the positioning seat 72 away from the first stop edge 711, and the positioning seat 72 prevents the third stop edge 713 from moving further downward. At this time, the side of the third stop edge 713 away from the second stop edge 712 is lower than the hinged side of the third stop edge 713.

[0041] Reference Figure 1 and Figure 4 What's more, the retaining edge group 71 has a first state and a second state under the joint action of the adjustment component 8 and the support component 9. Specifically, when the retaining edge group 71 is in the first state, the bottom surface of the first retaining edge 711 abuts against the construction foundation surface, the bottom surface of the second retaining edge 712 abuts against the top surface of the first retaining edge 711, and the first retaining edge 711 is flush with the side of the second retaining edge 712 away from the positioning seat 72, and the third retaining edge 713 is in the top limit position. At this time, the first retaining edge 711, the second retaining edge 712 and the construction foundation surface jointly enclose a grouting area. Combined with Figure 6 When the retaining edge group 71 is in the second state, the bottom surface of the first retaining edge 711 is still in contact with the construction foundation surface, and the second retaining edge 712 moves upward relative to the first state, so that a gap appears between the first retaining edge 711 and the second retaining edge 712, and at the same time, the third retaining edge 713 is adjusted to the bottom limit position.

[0042] Before the upper component 1 is hoisted, the retaining edge group 71 is first adjusted to the first state, and then the slurry is poured into the grouting area. Then the upper component 1 is hoisted to the design elevation, and the retaining edge group 71 remains in the first state during the hoisting of the upper component 1. After the upper component 1 is hoisted, the first stop is opposite to the leveling gap 4, the second retaining edge 712 is lower than the notch of the transverse slurry guide groove 51, and the top surface of the second retaining edge 712 is flush with the lowest point of the notch of the slurry guide groove. At the same time, the side of the third retaining edge 713 away from the second retaining edge 712 is higher than the top of the notch of the transverse slurry guide groove 51. The top surface of the second retaining edge 712, the outer side surface of the upper component body 101 and the second retaining edge 712 together enclose a storage cavity 12 with an upward opening, and the slurry overflowing from the notch of the transverse slurry guide groove 51 is accumulated in the storage cavity 12.

[0043] After the upper component 1 is hoisted and the slurry overflow is completed, the slurry is filled into the storage chamber 12 so that the slurry in the storage chamber 12 is higher than the slot of the transverse slurry guide groove 51, so that the slurry can automatically flow into and fill the transverse slurry guide groove 51 and the longitudinal slurry guide groove 52. Subsequently, the stop edge group 71 is adjusted to the second state, the first stop edge 711 still maintains the blocking state of the leveling gap 4, and the second stop edge 712 moves upward to block the slot of the transverse slurry guide groove 51, and the third stop edge 713 is tilted downward away from the second stop edge 712 to guide the excess slurry away. The stop edge group 71 maintains the second state until the slurry reaches the demoulding strength and all the end stops 6 and the side stops 7 are removed. It should be noted that when the stop edge group 71 is in the first state or the second state, the two ends of the third stop edge 713 that are away from each other are respectively abutted on the two end stops 6 to prevent the slurry from overflowing from the ends of the third stop edge 713.

[0044] Reference Figure 5 Further, for the adjustment assembly 8, multiple groups of the adjustment assembly 8 are evenly spaced along the length direction of the first stop edge 711. Each group of the adjustment assembly 8 includes an extension seat 81, a threaded member 82 and a locking head 83. The extension seat 81 is fixed at the top position of the first stop edge 711 near the positioning seat 72, and is in a square shape. The threaded member 82 has a threaded section with an axis extending vertically. In this embodiment, the threaded member 82 is a stud fixed to the second stop edge 712 facing the positioning seat 72 through a connecting plate, and the threaded member 82 passes through the extension seat 81 downward. The locking head 83 is nut-shaped and two are provided in each group of the adjustment assembly 8. The two locking heads 83 are both threadedly sleeved on the threaded member 82, and the two locking heads 83 are respectively pressed against the upper and lower sides of the extension seat 81 to position the threaded member 82 relative to the extension seat 81. Even if the first stop edge 711 and the second stop edge 712 are relatively positioned, the position of the second stop edge 712 relative to the first stop edge 711 can be adjusted by adjusting the position of the locking head 83.

[0045] More preferably, the threaded member 82 is coaxially fixedly sleeved with a nut-shaped blocking head 19, which is located below the two locking heads 83. When the blocking edge group 71 is in the second state, the blocking head 19 and the extension seat 81 jointly clamp the locking head 83 located at the lower side of the two locking heads 83, and at this time, the distance between the first blocking edge 711 and the second blocking edge 712 is the largest.

