[0022] Embodiment 1: A limiting guide device for steel sheet pile sinking: comprising a guide frame 1 and a steel sheet pile 9, wherein an upper guide template 2 and a lower guide template 6 are respectively provided on the upper and lower sides of the guide frame 1, and an avoidance hole 3 for accommodating the upper guide template 2 and the lower guide template 6 is opened in the middle of the guide frame 1. The upper guide template 2 and the lower guide template 6 have the same structure and both include a first guide plate and a second guide plate. The first guide plate and the second guide plate are directly fixedly connected to the guide frame 1, or, in order to improve the convenience of use, the first guide plate and the second guide plate can be detachably connected to the guide frame 1, through The bolts are detachable and connected, which makes it easy to replace the upper guide template 2 and the lower guide template 6 of different shapes and specifications, and adapt to different types of steel sheet piles 9. A pile groove adapted to the steel sheet piles 9 is provided between the first guide plate and the second guide plate, which is used to pass the steel sheet piles 9, and the upper guide template 2 and the lower guide template 6 cooperate to limit and guide the installation of the steel sheet piles 9. Then the vibrating hammer is used to vibrate and sink the steel sheet piles. A telescopic tube 4 is provided at the bottom of the guide frame 1, and a ball is provided at the bottom of the telescopic tube 4. When the ball is extended, it is easy to move. When the ball is retracted, the telescopic tube 4 is embedded in the mud and sand for fixation.

[0023] Example 2, reference Figure 1-4 A limiting guide device for steel sheet pile driving includes a guide frame 1 and a steel sheet pile 9. An upper guide template 2 and a lower guide template 6 are provided on the upper and lower sides of the guide frame 1, respectively. The upper guide template 2 and the lower guide template 6 have the same structure and both include a first guide plate and a second guide plate. A relief hole 3 for accommodating the upper guide template 2 and the lower guide template 6 is provided in the middle of the guide frame 1. A pile groove adapted to the steel sheet pile 9 is provided between the first guide plate and the second guide plate.

[0024] The guide frame 1 is provided with a slide rail 7, and the slide rail 7 is provided with multiple groups, which are respectively arranged corresponding to the upper guide template 2 and the lower guide template 6. The slide rail 7 is specifically arranged at both ends of the first guide plate and the second guide plate. The first guide plate and the second guide plate are in sliding contact with the slide rail 7;

[0025] A control device 5 is provided on both sides of the upper guide template 2 and the lower guide template 6. The control devices 5 on both sides are respectively arranged corresponding to the first guide plate and the second guide plate. The control device 5 can control the first guide plate and the second guide plate to move closer to or farther away from each other and be fixed at any point. The control device 5 is generally a screw device, a linear motor or a hydraulic telescopic rod. The shell or the machine base is fixedly connected to the guide frame 1, and the output end is connected to the first guide plate or the second guide plate, which is used to control the first guide plate or the second guide plate to slide on the slide rail 7 to adjust the width of the pile groove, so that the operator can place the steel sheet pile 9 and improve the convenience of operation. Or when the steel sheet pile 9 is stuck, it can be quickly released to facilitate the staff to adjust and repair or replace the steel sheet pile 9. After that, the first guide plate or the second guide plate can be controlled to move closer to each other to limit the steel sheet pile 9, which is convenient for subsequent pile sinking construction.

[0026] A protective frame 8 is provided on the upper side of the guide frame 1. The protective frame 8 is welded with steel bars to facilitate construction workers to lift or control the movement of equipment, while protecting construction workers from getting close to the steel sheet pile 9 construction environment to avoid safety accidents.

[0027] A telescopic tube 4 is provided at the bottom of the guide frame 1, and a ball is provided at the bottom of the telescopic tube 4. The middle of the telescopic tube 4 is connected by a thread, which is convenient for disassembly and assembly and adjustment of the height of the telescopic tube 4. The ball is movably connected to the bottom end of the telescopic tube 4.

[0028] In this embodiment, before the guide frame 1 is placed, a total station is used to measure and lay out the position of the steel sheet pile 9. White lime or other tools can be used to mark it to facilitate subsequent placement. The guide frame 1 is placed according to the marked position. To prevent the guide frame 1 from shifting during the construction of the steel sheet pile 9, the telescopic tube 4 is inserted into the soil layer to fix the guide frame 1.

[0029] When the steel sheet piles 9 are inserted, a screen-type driving method is adopted, that is, 10 to 20 steel sheet piles 9 are inserted into the pile grooves on the upper guide template 2 and the lower guide template 6 in a row by means of a crane, and the crane is slowly lowered. After the pile body is stable, the steel sheet piles 9 are vertically contacted with the ground by their own weight. In the first embodiment, the position of the steel sheet piles 9 is generally fine-tuned by using iron wedges or the like. In the second embodiment, the first guide plate and the second guide plate are adjusted by means of the control device 5 to change the size and position of the pile groove. After the pile position error is finally determined to be within the allowable deviation range, the vibratory hammer is started to start vibrating and sinking the steel sheet piles 9;

[0030] During the driving process, the measurement work is strengthened. If tilt is found, timely adjustment is made through the control device 5. After the pile is vertically inserted to the designed elevation, the pile is stopped and the above operation is repeated until the construction of the steel sheet piles 9 that can be constructed in the guide frame 1 is completed. Use a crane or other machinery to lift out the guide frame 1 and move it to the next construction section.
