Description

[0002] In modern urban construction, shield construction has become the preferred construction method for subway tunnel projects due to its many advantages such as fast construction speed, high lining quality, and low impact on the surrounding environment. The core of this method is to use precast concrete shield segments as the main structural unit of the tunnel lining. The construction quality of these segments is directly related to the safety, stability and long-term service life of the entire subway tunnel project.

[0003] However, in the actual production process of shield segments, a common problem is that a large number of bubbles often form on the surface of the segments. These bubbles not only seriously affect the aesthetics of the segments, but more importantly, they reduce the mechanical properties and impermeability of the segments, making it difficult for the segments to meet the strict requirements of subway tunnel engineering on material strength and durability. In addition, the presence of bubbles will also lead to more surface defects on the segments, easily forming stress concentration areas, thereby further weakening their overall strength and durability.

[0016] As described above, the present invention has the following beneficial effects: 1. During the forming process of tube-shaped concrete, since the inner and outer surfaces of the tube-shaped concrete occupy a large surface area, these surfaces are prone to defects, especially bubble defects. The test device has a high flexibility through the detachable first enclosure, the second enclosure and the third enclosure, and the first fastening module and the second fastening module matched therewith. This design facilitates the rapid adjustment or replacement of the enclosure according to the test requirements, and also facilitates cleaning and maintenance. By installing the first detection device and the second detection device, the inner and outer surfaces of the tube segment after forming are monitored respectively, and the influence of the mold roughness on the bubbles formed by the concrete tube segment can be comprehensively and accurately evaluated. This dual detection mechanism helps to improve the accuracy and reliability of the test.

At the same time, since the device has high repeatability and accuracy, it can also provide strong technical support for the production of concrete tube segments.

[0017] 2. When the tube-shaped concrete is formed, the tube-shaped concrete has a bending radius, and the radii on the inside and outside are different. In order to study the influence of the roughness of the inner mold and the roughness of the outer mold on the forming effect. In this application, different roughness can be used according to the experimental requirements through the detachable first and second enclosures. Researchers can easily adjust the composition of the mold, and then systematically study the influence of different mold roughness on bubbles in the forming process of concrete tube segments. In actual operation, researchers can select enclosures with specific roughness for combination according to the purpose of the experiment, so as to create a mold environment with different surface characteristics. In this way, researchers can more intuitively observe the forming effect of concrete tube segments under different roughness conditions, especially the distribution and morphological changes of bubbles. It helps to deeply understand the formation mechanism of bubbles in the forming process of concrete tube segments, and can also provide a strong experimental basis for optimizing mold design and improving the quality of concrete tube segments.

When pouring concrete, concrete will also flow through the anti-tilt grooves and be connected to the pouring space of the pipe segment. In this way, after the concrete solidifies, a protrusion will be formed at the position of the anti-tilt groove.
