Description

Technical Field

[0001] The utility model relates to the technical field of waterstop belts, in particular to a temporary fixing device for connecting waterstop belts. Background Art

[0002] Due to the increase in heavy rain in recent years, the original rainwater culverts in municipal projects can no longer meet the drainage requirements of heavy rain. The newly built drainage system now uses rainwater box culverts instead of rainwater culverts. A settlement joint is set every 20 meters or so for the rainwater box culvert, and the settlement joint adopts dual waterproof measures of embedded waterstop and external waterstop. The waterstop joint can be connected by hot melt connection and cold connection (bonding). When hot melt connection, you only need to fix the waterstop in the hot melt welding machine to complete the connection. However, when cold connection, after the joint is fully coated with glue, it needs to be fixed manually by hand. After the glue is strong, it can be released from the hands. This process requires a long time of labor and requires high hand-holding stability.
