Dam upstream piping port quick blockage device and method

Abstract

The invention discloses a dam upstream piping port quick blockage device and a method. The dam upstream piping port quick blockage device comprises a bundle-shaped variable section drying water-absorbent resin, a traction umbrella, a plastic sealing bag, a geotechnical cloth bag, a balloon and the like; the quick blockage device is firstly used for searching and detecting a piping inlet; after the traction umbrella is sucked in a piping channel, the bundle-shaped variable section drying water-absorbent resin is gradually pulled into the piping channel, and is finally clamped at the piping inlet; the plastic sealing bag and the geotechnical cloth bag are cut off; and water is led into the plastic sealing bag, so that the bundle-shaped variable section drying water-absorbent resin sucks the water for expansion to block a dam upstream piping port. The quick blockage device is simple in manufacturing, cheap in material and light and convenient for carrying, has economy and practicability, and is fast in emergency blockage speed; the water-absorbent resin can absorb the water to quickly expand and cure, so that the piping port can be quickly blocked; and the construction method is simple and convenient, needs no large equipment, and adapts to characteristics and demands of dam emergency.

Description

Technical field: [0001] The invention relates to flood control and emergency reinforcement technology for embankments, in particular to a device and a method for quickly blocking an upstream pipe outlet of an embankment. Background technique: [0002] Piping refers to the phenomenon that under the action of seepage force, the fine particles in the non-cohesive soil pass through the pores formed by the coarse particles and move or are carried out by the water flow. Piping is one of the common dangers of river levee in flood season. It is one of the key contents of flood control and emergency rescue to discover the piping phenomenon in time and block the piping outlet as soon as possible. [0003] Water-absorbing resin is a new type of polymer material, which can absorb water hundreds to thousands of times its own weight, non-toxic, harmless, and non-polluting; it has extremely strong water absorption capacity and high water retention capacity. The molecular weight polymer a...

Problems solved by technology

The patent does not disclose whether the leak-stopping bag has the function of water-proofing. If there is no water-proofing function, once the leak-stopping bag touches water, before the leak-stopping bag is sucked into the piping channel, the superabsorbent resin inside the leak-stopping bag has already absorbed water and swelled, and the volume It is difficult to be sucked into the piping channel after swelling dozens of times or even hundreds of times, and the purpose of sealing the piping outlet cannot be achieved; The convenient operation can damage the leak-stopping bag and absorb water, so that the superabsorbent resin can absorb water and expand to achieve the leak-stopping effect, which needs to be further discussed
