Description

Technical Field

[0001] This invention belongs to the technical field of breakwaters for high-temperature gas-cooled reactor nuclear power plants, specifically relating to an underwater laying device for geosynthetic materials for breakwaters of high-temperature gas-cooled reactor nuclear power plants. Background Technology

[0002] The geological conditions of the sea area where high-temperature gas-cooled reactor nuclear power plants are located are quite complex. During breakwater construction, a large amount of geosynthetic material is laid on the surface of the original seabed mud for foundation treatment. The current industry standard method is to secure the ends of the geosynthetic material with sandbags or gravel bags, slowly lower it along the ship's side to the sea surface, and then throw sandbags into the middle area of ​​the geosynthetic material to press it down onto the seabed. However, geosynthetic materials are mostly made of synthetic fibers, resembling a cloth. When using sandbags or gravel bags as end ballast, they are easily affected by waves, currents, and uneven throwing of the sandbags or gravel bags. This can easily lead to the geosynthetic material not being securely fixed at the beginning of the laying, resulting in overturning or slippage, which in turn affects the quality of the foundation treatment. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art, and to provide a new technical solution for an underwater laying device for geosynthetic materials of breakwaters in high-temperature gas-cooled reactor nuclear power plants.

The first end of the rope is fixed to the anchor, and a knot is formed in the middle of the rope and fastened to one of the fixed areas. When the geosynthetic material is pulled along the knot in a first direction, the knot tightens around the fixed area; when the second end of the rope is pulled along a second direction, the rope disengages from the fixed area. The second end of the rope is fixed to the anchor float, which is positioned at a preset location. Each of the anchors is fixed to the original mud layer on the seabed, so that the second end of the geosynthetic material is laid flat on the surface of the original mud layer on the seabed.

[0013] Optionally, the anchor includes an anchor rod, an anchor arm, and an anchor claw, wherein the anchor arm is fixed to the end of the anchor rod, and the anchor claw is fixed to the end of the anchor arm away from the anchor rod.

[0024] Specifically, the underwater laying device for the geosynthetic material of the breakwater of the high-temperature gas-cooled reactor nuclear power plant includes: Geotextile 1 and roll 2, wherein the first end of geotextile 1 is wound around the roll 2; The geotextile 1 includes an anchor 3, a rope 4, and an anchor float. Multiple fixed areas 11 are provided at the second end of the geotextile 1 along its width direction. The anchor 3, the rope 4, and the fixed areas 11 are arranged in a one-to-one correspondence. The first end of the rope 4 is fixed to the anchor 3. A knot is formed in the middle of the rope 4 and fastened to the fixed area 11. When the geotextile 1 is pulled along the first direction, the knot tightens the fixed area 11. When the second end of the rope 4 is pulled along the second direction, the rope 4 disengages from the fixed area 11. The second end of the rope 4 is fixed to the anchor float, which is set at a preset position, for example, at a certain position on the water surface 8.

[0025] See Figure 1Each of the anchors 3 is fixed to the original mud layer 6 on the seabed, so that the second end of the geotextile 1 is laid flat on the surface of the original mud layer 6 on the seabed. The drum 2 sinks into the seabed and moves along the laying direction of the geotextile 1. The geotextile 1 is pulled and fastened in the first direction, and the first end of the geotextile 1 is spread out on the surface of the original mud layer 6 on the seabed. The second end of the rope 4 is pulled in the second direction to retrieve the rope 4 and the anchors 3.

[0026] In this embodiment, each anchor 3 is fixed to the original mud layer 6 on the seabed, so that the second end of the geosynthetic material 1 is laid flat on the surface of the original mud layer 6 on the seabed. The drum 2 sinks into the seabed and moves along the laying direction of the geosynthetic material 1. The geosynthetic material 1 is pulled and fastened in the first direction, and the first end of the geosynthetic material 1 is unfolded on the surface of the original mud layer 6 on the seabed. The second end of the rope 4 is pulled in the second direction to retrieve the rope 4 and the anchor 3. Therefore, when laying the geosynthetic material 1, the underwater laying device for the breakwater geosynthetic material of the high-temperature gas-cooled reactor nuclear power plant can effectively avoid problems such as uneven laying and easy slippage caused by the unstable fixing of the underwater geosynthetic material during the laying of the breakwater, ensuring the flatness of the geosynthetic material 1 and thus improving the quality of foundation treatment.

