Description

Technical Field

[0001] The present application relates to the technical field of guide frame vibration sinking construction, specifically to a multi-layer integral sinking guide frame and a vibration sinking construction process. Background Art

[0002] Projects such as urban black and odorous water treatment, water system connectivity improvements, and river restoration often require integrated operations such as dredging, transporting, treating, and placing components in large quantities of sediment. This is particularly true in inland river areas with widespread soft soil and tightly sealed water bodies. These projects often require not only sediment removal but also the establishment of a stable underwater foundation to support subsequent structural construction.

[0003] Existing river dredging operations use long-arm hydraulic excavators, grab cranes, or cutter suction dredgers to excavate and transport the bottom mud. The slurry is typically transported to shore via pipelines for processing using equipment such as plate and frame filter presses, belt thickeners, or centrifugal dewatering.

[0004] However, existing dredging equipment is of a single type and has poor ability to cope with changes in bottom sediments. Areas with mixed rocks and debris often require the collaboration of multiple devices, with many connection links and complex on-site organization. The onshore dosing reaction is not precisely controlled, and large flow fluctuations often lead to a decrease in the efficiency of the agent reaction. The dehydration effect fluctuates significantly. Although geotube bag treatment has certain economic benefits, it is difficult to form a continuous and efficient consolidation system due to its poor adaptability to the site and independent construction process. Therefore, the present invention provides a multi-layer integral sinking guide frame and a vibration sinking construction process to address the shortcomings of the existing technology. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the purpose of this application is to provide a multi-layer integral sinking guide frame and vibration sinking construction technology, which solves the problems of poor assembly accuracy of the existing guide structure, unstable sinking of the structure on the soft foundation, and scattered and inefficient construction process.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a multi-layer integral sinking guide frame, including a guide frame body, an upper movable guide wheel, a middle shoulder pole beam and a lower movable guide wheel. The upper movable guide wheel, the middle shoulder pole beam and the lower movable guide wheel are connected to the trestle load-bearing beam by welding. The upper movable guide wheel and the lower movable guide wheel can be locked and adjusted vertically to protect the anti-corrosion coating on the surface of the steel pipe.

[0007] A vibration sinking construction process for a multi-layer integral sinking guide frame is also provided, comprising the following steps: Use water-based construction equipment equipped with a navigation and positioning system to locate and control the dredging area, and set anchor limits to ensure stable operation of the hull; After positioning is completed, dredging strips are divided according to the working area, excavation is carried out in a fan-shaped horizontal excavation method, and strip overlap belts are set to prevent missed excavation and edge collapse; The dredged slurry is transported to the onshore treatment area through a floating pipe system equipped with buoys and anchoring devices; During the slurry transportation process, cationic flocculants are injected through the dosing device installed in the pipeline to make the slurry-water mixing reaction promote rapid solid-liquid separation; The medicated mud is injected into high-strength filter bags in the onshore anti-seepage yard for dehydration. The yard is equipped with a gravel drainage layer, geotextile and HDPE film to prevent leakage. During the dehydration period of the tube bags, manual intermittent tapping is used to promote drainage. The filtrate is collected, precipitated and tested, and then discharged into the pipe network. After the mud is stabilized, it is covered with soil and greened to form an ecological site.

[0008] Preferably, the above-water construction equipment is an amphibious dredger, and the navigation and positioning system includes a differential global positioning system and HYPACK navigation software for real-time display of the dredging boundary and the auger operation trajectory.

[0009] Preferably, the dredging strips are divided into horizontal strips, the length of a single strip is 30 to 40 meters, the width is the full width of the river channel, and a 1 to 2 meter overlap strip is set between the strips to prevent missing excavation or edge collapse.

[0010] Preferably, the fan-shaped horizontal excavation method is to control the horizontal swing of the cutter with the stern positioning anchor as the center to complete full coverage excavation in a single strip area.

[0011] Preferably, the floating pipe conveying system is composed of a steel pipe and a rubber hose flexibly connected, the floating pipe is supported by a buoy, and anchoring devices are provided along the line.

