Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a combined drilling rig coordination device and a method for constructing cast-in-place piles. Background Technology

[0002] In the field of building construction, the following situation exists: In the construction of pile foundations, hole formation is one of the key procedures. With the increasing complexity of building projects, the geological conditions faced by pile foundation construction are becoming increasingly diverse, especially complex strata such as sand and gravel layers, which places higher demands on hole formation technology and equipment.

[0003] Traditional single-layer drilling rigs are ill-suited to varying soil conditions, resulting in low drilling efficiency, prolonged construction periods, and increased project costs. Furthermore, complex geological formations are prone to borehole collapse and shrinkage, severely impacting the quality and safety of the pile foundations.

[0004] Therefore, developing a construction method that can adapt to multiple geological formations and improve drilling efficiency has become an urgent need for the industry. Summary of the Invention

[0005] This application provides a combined drilling rig coordination device and a method for constructing cast-in-place piles, which can adapt to complex strata, and has high drilling efficiency and good drilling quality.

[0006] On the one hand, this application provides a combined drilling rig coordination device, which adopts the following technical solution: A combined drilling rig coordination device includes a moving component, a base, an adjusting component, a seat, a frame, and a drilling component; The moving component is disposed at the bottom of the base and includes a body, a track, a first driving member and a second driving member. The body is rotatably connected to the base, and the track is movably connected to the body. The first driving member is used to drive the base to rotate, and the second driving member is used to drive the track to move, thereby driving the base to move. The direction of movement of the base is perpendicular to the rotation axis of the body. The base is disposed on the top of the base and is movably connected to the base in a direction perpendicular to the rotation axis of the machine body; the frame is rotatably mounted on the top of the base and its rotation axis is parallel to the rotation axis of the machine body; The adjustment assembly includes a third drive member and a fourth drive member; the third drive member is used to drive the seat to move, and the fourth drive member is used to drive the frame to rotate. The drilling assembly is mounted on the frame and includes a rotary drilling rig and an impact drilling rig. The rotary drilling rig includes a rotary drill bit whose rotation axis is parallel to the rotation axis of the frame. The impact drilling rig includes an impact drill bit whose impact direction is parallel to the rotation axis of the frame. The distance between the rotary drill bit and the rotation axis of the frame is equal to the distance between the impact drill bit and the rotation axis of the frame.

[0007] By adopting the above technical solution, construction personnel can easily position the combined drilling rig and its auxiliary device during the construction of cast-in-place piles. At the same time, it makes it easier and faster for construction personnel to select the appropriate drilling method according to the geological conditions, thereby further improving the construction efficiency of pile holes.

[0008] Optionally, the rotary drilling bit and the impact drilling bit are located on opposite sides of the frame, and the line connecting the rotary drilling bit and the impact drilling bit intersects the rotation axis of the frame.

[0009] By adopting the above technical solutions, the probability of mutual influence between rotary drilling rigs and impact drilling rigs can be effectively reduced. At the same time, the center of gravity of the combined drilling rig cooperative device can be shifted away from the pile hole during the drilling process of the drilling components, thereby improving the stability of the combined drilling rig cooperative device during operation. In addition, the probability of the surrounding strata collapsing due to the gravity of the combined drilling rig cooperative device during pile hole construction can be reduced.

[0010] Optionally, it also includes a support assembly, wherein the top of the base has a placement area on one side of the frame for placing the rotary drilling bit or the impact drilling bit, and the support assembly is disposed on the base and located in the placement area; The support assembly includes a support member, which includes a base plate and a baffle. The base plate is used to support the rotary drilling bit or the impact drilling bit. The baffle is disposed on the side of the base plate near the frame, and the base plate and the baffle together form a storage groove that is compatible with both the rotary drilling bit and the impact drilling bit.

[0011] By adopting the above technical solutions, the force exerted on the frame by one drilling rig or impact drilling rig during the drilling process of one rig or impact drilling rig can be reduced, thereby improving the structural stability of the frame during the operation of the drilling components, and further improving the stability of the combined drilling rig cooperative device during operation; in addition, it is convenient to place the rotary drilling bit or impact drilling bit in the storage area when not in use, and it is also convenient for construction personnel to clean up the unused rotary drilling bit or impact drilling bit and reduce the impact of the removed sludge on other structures.

