Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a collaborative construction device for in-situ solidification agent injection and auger drilling of port reclamation soil. Background Technology

[0002] When constructing a port, the high moisture content in the soil layer at the port location leads to low soil strength, making the foundation prone to settlement. It is usually necessary to inject concrete or other hardeners into the foundation so that the hardener mixes with the soil to form a high-strength foundation structure.

[0003] When injecting curing agents into the foundation, high-pressure jet grouting is usually used to inject grout such as concrete into the soil layer. First, a high-pressure jet grouting drill bit is used to drill downwards into the soil layer to break up the soil. When the preset depth is reached, the high-pressure jet grouting drill bit rotates in the opposite direction and lifts upwards. The high-pressure grout inside the drill rod is sprayed into the borehole from the drill bit. As the high-pressure jet grouting drill bit rotates, the grout is sprayed in a rotating manner, which mixes the grout with the broken soil. The mixing of the broken soil in the borehole by the high-pressure jet grouting drill bit is mainly achieved through the rotating spraying action at the bottom of the drill bit. Furthermore, during the upward lifting process, the drill bit can only mix the soil at the position reached by the drill bit. The mixing time is short, which can easily lead to insufficient mixing and uneven distribution of the soil, affecting the full mixing of the soil and grout. Summary of the Invention

[0044] The beneficial technical effects of the present invention are as follows:

[0045] The fixed bracket provides stable support for the entire equipment, ensuring the positional stability of the high-pressure jet grouting drill rod during drilling and grouting. The high-pressure jet grouting drill rod can both drill downwards into the port soil layer to break up the soil and inject the curing agent under high pressure. Simultaneously, the drive structure at its top, with the reliable connection of the mounting structure, drives the mixing structure located on the outer wall of the high-pressure jet grouting drill rod to be retracted and deployed. During the drilling phase, the mixing structure can be retracted to avoid obstructing the drilling operation. When mixing is required, the drive structure drives the mixing structure to deploy, so that the mixing effect is no longer limited to the bottom drill bit position, but actively mixes the mud at different depths within the borehole. Combined with the drilling and reverse rotation lifting action of the high-pressure jet grouting drill rod, the mixing time between the curing agent and the broken soil is significantly extended. This effectively improves the problem of insufficient mixing caused by relying solely on drill bit rotation and jetting in traditional methods, promoting uniform mixing of the curing agent and soil, thereby increasing the strength of the reinforced soil layer, reducing settlement during port foundation construction, and ensuring the stability and reliability of the foundation structure.

[0046] This invention utilizes a combination of a high-pressure jet grouting drill rod, a connecting column, a second movable groove, an extrusion groove, a recess, a limiting block, and a movable rod. When the high-pressure jet grouting drill rod rotates in the reverse direction, it drives the connecting column to rotate counterclockwise within the upper second movable groove. The connecting column presses against the other side of the limiting block, and the recess blocks the limiting block, preventing it from rotating. Furthermore, the obliquely positioned limiting block presses and pushes the connecting column, causing it to move downwards into the extrusion groove. As the connecting column rotates, the inner wall of the extrusion groove pushes the connecting column downwards, allowing it to enter the lower second movable groove. This causes the sliding block and the movable rod to move downwards, unfolding multiple mixing blocks for convenient use and storage.

[0047] This invention utilizes a combination of movable rods, fixed columns, connecting grooves, and mixing blocks. By pushing one of the movable rods downward, multiple movable rods move the fixed columns downward together. The fixed columns press against the inner wall of the connecting groove, pushing the mixing blocks downward to a horizontal position. Multiple mixing blocks rotate together with the high-pressure jet grouting drill rod to mix the broken soil, facilitating thorough mixing of the broken soil and slurry.

[0048] This invention utilizes a combination of an installation ring, an installation block, a second installation groove, a positioning block, and a positioning groove. The installation ring is rotatably connected to the high-pressure jet grouting drill rod via the installation block and the second installation groove. When the high-pressure jet grouting drill rod moves vertically, it drives the installation ring and the sleeve to move together. The connecting block and the positioning block move vertically with the installation ring, and the positioning block slides in the positioning groove, preventing the installation ring from rotating and ensuring the stability of the installation ring and the sleeve.

