Description

Technical Field

[0001] The invention relates to the technical field of stratum settlement control devices, and in particular to a rapid-setting settlement control device for soft-hard uneven composite strata and a control method thereof. Background Art

[0002] Composite strata refer to strata composed of two or more different strata within the excavation section of underground engineering and in the direction of excavation extension, and the geotechnical mechanics, engineering geology and hydrogeology of these strata are very different. When the shield passes through the composite strata with soft upper and hard lower, the shield posture is difficult to control, and the degree of cutting of the rock and soil in front by the cutterhead is inconsistent, which can easily cause large stratum disturbance and trigger large-scale and large-area surface settlement. In addition, the spatial combination of composite strata is changeable, the distribution law of surface settlement is more complicated, and the surface settlement is difficult to be targeted and controlled, making it difficult to ensure the safety of shield construction and the safety of existing structures above the shield. When faced with such strata with large differences in hardness, slurry that can diffuse into the pores of the stratum can be injected into the stratum to improve the uneven hardness of the stratum, so that the properties of the strata on the excavation surface are as close as possible, so as to prevent the shield posture from being difficult to control in the uneven hardness stratum, causing stratum settlement and affecting construction safety.

[0003] The existing grouting device has the following problems:

[0004] (1) When the existing grouting device is performing grouting operations from top to bottom, it is necessary to wait until the grout is completely solidified before the grouting operation at another location can be carried out, resulting in poor construction continuity.

[0005] (2) The existing slurry grouting device needs to first drill a hole in the composite formation by a drilling machine, and then use a slurry grouting machine to inject grout into the hole. Due to the poor fluidity of the slurry, the injected slurry is difficult to completely reach the bottom of the hole, resulting in a poor solidification effect on the composite formation.

[0006] Therefore, there is an urgent need to design a rapid setting settlement control device and a control method for soft and hard uneven composite strata that can solve the above problems. Summary of the invention

[0018] Preferably, a control method for a rapid setting settlement control device for a soft-hard uneven composite formation comprises the following steps:

[0019] S1: The hydraulic mechanical arm drives the spiral drill bit to move to an appropriate position, and the rotating motor drives the sliding plate to move through the driving chain, so that the gear ring is engaged with the connecting gear. After that, the driving motor drives the guide pipe to rotate through the driving gear, so that multiple baffles are unfolded to allow the spiral drill bit to pass through;

[0020] S2: The spiral drill bit drills holes in the softer strata of the composite strata under the action of the driving motor, and gradually penetrates into the strata under the drive of the sliding plate;

[0021] S3: When the spiral drill bit reaches the appropriate depth, the delivery pump injects slurry into the guide pipe, and the slurry is discharged into the drilled hole through the guide hole on the guide pipe, and gradually withdraws from the hole under the action of the sliding plate;

[0023] S5: The discharge holes on the multiple groups of baffles inject the quick-setting agent in the quick-setting agent storage box into the outlet of the hole, completely closing the hole to prevent the unsolidified slurry from flowing out. Then the multiple groups of baffles are unfolded and separated from the quick-setting agent, and the above process is quickly repeated to proceed to the next step.

[0024] The beneficial effects of the present invention are:

[0025] In order to solve the problems existing in the prior art, the present invention provides a rapid-setting settlement control device for soft and hard uneven composite strata and a control method thereof, which extends into the stratum to carry out sufficient grouting and solidifies the grouting step by step, effectively improving the characteristics of the soft and hard uneven strata, making the stratum properties of the excavation surface as similar as possible, effectively solving the problem of stratum settlement caused by the difficulty in controlling the shield posture in the soft and hard uneven strata, and improving construction safety.

[0026] First, in the present invention, under the action of the quick-setting component, the hole can be quickly closed during the bottom-up drilling and grouting process to prevent the unsolidified slurry from flowing out, so that the construction process can be carried out continuously. Specifically, multiple groups of baffles are closed at the same time to block and seal the unsolidified slurry. After that, the discharge holes on the multiple groups of baffles inject the quick-setting agent in the quick-setting agent storage box into the outlet of the hole. The quick-setting agent quickly solidifies and completely closes the hole to prevent the unsolidified slurry from flowing out. After that, the multiple groups of baffles are unfolded and separated from the quick-setting agent to prevent the baffles from sticking to the quick-setting agent. The hydraulic mechanical arm drives the drill bit to move, and the next step of drilling and grouting operation can be carried out quickly, so that the construction can be carried out continuously.

