Description

Technical Field

[0001] The utility model relates to the technical field of shield tunnel construction, in particular to a segment assembly and a segment lining device. Background Technique

[0002] At present, the shield tunnel / tunnel segment filled with gravel refers to filling gravel behind or in the gap of the segment during the construction of the shield tunnel / tunnel to enhance the support effect and stability of the tunnel; this method has its advantages under specific construction conditions, but there are also some significant drawbacks.

[0003] Now, there are the following problems in the process of filling gravel in the shield tunnel / tunnel segment: 1) Using the traditional method of blowing gravel will cause uneven distribution of gravel, resulting in a slope phenomenon where some spaces have no gravel distribution; this will cause a certain point of the segment to be subjected to the concentrated load of the surrounding rock, thus causing the deformation of the segment; 2) The uneven distribution of gravel may not be able to provide uniform supporting force, resulting in uneven settlement or deformation of the shield segment during operation, affecting the structural safety and service life of the tunnel. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is how to ensure the uniform and dense filling of gravel.

[0005] The utility model realizes the solution of the above technical problems through the following technical means:

[0007] Beneficial Effect: Through the setting of the filling bag and its material, after filling gravel, it can ensure that the filling bag is in close contact with the surrounding rock and the segment, so that the segment is subjected to a uniform distributed load, and avoid the segment from being deformed due to concentrated load when the gravel is unevenly distributed.

[0008] Further, the segment (21) is arranged in an arc section.

[0009] Further, the segment (21) is arranged in a semi-circular section.

[0010] Further, a filling hole (22) is penetrated and opened in the middle of the segment (21).

[0011] Further, the filling bag (23) is made of polyurethane.

[0012] Further, the filling bag (23) is made of polycarbonate.

[0013] Further, a plurality of holes are provided in the filling bag (23).

[0014] Beneficial effects: Through the arrangement of the holes, gas escape can be ensured.

[0015] The present utility model also discloses a segment lining device including the segment assembly according to any one of the above technical solutions, further including a surrounding rock (1). A plurality of segment assemblies are provided in the surrounding rock (1), and the plurality of segment assemblies are arranged in a circular pattern within the surrounding rock (1).

[0016] Beneficial effects: Through the arrangement of a plurality of segment assemblies, it is possible to ensure that each segment is subjected to a uniformly distributed load, avoiding deformation of the segments.

[0017] Further, six segment assemblies are provided.

[0018] Further, gravel (3) is provided in the filling bag (23). Description of the Drawings

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0022] Embodiment 1

[0023] As Figure 1 shown, this embodiment provides a segment lining device, including a surrounding rock 1, segment assemblies 2, and gravel 3.

[0024] As Figure 1 shown, a plurality of segment assemblies 2 are provided in the surrounding rock 1, and the plurality of segment assemblies 2 are arranged in a circular pattern within the surrounding rock 1. In this embodiment, six segment assemblies 2 are arranged in a circular pattern within the surrounding rock 1; gravel 3 is provided within the segment assemblies 2.

[0025] As Figure 1 , Figure 2As shown in the figure, the segment assembly 2 includes segments 21, filling holes 22, and filling bags 23. The segments 21 are arranged in an arc or semi-circular shape. Filling holes 22 are drilled through the segments 21. In this embodiment, the filling holes 22 are drilled through the middle of the segments 21. A filling bag 23 is arranged around the segments 21, and the filling bag 23 is communicated with the filling holes 22. The filling bag 23 is made of a soft material. In this embodiment, the filling bag 23 is made of polyurethane or polycarbonate. There are holes with a diameter smaller than that of gravel on the filling bag 23 to ensure the escape of gas.
