This section introduces: “ANB flexible joint”, which is used at the joint section of box culvert into which rain water from main highway is flow in; “balloon rubber”, the injection part which inject epoxy resin for repair work for cracking on the building; and “expansion joint”, which is used at the joints of the bridges. Besides, in addition to the introduction of “AN joint series“, the flexible joints for sewer work, such working method is described in detail.

■ Features and benefits
As a major feature of the AN Joint Series products, the use of water-swelling sponge, which has been uniquely developed by Nishikawa, can be pointed.

■ Features and benefits
This is an earthquake-proof joint purported to prevent the damage to the joint section of box culvert, which is laid underground and to maintain the performance and function to allow ground water to flow smoothly. This joint also provides reliable earthquake-proof performance by making the profile product in ìW" shape with expandable design. |

■ Features and benefits
This is an epoxy resin injection kit for the repair work of cracking in the building. By making use of internal pressure from the shrinking characteristics of rubber, the system materialized low-pressure and low-rate injection process which is the most suitable epoxy resin injection work. |

■ Features and benefits
This is a butt expansion joint made in combination with rubber and parallel steel sheets for the special use in small span arrangement. By providing the network structure in the design, the joint can absorb any shrinkage of bridge construction resulting from the difference in temperature between summer and winter. |
