[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example 1

[0020] like Figure 1-2 As shown, this embodiment discloses a steel casing burying device in a deepwater inclined bare rock area, including a collar 1, which can slide back and forth along a steel casing 100, and two first baffles 2 are provided on one side of the collar 1, and a slide groove is provided on the collar 1, and a slide plate 11 is slidably connected in the slide groove, and the first baffle 2 is fixedly connected to the slide plate 11, so that the first baffle 2 can slide up and down along the axis direction of the collar 1, and a first side plate 3 is fixedly connected between the two first baffles 2, and the first side plate 3 is an arc plate, and a first accommodation space is formed between the first side plate 3, the two first baffles 2 and the collar 1, and a corresponding steel cage 6 is arranged in the first accommodation space. One side of the first baffle 2 is fixedly connected to a guide ring 9 through a connecting rod.

[0021] One side of each first baffle plate 2 is slidably connected to the second baffle plate 4 through a sliding guide, and the upper and lower sides of the second side plate 5 are fixedly connected to a plurality of steel bars 51. The sliding guide comprises a guide rail 31 and a sliding sleeve 41 that are slidably matched, the guide rail 31 is fixed to one side of the first baffle plate 2, and the sliding sleeve 41 is fixed to one side of the second baffle plate 4. In this way, the second baffle plate 4 can slide up and down along the first baffle plate 2. In this way, the second side plate 5 is fixedly connected between the two second baffle plates 4, and a second accommodation space is formed between the second side plate 5, the two second baffle plates 4 and the first side plate 3.

[0022] When the steel casing burying device of this embodiment is used to bury the steel casing in a deep-water inclined bare rock area, the conventional steel casing construction method is first used to sink the steel casing 100 into the rock layer 300 in the deep-water inclined bare rock area, and the collar 1 is sleeved on the outside of the steel casing 100. Then, two risers 200 are arranged on the upper surface of the inclined rock layer 300. The two risers 200 pass through the two guide rings 9 one by one, and the collar 1 rotates around the steel casing 100. When the height difference between the two risers 200 is the smallest and both risers 200 are lower than the height of the steel casing 100, the two risers 200 are fixed, and then the collar 1 is sunk into the water along the steel casing 100 until it falls on the upper surface of the rock layer 300. Concrete is injected into the first accommodation space through the vertical pipe 200, and the vertical pipe is lifted upward while injecting concrete, so that the concrete is placed in the first accommodation space, and the injected concrete forms a reinforcement block under the action of the steel cage 6, thereby reinforcing the steel casing 100, which can increase the stability of the steel casing 100 and prevent the steel casing 100 from deflecting under the action of strong water flow. The function of the second accommodation space is to collect concrete overflowing or leaking from the first accommodation space, so that auxiliary concrete reinforcement blocks are formed in the second accommodation space, thereby assisting in reinforcing the steel casing 100, further improving the stability of the steel casing 100, and ensuring that the steel casing 100 will not deflect under the action of strong water flow. Example 2

[0023] In order to further improve the stability of the steel casing 100, a plug hole 400 is provided on the outer wall of the steel casing 100, a mounting hole is provided on one side of the collar 1, and a mounting box 7 is installed in the mounting hole. The upper and lower sides of the mounting box 7 are slidably connected to the plug rod 71, and one side of the two plug rods 71 ​​is fixedly connected to the rack 72. The mounting box 7 is rotatably connected to the gear 73, and the two racks 72 are meshed with the gear 73. A spring 74 is fixedly connected between one of the plug rods 71 ​​and the inner wall of the mounting box 7. In this way, when the collar 1 falls to the bottom along the steel casing 100, the plug rod 71 and the plug hole 400 can be aligned, and the plug rod 71 is inserted into the plug hole 400 under the elastic force of the spring 74. At the same time, under the action of the gear, the other plug rod 71 is inserted into the first accommodation space. After the concrete pouring is completed, the steel casing 100 and the reinforcement block in the first accommodation space form a whole, which further improves the stability of the steel casing 100.
