Description

Technical Field

[0001] This invention relates to the fields of building engineering and underground engineering technology, and in particular to apparatus and methods for underground caisson construction. Background Technology

[0002] With the continuous increase in urban infrastructure construction and large-scale engineering projects, caissons, as an important foundation form, are widely used in various structures such as bridges, subways, and deep foundation pits. The high overall rigidity, stability, and load-bearing capacity of caissons make them an ideal choice for bearing heavy loads and resisting water level changes. However, caissons often face several technical challenges during the sinking process. These include difficulties in sinking, uneven sinking, passive sinking methods, large earthwork volumes, and significant impacts on the surrounding environment, which seriously affect sinking efficiency and construction safety.

[0003] Existing caisson sinking technologies mainly rely on methods such as mud drag reduction, gas-liquid drag reduction, and jacks or anchor bolts for force application. While each method has its advantages, it also has some shortcomings. For example, Chinese patent CN103088837A discloses a mud drag reduction and sinking aid device for caisson sinking construction. This device reduces the side friction resistance during caisson sinking by injecting thixotropic mud through pre-embedded grouting pipes within the caisson wall. Although this method effectively reduces the side friction resistance during caisson sinking, it fails to fully consider the more critical end resistance issue during the caisson sinking process. Chinese patent CN117868192A discloses a coaxial nested multi-segment caisson structure and a drag-reducing and sinking-aiding construction method for expansive soil strata. This method reduces the caisson resistance through a gas-liquid drag-reducing system (injecting gas, water, or mud) and a centering and limiting drag-reducing ball. It effectively reduces the side resistance of the caisson in expansive soil strata by utilizing the synergistic effect of the coaxial nested structure, the gas-liquid drag-reducing system, and the centering and limiting drag-reducing ball, thereby improving construction efficiency and reducing construction difficulty. However, the gas-liquid drag-reducing system has high requirements for equipment sealing and requires a high level of technical expertise from construction personnel. Furthermore, the device does not integrate a drainage function, which increases the amount of underwater excavation work and limits construction efficiency. Chinese patent CN115710924A discloses a caisson construction method and caisson structure. This method uses jacks and anchor bolts to mechanically pull the sidewalls and fixed points along the sinking direction of the caisson box, thereby overcoming end resistance and achieving caisson sinking. However, the use of anchor bolts leads to a longer construction period, and complex geological conditions can affect the effectiveness of the anchor bolts. The removal and sealing of the anchor bolts after the caisson bottom is also complex; improper handling may affect waterproofing and structural stability. Chinese patent CN222436356U discloses a quarrying device for a vertical shaft excavator. This device separates slag through two-stage screening and a quarry box, effectively avoiding equipment failure and improving excavation efficiency and reliability. However, this device requires excavating the central soil simultaneously with caisson construction, significantly increasing the initial earthwork volume, potentially causing ground subsidence, or impacting the surrounding environment due to groundwater level fluctuations.

[0004] Key technologies in caisson construction include: minimizing end and sidewall resistance to ensure smooth sinking; maintaining uniform sinking of the caisson wall to ensure structural stability; and minimizing underwater excavation work, mud discharge and treatment, and impact on the surrounding environment. Based on the above analysis, existing patented technologies all have room for improvement. Utility Model Content

[0005] In view of the shortcomings of existing technologies in tunneling caisson construction, this utility model provides a wall-mounted rotary drilling active sinking caisson device, which overcomes the problems of passive sinking, large soil disturbance, uneven sinking, displacement and overturning in traditional caisson construction. At the same time, the device adopts a miniaturized, detachable modular structure, which can be reused in similar projects. The core advantage of this device is that it actively removes the end-bearing resistance soil in front of the cutting edge through annular cutting, transforming the traditional caisson's 'passive sinking' that relies on its own weight to overcome huge resistance into 'active and controllable sinking' after the resistance is greatly reduced, fundamentally solving the sinking difficulties and sudden sinking risks.

