DETAILED DESCRIPTION
[0025] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:
[0026] like Figure 1 to Figure 5 As shown, this embodiment provides a reinforcement structure of a water pipe culvert, which is used to support a water pipe culvert 1, and includes a first protective layer 2 fixed above the water pipe culvert 1, and the first protective layer 2 is horizontally arranged. Figure 1 The direction indicated by the middle arrow is the flow direction of water. The upstream end of the first protective layer 2 is fixedly connected to the second protective layer 3, and the second protective layer 3 is inclined to face the water. The downstream side of the first protective layer 2 is provided with a third protective layer, and the third protective layer is inclined downward. Both ends of the upstream and downstream of the third protective layer are provided with support structures, and the third protective layer is connected and fixed to the first protective layer 2 through the support structure. The first protective layer 2 and the second protective layer 3 are segmented structures; both ends of the upstream and downstream of the first protective layer 2 extend out of the water pipe culvert 1; the first protective layer 2 is used to support the top foundation of the culvert 1, and the second and third protective layers protect the upstream and downstream sides of the water pipe culvert 1, thereby improving the stability of the foundation around the water pipe culvert 1.
[0027] Specifically, the support structure includes a connecting beam 4 and a plurality of anti-collision columns 5 , the third protective layer and the first protective layer 2 are connected and fixed via the connecting beam 4 , and the plurality of anti-collision columns 5 are fixed to the lower end of the connecting beam 4 .
[0028] Specifically, the third protective layer includes a gabion 6 and a reinforcement layer 7, both ends of which are connected to the connecting beam 4. In this embodiment, the gabion 6 and the reinforcement layer 7 are arranged to be inclined downward, and the connecting beam 4 fixedly connected to the upstream side of the gabion 6 is higher than the connecting beam 4 fixedly connected to the downstream side thereof.
[0029] In this embodiment, the gabion 6 is a wire gabion, which is made in sections, and its joints are preferably welded or mechanical joints; the outer diameter of the conduit joint should be more than 100mm smaller than the inner diameter of the steel cage; when transporting and hoisting the steel cage, deformation should be prevented, collision with the hole wall and free fall should be avoided, and it should be fixed immediately after being in place. The reinforcement layer 7 is a slope cast with fine stone concrete (grade C20).
[0030] Specifically, the first protective layer 2, the second protective layer 3, the connecting beam 4 and the anti-collision column 5 are all reinforced concrete structures. In this embodiment, the anti-collision column 5 is made of cast concrete, and the cast concrete grade is C30W6F150; when excavating near the pipe box culvert 1, reliable construction measures must be taken to ensure the stability and safety of the original pipe box culvert 1 and its ancillary structures, and to do their best not to affect their normal use. In this embodiment, before the construction of the anti-collision column 5, geological re-survey and production tests should be carried out to verify the adaptability of the set construction processes and parameters such as hole making, wall solidification mud, and pile casting. At the same time, the center line of the column is measured, the drilling hole position is arranged, and the drilling construction sequence is determined. After the second protective layer 2 is cast, it needs to be backfilled with soil.
[0031] The connecting beam 4 is provided with a plurality of structural joints 10. In this embodiment, in order to prevent the first connecting beam 4 and the second connecting beam 8 from being damaged due to thermal expansion and contraction, foundation settlement, etc., a plurality of structural joints 10 are provided on the first connecting beam 4 and the second connecting beam 5.

[0036] 1. While ensuring the stability and safety of the original pipe-box culvert 1 and its accessory structures, excavation is carried out near the pipe-box culvert 1.
[0037] 2. In combination with the previous reinforcement of the pipe box culvert 1, the anti-collision column 5 is drilled, and after the anti-collision column 5 is cast, the connecting beam 4 is cast. In this process, the casting work of the first protective layer 2, the second protective layer 3 and the gabion 6 can be carried out simultaneously, and then the casting construction of the reinforcement 7 is carried out on the gabion 6, and the gaps between the structures are filled by grouting.
