Description

Technical Field

[0001] The invention belongs to the technical field of engineering machinery, and in particular relates to an above-water wheel-rail type remote-controlled piling platform and a method. Background Art

[0002] In bridge construction projects, vibrating pile drivers are important equipment for pile foundation construction of large temporary facilities. The principle is to use the exciting force of the pile hammer to liquefy the outer wall soil of the steel pile, reduce the friction resistance of the inner and outer surfaces of the steel pile to the soil, and then insert the pile body into the soil by the exciting force plus the deadweight of the pile body and the deadweight of the hammer body, so that the pile body is driven into the predetermined depth to serve as the foundation of the large temporary structure of the bridge construction. When the existing pile driver is working on the water, it needs to use the water body to float, and the steel pile materials also need to be transported by ship, so that its operation mode is affected by the depth of the water. Especially in shallow water environment, the water pile driver itself and large ships are difficult to move, resulting in slow efficiency of pile driving and high construction costs; and in the beach environment near the water, ordinary pile drivers and steel pile transportation will also encounter such difficulties of movement blockage and inconvenience in operation; this type of operation also has the problem of pile driving equipment being unable to move, steel piles being unable to be transported, and inconvenience in operation in shallow water, beach and other environments. Therefore, a new technical solution is needed to solve the above problems. Summary of the invention

[0003] In view of the deficiencies in the above-mentioned prior art, the present invention provides an above-water wheel-rail remote-controlled piling platform and method, which are used to expand the application scope of above-water piling, improve piling efficiency, reduce construction costs, and create greater economic and social benefits for bridge construction.

[0004] The present invention is implemented through the following technical scheme: an above-water wheel-rail remote control piling platform, comprising a plurality of steel piles, a plurality of Bailey beams, a plurality of electric control trolleys, a platform, a crawler crane, and a vibrating pile hammer. The lower sections of the plurality of steel piles are inserted into the foundation, wherein at least two of the steel piles are used to support a Bailey beam, the bottom wheel rail of the electric control trolley is fixed on the Bailey beam, and the wheel rail body is parallel to the extension direction of the Bailey beam body; a plurality of electric control trolleys are jointly supported to form a platform, on which the crawler crane and the electric control cabinet are placed, the crawler wheel of the crawler crane moves in a direction perpendicular to the extension direction of the Bailey beam body, and at the same time, the body of the crawler crane is rotatably assembled on its chassis, and the boom of the crawler crane is hingedly assembled on its body; the end of the boom suspends a vibrating pile hammer through a steel wire rope, and a clamp is installed at the bottom of the vibrating pile hammer.

[0005] Furthermore, the Bailey beam is supported and fixed on the distribution beam on the top of the steel pile, and the wheel rail at the bottom of the wheel of the electric control trolley is fixedly supported by multiple transversely arranged cushion beams, and the multiple transversely arranged cushion beams are all supported by the Bailey beam.

[0006] Furthermore, the Bailey beam is composed of multiple Bailey plates and multiple transverse connecting rods in the transverse direction, which are connected into a force-bearing whole by bolts. The transverse spacing of the Bailey plates can be a module of 450mm, and the Bailey beam is extended longitudinally by Bailey pins to form a continuous Bailey beam. The Bailey beam is installed and fixed on the top distribution of the steel pile, and a transverse cushion beam and two wheel rails are installed and fixed on the Bailey beam, and the remote control trolley walks on the two wheel rails.

[0007] Furthermore, a plurality of the steel piles and a plurality of transversely connected steel sections plus a top distribution beam are welded to form a truss tube structure on the foundation.

[0008] Furthermore, the connection parts between the upper and lower ends of the Bailey frame and the cushion beam and the distribution beam respectively can be fixed by connecting a fixed clamp or U-shaped bolts, the U-shaped structural groove of the fixed clamp is buckled on the Bailey frame, and the fitting parts of the fixed clamp, the cushion beam and the distribution beam are welded and fixed.

[0009] Furthermore, a transport vehicle is provided at the rear of the platform, on which a plurality of transversely arranged steel piles are mounted, and the bottom of the transport vehicle is supported by a plurality of the electric-controlled trolleys.

[0010] Furthermore, the crawler crane has a lifting capacity of 50 to 80 t, and the boom of the crawler crane can lead out a plurality of steel wire ropes to lift the Bailey beam, and can cantilever the vibratory pile hammer to drive piles.

