Description

Technical Field

[0001] The utility model relates to the technical field of tunnel lining, in particular to a high-altitude cold tunnel lining device. Background Art

[0002] Tunnel engineering, especially in high-altitude and cold regions, faces numerous technical challenges. Tunnel lining, as a crucial component of the tunnel structure, has a quality that is directly related to the safety and durability of the tunnel. The steel reinforcement within the tunnel lining is a key element in supporting and strengthening the lining structure. Its positioning accuracy and flexibility have a crucial impact on the overall performance of the tunnel.

[0003] In traditional tunnel construction, rebar positioning is often performed using fixed devices. While this approach ensures installation efficiency to a certain extent, it lacks adaptability in the complex and ever-changing tunnel environment (such as large temperature fluctuations and complex geological conditions), especially in high-altitude and cold regions where material properties fluctuate due to temperature changes. Specifically, once rebar positioning is completed, it is difficult to adjust the rebar spacing according to actual site conditions to meet the precise requirements of the tunnel lining design or to respond to unexpected situations during construction, which in turn affects the overall quality and safety of the tunnel structure. Therefore, we have proposed a lining device for high-altitude and cold-zone tunnels to improve this. Summary of the Invention

[0028] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0029] As described in the background art, in traditional tunnel construction, steel bar positioning is mostly carried out by installing fixed devices. Although this method guarantees installation efficiency to a certain extent, faced with the complex and changeable tunnel environment (such as large temperature fluctuations, complex geological conditions, etc.), especially the changes in material properties caused by temperature changes in high-altitude and cold areas, the fixed devices appear to have insufficient adaptability. Specifically, once the steel bar positioning is completed, it is difficult to adjust the steel bar spacing according to the actual situation on site to adapt to the precise requirements of the tunnel lining design or to respond to emergencies during the construction process, which in turn affects the overall quality and safety of the tunnel structure.

[0030] In order to solve this technical problem, the utility model provides a high-altitude and cold tunnel lining device.

[0031] Specifically, please refer to Figure 1-Figure 3 The high-altitude tunnel lining device specifically includes:

[0032] The support frame 1 has a plurality of sliding sleeves 2 on its outer surface, a steel bar clamp 201 is fixedly connected to the sliding sleeve 2, and a connecting piece is provided between the sliding sleeve 2 and the support frame 1.

[0033] The utility model provides a high-altitude tunnel lining device. The present application provides a sliding sleeve 2, which is arranged on the outer surface of the support frame 1 and can move along the trajectory of the support frame 1, so that the position of the steel bar clamp 201 can be adjusted, so that after the steel bar is inserted into the steel bar clamp 201, it can be adjusted according to the actual needs of the tunnel lining, thereby improving the flexibility and adaptability during the construction process.

[0034] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0037] Example 1, please refer to Figure 1-Figure 3 A high-altitude tunnel lining device includes a support frame 1, the outer surface of the support frame 1 is provided with a plurality of sliding sleeves 2, the sliding sleeves 2 are fixedly connected to the steel bar clamping rings 201, and a connecting piece is provided between the sliding sleeves 2 and the support frame 1; the present application provides the sliding sleeves 2, which are provided on the outer surface of the support frame 1 and can move along the trajectory of the support frame 1, so that the position of the steel bar clamping rings 201 can be adjusted, so that after the steel bars are inserted into the steel bar clamping rings 201, they can be adjusted according to the actual needs of the tunnel lining, thereby improving the flexibility and adaptability during the construction process.

[0038] Further, such as Figure 3 As shown, the side of the steel bar clamp 201 away from the sliding sleeve 2 is set as an opening, and slopes are set on both sides of the opening. The opening is used to connect and separate the steel bar and the steel bar clamp 201, and the slope is set to facilitate the insertion of the steel bar into the steel bar clamp 201 from the opening.

[0039] Further, such as Figure 1-Figure 3 As shown, a number of positioning holes 101 are provided on the support frame 1, and the connecting piece is a hand-tightening bolt 202 threadedly connected to the sleeve 2, and the end of the hand-tightening bolt 202 is plugged into the positioning hole 101. The position of the sleeve 2 can be fixed through the connection between the hand-tightening bolt 202 and the positioning hole 101.

[0040] Example 2 further optimizes the high-altitude cold tunnel lining device provided in Example 1. Specifically, Figure 1-Figure 3 As shown, a support frame 4 is provided inside the support frame 1 , and a plurality of hydraulic cylinders 3 are connected between the support frame 4 and the support frame 1 .

[0041] Further, such as Figure 2 As shown, the sleeve 2 is provided with an escape opening 203, the position of which corresponds to the position of the hydraulic cylinder 3. The setting of the escape opening 203 enables the sleeve 2 to avoid the hydraulic cylinder 3, thus preventing the hydraulic cylinder 3 from affecting the movement of the sleeve 2.

[0042] Further, such as Figure 1-Figure 3 As shown, the support frame 1 is composed of a plurality of arc-shaped support plates 102 , and gaps are left between the plurality of arc-shaped support plates 102 so that the support frame 1 can be contracted or expanded. After contraction, the support frame 1 can be conveniently placed in or taken out of the tunnel.

[0045] Further, such as Figure 1 As shown, the piston rod of the hydraulic cylinder 3 is connected to the arc-shaped support plate 102 .

[0046] Furthermore, the support frame 4 is used to support the hydraulic cylinder 3 , and the hydraulic cylinder 3 is used to drive the arc-shaped support plate 102 to move. The hydraulic cylinder 3 drives the arc-shaped support plate 102 to move, so that the support frame 1 can be retracted.

[0047] The use process of the high-altitude cold tunnel lining device provided by the utility model is as follows:

[0048] After the present application is placed in the tunnel, the hydraulic cylinder 3 pushes the arc-shaped support plate 102 away from the support frame 4, and then the steel bar is inserted into the steel bar clamping ring 201. When the position of the steel bar needs to be adjusted, the hand-tightening bolt 202 is loosened to separate the hand-tightening bolt 202 from the positioning hole 101, and then the sliding sleeve 2 is pushed to move to adjust the position of the sliding sleeve 2, and then the spacing of the steel bars is adjusted. After adjustment, the hand-tightening bolt 202 is tightened so that the hand-tightening bolt 202 is inserted into the corresponding positioning hole 101.
