When installing rubber waterstops, pay specific attention to the following aspects. When construction workers are tying steel bars and formwork, the buried rubber waterstop must take reliable fixing measures to avoid displacement when pouring concrete. Ensure the correct position of the waterstop in the concrete. When fixing the rubber waterstop, holes can only be made in the permitted parts of the waterstop without damaging the main body. The fixing method of the waterstop should be carried out in accordance with the construction specifications required by the design. Commonly used fixing methods include using additional steel bars to fix special clamps, fixing with lead wires and templates, etc. No matter what fixing method is used, it is necessary to ensure that the waterstop is positioned accurately, without damaging the effective part of the waterstop, and to facilitate concrete pouring. They should be connected as a whole in the factory as much as possible. If due to manufacturing process, transportation conditions, etc., it is necessary to connect on site, hot-pressed vulcanized gluing (rubber waterstop) or welding (plastic waterstop) should be used. The appearance of the joint should be smooth and smooth, and the tensile strength should not be less than Of parent material. The so-called overlapping without any treatment is absolutely not allowed. The various cross-connection points of the rubber waterstop must use accessories produced by our Chenglin Company to ensure that on-site connections are only made on straight sections during construction. Flexible material with sufficient deformation ability and good bonding properties with concrete.
During the construction process of the rubber waterstop, since there are many sharp-edged stones and sharp-edged steel bars in the concrete, when pouring and positioning the waterstop, attention should be paid to the impact of the pouring, so as to avoid the impact due to the force. Too large and punctures the rubber waterstop. If any rupture is found, it should be repaired in time. Otherwise, when the joints are deformed and subjected to water pressure, the ability of the rubber waterstop to resist external forces will be greatly reduced. When positioning the rubber waterstop, be sure to keep it flat at the interface, and do not allow the waterstop to roll or kink. If it is found to be twisted and unable to unfold, it should be adjusted in time. When casting a fixed waterstop, the waterstop should be prevented from deflecting to avoid shortening on one side and affecting the waterstop effect. When pouring concrete, it must be fully vibrated to prevent the water stop from being poorly combined with the concrete and affecting the water stop effect. The waterstop joints must be well bonded. If the construction site conditions are suitable, the hot vulcanization method can be used.
