Description

Technical Field

[0001] The present invention relates to the technical field of novel structures of high-pile docks, and in particular to a high-pile dock with a novel composite foundation adaptive cooperative structure. Background Art

[0002] As the core structure of port projects, the pile foundation system of high-pile wharfs needs to withstand multiple forces such as ship loads, wave impacts and foundation settlement. In recent years, with the trend of large-scale and deep-sea wharfs, load conditions have become increasingly stringent, and the traditional inclined pile system has gradually exposed the problem of insufficient adaptability. For example, in typhoon-prone sea areas, inclined piles may be damaged by accumulated dynamic loads. In soft soil foundations, the loss of soil around the piles will increase the risk of pile foundation instability. Existing reinforcement technologies mostly focus on local reinforcement, lack of systematic solutions, and it is difficult to achieve dynamic load redistribution and long-term self-maintenance.

[0003] In traditional designs, inclined piles are widely used because they can provide lateral resistance to lateral forces. However, when inclined piles are mixed with vertical piles, the horizontal force component can easily cause uneven load distribution in the pile group, which may lead to local settlement or fatigue cracking of the pile body under long-term operation.

[0004] Therefore, we propose a high-pile wharf with a new composite foundation adaptive collaborative structure to solve the above problems. Summary of the Invention

[0008] Preferably, an underwater grouting position is formed between every two of the pile-holding hoop devices, and the pile-holding hoop devices and the high-pile wharf straight piles are cast into one piece by underwater grouting of marine concrete, so as to better transfer the load.

[0010] Preferably, soil is provided between the bottoms of the plurality of cross-connected structural discs, and the plurality of suction cylinders are inserted into the soil.

[0011] Preferably, the upper ends of the prestressed cables are connected to the cross beams of the high-pile wharf to share the horizontal load, and the monitoring device is used to monitor the structural status in real time for dynamic and adaptive adjustment of the prestress.

[0012] Preferably, two sliding holes are opened on the top of the cross-connecting structure disc, and two through holes are opened on the top of the suction cylinder. The inner wall of the suction cylinder is slidingly connected with an extended inner cylinder, and the top of the extended inner cylinder is fixedly connected with two fixed sliding rods, and the outer surfaces of the two fixed sliding rods are slidingly connected with the inner wall of the through hole and the inner wall of the sliding hole respectively.

[0013] Preferably, the inner wall of the suction cylinder is fixedly connected to a space dividing frame, and the space dividing frame is used to divide the interior of the extended inner cylinder into multiple areas, and the bottom of the space dividing frame is fixedly connected to a soil breaking dividing frame, and the soil breaking dividing frame is used to assist the suction cylinder in inserting into the soil.

[0014] Preferably, a threaded fixing ring is fixedly connected between the top ends of the two fixed sliding rods, an adjusting screw is threadedly connected to the inner wall of the threaded fixing ring, the top end of the adjusting screw is fixedly connected to a limiting circular plate, the top of the cross-connecting structure disc is fixedly connected to a support rod, the top end of the support rod is fixedly connected to a mounting block, a forward and reverse motor is provided on the outer surface of the mounting block, and the output shaft of the forward and reverse motor is fixedly connected to the top of the limiting circular plate.

[0015] A construction method for a high-pile wharf with a novel composite foundation adaptive collaborative structure comprises the following steps:

[0016] S1. First, the cross structure is docked. That is, the cross connection structure cantilever is cast and fixed on the four sides of the cross connection structure disc. The cross structure steel cage is hoisted to the top of the suction cylinder. Marine concrete is poured to connect the anchor rods reserved on the top of the suction cylinder. The bottom of the cross connection structure disc is tightly connected to the suction cylinder. This process is prefabricated on the shore.

