Description

Technical Field

[0002] At present, during the construction of double-track tunnel inverts, after the formwork is removed, due to the low strength of the concrete, subsequent mechanical equipment passing through the invert filling surface is prone to damage to the corners of the central ditch and is difficult to repair. In some sections, steel plates may be laid on the upper part of the central ditch to facilitate passage and protect the corners, but frequent dragging of the steel plates will also cause damage to the corners of the central ditch. In order to meet the current high standards and strict requirements of tunnel construction, it is necessary to protect the corners of the central ditch to avoid damage that affects the secondary construction of the central ditch. The current conventional practice in tunnel construction is to simply set up warning columns on the invert filling surface on both sides of the central ditch, which can only serve as a simple warning, and cannot provide a good protection for the central ditch, let alone meet the increasingly high standardization requirements of tunnel construction.

[0025] First Exemplary Embodiment

[0026] This exemplary embodiment provides a central gutter corner protection device.

[0027] Figure 1 A schematic diagram showing the overall structure of a central ditch corner protection device of an exemplary embodiment of the utility model is shown; Figure 2 The schematic cross-sectional view of the structure of the central water ditch corner protection device of an exemplary embodiment of the utility model is shown below. Figures 1-2 To describe the center gutter corner protection device of this exemplary embodiment.

[0028] In this exemplary embodiment, Figure 1 or Figure 2 As shown in the figure, the central ditch edge protection device mainly includes a protection mechanism and a cross brace 2. The protection mechanism may include two L-shaped steel plates 1. The L-shaped steel plates are arranged along the length direction of the central ditch. The two L-shaped steel plates are parallel to each other. They are arranged above the two sides of the central ditch to protect the edges of the two sides of the central ditch at the same time. Figure 1 As shown in the figure, the cross brace 2 is arranged between the two L-shaped steel plates and is arranged at intervals along the length direction of the L-shaped steel plates. The two L-shaped steel plates 1 are protected from falling into the ditch. The device can directly protect the edges and corners of the central ditch and is easy and quick to install.

[0029] In this exemplary embodiment, Figure 2As shown in , the L-shaped steel plate may include a transverse steel plate 12 and a vertical steel plate 11, and one side of the transverse steel plate 12 is vertically connected to the vertical steel plate 11. The angles of the two L-shaped steel plates are in opposite directions. In addition, the length and width of the transverse steel plate and the vertical steel plate can be adjusted and designed according to the structural dimensions of the central ditch to ensure that the central ditch corner protection device will not easily fall into the ditch or other installation failures will occur due to incompatibility with the central ditch dimensions. In addition, the structural dimensions of the transverse steel plate and the vertical steel plate can be designed in advance, and the transverse steel plates and the vertical steel plates with the designed structural dimensions can be centrally processed in a steel bar processing plant. The processed L-shaped steel plates have uniform dimensions. Compared with randomly processed protection devices, it has the characteristics of linear straightness and smooth surface after installation. It has become a construction highlight in a tunnel with relatively messy construction, which meets the current standardization requirements of tunnel construction.

[0030] In this exemplary embodiment, the spacing distance between the cross braces may be 1-3 m, for example, 1.4 m, 2.6 m or 2.9 m.

[0031] In this exemplary embodiment, both ends of the cross brace can be fixedly connected to the adjacent L-shaped steel plates. For example, welding connection. When installing the central ditch of a double-track tunnel, it is only necessary to simply fix the central ditch corner protection device on the edges of both sides of the central ditch. The installation and disassembly are simple and efficient. During the on-site installation process, the installation length of the central ditch corner protection device can accumulate to thousands of meters. And after installation, there is no need for frequent disassembly and transportation, and it can be directly dragged on the ditch. The structure is stable and is not affected by other construction.

[0032] In this exemplary embodiment, Figure 1 As shown in the figure, a plurality of vertical steel pipes 3 can be arranged at intervals on the upper part of the horizontal steel plate in the L-shaped steel plate along the length direction of the central ditch. Here, a finished warning column can be mounted on the vertical steel pipe. The vertical steel pipe can also be used directly as a warning column. Of course, the utility model is not limited to this, as long as it can achieve a warning function. The vertical steel pipe can not only play a warning role, but also play a role in edge protection during construction and operation.

[0033] In this exemplary embodiment, the intervals between the vertical steel pipes may be 1 to 3 m, for example, 1.4 m, 2.6 m, or 2.9 m.

[0034] In this exemplary embodiment, Figure 1 or Figure 2 As shown in the figure, the width between the two L-shaped steel plates can be equal to the width of the central ditch. During the hoisting and transportation of the central ditch corner protection device, the overall orientation of the device may rotate in mid-air. The width between the two sides of the protection mechanism can be equal to the width of the central ditch to ensure that it will not fall to the bottom of the ditch during the hoisting and transportation process.

[0035] In this exemplary embodiment, the bottom of the central ditch corner protection device can be higher than the bottom of the central ditch, so that the corners of the central ditch can be protected during construction to avoid damage that affects the construction quality and progress.

[0036] In this exemplary embodiment, the central ditch corner protection device can be made of high-strength steel, such as Q235. It is not easy to be damaged during construction. During the tunnel invert construction process, the protection device can be dragged to the front for cyclic installation and use, which is conducive to saving construction costs while achieving central ditch corner protection.

[0039] The central gutter corner protection system includes a plurality of interconnected central gutter corner protection devices as described in the first exemplary embodiment.

[0040] In this exemplary embodiment, there is no need to install connectors between the central ditch corner protection devices in the central ditch corner protection system, and they can be simply spliced ​​and assembled together. The operation is simple and easy to implement. It does not affect the progress of the main construction. In addition, according to the progress of the tunnel central ditch construction, the protection system can be installed in the central ditch section where the central ditch corner protection system is not laid in a timely manner to ensure the timeliness, circulation and continuity of the central ditch corner protection system.

[0041] In summary, the advantages of the present invention may include at least one of the following:

[0042] (1) The protection device provided by the utility model can timely install the protection device on the central ditch section where the steel plate is not laid according to the progress of the construction of the central ditch of the tunnel, so as to ensure the timely, cyclic and continuous protection device of the corners of the central ditch;