[0065] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0066] The embodiments of the present invention provide, as follows Figures 1 to 10 The illustrated in-situ solidification agent injection and auger drilling equipment for port reclamation includes a fixed support 1, a high-pressure jet grouting drill rod 2, a mixing structure 3, a drive structure 4, and an installation structure 5. The fixed support 1 supports and installs the high-pressure jet grouting drill rod 2, allowing it to move vertically on the support 1. The high-pressure jet grouting drill rod 2 is connected to the drilling rig. The operation of the high-pressure jet grouting drill rod 2 is divided into two stages. In the first stage, the drilling rig drives the high-pressure jet grouting drill rod 2 to move vertically and then rotate, drilling into the foundation. A high-pressure pump continuously delivers grout into the high-pressure jet grouting drill rod 2, filling it with high-pressure grout. In the second stage, the high-pressure jet grouting drill rod 2 rotates in the opposite direction and is lifted upwards at a uniform speed, while the ball valve is released. The immense pressure of the high-pressure grout inside the rotary jet grouting drill rod 2 acts entirely on the lower part of the valve ball. Simultaneously, the rotation of the high-pressure rotary jet grouting drill rod 2 causes the jet to fan-shaped cut and stir the soil, ensuring thorough mixing with the injected grout. The stirring structure 3 is located on the outer wall of the high-pressure rotary jet grouting drill rod 2. The stirring structure 3 is used to stir the mud in the borehole, thoroughly stirring and turning the broken soil to facilitate mixing of the grout and the soil. The drive structure 4 is located at the top of the high-pressure rotary jet grouting drill rod 2. The drive structure 4 is used to drive the stirring structure 3 to be retracted and deployed, facilitating its use. The mounting structure 5 is located on the drive structure 4. The mounting structure 5 is used to install and connect the drive structure 4 to the high-pressure rotary jet grouting drill rod 2, ensuring the stable operation of the drive structure 4.

[0067] like Figure 5 , Figure 6 and Figure 7 As shown, specifically, the stirring structure 3 includes a first mounting groove 31, a stirring block 32, a fixed shaft 33, a connecting groove 34, a first movable groove 35, a movable rod 36, a fixed column 37, and a fixed block 38.

[0068] The first mounting groove 31 is opened on the outer wall of the high-pressure rotary jet drill rod 2. The first mounting grooves 31 are arranged vertically at equal intervals. Multiple first mounting grooves 31 are symmetrically opened on both sides of the outer wall of the high-pressure rotary jet drill rod 2 for installing the mixing block 32.

[0069] The mixing block 32 is set in the first mounting groove 31. The mixing block 32 rotates in the first mounting groove 31, which facilitates the storage of the mixing block 32. When the high-pressure jet grouting drill rod 2 drills downward, the mixing block 32 is stored in the first mounting groove 31. When the high-pressure jet grouting drill rod 2 rotates upward in the opposite direction, the mixing block 32 rotates to a horizontal position and rotates together with the high-pressure jet grouting drill rod 2 to mix and turn the broken soil in the borehole.

[0070] The fixed shaft 33 is fixedly connected to the bottom of the stirring block 32. One end of the fixed shaft 33 is rotatably connected to the inner wall of the first mounting groove 31. The stirring block 32 is rotatably connected to the first mounting groove 31 through the fixed shaft 33, so that the stirring block 32 rotates around the fixed shaft 33.

[0071] A connecting groove 34 is provided on the stirring block 32. The connecting groove 34 is set at an angle and is used to install the fixing column 37.

[0072] The first movable groove 35 is opened on the high-pressure rotary jet drill rod 2, and the first movable groove 35 is used to install the movable rod 36; the movable rod 36 is slidably inserted in the first movable groove 35, and the movable rod 36 is set on one side of the stirring block 32. The movable rod 36 moves in the vertical direction to drive the stirring block 32 to rotate.

[0073] The fixed column 37 is fixedly connected to the outer wall of the movable rod 36. The fixed column 37 and the connecting groove 34 are slidably interlocked. The fixed column 37 moves vertically with the movable rod 36 to press against the inner wall of the connecting groove 34 and push the stirring block 32 to rotate.

[0074] The fixed block 38 is fixedly connected to one end of the movable rod 36. The fixed block 38 is set between two adjacent movable rods 36. One end of the two adjacent movable rods 36 is connected through the fixed block 38, so that multiple movable rods 36 move together. By pushing one of the movable rods 36 downward, multiple movable rods 36 drive the fixed column 37 to move downward together. The fixed column 37 presses against the inner wall of the connecting groove 34, pushing the mixing block 32 to rotate downward to a horizontal position. Multiple mixing blocks 32 rotate together with the high-pressure jet grouting drill rod 2 to mix the broken soil.

[0075] like Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, the drive structure 4 further includes a mounting ring 41, a sleeve 42, a second movable groove 43, a pressing groove 44, a sliding groove 45, a sliding block 46, a connecting column 47, a groove 48, a mounting shaft 49, a limiting block 410, and a torsion spring 411.

