The present invention relates to a sliding cover of a tunnel tunnel for civil engineering, such as a road, and more particularly, to a sliding cover of a tunnel tunnel for civil engineering such as a road so that the cover for the tunnel cavity is inserted into the cavity in a sliding manner.

In general, one side or both sides of the tunnel is provided with a common pit for the purpose of jointly receiving the buried goods, such as electricity or communication cables, gas pipes, water pipes and sewer pipes, and the buried material in the cavities can be checked in a certain section of the hollow ward. The cover is provided to be raised to a step formed at the top of the cavity.

In this way, the cover that is covered on the upper part of the cavity is covered to have a sealing property so that foreign matters, etc., from the outside are not prevented from being damaged or broken in the cavity, and the inspector or the like can sufficiently withstand the load even when the passenger passes. It is common for most of them to be made of concrete.

In addition, the handle is installed so that the inspector can easily open for inspection, etc. during the production of the concrete, when the handle is formed as a groove formed integrally on both sides of the cover, the top of the cavity sphere where the cover is raised Had to increase the width of the step formed in the.

This is because the cover can be sealed when covered with the upper part of the cavity.

In addition, when the handle is formed to have a sealability without forming an integral groove on both sides of the cover as described above, the cover is not only cumbersome but also has a complicated structure.

And, above all, the cover installed on the upper part of the conventional cavity is mainly made of concrete as described above, when the inspector wants to open the cover to check the buried material, etc. As a separate worker is required, a problem arises in that a large number of personnel must be mobilized.