[0011] Furthermore, the electric-controlled trolley is driven by remote control, and the driving motor of the electric-controlled trolley is equipped with a brake and a worm gear reducer. Each electric-controlled trolley is provided with a track clamp, and the track clamp is a hydraulic track clamp, which clamps the wheel rail in a normally closed state, and its anti-slip force is ≥150KN. The opening trigger signal of the track clamp is the driving signal of the motor. At the same time, each electric-controlled trolley is also provided with a hydraulic lifting device, and the platform is kept in a horizontal state through the support of the hydraulic lifting devices of multiple electric-controlled trolleys. The control modules of the driving motor, brake and multiple hydraulic lifting devices of the remote-controlled trolley are all concentrated in one remote control device.

[0012] The present invention also provides an on-water wheel-rail remote control piling method, comprising the following steps:

[0013] S1: At least three rows of steel piles are driven into the beach or shallow waters by the vibrating pile hammer of the crawler crane on the shore (at least two in each row), and then two rows of Bailey beams (two in each row), multiple electric-controlled trolleys, platforms and crawler cranes are placed on the steel pile array, wherein the two Bailey beams in each row are fixedly connected by Bailey pins. The new steel piles on the shore are first clamped by the clamp on the vibrating pile hammer, and the platform and crawler crane are transported to the end of the Bailey beam away from the shore by the movement of the electric-controlled trolley on the wheel rail, and then the boom of the crawler crane is rotated and the steel wire is released synchronously. The rope is used to move the new steel pile held by the vibrating pile hammer from top to bottom and align it with the construction area. The vibrating pile hammer is turned on to insert the steel pile into the soil through the exciting force. According to the vibration liquefaction principle of the soil, the soil particles and pore water are mixed to form a suspension state and the friction resistance of the inner and outer surfaces of the steel pile to the soil is reduced. Then, the steel pile body is inserted into the soil by the exciting force plus the deadweight of the steel pile and the deadweight of the vibrating pile hammer. When the steel pile is driven to the designed elevation or reaches the required penetration (or until the pile does not sink, drive for about 6 minutes), the vibrating pile hammer clamp is released to complete the piling operation of the new steel pile.

[0014] S2: Start the electric control trolley to adjust the position of the crawler crane so that it is close to the shore, and then start the crawler crane to rotate its boom to the side closer to the shore, pull out multiple steel wire ropes from the boom end and lift and connect the new Bailey beam stored on the shore, start the electric control trolley again and restart the boom to rotate it to the side away from the shore, move the lifted new Bailey beam to the top of the steel pile away from the shore, and then extend the steel wire rope synchronously to place the new Bailey beam flat on the steel pile and keep lifting it, ensuring that the pin holes of the new Bailey beam and the adjacent Bailey beam are concentric, and then insert the Bailey pin to fix the two, completing the extension and beam erection operation of the new Bailey beam.

[0015] Furthermore, the present invention further comprises the following steps:

[0016] S3: Continue to repeat the piling operation of step S1 and the beam erection operation of step S2 alternately, and ensure that the erected Bailey beams are not dismantled and used as transportation channels for steel piles and materials and walking channels for electric-controlled trolleys, so as to extend the steel pile array and Bailey beam array to the deep water area. At this time, ensure that a transport vehicle loaded with steel pile materials is connected to the rear of the platform. The bottom of the transport vehicle is driven by multiple electric-controlled trolleys so that it can move synchronously with the platform. After each crawler crane is used to lift a new Bailey beam on the shore, the electric-controlled trolley is started to make the platform and the transport vehicle move synchronously to the end of the Bailey beam far away from the shore, and the lifted new Bailey frame is placed on the The beam is installed on the steel piles, and then the electric-controlled trolley is directly moved to the newly erected Bailey beam. The crawler crane boom is turned and the steel wire rope is led out to lift the new steel piles in the transport vehicle. The boom is turned again to insert the new steel piles into the far soil and the piling work is completed with a vibrating pile hammer, thereby realizing the continuous implementation of beam erection and piling operations in a single round trip. At the same time, through the lateral movement of the crawler wheels on the platform and the rotation of the crawler crane body, the crawler crane boom can be extended in the lateral direction of each row of steel piles (this direction is perpendicular to the Bailey beam body) to implement pile laying, ensuring continuous piling operations in a large longitudinal and lateral operating range;

[0017] S4: As the steel pile array is continuously extended in the beach, shallow water, deep water and other areas, vibratory pile hammers of different sizes are selected according to the geological conditions of different areas to ensure that the exciting force of the vibratory pile hammer can drive the steel piles into the design required elevation. The exciting force of the vibratory pile hammer can be selected in the range of 380 to 1390 KN, and the magnitude of the exciting force is directly proportional to the soil hardness.