[0012] Optionally, the support member further includes a guide plate; the guide plate is disposed on the side of the base plate away from the baffle, and the guide plate is inclined downward in a direction away from the base plate.

[0013] By adopting the above technical solution, the guide plate can facilitate the discharge of sludge obtained by rotary drilling bit or impact drilling bit from the storage tank, making it easier for sludge to be centrally accumulated or centrally collected and treated.

[0014] Optionally, the support assembly further includes a movable platform, and the support member is disposed on the top of the movable platform; The mobile platform is movably connected to the base, and the direction of movement of the mobile platform is parallel to the direction of movement of the base; the mobile platform is engaged with the frame, and the movement of the base drives the mobile platform to move synchronously and in the same direction through the frame, and the relative position of the mobile platform and the base remains unchanged during the rotation of the frame.

[0015] By adopting the above technical solution, the support components can be easily adjusted with the displacement of the frame, thereby facilitating the placement of rotary drilling bits or impact drilling bits in the storage slot after the frame is rotated.

[0016] Optionally, a cleaning assembly may also be included, and the cleaning assembly includes a plurality of cleaning brushes; The cleaning brush is disposed on the side of the baffle near the storage slot, and the cleaning brush is used to contact the surface of the rotary drilling bit or the surface of the impact drilling bit.

[0017] By adopting the above technical solution, the cleaning brush can clean the surface of the rotary drilling bit during the process of rotating and throwing mud in the storage trough; the cleaning brush can also clean the surface of the impact drilling bit during the process of placing it in the storage trough; this can improve the cleaning efficiency and effect of rotary drilling bits and impact drilling bits, and at the same time facilitate the subsequent use of rotary drilling bits or impact drilling bits.

[0018] Optionally, the cleaning assembly further includes a plurality of spiral rods corresponding one-to-one with the plurality of cleaning brushes, and the support assembly further includes a plurality of elastic elements; Both ends of the spiral rod are provided with spiral grooves, and the axis of the spiral rod coincides with the axis of the spiral rod. The cleaning brush is disposed on the spiral rod and located between the two spiral grooves. The baffle is provided with a plurality of clearance grooves communicating with the storage groove. The plurality of cleaning brushes are respectively located in the plurality of clearance grooves. The support member is provided with a plurality of balls that roll inside the baffle, and the balls cooperate with the adjacent spiral grooves. The support member is movably connected to the moving platform, and its direction of movement is parallel to the axial direction of the screw rod. The two ends of the elastic member are respectively connected to the support member and the moving platform, and the elastic member has the tendency to drive the support member to move to its limit position away from the moving platform and maintain it. The bottom of the spiral rod is rotatably connected to the moving platform, and its rotation axis coincides with its own axis; during the movement of the base plate, the support member drives multiple spiral rods to rotate, thereby driving multiple cleaning brushes to rotate.

[0019] By adopting the above technical solution, the rotating auger can drive the cleaning brush to rotate and clean the surface of the rotary drilling bit and the impact drilling bit, thereby further improving the cleaning efficiency and cleaning effect of the cleaning component on the surface of the rotary drilling bit and the impact drilling bit. At the same time, the vibration of the base plate under the action of the elastic element can help the sludge in the storage tank to be discharged through the drain port.

[0020] Optionally, the baffle is further provided with a plurality of cleaning blocks in the relief groove. The plurality of cleaning blocks are distributed at equal intervals in the relief groove along the movement direction of the support member, and the bristle distribution area on the cleaning brush is also distributed at equal intervals along the axial direction of the spiral rod. The cleaning block has cleaning holes for the bristles of the cleaning brush to bend and deform before passing through. The spiral rod passes through a plurality of adjacent cleaning holes, and both ends of the cleaning holes along the axial direction of the spiral rod are flared outward. The cleaning block has multiple arc-shaped grooves on the wall of the cleaning hole, and the multiple arc-shaped grooves are arranged in a circumferential array on the wall of the cleaning hole with the axis of the spiral rod as the axis. When the support member moves to its limit position relative to the moving platform, the cleaning block is located between adjacent bristle distribution areas on the cleaning brush; during the process of the support member moving and driving the spiral rod to rotate, the bending deformation trend of the bristles of the cleaning brush in contact with the surface of the rotary drilling bit or the surface of the impact drilling bit is opposite to the bending deformation trend of the bristles of the cleaning brush in contact with the groove wall of the arc-shaped groove.

