Description

Technical Field

[0001] This utility model relates to the field of underwater engineering technology, and in particular to an underwater pipeline fixing pile with good fixing effect, high stability and function of reducing the impact of underwater turbulence. Background Technology

[0002] As crucial water resource management and flood control projects, reservoirs inevitably impact the surrounding ecological environment during their construction and operation. Enclosed water bodies like reservoirs and freshwater lakes are prone to vertical thermal stratification, hindering the downward transfer of oxygen from the upper water layers and resulting in poor water flow. Simultaneously, the deep water layers remain chronically oxygen-deficient, accelerating the release of endogenous pollutants from bottom sediments, leading to water quality deterioration. Therefore, in the remediation of deep water bodies, reoxygenation, fluid flow field optimization, and suppression of pollutant release from bottom sediments are key.

[0003] Existing technologies for treating enclosed water bodies include enhanced natural remediation, sediment dredging, and in-situ covering. Enhanced natural remediation, particularly through artificial reoxygenation, involves introducing air or pure oxygen into the water. Dissolved oxygen reacts with black and odorous substances at the bottom of the water body via an oxidation-reduction reaction, thus inhibiting the release of pollutants from the sediment. Enhanced natural remediation includes methods such as water aeration and reoxygenation, artificial addition of biological agents, and ecological restoration. Water aeration and reoxygenation, in particular, helps accelerate the restoration of the aquatic ecosystem to a normal state, offering good results and relatively low investment and operating costs. In recent years, deep-water aeration and reoxygenation technologies (such as DWBZ reoxygenation technology) have gradually become the preferred technology in the field of deep reservoir remediation. By injecting oxygen into the bottom layer of the water, the reoxygenated water rises to the surface, promoting the exchange of water between the upper and lower layers of the deep reservoir and optimizing the flow field of the enclosed water body. This accelerates the decomposition of organic matter in the overlying water, purifying the water quality, while simultaneously oxidizing the anoxic sediment at the bottom, thereby inhibiting the release of pollutants from the sediment and achieving integrated sediment and water management.

[0004] Currently, when constructing deep-water aeration and reoxygenation equipment, it is necessary to lay air supply pipelines underwater. The traditional method is to use clips to directly fix the pipelines to the bottom of the water, or to use ordinary piles to support the pipeline laying. The above methods mainly have the following problems: 1. Poor fixing effect, clips and ordinary piles are prone to loosening; 2. Poor stability, the pipeline is prone to dislocation due to the influence of underwater turbulence on the piles over a long period of time; 3. Cannot reduce the influence of underwater turbulence, clips and ordinary piles are prone to displacement under the influence of underwater turbulence when placed for a long time.

[0005] Therefore, there is an urgent need for an underwater pipeline fixing pile that has a good fixing effect, high stability, and the function of reducing the impact of underwater turbulence. Summary of the Invention

[0006] The present invention aims to solve the problems of poor fixing effect, poor stability, and inability to reduce the impact of underwater turbulence in the fixation of traditional buckles and ordinary piles. It provides an underwater pipeline fixing pile with good fixing effect, high stability, and the function of reducing the impact of underwater turbulence.

[0007] The underwater pipeline fixing pile of this utility model is characterized in that the fixing pile includes a pile body, a through hole, a fixing nail and a chain. A pipe buckle is provided at the top of the pile body, and an air supply pipe is installed in the pipe buckle. A chain is connected to the bottom edge of the pile body. A through hole is provided inside the pile body, and the openings at both ends of the through hole are located on the side wall of the pile body. The fixing nail is provided on the bottom surface of the pile body and is perpendicular to the bottom surface of the pile body.

[0008] The aforementioned through holes are two or four, with two through holes arranged in a cross shape and four through holes arranged in a grid shape.

[0009] The side wall of the pile at the opening of the through hole is a concave surface, which reduces the impact force on the side of the pile when underwater turbulence enters the through hole.

[0010] The fixing nail has upward barbs on its sidewall to increase its grip and prevent the pile from loosening.

[0011] During construction, the pile is first driven into the water. The fixing nails at the bottom of the pile fix the pile to the bottom of the water. The chain is then fixed to the bottom of the water with ground nails to complete the pile fixing. Then the gas pipeline is placed in the buckle at the top of the pile and the buckle is closed to complete the installation.

[0012] This utility model of underwater pipeline fixing pile has a reasonable structure, scientific design, and good fixing effect. It uses fixing nails and chains to achieve double fixing, which effectively prevents the pile from loosening. Through holes are set on the pile to reduce the impact of underwater turbulence on the pile and reduce the displacement of the pile, thereby improving the stability of the pile itself.

[0015] The components include: 1. Pile body; 2. Through hole; 3. Fixing nail; 4. Barb; 5. Chain. Detailed Implementation

[0016] Example 1: An underwater pipeline fixing pile includes a pile body 1, a through hole 2, a fixing nail 3, and a chain 5. A pipeline buckle is provided at the top of the pile body 1, and an air supply pipeline is installed in the pipeline buckle. A chain 5 is connected to the bottom edge of the pile body 1. A through hole 2 is provided inside the pile body 1, and the two ends of the through hole 2 are located on the side wall of the pile body 1. The fixing nail 3 is provided on the bottom surface of the pile body 1 and is perpendicular to the bottom surface of the pile body 1.

[0017] There are two or four through holes 2. Two through holes 2 are arranged in a cross shape, and four through holes 2 are arranged in a grid shape. The side wall of the pile body 1 at the opening of the through hole 2 is concave to reduce the impact force on the side of the pile body 1 when underwater turbulence enters the through hole 2. The fixing nail 3 has upward barbs 4 on its side wall to increase the grip of the fixing nail 3 and prevent the pile body 1 from loosening.

[0018] During construction, first, drive pile 1 into the bottom of the water. Fixing nail 3 at the bottom of pile 1 will fix pile 1 to the bottom of the water. Then, use ground nails to fix chain 5 to the bottom of the water. This will complete the fixing of pile 1. Then, place the gas pipeline into the buckle at the top of pile 1 and close the buckle to complete the installation.