[0017] S2. Four pairs of upper and lower semicircular cast steel hoops are installed around the four vertical piles of the high-pile wharf. Then, the cantilever of the cross-connecting structure is connected to the hoops of the pile-holding hoops with high-strength bolts. After the foundation load-bearing components are installed, they are positioned and sunk as a whole. The foundation load-bearing components are lowered vertically to the designed position using the existing positioning system and allowed to sink under their own weight. After sinking to a certain depth under their own weight, the existing vacuum pump group is started to pump out the water in the suction cylinder for negative pressure sinking. The sinking rate is controlled, and the inclination of the cylinder top is monitored in real time to ensure the cylinder is vertical. After the sinking is completed, high-pressure cement slurry is injected to seal the cylinder bottom.

[0018] S3. Use underwater grouting to pour marine concrete, integrating the pile-holding hoop assembly with the vertical piles of the high-piled pier. After the grouting solidifies between the foundation load-bearing components and the vertical piles of the high-piled pier, install the prestressed cables. Pass the prestressed cables through the lugs and anchor the upper ends to the bottom of the high-piled pier beams. Monitor stress changes with a monitoring device, and dynamically adjust the cable tension based on data from various sensors.

[0019] S4. By starting the forward and reverse motors, the output shaft drives the adjusting screw to rotate. Since the fixed slide rod slides on the inner walls of the sliding hole and the through hole, the fixed slide rod is limited. Therefore, under the rotation of the adjusting screw, the threaded fixing ring will drive the fixed slide rod to move up and down. When moving downward, the fixed slide rod will push the extended inner tube downward, thereby extending the depth of the suction tube inserted into the soil. By using space dividers to divide the interior of the extended inner tube into multiple chambers, when a single chamber is damaged, it will not affect the overall negative pressure stability. In addition, a soil-breaking divider with a conical overall structure is fixed at the bottom end of the space divider, which is conducive to inserting the suction tube into the soil.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. During use, the elimination of inclined piles improves construction efficiency and shortens construction time. Modular prefabrication reduces the difficulty of on-site operations and reduces overall costs. Composite concrete extends the service life of the structure and reduces maintenance costs. The modular design is easy to replace and dismantle when it reaches its service life. The monitoring system can provide early warning of structural abnormalities and adjust the cable prestressing in time. Data-driven dynamic adjustment of cable tension reduces the structural damage rate under extreme loads. The large proportion of prefabricated suction cylinders and cross structures shortens on-site construction time. Real-time monitoring reduces the frequency of manual inspections and reduces operation and maintenance costs.

[0022] 2. When in use, the bottom of the cross-connected structural disc is tightly connected to the suction cylinder. This process can be prefabricated on the shore. After the foundation force components are installed, they are positioned and sunk as a whole. The foundation force components are lowered vertically to the designed position through the existing positioning system, and are sunk by their own weight. After the self-weight sinking reaches a certain depth, the existing vacuum pump group is started to pump out the water in the suction cylinder for negative pressure sinking. The sinking rate is controlled, and the inclination of the cylinder top is monitored in real time to ensure that the cylinder is vertical. After the sinking is completed, high-pressure cement slurry is injected to seal the bottom of the cylinder. The next step is to carry out the pile hoop. Concrete is poured between the device and the vertical piles of the high-pile pier. Underwater grouting technology is used to pour marine engineering concrete, so that the pile-holding ring device and the vertical piles of the high-pile pier are cast into one, thereby enabling better load transfer. After the grouting between the foundation load-bearing components and the vertical piles of the high-pile pier has solidified, the prestressed cables are installed. The prestressed cables are passed through the lugs and the upper ends are anchored to the bottom of the high-pile pier beams. Then, electric tensioning machines are used for staged tensioning. After tensioning is completed, the stress changes are monitored by monitoring devices, and the tension of the inclined cables is dynamically adjusted based on the data from various sensors.

[0023] 3. During use, by starting the forward and reverse motors, the threaded fixing ring will drive the fixed slide rod to move up and down under the rotation of the adjusting screw. When moving downward, the fixed slide rod will push the extended inner cylinder downward, thereby extending the insertion depth of the suction cylinder into the soil and improving the pull-out resistance and horizontal sliding resistance of the cylinder. By using a space separator, the interior of the extended inner cylinder is divided into multiple chambers. When a single chamber is damaged, it will not affect the overall negative pressure stability, thereby improving the structural redundancy. In addition, a conical soil-breaking separator is fixed at the bottom end of the space separator, which is conducive to inserting the suction cylinder into the soil and has the effect of reducing resistance during insertion.