[0021] By adopting the above technical solution, the cleaning brush can easily achieve self-cleaning during the cleaning process of rotary drilling bit or impact drilling bit surface, so as to ensure the cleaning effect of the cleaning brush on sludge; at the same time, during the cleaning process of the cleaning block, the cleaning brush can effectively correct the deformation of the brush bristles during the cleaning process of the drill bit surface, thereby effectively ensuring the stability and reliability of the cleaning effect of the brush bristles on the drill bit surface.

[0022] Optionally, the baffle has a cylindrical structure, and a drain outlet for discharging mud is provided on the bottom side of the baffle near the guide plate.

[0023] By adopting the above technical solution, the cleaning effect of the cleaning component on the surface of rotary drilling bits and impact drilling bits can be improved, and the impact of sludge splashing on the surrounding area during the cleaning process of rotary drilling bits and impact drilling bits can be further reduced.

[0029] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0030] Example 1: This application discloses a combined drilling rig cooperative device for drilling holes in the foundation.

[0031] Reference Figure 1 and Figure 2 The combined drilling rig coordination device includes a moving component 1, a base 2, an adjusting component 3, a seat 4, a frame 5, a drilling component 6, a supporting component 7, and a cleaning component 8. The moving component 1 drives the base 2 to move above the foundation, facilitating the determination of the borehole location by the combined drilling rig coordination device. The drilling component 6 allows construction personnel to select an appropriate drilling method to drill into the foundation based on the geological conditions. The adjusting component 3 drives the seat 4 and frame 5 to move, allowing for fine-tuning of the drilling position of the drilling component 6 and facilitating switching of drilling methods by construction personnel. The supporting component 7 provides a place for unused drilling rig structures. The cleaning component 8 cleans unused drilling rig structures, facilitating their subsequent use.

[0032] The movable component 1 is installed at the bottom of the base 2 and is used to move the seat 4 on the ground, while also being used to adjust the position of the base 2.

[0033] The mobile component 1 includes a body 11, tracks 12, a first drive component 13, and a second drive component 14.

[0034] Preferably, the base 2 has a rectangular plate-like structure, which is rotatably connected to the body 11. Its axis of rotation is parallel to its height, and the position where it is rotatably connected to the body 11 is centered on its bottom end face. The first driving component 13 is fixedly installed inside the body 11 and is used to drive the base 2 to rotate relative to the body 11. In this embodiment, the first driving component 13 is preferably a servo motor. Since servo motors are common existing technology, they will not be described in detail here, and are only briefly shown in the accompanying drawings.

[0035] Tracks 12 are movably mounted on the body 11, serving to contact and abut against the ground, and during their movement relative to the body 11, they can drive the body 11 to move along the ground above it. A second drive unit 14 is fixedly mounted on the body 11, used to drive the tracks 12 to move relative to the body 11. In this embodiment, preferably, tracks 12 are mounted on both sides of the body 11, and the two tracks 12 are driven synchronously and in the same direction by the same second drive unit 14. Preferably, the second drive unit 14 is a servo motor. Since tracks 12 with the above functions are common prior art, they will not be described in detail here, and are only briefly shown in the accompanying drawings.

[0036] When the track 12 contacts the ground, the position of the base 4 can be adjusted by driving the base 4 to rotate relative to the machine body 11 through the first drive member 13. The movement of the track 12 relative to the machine body 11 by driving the second drive member 14 can move the machine body 11, the base 2, and even the combined drilling rig cooperative device as a whole along the ground.

[0037] The base 4 is movably mounted on the top of the base 2, and its direction of movement is parallel to the length direction of the base 2; the frame 5 is rotatably mounted on the top of the base 4, and its axis of rotation coincides with its own vertical center line and is parallel to the height direction of the base 2.

[0038] The adjustment assembly 3 includes a third drive member 31 and a fourth drive member 32. The third drive member 31 is fixedly mounted on the base 2 and is used to drive the seat 4 to move relative to the base 2; the fourth drive member 32 is fixedly mounted inside the seat 4 and is used to drive the frame 5 to rotate relative to the seat 4. In this embodiment, the third drive member 31 is preferably a lead screw drive structure, and the fourth drive member 32 is preferably a servo motor; since the lead screw drive structure is a common prior art, it will not be described in detail here, and it is only briefly shown in the accompanying drawings.

