[0025] A steel pipe pile guide frame according to an embodiment of the present specification is described in detail below with reference to the accompanying drawings. Figure 1 A structural schematic diagram of a steel pipe pile guide frame of an embodiment of the present specification is shown. The present specification provides a steel pipe pile guide frame, comprising: a frame body, a bracket 2 and a guide cylinder 3 for placing steel pipe piles; the frame body comprises a first support portion 11 and a second support portion 12 arranged in parallel and spaced apart, and a connecting member 13 connecting the first support portion 11 and the second support portion 12 and movable along the length direction of the first support portion 11 and the second support portion 12 or perpendicular to the length direction; the connecting member 13 is provided with a bracket 2 movable along a length direction perpendicular to the connecting member 13; the guide cylinder 3 is built into the bracket 2.
[0026] The first support part 11 and the second support part 12, which are arranged in parallel and have equal length, are fixed at one end top by a crossbeam. The crossbeam can be an I-shaped, L-shaped, or concave-shaped channel steel, preferably a concave-shaped channel steel. The notch of the channel steel faces away from the first support part 11 and the second support part 12. The number of the crossbeams is not limited, but preferably 2. The two crossbeams are arranged in parallel and spaced on the first support part 11 and the second support part 12, and the parallel spacing distance between the two crossbeams is greater than 2m and less than half of the length of the first support part 11 or the second support part 12.
[0027] The connecting member 13 is a concave channel steel, the notch of the channel steel faces the first supporting portion 11 and the second supporting portion 12, and the two ends of the connecting member 13 are provided with bayonet holes 14 that are engaged with the first supporting portion 11 and the second supporting portion 12. The connecting member 13 drives the bracket 2 and the guide cylinder 3 to move along the length direction of the first supporting portion 11 and the second supporting portion 12 through the bayonet holes 14. The width of the bayonet holes 14 is slightly larger than the width of the first supporting portion 11 or the second supporting portion 12, so that the connecting member 13 is just engaged with the first supporting portion 11 and the second supporting portion 12, and can also move along the length direction of the first supporting portion 11 and the second supporting portion 12.
[0028] Figure 2 Shows Figure 1 Schematic diagram of the middle stopper. A stopper 15 is provided on the side of the bayonet 14. The number of the stoppers 15 is not limited, but in order to prevent the connecting member 13 from driving the bracket 2 and the guide cylinder 3 to move during operation, the number of the stoppers 15 shall not be less than 4. The stopper 15 must be installed on the side of the bayonet 14 close to the connecting member 13.
[0029] The first support portion 11 and the second support portion 12 are I-shaped, which can be a single I-shaped or a double I-shaped. Considering that the first support portion 11 and the second support portion 12 serve as supporting components of the entire guide frame, a double I-shaped shape with better supporting capacity is preferred.
[0030] The stopper 15 includes a buckle and a first bolt, the buckle is engaged with the upper wing plates of the first support part 11 and the second support part 12, and the first bolt is tightened to fasten the stopper 15 to the first support part 11 and the second support part 12. The buckle can be moved to any designated piling position of the first support part 11 and the second support part 12 by loosening the first bolt.
[0031] Figure 3 Shows Figure 1Schematic diagram of the fixing member. The connecting member 13 and the bracket 2 are fixed by a fixing member 21. The fixing member 21 includes a second bolt and a nut. The second bolt is passed through the connecting member 13 and the bracket 2, and the nut is tightened, so that the bracket 2 is fastened to the connecting member 13; the nut is loosened, and the bracket 2 and the guide cylinder 3 can move in a direction perpendicular to the length of the connecting member 13; the nut is unscrewed, and the bracket 2 and the guide cylinder 3 are moved upward along the second bolt to realize the disassembly of the bracket 2 and the guide cylinder 3, so as to reduce the difficulty of transporting the overall guide frame.
[0032] The connecting member 13 and the bracket 2 are provided with holes matching the second bolts. When fixing the connecting member 13 and the bracket 2, the second bolts are sequentially passed from the bottom of the connecting member 13 to the bracket 2, and the bracket 2 is fastened by tightening the nut. Considering that the bracket 2 must be fastened to the connecting member 13 to prevent the guide tube 3 from shifting when the steel pipe pile is placed, the number of the fixing members 21 must be 4 or more.
[0033] Walkway boards 16 are respectively provided on the lower wing plates on the outer sides of the first support part 11 and the second support part 12. The outer sides of the walkway boards 16 are respectively connected to the waist boards of the first support part 11 and the second support part 12 through tie rods 17, and the tie rods 17 fix the walkway boards 16 on both sides of the first support part 11 and the second support part 12. Guardrails 18 are also provided on the outer sides of the walkway boards 16 to prevent workers from falling on the walkway boards 16.
[0034] The guide cylinder 3 is a hexahedral structure whose side surfaces are composed of the same isosceles trapezoids. The upper surface and the lower surface of the guide cylinder 3 are provided with openings opposite to each other in the center. The opening of the upper surface is larger than the opening of the lower surface. The openings of the upper surface and the lower surface are square structures of different sizes. The design structure of the guide cylinder 3 can reduce the influence of the swaying of the hull and the wind and waves at sea on the insertion of steel pipe piles. The opening of the lower surface is set according to the diameter of the steel pipe pile, and the guide cylinder 3 is connected to the bracket 2 through the edge of its upper surface. The bracket 2 is a hollow rectangular parallelepiped structure. The upper surface of the guide cylinder 3 is connected to the upper edge of the bracket 2, and the lower surface of the guide cylinder 3 is connected to the bracket 2 through an angle steel.
[0035] The following is a further explanation of its usage.
[0036] After the steel pipe pile is lifted vertically by the floating crane, it is moved to the top of the guide cylinder 3. When the bottom of the steel pipe pile is within the opening range of the upper surface of the guide cylinder 3, the steel pipe pile is lowered so that the steel pipe pile sinks into the sea from the guide cylinder 3. When lowering, the verticality of the steel pipe pile must be paid attention to at all times, and the position of the hook must be constantly fine-tuned to ensure that the steel pipe pile is lowered vertically.
[0037] When the steel pipe pile cannot continue to sink by its own gravity, release the hook, lift the vibrator, insert the jaws into the top of the steel pipe pile, turn on the vibrator, and start the piling operation. During the piling process, you must always pay attention to the verticality of the steel pipe pile and constantly fine-tune the position of the vibrator to ensure that the steel pipe pile is driven vertically. After the steel pipe pile is driven to the predetermined depth, turn off and remove the vibrator to complete the driving of the first steel pipe pile.
[0038] When the second or nth steel pipe pile is driven, after the previous pile driving is completed, the first bolt is loosened so that the limiter 15 does not temporarily perform the limiting work, and the limiter 15, the bracket 2 and the guide cylinder 3 are moved to the next pile driving position. After the position is determined, the first bolt is tightened to realize the positioning of the bracket 2 and the guide cylinder 3, and the above operation is repeated.
