The collar 1 is rotatably connected to two opposite side walls away from the pile foundation with rotating rods 2, and each rotating rod 2 is provided with a plurality of ground nails 3 on the lower side of the end away from the side wall of the connected collar 1, and each rotating rod 2 is connected to the adjacent ground nails 3 with a linkage assembly 4, and the linkage assembly 4 can drive the ground nails 3 to move downward during the rotation of the rotating rod 2.

[0033] During actual use, the collar 1 is first sleeved on the outside of the pile foundation, and then the collar 1 is moved downward. During the downward movement, the collar 1 drives the two connected rotating rods 2 to rotate. During the rotation, the two rotating rods 2 drive the ground nails 3 to move downward through the linkage assembly 4, thereby realizing the process of reinforcing the pile foundation through the connection between the ground nails 3 and the rotating rods 2.

[0034] The collar 1 is moved along the pile foundation to drive the ground nails 3 to be inserted into the foundation, thereby facilitating the workers to reinforce and protect the pile foundation through the collar 1 and the connected ground nails 3 .

[0035] The linkage assembly 4 includes a linkage box 41 located at the lower side of the pile foundation, each rotating rod 2 is inserted into the linkage box 41 and is rotatably and slidably connected with a lifting plate 42, and each rotating rod 2 is rotatably connected to the top side wall of the linkage box 41 through a rotating shaft and a connecting rod near the middle. The side wall of each lifting plate 42 is slidably abutted against the inner wall of the linkage box 41 in the vertical direction. Each lifting plate 42 is penetrated and threadedly connected with a linkage screw 43, and each linkage screw 43 is vertically arranged and the end is rotatably connected to the inner wall of the adjacent linkage box 41.

[0037] In the process of the ring member 1 moving downward, the connected rotating rod 2 is driven to rotate, and each rotating rod 2 drives the connected lifting plate 42 to move upward in the process of rotation. In the process of the lifting plate 42 moving upward, the connected linkage screw 43 is driven to rotate, and the linkage screw 43 drives the connected linkage driving gear 44 to rotate in the process of rotation.

Each linkage slave gear 45 drives the connected ground nail 3 to move downward in the process of rotation, thereby realizing the process of driving the ground nail 3 to be inserted into the foundation in the process of the movement of the ring member 1.

[0038] Reference Figure 3The collar member 1 includes a first collar 11 and a second collar 12 which are arranged opposite to each other. The first collar 11 and the second collar 12 are both arranged in a C-shape and are arranged opposite to each other. A plug-in block 111 is fixedly connected to the end of each first collar 11, and a plug-in slot 121 for the plug-in block 111 to be plugged into is provided at the end of each second collar 12. The first collar 11 is connected to a locking member 5, which is used to connect the first collar 11 and the second collar 12. The opposite sides of the first collar 11 and the second collar 12 are both rotatably connected to one of the rotating rods 2.

[0039] When it is necessary to sleeve the first ring 11 and the second ring 12 onto the outside of the pile foundation, the ends of the first ring 11 and the second ring 12 are connected and the pile foundation is located between the first ring 11 and the second ring 12, and then the first ring 11 and the second ring 12 are connected by the locking member 5, thereby realizing the process of sleeved the first ring 11 and the second ring 12 onto the outside of the pile foundation.

[0040] The locking member 5 includes two locking rods 51 slidably plugged into each plug-in block 111. The two locking rods 51 are arranged opposite to each other and a pressure spring 52 is fixedly connected between the ends of the two locking rods 51 located inside the plug-in block 111. Two locking holes 122 are arranged opposite to each other and are provided inside each locking groove for plugging the two locking rods 51 connected to the same plug-in block 111.

[0041] When the plug-in rod is inserted into the plug-in slot 121 , the locking rod 51 connected to the plug-in rod is inserted into the adjacent locking hole 122 driven by the pressure spring 52 , thereby limiting the position between the first ring 11 and the second ring 12 .

[0042] The upper and lower parts of each C-shaped short side wall of the first collar 11 and the second collar 12 are connected with a plurality of fixing rods 6, and the fixing rods 6 connected to the same side wall are arranged at intervals. Each fixing rod 6 can abut against the connected first collar 11 or second collar 12 and the adjacent pile foundation side wall at the same time. The first collar 11 and the second collar 12 are internally connected with a driving assembly 7, and the driving assembly 7 is used to drive the fixing rod 6 connected to the first collar 11 or the second collar 12 to abut against the adjacent pile foundation side wall.

[0043] By providing a fixing rod 6 and driving the fixing rod 6 to move through the driving assembly 7, the fixing rod 6 can further limit the position between the first ring 11 and the second ring 12 and the pile foundation, making the connection relationship between the first ring 11 and the second ring 12 and the pile foundation more stable.

[0044] The driving assembly 7 includes a driving rod 71 inserted into the side wall of the first collar 11 or the second collar 12 connected to the fixing rod 6. Each driving rod 71 is fixedly connected to a trapezoidal stopper 72 on one side close to the adjacent fixing rod 6. The inclined side wall of each trapezoidal stopper 72 and the side wall arranged parallel to the connected driving rod 71 can abut against the adjacent fixing rod 6 and drive the fixing rod 6 to move to the side away from the driving rod 71. Each fixing rod 6 is arranged to be inclined from the side close to the adjacent driving rod 71 to the side away from the adjacent driving rod 71 and gradually to the side close to the adjacent pile foundation side wall.