[0039] The drilling assembly 6 is mounted on the frame 5 and includes a rotary drilling rig 61 and an impact drilling rig 62 with different drilling methods. The rotary drilling rig 61 includes a rotary drill bit 611 and a drive structure for driving the rotary drill bit 611 to move and rotate. The impact drilling rig 62 includes an impact drill bit 621 and a drive structure for driving the impact drill bit 621 to move and impact. In this embodiment, it is preferred that both the rotary drill bit 611 and the impact drill bit 621 are cylindrical in shape. Since both the rotary drilling rig 61 and the impact drilling rig 62 are existing technologies in the art, their drive structures will not be described in detail here, and the drive structures of both are only briefly shown in the accompanying drawings.

[0040] After the drilling assembly 6 is installed on the frame 5, the rotary drilling bit 611 and the impact drilling bit 621 will be located on both sides of the frame 5, and both will be in a vertical position. The distance between the rotary drilling bit 611 and the rotation axis of the frame 5 and the distance between the impact drilling bit 621 and the rotation axis of the frame 5 are equal. At this time, controlling the fourth drive unit 32 to drive the frame 5 to rotate 180° relative to the base 4 will allow the rotary drilling bit 611 and the impact drilling bit 621 to switch positions.

[0041] After the moving component 1 moves the base 2 to one side of the position to be drilled on the foundation, the third drive component 31 is controlled to drive the base 4 to move towards the drilling position. When the distance between the center line of the position to be drilled on the foundation and the rotation axis of the rotary drill bit 611 and the frame 5 and the distance between the impact drill bit 621 and the rotation axis of the frame 5 are equal, the fourth drive component 32 is controlled to drive the frame 5 to rotate relative to the base 4 so that the applicable rotary drill bit 611 or impact drill bit 621 is aligned with the position to be drilled on the foundation in the vertical direction, ready to drill.

[0042] When the base 2 moves to the side of the foundation to be drilled under the drive of the moving component 1, during the drilling process of the drilling component 6, there is always a situation where the rotary drill bit 611 or the impact drill bit 621 is located on the side of the frame 5 away from the position of the hole to be drilled on the foundation. At the same time, there is a placement area 9 above the base 2 on the side of the base 4 away from the position of the hole to be drilled on the foundation for the temporary placement of unused rotary drill bits 611 or impact drill bits 621.

[0043] Reference Figure 2 and Figure 3 The support assembly 7 is mounted on the base 2 and located in the placement area 9, and includes a support member 71, a moving platform 72 and a plurality of elastic members 73.

[0044] The movable platform 72 is mounted on the top of the base 2 and is movably connected to the base 2, with its direction of movement parallel to that of the seat 4. The end of the movable platform 72 near the frame 5 engages with the frame 5, allowing the frame 5 to drive the movable platform 72 synchronously and in the same direction as the seat 4 moves relative to the base 2. Furthermore, the movable platform 72 maintains a stable relative position to the seat 4 during rotation of the frame 5. In this embodiment, preferably, the top of the end of the movable platform 72 near the frame 5 has an arc-shaped groove 7142 with a circular arc trajectory. The bottom of the frame 5 near the edge has an annular groove that matches the arc-shaped groove 7142. The movable platform 72 engages with the frame 5 by fitting the arc-shaped groove 7142 into the annular groove.

[0045] The support member 71 is mounted on the top of the movable platform 72 and is movably connected to the movable platform 72, with its direction of movement parallel to the height direction of the base 2. The elastic member 73 is installed between the support member 71 and the movable platform 72, with its two ends fixedly connected to the support member 71 and the movable platform 72 respectively, and has the tendency to drive the support member 71 to move upward to its limit position and hold it there. In this embodiment, the elastic member 73 is preferably a compression spring.

[0046] Reference Figure 3 and Figure 4 The support member 71 includes a base plate 711, a baffle 712, and a guide plate 713.

[0047] The base plate 711 has an overall circular plate structure. The support member 71 is movably connected to the moving platform 72 through the base plate 711, and the axis of the base plate 711 is parallel to the direction of movement of the support member 71. In this embodiment, it is preferable that the radial dimension of the base plate 711 is larger than the radial dimension of the rotary drilling bit 611 and the radial dimension of the impact drilling bit 621.

