DETAILED DESCRIPTION

[0028] In order to enable personnel in the technical field to better understand the present application scheme, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination 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 the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0029] The embodiments of the present application provide a lateral pressure expansion mechanism for construction hole body treatment, a drill pipe and a drilling equipment, which can solve the problem in the prior art that the collapsible loess compaction pile hole pipe can reduce the collapsible loess compaction pile, which is punched into the hole after the hole construction is completed, and the circumferential soil is difficult to follow the construction drilling machine to advance synchronously, which affects the construction progress and reduces the construction efficiency.

[0030] As shown in Figure 1 , Figure 3 , Figure 4 and Figure 5 , in one aspect, the present application provides a lateral pressure expansion mechanism for construction hole body treatment, which comprises:

[0031] The upper connecting end 1 and the lower connecting end 2 are arranged at intervals, the upper connecting end 1 is used for connecting with the sleeve rod 3, and the lower connecting end 2 is used for connecting with the shell of the mechanical drill bit 4;

[0032] The linkage drill pipe 5 passes through the upper connecting end 1 and the lower connecting end 2, one end of the linkage drill pipe 5 is used for connecting with the drill pipe driving part, and the other end is used for connecting with the drill bit rotating part in the shell of the mechanical drill bit 4;

[0033] The 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 the compaction plates 81. 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 such that when the linkage drill rod 5 moves axially with the drill rod drive unit, causing the upper connecting end 1 and the lower connecting end 2 to move closer or further away from each other, the compaction plates 81 are driven to extend or retract radially along the linkage drill rod 5.

[0034] When using the lateral diffuser mechanism for drilling hole treatment, the upper connecting end 1 is connected to the sleeve rod 3, and the lower connecting end 2 is connected to the housing 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 to the drill rod drive unit, and the other end is used to connect to the drill bit rotating part inside the housing of the mechanical drill bit 4. The 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 the compaction plates 81. Both ends of the linkage structure 82 are connected to the upper connecting end 1 and the lower connecting end 2, respectively. The linkage structure 82 is configured such that when the linkage drill rod 5 moves axially with the drill rod drive unit, causing the upper connecting end 1 and the lower connecting end 2 to move closer or further away from each other, the compaction plates 81 are driven to extend or retract radially along 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 housing of the mechanical drill bit 4, when the linkage drill rod 5 moves axially with the drill rod drive unit, causing the upper connecting end 1 and the lower connecting end 2 to move closer to each other, the driving compaction plate 81 extends radially along the linkage 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 for the collapsible loess compaction pile, which can reduce soil fall, is driven into the hole after the hole construction is completed, and the soil in the circumference is squeezed. 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 drive unit can be a rotating disk above the drill rod or a drive drill rod inside the sleeve 3. The mechanical drill bit 4 housing 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 linkage drill rod 5.

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

[0037] In the embodiment, the threaded section 51 is arranged on the linkage drill rod 5, the inner threaded boss 11 is arranged on the inner side of the upper connecting end head 1, and the inner threaded boss 11 is matched with the threaded section 51, so that the upper connecting end head 1 and the lower connecting end head 2 are driven to approach each other by rotating the linkage drill rod 5. The complete process is as follows: when the drilling operation is performed, the threaded section 51 is separated from the inner threaded boss 11; when the compaction operation is performed, the threaded section 51 is connected with the inner threaded boss 11, the linkage drill rod 5 is rotated by the drill rod driving part, and then the upper connecting end head 1 and the lower connecting end head 2 are driven to approach each other, so as to drive the linkage structure 82 to drive the compaction plate 81 to extend, and the structure is simple and stable.

