Embodiment 1
[0029] Such as Figure 1 to Figure 4 As shown, a concrete anti-scouring guide wall structure includes a construction platform 1, and the side of the construction platform 1 far away from the river is poured with an occlusal pile continuous wall 4, and a backfill pit is excavated behind the occlusal pile continuous wall 4, and the backfill pit is filled with There is a plain concrete layer 7, and the upper side of the plain concrete layer 7 close to the occlusal pile diaphragm wall 4 is poured with an upper guide wall structure concrete layer 8, and the part of the guide wall structure concrete 8 above the plain concrete layer 7 to the slope surface is paved with an access road 9 . The side of the construction platform 1 away from the river channel is drilled to the bottom of the bedrock roof line 6 by means of percussion drilling or other methods, and then the continuous wall 4 of occlusal piles is poured into it as a separation wall. The bottom layer of the backfill pit behin...
Embodiment 2
[0036] Such as Figure 1 to Figure 4 As shown, a construction method of a concrete anti-scouring guide wall structure includes the following steps. In the first step, the construction platform 1 is leveled, and the slope on the side of the river is first filled or excavated to be the construction platform 1; Fill or excavate the slope to form a construction platform 1 with an upper plane width of 5-8m, so that subsequent mechanical equipment can work on the construction platform 1.
[0037] In the second step, the occlusal pile diaphragm wall 4 is constructed, and the occlusal pile hole is constructed on the side of the construction platform 1 far away from the river, and the first-order concrete plain pile 2 is poured into the occlusal pile hole, and then the second-order reinforced concrete pile 3 is constructed, and the first-order concrete pile is constructed. The plain pile 2 and the second sequence reinforced concrete pile 3 form a closed continuous wall 4 of occlusal pi...