[0048] The baffle 712 is fixedly installed on the top of the base plate 711 and distributed around the edge of the base plate 711. In this embodiment, the baffle 712 is preferably cylindrical in shape, with its axis coinciding with the axis of the base plate 711, and together with the base plate 711, it forms a storage groove 10 above the base plate 711 for placing the rotary drilling bit 611 or the impact drilling bit 621; and preferably, the dimension of the baffle 712 in the axial direction is larger than the dimension in the axial direction of the rotary drilling bit 611 and the dimension in the axial direction of the impact drilling bit 621.

[0049] Reference Figure 2 and Figure 3 After use, the rotary drilling bit 611 and the impact drilling bit 621 are covered with sludge. The bottom of the baffle 712 is provided with a sludge discharge port 7121 that is connected to the outside of the storage trough 10 and allows the sludge to be discharged. The sludge discharge port 7121 is located on the side of the baffle 712 away from the frame 5.

[0050] The guide plate 713 is fixedly installed on the side of the base plate 711 away from the frame 5. Its length direction is inclined downward in the direction away from the frame 5. It is used to guide the sludge discharged from the storage trough 10 through the drain port 7121 to fall onto the ground on the side of the base 2 away from the drilling position.

[0051] Reference Figure 3 and Figure 4 The cleaning component 8 is installed on the moving platform 72 and is used to clean the surface of the rotary drilling bit 611 or the impact drilling bit 621 in the storage tank 10 to remove the mud from the surface so that the rotary drilling bit 611 or the impact drilling bit 621 can be put into use again.

[0052] The cleaning assembly 8 includes multiple spiral rods 81 and multiple cleaning brushes 82, and the multiple spiral rods 81 and multiple cleaning brushes 82 correspond one-to-one.

[0053] Reference Figure 3 and Figure 5 The spiral rod 81 has a cylindrical rod-like structure, with spiral grooves 811 at both ends along its length. The axis of the spiral trajectory of the spiral grooves 811 coincides with the axis of the spiral rod 81, and the spiral directions of the multiple spiral grooves 811 on the multiple spiral rods 81 are all the same. The corresponding cleaning brush 82 is fixedly installed on the spiral rod 81, distributed on the radial circumference of the spiral rod 81 and located between two spiral grooves 811. In this embodiment, the cleaning brush 82 preferably has a large number of soft bristles, which achieve the effect of removing sludge. Since the above-mentioned cleaning brush 82 is common prior art, it will not be described in detail here, and it is only briefly shown in the accompanying drawings.

[0054] Reference Figure 4 and Figure 5The bottom of the spiral rod 81 is rotatably connected to the moving platform 72, and its rotation axis coincides with its own axis and is parallel to the direction of movement of the support member 71. The spiral rod 81 is partially inserted into the support member 71. The support member 71 has multiple balls 7123 that are adapted to the spiral grooves 811 and are rolled inside the baffle 712. The balls 7123 can roll relative to the baffle 712 while their centers remain relatively stable with the baffle 712. The multiple spiral rods 81 are inside the baffle 712, and each spiral groove 811 has a corresponding ball 7123 that engages with it. The support member 71 has multiple clearance grooves 7122 that communicate with the storage groove 10 on the side of the baffle 712 near the storage groove 10. The multiple clearance grooves 7122 correspond one-to-one with multiple cleaning brushes 82. The bristles of the cleaning brushes 82 can enter the storage groove 10 through the corresponding clearance grooves 7122 for cleaning. In this embodiment, it is preferable that a plurality of clearance grooves 7122 are arranged in a circular array on the baffle 712 with the axis of the baffle 712 as the axis, and preferably the bottom of the clearance grooves 7122 is an inclined surface that slopes downward toward the storage groove 10, so that the sludge removed by the cleaning brush 82 can enter the clearance grooves 7122 and leave; correspondingly, the installation positions of a plurality of spiral rods 81 on the moving platform 72 are also arranged in a circular array with the axis of the baffle 712 as the axis.

