Description

Technical Field

[0002] In recent years, with the rapid development of urban rail transit systems, most underground sections of subways are constructed using the shield method, and some water pipelines are also constructed using the shield method. The shield method has very strict requirements on the quality of shield segments. The segment is the main assembly component of the shield construction and the innermost barrier of the tunnel. It is responsible for resisting soil pressure, groundwater pressure and some special loads. Reinforced concrete segments are commonly used products in tunnel engineering. When making segments, a casting device is required to cast the segments.

[0003] When pouring existing concrete segments, molds are usually used for pouring and forming. After pouring, in order to prevent air bubbles from remaining in the concrete, the concrete is squeezed by vibration to squeeze out the air inside the concrete. However, in actual use, the bubbles cannot be completely and stably emptied by squeezing. After the segment is poured, bubble cavities are likely to remain inside, affecting the production quality of the segment. In addition, it is not convenient to take and place the segment after pouring, which increases the difficulty of work and reduces work efficiency. For this reason, we propose a concrete segment pouring device to solve the above problems. Utility Model Content