[0046] Reference Figure 5 and Figure 7 , for the support assembly 9, the support assembly 9 corresponds to the positioning seat 72 one by one. Each support group includes a support column 91, a rotating column 92, a first bevel gear 93 and a second bevel gear 94. The support column 91 is cylindrical and slides vertically in the positioning seat 72, and the top of the support column 91 extends upward from the positioning seat 72. A block-shaped guide portion 13 is fixed to the bottom of the outer peripheral wall of the support column 91, and a guide groove for the guide portion 13 to slide up and down is provided in the positioning seat 72 to limit the rotation of the support column 91 in the positioning seat 72. The rotating column 92 is cylindrical and rotates in the positioning seat 72, and the axial direction of the rotating column 92 is perpendicular to the axis of the support column 91. One end of the rotating column 92 extends out of the positioning seat 72 and is fixed with a handle. The first bevel gear 93 is rotatably connected to the positioning seat 72, and at the same time, the support column 91 is coaxially threaded through the first bevel gear 93. The second bevel gear 94 is coaxially fixedly sleeved on the rotating column 92, and rotates together with the rotating column 92. At the same time, the first bevel gear 93 is meshed with the second bevel gear 94. Therefore, by rotating the rotating column 92, the second bevel gear 94 is linked with the first bevel gear 93 to rotate, thereby driving the support column 91 to move up and down for adjustment.

[0047] The present application also discloses a construction process for grouting connection nodes of assembled components, comprising the following steps: Step 1: The upper component 1, the lower component 2, the end stopper 6 and the side stopper 7 are manufactured respectively, and the construction of the lower component 2 is completed and the top surface is flush with the construction foundation surface.

[0048] Step 2: Install the end stopper 6 and the side stopper 7 on the construction foundation surface. The inner side surface of the end stopper 6, the inner side surface of the side stopper 7 and the top surface of the lower component body 201 jointly enclose a grouting area; then, adjust the stop edge group 71 to the first state.

[0049] Step 3: Pour slurry into the grouting area. The slurry flows into the sleeve 202 due to its own gravity and gradually accumulates in the grouting area. The upper surface of the slurry in the grouting area is higher than the designed elevation of the bottom surface of the upper component body 101.

[0050] Step 4: Hoist the upper component 1. First, lift the upper component 1 above the grouting area and then gradually lower it so that the upper longitudinal ribs 102 extend vertically into the corresponding sleeves 202. The bottom of the upper component body 101 gradually embeds vertically into the grouting area until it reaches the designed elevation. During the process, the retaining edge group 71 maintains the first state. In the process of pressing the slurry downward on the upper component body 101, excess slurry flows into the storage chamber 12 through the overflow channel 5 for accumulation.

[0051] Step 5: Pour the slurry into the storage chamber 12 so that the upper surface of the slurry is higher than the highest point of the transverse slurry guide groove 51 , so that the slurry automatically flows into the overflow channel 5 and fills the overflow channel 5 .

[0052] Step six: Place a material receiving container opposite to the third baffle 713 on the construction foundation surface, and then adjust the baffle group 71 to move to the second state, so that the slot of the transverse slurry guide groove 51 filled with slurry is blocked by the second baffle 712, and at the same time, the excess slurry is guided by the third baffle 713 to flow downward and be recovered into the material receiving container.

[0053] Step 7: After the slurry hardens to a certain strength, the end stopper 6, the side stopper 7 and the hoisting structure of the upper component 1 are removed, and the slurry surface at the notch of the transverse slurry guide groove 51 close to one end of the upper component body 101 is flush with the outer surface of the upper component body 101.

[0054] Embodiment 2:

[0055] The difference between the embodiment of the present application and the first embodiment is that the side stopper 7 further includes a top edge 20 and a guide rod 21 .

[0056] Specifically, refer to Figure 8 and Fig. 9 The top edge 20 is located directly above the second retaining edge 712, and the top edge 20 is in the shape of a long strip extending along the length direction of the second retaining edge 712. At the same time, the side of the top edge 20 close to the grouting area is flush with the side of the second retaining edge 712 close to the grouting area, and the side of the top edge 20 away from the grouting area exceeds the side of the second retaining edge 712 away from the grouting area in the direction away from the grouting area.

