Introduction to the subway station wall in subway construction

With the continuous increase of the state's funds for subways in key cities, subways will be more and more valued by the government and citizens as postcards of cities, so the functions and cultural attributes of subways in the decoration stage will be higher. It plays an indispensable role in expanding the urban skeleton, improving urban transportation capacity, beautifying urban construction, and continuously driving urban economic development. The subway metro station wall is an important part of subway construction, let's see what it looks like!

Advantages of underground construction of subway station walls

The advantages of underground construction of subway metro station wall are first that the wall has high rigidity and good integrity; secondly, it is suitable for various geological conditions; it can also reduce the impact on the environment during the construction process, and it can also be constructed in reverse, which is conducive to speeding up the construction speed. Reduce project costs.

Joint Treatment of Underwater Concrete Pipeline for Retaining Wall

When the form of the retaining wall of the subway metro station wall is divided into the unit groove section, attention should be paid to the reasonable setting of the joint position between the groove sections. Joints should generally be avoided at corners and the connection between underground retaining walls and internal structures. Ensure that the underground diaphragm wall has good integrity. First, the joint part is provided between the uprights; secondly, the joint is arranged outside the connection with the internal structure. Again, the joints are set on the outside of the corners with integral steel cages; reinforcement cages; and finally, the circular and polygonal structures are attached to the interlocking pipe joints. Joints are generally made of steel and are mostly round. There are two construction sequences: one can be applied sequentially, and one can be applied in batches. When the first and second stages of jump excavation, the joint pipe diameter is generally 50mm smaller than the wall thickness (balance the water and soil pressure at both ends). The wall thickness of the pipe body is generally 19~20mm. The length of each section is generally 5~10m. When the height of the construction site is limited, the length of the pipeline can be appropriately shortened. Most of the joint pipes are circular, and there are also notched circles, wings, tenons, etc., most of which are circular, and their outer diameter is not less than 93% of the wall thickness. For easy pulling, butter the tube to keep it smooth. After 2 hours of pouring the concrete, make a half-turn.
