They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the utility model.

[0028] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Embodiment 1: As shown in the figure, the utility model comprises a metal clamp 1 installed outside a flexible pipe 3, a metal chain 7 connected to the metal clamp 1 at one end, and a fixing anchor 8 connected to the other end of the metal chain 7. In this embodiment, the two ends of the metal chain 7 are respectively fixedly connected to the metal clamp 1 and the fixing anchor 8 by welding. Among them, a rubber gasket 2 is provided on the inner wall of the metal clamp 1, and the rubber gasket 2 is fitted with the outer wall of the flexible pipe 3 to protect the flexible pipe 3 and reduce damage to the flexible sleeve.

[0030] The anchor 8 is made of a high-density metal material. The anchor 8 may preferably be made of, but not limited to, lead or iron to provide sufficient weight and inertial force. The anchor 8 can drive the flexible pipe 3 to sink underwater by its own weight and can penetrate into the underwater mud. Specifically, in this example, the end of the anchor 8 is provided with teeth 9, and the area cross-section of the teeth 9 is small. At the same time, the teeth 9 are particularly weighted to ensure that during the sinking process of the pipe, the teeth 9 can be embedded in the soft soil of the mud first, providing a more reliable fixing effect.

[0031] Embodiment 2: As shown in the figure, the utility model includes a metal clamp 1 installed outside the flexible pipe 3, a metal chain 7 connected to the metal clamp 1 at one end, and a fixed anchor 8 connected to the other end of the metal chain 7. The fixed anchor 8 can drive the flexible pipe 3 to sink into the water by its own weight and can penetrate into the underwater mud. The surfaces of the metal clamp 1, the metal chain 7 and the fixed anchor 8 are coated with an anti-corrosion coating. The anti-corrosion coating is one or more of an epoxy coating and a polyurethane coating. It can form a protective film on the metal surface, which can effectively prevent the underwater environment from corroding the metal.

[0032] In addition, a sacrificial anode 6 is designed and arranged on the nearshore side. The principle of the sacrificial anode 6 belongs to the prior art, and it is applied in the technical solution of the present application. The sacrificial anode 6 is installed in an easily accessible position near the revetment to facilitate regular inspection, maintenance and replacement. The sacrificial anode 6 is made of a metal material with excellent corrosion resistance and high activity, and is connected to the metal parts (metal wire 4 + metal coil 5) arranged on the flexible pipe 3 through a dedicated wire to form an efficient cathodic protection network. In order to ensure the maximum protection effect and maintenance convenience, the sacrificial anode 6 is arranged in the filling material, and the filling material is composed of a medium with good conductivity and moisture retention, which helps to reduce the soil resistivity and enhance the uniformity of current distribution, thereby improving the protection efficiency of the sacrificial anode 6 on the flexible pipe 3.

[0033] The preferred implementation method of this patent is as follows: fix the metal clamp 1 to the outside of the flexible pipe 3, put the pipe into the water, and use the deadweight of the anchor 8 to sink the pipe to the river bottom. Then, by dragging the tugboat longitudinally, the small anchor 8 is made to penetrate into the soil bottom mud, thereby fixing the pipe. In the whole process, there is no need for divers to directly participate in underwater operations, which reduces the construction risk and difficulty.

[0034] The utility model uses a metal clamp 1 on the outside of the pipeline, and a chain and a small fixed anchor 8 connected below the clamp, and uses the deadweight of the small fixed anchor 8 to sink the pipeline into the river bottom, and drags the small fixed anchor 8 into the bottom mud by longitudinal dragging, thus completing the installation of soft soil pipelines in deep water areas. Compared with traditional installation methods, this device not only reduces construction difficulty and risk, improves construction efficiency, saves costs, but also enhances environmental adaptability and durability.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