[0045] One end of each driving rod 71 connected to the first ring 11 is slidably inserted into the inside of the plug-in block 111 and the end is set to be conical. The conical side wall of each driving rod 71 is abutted against multiple driving blocks 73. In the present embodiment, two driving blocks 73 are arranged opposite to each other up and down and the opposite sides of the two driving blocks 73 are connected to the driving connecting rod. The end of each driving block 73 away from the abutted driving rod 71 passes through the side wall of the adjacent plug-in block 111 in the vertical direction and slides and abuts against the side wall of the plug-in block 111 in the vertical direction.

[0046] One end of each driving rod 71 connected to the inside of the second ring 12 is slidably inserted into the inside of the insertion groove 121 .

[0047] In the process of connecting the first ring 11 and the second ring 12, the plug-in rod is inserted into the opposite plug-in groove 121. In the process of inserting the plug-in rod into the plug-in groove 121, the two driving blocks 73 abut against the groove wall of the plug-in groove 121. Then, the driving block 73 is pushed into the plug-in block 111 under the squeezing of the plug-in groove 121, so that the driving block 73 drives the driving rod 71 to move into the connected first sleeve. In the process of movement, the driving rod 71 drives the connected trapezoidal abutment block 72 to abut against the fixing rod 6, thereby driving the fixing rod 6 to move out of the first ring 11 and abut against the adjacent pile foundation side wall.

[0048] When the plug-in block 111 is plugged into the plug-in slot 121, the plug-in block 111 drives the driving rod 71 inside the plug-in slot 121 to move toward the connected second ring 12, and the second ring 12 drives the connected trapezoidal abutment block 72 to move. During the movement of the trapezoidal abutment block 72, it drives the adjacent fixing rod 6 to move out of the second ring 12 and abut against the adjacent pile foundation side wall, thereby realizing the process of further strengthening the connection between the first ring 11 and the second ring 12 and the pile foundation through the fixing rod 6.

[0049] Reference Figure 2A supporting screw 8 is provided on the lower side of each rotating rod 2, and each supporting screw 8 is connected to a water drive component 9. The water drive component 9 is used to drive the lower end of the supporting screw 8 to be inserted into the abutment and the upper end to abut against the side wall of the pile foundation, thereby further fixing the pile foundation.

[0050] The upper end of each supporting screw 8 is rotatably connected with a slider 81, and the rotation range of each supporting screw 8 and the connected slider 81 is limited in the same vertical plane. One end of each slider 81 away from the connected supporting screw 8 is slidably connected to the pile foundation side wall along the vertical direction.

[0051] The outside of each supporting screw 8 is threadedly sleeved with a supporting sleeve 82. The water drive assembly 9 includes a water drive box 91 located at the lower side of each supporting sleeve 82. The outer wall of each supporting sleeve 82 is rotatably connected to the outer top wall of the adjacent water drive box 91.

[0052] One side wall of each water drive box 91 is in contact with the adjacent pile foundation side wall, and each water drive box 91 is provided with a plurality of leaking holes 911 penetrating the side wall of the water drive box 91 on the side away from the pile foundation side wall, and the side wall of the water drive box 91 provided with the leaking holes 911 and the top side wall of the water drive box 91 are also provided with an opening for the support sleeve 82 to rotate out of the water drive box 91. Each water drive box 91 is provided with a sinking and floating plate 92 inside, each sinking and floating plate 92 is made of foam or other materials, and each sinking and floating plate 92 is provided with a plurality of through holes in the vertical direction. Each sinking and floating plate 92 can be in contact with the outer wall of the support sleeve 82 during the upward movement and drive the lower end of the support sleeve 82 to move out of the water drive box 91 from the opening provided by the water drive box 91.

[0053] Each water drive box 91 is provided with a vertically arranged water drive screw 93, each water drive screw 93 penetrates the sinking and floating plate 92 and is threadedly connected to the sinking and floating plate 92, and the upper and lower ends of each water drive screw 93 are rotatably connected to the inner wall of the adjacent water drive box 91. The upper end of each water drive screw 93 is wound with a connecting rope 94, and the upper end of each connecting rope 94 penetrates the top wall of the connected water drive box 91 and is wound with a winding sleeve 95, and each winding sleeve 95 is threadedly sleeved to the outside of the adjacent water drive screw 93 and is rotatably connected to the adjacent support sleeve 82.

[0054] When the external water level is too high, the external water enters the water drive box 91 through the leaking hole 911, and then drives the sinking and floating plate 92 to move upward. In the process of moving upward, the sinking and floating plate 92 drives the bottom of the supporting sleeve 82 to rotate out of the water drive box 91, and the sinking and floating plate 92 drives the water drive screw 93 to rotate in the process of moving upward. The water drive screw 93 drives the connecting rope 94 to tighten in the process of rotation. The connecting rope 94 drives the winding sleeve 95 to rotate in the process of tightening. The winding sleeve 95 drives the lower end of the supporting screw 8 to pass through the supporting sleeve 82 and connect with the adjacent foundation in the process of rotation, thereby realizing the connection between the adjacent foundation and the pile foundation side wall by the external water flow, thereby realizing the reinforcement operation of the pile foundation side wall.

[0055] The implementation principle of a reinforcement and protection device for a bridge pile foundation in an embodiment of the present application is as follows: in actual use, the first ring 11 and the second ring 12 are connected so that a plurality of fixing rods 6 limit the positions of the first ring 11 and the second ring 12, and then move in the vertical direction to drive a plurality of ground nails 3 to be inserted into the foundation to achieve preliminary fixation of the pile foundation.

[0056] When the water level rises, the water flow drives the sinking and floating plate 92 to move upward, and the sinking and floating plate 92 drives the connected supporting screw 8 to be inserted into the foundation and abut against the side wall of the pile foundation, thereby realizing a further reinforcement process of the pile foundation.
