Description

Technical Field

[0001] This utility model belongs to the technical field of foundation treatment equipment for geotechnical engineering, and in particular relates to a multifunctional foundation treatment plastic drainage board insertion machine. Background Technology

[0002] With the rapid development of society and the economy, the construction of infrastructure is also increasing, such as airports, industrial plants, chemical plants, and power plants. Due to limited land resources, land reclamation is a future development trend in the construction industry. In my country's coastal areas, there are large areas of saturated soft soil, mostly composed of water-rich fine sand, silt, and silty clay. These soil layers have the characteristics of "three highs and one low"—high water content, high compressibility, high sensitivity, and low strength—and poor permeability. Treatment of these soil layers is essential if buildings are to be constructed in these areas. Currently, common drainage consolidation foundation treatment methods in China include surcharge preloading, vacuum preloading, and a combination of vacuum and surcharge preloading. The main purpose of these methods is to increase vertical drainage, accelerate foundation consolidation and strength gain, improve foundation stability, accelerate settlement, expedite foundation settlement, and control post-construction differential settlement.

[0003] Both vacuum preloading and surcharge preloading require the installation of plastic drainage boards. Taking surcharge preloading on tidal flats as an example, a layer of woven fabric is first laid on the site, followed by a layer of gravel to facilitate machinery movement, and then a layer of geotextile to isolate the upper drainage cushion layer. The drainage cushion layer is then constructed, and plastic drainage boards are installed after its completion. The main drainage board installation equipment in China is the board insertion machine, including track-mounted and crawler-mounted types. Installation methods include hydraulic and vibratory hammer methods. Hydraulic methods are mainly suitable for subsoil layers consisting entirely of silt, while vibratory hammer methods are mainly suitable for subsoil layers containing silt, as well as soft plastic and locally plastic silty clay.

[0004] The two existing devices have limitations. When the site to be treated has a thick layer of hard soil (more than 10 meters deep), including dense sand or hard plastic silty clay with a liquidity index (IL) between 0.25 and 0.5, it is difficult to install plastic drainage boards, the drill rod advances slowly or not at all, resulting in longer construction period and increased project cost. In such geological conditions, common board inserters also have a series of disadvantages: (1) The plastic drainage board at the end of the drill bit is located between the drill rod and the lifting iron rod. When encountering a hard interlayer, the drainage board is subjected to excessive shear force and will be clamped by the lifting iron rod and the drill rod, resulting in a "back-carrying" phenomenon and failure to retain the drainage board; (2) The bottom of the drill rod is not completely sealed. During the downward drilling of the plastic drainage board, soil will enter the drill rod, causing pipe blockage and the plastic drainage board to get stuck, resulting in failure to retain the plastic drainage board; (3) After the board inserter is assembled, personnel need to climb to the top of the drill rod to insert the plastic drainage board into the drill rod. The board inserter is generally 30m high, and the safety disadvantage of personnel working at height is obvious; (4) When there is a deep hard interlayer in the geological conditions, the construction efficiency of the plastic drainage board board inserter is low and the failure rate is also very high, such as damage to the vibratory hammer and deformation of the drill rod. To meet the construction schedule requirements, more machinery and equipment must be added. When the equipment fails, additional machinery repair costs and personnel downtime costs will also be incurred, leading to an increase in the overall cost of foundation treatment. Summary of the Invention

[0005] In view of this, this utility model overcomes the defects in the prior art and proposes a multifunctional foundation treatment plastic drainage board insertion machine.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A multifunctional foundation treatment plastic drainage board insertion machine includes a vibration damping and mixing transmission device, a horizontal moving device, a vertical conveying device, a vertical conveying assembly, a drill bit device, a winch, an operating room, a steel frame, support rods, and a walking device.

[0008] The vibration damping and mixing transmission device includes a vibratory hammer, a spring damping vibration damper, a frame, and a fixed top plate. The main drive shaft of the vibration damping and mixing transmission device is driven by the mixing drilling rig to rotate, which in turn drives the active gear, driven gear, and auxiliary drive shaft to rotate. The auxiliary drive shaft drives the driven gear to rotate, which in turn drives the mixing gear to rotate, thereby causing the mixing fan blades at the bottom of the drill rod to rotate.

