More particularly, the present invention relates to an expansion joint which is capable of preventing an open water path from being broken due to this action when the open water path shrinks or expands according to the surrounding environment, The present invention relates to an expansion joint device for a can opener equipped with a fiber reinforcing material which is easy to install and a construction method for an expansion joint device for a can opener.

In addition to the project to sort out the agricultural infrastructure such as agricultural water development, land consolidation and drainage improvement, the Gagar aqueduct that is made of ordinary reinforced concrete has been spreading for a long time.

In the early days, the Gangja Suhyo Bridge was installed by on-site casting method. However, since the casting method requires transporting necessary materials to the site, it involves not only the process of installing or disassembling the formwork, but also the curing time of the concrete. There is a problem that the construction cost is relatively increased.

In order to solve the above-mentioned problem, recently, a precasting machine which is preliminarily manufactured in a factory has been widely used. As a representative example, a prefabricated reinforced concrete reinforced concrete reinforced concrete pipe (1) as disclosed in Korean Utility Model No. 195531 (published on September 1, 2000) has been disclosed. As shown in FIG. 1, the opener according to the prior art has a watertight upper watertight shape, a socket-shaped coupling part 10 at one end and a widened insertion part 20 at the other side, And the packing material 12 is injected while the coupling part and the insertion part are connected to each other in a row. As a result, precast casting water is spreading at a rapid rate because of low construction cost and quick construction.

However, there is a considerable amount of leakage from the pre-casting openings on the connection between the openings, and there is no preparation against expansion of the openings due to the temperature difference, resulting in serious leakage and damage.

Accordingly, an expansion joint device has been developed and used in order to block the leakage occurring on the connection part to the open water pipe. Fig. 2 is a diagram showing the installation state of the expansion joint device as a conventional art.
