[0022] At one end of the two long crossbeams, a first short crossbeam 102 is connected; both ends of the first short crossbeam 102 are vertically connected and fixed to the end faces of the two long crossbeams; a circular positioning pile hole 2 that penetrates up and down is centrally opened on the first short crossbeam 102, and the inner diameter of the positioning pile hole 2 is adapted to the outer diameter of the positioning pile 3, so that the positioning pile 3 is vertically inserted into the positioning pile hole 2, and the positioning pile is located on the central axis of the guiding frame main body 1; the positioning pile 3 is preferably a steel pipe pile.

[0023] At the other ends of the two long crossbeams, an inverted U-shaped frame 103 is connected; the inverted U-shaped frame 103 is specifically composed of two short vertical beams arranged in parallel and a second short crossbeam vertically fixed at the tops of the two short vertical beams, and the bottoms of the two short vertical beams are respectively fixed on the end faces of the two long crossbeams 101; wherein, the inner width of the inverted U-shaped frame 103 (i.e., the distance between the two short vertical beams) is greater than the width of the pipe pile, so that the inverted U-shaped frame 103 can be erected on the pipe pile that has been driven; in practical applications, one end of the guiding frame main body 1 is positioned by being erected on the pipe pile that has been driven, and the other end is positioned by the positioning pile 3 inserted on the first short crossbeam 102, so that the guiding frame main body 1 is arranged along the designed extension direction of the prestressed pipe pile. Furthermore, with the assistance of the guiding frame main body 1, the prestressed pipe piles inserted into the guiding frame main body 1 can be driven in sequence along the designed extension direction.

Specifically, the long crossbeam 101 is arranged with the through groove opening upwards, and the first short crossbeam 102 is arranged with the opening downwards; the inverted U-shaped frame 103 is cut from three I-shaped steels and welded and fixed; the long crossbeam 102 and the inverted U-shaped frame 103, as well as the long crossbeam 101 and the short crossbeam 102, are welded and fixed into a whole.

[0025] See Figure 3 , the main limiting mechanism includes a main limiting plate 4, which horizontally spans between the two long crossbeams 101; both ends of the main limiting plate 4 in the width direction of the long crossbeam 101 are fixed at any position in the length direction of the two long crossbeams 101 in a position-adjustable manner through a set of movable connection components; specifically, the movable connection component is composed of a zipper 7 and a limiting pin 8; wherein, the zipper 7 is composed of a plurality of vertically arranged cylindrical short tubes connected in sequence, and it is arranged along the length direction of the long crossbeam 101 and fixed on the inner wall surface of the inner groove wall of the long crossbeam 101; an axial pin hole 6 is opened on the main limiting plate 4 above the zipper 7, so that during the process of the axial pin hole 6 moving in the length direction of the long crossbeam 101 along with the main limiting plate 4, it can be respectively arranged in alignment with each cylindrical short tube one by one; the outer diameter of the cylindrical short tube is greater than the outer diameter of the limiting pin 8, and the upper side of the limiting pin 8 is inserted and fixed in the axial pin hole 6 of the main limiting plate 4; furthermore, by inserting the limiting pin 8 into any cylindrical short tube on the zipper 7, the main limiting plate 4 is temporarily fixed at any position on the long crossbeam 101.

[0026] On the end side of the main limit plate 4 close to the inverted U-shaped frame 103, a main auxiliary roller 5 is provided. It is arranged along the width direction of the long cross beam 101 and is rotatably arranged on the main limit plate 4 through a roller bracket, so that the main limit mechanism abuts against the side wall of the pipe pile through the main auxiliary roller 5, forming a rolling contact between the main limit mechanism and the side wall of the pipe pile, and reducing the friction between the main limit mechanism and the side wall of the pipe pile. Furthermore, during the driving of the pipe pile, the main auxiliary roller 5 in contact with the pipe pile wall surface rolls freely longitudinally, playing a role in limiting and straightening the pipe pile.

Furthermore, during the driving of the pipe pile, the three side auxiliary rollers 13 in contact with the outer wall of the pipe pile roll freely longitudinally, playing a role in limiting and straightening the pipe pile.

Then insert the positioning piles 3 into the mud surface along the positioning pile holes 2, so that the guide frame body 1 is set along the design direction of the pipe pile and horizontally fixed on the mud surface. Furthermore, through the positioning function of the inverted U-shaped frame 103 of the guide frame body 1 and the positioning piles 3 arranged in the positioning piles 2, the channel between the two long crossbeams 101 is a horizontal guide channel laid in the horizontal direction. That is, in subsequent pile foundation construction, pile foundation construction can be carried out by sequentially introducing new pipe piles along the horizontal guide channel.

[0031] S2. Hoist a new prestressed U-shaped pipe pile into the guide groove formed between the two long crossbeams 101, adjust the position of the main limit plate 4 on the main limit mechanism on the two long crossbeams 101 so that its main auxiliary rollers 5 abut against the side wall of the new prestressed U-shaped pipe pile. Then, by vertically inserting the two limit pins 8 on the main limit plate 4 into the corresponding cylindrical short tubes in the zipper 7 respectively, the position of the main limit mechanism is fixed. Next, adjust the positions of the two side limit nuts 11 of the side limit mechanism on the threaded section of the limit rod 10 so that the limit rod 10 can move in the side limit hole channel 9 until the side auxiliary rollers 13 on its side limit plate 12 abut against the back side wall surface of the new prestressed U-shaped pipe pile. Then, fix the position of the limit rod 10 through the two side limit nuts 11. Furthermore, use the main limit mechanism and the side limit mechanism to enclose a vertical guide channel adapted to the size of the prestressed U-shaped pipe pile with the two long crossbeams 101 and the inverted U-shaped frame 103. Carry out driving operations on this new prestressed U-shaped pipe pile until the preset elevation position.

[0032] S3. Release the connection and fixation relationship between the main limit mechanism and the side limit mechanism and the two long crossbeams 101 respectively, and move horizontally towards the side of the positioning pile 3 to reserve the lowering position of the new prestressed U-shaped pipe pile. Repeat step S2 to complete the driving operation of the new prestressed U-shaped pipe pile.