[0009] The horizontal moving device includes a fixed bracket, a reversing gear, a translation gear, a clutch pair gear, a transmission chain, a horizontal control clutch device, and a fixed base. The rotation of the main drive shaft of the horizontal moving device drives the worm gear to rotate, which in turn drives the steering gear to rotate, thereby causing the forward gear and the steering gear to rotate, and causing the steering pair gear to rotate accordingly.

[0010] The vertical conveying device includes a vertical conveying chain, a fixed base, a vertical control clutch device, and a vertical conveying assembly. When its translation plate moves to the designated position, the main drive shaft of the vertical conveying device rotates, driving its driving gear, transmission chain, and driven gear to rotate, thereby causing its auxiliary drive shaft to drive the auxiliary transmission gear to rotate.

[0011] The vertical conveying assembly includes a chain channel, chain clamps, a vertical conveying chain, and a vertical conveying control device. The chain clamps are used to fix the plastic drainage board in place. The bottom of the drill bit assembly is equipped with a pressure plate rod, an arrowhead tip, and an iron chain.

[0012] Furthermore, steel plates are installed around the mixing drill, and each steel plate is connected to a fixed base.

[0013] Furthermore, the drill bit assembly is equipped with a water outlet pipe, which is fixed inside the drill rod. Two connecting pipes extend from the bottom to the outside of the drill rod and are connected to the water jet outlet.

[0014] Furthermore, the mixing drill and the spring damping vibration damper are fixed on the fixed top plate, and the bottom of the spring damping vibration damper is connected to the fixed base and fixed to the frame to form an integral whole.

[0015] Furthermore, the horizontal control clutch device drives the clutch secondary gear, transmission chain, and clutch main gear to rotate by rotating the steering secondary gear. The rotation of the clutch main gear drives the translation gear to move horizontally.

[0016] Furthermore, the vertical clutch device is fixed on the vertical transmission assembly. The clutch secondary gear achieves contact and separation with the secondary transmission gear through an electromagnetic coil. When the secondary transmission gear contacts the clutch secondary gear, the clutch main gear and the transmission chain rotate simultaneously, driving the chain gear, which in turn causes the vertical transmission chain to move upward, allowing the plastic drainage plate to be conveyed to the top of the drill rod.

[0017] Furthermore, the vertical transmission control clutch device includes a clutch bracket, an electromagnetic coil, an iron block, a secondary transmission gear, a clutch secondary gear, a clutch main gear, a transmission chain, a spring fixing device, a spring, and a limit plate. When the electromagnetic coil is energized, the secondary transmission gear and the clutch secondary gear are brought into contact. The rotation of the secondary transmission gear drives the clutch secondary gear and the transmission chain to drive the clutch main gear to rotate.

[0018] Furthermore, the total length of the chain channel must be greater than the length of the vertical transmission chain.

[0019] Furthermore, the stirring fan blades include inner stirring teeth and several outer blades, with the blades fixed in a specific position by a limiting device.

[0020] Furthermore, a drill pipe outer sleeve ring is provided on the outside of the drill pipe.

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] This utility model provides a multifunctional plastic drainage board insertion machine for foundation treatment, capable of construction in relatively hard strata. It can transport plastic drainage boards from the ground to the top of the drill rod, and further to a designated position at the bottom of the drill rod, reducing the need for workers to climb to heights and avoiding the risks of working at heights. The machine features independent motor control for the horizontal movement of the translation board and the horizontal and vertical transport of the drainage boards. The drill bit device functions as a pile tip for soil squeezing, water jet cutting, and soil mixing, improving the efficiency of drill rod advancement. Simultaneously, the sealed drill bit device avoids the disadvantages of drainage board retrieval and the risk of drill rod blockage during construction, enhancing the construction efficiency of drainage boards. With a high degree of automation, it improves the construction efficiency of plastic drainage boards in complex strata, resulting in significant economic benefits. Attached Figure Description

