Description

Technical Field

[0001] This utility model relates to the field of steel pipe pile construction technology for steel trestle bridges on water. More specifically, this utility model relates to an auxiliary device for driving steel pipe piles using a crane vessel in shallow water. Background Technology

[0002] During the construction of the steel trestle bridge over water, a crane vessel is used to drive the steel pipe piles. The conventional construction procedure for driving steel pipe piles by crane vessel is: pile erection → lifting of vibratory hammer → vibratory hammer clamping of pile → lifting and positioning → driving of steel pipe piles. Due to the low water depth in the construction area, the center of gravity of the steel pipe piles is too high during the pile erection process, posing a significant safety hazard due to the risk of the steel pipe piles tipping over. Previous methods required replacing the crane with one with a crane with a larger lifting capacity and longer boom, or installing a positioning guide frame at the bow. Replacing the crane with crane would increase the project construction cost, and larger crane vessels have lower construction efficiency and are more difficult to position. Installing a positioning guide frame at the bow requires adjusting the vessel's position for each steel pipe pile driven, greatly reducing construction efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an auxiliary device for driving steel pipe piles on a crane vessel in shallow water, so as to solve the technical problem of inconvenience in guiding and erecting steel pipe piles on water in the prior art.

The pile top opening has a fixed opening at one end connected to the top of the supporting foundation and a guide opening at the other end facing the side where the steel pipe pile is to be driven. The front end of the guide opening is hinged with a freely rotating switch door. The inside of the guide opening and the closed switch door work together to limit the horizontal direction and guide the steel pipe pile to be driven in the vertical direction. The work platform is welded to one side of the top of the pile in the width direction, serving as the construction area for operating the opening and closing of the door; The upper and lower passages are welded to the side of the pile top opening facing away from the opening and closing door, with the upper end connected to the working platform and the lower end connected to the deck of the crane ship.

[0017] like Figure 1 , Figure 2 As shown, the auxiliary device for driving steel pipe piles in shallow water using a crane vessel according to this utility model includes: Support foundation 3 is vertically set on crane vessel 1, and the bottom of crane vessel 1 is fixed to the deck side of crane vessel 1 near the side of the steel pipe pile to be driven. The pile top opening 4 has a fixed opening 5 connected to the top of the supporting foundation 3 at one end and a guide opening 6 set towards the side of the steel pipe pile 2 to be driven at the other end. The front end of the guide opening 6 is hinged to a freely rotating switch door 7. The inner side of the guide opening 6 and the closed switch door 7 together limit the horizontal direction and guide the steel pipe pile 2 to be driven in the vertical direction. The working platform 9 is welded to one side of the pile top opening 4 in the width direction, serving as the construction area for operating the opening and closing door 7; The upper and lower passage 10 is welded to the side of the pile top opening 4 facing away from the opening and closing door 7, with its upper end connected to the working platform 9 and its lower end connected to the deck of the crane ship 1.

[0018] The supporting foundation 3, pile top opening 4, and working platform 9 utilize steel pipe piles, I-beams, and channel steel 11 as main components. A self-made supporting foundation 3 pile frame is welded to the edge of the crane vessel 1 deck. The pile top opening 4 is fixed at the top and raised to the required appropriate height. The pile top opening 4 has two parts: one end, the fixed opening 5, is used for fixed connection with the supporting foundation 3; the other end, the guide opening 6, extends beyond the edge of the crane vessel 1 deck to control the verticality of the steel pipe piles 2 and assist in pile stabilization. The guide opening 6 is 10cm larger than the steel pipe piles to be driven on each side of the opening / closing door 7. The front end of the guide opening 6 is also... Figure 1 As shown on the right end, a switch door 7 that can be opened / closed and temporarily fixed is set using a pin 8 to temporarily limit the position on both the front and rear sides in the direction of the switch door 7. This is also shown on the back of the supporting base 3. Figure 1 The ladder shown on the left serves as the access passage 10 for personnel to go up and down. The working platform 9 on one side of the width direction of the pile top opening 4 serves as the operating platform for personnel to unfasten and operate the door 7 on the top of the supporting foundation 3.

[0019] Before using the auxiliary device for driving steel pipe piles on a crane vessel in shallow water, a support foundation 3 is first set up. The height of the support foundation 3 can be selected according to the actual water depth and barge deck height at the construction site. The support foundation 3 is installed on the side of the deck of the crane vessel 1, and the bottom of the support foundation 3 is fully welded to the deck of the crane vessel 1. The crane vessel 1 lifts the steel pipe pile 2 to be driven by binding the piles and then transports it to the support foundation 3. The steel pipe pile is then sent into the guide opening 6. The workers climb up and down the passage 10 into the work platform 9, close the switch door 7, and assist in the erection of the steel pipe pile 2. The steel pipe pile 2 is vertically guided by the guide opening 6. After it is stabilized in the soil under its own weight, the steel wire rope binding the pile is released. The crane vessel 1 lifts the vibratory hammer and clamps the steel pipe pile 2 with the vibratory hammer pile clamp. Then, the switch door 7 of the guide opening 6 is opened, and the steel pipe pile 2 is lifted out of the guide opening 6 for subsequent positioning and driving work.

[0020] The auxiliary device for driving steel pipe piles on a crane vessel in shallow water in this embodiment utilizes a pile frame to control the verticality of the piles and improve the stability of the steel pipe piles. This effectively solves the safety problem of driving long piles on a crane vessel 1 in shallow water, while reducing the requirements for key parameters such as the crane vessel 1's lifting performance and boom length. Using this auxiliary device, multiple steel pipe piles can be driven in a single positioning of the crane vessel 1, effectively improving construction efficiency and significantly shortening the construction period. The pile frame is fabricated using on-site materials to form a supporting foundation 3 and installed on the side of the vessel. The pile top opening 4, working platform 9, and upper and lower passages 10 are welded on. The installation is simple and disassembly is convenient. After use, all materials can be recycled, resulting in high material utilization. This has certain significance for green environmental protection, energy conservation, and material reduction.