[0057] Reference Fig. 9 and Fig.10The guide rod 21 is rotatably connected to the top edge 20, and there are multiple guide rods 21 spaced apart along the length direction of the top edge 20, and each guide rod 21 is vertically penetrated by a second stop edge 712 and extends into the first stop edge 711. Specifically, the guide rod 21 includes a linkage section 211 and a driving section 212 that are fixedly connected in sequence from top to bottom. The linkage section 211 has linkage teeth 22 evenly spaced apart on its outer circumference, so that any cross section of the linkage section 211 is spline-shaped. The driving section 212 is in the shape of a circular shaft coaxial with the linkage section 211, and the outer diameter of the driving section 212 is smaller than the circumferential size enclosed by the linkage teeth 22, and the outer circumference of the driving section 212 is inclined along its own circumference with a travel groove 24.

[0058] The second stop edge 712 is vertically provided with a through hole for the linkage section 211 to pass through, and the first stop edge 711 is vertically provided with a sliding hole for the driving section 212 to slide, and a travel protrusion (not shown in the figure) is fixed on the inner wall of the sliding hole of the first stop edge 711, and the travel protrusion is pressed into the travel groove 24 of the driving section 212, so that when the guide rod 21 rotates relative to the top edge 20, it can move upward or downward at the same time through the cooperation guidance of the travel protrusion and the travel groove 24, thereby driving the top edge 20 to move upward or downward together.

[0059] Reference Figure 8 and Fig. 9 The third stop edge 713 is hinged to the hinge axis of the second stop edge 712 and is fixed to the third stop edge 713 so as to rotate together with the third stop edge 713. A linkage assembly is provided between the hinge axis of the third stop edge 713 and the linkage section 211. When the third stop edge 713 rotates toward the extension portion 18, the linkage assembly drives the guide rod 21 and the top rod to move upward. Similarly, when the third stop edge 713 rotates toward the positioning seat 72, the linkage assembly drives the guide rod 21 and the top edge 20 to move downward, so that when feeding the overflow channel 5, the third stop edge 713 can be shaken to assist the flow of mortar, reduce internal bubbles, and exert pressure on the slurry between the top edge 20 and the second stop edge 712 through the downward pressure of the top edge 20 to squeeze out residual air, so that the slurry can flow into the overflow channel 5 more easily.

[0060] Reference Fig. 9 and Fig.10Specifically, the linkage assembly includes a first gear 25, a second gear 26, a third gear 27, a main bevel gear 28 and a secondary bevel gear 29. The first gear 25 is coaxially fixedly sleeved on the hinge shaft of the third gear edge 713, and the third gear edge 713 has a cavity for giving way to the first gear 25. The second gear 26 and the third gear 27 are both rotatably connected to the second gear edge 712, and the axis of the second gear 26 is parallel to the axis of the hinge shaft, and the second gear 26 is meshed with the first gear 25 at the same time; the axis of the third gear 27 is parallel to the axis of the linkage section 211, and the third gear 27 is meshed with the linkage tooth 22 at the same time. The main bevel gear 28 and the secondary bevel gear 29 are both rotatably connected to the second gear edge 712, and the main bevel gear 28 is coaxially fixed to the second gear 26 through a rod, and the secondary bevel gear 29 is coaxially fixed to the third gear 27 through a rod. In order to facilitate the assembly of the linkage assembly and the guide rod 21, the first gear edge 711 and the second gear edge 712 are both spliced.

[0061] When the third gear edge 713 swings relative to the second gear edge 712, the third gear edge 713 drives the first gear 25 to rotate synchronously, thereby sequentially linking the second gear 26, the main bevel gear 28, the secondary bevel gear 29, the third gear 27 and the linkage section 211 to rotate, thereby driving the top edge 20 to move vertically.

[0062] Reference Figure 8 and Fig.10 In order to prevent the slurry from leaking from the perforation to between the second retaining edge 712 and the first retaining edge 711, a corrugated sleeve 23 corresponding to the guide rod 21 is connected between the top surface of the second retaining edge 712 and the top edge 20, and the corrugated sleeve 23 encloses the linkage section 211 of the corresponding guide rod 21 between the second retaining edge 712 and the top edge 20. The lower surface of the top edge 20 has a receiving cavity for receiving the compressed corrugated sleeve 23.

[0063] Reference Figure 8 and Fig.10 When the retaining edge group 71 is in the first state, the bottom surface of the top edge 20 is higher than the notch of the transverse slurry guiding groove 51 .