[0038] In the embodiment, the threaded section 51 is arranged on the linkage drill rod 5, the inner threaded boss 11 is arranged on the inner side of the upper connecting end head 1, and the inner threaded boss 11 is matched with the threaded section 51, so that the upper connecting end head 1 and the lower connecting end head 2 are driven to approach each other by rotating the linkage drill rod 5. The complete process is as follows: when the drilling operation is performed, the threaded section 51 is separated from the inner threaded boss 11; when the compaction operation is performed, the threaded section 51 is connected with the inner threaded boss 11, the linkage drill rod 5 is rotated by the drill rod driving part, and then the upper connecting end head 1 and the lower connecting end head 2 are driven to approach each other, so as to drive the linkage structure 82 to drive the compaction plate 81 to extend, and the structure is simple and stable.

[0039] As shown in Figure 1 and Figure 4 In some optional embodiments, the linkage structure 82 includes linkage rod units corresponding to the compaction plates 81, and each linkage rod unit includes two connecting rods 821, one end of each connecting rod 821 is rotationally connected, and the other end of each connecting rod 821 is rotationally connected with the upper connecting end head 1 and the lower connecting end head 2, respectively.

[0040] In the 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, and each linkage rod unit includes two connecting rods 821, one end of each connecting rod 821 is rotationally connected, and the other end of each connecting rod 821 is rotationally connected with the upper connecting end head 1 and the lower connecting end head 2, respectively. In the drilling operation, the included angle of the two connecting rods 821 is opened towards the linkage drill rod 5, and the included angle is greater than 90° and less than 180°.

[0041] As shown in Figure 1 and Figure 4 In some optional embodiments, the middle part of the compaction plate 81 is provided with a connecting plate 811, the connecting plate 811 is provided with a horizontal through hole, and the connecting plate 811 is connected with the connecting rod 821 through the pin shaft passing through the horizontal through hole.

[0042] In the embodiment, the middle part of the compaction plate 81 is provided with a connecting plate 811, the connecting plate 811 is provided with a horizontal through hole, and the connecting plate 811 is connected with the connecting rod 821 through the pin shaft passing through the horizontal through hole. The connection mode is simple and easy to implement.

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

[0044] In this embodiment, a slag baffle plate 812 is provided at the upper end of the compaction plate 81. The slag baffle plate 812 is located above the connecting plate 811, and the width of the slag baffle plate 812 is greater than the width of the connecting plate 811. The slag baffle plate 812 is used to block debris from falling into the connecting plate 811, preventing the connecting plate 811 from getting stuck with the connecting rod 821, which would cause expansion and contraction failure and affect the structural stability of the diffuser assembly 8.

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

[0046] In some alternative embodiments, link 821 is a telescopic rod.

[0047] In this embodiment, the moving distance of the compaction plate 81 can be changed to suit holes of different diameters, thereby improving the applicability of the lateral expansion mechanism used for hole treatment.

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

[0049] In this embodiment, the lateral expansion mechanism for treating the construction hole includes eight compaction plates 81. When the expansion assembly 8 is in a contracted state, any compaction plate 81 partially overlaps with the adjacent compaction plate 81, and there is a gap in the overlapping part, which ensures that it can be completely retracted when contracted and can form a cylinder when extended, which facilitates compaction of the hole wall and improves the compaction effect.

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

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

[0052] In this embodiment, both the upper connecting end 1 and the lower connecting end 2 are connected to the sleeve 3 and the mechanical drill bit 4 via the connecting ring 9, which facilitates installation and disassembly, making the installation and disassembly process simpler and easier to replace.

[0053] like Figure 1 , Figure 3 , Figure 4and Figure 5 As shown, this application also provides a drill pipe that includes the aforementioned lateral diffuser mechanism for drilling hole treatment.