[0012] Preferably, the dosing device includes a double-layer stirring and dissolving tank and a mechanical diaphragm dosing pump, and the dosing agents include cationic polyacrylamide and PC coagulant aid.

[0013] Preferably, the dosing device dynamically injects drugs into the sludge slurry with a moisture content of more than 80% in the range of 0.5 to 1.5 kg / TDS, and the drugs are fully mixed in the conveying pipeline and then enter the consolidation yard.

[0014] Preferably, the anti-seepage structure of the yard is composed of, from top to bottom: pipe bags, gravel drainage layer, non-woven geotextile, HDPE anti-seepage membrane and compacted foundation, and is provided with an annular drainage ditch and a filtrate collection pool.

[0015] Preferably, after the tube bags are dehydrated, the backfill soil excavated on site is evenly laid on the surface of the tube bags by in-situ covering, with a covering thickness of 30 to 50 cm, and moisture-resistant grass seeds are planted on the covering surface to construct an ecological greening cover layer.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention utilizes a new amphibious dredging equipment that can adapt to various geological environments, replacing traditional long-arm excavators or single-type cutter suction equipment. It simultaneously crushes, cuts, and conveys materials, offering strong adaptability. It eliminates the need for transfer or retooling, resulting in a more seamless construction process. This solves the problems of complex equipment combinations and frequent on-site switching associated with traditional equipment.

[0017] 2. By integrating the flocculation and dosing system directly into the slurry delivery pipeline, this invention allows the chemicals to fully react with the slurry within the pipeline. This results in more uniform mixing and a more continuous process. Unlike the traditional onshore, staged treatment method of adding chemicals and then stirring, this method avoids the problems of incomplete reaction and low dehydration efficiency.

[0018] 3. This invention uses high-toughness polypropylene tubular bags for sludge packaging. These are laid continuously on-site and can be used directly as a construction base after solidification. This eliminates the need to move or stack bags; wherever they are solidified, they become the foundation. This eliminates the need for conventional tubular bags, which require repeated transport and placement, saving space and machinery investment.

[0019] 4. This invention features a multi-layer, integrated sinking guide frame with a high degree of structural integration. It can be hoisted and lowered as a whole, eliminating the need for segmented assembly on site, and the guide holes can be aligned in one go. Compared to conventional split guide frames, this reduces sources of error and avoids repeated leveling and alignment adjustments, resulting in more efficient installation and a more reliable posture.

[0022] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0023] Please see the attached Figure 1 An embodiment of the present invention provides a multi-layer integral sinking guide frame, including a guide frame body 1, an upper movable guide wheel 4, a middle shoulder pole beam 2 and a lower movable guide wheel 3. The upper movable guide wheel 4, the middle shoulder pole beam 2 and the lower movable guide wheel 3 are connected to the trestle load-bearing beam by welding. The upper movable guide wheel 4 and the lower movable guide wheel 3 can be locked and adjusted vertically to protect the anti-corrosion coating on the surface of the steel pipe.

[0024] Specifically, the upper movable guide wheel 4 is used to provide initial guide control for the upper section of the sinking component to ensure the accurate positioning angle of the component; the middle shoulder beam 2 plays the role of maintaining the overall rigidity of the structure and correcting the middle position, thereby enhancing the spatial stability of the guide frame; the lower movable guide wheel 3 is used to realize directional transition control of the end of the component, guiding the component to sink vertically to the design elevation.

[0025] Please see the attached Figure 2 The embodiment of the present invention provides a vibration sinking construction process for a multi-layer integral sinking guide frame, comprising the following steps: S1. Use water-based construction equipment equipped with a navigation and positioning system to locate and control the dredging area, and set anchor limits to ensure stable operation of the vessel; S2. After positioning is completed, desilting strips are divided according to the working area, excavation is carried out in a fan-shaped horizontal excavation method, and strip overlap strips are set to prevent missed excavation and edge collapse; S3, transporting the excavated slurry to an onshore treatment area through a floating pipe system equipped with buoys and anchoring devices; S4. During the slurry transportation process, cationic flocculants are injected through the dosing device installed in the pipeline to make the mud-water mixing reaction promote rapid solid-liquid separation; S5. The slurry after drug addition is injected into high-strength filter bags in the anti-seepage yard on the shore for dehydration. The yard is equipped with a gravel drainage layer, geotextile and HDPE film to prevent leakage; S6. During the dehydration period of the tube bags, manual intermittent tapping is performed to promote drainage. The filtrate is collected, precipitated, and tested before being discharged into the pipe network. After the mud is stabilized, it is covered with soil and greened to form an ecological site.

