Description

Technical Field

[0001] This invention relates to the field of long-distance pipeline tunnel construction technology, and particularly to a pipeline construction equipment and method for tunnels. Background Technology

[0002] With the continuous development of my country's petrochemical industry and the rapid construction of national oil reserve bases, my country's crude oil storage tanks are developing towards larger sizes and multiple tanks. Consequently, the transportation of crude oil and other oil products has become a top priority. Based on low cost, speed, and zero pollution, long-distance pipelines have become an important way to transport various oil products to various stations, storage tanks, and wharves.

[0003] Long-distance pipeline projects inevitably require tunnels to traverse mountainous areas. These tunnels come in various forms, including straight, curved, and zigzag, presenting technical challenges such as limited space, narrow working areas, and high construction risks. In particular, the use of existing tunnels results in low rates of mechanized operations during tunnel construction, significantly reducing construction efficiency. Summary of the Invention

[0004] To address the problems in the prior art, this application proposes a tunnel pipeline construction equipment and a tunnel pipeline construction method to solve the problem of low efficiency in tunnel pipeline construction.

[0005] This invention provides a tunnel pipeline construction device, which includes:

[0006] A prefabricated pipeline assembly, installed outside the tunnel, for prefabricating single-section pipelines into long-distance pipelines; and

[0007] A pipeline conveying device is installed outside the tunnel entrance of the tunnel and is used to transport the long-distance pipeline into the tunnel.

[0008] As a further improvement to the above technical solution:

[0009] The aforementioned tunnel pipeline construction equipment further includes a pipeline conveying device comprising a first mounting frame and a main pipe pusher mounted on the first mounting frame, the main pipe pusher being used to convey the long-distance pipeline into the tunnel.

[0010] The aforementioned tunnel pipeline construction equipment further includes a pipeline conveying device that also includes a secondary pipe pusher mounted on the first mounting frame. The secondary pipe pusher and the main pipe pusher are installed at intervals along the axial direction of the long-distance pipeline, and the secondary pipe pusher is used to restrict the long-distance pipeline from moving along its axial direction.

[0011] The aforementioned tunnel pipeline construction equipment further includes a prefabricated pipeline device comprising a second mounting frame and a prefabrication mechanism mounted on the second mounting frame, the prefabrication mechanism being used to prefabricate a single pipeline section into the long-distance pipeline.

[0012] The aforementioned tunnel pipeline construction equipment further includes, in a more detailed manner, a pre-set mechanism comprising an assembly assembly for assembling the single pipeline section, a fully automatic welding assembly for welding the single pipeline section, a mechanical corrosion protection assembly for corrosion protection of the long-distance pipeline, and a non-destructive testing assembly for inspecting the long-distance pipeline.

[0013] Furthermore, in the aforementioned tunnel pipeline construction equipment, multiple guiding and conveying devices are installed at intervals along a preset direction inside the tunnel, and these multiple guiding and conveying devices are used to transport the long-distance pipeline along the preset direction.

[0014] The aforementioned tunnel pipeline construction equipment further includes a guiding and conveying device comprising a third mounting frame that can be fixedly installed inside the tunnel and multiple sets of rollers mounted on the third mounting frame.

[0015] The aforementioned tunnel pipeline construction equipment further includes a guiding and conveying device comprising three sets of rollers mounted on the third mounting frame. One set of rollers is horizontally rotatably mounted on the third mounting frame, while the other two sets of rollers are symmetrically tilted and rotatably mounted on the third mounting frame. The three sets of rollers form a limiting groove that restricts the long-distance pipeline from moving in directions other than its axial direction.

[0016] Furthermore, in the aforementioned tunnel pipeline construction equipment, the rollers are made of polyurethane material.

[0017] Another aspect of the present invention provides a method for constructing pipelines inside a tunnel, the method comprising the steps of:

[0018] Prefabricate single-section pipes into long-distance pipelines;

[0019] The long-distance pipeline will transport the goods into the tunnel.

[0020] The above-mentioned technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of the present invention can be achieved.

[0021] This invention provides a tunnel pipeline construction equipment and method, which, compared with existing technologies, have at least the following advantages: When tunnel pipeline construction is required, a prefabrication pipe device located outside the tunnel first prefabricates single pipe sections into long-distance pipelines. Then, a pipeline conveying device transports the long-distance pipelines into the tunnel, thereby completing the tunnel pipeline construction. Using this tunnel pipeline construction equipment, since both the prefabrication pipe device and the pipeline conveying device are located outside the tunnel, it avoids the technical difficulties caused by limited space inside the tunnel, such as narrow working areas and high construction risks. Furthermore, this tunnel pipeline construction equipment can improve the mechanization rate of tunnel construction and significantly increase construction efficiency.

[0035] The invention will now be further described with reference to the accompanying drawings.

[0036] This invention provides a tunnel pipeline construction device to solve the problem of low efficiency in tunnel pipeline construction.

[0037] like Figure 1 As shown in the embodiment of the present invention, the tunnel pipeline construction equipment includes a prefabricated pipeline device and a pipeline conveying device. The prefabricated pipeline device is used to prefabricate a single section of pipeline 2 into a long-distance pipeline 6. The pipeline conveying device is installed at the tunnel 5 entrance of the tunnel 5 and is used to convey the long-distance pipeline 6 into the tunnel 5.

[0038] When pipeline construction is required inside the tunnel, the prefabrication pipeline device located outside the tunnel 5 first prefabricates the single-section pipeline 2 into a long-distance pipeline 6, and then the pipeline transportation device transports the long-distance pipeline 6 into the tunnel 5, thereby completing the pipeline construction inside the tunnel.