[0018] Furthermore, the present invention further comprises the following steps:

[0019] S3: Start the electric control trolley to adjust the position of the crawler crane, and then start the crawler crane to rotate its boom to the side closer to the shore. At this time, remove the Bailey pins on the adjacent Bailey frames, pull out multiple steel wire ropes from the end of the boom and connect the Bailey frames close to the shore by lifting. Restart the boom to rotate it to the side away from the shore, move the lifted Bailey frames to the top of the steel piles away from the shore, and at this time, extend the steel wire ropes to place the Bailey frames flat on the steel piles and keep lifting them, ensuring that the pin holes of the alternating Bailey beams are concentric with those of the adjacent Bailey beams, and then insert the Bailey pins to fix the two. The alternating beam erection and arrangement work is completed, and the Bailey beam alternating operation of step S2 is repeated by analogy. The positions of the two Bailey beams are alternately used to implement continuous piling operations on the infinite path ahead, and a barge loaded with new steel piles and accessories is used to follow in real time as a material supply for the continuous piling operation. At the same time, through the lateral movement of the crawler wheels on the platform and the rotation of the crawler crane body, the crawler crane boom can be extended in the lateral direction of each row of steel piles (this direction is perpendicular to the Bailey beam body) to implement pile laying, ensuring continuous piling operations in a larger operating range in the longitudinal and lateral directions;

[0020] S4: As the steel pile array is continuously extended in the beach, shallow water, deep water and other areas, vibratory pile hammers of different sizes are selected according to the geological conditions of different areas to ensure that the exciting force of the vibratory pile hammer can drive the steel piles into the design required elevation. The exciting force of the vibratory pile hammer can be selected in the range of 380 to 1390 KN, and the magnitude of the exciting force is directly proportional to the soil hardness.

[0021] Furthermore, when the piling operation is carried out according to step S1 or the beam erection operation is carried out according to step S2, the hydraulic lifting device on each electric-controlled trolley is centrally controlled by a remote control device according to the inclination angle of the Bailey beam, so that the support of the platform by multiple hydraulic lifting devices is kept in a horizontal state, and then inclined pads are inserted between the platform and the trolley to support it firmly, thereby ensuring the rigid support state of the platform and making the hydraulic lifting device no longer subjected to stress, so as to carry out the piling or beam erection operation.

[0022] The beneficial effects of the present invention are:

[0023] 1. The present invention forms flexible support, adjustment and conversion functions for batch piling operations through Bailey beams, electric-controlled trolleys, platforms and crawler cranes on multiple steel piles. After the Bailey beams are supported and installed by the initial several steel piles, the boom of the crawler crane is used to lift and transfer the subsequent Bailey beams to the front steel pile position for repeated piling operations. At the same time, the vertical and horizontal movements of the electric-controlled trolley and crawler wheels on the Bailey beam plane can enable the boom to achieve continuous piling functions in all directions, with a large operating range and unlimited paths. The overall process only requires the establishment of several initial steel piles on the shore, and the subsequent work can be completed by the alternating movement of the Bailey beams, so that the operating equipment is supported by the steel piles themselves throughout the process without being affected by the beach and shallow water environment, and continuous operation, transportation and supply are convenient and fast, which greatly improves the adaptability of piling operations to different beaches and different waters, achieves high-efficiency and low-cost construction effects, and creates greater economic and social benefits for bridge construction.

