ARC-SHAPED DIVIDED SEGMENTS FOR NON-EXCAVATION TYPE CONSTRUCTED TUNNELS AND CONSTRUCCTING CONDUITS

摘要

The present invention relates to arc-shaped segmentation segments for construction of non-adhesive temporary tunnels and pipelines, and in particular, bent using corrugated or uneven plates, and four or more coupling plates are installed to be coupled to each other through several coupling means to form a circular or arcuate shape. Alternatively, in the arc-shaped splitting segment for non-attached temporary tunnel and pipeline construction, which are assembled and installed in other polygonal shapes, a liquid rubber coating layer is applied to the inner and outer surfaces of the arc-split segment with a predetermined thickness, and the four sides of the arc-split segment. It characterized in that the water-resistant rubber molded water-resistant material is attached to the outer side of the two bonding plates adjacent to each other fixedly installed in the bonding plate. In this way, a liquid rubber coating layer is applied to the inner and outer surfaces and side bonding plates of the arc-shaped segmentation segment used to construct the non-adhesive tunnel and the pipe for the temporary construction, and if necessary, a transparent hardner coating layer is selected on the outer surface of the liquid rubber coating layer. Corrosion resistance, abrasion resistance and corrosion resistance of the arc segmented segment itself can be greatly improved, and liquid rubber coated on the outside of the joining piece when constructing non-adhesive temporary tunnels and pipelines by combining several arc segmented segments. The coating layer greatly improves the watertightness to the joints, and if necessary, the watertight rubber-formed index material is additionally attached to some side joining plates to completely prevent leakage of the indexes through the joints of the arc segment segments. It can be prevented.