[0039] Using the tunnel pipeline construction equipment provided in this embodiment of the invention for tunnel pipeline construction, since the prefabricated pipeline device and the pipeline conveying device are both located outside the tunnel 5, the technical difficulties such as narrow working surface and high construction risk caused by the limited space inside the tunnel 5 can be avoided. In addition, the tunnel pipeline construction equipment provided in this embodiment of the invention can improve the mechanization rate of tunnel 5 construction and greatly improve construction efficiency.

[0040] The tunnel pipeline construction equipment provided in this embodiment of the invention specifically includes a pipeline conveying device comprising a first mounting frame 8 and a main pipe pusher 3 mounted on the first mounting frame 8. The main pipe pusher 3 is used to convey the long-distance pipeline 6 into the tunnel 5. The pipeline conveying device also includes a secondary pipe pusher 4 mounted on the first mounting frame 8. The secondary pipe pusher 4 and the main pipe pusher 3 are installed at intervals along the axial direction of the long-distance pipeline 6. The secondary pipe pusher 4 is used to restrict the long-distance pipeline 6 from moving along its axial direction.

[0041] When pipeline construction is required inside the tunnel, the first step is to use the pipe pusher 4 to hold the preceding single-section pipe 2 tightly to prevent it from moving along its axial direction. Then, the other single-section pipe 2 is hoisted onto the prefabricated pipe device. The prefabricated pipe device pre-sets the two single-section pipe 2 into a whole to form a long-distance pipeline 6. Then, the pipe pusher 4 releases the two sections, and the main pipe pusher 3 drives the prefabricated long-distance pipeline 6 to transport it into the tunnel 5, thereby completing the pipeline construction inside the tunnel.

[0042] The tunnel pipeline construction equipment provided in this embodiment of the invention specifically includes a prefabricated pipeline device comprising a second mounting frame 1 and a prefabrication mechanism mounted on the second mounting frame 1. The prefabrication mechanism is used to prefabricate single-section pipeline 2 into long-distance pipeline 6. The prefabrication mechanism includes an assembly assembly for assembling single-section pipeline 2, a fully automatic welding assembly for welding single-section pipeline 2, a mechanical anti-corrosion assembly for corrosion protection of the long-distance pipeline 6, and a non-destructive testing assembly for inspecting the long-distance pipeline 6.

[0043] In this embodiment, the backfill 7 on the outside of tunnel 5 forms a working platform, and the second mounting frame 1 is installed on the working platform. Since the prefabricated pipeline device itself is heavy and the pipeline is also heavy, the working platform formed by the backfill 7 can prevent the prefabricated pipeline device from settling and affecting the prefabrication of the long-distance pipeline 6.

[0044] The tunnel pipeline construction equipment provided in this embodiment of the invention further includes multiple guiding and conveying devices 9 installed at intervals along a preset direction within the tunnel 5. These multiple guiding and conveying devices 9 are used to transport the long-distance pipeline 6 along the preset direction. Because the long-distance pipeline 6 is relatively heavy, the multiple guiding and conveying devices 9 installed at intervals along the preset direction within the tunnel 5 allow the long-distance pipeline 6 to move on the guiding and conveying devices 9. The guiding and conveying devices 9 facilitate the transport of the long-distance pipeline 6. Simultaneously, the multiple guiding and conveying devices 9 installed at intervals along the preset direction allow the direction of transport of the long-distance pipeline 6 to be changed, thus enabling the long-distance pipeline 6 to be laid along the preset direction.

[0045] In this embodiment, please refer to the following for details. Figure 2 The guiding and conveying device 9 includes a third mounting frame 11 that can be fixedly installed inside the tunnel 5 and multiple sets of rollers 10 mounted on the third mounting frame 11. The guiding and conveying device 9 includes three sets of rollers 10 mounted on the third mounting frame 11, one set of rollers 10 being horizontally rotatably mounted on the third mounting frame 11, and the other two sets of rollers 10 being symmetrically tilted and rotatably mounted on the third mounting frame 11. The three sets of rollers 10 form a limiting groove that can restrict the movement of the long-distance pipeline 6 in directions other than its axial direction.

[0046] The third mounting bracket 11 is installed inside the tunnel 5 by anchor bolts 12. Three sets of rollers 10 are installed on the third mounting bracket 11, forming a limiting groove that restricts the long-distance pipeline 6 from moving in directions other than its axial direction, so that the long-distance pipeline 6 can only move along its axial direction. The rollers 10 are made of polyurethane material to avoid damaging the long-distance pipeline 6.

[0047] This invention provides a method for constructing pipelines inside tunnels to solve the problem of low efficiency in pipeline construction inside tunnels.

[0048] like Figure 1 As shown in the embodiment of the present invention, the method for constructing pipelines inside a tunnel includes the following steps:

[0049] S10: Prefabricate single-section pipelines into long-distance pipelines;

[0050] S20: Transporting long-distance pipelines into tunnels.

[0051] When pipeline construction is required inside the tunnel, the first step is to use the pipe pusher 4 to hold the preceding single-section pipe 2 tightly to prevent it from moving along its axial direction. The second single-section pipe 2 is then hoisted onto the prefabricated pipe assembly. The pairing assembly assembles the two pipes, followed by the fully automatic welding assembly welding the two pipe sections together. The mechanical anti-corrosion assembly performs anti-corrosion treatment on the welded long-distance pipeline 6. Finally, the non-destructive testing assembly inspects the long-distance pipeline 6, completing the prefabrication of the long-distance pipeline 6. Afterward, the pipe pusher 4 releases the prefabricated long-distance pipeline 6, and the main pipe pusher 3 drives the prefabricated long-distance pipeline 6 to be transported into the tunnel 5, thus completing the pipeline construction inside the tunnel.