[0055] During the movement of the support member 71 relative to the moving platform 72, the cleaning brush 82 remains in the corresponding clearance groove 7122. During this process, the ball bearing 7123 will contact and abut against the groove wall of the corresponding spiral groove 811, thereby driving the spiral rod 81 to rotate relative to the moving platform 72. This, in turn, drives multiple spiral rods 81 to rotate synchronously and in the same direction relative to the moving platform 72, thereby driving the corresponding multiple cleaning brushes 82 to rotate, improving the cleaning effect and efficiency of the cleaning brushes 82. In this embodiment, since the method of realizing the movement of the support member 71 to drive the spiral rod 81 to rotate is a common existing technology, it will not be described in detail here, and it is only briefly shown in the accompanying drawings. In practical applications, by injecting lubricating oil into the interior of the baffle 712 through the opening in the support member 71 at the top of the baffle 712 for the spiral rod 81 to pass through, the reliability and stability of the effect of the support member 71 moving to drive the spiral rod 81 to rotate can be effectively guaranteed.

[0056] Reference Figure 2 and Figure 4After the rotary drilling bit 611 is used and the impact drill bit 621 is switched on, the sludge inside the rotary drilling bit 611 can be thrown out into the storage groove 10 and then discharged through the drain port 7121 along the guide plate 713. At the same time, the rotation of the rotary drilling bit 611 during the process of throwing out the sludge facilitates multiple cleaning brushes 82 to clean the surface of the rotary drilling bit 611. Finally, the sludge on its surface can also be discharged through the drain port 7121 along the guide plate 713. After the sludge is thrown out, the rotary drilling bit 611 will be placed directly on the support member 71. Its gravity will drive the support member 71 to move downward, which will trigger multiple screw rods 81 to rotate, thereby cleaning the surface of the rotary drilling bit 611 again.

[0057] After the impact drill bit 621 is used and then the rotary drill bit 611 is used, the impact drill bit 621 is placed in the storage groove 10 and its gravity drives the support member 71 to move downward. At the same time, multiple spiral rods 81 can be triggered to rotate, driving multiple cleaning brushes 82 to clean the surface of the impact drill bit 621.

[0058] After the rotary drilling bit 611 or the impact drilling bit 621 is placed on the support member 71, the load on the frame 5 by the unused rotary drilling bit 611 or the impact drilling bit 621 can be effectively reduced, so as to effectively ensure the stability of the drilling assembly 6. At the same time, it can shift the center of gravity of the combined drilling rig coordination device to a direction away from the drilling position, so as to reduce the probability that the combined drilling rig coordination device will exert pressure on the foundation, causing the pile hole to be affected, deformed or even collapsed.

[0059] In this embodiment, the combined drilling rig coordination device is preferably controlled by a remote control system and the remote control system is kept at a certain distance from the combined drilling rig coordination device; in other embodiments, the control system can also be fixedly installed at the bottom of the frame 5, and the construction personnel can ride on the combined drilling rig coordination device to control the combined drilling rig coordination device; since the remote control system with the above functions is a common prior art, it will not be described in detail here, and its expression is omitted in the accompanying drawings.

[0060] The implementation principle of a combined drilling rig coordination device in this application is as follows: The control moving component 1 drives the base 2 to move to one side of the position to be drilled on the foundation. Then, according to the stratum conditions, the appropriate rotary drilling rig 61 or impact drilling rig 62 is selected. The frame body 5 is controlled to rotate so that the corresponding rotary drilling bit 611 or impact drilling bit 621 is located on the side of the frame body 5 close to the position to be drilled. Then, the base 2 is controlled to rotate, the base body 4 is moved, and the frame body 5 is controlled to rotate so that the rotary drilling bit 611 or impact drilling bit 621 is aligned with the position of the hole to be drilled, and drilling can then begin. During the use of rotary drilling rig 61 or impact drilling rig 62, unused rotary drilling bits 611 or impact drilling bits 621 will be placed in storage trough 10 and supported by support member 71 to improve the stability of the combined drilling rig during operation. Used rotary drilling bits 611 or impact drilling bits 621 will be cleaned by cleaning component 8 in storage trough 10, and the sludge removed by cleaning will leave through drain port 7121 in storage trough 10 and be discharged along guide plate 713 on the side of base 2 away from the drilling position, so that sludge can be collected and processed in a container.

[0061] Example 2: Reference Figure 6 and Figure 7 The difference between this embodiment and embodiment 1 lies in the support component 7 and the cleaning component 8.