[0006] The technical solution adopted in this utility model is as follows: A wall-mounted rotary drilling active sinking caisson device, installed on the caisson shaft, includes: The track module is fixed to the inner wall of the caisson shaft. A traveling motor module is mounted on the track module and travels along the track module; The cutting blade module is rotatably mounted on the travel motor module; A cutting drive module, mounted on the travel motor module, drives the cutting blade module to perform cutting. The mud inlet and outlet module includes a mud inlet pipe, a mud outlet pipe, and a circulating mud tank. The mud inlet pipe is used to inject water or mud, the mud outlet pipe is used to discharge excess mud, and the circulating mud tank is used to provide circulating mud. The caisson module is connected to the caisson shaft, allowing it to sink.

[0007] Optionally, the track module includes a steel ring beam for the inner wall of the caisson and an I-beam track, with a pair of oppositely arranged I-beam tracks installed between two vertically arranged steel ring beams for the inner wall of the caisson. It also includes a pre-reserved disassembly track module, which has a disassembly notch for detachable installation. The pre-reserved disassembly track module includes a pre-reserved disassembly track, a pre-reserved tenon, and a pre-reserved mortise. The pre-reserved disassembly track is a T-shaped track composed of a steel ring beam on the inner wall of the caisson and an I-beam track, with pre-reserved mortise grooves at both ends. Pre-reserved tenons are fixedly installed at both ends of the disassembly notch, and pre-reserved mortise grooves that mate with the pre-reserved tenons are opened at both ends of the pre-reserved disassembly track. When the device needs to be installed or disassembled, the pre-reserved disassembly track is lifted vertically to separate the pre-reserved mortise grooves from the pre-reserved tenons, thus forming a disassembly notch, from which the device can be installed or disassembled.

[0008] Optionally, the travel motor module includes a travel motor, a travel motor bracket, and travel pulleys. The travel motor is mounted on the travel motor bracket, and the travel pulleys are mounted on the rotating shaft of the travel motor and are secured to the track module.

[0009] Optionally, the travel motor module further includes a limiter, which is disposed on the travel motor bracket. The limiter is used to restrict the blade shaft of the cutting blade module so that the blade shaft always remains vertical.

[0010] Optionally, the cutting drive module includes a cutting motor, a cutting motor bracket, a drive gear, and a driven gear. The cutting motor is mounted on the cutting motor bracket, the drive gear is mounted on the cutting motor, the drive gear and the driven gear mesh, and the driven gear is connected to the blade shaft of the cutting blade module.

[0011] Optionally, the cutting blade module includes a blade shaft and a cutting blade, with the cutting blade fixed to the lower end of the blade shaft.

[0012] Optionally, the mud inlet and outlet module also includes pipe connectors and clamps. The pipe connectors are used to connect the mud inlet pipe and the blade shaft of the cutting blade module. The mud inlet pipe and the discharge pipe are fixed by the clamps.

[0013] Optionally, the caisson module includes a wire rope, pulleys, guide walls, and a winch. The pulleys are arranged on the guide walls, one end of the wire rope is connected to the winch, and the other end is connected to the caisson shaft. The pulleys guide the wire rope in the middle.

[0014] Optionally, four caisson modules are evenly distributed along the circumference.

[0015] Optionally, the caisson module further includes a tension sensor, a computer, and a data acquisition card; the tension sensor is connected to the steel wire rope; the tension sensor is electrically connected to the data acquisition card; the data acquisition card is electrically connected to the computer; the data acquisition card is used to collect the tension data from the tension sensor and transmit it to the computer.

[0016] The technical solutions provided by the embodiments of this application may include the following beneficial effects: 1. A central soil layer is reserved for the caisson, allowing for underwater construction. Maintaining the original stress state of the surrounding area enhances the stability of the caisson wall soil, effectively controls surface settlement, shortens the construction period, improves overall construction efficiency, and reduces construction costs. This technique also reduces construction vibration, noise, and dust, significantly minimizing environmental impact on adjacent buildings, underground pipelines, and sensitive areas.

