The implementation principle of the positioning device for inserting and driving the steel sheet piles in foundation pit construction is as follows: the driving mechanism drives the positioning table 1 to move along the arrangement direction of the steel sheet piles 100, when the positioning table 1 finishes the positioning and inserting of the steel sheet piles 100 and the sliding pins 52 are flush with the positioning holes 21, under the thrust action of the second springs 54, one ends of the sliding pins 52 are inserted into the positioning holes 21, so that the switching mechanism 55 disconnects the electric circuit of the motor 42, and the motor 42 stops driving the positioning table 1. When the worker slides the slide pin 52 in a direction away from the positioning hole 21 by the push rod 53, the switch mechanism 55 turns on the electric circuit of the motor 42, so that the motor 42 drives the positioning table 1 to move forward until the slide pin 52 is inserted into the next positioning hole 21, the switch mechanism 55 again turns off the electric circuit of the motor 42, stops driving the positioning table 1 again, automatically stops the motor 42 after the positioning table 1 moves forward by the insertion and driving distance of one steel sheet pile 100, and automatically stops the positioning table 1 at the insertion and driving position of the next steel sheet pile 100, thereby improving the positioning accuracy of the positioning table 1.
Because the aperture of the guide surrounding plate 13 gradually increases from bottom to top, when the steel sheet pile 100 is lifted above the guide surrounding plate 13 by the pile driver, the steel sheet pile 100 gradually moves downwards along with the pile driver, so that the bottom end of the steel sheet pile 100 is conveniently inserted into the guide surrounding plate 13, and under the guide effect of the guide surrounding plate 13, the steel sheet pile 100 is driven by the pile driver to move downwards, the steel sheet pile 100 is inserted into the guide hole 121, meanwhile, the connecting plate 12 is rotatably arranged on the platform plate 11, so that the connecting plate 12 can adjust the opening direction of the outline of the guide hole 121 according to the opening direction of the inserted steel sheet pile 100, and a worker does not need to support the bottom of the lifted steel sheet pile 100, thereby reducing the possibility that the hand of the worker is clamped and reducing the risk in the construction process of the worker.
The invention also discloses a steel sheet pile inserting and driving process in foundation pit construction, which comprises the following steps:
s1: the steel sheet pile 100 is inserted and driven by the positioning equipment, starting from the transverse bridge of the cofferdam to the center, then sequentially going to two sides, and finally closing near the downstream corner pile;
s2: detecting and determining the position of the first steel sheet pile 100;
s3: each steel sheet pile 100 is inserted downwards by self weight, and when the steel sheet piles cannot be inserted downwards by self weight, pressurization is carried out;
