Description

Technical Field

[0001] This invention relates to the field of emergency road paving, specifically to a shallow water road paving system and paving method. Background Technology

[0002] To ensure that wheeled and tracked vehicles can smoothly cross the coastal mudflats from the barge to the shore above the waterline, large-area access slabs need to be quickly laid on the mudflats as temporary access.

[0003] The tidal flats have a soft, sandy foundation. To ensure vehicle passage, the paved walkways need sufficient area and rigidity to distribute the loads from wheels and tracks, resulting in a relatively heavy weight for each paved panel. Existing tidal flat walkways are mainly used as temporary access for power facility construction and oil extraction. The panels are assembled manually, piece by piece, with the aid of a crane, making the assembly process slow.

[0004] Existing methods for paving shallow water surfaces include guide tube traction and direct towing. For guide tube traction, at low tide, the channel slab between the waterline and the barge can be laid directly using guide tubes. However, at intermediate or high tide, the barge's mooring position is relatively close to the shore, and the roller traction method can only complete the paving from the waterline to the barge area. The paving from the barge to the sea area is then completed by the barge reversing. The roller traction process requires first pulling the channel slab halfway, disconnecting it at the end of the original channel slab, connecting the original end channel slab to the remaining channel slab on the barge, and then completing the paving of the sea area by the barge reversing. This method requires temporary disconnection and reconnection of the channel slab, a cumbersome process that requires anti-slip strips on both the upper and lower surfaces of the channel slab, which is detrimental to reducing the weight of the channel slab structure.

[0005] The direct towing method involves pulling the slabs directly from the transport ship to the beach, then using a barge to carry them to the sea for installation, and finally using the barge to move them back to complete the installation. However, this method results in direct friction between the slabs and the mudflats, and the frictional resistance is highly uncertain due to variations in foundation conditions and factors such as pits and protrusions in the ground. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides a shallow water pavement system and method, which solves the problem that the channel slabs on the ship cannot be laid simultaneously towards the shore and towards the water. The channel slabs can be laid at full tide, and there is no relative movement between the channel slabs and the ground during the laying process, which reduces the impact of the laying process on the laying traction force.

[0007] The objective of this invention is achieved through the following technical solution: a shallow water pavement paving system, comprising:

[0008] The traction system is connected to the guidance system via a traction cable.

[0009] The guidance system is connected to the traction system at its front end via a traction cable and to the channel plate storage system via a laying device, which includes a first connection point and a second connection point.

[0010] The channel plate storage system includes upper and lower layers, each containing channel plates. The channel plates stored in the upper layer of the channel plate storage system are connected to the first connection point of the laying device, and the channel plates stored in the lower layer of the channel plate storage system are connected to the second connection point of the laying device.

[0011] When the traction force acts on the first connection point, it causes the upper channel plate in the channel plate storage system to move; when the traction force acts on the second connection point, it causes the lower channel plate in the channel plate storage system to move.

[0012] The traction system, guidance system, and access panel storage system are arranged on the barge in a front-to-back order.

[0013] Preferably, the traction system can be a tractor vehicle.

[0014] Preferably, the tractor is equipped with a hydraulic coiling device.

[0015] Preferably, the guide system is reel-shaped, with a connecting rod on one side for connection to the traction system. A chain is installed on the guide system reel, and the two ends of the chain are connected to the upper and lower layers of the channel plate storage system.

[0016] Preferably, the channel plate storage system is a double-layer support structure, which is formed by splicing together multiple fixed supports.

[0017] Preferably, the double-layer support of the channel plate storage system is equipped with an adjustable support with adjustable vertical height.

[0018] In addition to providing a shallow water pavement system, this invention further provides a method for paving shallow water pavements using the aforementioned shallow water pavement system, comprising the following steps:

[0019] Step 1: After the barge is beached, determine the length of the channel slabs to be laid based on the distance from the barge to the waterline.

[0020] Step 2: Move the traction system off the barge and lower the upper channel plate of the traction channel plate storage system off the barge to the waterline.

[0021] Step 3: The barge sails out to sea and pulls the lower channel slab of the channel slab storage system to lay it on the shallows.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] This invention provides a shallow water pavement system and method for rapidly laying channel slabs in tidal flat areas, enabling the rapid laying of a certain length of channel slabs from the waterline to the sea. This invention achieves rapid laying of large-area channel slabs in tidal flat areas by placing the channel slabs in layers within a laying support frame. The upper layer of channel slabs is laid using guide tubes, while the lower layer is laid by a barge moving backward. This enables the rapid laying of large-area channel slabs in tidal flat areas, especially in areas with weak load-bearing capacity such as sandy beaches and swamps.