[0026] Regarding step S1, in this embodiment, before the vibration sinking construction process of the multi-layer integral sinking guide frame begins, in order to ensure the accuracy and continuity of the subsequent dredging operation, it is necessary to position and control the water construction equipment to ensure the dredging line type, operation control and construction efficiency.

[0027] Waterborne construction equipment is an integrated amphibious dredging platform with self-propelled capabilities and dredging capabilities. It can adapt to shallow water and soft ground conditions and can be equipped with various systems, including positioning, auger, and mud transport. Before the equipment is deployed, the construction unit should organize professional personnel to conduct a site survey and develop an equipment deployment plan based on factors such as the water depth, shoreline conditions, equipment size, and traffic organization of the construction area.

[0028] To achieve high-precision path control and stable positioning, a navigation and positioning system, including the Differential Global Positioning System (DGPS), is preferably used for real-time positioning of the equipment. This system typically consists of a shore-based reference signal station and a receiving terminal mounted on the construction vessel. The positioning principle involves the reference station and the vessel-borne terminal synchronously observing multiple navigation satellites, calculating differential corrections based on the observed data, and transmitting these corrections in real time to the vessel-borne terminal via a communication link. This correction is then used to dynamically correct the initial solution for the current construction equipment position.

[0029] During construction, the navigation system, linked to supporting navigation software (such as the preferred HYPACK system), displays information such as the current vessel position, the boundaries of the planned dredging area, the cutter head trajectory, and water depth changes in real time on the construction control terminal. The system can also be linked to water level telemetry devices and cutter depth sensors to display construction cross-sections, longitudinal lines, and operational profiles in real time, providing precise data support for equipment path correction and construction alignment control.

[0030] After completing the preliminary confirmation of the positioning, the construction personnel need to carry out anchoring and control operations on the equipment according to the design drawings and on-site measured conditions to ensure that it maintains a stable posture and a controllable trajectory during the dredging process. The equipment anchoring operation adopts the principle of multi-point limiting. According to the actual water flow direction and wind direction, the upwind or upstream side is preferred for laying the transverse anchor. The order of anchoring needs to be scientifically planned so that the anchor cable forms a certain angle with the center line of the equipment to facilitate the subsequent traction response of the hull during the transverse movement. After the anchoring is completed, the anchor cable should be tightened appropriately to ensure that the anchor claw has grasped the soft soil of the riverbed and has sufficient anti-dragging force.

[0031] After the main anchor is deployed, the vessel is maneuvered to utilize wind and water currents, or with the aid of an auxiliary anchor boat, to move the equipment to the starting position. The other anchor cable is then deployed and tensioned, achieving double-sided anchoring. Under anchor cable tension control, the equipment can perform lateral pulling and rotation operations within a set area, facilitating subsequent fan-shaped excavation.

[0032] The entire positioning and anchoring control process requires coordination with the navigation and positioning system. The system transmits real-time vessel coordinates and path trajectories, which can be used to monitor the anchor cable stress status and equipment displacement trends. If the system detects that the vessel's position has deviated beyond the operational boundary, operators can make real-time adjustments to the anchor cable to ensure the operational path remains aligned with the designed axis.

[0033] Regarding step S2, in this embodiment, after completing the positioning and control of the construction equipment, in order to ensure the systematic nature of the silt removal process and the integrity of the work surface coverage, the entire dredging area needs to be divided into strips in a predetermined manner, and a fan-shaped horizontal excavation method is used to carry out the operations in sequence.