[0062] The baffle 712 of the support member 71 has multiple cleaning blocks 714 in multiple relief grooves 7122 for cleaning the bristles on the cleaning brush 82. The multiple cleaning blocks 714 are evenly distributed in the relief grooves 7122 along the axial direction of the baffle 712. The bristle distribution area on the cleaning brush 82 is also evenly distributed along the length direction of the cleaning brush 82, and the interval between adjacent bristle distribution areas on the cleaning brush 82 is adapted to the size of the cleaning blocks 714 along the axial direction of the baffle 712.

[0063] The cleaning block 714 has a cleaning hole 7141 extending through it along a direction parallel to the axis of the baffle 712, through which the bristles can bend and deform. The corresponding spiral rod 81 passes through the cleaning hole 7141, and the axis of the cleaning hole 7141 coincides with the axis of the corresponding spiral rod 81. Both ends of the cleaning hole 7141 are flared outward to guide the bristles through the cleaning hole 7141 after deformation. In this embodiment, preferably, the minimum radial dimension of the cleaning hole 7141 is greater than the radial dimension of the bristle-free area on the cleaning brush 82 and smaller than the radial dimension of the bristle area on the cleaning brush 82. During the process of the bristles on the cleaning brush 82 passing through the cleaning hole 7141, they can contact and abut against the hole wall of the cleaning hole 7141, thereby separating the sludge attached to the bristle surface. The separated sludge can then enter the storage groove 10 through the clearance groove 7122 under its own gravity.

[0064] The cleaning block 714 has multiple arc-shaped grooves 7142 formed on the flared wall of the cleaning hole 7141, and the multiple arc-shaped grooves 7142 are arranged in a circumferential array on the cleaning block 714 with the axis of the cleaning hole 7141 as the axis. In this embodiment, it is preferable that the multiple arc-shaped grooves 7142 are radially distributed on the cleaning block 714 with respect to the axis of the cleaning hole 7141.

[0065] The support member 71 drives the spiral rod 81 to rotate the cleaning brush 82. Simultaneously, as a bristle distribution area on the cleaning brush 82 passes through the adjacent cleaning hole 7141, the bristles in this distribution area rotate and contact the drill bit surface before entering the cleaning hole 7141, achieving a cleaning effect. During this process, the drill bit surface tends to cause the bristles to bend and deform in one direction. Afterwards, as the support member 71 drives the bristles in this distribution area of ​​the cleaning brush 82 to pass through the cleaning hole 7141, the hole wall of the cleaning hole 7141 above the bristles will cause the brush... The bristles bend and deform downwards, and at the same time, guided by the arc groove 7142, the bristles bend and deform in the opposite direction to the direction that previously caused the drill bit surface to bend and deform. Afterwards, during the process of the support member 71 moving and resetting under the action of the elastic member 73, the force exerted by the hole wall of the cleaning hole 7141 on the bristles can drive the bristles to bend and deform upwards. This effectively avoids the bristles being subjected to the same force in the same direction for a long time, which would cause the bristles to bend and deform in the same direction, resulting in the loss of elasticity and permanent deformation. This would lead to a reduction in the cleaning effect and efficiency of the bristles on the drill bit surface, or even a situation where the drill bit surface cannot be cleaned at all.

[0066] Furthermore, preferably, when the support member 71 is in the state of moving upward to the limit position and moving downward to the limit position, the stroke of the support member 71 is equal to the dimension of the cleaning block 714 along the axis of the support member 71; and when the support member 71 moves to the limit position relative to the moving table 72, the multiple cleaning blocks 714 are all located between adjacent bristle distribution areas on the cleaning brush 82.

[0067] The implementation principle of a combined drilling rig coordination device in this application is as follows: As the drill bit is placed in the storage slot 10 and the support 71 moves downward, the cleaning component 8 cleans the surface of the drill bit in the storage slot 10. During this process, the bristles on the cleaning brush 82 will bend and deform after contacting the surface of the drill bit and remove the dirt from the surface of the drill bit. At the same time, the cleaning block 714 will move downward relative to the bristles on the cleaning brush 82 so that the bristles pass through the corresponding cleaning hole 7141. As the bristles pass through the cleaning hole 7141, they will bend and deform downward. At the same time, under the action of multiple arc-shaped grooves 7142, the bending deformation of the bristles on the surface of the drill bit will be eliminated. When the drill bit in the storage slot 10 is reused, the support 71 moves upward and resets under the action of the elastic member 73. As the bristles pass through the cleaning hole 7141, they bend upward and deform to eliminate the effect of the previous downward bending deformation. At the same time, under the action of multiple arc-shaped grooves 7142, they continue to eliminate part of the bending deformation effect on the surface of the drill bit. Ultimately, the bristles on the cleaning brush 82 can maintain a high cleaning effect and efficiency even after long-term cleaning of the drill bit surface.

