[0026] During tunnel construction, cave-in accidents are likely to occur, causing property and personal casualties and seriously affecting the stability and harmony of project construction. Therefore, it is necessary to set up a tunnel escape pipeline at the construction site during construction to ensure the safety of tunnel and underground engineering construction. Currently, the mainstream method in China is to lay an escape pipeline in the tunnel as an escape passage for construction workers. The escape pipeline can effectively resist the impact of falling rocks during a tunnel cave-in accident, isolate dust and water in the tunnel, and at the same time provide survival resources such as air, water, and light sources for construction workers, effectively improving the survival rate of construction workers and reducing the loss of casualties.

[0027] The existing escape pipelines are usually composed of multiple pipe bodies inserted into each other or connected through flange plates. During the implementation process at the construction site, the layout of the escape pipelines connected by insertion and flange plates is relatively cumbersome and inconvenient to install, seriously affecting the progress of on-site construction.

[0028] Please refer to Figure 1, the present utility model provides an escape pipe 100, which includes a plurality of pipe bodies 1 and a flexible connection structure; an escape passage is formed inside the pipe body 1, and the plurality of pipe bodies 1 are arranged in sequence along their axial directions, and the ends of two adjacent pipe bodies 1 are arranged at intervals; the flexible connection structure is arranged between the ends of two adjacent pipe bodies 1 for connecting the ends of two adjacent pipe bodies 1.

[0029] The present utility model provides an escape pipe 100, which includes a plurality of pipe bodies 1. An escape passage is formed inside the pipe body 1 for people to escape and walk. The plurality of pipe bodies 1 are arranged at intervals in sequence along the axial direction. Among them, two adjacent pipe bodies 1 are connected to each other through a flexible connection structure, so that a flexible connection is formed between the two pipe bodies 1, which is convenient for splicing between the pipe bodies 1 without the need for hard connection, effectively avoiding the problems of difficult layout and heaviness of the escape pipe during the construction of the bench method. The construction process is simple, improving the safety and efficiency of tunnel construction, ensuring the safety of construction operations and the convenience of the layout of the escape pipe, and having obvious economic benefits.

[0030] It should be noted that during the use of the pipe body 1, when an accident occurs and escape is needed, it will withstand external impacts and torques, etc. Therefore, in order to ensure the safe use of the pipe body 1, the pipe body 1 is a high-strength steel pipe. Among them, the structural strength of the high-strength steel pipe meets the requirements for anti-impact, anti-corrosion, etc. of the pipe in the escape requirements, and different structural strengths are set for different scenarios, which are not specifically limited here.

[0031] It should be noted that the flexible connection structure is used to connect two adjacent pipe bodies 1. As long as the flexible connection structure can achieve flexible connection. Since the underground construction environment is harsh, when using rigid parts for connection, the construction accuracy needs to be ensured to ensure that the rigid parts correctly connect two pipes. Among them, there are various setting methods for the flexible connection structure. For example, flexible connectors such as connecting steel cables are used to pull and splice the two pipes.

[0032] To ensure the safety of the connection between the pipeline bodies 1, in this embodiment, the flexible connection structure includes a protective net 2, and both ends of the protective net 2 are respectively connected to the ends of two adjacent pipeline bodies. In this embodiment, the flexible connection structure includes the protective net 2, and the gap between the two pipeline bodies 1 is shielded by the protective net 2 to prevent foreign objects such as falling rocks from hitting the connection between the two pipeline bodies 1, and to avoid danger when personnel cross the connection of the pipeline bodies 1. At the same time, by connecting the pipeline bodies 1 in the way of the protective net 2, the connection tension between the pipelines can be evenly distributed on the net, which can improve the structural strength of the flexible connection structure.

[0033] In an embodiment provided by the present utility model, there are multiple pieces of the protective net 2, and the multiple pieces of the protective net 2 are arranged in sequence along the circumferential direction of the pipeline body 1 to cover the gap between the ends of two adjacent pipeline bodies 1. In this embodiment, the multiple pieces of the protective net 2 are arranged in sequence along the circumferential direction of the pipeline body 1, so that the multiple protective nets 2 can protect around the gap of the pipeline body 1, protect the gap from the circumferential direction, avoid the limitation of the protection angle caused by a single protective net, and improve the protection effect of the flexible connection structure.

