Background
The buried water stop is an important waterproof material at the concrete joint in the tunnel, is arranged between the two liners of the tunnel, can deform along with the displacement of the deformation joint of the tunnel without losing the water stop function, and intercepts water outside the two liners by utilizing the characteristics of water stop and softness.
The conventional water stop has small transverse rigidity and is easy to bend. The quality of waterstop construction is also the waterproof important part of tunnel, at present waterstop when being under construction, one side of waterstop is set up, the opposite side is unsettled to it is flat with the waterstop "end" with the reinforcing bar checkpost, although guaranteed that the waterstop does not take place sagging, warp when being under construction, but increased the engineering time, delayed the construction progress, the invisible construction cost that has increased, and waterstop and reinforcing bar direct contact, this just causes the concrete hardly closely knit between waterstop and the reinforcing bar, the concrete between waterstop and the reinforcing bar also causes crackle, gas pocket etc. very easily in-process of going up, influence construction quality, increased the hidden danger of leaking. The steel bar clips are removed, so that the water stop is easy to sag and deform due to self gravity, and can deviate due to the impact, flow and vibration of concrete in the process of pouring concrete, and the anchoring end of the water stop cannot be completely anchored in the concrete, so that the water stop cannot fully exert the waterproof function of the water stop. Because there is no adhesive force between the rubber and the concrete of the water stop, the concrete at the joint becomes thinner after the water stop is deviated, which causes the phenomenon of 'falling blocks', and seriously affects the driving safety.
When the water stop is vulcanized in production, the sum of upper and lower semi-finished rubber sheets between the dies is larger than the thickness of the die cavity in order to ensure the appearance quality of the water stop and prevent the occurrence of adhesive shortage, rubber is in a fluid state when being pressurized and heated, and redundant rubber needs to flow out from the conveying end of the dies and can drive the reinforcing plates to change the original positions, so that the spacing between the reinforcing plates is overlarge and the products are disqualified.