[0034] The desilting area should be divided into strips based on on-site geological survey results, cross-sectional morphology, soil distribution patterns, and hydrodynamic conditions. In practice, construction companies can assess the thickness, distribution, and sedimentary characteristics of the soft soil silt at the riverbed based on the Engineering Geological Survey Report and use this information to rationally designate strip desilting units. The desilting strips are typically arranged along the main stream of the river, with their boundaries taking into account the equipment's operating radius and the pace of construction progress.

[0035] During the implementation of this invention, a fan-shaped horizontal excavation method was employed, using the equipment's stern fixed pile as a fulcrum for horizontal strip excavation. The core of this method is to swing the construction equipment along a fixed axis, forming an arc-shaped desilting strip centered at the fixed point and extending the equipment's operating width. Adjacent strips are then joined together by sequentially moving the equipment.

[0036] Before commencing operations, construction equipment must first set up locating stakes at the starting position of the banner. These stakes are hydraulically controlled and inserted into the riverbed mud layer to form a fixed fulcrum. These stakes are connected to the main body of the equipment via a slideway system installed at the stern of the vessel. They offer a certain range of fore-and-aft sliding capabilities, allowing for dynamic adjustment of the longitudinal position of the vessel during operation. The depth of the stakes should be determined based on the mud hardness and load-bearing capacity required to ensure a stable and reliable fulcrum.

[0037] After positioning is complete, the crew operates the winches on the left and right sides of the equipment's front end to alternately retract and extend the anchor cables, controlling the vessel's left and right swing around the stern positioning pile. The dredging cutter head swings synchronously with the vessel during this process, achieving full coverage of the sector-shaped desilting operation. This method maximizes the width of a single working surface without moving from its current position, thereby reducing the number of repositioning attempts and improving operational continuity.

[0038] To avoid uncovered areas or edge collapse between strips, overlap zones are provided. The overlap design is based on the equipment's lateral coverage radius, the anchor cable's area of action, and the ability to accurately control dredging. Lapping zones are preferably placed in the upstream and downstream directions so that adjacent strips form overlapping dredging paths during actual operation, eliminating blind spots and pile edges.

[0039] The construction process in this step is guided by a navigation system and on-site markings. Construction personnel can observe the operation trajectory and dredging cross-section in real time on display devices, judging whether the fan-shaped operation has achieved the designed coverage effect. If deviations or missed areas are found, localized supplementary excavation can be carried out by adjusting the anchor cable or re-locating the positioning piles to ensure the integrity of the working surface and consistent thickness control.

[0040] In step S3, after completing the strip excavation of the desilted area, the high-water content slurry generated by the dredging equipment must be stably and continuously transported to an onshore processing area for subsequent dosing, dehydration, and consolidation operations. To this end, the construction system incorporates a surface floating pipe transport system, a critical link in the multi-layer, integrally constructed sinking guide frame vibratory sinking construction process. Its layout, structural composition, and operational control directly impact the continuity and safety of the entire construction chain.

[0041] The floating pipe conveying system preferably consists of several rigid steel pipe segments connected to flexible rubber pipe segments. Its structure strikes a balance between transmission strength and layout flexibility. During the piping system design, the steel pipe segments are used to bear pressure and maintain the overall linear structure, while the rubber pipe segments are used to connect to turns or mobile equipment interfaces, alleviating stress concentrations caused by waves, ship movement, or terrain fluctuations. The flexible segments help absorb displacement errors and vibration interference generated during equipment operation, ensuring a continuous and stable conveying process.

[0042] To ensure good buoyancy and stability on the water surface, buoys are installed during construction to provide floating support for the pipeline. Buoys are preferably made of age-resistant plastic or other lightweight, water-resistant materials and are evenly spaced along the entire length of the pipeline. Each buoy can be connected to the pipeline using a lashing device or a floating support. The buoyancy design should meet the requirements for stability under the load of the transported medium and water surface fluctuations.

[0043] During the actual deployment process, to accommodate the on-site river course and the relative positioning of construction equipment and onshore treatment areas, the floating pipe routing should adopt a nearly streamlined curve, avoiding sharp bends or turns to minimize flow resistance and localized wear. Before laying the pipe, surveyors should conduct a full resurvey along the entire route, determining the optimal routing path based on on-site water depth, current velocity, and navigation conditions to ensure the pipeline does not intersect with other structures or the construction area.