[0021] In another technical solution, such as Figure 1-2As shown, the pile top opening 4 is a rectangular frame structure formed by welding multiple I-beams in a horizontal plane. The fixed opening 5 is a closed rectangular frame structure, and the guide opening 6 is an open C-shaped frame structure at the front end, which is temporarily closed by the opening and closing door 7.

[0022] The I-beams are welded along the longitudinal and transverse directions to form a rectangular frame structure. One side of the closed rectangular frame is the fixed opening 5, and the other side of the open rectangular frame is the guide opening 6. The opening of the guide opening 6 is connected to the switch door 7 by a pin 8 to quickly process and manufacture the rapid pile top opening 4. The side of the I-beam structure is easy to weld and fix to the working platform 9, the supporting foundation 3, etc.

[0023] In another technical solution, such as Figure 1-2 As shown, the supporting foundation 3 includes a vertically arranged steel pipe pile structure. A vertically extending channel steel 11 is welded to the outer wall of the upper end of the steel pipe pile structure. The outer side of the channel steel 11 is welded and fixed to the inner side of the pile top opening 4 at the corresponding position. The addition of the channel steel 11 increases the welding contact surface between the fixed opening 5 and the steel pipe pile.

[0024] In another technical solution, such as Figure 1 As shown, the bottom of the supporting foundation 3 is fully welded to the deck of the crane ship 1 and is securely fixed with ribs.

[0025] In another technical solution, such as Figure 2 As shown, the edge of the work platform 9 is connected to a guardrail 12, and the bottom of the guardrail 12 is connected to a kick plate 13. The guardrail 12 is arranged on the outside of the ladder to improve the safety of workers going up and down and assisting in construction on the work platform 9.

[0026] In another technical solution, such as Figure 1-2 As shown, the top of the pile opening 4 is positioned higher than the top of the working platform 9. A stop 14 is provided at the end of the guide opening 6 away from the hinge, corresponding to the closing end position of the switch door 7. Limiting holes 15 are respectively provided on the outer end of the switch door 7 and the guide opening 6 at the outer end where the stop 14 is located. A limiting member 16 is inserted downward into both limiting holes 15 to temporarily fix the switch door 7. The limiting holes 15 and the limiting member 16 can be configured as a combination of a plug and a pin, or a combination of a screw hole and a bolt. When the switch door 7 rotates around the hinge pin 8 to abut the stop 14, it is limited. The two limiting holes 15 are vertically aligned. Then, the limiting member 16 is inserted to horizontally limit and fix the position of the switch door 7 when it is closed.

[0027] In another technical solution, such as Figure 2As shown, the top of the switch door 7 is provided with a sliding groove 17 along its length. The working platform 9 is provided with a sliding rod 18. One end of the sliding rod 18 is a hand-held part, and the other end is hinged downwards to a sliding ball. The sliding ball can slide relative to the sliding groove 17. The length of the sliding rod 18 is not less than the outer diameter of the steel pipe pile. The sliding rod 18 has a certain length. After the switch door 7 is opened and the steel pipe pile is introduced, the switch door 7 is far from the working platform 9. The end of the sliding rod 18 with the sliding ball is extended into the sliding groove 17, and the sliding rod 18 is pulled, thereby pulling the switch door 7 to rotate in the closing direction until it rotates and hits the stop block 14. The limiting piece 16 is inserted under a pair of limiting holes 15 to determine the verticality of the steel pipe pile. When the steel pipe pile is being worked on, the sliding rod 18 is retracted upwards, the limiting piece 16 is removed, and the switch door 7 is released from the closed state. The switch door 7 can also be opened by pushing it open through the sliding rod 18 to facilitate the subsequent driving and movement of the steel pipe pile.

[0028] The auxiliary device for driving steel pipe piles using a crane vessel in shallow water can be constructed using the following steps: ① For steel pipe pile foundations, steel pipe pile segments are selected as the foundation. The height of the steel pipe piles can be selected according to the actual water depth and barge deck height at the construction site.

[0029] ② Weld channel steel 11 on both sides of the top of the steel pipe pile to increase the contact surface between the I-beam slit and the steel pipe pile. Weld the I-beam slit to the steel pipe pile. The dimensions of each side of the slit are increased by 10cm compared to the steel pipe pile to be driven. A switchable limit device is processed at the front end of the slit using a pin 8.

[0030] ③ Weld a ladder to the back of the pile frame and a working platform 9 to the side to form the pile frame. The working platform 9 is 80cm wide. 1.2m high guardrails 12 are set on both sides of the working platform 9 and 18cm high kickboards 13 are set at the bottom.

[0031] ④ The pile frame is transported to the crane vessel 1 for installation. It is installed on the side of the deck of the crane vessel 1. The bottom of the pile is fully welded to the deck of the crane vessel 1 and fixed with ribs. The crane vessel 1 lifts the steel pipe pile 2 by binding the pile and then lifts the steel pipe pile 2 to the pile frame. The steel pipe pile 2 is sent into the guide auger 6. Personnel enter the work platform 9 through the ladder and close the switch door 7 to complete the erection of the steel pipe pile 2. After the steel pipe pile 2 stabilizes in the soil by its own weight, the wire rope is released. The crane vessel 1 lifts the vibratory hammer and uses the vibratory hammer pile clamp to clamp the steel pipe pile 2. Then, the switch door 7 is opened and the steel pipe pile 2 is lifted out of the guide auger 6 for subsequent positioning and driving work.

[0032] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