[0045] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] A multi-functional foundation treatment plastic drainage board insertion machine, such as Figures 1 to 18 As shown, it includes a vibration damping and stirring transmission device 1, a horizontal moving device 2, a vertical conveying device 3, a vertical conveying assembly 4, a clutch device 5, a drill bit device 6, a plastic drainage board 6-5, a vibratory hammer 7, a moving auxiliary track 7-1, a translation plate 8, a main drive shaft 9, a bottom frame 10, a traveling bracket 10-1, a high-pressure grouting pump 11-1, a high-pressure water pipe 11-2, a water inlet pipe 11-3, a motor 12, a reducer 12-1, a winch 13, a fixed pulley 13-1, a wire rope 13-2, an operating room 14, a steel bracket 15, a support rod 16, and a traveling device 17.

[0047] The vibration damping and mixing transmission device 1 is located at the top of the equipment. Its main function is to transmit the power of the mixing drill to the mixing blades at the bottom of the drill rod. The rotation of the mixing blades loosens the soil below the ground. The vibration damping and mixing transmission device 1 includes a spring damper 1-1, a main drive shaft 1-2, a fixed base 1-3, a drive gear 1-4, a driven gear 1-5, a secondary drive shaft 1-6, a mixing drill 1-7, a driven gear 1-8, a frame 1-9, a mixing gear 1-10, a fixed top plate 1-11, a drill rod 1-12, and a steel plate 1-13.

[0048] The mixing drill 1-7 and the spring-damped vibration damper 1-1 are fixed to the fixed top plate. The bottom of the spring-damped vibration damper 1-1 is connected to the fixed base 1-3 and fixed to the frame 1-9 to form a whole. Steel plates 1-12 are installed around the mixing drill 1-7 to restrict the horizontal movement of the mixing motor 1-7. The steel plates 1-13 are connected to the fixed base 1-3. When the mixing drill 1-7 is powered on, the main drive shaft 1-2 rotates, driving the drive gear 1-4, the driven gear 1-8, and the auxiliary drive shaft 1-6 to rotate. The auxiliary drive shaft 1-6 drives the driven gear 1-5 to rotate, thereby rotating the mixing gear 1-10, and the mixing fan blades at the bottom of the drill rod can then rotate.

[0049] The top of the frame 1-9 is connected to the vibratory hammer 7. The vibratory hammer 7 vibrates and strikes, causing the drill rod 1-12 to drill downwards. The spring damping shock absorber 1-1 can weaken the vibration of the vibratory hammer 7, making the mixing drill 1-7 rotate more stably.

[0050] The horizontal moving device 2 is located on the lower left side of the machine and its purpose is to move the plastic drainage plate horizontally to a designated position. The horizontal moving device 2 includes a fixed bracket 2-1, a reversing gear 2-2, a translation gear 2-3, a clutch device 2-4, a transmission chain 2-5, a fixed bracket 2-6, a clutch fixed bracket 2-7, a forward gear 2-8, a steering main gear 2-9, a steering secondary gear 2-10, a clutch secondary gear 2-11, a transmission chain 2-12, a clutch main gear 2-13, a fixed base 2-14, a turbine rotating shaft 2-15, a turbine rotating gear 2-16, a roller 2-17, a translation plate 8, and a main drive shaft 9. The horizontal moving device 2 drives the turbine rotating shaft 2-15 to rotate via the main drive shaft 9, which in turn rotates the turbine rotating gear 2-16, causing the steering main gear 2-9 to rotate. This, in turn, causes the forward gear 2-8 and the steering main gear 2-9 to rotate, and the steering secondary gear 2-10 to rotate accordingly.

[0051] The horizontal control clutch device 2-4 rotates via the steering auxiliary gear 2-10, which in turn drives the clutch auxiliary gear 2-11, the transmission chain 2-12, and the clutch main gear 2-13 to rotate. The rotation of the clutch main gear 2-13 drives the translation gear 2-19 to move horizontally. Preferably, the clutch auxiliary gear 2-11 of the two clutch devices 2-4 cannot be in contact with the steering auxiliary gear 2-10 at the same time, keeping one disengaged and the other engaged, or both disengaged simultaneously. One of the two clutch devices 2-4 controls the translation plate 8 to move to the left, and the other controls the translation plate 8 to move to the right.