[0044] Considering the uncertainty of the water surface environment and the response characteristics of the floating pipe system to environmental loads, an anchoring system is installed along the pipeline during construction. Preferably, each continuous section of pipeline can be equipped with multiple anchor cables, and bidirectional anchoring can be set up in specific sections according to environmental conditions to form a stable anti-floating structure. Anchoring devices include anchor blocks, anchor cables, and limit piles, which can be flexibly selected based on the water depth and soil conditions of the construction area. The anchor cable should be equipped with a tension adjustment structure to facilitate the timely adjustment of the floating pipe position under water level fluctuations or wind and wave effects to prevent drift or entanglement.

[0045] To ensure secure and reliable connections in the pipeline system, steel pipes and rubber hoses are secured using the preferred clamping method. The clamp structure should possess sufficient clamping force and corrosion resistance to ensure leak-proof and non-loosening seals in humid, high-pressure, and dynamic load environments. Expansion margins are preset between each connection section to accommodate pipeline deformation caused by temperature fluctuations and operational loads during construction.

[0046] The slurry generated by the dredging equipment's cutter is pumped directly into a floating pipe system, where it is transported along the water surface to an onshore treatment yard. At the end of the floating pipe, the slurry is connected to the dosing network or filling bag within the yard via a diverter or adapter hose, creating a continuous flow path. The entire floating pipe system must be visually and securely marked to prevent accidental contact and navigational hazards during operation. Inspection points should also be established to facilitate subsequent maintenance and troubleshooting.

[0047] Regarding step S4, in this embodiment, in the process of transporting the mud generated by dredging to the onshore treatment area through the floating pipe system, in order to achieve rapid aggregation and sedimentation of suspended particles in the sludge and enable it to have the initial structural strength required for subsequent dehydration and consolidation, a dosing and mixing reaction operation is simultaneously carried out during the transportation process.

[0048] The dosing operation is based on the dynamic flow state of the mud and is carried out in an online dosing manner. The chemical and the high-water content mud are fully mixed and reacted in the flow path inside the pipeline to complete the preliminary treatment of solid-liquid pre-separation and improve the dewaterability of the mud after entering the filter bag.

[0049] Preferably, the dosing system is located in the midstream and downstream sections of the delivery float, connected to the float system via flanges or quick connectors. It includes functional modules such as a dissolving device, a dosing pump, a liquid mixing system, and a dosing inlet. The dissolving device is equipped with a continuously operating mechanical stirring device to ensure the full integration of the agent and solvent during the dosing process, preventing precipitation or agglomeration.

[0050] The agents used include a primary flocculant and a coagulant aid. The primary flocculant is preferably cationic polyacrylamide (PAM), whose molecular chain structure has strong electrical capture capabilities, allowing it to quickly combine with negatively charged suspended particles in the slurry to form flocs. The coagulant aid is preferably a composite inorganic or organic settling agent, which further enhances the flocculation effect and forms large-particle sediments.

[0051] Clean river water is used as the solvent for dissolving the agent. The main flocculant solution has a mass concentration range of 0.5% to 1.0%, and the coagulant aid concentration ranges from 5% to 15%. After dissolution, the agent enters the liquid storage tank, which is connected to the dosing pump. The dosing pump is preferably a diaphragm metering pump. By precisely controlling the pumping frequency and single delivery volume, stable and continuous dosing of the flocculant is achieved.

[0052] The dosage ratio of the agent to the slurry is adjusted based on the slurry's moisture content, particle composition, and treatment objectives. Based on testing and experience, the dosage range for cationic polyacrylamide is controlled between 0.5kg / TDS and 1.5kg / TDS, where TDS represents the total solids content in the slurry. The dosage ratio of the coagulant aid can be flexibly adjusted based on the slurry's flow rate and structural stability, with the dosage ratio controlled between 1:10 and 1:15 (volume ratio).

