Rescue pipe and emergency rescue pipe fitting for dam piping accident and use method of emergency rescue pipe fitting

Abstract

The invention relates to the technical field of dam piping emergency treatment, in particular to a rescue pipe for a dam piping accident. The rescue pipe for the dam piping accident comprises a steel pipe and further comprises a sliding ring connected to the portion, close to the bottom end, of the steel pipe in a sliding mode, and anchor thorn pressure induction type firing pin blasting packages are distributed at the upper end of the sliding ring in the circumferential direction, wherein a adhesive bag and a small expansion ball bag are tightly attached to the left side and the right side of the pressure induction type firing pin blasting bag respectively. The rescue pipe provides a new water stopping method which can be regarded as a whole in which two leaking stoppage structures acting on different positions promote each other, and after the emergency rescue pipe fitting acting on a piping opening is added into the pipe, the pipe not only plays a role in fixing the emergency rescue pipe fitting main body, most importantly, the leaking stoppage function of the pipe is combined to quickly form a leaking stoppage layer at three layers of filter screens, so that efficiency is greatly improved, water can be quickly stopped, and repair time is shortened; the rescue pipe not only acts on a common river levee, but also can be used for a river levee dam with water on the two sides, and blocking of a low-water-level dam is rapid and effective.

Description

technical field [0001] The invention relates to the technical field of embankment piping emergency treatment, in particular to a rescue pipe for embankment piping accidents, an emergency rescue pipe fitting and a use method thereof. Background technique [0002] Under the action of seepage, the fine particles of the soil form pores along the skeleton particles, and the increase of the flow rate of water in the pores of the soil causes the fine particles of the soil to be washed away, which is called piping. When piping occurs, the water surface will be turned upside down. As the upstream water level rises, the duration will prolong, and the danger will continue to worsen. A large amount of water gushes up and overturns the sand, which destroys the foundation soil skeleton of embankments and sluices, expands the channels, and empties the foundation soil, causing buildings Collapse, causing accidents such as embankment bursting, dam collapse, gate switching, etc., so there is ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide emergency rescue pipe fittings for embankment piping, to solve the emergency rescue mode of general piping at present, the reverse filter surrounding well and the form of raising water basin are used more, but the materials used for the current reverse filter surrounding well are Soil bags, sand pads or firewood filter materials, this method does not have professional processing equipment, the work efficiency is low and a lot of manpower and material resources are wasted, and it may not be able to produce a good water-stop effect; secondly, the water basin method can only be used upstream and downstream In areas where the water level difference is not large, the limitations are obvious, and the effect equipment is relatively simple and cannot be used universally. In addition, the traditional method of dams with water on both sides cannot be targeted in real time, and the low water level dams are relatively slow to block.