[0024] 2. The present invention has two water piling construction operation modes. One piling mode is to keep the Bailey beam at the rear intact (as a support for subsequent beam erection) and use it as a walking passage for transporting steel piles, materials and trolleys to adapt to piling and beam erection operations in different areas such as shores, beaches, and shallow waters. The other piling mode is that in deep water areas or when the Bailey beam cannot be installed synchronously, steel piles and materials can be transported to the front of the wheel-rail remote-controlled piling platform by barge. The crawler crane on the platform directly lifts materials from the ship. The length of the Bailey beam required to support the crawler crane only needs to be the length of the interval between the two rows of steel piles. The rear row of Bailey beams are hoisted to the front by cyclic hoisting for alternating installation, thereby infinitely advancing the operation path. These two water piling modes have high applicability and can be applied to shores, beaches, shallow waters and deep waters. Pile driving has a wide range of piling operations, high automation and piling precision, and low construction cost. At the same time, the remote-controlled piling platform integrated with the trolley, platform and crane is convenient for rapid installation, dismantling and transportation, and it is also highly applicable to different transportation environments. Since the remote-controlled piling platform is a prefabricated construction equipment, its Bailey beam and crawler crane can be rented in areas where water piling is required, and the electric-controlled trolley and platform can meet the conditions of road car transportation, which is convenient for transportation, warehousing, storage and maintenance. Compared with traditional ship-type equipment for water piling, this equipment is not affected by transportation conditions, and its scope of use is widely distributed throughout the country, and it is convenient and fast to transfer to various regions with low cost, and has good market prospects.

[0025] 3. The present invention utilizes the hydraulic lifting devices on multiple trolleys to jointly level the platform. Through the integrated setting of the electronic control systems of multiple electric-controlled trolleys on the wireless remote control device, the synchronous lifting and independent lifting of the hydraulic lifting devices on each trolley can be remotely controlled in a centralized manner, so that the platform is always in a horizontal state in a highly efficient control manner. When the platform is leveled, inclined pads are used to firmly support the platform and the electric-controlled trolley, so that the working platform is rigidly supported and the hydraulic lifting device is no longer subjected to stress. This process technology can better improve the working stability of crawler cranes in beam erection and piling operations, break through the technical bottleneck of traditional water piling modes, and effectively improve the efficiency, accuracy and anti-interference of piling operations.

[0026] 4. The present invention realizes a secondary braking effect through the one-way braking and reverse self-locking functions of the driving motor brake and the worm gear reducer on the electric control trolley. At the same time, the normally closed state of the hydraulic clamp can ensure that the electric control trolley is firmly connected to the wheel-rail and Bailey beam in a non-traveling state. The clamp will only open automatically when the motor is powered on and running, and the wheel-rail will be firmly clamped when the motor is powered off and stopped. Multiple protection measures are used to effectively ensure the smooth implementation of piling and beam erection operations. Compared with traditional water piling devices, the present invention has higher safety and reliability.

[0027] 5. The present invention adopts a transport vehicle separately arranged on the Bailey beam to transport steel piles and materials. When the electric-controlled trolley drives the transport vehicle to load steel piles and materials on the shore and transport them to the rear of the crawler crane, the piling and beam erecting operations of the front crawler motor can be carried out simultaneously. Compared with the traditional method of transporting steel piles and materials by water, this technology has the characteristics of fast transportation speed, high efficiency and low cost.

[0028] 6. The present invention also forms a truss tube system through the bottom steel piles, distribution beams, transverse connecting rods and the foundation, which improves the overall bending and shear resistance in all directions (especially horizontal and vertical directions), and effectively ensures that the operational impact loads generated by beam erection, piling, loading and transportation are directly borne by the foundation. In addition, due to the excellent lateral force resistance formed by the truss tube structure, the subsequent use of Bailey beams and steel piles to build bridges can effectively improve the interference resistance to wind and earthquake forces, thereby improving the overall process quality of bridge construction.

The Bailey beam 2 is composed of multiple Bailey plates 2a and multiple transverse connecting rods 2b in the transverse direction, which are connected by bolts to form a force-bearing whole. The transverse spacing of the Bailey plates 2a can be a module of 450mm. The Bailey beam 2 is extended longitudinally by Bailey pins to form a continuous Bailey beam 2. The Bailey beam 2 is installed and fixed on the top distribution of the steel pile 1. The transverse cushion beam and two wheel rails are installed and fixed on the Bailey beam 2, and the remote control trolley walks on the two wheel rails. Multiple steel piles 1 and multiple transverse connecting steels 1b plus the top distribution beam 1a are welded to form a truss tube structure on the foundation.