[0054] When using the lateral diffuser mechanism for drilling hole treatment, the upper connecting end 1 is connected to the sleeve rod 3, and the lower connecting end 2 is connected to the housing 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 to the drill rod drive unit, and the other end is used to connect to the drill bit rotating part inside the housing of the mechanical drill bit 4. The 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 the compaction plates 81. Both ends of the linkage structure 82 are connected to the upper connecting end 1 and the lower connecting end 2, respectively. The linkage structure 82 is configured such that when the linkage drill rod 5 moves axially with the drill rod drive unit, causing the upper connecting end 1 and the lower connecting end 2 to move closer or further away from each other, the compaction plates 81 are driven to extend or retract radially along 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 housing of the mechanical drill bit 4, when the linkage drill rod 5 moves axially with the drill rod drive unit, causing the upper connecting end 1 and the lower connecting end 2 to move closer to each other, the driving compaction plate 81 extends radially along the linkage 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 for the collapsible loess compaction pile, which can reduce soil fall, is driven into the hole after the hole construction is completed, and the soil in the circumference is squeezed. 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, this application also provides a drilling device that includes the aforementioned drill rod.

[0056] In use of the lateral pressure-expanding mechanism for construction hole body treatment, the upper connecting end head 1 is connected with the sleeve rod 3, the lower connecting end head 2 is connected with the casing of the mechanical drill bit 4, the linkage drill rod 5 passes through the upper connecting end head 1 and the lower connecting end head 2, one end of the linkage drill rod 5 is used for being connected with the drill rod driving part, the other end is used for being connected with the drill bit rotating part in the casing of the mechanical drill bit 4, the pressure-expanding assembly 8 comprises the linkage structure 82 and a plurality of compacting plates 81 arranged along the circumference of the linkage drill rod 5, the linkage structure 82 is connected with all the compacting plates 81, both ends of the linkage structure 82 are respectively connected with the upper connecting end head 1 and the lower connecting end head 2, and the linkage structure 82 is configured to drive the compacting plates 81 to extend or retract along the radial direction of the linkage drill rod 5 when the linkage drill rod 5 moves along the axial direction with the drill rod driving part to drive the upper connecting end head 1 and the lower connecting end head 2 to approach or move away from each other. Since the upper connecting end head 1 is connected with the sleeve rod 3 and the lower connecting end head 2 is connected with the casing of the mechanical drill bit 4, when the linkage drill rod 5 moves along the axial direction with the drill rod driving part to drive the upper connecting end head 1 and the lower connecting end head 2 to approach each other, the compacting plates 81 extend along the radial direction of the linkage drill rod 5 to compact the hole wall, which can be directly assembled on the drill rod and compact the hole wall during the drilling operation, thereby solving the problem that the existing collapsible loess compaction pile reducing backfill soil is formed after the hole is constructed, and it is difficult to follow the construction drilling machine to advance synchronously, which affects the construction progress and reduces the construction efficiency.

[0057] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the construction process is: S1: before construction, the site is treated first, the original construction ground 6 and the cave throwing filling area 7 are divided, in the cave throwing filling area 7, for single holes with a cave height less than 3m, backfilling clay is used, for single-layer caves with a height of 3-5m or a height less than 3m and a diameter greater than 3m, the throwing filling of stone + clay method is used, repeated pounding and beating are carried out, and the preliminary compaction of the hole wall of the cave is completed; S2: the lateral pressure-expanding mechanism for construction hole body treatment and the drill rod are connected, and the running state is tested; S3: after drilling to the first drilling depth, the expansion construction preparation is started, the first drilling depth can be calculated according to the formula: first drilling depth = total height of the mechanical drill bit 4 + height of the pressure-expanding assembly 8; S4: when the drill rod driving part is lifted to the threaded section 51 and the internal thread boss 11 are connected, the linkage drill rod 5 is rotated by the drill rod driving part, and then the upper connecting end head 1 and the lower connecting end head 2 are driven to approach each other to drive the linkage structure 82 to drive the compacting plates 81 to extend; S5: after compaction, the linkage drill rod 5 is reversed to retract the pressure-expanding assembly 8 in the reverse steps, and the retraction is stopped when the total height of the pressure-expanding assembly 8 is less than the existing drilling hole diameter of about 30cm; continue to drill, and the total height of the pressure-expanding assembly 8 is used as the single drilling construction section height, and S4 and S5 are repeated until the construction reaches the design elevation of the pile bottom.