[0024] Using the road paving system and method provided by this invention, regardless of whether it is high tide, intermediate tide, or low tide, the barge can lay the channel slab from the barge to the waterline by using a guiding device after it has run aground, and it can lay the channel slab backward by reversing the barge. During the laying process, the channel slab does not need to be broken or connected in the middle, the upper and lower surfaces of the channel slab can be different, and the channel slab does not slide relative to the ground during the laying process. Therefore, the laying process is not affected by ground factors, and the laying operation is highly controllable. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0032] The present invention provides a shallow water pavement paving system, characterized in that: the paving system includes:

[0033] The traction system is connected to the guidance system 3 via a traction cable;

[0034] The guide system 3 is connected to the traction system via a traction cable at its front end, and to the channel plate storage system 4 via a laying device, which includes a first connection point and a second connection point.

[0035] The channel plate storage system 4 includes upper and lower layers, each layer storing channel plates 5. The channel plates 5 stored in the upper layer of the channel plate storage system 4 are connected to the first connection point of the laying device, and the channel plates 5 stored in the lower layer of the channel plate storage system 4 are connected to the second connection point of the laying device.

[0036] When the traction force acts on the first connection point, it causes the upper channel plate in the channel plate storage system 4 to move. When the traction force acts on the second connection point, it causes the lower channel plate in the channel plate storage system 4 to move.

[0037] The traction system, guidance system 3, and channel plate storage system are arranged on barge 1 in a front-to-back order.

[0038] like Figures 1 to 2 As shown, in one embodiment of the present invention, the traction system may be a tractor 2. The tractor 2 is equipped with a hydraulic coiling device.

[0039] like Figure 3 As shown, in one embodiment of the present invention, the guide system 3 is reel-shaped, with a connecting rod on one side for connection to the traction system. A chain is mounted on the reel, with both ends connected to the upper and lower layers of the channel plate storage system 4. The portion of the reel chain connecting to the upper layer of the channel plate storage system 4 is the first connection point, and the portion connecting the reel chain to the lower layer of the channel plate storage system 4 is the second connection point. When the traction system pulls the reel forward, the reel rotates forward, causing the first connection point to be stressed and pulling the upper channel plate 5. When the reel receives external force and rotates backward, it causes the second connection point to be stressed and pulls the lower channel plate 5.

[0040] like Figure 3As shown, in one embodiment of the present invention, the channel panel storage system 4 is a double-layer support structure, assembled from multiple fixed supports 6. The double-layer support of the channel panel storage system 4 is equipped with a longitudinally adjustable support 7. This longitudinally adjustable support 7 uses a hydraulic system, allowing for height adjustment to ensure a smooth transition between the upper channel panels 5 and the barge deck during traction. The fixed supports 6 are spliced ​​structures, allowing the channel panels to be stored in upper and lower sections, and providing horizontal positioning for the channel panels 5 during installation. All channel panels 5 are placed in two large layers on the barge's channel panel storage system 4. The upper channel panels are installed using a guide tube traction method, while the lower channel panels are installed by the barge reversing. The upper and lower channel panels can be placed horizontally or folded vertically.

[0041] In addition to providing a shallow water pavement system, the present invention further provides a method for paving a shallow water pavement using the aforementioned shallow water pavement system, comprising the following steps:

[0042] Step 1: After barge 1 is beached, determine the length of the channel slab 5 to be laid based on the distance from barge 1 to the waterline.

[0043] Step 2: Move the traction system off the barge 1 and lower the upper channel plate 5 of the traction channel plate storage system 4 to the waterline.

[0044] Step 3: Barge 1 sails towards the sea and pulls the lower channel slab of the channel slab storage system 4 to lay it on the shallows.

[0045] In one embodiment of the present invention, when using as follows Figures 1 to 3 The laying system shown includes a transport barge 1, a tractor 2, a guidance system 3, and a channel plate storage system 4.

[0046] The transport barge 1 is mainly used for transporting the tractor 2, the guidance system 3, the channel slab storage system 4, and the channel slab 5. The tractor 1 is used to pull the guidance system 3. The guidance system 3 assists in the laying of the channel slab 5 when pulling it.

[0047] The method for paving shallow water surfaces using the above system is as follows:

[0048] Step 1: Barge 1 is beached. Based on the distance from the barge to the waterline, the length of the channel slab 5 that needs to be laid on the upper layer of the channel slab storage system 4 is determined.

[0049] Step 2: The tractor unit disembarks and moves the guide winch forward, pulling the upper passageway slab off the ship to the waterline. Alternatively, the tractor unit can first travel to the waterline and then use its onboard hydraulic winch to pull the upper passageway slab off the ship to the waterline. Figure 4 As shown;

[0050] Step 3: Barge 1 sails towards the sea, driving the traction reel backward to pull out the lower channel slab, completing the laying of the lower channel slab. Figure 5 As shown.

[0051] This embodiment solves the problem of channel slab laying under full high tide conditions by arranging the channel slabs in two layers on the channel slab storage system 4. After the barge has run aground, the channel slab can be laid forward using a guiding device to reach the waterline, and backward using the barge's reversing motion. During the laying process, the channel slabs do not need to be broken or connected in the middle, and they do not slide relative to the ground. The laying process is unaffected by ground factors, resulting in high controllability of the laying operation.

[0052] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
