Embodiment 1
[0065] Embodiment 1: a revetment reinforcement facility and its construction method, such as figure 1 As shown, including the revetment 2, a mortar block stone 22 is arranged on the side of the revetment 2 facing the river channel 1, the mortar block stone 22 is arranged along the surface of the revetment 2, and a concrete topping 23 is arranged on the top of the mortar block stone 22, The top of the concrete top 23 is flush with the upper surface of the revetment 2 . In front of the revetment 2, there are several bored piles 4 arranged along the length direction of the river bed 3. The bored piles 4 are arranged in the vertical direction. The height of the bored piles 4 is between 12-22m and higher than the river bed. The surface of 3 is 2.8m, and the diameter of bored pile 4 is 0.8m.
[0066] Reinforcing piles 5 corresponding to the bored piles 4 are arranged in front of the revetment 2. The reinforcement piles 5 are located between the revetment 2 and the bored piles 4. Th...
Embodiment 2
[0072] Embodiment 2: as Figure 7 and Figure 8 As shown, the difference from Embodiment 1 is that the sheet pile 7 is arranged between two adjacent bored piles 4, and the length of the sheet pile 7 is smaller than the interval between adjacent piles.
[0073] Between the sheet pile 7 and the bored pile 4, there is an inserting plate 21 that sinks into the river bed 3. The two ends of the inserting plate 21 abut against the bored pile 4 and the sheet pile 7 respectively, and the top of the inserting plate 21 is in contact with the plate. The piles 7 are flush, and inserting plates 21 of different lengths are cut according to the distance between the bored pile 4 and the sheet pile 7 .
[0074] Such as Figure 9 As shown, a concrete filling layer 25 is coated between the inserting plate 21 and the bored pile 4 to reduce the gap between the inserting plate 21 and the bored pile 4 . And a waterproof layer is applied to the abutment between the inserting plate 21 and the bored ...
Embodiment 3
[0075] Embodiment 3: A kind of construction method of revetment reinforcement facility, adopts revetment reinforcement facility as described in embodiment 1 or 2, and its construction method is as follows:
[0076] S1, survey the river channel 1 and the revetment 2, detect the damaged area, give priority to reinforcement of the damaged revetment 2, slow down the damage of the revetment 2, ensure the safety of residents, and mark the area to be reinforced;
[0077] S2, build a cofferdam in the area to be reinforced, and then drain the river water in the cofferdam, so that the staff can perform reinforcement work on the river bed 3, which is convenient for the staff to operate;
[0078] S3-1, because the original surface of the river bed 3 is uneven, which will affect the accuracy of the drilling rig when drilling, use the bulldozer to level the upper end surface of the river bed 3;
[0079] S3-2. Since the soil on the upper surface of the river bed 3 is relatively soft, a first...