[0052] The vertical conveying device 3 is located in the lower middle position of the machine. Its purpose is to vertically deliver the plastic drainage board to the top of the drill rod and then convey it from the top to the bottom of the drill bit. The vertical conveying device 3 includes a rectangular opening 3-1, a vertical conveying chain 3-2, a clutch main gear 3-3, a transmission chain 3-4, a driven gear 3-5, a secondary transmission gear 3-6, a clutch secondary gear 3-7, a chain gear 3-8, a fixed base 3-9, a driven gear 3-10, a fixed bracket 3-11, a secondary transmission shaft 3-12, a clutch device 3-13, a vertical conveying assembly 4, a translation plate 8, and a main transmission shaft 9. The vertical conveying assembly 4 in the vertical conveying device 3 is fixed on the translation plate 8. When the translation plate 8 moves to the designated position, the main transmission shaft 9 rotates, driving the drive gear 3-10, the transmission chain 3-7, and the driven gear 3-5 to rotate, thereby causing the secondary transmission shaft 3-12 to drive the secondary transmission gear 3-6 to rotate.

[0053] The vertical control clutch device 3-13 is fixed to the vertical transmission assembly 4. The clutch secondary gear 3-7 can contact and disengage with the secondary transmission gear 3-6 through the electromagnetic coil inside the clutch device 3-13. When the secondary transmission gear 3-6 contacts the clutch secondary gear 3-7, the clutch main gear 3-3 and the transmission chain 3-4 rotate simultaneously, driving the chain gear 3-8, which further moves the vertical transmission chain 3-2 upward, allowing the plastic drainage plate to be conveyed to the top of the drill rod. To move the transmission chain 3-2 downward, the motor 12 can be set to reverse.

[0054] The vertical conveying assembly 4 is fixed to the translation plate. Its internal components include a chain channel 4-1, a fixed bracket 4-2, a clutch device 3-13, a chain clamp 4-4, a plastic drainage plate 4-5, a vertical conveying chain 3-2, a conveying chain 3-4, a secondary transmission gear 3-6, a clutch secondary gear 3-7, and a chain gear 3-8. The vertical conveying chain 3-2, located within the chain channel 4-1, can move both horizontally and vertically. The total length of the chain channel 4-1 is greater than the length of the vertical conveying chain 3-2. The chain clamp 4-4 holds the plastic drainage plate 3-2 in place. When the plastic drainage plate 3-2 reaches the bottom of the drill pipe, after a certain length is reserved, the drainage plate is cut, and the chain clamp 4-4 is retracted back into the chain channel 4-1. The chain clamp 4-4 clamps the plastic drainage plate 6-5 and secures it with bolts 4-4-1.

[0055] The vertical transmission control clutch device 5 includes a clutch bracket 5-1, an electromagnetic coil 5-2, an iron block 5-3, a secondary transmission gear 5-4, a clutch secondary gear 5-5, a clutch main gear 5-6, a transmission chain 5-7, a spring fixing device 5-8, a spring 5-9, and a limiting plate 5-10. The preferred clutch device 5 primarily uses the electromagnetic coil 5-2 to energize the secondary transmission gear 5-4 and the clutch secondary gear 5-5, causing the secondary transmission gear 5-4 to rotate, which in turn drives the clutch main gear 5-6 to rotate via the clutch secondary gear 5-5 and the transmission chain 5-7, thereby achieving the rotation of the relevant components.

[0056] The clutch device 5 has two implementation methods. One method involves separating the secondary transmission gear 5-4 and the clutch secondary gear 5-5 through the elasticity of the spring 5-9 when the electromagnetic coil 5-2 is not energized, further stopping the rotation of the clutch main gear 5-6. This method is suitable for horizontal control clutch devices. The other method replaces the spring 5-9 with a limiting plate 5-10. When the electromagnetic coil 5-2 is not energized, the clutch secondary gear 5-5 falls under its own weight, disengaging from the secondary transmission gear 5-4. Combined with the limiting plate 5-10, the clutch secondary gear 5-5 is restricted to a designated position. This method is suitable for vertical transmission components.