[0036] The top of the suction cylinder 201 is prefabricated and connected to the bottom of the cross-connecting structure disc 101, and the cross structure composed of the cross-connecting structure disc 101 and the cross-connecting structure cantilever 102 is integrally cast by marine engineering concrete. A three-dimensional steel mesh is configured inside it, and polypropylene fiber is added to enhance crack resistance. An underwater grouting position 107 is formed between each two pile-holding hoop devices 104, and the pile-holding hoop device 104 and the high-pile pier straight pile 4 are cast into one piece by underwater grouting marine engineering concrete to better transfer load. High-pile wharf straight piles 4 are arranged between the pile-holding hoop devices 104, high-pile wharf beams 7 are fixedly connected between the tops of the multiple high-pile wharf straight piles 4, the tops of the prestressed cables 5 are fixedly connected to the bottoms of the high-pile wharf beams 7 at corresponding positions, soil 3 is arranged between the bottoms of the multiple cross-connected structure discs 101, and multiple suction cylinders 201 are inserted into the soil 3. The upper ends of the prestressed cables 5 are connected to the high-pile wharf beams 7 to share horizontal loads, and the monitoring device 6 is used to monitor the structural status in real time for dynamic and adaptive adjustment of the prestress.

[0037] In this embodiment, when in use, firstly, site survey and pretreatment are carried out, and a multi-beam depth sounder and a geological radar are used to conduct seabed geological exploration to confirm the bearing capacity of the soil layer in the installation area of ​​the suction cylinder 201 foundation, and to remove the seabed obstacles to the design elevation. First, the cross structure is docked, that is, the cross connection structure cantilever 102 is cast and fixed on the four sides of the cross connection structure disc 101, and the cross structure steel cage is hoisted to the top of the suction cylinder 201. The marine concrete is poured to connect the anchor rods reserved on the top of the suction cylinder 201, so that the bottom of the cross connection structure disc 101 is tightly connected to the suction cylinder 201. This process can be prefabricated on the shore. Next, the pile-holding hoop device 104 is installed. Four pairs of upper and lower semicircular cast steel hoop are respectively installed around the four high-pile pier straight piles 4. Then the position of the cross-connected structure cantilever 102 is connected to the pile-holding hoop device 104 hoop with high-strength bolts 106. After the installation of the foundation force component 1 is completed, the entire force component 1 is positioned and sunk. The foundation force component 1 is vertically lowered to the designed position through the existing positioning system and allowed to sink by its own weight. After the self-weight sinking reaches a certain depth, the existing vacuum pump group is started to pump out the water in the suction cylinder 201 for negative pressure sinking, the sinking rate is controlled, and the inclination of the cylinder top is monitored in real time to ensure The cylinder is vertical, and after the sinking is completed, high-pressure cement slurry is injected to seal the bottom of the cylinder. The next step is to pour concrete between the pile-holding hoop device 104 and the high-pile pier straight pile 4. The underwater grouting process is used to pour marine engineering concrete, so that the pile-holding hoop device 104 and the high-pile pier straight pile 4 are cast into one, so that the load can be better transferred. After the grouting between the foundation force component 1 and the high-pile pier straight pile 4 is solidified, the prestressed cable 5 is installed. The prestressed cable 5 is passed through the hanging ear 103, and the upper end is anchored to the bottom of the high-pile pier crossbeam 7. Then, an electric tensioning machine is used for graded tensioning. After the tensioning is completed, it is monitored by the monitoring device 6 Stress changes, dynamically adjust the cable tension through various sensor data, eliminate the inclined piles to improve construction efficiency, shorten the construction period, reduce the difficulty of on-site operations, reduce the overall cost, composite material concrete extends the service life of the structure, reduces maintenance costs, and the modular design is easy to replace and dismantle when it reaches its service life. The monitoring system can provide early warning of structural abnormalities and adjust the cable prestress in time. The data drives the dynamic adjustment of the cable tension, reducing the structural damage rate under extreme loads. The suction tube 201 and the cross structure prefabrication account for a large proportion, which shortens the on-site construction period. Real-time monitoring reduces the frequency of manual inspections and reduces operation and maintenance costs.

