Description

Technical Field

[0001] The utility model belongs to the technical field of underwater demolition in water transportation engineering, and particularly relates to an unmanned underwater pile foundation automatic cutting device. Background Technique

[0002] There are two traditional underwater pile foundation demolition techniques. One is to use a breaker to break; the other is for divers to cooperate with a wire saw cutting machine for cutting.

[0003] The process of using a breaker to break the pile foundation is greatly restricted by the pile foundation diameter, breaker power, and working water depth. Moreover, the integrity of the pile foundation to be cut cannot be guaranteed, and the waste residue generated by breaking affects the ecological environment and seriously affects the pile driving construction of the newly built berth in the later stage. Therefore, the breaker breaking process is only applicable to the demolition of pile foundations with a small diameter and a water depth of about 3m. If pile driving is required in this area later, a large amount of cost and time are needed to clean the broken concrete and steel bars underwater.

[0004] The process of divers cooperating with a diamond wire saw for cutting, the specific implementation steps are: divers install a guiding frame underwater → install a diamond cutting wire underwater → multi-functional barge binds the pile → personnel evacuate → the cutting machine runs for a trial → formal cutting → the pile foundation is lifted and removed. This process requires divers to cooperate throughout, and frequent going up and down in the water is needed, which is suitable for construction in areas with relatively shallow water depth and slow flow velocity. If the water depth is large, heavy diving is required. Whether it is light diving or heavy diving, this process has relatively high costs, high safety risks, low efficiency, and is greatly affected by external environmental factors.

[0005] For some construction areas with relatively complex conditions, such as at the estuary of the Guan River, where the river flow velocity reaches 2.0m / s, the maximum cutting water depth is 20m, and new PHC pipe piles need to be driven in the pile cutting area later, and the pile cutting quality requirements are relatively high. The above two conventional demolition techniques are very difficult to meet the requirements. Therefore, we have researched and designed an unmanned underwater pile foundation automatic cutting device. Content of the Utility Model

[0026] Please refer to Figure 2 , the diamond wire saw cutting system includes a wire saw guiding frame 18 provided at the bottom of the truss main body 1. Guide wheels 9 are fixedly installed at the four vertices of the wire saw guiding frame 18 respectively. The guide wheels 9 are driven to rotate by a wire saw cutting main machine 8. A diamond cutting wire 10 is installed in a tensioned manner around the four guide wheels 9; A slide rail mechanism is provided between the truss main body 1 and the wire saw guiding frame 18. The wire saw guiding frame 18 can move back and forth along the truss main body 1. It also includes a guiding frame driving mechanism for driving the wire saw guiding frame 18 to move back and forth.

[0027] The truss main body 1 and the mounting bracket 17 are welded into a whole by 12# channel steel, and the outer surface is sprayed with anti-corrosion metal paint.

[0028] Please refer to Figure 3 , Figure 4 and Figure 6 , the slide rail mechanism includes a group of slide rails 11 symmetrically arranged on both sides of the bottom of the truss main body 1. A first slider 21 is provided at the front end of the wire saw guiding frame 18, and the first slider 21 is slidably installed on the slide rail 11.

[0029] The guiding frame driving mechanism includes a mounting bracket 16 provided at the rear side of the truss main body 1. A group of guide rods 20 are horizontally arranged on the mounting bracket 16. A second slider 17 is fixedly provided at the rear end of the wire saw guiding frame 18, and the second slider 17 is slidably installed on the guide rods 20; A group of sprockets 19 are also provided on the mounting bracket 16. A power chain 13 is installed between the sprockets 19. The power chain 13 is parallel to the guide rods 20. The second slider 17 is connected to the power chain 13, and the sprockets 19 are driven to rotate by a sprocket main machine.

[0030] The wire saw cutting main machine 8 and the sprocket main machine are driven by a hydraulic press 6. The hydraulic press 6 is connected to the wire saw cutting main machine 8 and the sprocket main machine through hydraulic hoses 7 respectively.

[0031] During the use of this equipment, the air compressor 2 and the hydraulic press 6 are placed on the ground and are respectively connected to the underwater pile-holding system and the diamond wire saw cutting system through the air pipe 3 and the hydraulic hose 7 for control. The lengths of the air pipe 3 and the hydraulic hose 7 can be adjusted according to the water depth.

[0032] In this embodiment, a pile foundation anti-tilting rod 12 is further provided in the middle of the wire saw guiding frame 18. The pile foundation anti-tilting rod 12 is parallel to the diamond cutting wire 10, and an insertion piece 15 is provided in the middle of the pile foundation anti-tilting rod 12.

[0033] A linear guide rail 22 is arranged along the length direction at the bottom of the wire saw guide frame 18. Both ends of the pile foundation anti-tilting rod 12 are installed on the linear guide rail 22 through linear bearings and can move along the linear guide rail 22. A spring is sleeved and installed on the linear guide rail 22 in front of the pile foundation anti-tilting rod 12.

[0034] When the diamond cutting wire 10 cuts the pile foundation, a cutting seam will be formed. The pile foundation may tilt due to gravity and water flow fluctuations, which may cause the diamond cutting wire 10 to be stuck and jammed by the cutting seam and unable to work. The pile foundation anti-tilting rod 12 designed by the utility model is located behind the diamond cutting wire 10. After the diamond cutting wire 10 in front cuts, the pile foundation anti-tilting rod 12 behind can be inserted into the cut gap to play a role in supporting and separating. The spring can adjust and control the movement of the pile foundation anti-tilting rod 12 to ensure that the pile foundation anti-tilting rod 12 can be stuck into the cutting seam, effectively avoiding the diamond cutting wire 10 from being stuck and damaging the wire saw system.

[0035] The working principle of the underwater pile foundation automatic cutting equipment involved in the utility model is as follows:

[0036] The underwater pile foundation automatic cutting equipment is hoisted above the pile foundation to be cut off by a lifting device. The top of the pile foundation passes through the hollow of the frame of the truss main body 1. After adjusting the position and direction of the equipment, the lifting device releases the hook and sinks the underwater pile foundation automatic cutting equipment to the specified elevation; start the air compressor to push the pile clamping slot 5 of the pneumatic pile clamping system forward to clamp the pile foundation; start the power supply of the hydraulic diamond wire saw cutting system to start cutting the pile foundation. Please refer to Figure 5 and Figure 6 , the power chain 13 drives the wire saw guide frame 18 to move forward. At the same time, the guide wheel 9 drives the diamond cutting wire 10 to rotate at a high speed. The diamond cutting wire 10 contacts the pile foundation and starts cutting. The guide frame 18 continues to move forward to complete the cutting work of the entire pile foundation. During the cutting process, the pile foundation anti-tilting rod 12 can prevent the diamond cutting wire 10 from being stuck due to the tilt of the cutting seam position of the pile foundation during the cutting process; after cutting, use the lifting device to lift the pile foundation and the underwater pile foundation automatic cutting equipment together to the specified position.

[0037] Through the cooperation of the above equipment, it solves the problem that divers are required to go underwater to remove the pile foundation of high-pile wharves; solves the problem that diving operations are greatly affected by the external environment; solves the problem of low construction efficiency; solves the problems of high cost and high danger of traditional shipping methods.

The scope of the utility model is defined by the appended claims and their equivalents.