[0027] Furthermore, the geotextile material 1 laid using the underwater laying device for the breakwater geotextile of this high-temperature gas-cooled reactor nuclear power plant has advantages such as convenient operation, good construction quality, high safety, and unaffected by sea conditions. Moreover, the anchorage 3 is recyclable and reusable, which greatly saves the material cost of sandbags or gravel bags and the labor cost of filling, and can be promoted and applied to other engineering fields.

[0028] Optionally, the underwater laying device for the geosynthetic material of the breakwater of the high-temperature gas-cooled reactor nuclear power plant also includes a construction vessel 7; the height of the drum 2 is adjustable and fixed to the construction vessel 7; the construction vessel 7 moves and drives the drum 2 to move along the laying direction of the geosynthetic material 1.

[0029] In the above embodiment, the construction vessel 7 drives the drum 2 to move along the laying direction of the geotextile 1. The operation is very simple and facilitates the stable movement of the drum 2, thereby achieving the smooth laying of the geotextile 1. Moreover, adjusting the height of the drum 2 by the construction vessel 7 is very simple, which helps to accurately control the position of the drum 2 and further facilitates the smooth laying of the geotextile 1.

[0030] Optionally, the underwater laying device for the geosynthetic material of the breakwater of the high-temperature gas-cooled reactor nuclear power plant also includes a winch 10, which is installed on the construction vessel 7 and connected to the drum 2; the winch 10 is used to drive the drum 2 to sink to the seabed or rise from the seabed to a preset height.

[0031] In the above embodiments, the winch 10 helps to quickly lower the drum 2 to the seabed or raise it from the seabed to a preset height, thereby improving the laying efficiency of the geotextile 1. Moreover, the winch 10 can better fix the drum 2, thereby driving the drum 2 to move stably, so as to ensure the flatness of the geotextile 1.

[0032] Optionally, the underwater laying device for the geosynthetic material of the breakwater of the high-temperature gas-cooled reactor nuclear power plant also includes a first cable 91 and a second cable 92. The drum 2 is fixed to the winch 10 by the first cable 91 and to the construction vessel 7 by the second cable 92.

[0033] In the above embodiment, the first cable 91 and the second cable 92 can stably fix the drum 2, ensuring the stability and flatness of the drum 2 during the laying of the geotextile 1.

[0034] Optionally, the anchor float includes a first anchor float 51 and a second anchor float 52, the first anchor float 51 and the second anchor float 52 are respectively disposed on opposite sides of the second end of the geotextile 1, the second end of the rope 4 near the first anchor float 51 is fixed to the first anchor float 51; the second end of the rope 4 near the second anchor float 52 is fixed to the second anchor float 52.

[0035] In the above embodiment, the first anchor float 51 and the second anchor float 52 help to better secure the second end of the rope 4, ensuring that the first end of the geotextile 1 is stably fixed to the anchor 3. Moreover, the first anchor float 51 and the second anchor float 52 enable the rapid retrieval of the anchor 3 and the rope 4 after the geotextile 1 is laid, improving the laying efficiency of the geotextile 1.

[0036] Optionally, two fixed areas 11 are respectively provided at the two corners of the second end of the geotextile 1, and multiple fixed areas 11 are provided at intervals between the two fixed areas 11.

[0037] In the above embodiment, by setting multiple fixed areas 11, it helps to ensure the flat laying of the second end of the geotextile 1. Moreover, the second end of the geotextile 1 is firmly fixed to the anchor 3, which can effectively avoid problems such as uneven overall laying and easy slippage caused by the geotextile 1 not being firmly fixed, thereby helping to ensure the laying quality of the geotextile 1.

[0038] Optionally, the distance between adjacent fixed areas 11 is 3m-5m. This helps to better fix the second end of the geotextile 1, and also ensures the flatness of the second end of the geotextile 1, which helps to achieve the flatness of the overall laying of the geotextile 1.

