Piping water and sand separation pressure filter well

Abstract

The present invention relates to the technical field of reverse filter trunks, and concretely relates to a piping water and sand separation pressure filter well. The filter well comprises a well-wallshell, a fine hole filter bag, a tip material filter bag and a water-absorbing mesh pressure bag, wherein the well-wall shell is made of LLDPE gum-rubber plastic material, the fine hole filter bag ismade of three-dimensional honeycomb biochemical cotton as the bag surface, the filter cotton is used as filler; the tip material filter bag is made of yarn mesh as the bag surface, the straw is used as filler; the water-absorbing mesh pressure bag is made of stainless steel mesh as support, and the braided bag is filled with high-molecular water-absorbing resin as weight. As a whole, that invention has the advantage of light weight, convenient handling and storage; strong adaptability to the site; quick assembly, overall cover piping, no need to add any materials to meet emergency requirements; meets the requirements of severe weather conditions, rapid emergency, high efficiency, simplicity, integrity and corrosion resistance; the material can be recycled and reused to reduce the cost of the material.

Description

technical field [0001] The invention relates to the technical field of reverse filter surrounding wells, in particular to a pipe gushing water-sand separation pressure filter well. Background technique [0002] Piping is a common danger in embankment engineering. Reverse filter well is one of the common methods of rescue for piping danger. It has been widely used in embankment rescue in the past. Flood control and rescue drills have also been carried out over the years as an important drill subject. This rescue method It can prevent seepage damage, prevent water gushing and sand, and efficiently eliminate the danger caused by piping, and has been used in flood prevention and rescue until now. [0003] The traditional construction method of anti-filter surrounding well: first clean the surrounding and surface of the piping, build the surrounding well with 10 times the diameter of the piping, build the surrounding well with soil bags, and layer sand, gravel or light material a...

AI Technical Summary

Problems solved by technology

The traditional filter enclosure is built with soil bags, which has low efficiency and high labor intensity. It is difficult to take soil in the harsh environment of wind and rain, the safety factor is small, and the rainwater erosion on the well wall is serious. A little carelessness can cause the well wall to collapse and endanger the safety of the embankment , causing more disasters
