[0002] When drilling for pile foundation construction on karst landforms, from the perspective of economy, construction rationality and convenience, the conventional method for drilling for pile foundation construction is to backfill clay for single holes with a cave height of less than 3m, and repeatedly punch and pound the cave wall to make it dense. For single-layer caves with a height of 3-5m or a height of less than 3m and a cavity diameter greater than 3m, the method of throwing and filling with stone flakes + clay is often used, and the cave wall is repeatedly punched and pounded to make it dense, so as to ensure the quality of the hole formed during pile foundation construction.

The loess compaction pile bored pile pipe that can reduce the collapsible soil falling back, by providing an extrusion mechanism and a rotation drive mechanism, can drive the operating disk to rotate through the rotation of the transmission rod, and at the same time cooperate with the telescopic rod to limit the circumferential position of the extrusion plate so that the extrusion plate expands outward, squeezes the soil on the inner wall of the pile hole, and controls the rotation of the rotation drive mechanism through the cooperation of the driving rod and the matching groove, thereby completely compacting the soil on the inner wall of the pile hole, thereby effectively preventing the loess on the inner wall of the pile hole from collapsing.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] The embodiment of the present application provides a lateral pressure expansion mechanism, a drill rod and a drilling equipment for construction hole body treatment, which can solve the problem in the prior art that the loess compaction pile bored pile pipe that can reduce the collapsible soil fall is driven into the hole after the hole construction is completed, and the circumferential soil is squeezed, which is difficult to be synchronously advanced with the construction drilling machinery, thus affecting the construction progress and reducing the construction efficiency.

[0030] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, on the one hand, the present application provides a lateral pressure diffusion mechanism for construction hole body processing, which includes:

[0031] An upper connecting end 1 and a lower connecting end 2 are arranged at intervals, the upper connecting end 1 is used to connect with a sleeve rod 3, and the lower connecting end 2 is used to connect with a housing of a mechanical drill bit 4;

[0032] A linkage drill rod 5 passes through the upper connection end 1 and the lower connection end 2, one end of the linkage drill rod 5 is used to connect with the drill rod driving part, and the other end is used to connect with the drill bit rotating part in the housing of the mechanical drill bit 4;

[0033] The pressure diffuser assembly 8 includes a linkage structure 82 and a plurality of compaction plates 81 arranged circumferentially along the linkage drill rod 5. The linkage structure 82 is connected to all compaction plates 81. Both ends of the linkage structure 82 are respectively connected to the upper connecting end 1 and the lower connecting end 2. The linkage structure 82 is configured as follows: when the linkage drill rod 5 moves along the axial direction with the drill rod driving part, driving the upper connecting end 1 and the lower connecting end 2 to approach or move away from each other, the compaction plate 81 is driven to extend or retract along the radial direction of the linkage drill rod 5.

[0034] When using the lateral pressure diffusion mechanism for construction hole body processing, the upper connecting end 1 is connected to the sleeve rod 3, the lower connecting end 2 is connected to the shell of the mechanical drill bit 4, the linkage drill rod 5 passes through the upper connecting end 1 and the lower connecting end 2, one end of the linkage drill rod 5 is used to connect with the drill rod driving part, and the other end is used to connect with the drill bit rotating part in the shell of the mechanical drill bit 4. The pressure diffusion assembly 8 includes a linkage structure 82 and a plurality of compaction plates 81 arranged circumferentially along the linkage drill rod 5. The linkage structure 82 is connected to all the compaction plates 81, and the two ends of the linkage structure 82 are respectively connected to the upper connecting end 1 and the lower connecting end 2. The linkage structure 82 is configured as follows: when the linkage drill rod 5 moves along the axial direction with the drill rod driving part, driving the upper connecting end 1 and the lower connecting end 2 to approach or move away from each other, the compaction plate 81 is driven to extend or retract along the radial direction of the linkage drill rod 5. Since the upper connecting end 1 is connected to the sleeve rod 3, and the lower connecting end 2 is connected to the shell of the mechanical drill bit 4, when the linked drill rod 5 moves along the axial direction with the drill rod driving part, driving the upper connecting end 1 and the lower connecting end 2 to approach each other, the compacting plate 81 is driven to extend along the radial direction of the linked drill rod 5 to compact the hole wall. It can be directly assembled on the drill rod, and the hole wall can be compacted during the drilling operation. This solves the problem in the prior art that the pile pipe of the loess compaction pile that can reduce the collapsible loess falling soil is driven into the hole after the hole construction is completed to squeeze the circumferential soil, and it is difficult to advance synchronously with the construction drilling machinery, which affects the construction progress and reduces the construction efficiency.