[0076] The mounting ring 41 is rotatably inserted into the top of the high-pressure jet grouting drill rod 2. The mounting ring 41 is used to connect the sleeve 42 to the high-pressure jet grouting drill rod 2, so that the high-pressure jet grouting drill rod 2 can rotate in the inner cavity of the mounting ring 41 and the sleeve 42.

[0077] The top end of the sleeve 42 is fixedly connected to the bottom end of the mounting ring 41. The sleeve 42 and the top of the high-pressure jet grouting drill rod 2 are rotatably interlocked. The sleeve 42 is used to drive the connecting column 47 and the sliding block 46 to move.

[0078] The second movable groove 43 is respectively provided at the top and bottom of the outer wall of the sleeve 42. The second movable groove 43 is an annular groove. The second movable groove 43 is used to install and accommodate the connecting column 47. When the high-pressure rotary jet drill rod 2 drills downward, it drives the connecting column 47 to move in a circular motion in the inner cavity of the upper second movable groove 43.

[0079] The extrusion groove 44 is opened in the middle of the outer wall of the sleeve 42. The extrusion groove 44 is arranged between the second movable grooves 43. The extrusion groove 44 is inclined and is used to connect the two second movable grooves 43, so that the connecting column 47 can move in the two second movable grooves 43 through the extrusion groove 44. The inclined surface of the inner wall of the extrusion groove 44 presses against the connecting column 47, pushing the connecting column 47 and the movable rod 36 to move vertically.

[0080] like Figure 5 As shown, the sliding groove 45 is formed on the outer wall of the high-pressure jet grouting drill rod 2. The sliding groove 45 is used to install the sliding block 46, so that the sliding block 46 can move vertically.

[0081] One end of the sliding block 46 is fixedly connected to one of the fixed blocks 38, and the other end of the sliding block 46 is slidably inserted into the sliding groove 45. The sliding block 46 is L-shaped and is used to connect the fixed block 38 and the connecting post 47.

[0082] The connecting column 47 is fixedly connected to the top of the sliding block 46. One end of the connecting column 47 is slidably inserted into the second movable groove 43. As the high-pressure rotary jet drill rod 2 rotates, it drives the sliding block 46 and the connecting column 47 to rotate together.

[0083] like Figure 9As shown, a groove 48 is formed on the inner wall of the second movable groove 43, and the groove 48 is used to install and accommodate the limiting block 410; the mounting shaft 49 is rotatably connected to the inner wall of the groove 48, and the limiting block 410 rotates around the mounting shaft 49; the limiting block 410 is fixedly connected to the outer wall of the mounting shaft 49, and the limiting block 410 is set at an angle. The limiting block 410 is set in the second movable groove 43, and the outer wall of the limiting block 410 is in contact with one side of the inner wall of the groove 48, which is used to limit the movement of the connecting column 47. When the high-pressure rotary jet drill rod 2 drills downward, it drives the sliding block 46 and the connecting column 47 to rotate clockwise. The connecting column 47 presses against one side of the limiting block 410, so that the limiting block 410... 10 rotates upward into the groove 48. When the high-pressure rotary jet drill rod 2 rotates in the opposite direction, it drives the connecting column 47 to rotate counterclockwise in the upper second movable groove 43. The connecting column 47 presses against the other side of the limiting block 410. The groove 48 blocks the limiting block 410, preventing it from rotating. The obliquely set limiting block 410 presses and pushes the connecting column 47, causing it to enter the extrusion groove 44 downward. As the connecting column 47 rotates, the inner wall of the extrusion groove 44 pushes the connecting column 47 downward. The connecting column 47 enters the lower second movable groove 43, causing the sliding block 46 and the movable rod 36 to move downward, thus unfolding the multiple stirring blocks 32.

[0084] The torsion spring 411 is movably sleeved on one end of the mounting shaft 49. One end of the torsion spring 411 is fixedly connected to the inner wall of the groove 48, and the other end of the torsion spring 411 is fixedly connected to the limiting block 410. When the limiting block 410 rotates, it compresses and deforms the torsion spring 411, and uses the elasticity of the torsion spring 411 to drive the limiting block 410 to rotate.