[0034] In another embodiment provided by the present utility model, there are multiple pieces of the protective net 2, and the multiple pieces of the protective net 2 are arranged in layers along the radial direction of the pipeline body 1. In this embodiment, through the multiple pieces of protective nets 2 arranged in layers, the structural strength of the flexible connection structure can be improved, and the problem of the single protection being broken and the protection failing when being impacted can be avoided.

[0035] It should be noted that in the circumferential arrangement and layered arrangement of the above-mentioned protective net 2, either one can exist, or both can exist at the same time, and they are selected according to different escape environments. In the present utility model, the protection effect is the best when both exist at the same time, and it can be applied to various environments.

[0036] On the other hand, the protective net 2 is a high-strength flexible steel wire net. In this way, the protection effect of the protective net 2 can be improved, and the protective net 2 can be prevented from breaking.

[0037] It should be noted that the high-strength flexible steel wire net is a common term in the construction field. Among them, the high-strength flexible steel wire net only needs to meet certain safety standards such as impact resistance standards and stress standards, and no specific model is limited here.

[0038] On the other hand, there are various ways to connect the protective net 2 to the pipeline body 1, such as welding, passing through the hole grooves outside the pipeline body 1, etc. As long as the protective net 2 can be connected to the pipeline body 1.

[0039] It should be noted that the protective net 2 can be directly connected to the pipe body 1, or can be connected to the pipe body 1 through an adapter. In this embodiment, an installation steel ring 3 is sleeved on the outer side wall of the end of the pipe body 1, and the end of the protective net 2 is connected to the installation steel ring 3. In this embodiment, the installation steel ring 3 is sleeved on the pipe body 1 to install the protective net 2, avoiding the protective net being directly connected point-to-point to the pipe body 1, resulting in stress concentration points on the pipe body 1 and reducing the structural strength of the pipe body 1. Through the installation steel ring 3, under the condition of ensuring the structural strength of the pipe body 1, it is convenient to install the protective net 2.

[0040] Among them, the installation steel ring 3 can be fixedly arranged on the pipe body 1. For example, it can be directly fixed by welding or other means.

[0041] In this embodiment, the installation steel ring 3 is rotatably sleeved on the end of the pipe body 1. So that the protective net 2 can rotate relative to the escape pipe steel pipe, which is convenient for position adjustment. At the same time, it can also move a certain position when suffering an impact to buffer the impact force. In addition, since the installation steel ring 3 is rotatably sleeved on the end of the pipe body 1, when installing the protective net 2, it is not necessary to ensure the fine alignment between the two pipe bodies 1. The protective net 2 can be installed by adjusting the position of the installation steel ring 3, which is convenient for the installation of the protective net 2.

[0042] Among them, the installation steel ring 3 is rotatably sleeved on the end of the pipe body 1. In order to prevent the installation steel ring 3 from falling off, it is necessary to limit the position of the installation steel ring 3, such as by means of a limit block.

[0043] Furthermore, in this embodiment, an installation groove is recessed on the outer side wall of the end of the pipe body 1, and the installation steel ring 3 is rotatably sleeved in the installation groove. The position of the installation steel ring 3 is restricted through the installation groove to prevent position deviation.

[0044] In addition, in another embodiment provided by the present utility model, a limit block is protruded on the outer side wall of the end of the pipe body 1. The installation steel ring 3 is sleeved on the outer side wall of the end of the pipe body 1, and the limit block is on one side of the installation steel ring 3 facing the end of the pipe body 1. In this way, the position adjustment of the installation steel ring 3 in the length direction can also be realized.

[0045] On the other hand, there are multiple ways to connect the end of the protective net 2 to the installation steel ring 3. For example, it can be directly welded to the installation steel ring 3 by welding, or can be connected to the installation steel ring 3 through a connector.

[0046] In this embodiment, mounting lugs 31 are formed on the outer sidewall of the mounting steel ring 3; a locking member 21 is provided at the end of the protective net 2, and the locking member 21 is snap-fitted onto the mounting lug 31. In this embodiment, the protective net 2 is installed by means of the locking member 21, which facilitates the quick disassembly and assembly of the protective net 2. At the same time, it avoids damage to the structures of the protective net 2 and the mounting steel ring 3, and is convenient for recycling.

[0047] It should be noted that the locking member 21 is a metal lock, and the mounting lug 31 and the protective net 2 are connected by means of buckling.

[0048] Furthermore, the mounting lug 31 and the locking member 21 form a connection group, and a plurality of such connection groups are provided, and the plurality of connection groups are arranged at intervals. This is to improve the connection structural strength between the protective net 2 and the mounting steel ring 3.

[0049] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