Each electric control trolley 3 is provided with a rail clamp, which is a hydraulic rail clamp. The clamping state of the wheel rail 3a is normally closed, and its anti-slip force is ≥150KN. The opening trigger signal of the rail clamp is the driving signal of the motor. At the same time, each electric control trolley 3 is also provided with a hydraulic lifting device 3d. The platform 4 is kept in a horizontal state by the support of the hydraulic lifting devices 3d of multiple electric control trolleys 3. The control modules of the driving motor 3c, brake and multiple hydraulic lifting devices 3d of the remote control trolley are all concentrated in one remote control device. The crawler crane 5 and the electric control cabinet are placed on the platform 4. The lifting capacity of the crawler crane 5 is 80t. The moving direction of its crawler wheel 5a is perpendicular to the extending direction of the Bailey beam 2. At the same time, the body of the crawler crane 5 is rotatably assembled on its chassis, and the boom 5b of the crawler crane 5 is hingedly assembled on its body; the end of the boom 5b suspends a vibrating pile hammer 6 through a wire rope 5c, and a clamp is installed at the bottom of the vibrating pile hammer 6.

[0042] The working steps of this embodiment are as follows:

[0043] S1: Figure 5As shown, at least three rows of steel piles 1 are driven into the beach or shallow water (at least two in each row) by the vibrating pile hammer 6 of the crawler crane 5 on the shore, and then two rows of Bailey beams 2 (two in each row), a plurality of electric-controlled trolleys 3, a platform 4 and the crawler crane 5 are arranged on the steel pile 1 array, wherein the two Bailey beams 2 in each row are fixedly connected by Bailey pins, and the new steel piles 1 on the shore are first clamped by the clamp on the vibrating pile hammer 6, and the platform 4 and the crawler crane 5 are moved by the electric-controlled trolley 3 on the wheel rail 3a. The crawler crane 5 is transported to the end of the Bailey beam 2 away from the shore, and then the boom 5b of the crawler crane 5 is rotated and the wire rope 5c is released synchronously, so that the new steel pile 1 clamped by the vibrating pile hammer 6 moves from top to bottom and is aligned with the construction area, and the vibrating pile hammer 6 is turned on to insert the steel pile 1 into the soil through the exciting force. According to the vibration liquefaction principle of the soil, the soil particles and the pore water are mixed to form a suspension state and reduce the friction resistance of the inner and outer surfaces of the steel pile 1 to the soil. Then, the steel pile 1 is inserted into the soil by the exciting force plus the deadweight of the steel pile 1 and the deadweight of the vibrating pile hammer 6. When the steel pile 1 is driven to the designed elevation or reaches the required penetration (or until the pile does not sink, and then drive for about 6 minutes), the vibrating pile hammer 6 clamp is released to complete the piling operation of the new steel pile 1;

[0044] S2: Figure 6 As shown, the electric control trolley 3 is started to adjust the position of the crawler crane 5 so that it is close to the shore, and then the crawler crane 5 is started to rotate its boom 5b to the side biased to the shore, and multiple steel wire ropes 5c are pulled out from the end of the boom 5b to carry out the lifting and connection of the new Bailey beam 2 stored on the shore, and the electric control trolley 3 is started again and the boom 5b is restarted to rotate it to the side away from the shore, and the lifted new Bailey beam 2 is moved to the top of the steel pile 1 away from the shore, and at this time, the steel wire rope 5c is synchronously extended to place the new Bailey beam 2 flat on the steel pile 1 and keep lifting, ensuring that the pin hole of the new Bailey beam 2 is concentric with that of the adjacent Bailey beam 2, and then the Bailey pin is inserted to fix the two, and the extension beam erection operation of the new Bailey beam 2 is completed;