[0038] Example 2: Figures 1-8As shown, the load transfer assembly 2 includes a suction cylinder 201, two sliding holes 105 are opened on the top of the cross-connected structure disc 101, two through holes 202 are opened on the top of the suction cylinder 201, the inner wall of the suction cylinder 201 is slidably connected with an extended inner cylinder 205, and the top of the extended inner cylinder 205 is fixedly connected with two fixed slide bars 203, and the outer surfaces of the two fixed slide bars 203 are slidably connected with the inner walls of the through holes 202 and the inner walls of the sliding holes 105 respectively, and the inner wall of the suction cylinder 201 is fixedly connected with a space separator 206, and the space separator 206 is used to divide the interior of the extended inner cylinder 205 into multiple areas. The bottom of 06 is fixedly connected with a soil-breaking partition frame 207, and the soil-breaking partition frame 207 is used to assist the suction cylinder 201 to be inserted into the soil body 3. A threaded fixing ring 204 is fixedly connected between the tops of the two fixed slide rods 203. The inner wall of the threaded fixing ring 204 is threadedly connected with an adjusting screw 212. The top of the adjusting screw 212 is fixedly connected with a limiting circular plate 211. The top of the cross-connected structure disc 101 is fixedly connected with a support rod 208. The top of the support rod 208 is fixedly connected with a mounting block 209. The outer surface of the mounting block 209 is provided with a forward and reverse motor 210. The output shaft of the forward and reverse motor 210 is fixedly connected to the top of the limiting circular plate 211.

[0039] When the adjusting screw 212 is rotated, the fixing slide 203 is limited. Therefore, when the adjusting screw 212 is rotated, the threaded fixing ring 204 drives the fixing slide 203 to move up and down. When the fixing slide 203 moves downward, the fixing slide 203 pushes the extension inner tube 205 downward, thereby extending the insertion depth of the suction cylinder 201 into the soil 3 and improving the anti-pulling and anti-horizontal sliding capabilities of the cylinder. By using the space separator 206, the interior of the extension inner tube 205 is divided into multiple chambers. When a single chamber is damaged, it will not affect the overall negative pressure stability, thereby improving structural redundancy. In addition, a conical soil-breaking separator 207 is fixed at the bottom end of the space separator 206, which is conducive to inserting the suction cylinder 201 into the soil 3 and has the effect of reducing resistance during insertion.

