The space between the inner shell plate 4 and the outer shell plate 5 of the cofferdam is filled with cofferdam fillers after water is pumped out. The cofferdam fillers include concrete and sand, which are used to fix the positions of the inner shell plate 4 and the outer shell plate 5 of the cofferdam to avoid tilting or overturning, and at the same time increase the supporting force of the inner shell plate 4 and the outer shell plate 5 of the cofferdam to improve the bearing capacity of the cofferdam.

[0051] (2) Secondly, multiple layers of cofferdam horizontal support plates 3 are respectively fixed to the inner walls of the inner shell plates 4 of the cofferdam. Second screws 10 are respectively and pre-fixed and installed on each cofferdam horizontal support plate 3. Multiple cofferdam horizontal support plates 3 on the same layer are respectively connected end to end to form a rectangular support frame. The second screws 10 of the cofferdam horizontal support plates 3 of the rectangular support frame are respectively clamped with the first bolt holes on the side plates of the connecting horizontal support plate 2. The nut installation mechanism 8 automatically installs nuts 30 on each second screw 10. The second screws 10 and the nuts 30 fixedly connect the cofferdam horizontal support plates 3 with the side plates of the connecting horizontal support plate 2. The first screws 9 on the vertical support piles 1 are clamped with the second bolt holes on the bottom plates of multiple connecting horizontal support plates 2 in the same vertical direction. The nut installation mechanism 8 automatically installs nuts 30 on each first screw 9. The first screws 9 and the nuts 30 fixedly connect the vertical support piles 1 with the bottom plates of the connecting horizontal support plate 2. At the same time, the traveling mechanism 6 on the vehicle body 18 travels on the connecting horizontal support plate 2. The position of the nut installation mechanism 8 on the vehicle body 18 in the horizontal direction is adjusted. The abutting rolling mechanisms 7 respectively abut and roll against the side edges of the top plates of the connecting horizontal support plate 2 and the bottom of the top plates. The output shaft of the seventh motor 26 drives the fifth gear 27 to rotate through the sixth connecting shaft. The fifth gear 27 is driven by meshing with the second gear ring 16. The fifth gear 27 rotates in the second gear ring 16. The sixth connecting shaft on the fifth gear 27 drives the upper cover plate 15 to rotate. The output end of the electric cylinder 12 drives the third support plate 23 to slide horizontally. The guide rods 14 on both sides of the third support plate 23 respectively slide horizontally along the upper cover plate 15. The output shaft of the sixth motor 25 drives the first connecting rod 19 to rotate. The output shaft of the fifth motor 24 drives the second connecting rod 21 to rotate. The eighth motor 29 on the second connecting rod 21 drives the whole nut installation mechanism 8 to rotate, enabling multi-directional adjustment of the position of the nut installation mechanism 8.

[0052] Among them, the nut installation mechanism 8 automatically installs nuts 30 on each second screw 10. The working principle of the nut installation mechanism 8 for automatically installing nuts 30 on each first screw 9 is as follows: Manually push the baffle 809 to slide in the fixed frame 826, the first feed port 813 opens, the open end of the second support frame 803 communicates with the first feed port 813, and a plurality of nuts 30 are stacked vertically inside the bolt storage cylinder 802 in sequence through the first feed port 813 and the open end at the bottom of the second support frame 803. Since the plane of the baffle 809 abuts against the lowermost nut 30 inside the bolt storage cylinder 802, the nuts 30 inside the bolt storage cylinder 802 will not leak out of the bolt storage cylinder 802. When automatically installing the nut 30, the output shaft of the third motor 814 drives the third gear 815 to rotate. The third gear 815 drives the rack 807 to slide horizontally in the internal slideway 827 inside the second support frame 803 through meshing transmission with the rack 807. The rack 807 pushes the lowermost nut 30 inside the bolt storage cylinder 802 into the internal slideway 827. The nut 30 inside the internal slideway 827 is pushed through the second feed port 828 into the inner cylinder 810 of the fixed cylinder 804. The nut 30 is clamped with the nut hole in the inner cylinder 810. When the nut 30 enters the nut hole in the inner cylinder 810, the second contact plate 819 abuts against the nut 30. The second contact plate 819 slides vertically inside the fixed cylinder 804 through the second slide rod 821. The output shaft of the fourth motor 823 drives the fourth gear 824 to rotate. The fourth gear 824 drives the first toothed ring 818 to rotate through meshing transmission with the first toothed ring 818. The first toothed ring 818 drives the inner cylinder 810 to rotate. By adjusting the center line of the nut 30 in the inner cylinder 810 to be the same straight line as the center line of the second screw 10 or the first screw 9, the horizontal plane at the bottom of the inclined contact plate 811 moves to abut against the bottom plate or side plate of the third protective shell 20. Each inclined contact plate 811 slides along the inclined direction inside the inclined shell 817 respectively, and the two inclined contact plates 811 open. The nut 30 in the inner cylinder 810 is installed on the first screw 9 or the second screw 10. During the rotation of the inner cylinder 810, the nut 30 in the inner cylinder 810 is driven to rotate, and the nut 30 is tightly installed on the first screw 9 or the second screw 10 through threaded connection.