[0064] Reference Fig. 9 and Fig.11 When the second stop edge 712 moves to cover the notch of the transverse slurry guide groove 51, and the blocking head 19 and the extension seat 81 jointly clamp the locking head 83, and the third stop edge 713 abuts against the extension portion 18, there is a moving space between the bottom surface of the top edge 20 and the top surface of the second stop edge 712, refer to Fig.12 In this state, the third stop edge 713 is swung downward to abut against the positioning seat 72, and the top edge 20 is linked to move downward to abut against the top surface of the second stop edge 712. The corrugated sleeve 23 is compressed and stored in the accommodating cavity, so that the slurry between the top edge 20 and the second stop edge 712 is squeezed out and sent to the third stop edge 713 for output, so as to improve the slurry discharge efficiency.

[0065] Furthermore, the top surface of the top edge 20 is an inclined surface that gradually slopes downward away from the grouting area, so as to guide part of the slurry that flows onto or is pressed onto the top surface of the top edge 20 away from the top edge 20 .

[0066] Reference Fig.11 and Fig.12 In addition, a shielding cloth 30 is connected between the extension portion 18 and the third stop edge 713. The shielding cloth 30 extends along the length direction of the third stop edge 713. The shielding cloth 30 is made of a flexible and elastically stretchable material. When the third stop edge 713 abuts against the extension portion 18, the shielding portion is wrinkled. When the third stop edge 713 is in the second state and abuts against the positioning seat 72, the shielding cloth 30 is unfolded. The shielding cloth 30 prevents the slurry from leaking to the hinge axis of the third stop edge 713 when the third stop edge 713 swings.

[0067] The present application also discloses a construction process for grouting connection nodes of assembled components, which is different from the construction process in the first embodiment in that: In step five, pour slurry into the continued accumulation chamber 12 so that the upper surface of the slurry is higher than the highest point of the slot of the transverse slurry guide groove 51, and at the same time, the upper surface of the slurry is close to the bottom surface of the top edge 20, and the support column 91 is adjusted downward for a distance so that the third stop edge 713 can swing between the support column 91 and the extension section to shake the slurry, and at the same time, pressure is applied to the slurry through the top edge 20 to assist the slurry to flow into the overflow channel 5.

[0068] Embodiment three:

[0069] The embodiment of the present application is different from the above-mentioned embodiment in that: a guide cylinder 10 is also included.

[0070] Reference Fig.13 and Fig.14 In this embodiment, the guide cylinder 10 is arranged in the sleeve 202. Specifically, the guide cylinder 10 corresponds to the sleeve 202 one by one and is coaxial with the sleeve 202, and the extension height of the guide cylinder 10 is less than the extension height of the sleeve 202. The guide cylinder 10 includes a connecting ring 14 and a connecting rod 15. There are two connecting rings 14, the two connecting rings 14 are annular and coaxial, and the inner diameter of the connecting ring 14 is greater than the outer diameter of the upper longitudinal rib 102. The connecting rod 15 is fixedly connected between the two connecting rings 14 and is arranged at intervals along the circumference of the connecting ring 14, so that a gap for slurry to flow is formed between two adjacent connecting rods 15, and the extending length direction of the connecting rod 15 is parallel to the axial direction of the connecting ring 14.

[0071] A coaxial reinforcement ring 16 is recessed inwardly on the inner circumference of the sleeve 202, and a connecting block 17 extending inwardly is fixed on the inner wall of the sleeve 202 near the top. When the connecting rod 15 is matched with the guide tube 10, the outer wall of the connecting rod 15 abuts against the inner wall of the reinforcement ring 16, and the connecting block 17 extends between two adjacent connecting rods 15 and is connected to the connecting rod 15. At this time, the connecting block 17 is close to the connecting ring 14 at the lower end of the guide tube 10, and the upper part of the guide tube 10 extends upward from the top of the sleeve 202. It should be noted that the connection between the connecting rod 15 and the connecting block 17 is a weak connection, for example, using a low-strength adhesive or a low-strength material such as plastic or aluminum alloy, so that the connection point between the connecting rod 15 and the connecting block 17 is an easy-to-separate point.

[0072] When pouring slurry into the grouting area, the connecting block 17 remains connected to the connecting rod 15, and the upper surface of the slurry in the grouting area is lower than the upper surface of the guide cylinder 10, and the guide cylinder 10 extends out of the slurry. When the upper component 1 is hoisted, the upper longitudinal ribs 102 are aligned with the guide cylinder 10 to improve the efficiency of reaching the designed position, and during the lowering process of the upper component 1, the upper longitudinal ribs 102 first extend into the guide cylinder 10, and then the bottom surface of the upper component body 101 is against the guide cylinder 10, and the downward pressure of the upper component body 101 makes the connection point between the connecting rod 15 and the connecting block 17 invalid, and the guide cylinder 10 moves downward together under the push of the upper component body 101.

[0073] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
