[Column] Drainage and Non-Drainage Expansion Devices

Explanation of the differences and devices for enhancement! I have also summarized the mechanisms for enhancing the functions of the devices.

The expansion and contraction devices can be broadly divided into drainage type and non-drainage type. When these devices first started being installed, the drainage type was used, but over time, the non-drainage type has become the mainstream. The difference between the two lies in whether or not water leakage measures are implemented. However, due to the infrastructure development policies set by the government, most manufacturers have started producing non-drainage types. This article introduces the differences between drainage and non-drainage types as well as their usage ratios. Additionally, we have summarized the mechanisms that enhance the functions of the devices, so please refer to that as well. *For detailed content of the column, you can view it through the related links.

Nagoya Expressway Exclusive Expansion Device "Hybrid Joint NCS-40"

Compliant with the standards for urban expressways. Nagoya Expressway exclusive specifications for bridge expansion devices "Hybrid Joint NCS-40."

This product is a specially designed expansion joint developed to meet the conditions of the Nagoya Expressway. Urban expressways, such as the Metropolitan Expressway and Hanshin Expressway, have different design conditions and quality standards for each highway. Therefore, Crittec Industries consistently responds to the development, manufacturing, and construction of expansion joints in accordance with each standard. In urban expressways, lightweight and slim designs are often adopted, leading to the use of steel deck bridges. In typical bridges, there is a thick concrete deck beneath the pavement, while in steel deck bridges, the area directly beneath the pavement consists of steel materials. On the other hand, steel deck bridges exhibit significant expansion and contraction behavior due to temperature changes and traffic, necessitating high followability and durability at the joint sections. Additionally, when installing joints, it is essential to meet complex performance criteria, such as "a shape that fits within the pavement," "high resistance to strain and vibration," and "a structure that can be securely fixed to the steel deck." The "Hybrid Joint NCS-40" has passed the fatigue load test (durability of over 15 years) set by the Nagoya Expressway Public Corporation, and the improvements made to various technologies have led to its adoption. Currently, this product is in the process of being registered as a "new technology" certified by the same corporation. *Please feel free to contact us for inquiries.
