[0002] With the rapid development of my country's economy, the road network is becoming increasingly dense, and correspondingly, there are more and more high-embankment highways along rivers. To avoid encroaching on river channels, retaining walls are usually used to construct the roadbed structure. However, retaining wall structures with high embankments require deep excavation of the retaining wall foundation, which can pose safety hazards to river embankments, increasing the risk of leakage or dam failure. Therefore, this utility model proposes a pile-slab retaining wall structure for plains along rivers, which eliminates the need for foundation excavation, avoids safety hazards to river embankments, allows for rapid construction, and provides a high safety factor for both river flood control and traffic.

[0004] This utility model discloses a pile-slab retaining wall structure along a river in a plain, comprising, from bottom to top, pile foundations, a square foundation, T-shaped columns, and retaining plates arranged on the outer side of the river channel. The pile foundations are evenly spaced along the river channel and are located below ground level. The square foundation is cast on the upper end of the pile foundations, and the lower end of the T-shaped columns is fixed to the square foundation. The feature is that retaining plates are fixed from top to bottom on the side of adjacent T-shaped columns facing the roadbed. Two installation openings are provided on the side of the T-shaped columns facing the roadbed, and the ends of the retaining plates are placed in the installation openings. Anchor steel bars that are fixedly connected to the retaining plates are pre-embedded at the installation openings of the T-shaped columns.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] like Figure 1 The diagram shows a structural schematic of the pile-slab retaining wall structure for riverbanks along plains according to this utility model. Figure 2A schematic diagram of the retaining plate fixing structure on the T-shaped column in this utility model is provided. The plain riverside pile-plate retaining wall structure of this utility model consists of pile foundations 1, square pile caps 2, T-shaped columns 3, and retaining plates. The pile foundations 1 are evenly spaced along one side of the river channel, and the pile foundations 1, square pile caps 2, T-shaped columns 3, and retaining plates are arranged sequentially from bottom to top. The pile foundations 1 are located below the ground on one side of the river channel 8, and the pile foundations 1 located below the ground provide support for the superstructure. The square pile caps 2 are fixed to the upper end of the pile foundations 1, and the T-shaped columns 3 are fixed to the square pile caps 2. In this way, the pile foundations 1, square pile caps 2, and T-shaped columns 3 form a stable support structure for the retaining plate.
[0018] The retaining plate is fixed to the side of the T-shaped post 3 facing the roadbed 6. Adjacent T-shaped posts 3 are connected by the retaining plate, that is, the two ends of the retaining plate are fixed to the two adjacent T-shaped posts 3. The cross-section of the T-shaped post 3 is T-shaped, that is, two installation openings 9 are provided on the side of the T-shaped post 3 facing the roadbed 6. The two ends of the retaining plate are located in the installation openings 9. Anchor steel bars 7 are pre-embedded on the pile foundation 1 at the installation openings 9. The anchor steel bars 7 are connected to the ends of the retaining plate to fix the retaining plate on the T-shaped post 3.
[0019] The retaining wall shown consists of an upper retaining wall 4 and a lower retaining wall 5. The retaining wall 4 is located above the middle part of the T-shaped column 3, and the retaining wall 5 is located below the middle part of the T-shaped column 3. During construction, the lower retaining wall 5 is installed first, followed by the backfilling of the roadbed. After the roadbed is flush with the lower retaining wall 5, the adjacent upper retaining wall 4 is installed, and the installation gap between two adjacent retaining walls is no more than 1 cm.
[0020] As can be seen, the plain riverbank pile-slab retaining wall structure of this utility model, because it uses pile foundation 1 to support the square pile cap 2, T-shaped column 3 and retaining plates (i.e., upper retaining plate 4 and lower retaining plate 5) above, will not cause damage to the embankment on one side of the river channel 8 during the construction of pile foundation 1, and will not pose a safety hazard to the base plate. By fixing the retaining plate to the side of the T-shaped column 3 facing the roadbed 6, the roadbed 6 is blocked and supported, ensuring the stability of the formed roadbed 6.
[0021] Among them, pile foundation 1 can be a bored cast-in-place pile, with a diameter of 1.2m to 1.5m and using concrete with a strength of 30MPa to 40MPa. The square pile cap 2 is a reinforced concrete structure with a square cross-section, a side length of 1.4m to 1.9m, a height of 0.6m to 1.2m, and using concrete with a strength of 30MPa to 40MPa.
[0022] The T-shaped column 3 is a reinforced concrete structure with a T-shaped cross-section, and uses concrete with a strength of 40MPa to 45MPa. The upper retaining plate 4 and lower retaining plate 5 are 0.5m wide, 4.0m to 6.0m long, and 0.2m to 0.25m thick, and also use 40MPa to 45MPa concrete. The retaining plates are welded to the anchoring steel bars 7 on the T-shaped column 3 using welded steel bars, which are coated with anti-rust paint. The installation gap between adjacent upper and lower retaining plates is no greater than 1cm.