[0040] The construction method and working principle of this device: when in use, first conduct site survey and pretreatment, use multi-beam depth sounder and geological radar to conduct seabed geological exploration, confirm the bearing capacity of the soil layer in the installation area of ​​the suction cylinder 201 foundation, remove the seabed obstacles to the design elevation, first carry out cross structure docking, that is, cast and fix the cross connection structure cantilever 102 on the four sides of the cross connection structure disc 101, hoist the cross structure steel cage to the top of the suction cylinder 201, cast marine concrete to connect the anchor rods reserved on the top of the suction cylinder 201, so that the bottom of the cross connection structure disc 101 is tightly connected to the suction cylinder 201. This process can be prefabricated on the shore, and then the pile hoop device 104 is installed, and four pairs of upper and lower semicircular cast steel hoops are respectively enclosed. It is installed around the four high-pile pier straight piles 4, and then the position of the cross-connecting structure cantilever 102 is connected to the pile-holding hoop device 104 hoop with high-strength bolts 106. After the foundation force component 1 is installed, it is positioned and sunk as a whole. The foundation force component 1 is vertically lowered to the designed position through the existing positioning system and allowed to sink by its own weight. After the self-weight sinking reaches a certain depth, the existing vacuum pump group is started to pump out the water in the suction cylinder 201 for negative pressure sinking, and the sinking rate is controlled. The inclination of the cylinder top is monitored in real time to ensure that the cylinder is vertical. After the sinking is completed, high-pressure cement slurry is injected to seal the cylinder bottom. The next step is to pour concrete between the pile-holding hoop device 104 and the high-pile pier straight pile 4. The underwater grouting process is used to pour marine engineering concrete so that the pile-holding hoop device 104 and the high-pile pier straight pile 4 are connected. The vertical piles 4 of the high-pile pier are cast into one piece, so that the load can be better transferred. After the grouting between the foundation force component 1 and the vertical piles 4 of the high-pile pier is solidified, the prestressed cable 5 is installed. The prestressed cable 5 is passed through the hanging ear 103, and the upper end is anchored to the bottom of the high-pile pier beam 7. Then, an electric tensioning machine is used for graded tensioning. After the tensioning is completed, the stress change is monitored by the monitoring device 6, and the tension of the inclined cable is dynamically adjusted according to the data of each sensor. When in use, the forward and reverse motor 210 is started to rotate its output shaft, thereby driving the adjustment screw 212 to rotate. The forward and reverse motor 210 is a waterproof motor that can operate underwater. Since the fixed slide bar 203 slides on the inner wall of the sliding hole 105 and the through hole 202, the fixed The slide bar 203 is limited, so under the rotation of the adjusting screw 212, the threaded fixing ring 204 will drive the fixed slide bar 203 to move up and down. When moving downward, the fixed slide bar 203 will push the extended inner cylinder 205 downward, thereby extending the depth of the suction cylinder 201 inserted into the soil 3, and improving the cylinder's anti-pullout and anti-horizontal sliding capabilities. The top of the extended inner cylinder 205 is hollow, and the soil will pass through the extended inner cylinder 205 into the interior of the suction cylinder 201. By using the space separator 206 to divide the interior of the extended inner cylinder 205 into multiple chambers, when a single chamber is damaged, it will not affect the overall negative pressure stability, thereby improving structural redundancy. In addition, a soil-breaking separator 207 with a conical overall structure is fixed at the bottom end of the space separator 206.It is helpful to insert the suction tube 201 into the soil 3.

[0041] The wiring diagram of the forward and reverse motor 210 and the monitoring device 6 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring layout of the forward and reverse motor 210 and the monitoring device 6 are no longer explained in detail.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

Four pairs of upper and lower semicircular cast steel hoops are respectively installed around four high-pile wharf vertical piles (4), and then the position of the cross connection structure cantilever (102) is connected to the hoop of the pile holding hoop device (104) with high-strength bolts (106). After the foundation force component (1) is installed, it is positioned and sunk as a whole. The foundation force component (1) is vertically lowered to the designed position through the existing positioning system, and is sunk by its own weight. After the self-weight sinking reaches a certain depth, the existing vacuum pump group is started to pump out the water in the suction cylinder (201) for negative pressure sinking, and the sinking rate is controlled. The inclination of the cylinder top is monitored in real time to ensure that the cylinder is vertical. After the sinking is completed, high-pressure cement slurry is injected to seal the cylinder bottom; S3, using underwater grouting technology to pour marine engineering concrete, so that the pile hoop device (104) and the high-pile pier vertical pile (4) are cast into one piece, and after the grouting between the foundation force component (1) and the high-pile pier vertical pile (4) is solidified, the prestressed cable (5) is installed, and the prestressed cable (5) is passed through the lug (103), and the upper end is anchored to the bottom of the high-pile pier crossbeam (7), and the stress change is monitored by the monitoring device (6), and the tension of the inclined cable is dynamically adjusted according to the data of each sensor; S4. Start the forward and reverse motor (210). Under the rotation of the adjusting screw (212), the threaded fixing ring (204) drives the fixed slide bar (203) to move up and down. When moving downward, the fixed slide bar (203) pushes the extension inner cylinder (205) downward, extending the depth of the suction cylinder (201) inserted into the soil (3). Then, the space dividing frame (206) is used to divide the interior of the extension inner cylinder (205) into multiple chambers.
