The present invention relates to an H-beam is installed at a predetermined distance on the side of the mountain road, and the H-beam is provided with a wire mesh to prevent falling rocks and Sato flow down to the road, and more particularly, to hang on the front lower side of the H-beam It is equipped with a transplant reinforcement barrier plate, so that it is possible to easily remove only the reinforcement barrier plate if necessary, and to easily and quickly remove the falling rocks and soils accumulated on the back side of the preventive barrier and also to change the position of the reinforcement barrier plate arbitrarily. .

In general, highways, arterial roads, and general roads that pass through mountainous areas are made by cutting down mountains, so rockfalls and sato flow from the mountain slopes around the road.

In other words, when the mountain that was frozen in winter melts in spring, falling rocks and sato flows, and when it rains a lot, the falling rainwater causes the falling rocks and sato to flow on the road.

As such, if a rockfall and a sato flow down the road and block the road, the vehicle driving on the road suddenly stops suddenly, resulting in an accident such as a car and a collision following from behind, and in the process of moving the rockfall When Ina Sato flows down, the driver unconsciously changes the direction of the vehicle, causing a major accident.

Therefore, in order to prevent this, by installing a preventive measure on the mountain roadside to prevent the falling of falling rocks and sato to prevent falling rocks and sato flowing from the mountain slopes to prevent the falling of falling rocks and sato toward the road.

On the other hand, Figure 1 shows a conventional rockfall and Sato flow prevention measures, by installing the H beam (1) at a predetermined interval on the road side and the wire mesh (3) on the grid inside the H beam (1) wire (5) Even if a rockfall or a sato flows down, it is blocked while being caught by the wire mesh 3 so as not to fall on the road. However, the conventional preventive measures have the following problems.

This is because when a long time passes after installing a roadblock on the roadside, a large amount of rockfalls and satos are blocked by the roadblocks, and thus, the accumulated rockfalls or sandows should be removed at any time. Or sand should be sprayed, but there are problems such as cost or transportation, and in the case of roads in the mountainous region, Sato was mainly used because it was blocked by preventive measures.

Therefore, if you want to remove or use the falling rocks or sand blocks that are blocked by preventive measures, the bottom of the wire mesh (3) should be rolled up and fixed and then removed or used. If the above process is repeated from time to time, there is a problem that the wire mesh (3) is easily broken and costs a lot of money to maintain or repair the preventive measures.

Therefore, this problem was solved and a removable / detachable barrier plate was installed at the bottom of the H-beam. However, since it must be assembled through bolts and nuts, the construction is very cumbersome, and the barrier plate is also composed of a plate, which is very heavy. There is a very big problem that there is a risk of being damaged by an external impact.