[0035] In this example, the drill rod driving part can be a rotating disk above the drill rod, or a driving drill rod in the casing rod 3. The housing of the mechanical drill bit 4 is rotatably connected to the drill bit rotating part, and the housing and the drill bit rotating part move synchronously when moving along the axial direction of the linked drill rod 5.

[0036] like Figure 1 and Figure 4 As shown, in some optional embodiments, a threaded section 51 is provided on the linkage drill rod 5, and an internal threaded boss 11 is provided on the inner side of the upper connecting end 1. The inner side of the internal threaded boss 11 cooperates with the threaded section 51 to drive the upper connecting end 1 and the lower connecting end 2 to approach each other by rotating the linkage drill rod 5.

[0037] In this embodiment, a threaded section 51 is provided on the linkage drill rod 5, and an internal threaded boss 11 is provided on the inner side of the upper connecting end head 1. The inner side of the internal threaded boss 11 cooperates with the threaded section 51, and is used to drive the upper connecting end head 1 and the lower connecting end head 2 to approach each other by rotating the linkage drill rod 5. The complete process is: when in drilling operation, the threaded section 51 is separated from the internal threaded boss 11, and when in compaction operation, the drill rod driving part is lifted until the threaded section 51 is connected to the internal threaded boss 11, and the linkage drill rod 5 is driven to rotate through the drill rod driving part, thereby driving the upper connecting end head 1 and the lower connecting end head 2 to approach each other, so as to drive the linkage structure 82 to drive the compaction plate 81 to extend. The structure is simple and the stability is good.

[0038] In this example, the sleeve rod 3 and the mechanical drill bit 4 can also be set to a rotating state. At this time, the threaded section 51 can always be located on the inner side of the internal threaded boss 11. When in drilling operation, the upper connecting end 1 and the linked drill rod 5 rotate synchronously. When in compaction operation, the sleeve rod 3 and the mechanical drill bit 4 stop rotating, and the linked drill rod 5 rotates in the opposite direction, driving the upper connecting end 1 and the lower connecting end 2 to approach each other.

[0039] like Figure 1 and Figure 4 As shown, in some optional embodiments, the linkage structure 82 includes a linkage rod unit corresponding one to one with the compaction plate 81, and the linkage rod unit includes two connecting rods 821, one end of the two connecting rods 821 is rotatably connected and rotatably connected to the middle part of the corresponding compaction plate 81, and the other end is rotatably connected to the upper connecting terminal 1 and the lower connecting terminal 2 respectively.

[0040] In this embodiment, the structure of the linkage structure 82 is specifically described. The linkage structure 82 includes linkage rod units corresponding to the compaction plates 81 one by one. The linkage rod units include two connecting rods 821. One end of the two connecting rods 821 is rotatably connected and rotatably connected to the middle part of the corresponding compaction plate 81. The other ends of the two connecting rods 821 are rotatably connected to the upper connecting end 1 and the lower connecting end 2 respectively. During the drilling operation, the angle between the two connecting rods 821 opens toward the linkage drill rod 5, and the angle is greater than 90° and less than 180°.

[0041] like Figure 1 and Figure 4 As shown, in some optional embodiments, a connecting plate 811 is provided in the middle of the compacting plate 81, a horizontal through hole is provided on the connecting plate 811, and the connecting plate 811 is connected to the connecting rod 821 via a pin passing through the horizontal through hole.