[0057] The drill bit assembly 6 is located at the bottom of the drill rod. Its main purpose is to drive the plastic drainage board to a specified elevation below the ground surface. This drill bit has the functions of stirring, water jet cutting, and pile tip soil squeezing. It is used in combination depending on the soil drilling conditions. The specific structure includes a limiting device 6-1, an iron chain 6-2, a pressure plate rod 6-3, an arrow pile tip 6-4, a plastic drainage board 6-5, a water outlet pipe 6-6, blades 6-7, steel balls 6-8, a water jet outlet 6-9, a drill rod 6-10, a stirring gear 6-11, a driven gear 6-12, a pre-drilled hole 6-13, and a drill rod outer ring 6-14. The blades 6-7 are a ring-shaped device with four blades on the outer side and stirring teeth 6-11 on the inner side. The blades 6-7 are fixed in a specified position by the limiting device 6-1 and can rotate, but cannot move up and down. A steel ball is located between the limiting device 6-1 and the blades 6-7 to facilitate the rotation of the blades. The driven gear 6-12 at the top rotates, driving the mixing gear 6-11 to rotate, which in turn causes the blades 6-7 to rotate, cutting the soil. The drill rod outer ring 6-14 is located outside the drill rod 6-10 and is used to protect the rotation of the driven gear 6-12.

[0058] The bottom of the drill bit device 6 is equipped with a pressure plate rod 6-3, an arrowhead tip 6-4, and an iron chain 6-2. Before drilling, the pressure plate rod 6-3 is placed in the designated groove, the drainage board is pulled out and inserted into the reserved hole 6-13, and the arrowhead tip 6-4 is further installed in the designated position before drilling begins. When the arrowhead tip 6-4 reaches the designed drilling elevation, the top vibratory hammer stops vibrating, and the drill rod 6-10 is lifted. At this time, the arrowhead tip 6-4 separates from the drill rod, and the pressure plate rod 6-3 is squeezed by the surrounding soil layer and temporarily remains in the designated position. As the drill rod 6-10 is lifted, the plastic drainage board 6-5 is pulled out, unfolded, and left in the designated position. As the drill rod 6-10 is further lifted, the pressure plate rod 6-3 and the arrowhead tip 6-4 are lifted to the ground by the tension of the chain 6-2.

[0059] The drill bit assembly 6 includes a water outlet pipe 6-6 and a water jet outlet 6-9. The water outlet pipe 6-6 is fixed inside the drill rod 6-10, with two pipes leading out from the bottom to the outside of the drill rod, connecting to the water jet outlet 6-9. When the drill rod 6-10 drills into a dense soil layer, the high-pressure grouting pump can be turned on to pump water to the water outlet pipe 6-6, which, combined with the water jet outlet 6-9, allows for high-pressure water jet cutting of the soil at the bottom of the drill rod. It is important to ensure that the entire drill rod body, including the water outlet pipe 6-6, is sealed and leak-proof.

[0060] The construction method is as follows:

[0061] Step 1: Before construction, the site needs to be leveled and compacted to ensure the machine can move normally. First, drive the machine to the location where the drainage board needs to be installed. Use the winch 13 to lift the vibratory hammer 7 and drill rod 6-10 to the top of the machine for assembly. After installation, start the motor 12. The reducer 12-1 will reduce the motor speed. The clutch 2-4-1 in the horizontal moving device 2 will be activated. Move the translation plate 8 to move the vertical conveying component 4 towards the center, aligning it with the drill rod 6-10. Then, close the clutch 2-4-1. Next, secure the head of the plastic drainage plate 6-5 to the chain clamp 4-4, activate the clutch device 4-3, and transport the conveyor chain 3-2 and the plastic drainage plate 6-5 to the drainage plate transport inlet at the top of the drill rod. The drainage plate and conveyor chain enter from the inlet and are delivered to the bottom of the drill bit at the bottom of the drill rod 6-10. Separate the head of the plastic drainage plate 6-5 from the chain clamp 4-4, close the clutch device 4-3, reverse the motor 12, activate the clutch device 4-3 again, retract the conveyor chain 3-2 into the vertical conveyor assembly 4, and then close the clutch device 4-3. Finally, set the motor 12 to forward rotation, activate the clutch device 2-4-2, and after the translation plate 8 moves back to its original position, close the clutch device 2-4-2, and the motor 12 will shut off. At this point, the drainage plate installation is complete.