[0053] Dosing is accomplished through the mixing section of the pipeline. This section, located downstream of the reagent injection port, features a flow-disturbing structure. Its design enhances fluid rotation and turbulence, ensuring rapid and effective flocculant-slurry contact. The flocculation reaction time depends on the length of the pipe section, flow rate, and flocculant reaction speed. System adjustments can be made to optimize the online reaction.

[0054] The reacted mud will carry the initially formed flocs and continue to be transported to the onshore consolidation yard through the floating pipe system. Before arriving at the yard, the mud should maintain a certain fluidity to ensure that it can further complete the sedimentation, water filtration and consolidation processes in the filter bags.

[0055] In this embodiment, by linking the dosing system with the conveying system and employing an online mixing and reaction method, manual intervention in the construction process can be reduced while also improving the continuity of mud treatment. The dosing equipment's operation is controlled by a control system that implements parameter presets and adaptive flow rate control. This automatically adjusts to the actual on-site mud flow rate, ensuring stable and controllable dosing accuracy and mud-water reaction.

[0056] In step S5, after the mud's mixing reaction is complete, the slurry, which has formed a preliminary flocculent structure, is transported to an onshore dewatering site. A high-strength bag-and-tube system is then deployed there to complete the dewatering and consolidation of the slurry. This step constitutes a key slurry terminal disposal process unit in the multi-layer, integrated sinking guide frame vibration sinking construction system described herein, directly impacting the achievement of sustainable development and environmental safety control goals within the construction area.

[0057] The dewatering site is preferably located in a temporary work area with heaping capacity within the construction area. Its location should take into account convenient transportation, unimpeded drainage, and a flat surface. The site foundation is reinforced by bulldozing, compaction, or the laying of geotechnical materials to increase its ability to withstand the pressure of mud bag loads. To prevent mud from seeping out and contaminating the surrounding soil, the site surface is preferably covered with a high-strength impermeable membrane. High-density polyethylene (HDPE) or other chemically resistant membrane materials can be used for the impermeable membrane, and the seams are laid continuously using hot melt or adhesive bonding to ensure a sealed and complete bottom surface.

[0058] After the dewatering site foundation is completed, high-strength tubular bags, specifically designed for sludge dewatering, are laid atop. These tubular bags are enclosed filtration structures made from woven synthetic fiber, offering tensile strength, water permeability, and mud-proof properties. When laying out the tubular bags, consideration must be given to the positioning of the slurry inlet, the spacing between bags, the direction of the drainage channel, and the provision of access channels. The bags should be laid in a matrix arrangement, tailored to the site's topography and drainage flow. A lightweight support net or gravel layer can be placed between the bags and the ground to ensure uniform contact with the foundation.

[0059] The slurry is injected directly into the deployed pipe bags through a pipeline system. To ensure uniform and stable grouting, the slurry inlet is located in the middle or at both ends of the upper end of the bag and connected to the pipeline via a quick connector. During the grouting process, the grouting rate and pressure are adjusted using a control valve, flow meter, and pressure feedback device to prevent local expansion and instability of the bag or rupture of the pipe bag.

[0060] During the slurry injection process, flocs formed by the reagent reaction gradually settle within the bag, and free water is discharged through the bag fibers under the influence of gravity and the internal and external pressure differential. To guide the escaped water to orderly collect and discharge from the site, a system of drainage ditches and diversion channels is installed within the site, with the bottom of the channel connected to a sedimentation tank or temporary drainage pond. To prevent the leakage of muddy water, the drainage system should also be equipped with an impermeable lining and can be equipped with mesh filter cloth to prevent the flocs from flowing out with the water.

[0061] To improve the consolidation efficiency of the slurry within the bag, a constrained ballast structure is preferably added to the top of the tube bag in this embodiment. Ballast can be applied using woven sand bags, prefabricated water bags, or lightweight steel plates. Its primary function is to increase the slurry's settling pressure, control the bag's expansion shape, and accelerate the rate of free water discharge. Ballasting should be performed after the initial grouting phase has stabilized to avoid disturbing the established floc structure.

[0062] The bag dehydration process is gradual and is affected by multiple factors, including ambient temperature, the degree of chemical reaction, and initial moisture content. Throughout the dehydration cycle, construction personnel should regularly monitor the bag's settlement and dehydration results. By adjusting the slurry feed cycle, intermittent periods, or re-adding chemicals and slurry, they can maintain a controlled state of consolidation reaction within the bag.