[0042] In this embodiment, a connecting plate 811 is provided in the middle of the compacting plate 81. The connecting plate 811 is provided with a horizontal through hole. The connecting plate 811 and the connecting rod 821 are connected by a pin shaft passing through the horizontal through hole. The connection method is simple and easy to implement.

[0043] like Figure 1 and Figure 4 As shown, in some optional embodiments, a slag blocking plate 812 is provided at the upper end of the compaction plate 81 , the slag blocking plate 812 is located above the connecting plate 811 , and the width of the slag blocking plate 812 is greater than the width of the connecting plate 811 .

[0044] In this embodiment, a slag stop plate 812 is provided at the upper end of the compaction plate 81. The slag stop plate 812 is located above the connecting plate 811, and the width of the slag stop plate 812 is greater than the width of the connecting plate 811. The slag stop plate 812 is used to prevent debris from falling into the connecting plate 811, to prevent the connecting plate 811 and the connecting rod 821 from getting stuck, resulting in telescopic failure, and affecting the structural stability of the diffuser assembly 8.

[0045] In this example, the slag blocking plate 812 is tilted downward. The width of the slag blocking plate 812 is set according to the width of the connecting plate 811 + 2 cm.

[0046] In some optional embodiments, the connecting rod 821 is a telescopic rod.

[0047] In this embodiment, the moving distance of the compacting plate 81 can be changed to be suitable for holes of different diameters, thereby improving the applicability of the lateral pressure diffusion mechanism for hole body treatment.

[0048] like Figure 3 As shown, in some optional embodiments, eight compaction plates 81 are included. When the diffuser assembly 8 is in a contracted state, any compaction plate 81 partially overlaps with an adjacent compaction plate 81 , and a gap exists in the overlapping portion.

[0049] In this embodiment, the lateral diffusion mechanism for construction hole body treatment includes eight compaction plates 81. When the diffusion assembly 8 is in a retracted state, any compaction plate 81 partially overlaps with an adjacent compaction plate 81, and there is a gap in the overlapping portion, ensuring that it can be completely retracted when contracted and can form a cylinder when extended, which is convenient for compacting the hole wall and improving the compaction effect.

[0050] In this example, a single compaction plate 81 is set with a pre-deflection angle of 1° to 2° according to the center point of the perfect circle.

[0051] like Figure 1 and Figure 4 As shown, in some optional embodiments, the upper connecting end 1 and the lower connecting end 2 are both connected to the sleeve rod 3 and the mechanical drill bit 4 through a connecting ring 9.

[0052] In this embodiment, the upper connecting end 1 and the lower connecting end 2 are connected to the sleeve rod 3 and the mechanical drill bit 4 through the connecting ring 9, which is convenient for installation and disassembly. The installation and disassembly process is simpler and convenient for replacement.

[0053] like Figure 1 , Figure 3 , Figure 4and Figure 5 As shown, on the one hand, the present application also provides a drill rod, which includes the above-mentioned lateral pressure expansion mechanism for construction hole body processing.

[0054] When using the lateral pressure diffusion mechanism for construction hole body processing, the upper connecting end 1 is connected to the sleeve rod 3, the lower connecting end 2 is connected to the shell of the mechanical drill bit 4, the linkage drill rod 5 passes through the upper connecting end 1 and the lower connecting end 2, one end of the linkage drill rod 5 is used to connect with the drill rod driving part, and the other end is used to connect with the drill bit rotating part in the shell of the mechanical drill bit 4. The pressure diffusion assembly 8 includes a linkage structure 82 and a plurality of compaction plates 81 arranged circumferentially along the linkage drill rod 5. The linkage structure 82 is connected to all the compaction plates 81, and the two ends of the linkage structure 82 are respectively connected to the upper connecting end 1 and the lower connecting end 2. The linkage structure 82 is configured as follows: when the linkage drill rod 5 moves along the axial direction with the drill rod driving part, driving the upper connecting end 1 and the lower connecting end 2 to approach or move away from each other, the compaction plate 81 is driven to extend or retract along the radial direction of the linkage drill rod 5. Since the upper connecting end 1 is connected to the sleeve rod 3, and the lower connecting end 2 is connected to the shell of the mechanical drill bit 4, when the linked drill rod 5 moves along the axial direction with the drill rod driving part, driving the upper connecting end 1 and the lower connecting end 2 to approach each other, the compacting plate 81 is driven to extend along the radial direction of the linked drill rod 5 to compact the hole wall. It can be directly assembled on the drill rod, and the hole wall can be compacted during the drilling operation. This solves the problem in the prior art that the pile pipe of the loess compaction pile that can reduce the collapsible loess falling soil is driven into the hole after the hole construction is completed to squeeze the circumferential soil, and it is difficult to advance synchronously with the construction drilling machinery, which affects the construction progress and reduces the construction efficiency.

