Description

Technical Field

[0001] This utility model relates to a pipe support device for laying drainage pipelines in shallow sea sections. Background Technology

[0002] When laying large-diameter pipelines in shallow waters (such as the intertidal zone), large pipelaying vessels cannot enter due to the shallow water level, and the complex seabed geological conditions (such as thick silt layers) often result in insufficient load-bearing capacity and poor stability with traditional pontoons or simple supports. During the process of towing the pipeline from land to sea, the friction between the pipeline and the supporting structure is enormous, which can easily damage the pipeline's anti-corrosion layer and even lead to towing failure.

[0003] Therefore, a pipe support device for laying drainage pipelines in shallow sea areas is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the existing defects and provide a pipe support device for laying drainage pipelines in shallow sea sections, which has a stable structure and low friction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe support device for laying drainage pipelines in shallow sea areas, comprising a steel pipe pile foundation, a concrete base, a steel pipe support, and a pulley block; The steel pipe pile foundation is driven into the shallow seabed bearing stratum. The concrete base is poured and fixed on the top of the steel pipe pile foundation. The steel pipe support is fixedly installed above the concrete base. The pulley block is rotatably installed on the top of the steel pipe support to support the pipeline and guide its sliding.

[0006] Preferably, the steel pipe pile foundation consists of a pile group structure composed of multiple steel pipe piles.

[0007] Preferably, the concrete base is pre-embedded with embedded parts that connect to the steel pipe pile foundation and the steel pipe support, thereby achieving a rigid connection.

[0008] Preferably, the pulley assembly includes a plurality of pulleys arranged along the axial direction of the pipe, and the surface of the pulleys is covered with a rubber layer to protect the anti-corrosion layer of the pipe.

[0009] Preferably, the top of the steel pipe support has an arc-shaped structure, which cooperates with the pulley block to limit the movement of the pipe.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: This pipe support device for laying drainage pipelines in shallow sea areas utilizes a steel pipe pile foundation driven into the bearing stratum of the shallow seabed. A concrete base is poured and fixed at the top of the steel pipe pile foundation, and a steel pipe support is fixedly installed above the concrete base. A pulley system is rotatably installed at the top of the steel pipe support to support the pipeline and guide its sliding. The structure is stable: the "steel pipe pile + concrete base" foundation solves the problem of low bearing capacity in shallow sea soft soil foundations and provides strong resistance to wave impact. It also offers good drag reduction: by using a pulley system to support the pipeline, sliding friction is transformed into rolling friction, significantly reducing the traction resistance when the pipeline enters the water and protecting the outer anti-corrosion layer of the pipeline. Finally, it facilitates construction: it provides a stable construction platform for pipeline welding, allowing for long-distance pipeline laying in shallow water areas without the need for large pipe-laying vessels.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1 As shown, a pipe support device for laying drainage pipelines in shallow sea areas includes a steel pipe pile foundation 1, a concrete base 2, a steel pipe support 3, and a pulley block 4. The steel pipe pile foundation 1 is driven into the bearing stratum of the shallow seabed. The steel pipe pile foundation 1 is composed of multiple steel pipe piles forming a pile group structure to enhance the overturning resistance.

[0015] Specifically, the system uses steel pipe pile foundations set on the seabed in shallow waters. A concrete base is fixedly connected to the top of the steel pipe piles, and steel pipe supports are installed on the concrete base. A pulley system is installed at the top of the steel pipe supports. The pipeline to be laid is placed on the pulley system for welding and assembly. After welding, the pipeline is pulled along the pulley system into the water using traction equipment. The combination of steel pipe piles and a concrete base provides a stable foundation in shallow waters. The pulley system significantly reduces the frictional resistance when the pipeline slides into the water, solving the technical problems of unstable foundations and high dragging resistance in long-distance laying of large-diameter pipelines in shallow waters.

[0016] Specifically, the concrete base 2 is poured and fixed at the top of the steel pipe pile foundation 1, and the steel pipe support 3 is fixedly installed above the concrete base 2. The concrete base 2 is pre-embedded with embedded parts that connect with the steel pipe pile foundation 1 and the steel pipe support 3 to achieve a rigid connection.

[0017] Specifically, the pulley block 4 is rotatably mounted on the top of the steel pipe support 3 to support the pipe 5 and guide its sliding. The pulley block 4 includes multiple pulleys arranged along the axial direction of the pipe, and the surface of the pulleys is covered with a rubber layer to protect the anti-corrosion coating of the pipe. The top of the steel pipe support 3 has an arc-shaped structure, which cooperates with the pulley block 4 to limit the movement of the pipe 5.

[0018] Specifically, the steel pipe pile foundation 1, acting as a deep foundation, penetrates the shallow, soft soil layer of the sea, transferring the load to the deeper foundation and ensuring the overall structure's resistance to uplift and overturning. The concrete base 2, located atop the steel pipe piles, serves as a connecting element, linking multiple steel pipe piles into a unified structure and providing a horizontal support surface. The steel pipe support 3, constructed from welded steel sections or pipes, is installed on the concrete base to elevate the pipeline and adapt to tidal changes. The pulley system 4, installed at the top of the steel pipe support, places the pipeline on the pulleys, transforming traditional sliding friction into rolling friction, significantly reducing traction.

[0019] Specifically, steel pipe pile foundation 1 is driven into the seabed, and concrete base 2 sits on the steel pipe piles. Steel pipe support 3 is welded to the embedded plate of the concrete base. Pulley block 4 is installed on top of the steel pipe support via a rotating shaft. Pipe 5 is placed on the pulleys, with a traction cable connected to its front end. As the traction operation proceeds, the pipe slides into the sea under the rolling action of the pulleys.

[0020] During construction, steel pipe piles are first driven into predetermined locations in the shallow sea, a concrete foundation is poured, and steel pipe supports and pulley blocks are installed. Then, the pipeline to be laid is hoisted onto the pulley blocks, and the pipe ends are welded and treated with anti-corrosion coating. After welding, traction equipment (such as a winch) is activated, and the pipeline, supported by the rolling motion of the pulley blocks, is smoothly slid into the seawater, achieving continuous pipeline laying.

[0021] The drainage pipeline laying in this shallow sea section utilizes a pipe support device. Steel pipe piles (1) are driven into the bearing stratum of the shallow seabed. A concrete base (2) is poured and fixed to the top of the steel pipe piles (1). A steel pipe support (3) is fixedly installed above the concrete base (2). A pulley system (4) is rotatably installed on top of the steel pipe support (3) to support the pipeline (5) and guide its sliding. The structure is stable: the "steel pipe pile + concrete base" foundation solves the problem of low bearing capacity in shallow sea soft soil foundations and provides strong resistance to wave impact. It also offers good drag reduction: by using a pulley system to support the pipeline, sliding friction is converted to rolling friction, significantly reducing the traction resistance when the pipeline enters the water and protecting the outer anti-corrosion layer. Construction is convenient: it provides a stable construction platform for pipeline welding, allowing for long-distance pipeline laying in shallow waters without the need for large pipe-laying vessels.

[0022] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
