Neoprene rubber rod

Neoprene rods conventional water stop structure of the concrete face rockfill dam is usually adopts three water stop, namely in the surface layer seam set cover plate to protect plastic caulking compound, bailey, set in central seams in joint setting at the bottom of the copper water stop.The engineering practice shows that the middle water belt in the water type is difficult to combine with concrete in construction, and it often leaks.While under the effect of joint displacement, the juncture of water-stop strain of concentration is bigger, once damaged, will reduce the effectiveness of water stop structure, namely the water flow pattern in structure is flawed.

Given conventional water stop is very difficult to play a role of water normally, central China iwhr during the ninth put forward a new type water stop structure, the pattern will be the middle check hose to the surface, the embedded in the toe slab and the panel Angle and fixed bolt to fix water stop on the seam position, in order to adapt to the big joint displacement, the surface water stop great wavy design changes into ability;At the same time in order to ensure the water stop in the big seam open cases with high water pressure, in a setting water-stop seam below the support neoprene, neoprene rods shall ensure that in the process of check the moving of the water tay in seam, not by the joint mouth set up supporting neoprene bar, neoprene rods shall ensure that in the process of water stop move to stranded in the seam, not by the seam in order to play a supporting role.

Neoprene rods mainly on neoprene added with various kinds of synthetic rubber as the main raw material, mixed with various additives and fillers, classics plasticate, mixing, extrusion molding, high temperature vulcanization, it has the ageing resistance, oil resistance, abrasion resistance, is suitable for the concrete face rockfill dam in ideal material.