[0017] 2. Active and uniform sinking is achieved through mechanical cutting. This transforms the passive process of overcoming huge end resistance into an active process of eliminating end resistance. Compared with traditional methods, it has better construction controllability, precisely controls sinking speed and cutting depth, and the rotating blade can effectively loosen the bottom soil, reduce disturbance to the surrounding soil, avoid the risk of sudden sinking or deflection, and leave a central soil mass to form natural support and maintain the stability of the soil around the well.

[0018] 3. It adopts a miniaturized, detachable modular structure. It adapts to the construction needs of narrow urban spaces, facilitates transportation, installation and reuse, can be quickly adjusted according to different caisson diameters, and can be hoisted and transferred as a whole after construction, significantly improving resource utilization efficiency.

[0019] 4. Through the coordinated operation of the water inlet pipe and the slurry outlet pipe, lubricating mud is formed, and the mud flow and pressure are dynamically adjusted to effectively control the pressure balance of the well wall, reduce the lateral earth pressure on the caisson, and avoid cracking of the well wall caused by local stress concentration. The circulating mud pool excavated in the soil at the center of the caisson can realize the on-site treatment and recycling of mud, saving space and reducing costs.

[0034] refer to Figures 1 to 9This application provides a wall-mounted rotary drilling active sinking caisson device, installed on a caisson shaft 1, comprising: a track module 2, a travel motor module 3, a cutting blade module 5, a cutting drive module 4, a mud inlet / outlet module 6, and a caisson module 7. The track module 2 is fixed to the inner wall of the caisson shaft 1; the travel motor module 3 is mounted on the track module 2 and travels along the track module 2; the cutting blade module 5 is rotatably mounted on the travel motor module 3; the cutting drive module 4 is mounted on the travel motor module 3 and drives the cutting blade module 5 to perform cutting; the mud inlet / outlet module 6 includes a mud inlet pipe 61, a mud outlet pipe 62, and a circulating mud tank 65. The mud inlet pipe 61 is used to inject water or mud, the mud outlet pipe 62 is used to discharge excess mud, and the circulating mud tank 65 is used to provide circulating mud; the caisson module 7 is connected to the caisson shaft 1 to sink it.

[0035] The following provides a detailed explanation of each component and its working principle.

[0036] The caisson shaft 1 serves as the installation carrier for the entire device, providing the foundation for the track module 2. During construction, the inner wall steel ring beam 21 and I-beam track 22 are precisely welded onto the inner wall of the caisson to form the device's running track system. The track is made of high-strength steel, and the welding quality meets relevant specifications.

[0037] The track module 2 includes a steel ring beam 21 for the inner wall of the caisson and an I-beam track 22. A pair of oppositely arranged I-beam tracks 22 are installed between two vertically arranged steel ring beams 21 for the inner wall of the caisson.

[0038] It also includes a pre-reserved disassembly track module 8, which has a disassembly notch for detachable installation. The pre-reserved disassembly track module 8 includes a pre-reserved disassembly track 81, a pre-reserved tenon 82, and a pre-reserved mortise 83. The pre-reserved disassembly track 81 is a T-shaped track integrally formed by the inner wall steel ring beam 21 of the caisson and the I-beam track 22, with pre-reserved mortise 83 at both ends. The pre-reserved tenon 82 is fixedly installed at both ends of the disassembly notch, and the pre-reserved mortise 83 that mates with the pre-reserved tenon 82 is opened at both ends of the pre-reserved disassembly track 81. When the device needs to be installed or disassembled, the pre-reserved tenon 82 on the pre-reserved disassembly track 81 is lifted from the pre-reserved mortise 83 to form a disassembly notch, and the device can be installed or disassembled from the disassembly notch. The reserved tenon 82 is part of the reserved disassembly track 81. The reserved tenon 82 is on the steel ring beam 21 of the inner wall of the caisson at the disassembly opening. The tenon and mortise connection structure forms a disassembly channel by lifting the tenon, thereby realizing the rapid installation and disassembly of the device.