[0045] S3: Figure 7-8As shown, the piling operation of step S1 and the beam erection operation of step S2 are continued to be repeated alternately, and at the same time, it is ensured that the Bailey beam 2 that has been erected is not dismantled and serves as a transportation channel for steel piles 1 and materials and a walking channel for the electric control trolley 3, so that the array of steel piles 1 and the array of Bailey beams 2 are extended and arranged in the deep water area, and the upper and lower ends of the Bailey frame are respectively fixed to the connection parts with the cushion beam 3b and the distribution beam 1a through the fixing card plate 2c, and the U-shaped structural groove of the fixing card plate 2c is buckled on the Bailey frame, and the fitting parts of the fixing card plate 2c, the cushion beam 3b and the distribution beam 1a are welded and fixed (this welding structure is used as part of the subsequent bridge facilities), At this time, ensure that a transport vehicle 7 loaded with steel piles 1 is connected to the rear of the platform 4. The bottom of the transport vehicle 7 is driven by multiple electric-controlled trolleys 3 so that it can move synchronously with the platform 4. After each crawler crane 5 is used to lift a new Bailey beam 2 on the shore, the electric-controlled trolley 3 is started to make the platform 4 and the transport vehicle 7 move synchronously to the end of the Bailey beam 2 away from the shore. First, the lifted new Bailey frame is placed on the steel pile 1 to complete the beam installation, and then the electric-controlled trolley 3 is directly moved to the newly erected Bailey beam 2, the boom 5b of the crawler crane 5 is rotated and the steel wire rope 5c is led out to lift the new steel pile 1 in the transport vehicle 7, and the boom 5b is rotated again to lift the new steel pile 1 Insert into the far-end soil and use the vibrating pile hammer 6 to complete the piling work, so as to realize the continuous implementation of beam erection and piling operations in a single round trip. At the same time, through the lateral movement of the crawler wheel 5a on the platform 4 and the rotation of the crawler crane 5 body, the boom 5b of the crawler crane 5 can be extended in the lateral direction of each row of steel piles 1 (this direction is perpendicular to the beam body of the Bailey beam 2) to ensure continuous piling operations in a large longitudinal and lateral operating range;

[0046] S4: As the steel pile 1 array is continuously extended in the beach, shallow water, deep water and other areas, vibratory pile hammers 6 of different sizes are selected according to the geological conditions of different areas to ensure that the exciting force of the vibratory pile hammer 6 drives the steel pile 1 into the design required elevation. The exciting force of the vibratory pile hammer 6 is in direct proportion to the soil hardness and is executed according to the following table:

[0047] Soil level Grade A soil Grade B soil Grade C soil Exciting force(KN) 380～550 550～900 900～1390

[0048] At this time, according to the slope angle formed after the Bailey beam 2 is extended over a long distance, the remote control device is used to centrally control the hydraulic lifting device 3d on each electric control trolley 3, so that the support of multiple hydraulic lifting devices 3d to the platform 4 remains horizontal, and then during the piling and beam erection process, inclined pads are inserted between the platform 4 and the trolley to support it firmly, thereby ensuring the rigid support state of the platform 4 and making the hydraulic lifting device 3d no longer subjected to force, so as to implement safe and stable beam erection and piling operations.

[0049] Embodiment 2

[0050] The present embodiment is different from the first embodiment in that a second water piling mode is provided, the purpose of which is to adapt to the operation requirements under different conditions and improve the synchronous operation efficiency in deep water areas or under the condition that the Bailey beam 2 cannot be installed synchronously.

[0051] The working steps of this embodiment are as follows:

[0052] S1: the same as step S1 in embodiment 1;

[0053] S2: the same as step S2 in the first embodiment;

[0054] S3: When the supply quantity of new Bailey beams 2 is insufficient, or the Bailey beams 2 cannot be implemented synchronously with the piling operation due to the limitation of operation efficiency, the electric control trolley 3 is started to adjust the position of the crawler crane 5, and then the crawler crane 5 is started to rotate its boom 5b to the side closer to the shore. At this time, the Bailey pins connected to the adjacent Bailey frames are removed, and multiple steel wire ropes 5c are pulled out from the end of the boom 5b to carry out the lifting connection of the Bailey frame close to the shore. The boom 5b is restarted to rotate it to the side away from the shore, and the lifted Bailey frame is moved to the top of the steel pile 1 away from the shore. At this time, the steel wire rope 5c is first extended to place the Bailey frame flat on the steel pile 1 and keep lifting. Ensure that the pin holes of the alternating Bailey beam 2 are concentric with those of the adjacent Bailey beam 2, and then insert the Bailey pin to fix the two. At the same time, the upper and lower ends of the Bailey frame are connected and fixed with the connection parts of the cushion beam 3b and the distribution beam 1a respectively through U-shaped bolts (the bolts are removed each time the position of the Bailey beam 2 is changed), and the alternating beam arrangement work is completed. By analogy, the alternating operation of the Bailey beam 2 in step S2 is repeated, and the positions of the two Bailey beams 2 are alternately alternated to implement continuous piling operations on the infinite path ahead, and a barge loaded with new steel piles 1 and accessories is followed in real time as a material supply for the continuous piling operation. At the same time, through the lateral movement of the crawler wheel 5a on the platform 4 and the rotation of the crawler crane 5 body, the boom 5b of the crawler crane 5 can be extended in the lateral direction of each row of steel piles 1 (this direction is perpendicular to the beam body of the Bailey beam 2) to ensure continuous piling operations in a larger operating range in the longitudinal and lateral directions;