[0055] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, on the other hand, the present application also provides a drilling device, which includes the above-mentioned drill rod.

[0056] When using the lateral pressure diffusion mechanism for construction hole body processing, the upper connecting end 1 is connected to the sleeve rod 3, the lower connecting end 2 is connected to the shell of the mechanical drill bit 4, the linkage drill rod 5 passes through the upper connecting end 1 and the lower connecting end 2, one end of the linkage drill rod 5 is used to connect with the drill rod driving part, and the other end is used to connect with the drill bit rotating part in the shell of the mechanical drill bit 4. The pressure diffusion assembly 8 includes a linkage structure 82 and a plurality of compaction plates 81 arranged circumferentially along the linkage drill rod 5. The linkage structure 82 is connected to all the compaction plates 81, and the two ends of the linkage structure 82 are respectively connected to the upper connecting end 1 and the lower connecting end 2. The linkage structure 82 is configured as follows: when the linkage drill rod 5 moves along the axial direction with the drill rod driving part, driving the upper connecting end 1 and the lower connecting end 2 to approach or move away from each other, the compaction plate 81 is driven to extend or retract along the radial direction of the linkage drill rod 5. Since the upper connecting end 1 is connected to the sleeve rod 3, and the lower connecting end 2 is connected to the shell of the mechanical drill bit 4, when the linked drill rod 5 moves along the axial direction with the drill rod driving part, driving the upper connecting end 1 and the lower connecting end 2 to approach each other, the compacting plate 81 is driven to extend along the radial direction of the linked drill rod 5 to compact the hole wall. It can be directly assembled on the drill rod, and the hole wall can be compacted during the drilling operation. This solves the problem in the prior art that the pile pipe of the loess compaction pile that can reduce the collapsible loess falling soil is driven into the hole after the hole construction is completed to squeeze the circumferential soil, and it is difficult to advance synchronously with the construction drilling machinery, which affects the construction progress and reduces the construction efficiency.

[0057] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the construction process is as follows: S1: before construction, the site is treated first, and the original construction ground 6 and the cave dumping area 7 are divided. In the cave dumping area 7, for a single cave with a cave height less than 3m, clay is backfilled. For a single-layer cave with a height of 3-5m or a height less than 3m and a cavity diameter greater than 3m, a stone dumping + clay method is used, and repeated impact is performed to complete the initial compaction of the cave wall; S2: The lateral expansion mechanism and the drill rod used for construction hole body treatment are connected to test the operating status; S3: After drilling to the first drilling depth, the expansion construction preparation begins. The first drilling depth can be calculated according to the following formula: First drilling depth = machine The total height of the mechanical drill bit 4 + the height of the pressure diffuser assembly 8; S4: when the drill rod driving part is lifted up until the threaded section 51 is docked with the internal threaded boss 11, the linkage drill rod 5 is driven to rotate through the drill rod driving part, thereby driving the upper connecting end 1 and the lower connecting end 2 to approach each other, so as to drive the linkage structure 82 to drive the compaction plate 81 to extend; S5: after compaction, the linkage drill rod 5 is reversed, and the pressure diffuser assembly 8 is retracted in the opposite steps, and the contraction can be stopped when it is contracted to about 30 cm less than the existing borehole diameter; continue drilling, with the overall height of the pressure diffuser assembly 8 as the single drilling construction segment height, repeat S4 and S5 until the construction reaches the designed elevation of the pile bottom.