[0062] Step Two: Place the pressure plate rod 6-3 into the designated groove of the drill bit device 6, and simultaneously pull out the plastic drainage board 6-5 and place it into the designated reserved slot. Embed the tail of the arrowhead pile tip 6-4, forming a closed unit with the drill bit device 6. The arrowhead pile tip 6-4 will detach freely under gravity when there is no upward pressure. After determining the construction location, start the winch 13 to slowly lower the vibratory hammer 7 and drill rod 6-10. Once the drill bit device 6 contacts the soil layer, turn off the winch 13. At this point, the preliminary work for installing the drainage board is complete.

[0063] Step 3: Start the vibratory hammer 7 to apply the drainage board. When the drilling reaches a harder soil layer and the drill rod is difficult to advance, start the mixing drill 1-7. The main drive shaft 1-2, drive gear 1-4, driven gear 1-8, auxiliary drive shaft 1-6, secondary driven gear 1-5, and mixing gear 1-10 work together to cut and mix the soil layer at the bottom of the drill rod. The spring damping shock absorber 1-1 reduces the vibration from the vibratory hammer 7, keeping the mixing drill 1-7 in a relatively stable position. Next, turn on the high-pressure grouting pump 11-1. Water is drawn in through the inlet pipe 11-3 and expelled through the outlet pipe 6-6 and water jet outlet 6-9, cutting the soil layer at the bottom of the drill rod with water jets. Water also has a lubricating effect; during drilling, the water flow softens the soil, lubricates the sidewalls, reduces the frictional resistance between the soil layer and the drill rod, assists the drilling rod 6-10 in advancing, and weakens the soil squeezing effect when lifting the drill rod. Combining the triple action of the three-in-one arrowhead pile tip, water jet, and mixing, the drilling speed of the drill rod in harder soil layers can be accelerated. Adjustments can be made according to the actual soil hardness. When the soil is soft, the high-pressure grouting pump and mixing drill can be left off, allowing direct drilling. Various combinations are also possible, such as pile tip with water jet, pile tip with mixing, and pile tip with both water jet and mixing.

[0064] Step 4: When drill rod 6-10 reaches the designed depth, turn off vibratory hammer 7, mixing drill 1-7, and high-pressure grouting pump 11-1, and turn on winch 13 to lift vibratory hammer 7 and mixing drill 1-7. In drill bit device 6 at the bottom of drill rod, arrow tip 6-4 disengages, and pressure plate rod 6-3 is temporarily fixed in its original position by the surrounding soil layer. At the same time, it presses down on plastic drainage board 6-5 and pulls it out, leaving plastic drainage board 6-5 at the bottom of drill rod. As drill rod 6-10 is lifted, arrow tip 6-4 and pressure plate rod 6-3 are brought out of the soil layer to the ground by the tension of chain 6-2. At this time, the construction of this plastic drainage board is completed. Move the drill to the construction position of the next drainage board and carry out the construction of the next drainage board. Repeat the procedures of steps one to four.

[0065] This utility model features a reasonable structural design. The vibration-damping mixing transmission device is located at the lower left of the machine, while the horizontal moving device, vertical conveying device, moving auxiliary track, and vertical conveying support are located at the lower middle of the machine. The drill bit device is located at the bottom of the drill rod. Using the multifunctional foundation treatment plastic drainage board insertion machine provided by this utility model, construction can be carried out in relatively hard strata. It can convey plastic drainage boards from the ground to the top of the drill rod, and further to a designated position at the bottom of the drill rod, reducing the need for workers to climb to heights and avoiding the risks of working at heights. The horizontal movement of the translation plate and the horizontal and vertical conveying of the drainage boards are independently controlled by a motor. The drill bit device has the functions of pile tip soil squeezing, water jet cutting, and soil mixing, improving the efficiency of drill rod advance. At the same time, the drill bit device is sealed, avoiding the disadvantages of drainage board retracement and the risk of drill rod blockage during construction, improving the construction efficiency of drainage boards.