[0027] Secondly, in the present invention, under the joint action of the drilling assembly and the slurry conveying assembly, the drilling and injection processes of the composite formation can be carried out simultaneously, so that the slurry with poor fluidity can completely reach the bottom of the hole, ensuring the curing effect of the composite formation. Specifically, the rotating motor drives the chain to rotate along the two sets of flywheels through the first synchronous belt to drive the sliding plate to move along the slide rail. When the spiral drill bit reaches the bottom of the hole, the conveying pump injects slurry into the guide pipe, and the sliding plate drives the rotating pipe to gradually withdraw from the hole, so that the slurry is fully filled in the hole, ensuring the curing effect of the composite formation and preventing the composite formation from excessive settlement.

[0028] Third, in the present invention, the rotating rod drives the driving gear to rotate under the driving action of the stirring motor. When the driving gear rotates, it drives multiple groups of passive gears to rotate together, thereby driving the rotating rod to rotate. Since each group of rotating rods is rotatably connected to the connecting plate, the rotating rod will rotate along the rotating rod with the rotating rod as the center of the circle while rotating. Therefore, the stirring rod located on the outer wall of the rotating rod can not only rotate by itself, but also rotate along the rotating rod, so as to continuously stir the slurry in the stirring tank, so that the slurry is fully mixed and the slurry is prevented from solidifying.

[0029] Fourthly, in the present invention, the sealing rubber layer can seal the gaps between the multiple groups of baffles, and the unsolidified slurry can be blocked by the multiple groups of closed baffles to prevent the slurry from flowing out;

[0030] Fifth, in the present invention, after the driving motor is decelerated by the reducer, the driving gear and the driven gear mesh together to drive the spiral drill bit to rotate, and the composite formation is drilled. The delivery pump injects slurry into the guide pipe, and the slurry is discharged to the bottom of the drilled hole through the guide hole on the guide pipe. The anti-backflow block on the guide pipe can effectively prevent the slurry from backflowing and overflowing in the process of the guide pipe gradually withdrawing from the hole.

[0031] Sixth, in the present invention, the gear ring on the rotating tube moves with the sliding plate, so that the gear ring is engaged with the connecting gear, and the connecting gear drives the transmission shaft to rotate through the second synchronous belt, and the transmission shaft continues to drive the rotating disk to rotate through the transmission gear, so that multiple groups of baffles are closed or unfolded at the same time.

[0065] Working principle: After the driving motor 18 is decelerated by the reducer 19, the spiral drill bit 28 is driven to rotate through the meshing action of the driving gear 21 and the driven gear 20 to drill the composite formation. After that, the delivery pump 40 injects slurry into the guide pipe 17 and discharges it to the bottom of the drilled hole through the guide hole 29 on the guide pipe 17.

[0066] When driven by the stirring motor 39, the rotating rod 52 will drive the driving gear 50 to rotate. When the driving gear 50 rotates, it will drive multiple groups of passive gears 49 to rotate together, thereby driving the rotating rod 43 to rotate. Since each group of rotating rods 43 is rotatably connected to the connecting plate 45, when the rotating rod 43 rotates, it will rotate along the rotating rod 52 with the rotating rod 52 as the center of the circle, so that the stirring rod 44 located on the outer wall of the rotating rod 43 can not only rotate by itself, but also rotate along the rotating rod 52, so as to continuously stir the slurry in the stirring tank 2, so that the slurry is fully mixed and the slurry is prevented from solidifying.

[0067] The rotating motor 15 drives the chain 10 to rotate along the two sets of flywheels 22 through the first synchronous belt 6 to drive the sliding plate 14 to move along the slide rail 3. When the guide hole 29 injects slurry into the bottom of the hole, the sliding plate 14 drives the rotating tube to gradually withdraw from the hole, so that the slurry is fully filled in the hole, thereby ensuring the solidification effect on the composite formation and preventing excessive settlement of the composite formation.

[0068] When the slurry is poured, the gear ring 46 on the rotating tube moves with the sliding plate 14, so that the gear ring 46 engages with the connecting gear 47, and the connecting gear 47 drives the transmission shaft 23 to rotate through the second synchronous belt 48. The transmission shaft 23 continues to drive the rotating disk 31 to rotate through the transmission gear 26. When the rotating disk 31 rotates, the sliding rod 51 is driven by the push rod 34 to move along the arc-shaped slide groove 35, driving the baffle 36 to rotate, controlling multiple groups of baffles 36 to close at the same time, thereby shielding and sealing the unsolidified slurry to prevent the slurry from flowing out.

[0069] Afterwards, the discharge holes 37 on the multiple groups of baffles 36 inject the quick-setting agent in the quick-setting agent storage box 13 into the outlet of the hole, and the quick-setting agent solidifies quickly to completely seal the hole to prevent the unsolidified slurry from flowing out. Then, the multiple groups of baffles 36 are unfolded and separated from the quick-setting agent to prevent the baffles 36 from sticking to the quick-setting agent. The hydraulic mechanical arm 4 drives the drill bit to move, and the next step of drilling and grouting operation can be carried out quickly, so that the construction can continue.

[0070] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
