Description

Technical Field

[0001] This invention relates to a tunnel construction technology, and more particularly to an intelligent device and method for simultaneous tunnel excavation, joint cutting, and support construction. Background Technology

[0002] Roadways are various passages drilled between the surface and the ore body, used for ore transportation, ventilation, drainage, pedestrian access, and various necessary preparatory works for new mining operations for metallurgical equipment.

[0003] Current construction methods typically utilize tunneling machines (which rely on the rotating cutting head of the tunneling device to cut rocks with cutting teeth to achieve rock breaking and tunneling) for excavation, followed by drilling holes using anchor drilling rigs, and then using anchor bolts and anchor cables to support the excavated underground space to prevent the roof of the underground space from collapsing or the surrounding area from collapsing.

[0004] Because this construction method involves tunneling in a horizontal forward direction while drilling in a vertical upward direction, the tunneling and drilling directions are currently out of sync, meaning they are not coordinated. This prevents tunneling and support from proceeding in parallel, resulting in numerous construction steps, reduced construction progress, and difficulty in achieving intelligent control. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent equipment for simultaneous construction of tunnel excavation, slit cutting, and support. Compared with traditional tunneling and support methods, excavation and slit cutting do not interfere with each other, realizing simultaneous operation of excavation, slit cutting, and grouting support, thereby improving construction progress and facilitating intelligent tunneling. By cutting slits in the surrounding rock and injecting high-strength polymer materials, the strength of the surrounding rock is improved, achieving support for the tunnel surrounding rock, replacing the commonly used anchor-mesh-spraying technology. Through the injected polymer materials and the properties of the surrounding rock itself, a composite beam / composite arch structure is formed, improving construction efficiency.

[0006] To achieve the above objectives, the present invention provides an intelligent equipment for simultaneous construction of tunnel excavation, cutting, and support, comprising a traveling part, a main body part disposed on the traveling part, and an excavation part disposed on the main body part. The main body part is further provided with a cutting part and a support part in sequence, and the excavation part, the cutting part, and the support part are disposed on the main body part from front to back.

[0007] Preferably, the cutting section includes a plurality of cutting units evenly disposed on the top, sides and corners of the top and sides of the main body;

[0008] The support section includes multiple support units evenly distributed on the top, sides, and corners of the top and sides of the main body.

[0009] The multiple cutting units are arranged in a one-to-one correspondence with the multiple support units.

[0010] Preferably, the cutting unit includes a cutting support rod connected at one end to the main body and a cutting head rotatably connected to the other end of the cutting support rod. The cutting head is also connected to a cutting motor mounted on the cutting support rod.

[0011] Preferably, the cutting head is a cutting disc, which is arranged in a direction perpendicular to the inner wall of the tunnel.

[0012] Preferably, the support unit includes a material box disposed inside the main body, a grouting support rod with one end connected to the material box, and a grouting nozzle connected to the other end of the grouting support rod. The grouting nozzle faces the inner wall of the tunnel and is arranged parallel to the cutting disc.

[0013] The grouting support rod is equipped with a grouting pump.

[0014] Preferably, the material bin contains a polymer structural adhesive.

[0015] Preferably, the end of the cutting support rod near the main body and the end of the grouting support rod near the main body are both connected to the main body via reinforcing rods.

[0016] Preferably, the tunneling unit includes a tunneling telescopic support rod connected at one end to the main body and a blasting head disposed at the other end of the tunneling telescopic support rod. The blasting head is also connected to a tunneling motor disposed on the tunneling telescopic support rod.

[0017] The tunneling motor, the cutting motor, and the grouting pump are all electrically connected to the control unit located on the main body.

[0018] The method based on intelligent equipment for simultaneous construction of tunnel excavation and joint cutting support includes the following steps:

[0019] S1. Turn on the construction equipment. First, the traveling unit drives the construction equipment to the initial position, then the traveling unit closes. Then the tunneling unit starts working. The blasting head of the tunneling unit rotates under the drive of the tunneling motor, and works with the tunneling telescopic rod to excavate the tunnel until a square tunnel is formed.

[0020] S2. Then the traveling unit is opened, which drives the construction equipment to enter the next section of the square tunnel for excavation. At the same time, the cutting unit is opened, and multiple cutting discs of the cutting unit are simultaneously cut into the square tunnel section under the action of the cutting motor, thus completing the cutting of the inner wall of the square tunnel section.

[0021] S3. While the traveling part continues to travel and the tunneling part is tunneling and the cutting part is cutting, when the grouting nozzle of the grouting part is aligned with the cut formed in step S2, the grouting part is opened, and the grouting nozzle sprays high-molecular structural adhesive into the corresponding cut under the action of the grouting pump to form a support body, thereby realizing the simultaneous progress of tunneling, cutting and support.