[0039] Optionally, a through hole 101 is provided on the fixed area 11, and the middle part of the rope 4 passes through the through hole 101 to form a fastening. The through hole 101 facilitates the quick setting of the fastening, ensuring a stable connection between the rope 4 and the geotextile 1. At the same time, it also allows for the retrieval of the anchor 3 and the rope 4 after the geotextile 1 has been laid.

[0040] Optionally, the fastener is a trailer fastener. Trailer fasteners are easy to set up and easy to unset up, thus better securing the geotextile 1 during installation and allowing for quick retrieval of the anchor 3 and rope 4 after installation. This simple operation significantly improves the efficiency of geotextile 1 installation. The fastener can also be a sailor's fastener.

[0041] Optionally, see Figure 3 The anchor 3 includes an anchor rod 31, an anchor arm 32, and an anchor claw 33. The anchor arm 32 is fixed to the end of the anchor rod 31, and the anchor claw 33 is fixed to the end of the anchor arm 32 away from the anchor rod 31. This allows the anchor 3 to be more firmly fixed to the original mud layer 6 on the seabed, thereby achieving the fixation of the geotechnical material 1.

[0042] Preferably, the anchor rod 31 and anchor arm 32 of the anchor 3 are both made of φ32 threaded steel, and the anchor rod 31 and anchor arm 32 are welded together. The anchor claw 33 is made of 15mm steel plate cut into a triangle and welded to the anchor arm 32. This simplifies the structure of the anchor 3, improves the strength of the anchor 3, and helps to achieve a firm fixation of the geotextile 1.

[0043] In one specific implementation, the second end of the geotextile 1 is fixed by a pull anchor. A corresponding number of anchors 3 are installed according to the specific width of each section of geotextile to be laid. For example, if the width of geotextile 1 is 25m, six anchors 3 and six ropes 4 are used to ensure reliable fixing of the second end of geotextile 1. Furthermore, trailer hooks or sailor's hooks enable the anchors 3 to be recyclable.

[0044] The original mud layer 6 on the seabed in the area where the breakwater of the high-temperature gas-cooled reactor nuclear power plant is laid mainly consists of fine sand and silty soil. The anchor 3 is fixed to the second end of the geotextile 1. The anchor 3 can be smoothly embedded in the mud to firmly fix the second end of the geotextile 1, thereby achieving the effect of laying flat and without slippage.

[0045] In this embodiment of the application, the underwater laying device for the geosynthetic material of the breakwater of a high-temperature gas-cooled reactor nuclear power plant is implemented according to the following steps when laying the geosynthetic material: First, fix the first end of the geotextile material 1 to the drum 2, and rotate the drum 2 to wind up the geotextile material 1 to a predetermined length. A fixed area 11 is set at predetermined intervals at the second end of the geotextile material 1, and each fixed area 11 is connected to an anchor 3, with each anchor 3 connected to the geotextile material 1 for the same length. Next, use a rope 4 to connect the anchor 3, the geotextile material 1, and the anchor float. For example, both ends of the rope 4 are fixedly connected to the anchor 3 and the anchor float respectively, which can be secured with a knot, while the middle of the rope 4 is connected to the geotextile material 1 with a sailor's knot (trailer knot).

[0046] Secondly, after the construction vessel 7, which is sailing on the water surface 8, is accurately positioned, it is anchored and fixed. Then, the winch 10 is driven to sink the drum 2 along with the geotextile material 1 to the seabed and move the construction vessel 7 along the laying direction. At this time, the trailer buckle (sailor buckle) is subjected to force in the first direction, and the buckle is pulled tighter and tighter, and the anchor 3 is pulled to firmly fix the geotextile material 1.

[0047] Finally, during the laying process, sandbags are thrown to hold down the geosynthetic material and prevent it from drifting. After the laying is completed, the second end of the rope 4 is pulled in the second direction, that is, the sailor's buckle (trailer buckle) is pulled vertically in the direction of anchor drift. The sailor's buckle (trailer buckle) between the rope 4 and the geosynthetic material 1 is released, and the anchor is successfully lifted and retrieved.

[0048] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
