[0002] The construction of underwater projects such as bridges and ports often requires the construction of temporary structures such as trestles, construction platforms or docks in the water. These temporary structures usually use driven steel pipe piles as the structural bearing foundation. The steel pipe piles are often used for a long time in water. In some geological conditions with poor geological conditions, such as deep silt layers or clay layers, the steel pipe piles need to be driven into a deeper depth to meet the bearing capacity. When the temporary structures are demolished later, it is very difficult to pull out the steel pipe piles. Some steel pipe piles are difficult to pull out and can only be cut underwater. However, underwater cutting is carried out by divers underwater with special cutting equipment. Underwater construction has high safety risks and high construction costs. Utility Model Content

[0025] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0026] In view of the difficulty and risk of underwater cutting of steel pipe piles, this application provides an underwater steel pipe pile cutting system. Figure 1 and Figure 2 The underwater steel pipe pile cutting system does not require divers to perform underwater cutting, which can solve the problems of high safety risks and high construction costs in conventional underwater steel pipe pile cutting operations. It is easy to operate and has high construction efficiency.

[0027] The underwater steel pipe pile cutting system includes a rope saw 1 and an underwater cutting guide platform 2. The rope saw 1 includes a saw rope 11 and a power member 12 arranged on the shore. The saw rope 11 is connected to the power member 12 so that the saw rope 11 can be retracted and released through the power member 12, thereby realizing the cutting of the steel pipe pile. The underwater cutting guide platform 2 includes a guide frame 21 and a guide wheel 22 arranged on the guide frame 21. The saw rope 11 passes through the guide wheel 22 and forms a ring structure with the guide frame 21 to embrace the steel pipe pile to be cut. At the same time, the guide frame 21 is connected to a hoisting member for hoisting the guide frame 21 in a vertical direction. That is, the present application gradually lowers the underwater cutting guide platform 2 along the outer wall of the steel pipe pile to the part to be cut of the steel pipe pile through the hoisting member, and the power member 12 tightens the saw rope 11 so that the underwater cutting guide platform 2 is close to the steel pipe, and then the steel pipe pile is cut by continuously tightening the saw rope 11 until the steel pipe pile is cut off, thereby completing the underwater steel pipe pile cutting operation.

[0028] Please combine Figure 2 The guide frame 21 includes a vertical surface 211 and a plane 212 connected to each other vertically, wherein the vertical surface 211 is used to abut against the outer wall of the steel pipe pile to be cut, so that the plane 212 is arranged parallel to the steel pipe pile, and the guide wheel 22 is arranged on the plane 212, and the guide wheel 22 includes a vertical guide wheel 221 with an axial direction in the vertical direction and a transverse guide wheel 222 with an axial direction in the horizontal direction, and the outer contours of the vertical guide wheel 221 and the transverse guide wheel 222 are tangent. In addition, the guide wheels 22 in this embodiment are arranged in a group on both sides of the plane 212, and guide holes (not shown in the figure) for the saw rope 11 to pass through are also arranged on both sides of the guide frame 21, and the transverse guide wheels 222 of each group of guide wheels 22 are arranged close to the guide holes on the same side. The saw rope 11 can first pass through the vertical guide wheel 221 and then the transverse guide wheel 222 from the shore to the underwater, so as to adjust the direction of the saw rope 11 from the vertical direction to the horizontal direction, thereby cutting the steel pipe pile in the transverse direction.

[0029] In addition, the guide frame 21 of the present application is lowered into the water along the outer wall of the steel pipe pile by a lifting member, and the lifting member can be selected as a lifting rope connected to the guide frame 21, and two lifting ropes are provided and respectively connected to the two ends of the top side of the facade 211. The guide frame 21 is connected by a lifting rope, which has high lifting toughness, small volume, light weight and convenient turnover.

[0030] The rope saw 1 of the present application adopts an electric rope saw 1, and its power part 12 includes an electric rope saw machine body connected to both ends of the saw rope 11. The electric rope saw machine body is arranged on the shore, and the two ends of the saw rope 11 are respectively connected to two driving wheels inside the electric rope saw machine body. The driving wheels are driven to rotate by a motor to realize the retraction and extension of the saw rope 11.

[0031] Furthermore, a guide wheel 3 is provided on the shore where the straight-line distance of the electric rope saw machine body is the shortest. The saw rope 11 passes through the guide wheel 3 from the electric rope saw machine body and is then connected to the underwater cutting guide platform 2. This can avoid direct contact and friction between the saw rope 11 and the shore, thereby improving the durability of the saw rope 11. At the same time, it can guide the saw rope 11 and improve the cutting stability of the saw rope 11.

[0032] When constructing the underwater steel pipe pile cutting system of the present application, the underwater cutting guide platform 2 can be made of small channel steel (or other types of steel) and steel plates according to the diameter of the underwater steel pipe pile to be cut, which is convenient for on-site material acquisition and production. Then, the guide wheel 22 for guiding the saw rope 11 is installed on the plane 212 of the underwater cutting guide platform 2. The guide wheel 22 needs to convert the running direction of the saw rope 11 from the vertical direction to the horizontal direction to meet the requirements of the saw rope 11 for horizontal cutting of the steel pipe pile. At the same time, the distance between the cutting position of the steel pipe pile and the electric wire saw machine body of the onshore wire saw 1 is calculated in advance, the wire direction of the wire saw 1 is planned, and the saw rope 11 of a suitable length is set according to the above calculated distance. The saw rope 11 is connected to the underwater cutting guide platform 2 through the guide wheel 3 on the shore, and the saw rope 11 is sleeved on the steel pipe pile through the underwater cutting guide platform 2.

[0033] After the wire saw 1 is connected to the underwater cutting guide platform 2, the guide frame 21 is gradually lowered along the outer wall of the steel pipe pile to the underwater cutting position of the steel pipe pile by the lifting rope, and then the lifting rope is fixed to fix the vertical position of the underwater cutting guide platform 2. At the same time, the top of the steel pipe pile is lifted in advance by a lifting device to prevent the steel pipe pile from tipping over after cutting.

[0034] Next, the wire saw 1 is started, and the electric wire saw machine body winds up the wire 11 to cut the steel pipe pile. After the wire 11 is tightened, it will be tightly held on the steel pipe pile together with the underwater cutting guide platform 2. The steel pipe pile is continuously cut by continuously tightening the wire 11 until the steel pipe pile is cut off. The steel pipe pile is cut underwater, and the top steel pipe pile is lifted by the lifting equipment and transported away. At the same time, the underwater cutting guide platform 2 and the connected wire 11 are lifted by the lifting rope and left together. Since the cutting surface of the wire saw 1 is underwater, there is no need to spray water for cooling, which reduces the setting of cooling equipment.

[0035] In summary, the underwater steel pipe pile cutting system of the present application adopts an underwater cutting guide platform 2 located underwater and cooperates with a rope saw 1 set up on the shore to realize the underwater cutting operation of the steel pipe pile, which solves the problems of high safety risks and high construction costs in conventional underwater steel pipe pile cutting operations. It is convenient to obtain materials and greatly reduces the construction cost. There is no need for workers to dive underwater to cut steel pipe piles. It is only necessary to operate the lifting rope on the shore to lower the underwater cutting guide platform 2 along the outer wall of the steel pipe pile to the place where the steel pipe pile is to be cut. The cutting of the steel pipe pile is achieved by tightening the saw rope 11. The operation is simple and the construction efficiency is greatly improved.

[0036] The above description is only a partial implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