[0022] Therefore, the intelligent equipment for simultaneous construction of tunnel excavation, joint cutting, and support using the above-mentioned structure in this invention does not interfere with each other between excavation and joint cutting, and realizes simultaneous operation of excavation, joint cutting, and grouting support, thereby improving the construction progress.

A cutting part 4 and a support part 3 are also disposed on the body part 2 in sequence. The tunneling part 5, the cutting part 4 and the support part 3 are disposed on the body part 2 from front to back. The walking part 1 is a tracked walking mechanism. Since the structural principles of the walking part 1 and the body part 2 are common knowledge in the art, they will not be described in detail here.

[0030] Preferably, the cutting section 4 includes multiple cutting units evenly distributed on the top, sides and corners of the top and sides of the main body 2; the support section 3 includes multiple support units evenly distributed on the top, sides and corners of the top and sides of the main body 2; the multiple cutting units and the multiple support units are arranged in a one-to-one correspondence.

[0031] Preferably, the cutting unit includes a cutting support rod 41 connected at one end to the main body 2 and a cutting head 40 rotatably connected to the other end of the cutting support rod 41. The cutting head 40 is also connected to a cutting motor mounted on the cutting support rod 41. Preferably, the cutting head 40 is a cutting disc, which is arranged in a direction perpendicular to the inner wall of the tunnel 8.

[0032] Preferably, the support unit includes a material box disposed inside the main body 2, a grouting support rod 31 with one end connected to the material box, and a grouting nozzle 30 connected to the other end of the grouting support rod 31. The grouting nozzle 30 faces the inner wall of the tunnel 8 and is arranged parallel to the cutting disc. A grouting pump is disposed inside the grouting support rod 31. Preferably, the material box contains polymer structural adhesive.

[0033] Preferably, the end of the cutting support rod 41 near the body part 2 and the end of the grouting support rod 31 near the body part 2 are both connected to the body part 2 via reinforcing rods, resulting in higher connection reliability.

[0034] Preferably, the tunneling section 5 includes a tunneling telescopic support rod 51 connected to the main body section 2 at one end and a blasting head 50 disposed at the other end of the tunneling telescopic support rod 51. The blasting head 50 is also connected to a tunneling motor disposed on the tunneling telescopic support rod 51. Since the structure of the tunneling telescopic support rod 51 and its connection method with the main body section 2 are common knowledge in the art, they will not be described in detail here. The tunneling motor, the cutting motor and the grouting pump are all electrically connected to the control section 6 disposed on the main body section 2. Moreover, the electronic components in this embodiment are all mature products on the market. This application only needs to purchase them and connect them according to the instructions without making any improvements. Therefore, they will not be described in detail here.

[0035] The method based on the equipment for simultaneous construction of tunnel excavation, cutting, and support in roadway 8 includes the following steps:

[0036] S1. Turn on the construction equipment. First, the traveling part 1 drives the construction equipment to the initial position and then the traveling part 1 is closed. Then the tunneling part 5 starts to work. The blasting head 50 of the tunneling part 5 rotates under the drive of the tunneling motor and cooperates with the tunneling telescopic rod to tunnel the roadway 8 until a square roadway 8 is formed.

[0037] S2. Then, the traveling part 1 is opened, and the traveling part 1 drives the construction equipment to enter the next section of square tunnel 8 for excavation. At the same time, the cutting part 4 is opened, and the multiple cutting discs of the cutting part 4 are simultaneously cut into the square tunnel 8 under the action of the cutting motor, thus completing the cutting of the inner wall of the square tunnel 8.

[0038] S3. While the traveling part 1 continues to travel on the tunneling part 5 for tunneling and the cutting part 4 for cutting, when the grouting nozzle 30 of the grouting part is aligned with the cut 7 formed in step S2, the grouting part is opened, and the grouting nozzle 30 sprays high molecular structural adhesive into the corresponding cut 7 under the action of the grouting pump to form the support body 9, thereby realizing the simultaneous progress of tunneling, cutting 7 and support.

[0039] It should be noted that, since the tunneling speed is relatively slow, while the cutting speed 7 and grouting speed are relatively fast, the tunneling work in this embodiment is a non-stop operation, while the cutting speed 7 and grouting are intermittent operations. Moreover, the cutting speed 7 and grouting work of this section of the tunnel 8 can be completed before the next section of the tunnel 8 is tunneled.

[0040] Therefore, the intelligent equipment for simultaneous construction of tunnel excavation, joint cutting, and support using the above-mentioned structure in this invention does not interfere with each other between excavation and joint cutting, and realizes simultaneous operation of excavation, joint cutting, and grouting support, thereby improving the construction progress.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