[0053] Among them, the working principle of the interference rolling mechanism 7 that respectively interferes and rolls with the side of the top plate and the bottom of the top plate of the connecting horizontal support plate 2 is as follows: the output shaft of the second motor 702 drives the first gear 703 to rotate, the first gear 703 drives the second gear 704 to rotate through meshing transmission with the second gear 704, the second gear 704 drives the cam 723 to rotate. During the process, the cam 723 respectively interferes with the interference rods 724 on both sides, and each interference rod 724 drives the first slide plate 705 to slide horizontally in the first slide hole 706 at the bottom of the vehicle body 18. The two sides of each first slide plate 705 respectively drive the second slide plate 714 to slide horizontally in the third slide hole 712 of the vehicle body 18 through the third connecting rod 715. The second slide plate 714 drives the side interference wheels 707 to move to interfere with the side surface of the top plate of the connecting horizontal support plate 2. During the walking process of the vehicle body 18, the four side interference wheels 707 respectively interfere and slide with the side surface of the top plate of the connecting horizontal support plate 2.

[0054] Each second slide plate 714 respectively drives the third slide plate 717 to slide horizontally in the second slide hole 711 of the vehicle body 18 through the first support frame 709. The sliding direction of the third slide plate 717 is parallel to the sliding direction of the second slide plate 714. The sliding directions of the third slide plate 717 and the second slide plate 714 are respectively perpendicular to the sliding direction of the first slide plate 705. The third slide plate 717 drives the interference sphere 716 on the first slide rod 718 to move to interfere with the interference inclined surface 722 of the first interference plate 713. Each first slide rod 718 slides in the third slide plate 717 and the first support frame 709. The first slide rod 718 drives the fourth slide plate 719 to slide vertically on the first support frame 709. The fourth slide plate 719 drives the bottom interference wheels 710 to move to interfere with the bottom of the top plate of the connecting horizontal support plate 2. During the walking process of the vehicle body 18, the four bottom interference wheels 710 respectively interfere and slide with the bottom surface of the top plate of the connecting horizontal support plate 2, which can enable the vehicle body 18 to walk more smoothly on the connecting horizontal support plate 2.

[0055] Among them, the working principle of the traveling mechanism 6 on the vehicle body 18 traveling on the connecting horizontal support plate 2 is as follows: the output shaft of the first motor 604 drives the fourth connecting shaft 609 to rotate. One side of the fourth connecting shaft 609 drives the first connecting shaft 603 to rotate through the second conveyor belt 608. The first connecting shaft 603 drives the third connecting shaft 606 to rotate through the first conveyor belt 607. The third connecting shaft 606 drives the first rotating wheel 602 to rotate. The other side of the fourth connecting shaft 609 drives the second connecting shaft 605 to rotate through the third conveyor belt 610. The second connecting shaft 605 drives the fifth connecting shaft 612 to rotate through the fourth conveyor belt 611. The fifth connecting shaft 612 drives the second rotating wheel 615 to rotate. The first rotating wheel 602 and the second rotating wheel 615 travel on the connecting horizontal support plate 2.