[0063] After the tube bags have completed initial dehydration and reached a certain consolidation strength, the resulting bagged consolidation body can continue to be used as an in-situ loading structure or, depending on the construction schedule, be transported, compacted, or covered with soil for greening. If used for in-situ backfill or ecological restoration, soil can be backfilled in the gaps between the bags to form a stable base, upon which new bags can be stacked or anti-scouring gullies can be constructed, thus achieving a functional transformation of the site.

[0064] In step S6, in this embodiment, after completing the strip-by-strip dredging, chemical dosing, and filter bag dehydration and consolidation operations, a sludge consolidation base layer with a certain bearing capacity and flatness is formed on-site. Based on this consolidation base layer, the overall alignment and sinking of the guide frame assembly is initiated to form a positioning and restraining structure for the subsequent pile vibration sinking construction.

[0065] The guide frame described in this invention is a multi-layered, monolithic structure composed of several horizontal beams, vertical supports, and connecting nodes, forming a spatially rigid framework. This structure features multiple vertical openings or slots that constrain the vertical direction and spatial position of the vibratory pile, ensuring the accuracy of the pile's path into the soil.

[0066] Before placing the guide frame, the bag consolidation site must be leveled and rechecked to confirm that its surface elevation, bearing capacity, and bag layout meet the requirements for guide frame placement. For areas with large elevation differences or insufficient bearing capacity, appropriate backfilling with crushed stone or laying loaded sandbags can be used to create an acceptable bearing base.

[0067] The guide frame is prefabricated onshore and assembled in modular form. It is preferably transported to the designated installation area by integral hoisting. During transportation, position-limiting brackets and buffer components are used to constrain the guide frame's posture to prevent displacement, distortion, or structural deformation caused by uneven force.

[0068] The entire hoisting operation is preferably performed using a floating crane platform or shore-based lifting equipment. The guide frame is connected to the lifting rigging via lifting points. These lifting points should be located at multiple, evenly spaced locations near the guide frame's center of gravity to ensure stable positioning during lifting and lowering. During the lifting process, the operator coordinates and synchronizes the lowering speed of each lifting point through signals to achieve stable overall alignment.

[0069] After the guide frame is hoisted above the site, it must be precisely positioned. This embodiment utilizes a composite positioning system, combining GPS coarse positioning with manual ranging to assist positioning. Several positioning stakes or reference points are deployed on-site and aligned with control points on the guide frame structure. Real-time measurement and fine-tuning are performed using a total station or laser rangefinder to ensure that the guide frame's position matches the designed positioning axis.

[0070] After positioning verification is complete, slowly lower the guide frame to the intended placement position. To ensure reliable contact between the guide frame and the filter bag base, this embodiment preferably incorporates multiple distributed cushioning legs. These legs utilize adjustable height pads or support plates to accommodate local elevation differences, ensuring uniform force distribution at each support point and preventing deformation or damage to the filter bag caused by concentrated loads.

[0071] Once the guide frame is in place, it is temporarily secured using limited anchoring devices installed at the base or perimeter of the structure. These anchoring devices consist of adjustable steel anchor plates or castable enclosed chambers. These anchors create initial frictional resistance between the load transfer structure and the foundation, preventing lateral movement of the guide frame due to water flow or construction vibrations.

[0072] To further stabilize the guide frame's vertical posture and suppress structural drift after sinking, the structure can be pre-installed with sand-filled chambers or ballast modules. After sinking, mortar or weighted materials are poured to form a stable mass, enhancing the guide frame's resistance to static and dynamic loads.

[0073] Once the guide frame is initially positioned and securely placed, its key components and guide holes can be rechecked. This inspection includes the verticality of the opening axes on each level, the consistency of relative elevations, and the matching of hole diameters. If necessary, fine-tuning can be performed using shims, correction bolts, or local adjustment components to ensure that the guide function meets the accuracy requirements of subsequent vibration sinking operations.

[0074] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