[0055] S4: As the steel pile 1 array is continuously extended in the beach, shallow water, deep water and other areas, vibratory pile hammers 6 of different sizes are selected according to the geological conditions of different areas to ensure that the exciting force of the vibratory pile hammer 6 can drive the steel pile 1 into the design required elevation. The exciting force of the vibratory pile hammer 6 can be selected in the range of 380 to 1390 KN, and the magnitude of the exciting force is directly proportional to the soil hardness.

[0056] The alternating beam erection and piling mode adopted in this embodiment has different application fields from the continuous beam erection and piling mode adopted in the first embodiment. The specific reference conditions are as follows:

[0057] Working conditions Adequate supply Insufficient supply Installation out of sync Transport out of sync Initial shore operations Deepwater mid-stream operations Operation Mode Continuous beam Alternating beams Alternating beams Alternating beams Continuous beam Alternating beams

[0058] From the analysis of the classification conditions of the two piling modes in the table, it can be seen that the present invention can be implemented through the transformation of Example 1 and Example 2, and can produce good pertinence and adaptability to different operating conditions, and can be applied to bridge pile foundation construction in various regions and conditions across the country.

[0059] Embodiment 3

[0060] The difference between this embodiment and the first embodiment is that the type of the butt-jointed support structure of the Bailey beam 2 is limited, so as to further improve the bearing performance of the overall structure under various impact conditions.

[0061] like Figure 3 As shown, two adjacent Bailey sheets 2a, upper transverse connecting rods 2b, lower transverse connecting rods 2b and multiple oblique transverse connecting rods 2b together form a truss tube system, wherein the obliquely arranged connecting rods 2b form an oblique network structure system with multiple cross connection structures. At the same time, multiple obliquely arranged connecting bars are also arranged between two transversely adjacent Bailey beams 2, so that the two Bailey beams 2, the distribution beam 1a, the cushion beam 3b and multiple connecting bars together form a truss tube system, thereby forming a double truss tube structure together with the truss tube system of the Bailey beam 2 itself, and the obliquely arranged connecting bars also form an oblique network structure system with a cross connection structure. The pile bodies of the two transversely adjacent steel piles 1 are fixedly connected by multiple obliquely arranged transverse connecting steel sections 1b, so that the two steel piles 1, the distribution beam 1a, the multiple transverse connecting steel sections 1b and the foundation together form a truss tube system, thereby forming a double-layer truss tube structure together with the Bailey beam 2 itself.

[0062] The working principle of this embodiment is as follows:

[0063] When a crawler crane 5 is used to carry out pile driving, beam erection or moving operations, or a transport vehicle 7 is used to carry out transportation work, the truss tube system composed of the Bailey beam 2, the distribution beam 1a, the cushion beam 3b and the connecting ribs and the truss tube system of the Bailey beam 2 itself together form a double truss tube structure, and the tube structure diagonal braces (transverse connecting rods 2b, connecting ribs) are used to resist the lateral load caused by pile driving, beam erection or transportation. The double truss tube has high lateral stiffness in its entirety and in parts. At the same time, the bottom steel piles 1, the distribution beam 1a, the transverse connecting steel 1b and the foundation also form a truss tube system. The upper and lower double layers and the inner and outer double trusses Under the joint action of the tube structure system, the overall bending and shear resistance in the horizontal and vertical directions is improved, ensuring that the operational impact loads generated by beam erection, piling, loading and transportation are directly borne by the foundation. In addition, due to the excellent lateral resistance formed by the overall and local combined truss tube structure, the subsequent use of Bailey beams 2 and steel piles 1 to build bridges can improve the interference resistance to wind and seismic forces. The cross-oblique network structure system composed of transverse connecting rods 2b and connecting bars also has high vertical rigidity and structural seismic resistance for early piling impact and later earthquake impact, thereby improving the overall process quality of bridge construction.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to be a formal limitation. The present invention may also be modified, changed or replaced by equivalents within the scope of the claims, all of which should fall within the protection scope of the present invention.