[0039] The traveling motor module 3 includes a traveling motor 31, a traveling motor bracket 32, and a traveling pulley 34. The traveling motor 31 is mounted on the traveling motor bracket 32, and the traveling pulley 34 is mounted on the rotating shaft of the traveling motor 31. The traveling pulley 34 is engaged with the track module 2, that is, the traveling pulley 34 is engaged between a pair of I-beam rails 22 and rolls along the I-beam rails 22 to realize the directional movement of the device along the well wall.

[0040] The travel motor module 3 also includes a limiter 33, which is mounted on the travel motor bracket 32. The limiter 33 is used to restrict the blade shaft 51 of the cutting blade module 5, so that the blade shaft 51 always remains vertical. (The limiter 33 is a limiting seat with a vertical through hole fixed on the bracket. The blade shaft 51 passes through the through hole and is radially constrained by the side wall of the through hole, retaining only the degree of freedom of rotation around its own axis.)

[0041] The travel motor 31 can drive the travel pulley 34 to rotate via a precision reducer and a transmission shaft. The travel motor 31 can be frequency-controlled, and the travel speed can be precisely adjusted according to construction needs.

[0042] The cutting blade module 5 includes a blade shaft 51 and a cutting blade 52, with the cutting blade 52 fixed to the lower end of the blade shaft 51.

[0043] The cutting drive module 4 also includes a cutting motor 41, a cutting motor bracket 42, a drive gear 43, and a driven gear 44. The cutting motor 41 is mounted on the cutting motor bracket 42, and the drive gear 43 is mounted on the cutting motor 41. The drive gear 43 and the driven gear 44 mesh with each other. The driven gear 44 is connected to the blade shaft 51 of the cutting blade module 5 and drives the driven gear 44 to rotate through gear meshing.

[0044] When the device is in operation, the traveling motor 31 drives the traveling pulley 34 to move along the track, so that the entire device moves along the inner wall of the caisson. At the same time, the switching motor 41 drives the blade shaft 51 to rotate through gear transmission, driving the cutting blade 52 to cut the soil.

[0045] The mud inlet and outlet module 6 includes a mud inlet pipe 61, a mud outlet pipe 62, pipe connectors 63, clamps 64, and a circulating mud tank 65. The mud inlet pipe 61 injects water into the cutting area via the blade shaft 51, mixing it with the cutting soil to form mud; alternatively, mud can be injected directly. The mud outlet pipe 62 discharges excess mud, maintaining mud concentration balance within the well. The pipe connectors 63 ensure reliable pipe connections, and the clamps 64 fix the relative positions of the pipes. The circulating mud tank 65 provides circulating mud.

[0046] Without loss of generality, the mud inlet pipe 61 and the mud outlet pipe 62 can be connected to the corresponding mud inlet pump and mud outlet pump respectively to realize mud inlet and mud outlet.

[0047] The caisson module 7 includes a wire rope 71, a pulley 72, a guide wall 73, and a winch 77. In this embodiment, four sets of this module are symmetrically arranged along the guide wall. The installation relationship of these components is as follows: the winch 77 and the pulley 72 are both installed on the guide wall 73 on the ground. One end of the wire rope 71 is fixed to the lower end of the caisson shaft 1, the middle part passes around the pulley 72, and the other end is wound around the winch 77.

[0048] Because deviations may occur during the sinking process, the caisson module 7 also includes a tension sensor 74, a computer 75, a data acquisition card 76, and a winch 77 to correct for these deviations. The tension sensor 74 is connected to the steel wire rope 71; the tension sensor 74 is electrically connected to the data acquisition card 76; the data acquisition card 76 is electrically connected to the computer 75; the data acquisition card 76 is used to collect the tension data from the tension sensor 74 and transmit it to the computer 75. During the caisson sinking process, the computer 75 acquires and processes the data signals from the tension sensor 74 in real time through the data acquisition card 76. At the initial position, the tension data collected by the tension sensors 74 of each caisson module 7 are almost identical (with a small, permissible error), and this tension data is used as the initial tension data. During the caisson sinking process, if the cutting edge encounters localized hard soil or obstacles, the sinking resistance on that side will increase, resulting in a significant change in the tension value of the corresponding steel wire rope. When the real-time collected tensile data is lower than the predetermined range of the initial tensile data, it can be determined that the side may have encountered greater soil resistance and needs to be corrected. To this end, the computer 75 will send a control command to the sliding motor 41 on the lagging side to increase its cutting power, thereby accelerating the sinking speed of the side until its sinking state returns to equilibrium.

