[0020] 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

[0021] like Figure 1-4 As shown, this embodiment discloses a steel casing sinking construction device in a complex stratum deep water area, including a rectangular ring 1 and two traveling vehicles 2, wherein a group of support columns 11 are fixedly connected to the lower side of the rectangular ring 1. Two tracks 12 are fixedly connected to the upper side of the rectangular ring 1, and the wheels 21 of the traveling vehicles 2 travel on the tracks 12 in a one-to-one correspondence. A connecting plate 22 is fixed on one side of each traveling vehicle 2, and a guide ring 23 is fixedly connected between the two connecting plates 22. The steel casing 200 passes through the guide ring 23, and a plurality of guide wheels are installed on the inner wall of the guide ring 23, and the guide wheels are in contact with the outer wall of the steel casing 200. The guide ring 23 and the guide wheels can assist in guiding the steel casing 200 to prevent the steel casing 200 from deflecting during the sinking process.

[0022] At the same time, in order to improve the stability of the steel casing 200, the present embodiment reinforces the steel casing 200, specifically, a reinforcement ring 5 is fixedly connected to the lower end of the steel casing 200, and a first reinforcement device 7 and a second reinforcement device 8 are fixedly connected to the reinforcement ring 5. The steel casing 200 is reinforced by the first reinforcement device 7 and the second reinforcement device 8 to prevent the steel casing 200 from tilting due to the impact force of water flows in different directions.

[0023] The first reinforcement device 7 includes a cross beam, which is fixed on the reinforcement ring 5, and a tapered rod is installed on the cross beam. When the bottom of the steel casing 200 is inserted into the rock or soil, the tapered rod is also inserted into the rock or soil, forming a reinforcement point at the tapered rod, so that when encountering water flow impact, the tapered rod can provide a certain reinforcement force for the steel casing 200.

[0024] In order to further improve the reinforcement force of the steel casing 200, the second reinforcement device 8 includes a reinforcement box 81, which is fixed to the reinforcement ring 5 through the diagonal support rod 51. The top of the reinforcement box 81 is provided with a central threaded hole, and the central threaded hole is threadedly connected to the rotating shaft 82, and the lower end of the rotating shaft 82 is fixedly connected to the conical drill 83. When the bottom of the steel casing 200 is inserted into the rock or soil, the rotating shaft 82 rotates to make the conical drill 83 rotate downward, and the conical drill 83 is inserted into the rock or soil, which can effectively avoid the situation that the steel casing 200 is unstable due to uneven rocks or soil. The steel casing 200 is reinforced by the conical drill 83 and the conical rod, which can effectively improve the stability of the steel casing 200.

[0025] At the same time, in order to further improve the reinforcement force of the steel casing 200, a sleeve 86 arranged obliquely is fixedly connected to the lower part of one side of the reinforcement box 81, and a rib 87 is slidably connected in the sleeve 86. A vertical guide groove 89 is arranged on the inner wall of the reinforcement box 81, and a wedge block 88 is slidably connected in the guide groove 89. An annular groove 811 is arranged on the rotating shaft 82, and an insertion rod 810 is fixedly connected to one side of the wedge block 88. The insertion rod 810 is inserted into the annular groove 811 and can slide along the annular groove 811. In this way, when the rotating shaft 82 rotates and moves downward, the position of the annular groove 811 also decreases as the rotating shaft 82 decreases, so that the wedge block 88 will also slide downward along the guide groove 89, so that the rib 87 moves obliquely downward, and the rib 87 is obliquely inserted into the rock or soil, so that the conical drill 83 is reinforced by the rib 87, the strength of the conical drill 83 is enhanced, and the reinforcement force of the steel casing 200 is indirectly improved.

[0026] In order to facilitate the rotation of the rotating shaft 82, the upper end of the rotating shaft 82 is fixedly connected to the end head 85, and the end head 85 is threadedly connected to the driving rod 9 through the stud 92. The upper end of the driving rod 9 is rotatably connected in the avoidance hole of the connecting plate 22, and the driver 3 is fixedly connected to one side of the traveling vehicle 2. The driver 3 is used to control the rotation of the driving rod 9. In this way, the driver 3 is arranged at the top, so that the driving rod 9 does not need to be put into the water, which greatly reduces the waterproof measures for the driver 3.

[0027] Specifically, the driver 3 includes a driving box 30, a driving rod 9 passing through the driving box 30, a base ring 38 is fixedly connected to the inner bottom of the driving box 30, a rotating sleeve 39 is rotatably connected to the base ring 38, a bevel gear ring 310 is fixedly connected to the outer side of the rotating sleeve 39, one side of the driving box 30 is rotatably connected to the rotating rod 34, one end of the rotating rod 34 is fixedly connected to the bevel gear 311, the bevel gear 311 is meshed with the bevel gear ring 310, a power device is provided at the other end of the rotating rod 34, the power device is used to drive the rotating rod 34 to rotate, a key groove is provided on the inner wall of the rotating sleeve 39, a key rod 91 is fixedly connected to the outer side of the driving rod 9, the driving rod 9 passes through the rotating sleeve 39, and the key rod 91 can slide back and forth up and down along the key groove, so that when the rotating sleeve 39 rotates, under the action of the key rod 91 and the key groove, the driving rod 9 rotates following the rotation of the rotating sleeve 39. With such a design, when the rotating rod 34 rotates, the rotating sleeve 39 also rotates under the meshing force of the bevel gear 311 and the bevel gear ring 310 , and the driving rod 9 rotates synchronously with the rotating sleeve 39 . The driving rod 9 drives the rotating shaft 82 to rotate under the action of the end 85 .

[0028] The power device can use different motors, but in this embodiment, in order to synchronize the descending speed of the conical drill and the steel casing 200, the power device is designed as follows: the power device includes a ratchet 35, the ratchet 35 is coaxially fixed with the rotating rod 34, a vertical dovetail groove 31 is provided on the outer wall of the drive box 30, a dovetail block is slidably connected in the dovetail groove 31, a spring is fixedly connected between the bottom of the dovetail groove 31 and the dovetail block, one side of the dovetail block is fixedly connected to the vertical rod 33, a first ratchet 37 is provided on one side of the vertical rod 33, and a second ratchet 36 is provided on the outer side of the drive box 30. The use and installation methods of the ratchet and the ratchet are prior art and will not be repeated here. Further, a cap 4 is provided on the top of the steel casing 200, and a striking plate 41 is fixedly connected to one side of the cap 4, and the striking plate 41 is located directly above the vertical rod 33. In this way, during the sinking process, the heavy object hits the cap 4, and the steel casing 200 and the cap 4 are simultaneously lowered, so that the vertical rod 33 is lowered, which can make the rotating rod 34 rotate a certain angle.

[0029] As an embodiment of the present invention, a telescopic positioning rod 812 is fixedly connected to the inner wall of the reinforcement box 81. The telescopic positioning rod 812 is an elastic telescopic rod. A positioning hole is provided on the rotating shaft 82. After the rotating shaft 82 rotates downward, the positioning rod 812 can be inserted into the positioning hole. The rotating shaft 82 can be limited by the positioning rod 812 to prevent the rotating shaft 82 from moving up during the removal of the driving rod. After the driving rod is removed, the first reinforcement device and the second reinforcement device do not need to be removed. After pouring underwater concrete, the first reinforcement device and the second reinforcement device form a whole with the steel casing 200. The first reinforcement device and the second reinforcement device can also enhance the strength of the poured concrete.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