[0068] Example 3: Reference Figure 1 and Figure 2 This application discloses a method for constructing cast-in-place piles, based on a combined drilling rig and cooperative device disclosed in Embodiment 1 or Embodiment 2, for completing pile foundation drilling in complex geological conditions, including the following steps: S1. Install casing.

[0069] Bury the casing on the foundation and prepare enough mud and clay for the casing.

[0070] The preferred casing is fixed to the ground by welding or bolting, with its top 0.3m above the ground and its bottom buried in a stable stratum.

[0071] Furthermore, it is preferable to use a double-casing structure, with the inner casing used to fix the orifice and the outer casing used to prevent groundwater seepage. Since both the casing and the double-casing structure are existing technologies in this field, they will not be described in detail here.

[0072] S2, Positioning of the combined drilling rig coordination device.

[0073] The control unit moves the combined drilling rig on the ground to align the drill bit with the center of the pile hole, ensuring the verticality of the hole.

[0074] S3. Fill the casing with mud.

[0075] Before drilling, mud (i.e. wall-protecting mud clay) is poured into the casing. The relative density and other indicators of the mud are determined according to the soil conditions.

[0076] In this embodiment, a mud circulation system is preferably formed between the surface and the space inside the borehole. In the mud circulation system, a mud pump transports mud from the mud pool to the borehole through pipelines, and maintains the water level inside the borehole at least 0.5m above the groundwater level.

[0077] Furthermore, it is preferable to add mud additives (such as polymers) to the wall-protecting mud clay to improve the wall-protecting effect of the mud.

[0078] S4. Select either rotary drilling rig 61 or impact drilling rig 62 based on the geological conditions.

[0079] Rotary drilling rig 61 is used to drill holes in soil and rock layers using rotary drilling mode, and impact drilling rig 62 is used to drill holes in sand and gravel layers using impact drilling mode.

[0080] During drilling, the advance should be properly controlled; at the cutting edge of the casing, drilling should be slow to ensure that there is a solid mud skin protecting the cutting edge.

[0081] After drilling to 1m below the cutting edge of the casing, you can continue drilling at a normal speed depending on the soil conditions.

[0082] If the soil outside the casing is soft and leakage is found, the drill bit can be lifted, mud can be poured into the hole, and then the drill bit can be lowered (drilling) to impact and force the mud into the hole wall to block the leakage gap, stabilize the mud and continue drilling.

[0083] When drilling in sandy or soft soil layers, borehole collapse is likely. Therefore, it is advisable to use a flat-bottomed drill bit, control the drilling depth, apply light pressure, use a short stroke and slow speed, employ a large pump volume, and use thick mud. Throughout the drilling process, the water level in the borehole must always be maintained at least 0.5m higher than the groundwater level and 0.3m lower than the top surface of the casing to prevent overflow. After slag removal, water should be promptly added to the borehole to maintain a certain water head.

[0084] To prevent the vibration of the piling machine from causing the collapse of adjacent hole walls or affecting the setting of the concrete already poured in adjacent holes, drilling can only begin after the concrete in adjacent holes has been poured and reached a compressive strength of 5.0 MPa, so as to avoid vibration affecting the quality of the concrete.

[0085] During drilling, replenish any lost or leaked mud as needed to maintain the mud density in the borehole. Regularly check and record the mud density and borehole depth to prevent borehole collapse, shrinkage, over-drilling, and other adverse factors. Fill out the "Drilling Record Form" as required based on the actual situation during drilling.

[0086] When the borehole reaches the design elevation, the borehole depth, diameter, shape, and sediment thickness should be checked, and the geological conditions should be verified by the supervising engineer and design representative. Once confirmed, the borehole should be cleaned immediately to prevent prolonged intervals that could lead to borehole collapse or drill cuttings settling.

[0087] 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.