[0049] This embodiment provides a detailed construction process and operating principle for a wall-mounted rotary drilling active sinking caisson device. For specific implementation details, please refer to [link / reference]. Figure 1 and Figure 2 As shown.

[0050] Installation of track module 2: Weld the inner wall steel ring beam 21 and I-beam track 22 to the inner wall of the caisson shaft 1 to form the running track. Hoist the travel motor module 3 to the side of the reserved disassembly track 81, and install the travel motor module 3 into the track through the reserved notch. Align the reserved tenon 83 on the reserved disassembly track 81 with the reserved tenon 82 to install the reserved disassembly track 81.

[0051] Construction of the circulating mud pit 65: A circulating mud pit 65 is excavated in the soil at the center of the caisson as needed, and multi-stage sedimentation is set up to realize the recycling of mud.

[0052] Piping system installation: Install the mud inlet pipe 61 and the slurry outlet pipe 62, as well as pipe fittings 63 and clamps 64. The mud inlet pipe 61 should be a high-pressure resistant flexible hose, and the slurry outlet pipe 62 should be designed with a large diameter to prevent large particles of impurities from entering the pipe and causing blockage.

[0053] The travel motor 31 drives the travel pulley 34 to rotate, enabling the travel motor module 3 to slide smoothly along the ring beam I-beam.

[0054] The cutting motor drives the shaft to rotate via gear transmission. The driving gear 43 and driven gear 44 can be made of high-strength alloy steel, heat-treated to improve wear resistance, ensuring smooth and reliable transmission. The cutting blade 52 can be equipped with cutting teeth, enabling effective breaking of various soil layers. The rotational speed of the cutting blade 52 can be adjusted according to geological conditions.

[0055] The inlet pipe continuously injects high-pressure clean water or mud, which lubricates the cutting surface and reduces sinking resistance. The water injection volume can be adjusted according to the real-time mud concentration.

[0056] High-pressure water or mud is ejected from the nozzle through the channel inside the cutting blade 52, and is fully mixed with the cut soil to form mud.

[0057] The slurry discharge pipe 62 can also be equipped with a concentration sensor. When the mud concentration exceeds the set threshold, the slurry discharge pump will be activated to maintain the mud in the well in a better working state.

[0058] During the caisson sinking process, the computer 75 acquires and processes data signals from the tension sensors 74 in real time via the acquisition card 76. At the initial position, the tension data collected by the tension sensors 74 of each caisson module 7 are almost identical (with a small, permissible error), and this tension data serves as the initial tension data. As the caisson shaft is continuously lowered, the unevenness of the bottom soil causes changes in the tension data. When the real-time acquired tension data falls below the predetermined range of the initial tension data, it can be determined that this side may have encountered significant soil resistance and requires correction. Therefore, the computer 75 sends a control command to the cutting motor 41 on the lagging side to increase its cutting power, thereby accelerating the sinking speed of that side until its sinking state returns to equilibrium. The above acquisition and correction process is performed in real time and under closed-loop control, ensuring that the caisson maintains a stable and uniform sinking posture at all times.

[0059] Device dismantling: Once the caisson has sunk to the designated depth, the caisson sinking operation is complete. At this point, cutting is stopped, the travel motor module 3 is moved to the vicinity of the reserved dismantling track module 8, the reserved dismantling track 81 is lifted, and the travel motor module 3 is hoisted out of the caisson through the reserved notch for continued use in the next project.

[0060] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this invention.
