The subway tube sheet is mainly shield tube sheet, which is the main component of shield construction and the innermost barrier of the tunnel, which has the function of resisting soil layer pressure, groundwater pressure and some special loads. The shield tube sheet is the permanent lining structure of the shield tunnel. The quality of the shield tube sheet is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel.
The production of shielded subway segments strictly limits the appearance quality defects such as cracks, bubbles, color, slurry leakage, missing edges, and de-angles of the segment, which puts forward higher requirements for the quality of the segment release agent.
Subway segment release agent brand | segment release agent | subway segment release agent | oily release agent manufacturer.
According to the mold structure characteristics of the subway segment, the traditional mold release oil of emulsified concrete mold release agent was abandoned, and the proportion of concrete mold release agent was adjusted. Referring to the formula of fair-faced concrete mold release agent, the concrete mold release agent greatly improved the bubble coagulation effect. How to use the soil release agent, brush on the surface of the mold, and then use a clean towel soaked water-based environmentally friendly release agent to brush the surface of the mold twice, so that the concrete water-based release agent can be more evenly distributed in the mold of each area. It is also stable during vibration. After forming, the appearance and color difference of the segment also meet the customer's requirements. After steam maintenance, the appearance of the segment is not only free from process problems such as cracks and bubbles, but also does not affect the integrity of the product.
As an important part of the shield segment of the project, the release agent for concrete steel molds not only plays its own role to ensure the quality of customers' products, but also ends the suspicion of whether the release agent for cement is a hazardous waste. The production of environmentally friendly materials has no impact on the human body and the environment.
The difference between traditional water-based release agents on the market, what are the disadvantages of traditional water-soluble concrete release agents, mainly due to the vibration of the production of concrete products, resulting in water-based release agents affecting the stability of their own products or structural damage, such Cracks, bubbles, edges, corners, etc. As the main product of the subway segment release agent brand merchants, environmentally friendly water-based mold release agents have been paying attention to the information and consultation of shield segments for many years, keeping up with the changes of the times, constantly improving products, meeting the changing needs of the market, and adapting at any time. market.
The subway is fast and comfortable, occupies less land resources, has a large passenger volume, low energy consumption, low pollution and high safety performance. This mode of transportation has received more and more attention and is widely used in the construction of large and medium cities in my country. For a long time, domestic and foreign scholars and governments have always been highly valued by domestic and foreign scholars and governments. Today, subway traffic construction is being carried out in major cities across the country. Therefore, it is of great significance for theoretical research and practical guidance to explore the influence of urban subway on the market along the line.
