The positioning holes 51 are respectively formed in the end faces of two opposite sides of the positioning plate 5, and the cross sections of the positioning holes 51 are semicircular and extend in the vertical direction. When two adjacent positioning plates 5 are spliced, a through hole 52 is formed between the adjacent positioning holes 51 on the two positioning plates 5 in a surrounding manner, and the aperture of the through hole 52 is slightly larger than the diameter of the fixing pile 3. When the positioning plate 5 is assembled, the positioning plate 5 extends into the space between two adjacent fixing piles 3 from top to bottom, so that the fixing piles 3 penetrate into the positioning holes 51 close to the fixing piles; after the assembly is in place, spud pile 3 can be laminated with the pore wall of through-hole 52 to hinder locating plate 5 from moving horizontally relative to spud pile 3, easy dismounting.
Referring to fig. 2 and 3, two sets of limiting members are disposed on the upper side of each fixing pile 3 for stopping the positioning plate 5 close to the fixing pile 3 from moving upward. The locating part includes rotates the stopper 6 of connection on the spud pile 3 through pivot 63 level, and pivot 63 is close to the edge of spud pile 3 to pivot 63 among two sets of locating parts is circumference equipartition along the axis of spud pile 3. After the positioning plate 5 is inserted in place, the limiting block 6 is rotated to one side close to the positioning plate 5 until the limiting block 6 abuts against the positioning plate 5, the limiting block 6 can block the positioning plate 5 to move upwards, and the stability of the positioning plate 5 is improved. In order to prevent the limiting block 6 from continuing to rotate after moving to the position above the positioning plate 5, the limiting bolt 61 in threaded connection with the positioning plate 5 can be arranged on the limiting block 6 in a penetrating mode, and therefore stability of the limiting block 6 is improved.
Referring to fig. 3 and 4, a hemispherical fixture block 62 is fixed to the lower end surface of the limiting block 6, and the fixture block 62 is made of plastic capable of generating elastic deformation, such as PE. Two hemispherical draw-in grooves 31 have been seted up to the up end of spud pile 3, and two draw-in grooves 31 are circumference equipartition along the axis of spud pile 3, and draw-in groove 31 and rather than close pivot 63 interval equal fixture block 62 and rather than close pivot interval, fixture block 62 and draw-in groove 31 joint cooperation. When the clamping block 62 is clamped into the clamping groove 31 close to the clamping block, the end part of the limiting block 6 does not exceed the fixing pile 3, and the disassembly and assembly of the positioning plate 5 cannot be influenced.
Referring to fig. 5, in order to reduce the length of the single positioning plate 5 in the vertical direction and reduce the difficulty in mounting the positioning plate 5, the positioning plate 5 in this embodiment includes two base plates 53 having the same structure. The upper end face of each base plate 53 is integrally formed with a water blocking block 531, the lower end face of each base plate 53 is provided with a water blocking groove 532 matched with the water blocking block 531, and the water blocking block 531 of one base plate 53 is embedded in the water blocking groove 532 positioned right above the base plate, so that river water is not easy to flow to the revetment 1 from the gap between the two base plates 53.
Referring to fig. 2, a positioning gap 54 is formed between two adjacent positioning plates 5, a baffle plate 55 is arranged on one side of the positioning gap 54 away from the revetment 1, the length of the baffle plate 55 is equal to that of the positioning gap 54, and the width of the baffle plate 55 is greater than that of the positioning gap 54. Both ends of the baffle plate 55 in the width direction thereof are detachably connected to the positioning plate 5 adjacent thereto through fasteners 56, specifically, the fasteners 56 in this embodiment are fastening bolts inserted into the baffle plate 55 and screwed to the positioning plate 5.
Referring to fig. 2, a connecting rod 21 is fixed between any two adjacent reinforcing piles 2, and the connecting rod 21 is arranged at the top end of each reinforcing pile 2 to enhance the integrity of the reinforcing pile 2 and the strength of the reinforcing pile 2.
