[0026] Please refer to Figure 1 、 Figure 2 、 Figure 3The pipe pile body 1 is internally equipped with a reinforcing mechanism 14, which includes a clearance groove 140. The clearance groove 140 is formed on the surface of the pipe pile body 1. A support frame 141 is fixedly connected to the inner wall of the pipe pile body 1. A positive and negative threaded screw 142 is installed on the vertical part of the support frame 141 through a bearing. Two evenly distributed screw cylinders 143 are threadedly connected to the outer side of the positive and negative threaded screw 142. A movable plate 144 is fixedly connected to the end face of each screw cylinder 143. The movable plate 144 is slidably connected to the clearance groove 140. The end face of the movable plate 144 is fixedly connected to... There is an extrusion plate 145, which is slidably connected to the clearance groove 140. A bevel gear 146 is fixedly sleeved on the outer side of the positive and negative threaded screw 142. A fixing plate 147 is fixedly connected to the inner wall of the pipe pile body 1. A motor 148 is fixedly installed on the upper end of the fixing plate 147. The output shaft of the motor 148 is rotatably connected to the fixing plate 147. Through the arrangement of the motor 148, bevel gear 146 and other structures, the positive and negative threaded screw 142 can be driven to rotate, so as to drive the moving plate 144 and the extrusion plate 145 to penetrate into the soil and reinforce the pipe pile body 1.

[0027] Please see Figure 1 , Figure 2 , Figure 3 There are two clearance grooves 140, which are symmetrically distributed on the pipe pile body 1. The clearance grooves 140 ensure the normal movement of the moving plate 144 and the pressing plate 145. A bevel gear 149 is fixedly sleeved on the outside of the output shaft of the motor 148.

[0028] The specific implementation process of this utility model is as follows: In use, by pushing the washer 5 to contact the connecting ring 3, and then pushing the support ring 7 to contact the washer 5, the through hole 1 6, the through hole 2 8, and the threaded hole 4 are aligned, and the reinforcing ring 11 passes through the washer 5 and is inserted into the pipe pile body 1. Under the action of the reinforcing rib 12, the stability of the pile cap 13 can be ensured. Then, the bolt 10 is pushed through the washer 9, and the bolt 10 passes through the through hole 2 8 and the through hole 1 6 in sequence, and finally the bolt 10 contacts the threaded hole 4. The bolt 10 is rotated to make the bolt 10 make threaded movement, and the bolt 10 is installed. Then the support ring 7 is locked. With the action of the pile cap 13, the pipe pile body 1 can be hammered, so that the pipe pile body 1 is inserted into the ground for use.

[0029] After the pipe pile body 1 is inserted into the ground, the motor 148 is started to drive the output shaft to rotate, thereby driving the bevel gear 149 to rotate. Under the meshing relationship, the bevel gear 149 drives the bevel gear 146 to rotate, thereby driving the positive and negative threaded screws 142 to rotate. Under the threaded connection, since the threads of the positive and negative threaded screws 142 are symmetrically distributed and the threads are opposite in direction, the two screw cylinders 143 can be driven to move away from each other, thereby driving the moving plate 144 to move along the inner wall of the clearance groove 140, and finally driving the pressing plate 145 to move, so that the pressing plate 145 and the moving plate 144 penetrate deeper into the ground, thereby improving the insertion stability of the pipe pile body 1 and ensuring the good horizontal load effect of the pipe pile body 1.