[0085] like Figure 8 and Figure 10As shown, further, the mounting structure 5 includes a second mounting groove 51, a mounting block 52, a connecting block 53, a positioning block 54, and a positioning groove 55. The second mounting groove 51 is formed at the top of the high-pressure jet grouting drill rod 2 and is an annular groove. The second mounting groove 51 is used to install and accommodate the mounting block 52. The mounting block 52 is fixedly connected to the inner wall of the mounting ring 41. The mounting block 52 and the second mounting groove 51 are slidably interlocked. The mounting ring 41 is rotatably connected to the high-pressure jet grouting drill rod 2 through the mounting block 52. The high-pressure jet grouting drill rod 2 rotates within the mounting ring 41 and, with the vertical movement of the high-pressure jet grouting drill rod 2, drives the mounting ring 41 and the sleeve 42 to move together. One end of the connecting block 53 is fixedly connected to the back of the mounting ring 41 and is used to install the positioning block 54. The positioning block 54 is fixedly connected to the other end of the connecting block 53. The positioning block 54 and the connecting block 53 form a T-shaped structure, which is used to connect the mounting ring 41 to the fixed bracket 1. The positioning groove 55 is opened on the inner wall of the fixed bracket 1. The positioning groove 55 is vertically set. The positioning groove 55 and one end of the positioning block 54 are slidably inserted. The positioning groove 55 is used to install the positioning block 54. The mounting ring 41 is rotatably connected to the high-pressure jet grouting drill rod 2 through the mounting block 52 and the second mounting groove 51. When the high-pressure jet grouting drill rod 2 moves vertically, it drives the mounting ring 41 and the sleeve 42 to move together. The connecting block 53 and the positioning block 54 move vertically with the mounting ring 41. The positioning block 54 slides in the positioning groove 55, so that the mounting ring 41 cannot rotate, ensuring the stability of the mounting ring 41 and the sleeve 42.

[0086] like Figure 3 and Figure 4 As shown, a nozzle 6 is fixedly installed at the bottom of the high-pressure jet grouting drill rod 2. The slurry inside the high-pressure jet grouting drill rod 2 is sprayed into the borehole through the nozzle 6. A slurry chamber 7 is opened on the high-pressure jet grouting drill rod 2. The slurry chamber 7 is used to store concrete curing agents. A spiral blade 8 is fixedly connected to the inner wall of the slurry chamber 7. As the high-pressure jet grouting drill rod 2 rotates, it drives the spiral blade 8 to rotate as well, stirring the slurry in the slurry chamber 7 and preventing the slurry from solidifying. A delivery pipe 9 is fixedly installed at the top of the high-pressure jet grouting drill rod 2. The conveying pipe 9 is connected to an external high-pressure pump to convey the slurry, allowing it to enter the slurry chamber 7. One end of the conveying pipe 9 is connected to the slurry chamber 7. The bottom of the high-pressure jet grouting drill rod 2 is conical. Protrusions 10 are fixedly connected to the outer wall of the bottom of the high-pressure jet grouting drill rod 2. The protrusions 10 are arranged in a ring array at equal intervals. The protrusions 10 are triangular blocks. The protrusions 10 rotate together with the high-pressure jet grouting drill rod 2, which facilitates the breaking of the soil and the drilling of the drill bit at the bottom of the high-pressure jet grouting drill rod 2.

[0087] The two ends of the extrusion groove 44 are respectively connected to the inner cavities of the two second movable grooves 43, so that the connecting column 47 can move between the two second movable grooves 43. The extrusion groove 44 and the connecting column 47 are slidably interlocked. The extrusion groove 44 is used to extrude and push the connecting column 47. The extrusion groove 44 is symmetrically arranged on both sides of the outer wall of the sleeve 42. The symmetrically arranged extrusion grooves 44 extrude and push the two connecting columns 47 synchronously.

[0088] The working principle of this invention is as follows: When the high-pressure jet grouting drill rod 2 drills downwards, it drives the sliding block 46 and the connecting column 47 to rotate clockwise. The connecting column 47 presses against one side of the limiting block 410, causing the limiting block 410 to rotate upwards into the groove 48. When the high-pressure jet grouting drill rod 2 rotates in the opposite direction, it drives the connecting column 47 to rotate counterclockwise in the upper second movable groove 43. The connecting column 47 presses against the other side of the limiting block 410, and the groove 48 blocks the limiting block 410, preventing the limiting block 410 from rotating. Furthermore, the obliquely positioned limiting block 410 blocks the connecting column 47. The squeezing and pushing action causes the connecting column 47 to move downwards into the squeezing groove 44. As the connecting column 47 rotates, the inner wall of the squeezing groove 44 pushes the connecting column 47 downwards, and the connecting column 47 enters the second movable groove 43 below. This causes the sliding block 46 and the movable rod 36 to move downwards. The multiple movable rods 36 drive the fixed column 37 to move downwards together. The fixed column 37 squeezes against the inner wall of the connecting groove 34, pushing the mixing block 32 to rotate downwards to a horizontal position. The multiple mixing blocks 32 rotate together with the high-pressure rotary jet drill rod 2 to mix the broken soil, which facilitates the mixing of the broken soil and the slurry.

[0089] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
