Rubber waterstop for construction joints
one The rubber waterstop used for construction joints shall not be exposed to the sun for a long time in the open air to avoid rain, and shall not be touched by highly polluting chemicals.
two During transportation and construction, machinery and reinforcement shall not damage the waterstop.
three During construction, the waterstop must be firmly fixed to avoid shifting during concrete pouring and ensure the correct orientation of the waterstop in the concrete.
four . The methods for fixing the waterstop are: use additional steel discs for fixing; Fixture fixation; For lead ratio and formwork fixation, if perforation is required, it can only be carried out in the marginal installation area of the waterstop first, and other parts shall not be damaged.
During the installation of rubber waterstop for construction joints, it is required that the interface connection is simple, safe and reliable. The hot welding method or hot vulcanization method can be used for butt joint on the site to ensure the quality of the lap joint of the waterstop is safe and reliable, so that the construction joint expansion joint The waterproof quality provides a more complete, safe and reliable guarantee.
The rubber waterstop used for construction joints can be inspected and repaired daily. The pre set grouting conduit can be used for water leakage detection. If the construction joint leaks due to the quality of the waterstop or construction quality and other reasons, a second waterproof and ground defense should be set up. The grouting pipe can be used for effective, economical and rapid grouting repair, so that the waterproof quality of the construction joint and deformation joint becomes more safe, reliable and durable.
