[0032] Reference Figure 1 An embodiment of the utility model shows a water-side roadbed slope support structure, including steel pipe support retaining wall 1, first cast-in-place concrete strip foundation 2, second cast-in-place concrete strip foundation 3 and transverse connecting component 4;Steel pipe support retaining wall 1 includes a plurality of steel pipe piles 11 arranged, steel pipe support retaining wall 1 is arranged at the first side (the first side is water side) of roadbed;First cast-in-place concrete strip foundation 2 is arranged at the top of steel pipe support retaining wall 1, and at least part of first cast-in-place concrete strip foundation 2 is lower than the top surface of roadbed;Second cast-in-place concrete strip foundation 3 is arranged inside the second side of roadbed;Transverse connecting component 4 is provided with a plurality of transverse connecting components 4, and a plurality of transverse connecting components 4 are distributed along the longitudinal direction of roadbed, and the transverse connecting component 4 is arranged inside the roadbed and at least 1m away from the top surface of roadbed, and one end of the transverse connecting component 4 is connected with the first cast-in-place concrete strip foundation 2, and the other end is connected with the second cast-in-place concrete strip foundation 3.

[0033] As shown in Figure 2 The steel pipe pile 11 includes a pipe pile body 111, one side of the pipe pile body 111 is provided with a T-shaped connecting part 112, and the other side is provided with a C-shaped connecting part 113;The T-shaped connecting part 112 on one steel pipe pile 11 is clamped with the C-shaped connecting part 113 on another steel pipe pile 11. Specifically, the T-shaped connecting part 112 is formed by an I-beam welded on one side of the pipe pile body 111, and the C-shaped connecting part 113 is formed by a small steel pipe welded on the other side of the pipe pile body 111, and one side of the small steel pipe is provided with a gap 114 for clamping the T-shaped connecting part 112. Figure 3As shown, when two adjacent steel pipe piles 11 are connected, the web of the T-shaped connecting part 112 (I-shaped steel) is clamped into the gap 114, the flange plate of the T-shaped connecting part 112 (I-shaped steel) is located inside the C-shaped connecting part 113, and the flange plate of the T-shaped connecting part 112 (I-shaped steel) cannot pass through the gap 114, thereby achieving the connection between the two steel pipe piles 11. In this way, a plurality of steel pipe piles 11 are connected in sequence to form the steel pipe retaining wall 1.

[0034] The steel pipe retaining wall 1 refers to the cofferdam structure of bridge construction, and the technology of bridge construction is innovatively applied to slope support in the embodiment. The steel pipe retaining wall 1 adopts the mature steel pipe pile 11, which can be inserted and driven by mature equipment such as a truck crane combined with a vibration pile hammer. The construction technology is mature and efficient, can quickly form a water retaining barrier to prevent further damage to the roadbed, and has the advantages of less construction interference, no interruption of existing traffic, high construction efficiency, short construction time, and guarantee of traffic safety and road structure safety during emergency disposal engineering construction process and use period.

[0035] In addition, the roadbed will generate lateral earth pressure on the steel pipe retaining wall 1. In the embodiment, as shown in Figure 1 The second cast-in-place concrete strip foundation 3 is used as an anchoring structure, and the transverse connecting member 4 is used to pull the first cast-in-place concrete strip foundation 2 and the second cast-in-place concrete strip foundation 3 to form an anchoring structure system, which can balance the lateral earth pressure on the steel pipe retaining wall 1, so that the overall support structure has good stability and high safety factor. At the same time, when pouring and constructing the first cast-in-place concrete strip foundation 2 and the second cast-in-place concrete strip foundation 3, only the roadbed edge position on both sides needs to be operated and constructed, and the center of the roadbed can still be open to traffic, which can reduce the influence on road traffic.

[0036] The longitudinal direction of the roadbed refers to the length direction of the road, and the transverse direction of the roadbed refers to the width direction of the road.

[0037] Specifically, in the above scheme, the transverse connecting member 4 is a tie bar. One end of the tie bar is welded to the steel pipe retaining wall 1, and the other end is welded to the reinforcing steel in the second cast-in-place concrete strip foundation 3. The tie bar is an HRB400 steel bar with a diameter of 32mm. During construction, a trench is excavated on the second side of the roadbed to accommodate the second cast-in-place concrete strip foundation 3. A reinforcing cage for forming the second cast-in-place concrete strip foundation 3 is arranged in the trench. Holes with a diameter of 50mm are drilled every 2m along the longitudinal direction of the roadbed at a position at least 1m away from the top surface of the roadbed. The holes are located away from the top surface of the roadbed so as not to affect vehicle traffic. The transverse connecting member 4 is passed through these holes, with one end welded to the reinforcing cage in the trench and the other end welded to the steel pipe retaining wall 1. Then, the second cast-in-place concrete strip foundation 3 is formed by pouring concrete. In this embodiment, the cross-section of the second cast-in-place concrete strip foundation 3 is a 1m × 1m square, and the length direction of the second cast-in-place concrete strip foundation 3 is arranged along the longitudinal direction of the roadbed.

[0038] Specifically, in the above scheme, after connecting the transverse connecting member 4 to the steel pipe retaining wall 1, a reinforcing cage is welded and a formwork is installed on the top of the steel pipe retaining wall 1, and then the first cast-in-place concrete strip foundation 2 is formed by pouring concrete. The first cast-in-place concrete strip foundation 2 covers the connection between the transverse connecting member 4 and the steel pipe retaining wall 1, ensuring a stable connection between the transverse connecting member 4 and the steel pipe retaining wall 1. Furthermore, the cross-sectional height of the first cast-in-place concrete strip foundation 2 extends from 60cm below the top of the steel pipe retaining wall 1 to be flush with the top surface of the roadbed. In other words, as... Figure 1 As shown, the first cast-in-place concrete strip foundation 2 at least covers the top L2 of the steel pipe retaining wall 1, with L2 being at least 60cm, ensuring that the first cast-in-place concrete strip foundation 2 and the steel pipe retaining wall 1 are stable and do not separate. In the initial state, the top of the first cast-in-place concrete strip foundation 2 is flush with the top surface of the roadbed. The top of the first cast-in-place concrete strip foundation 2 is used as the elevation, which can be used to compare with the height of the top surface of the roadbed to determine whether the roadbed is sunken or whether the steel pipe retaining wall 1 has a tendency to tilt and collapse.

[0039] Specifically, to avoid affecting the roadbed during the construction of the steel pipe retaining wall 1, the above scheme includes, for example... Figure 1 As shown, the distance L1 between the steel pipe retaining wall 1 and the first side edge of the roadbed is at least 60cm. This ensures that when using a truck crane with a vibratory pile hammer and other mature equipment to drive the steel pipe piles 11, excessive vibration to the roadbed can be avoided. Furthermore, to ensure the stable installation of the steel pipe retaining wall 1, such as... Figure 1 As shown, the steel pipe retaining wall 1 is inserted into the riverbed at least 5m.

[0040] In the above embodiments, the description of each embodiment has its own focus, and the parts not described in detail in a certain embodiment can be referred to the relevant description of other embodiments.

[0041] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
