Combined piping guide filtering device

Abstract

The invention belongs to the field of flood fighting and control equipment technology and provides a combined piping guide filtering device. The combined piping guide filtering device comprises a supporting base (1), a filtering box frame (2) and a filtering plug-in (3), wherein the supporting base (1) is a cavity structure, the filtering box frame (2) is arranged on a top portion of the supporting base (1) of the cavity structure, the filtering box frame (2) is a box-type structure and has a bottom surface opening and a side surface opening, the filtering plug-in (3) is inserted into the filtering box frame (2) through the side surface opening of the filtering box frame (2), the filtering plug-in (3) is with multiple layers successively arranged from top to bottom, and arrangement of an airproof gate at the side surface opening of the filtering box frame (2) is used for sealing the filtering plug-in (3). According to the invention, the combined piping guide filtering device can be transported and combined conveniently and rapidly. The combined piping guide filtering device can be arranged immediately after a piping dangerous situation is discovered, and piping dangerous situation is eliminated by piping gushing water convergence, water penetration and sand filtration.

Description

technical field [0001] The invention belongs to the technical field of flood control and flood control equipment, and relates to a combined piping and filtering device, which is mainly used for single and medium-sized piping that occurs on the back of a dam. Background technique [0002] Piping hazards often occur in river dykes and dams in my country, especially in the middle and lower reaches of the Yangtze River during the flood season, which can easily lead to disasters such as river embankment breaches. Therefore, piping management is a difficult problem in dam safety, flood storage, and flood relief. [0003] When piping occurs, it is necessary to seize the opportunity to eliminate the danger immediately. The best time is in the early stage. If measures are not taken immediately, the danger will develop rapidly, the degree of water gushing and sand washing will intensify, damage the dam structure and cause the dam to collapse. It can be managed immediately. [0004] T...

AI Technical Summary

Problems solved by technology

[0004] There are many commonly used methods to control piping, the main mechanism is water permeation and sand filtration, so commonly used methods include reverse filtration method, surrounding well method, water permeation method, etc. However, these methods also have shortcomings in practice , such as large area, large amount of use, long preparation and construction period, etc., it is easy to delay the timing. Although a prefabricated piping control device can make up for the above shortcomings, it also has the disadvantages of excessive overall weight, frequent operations during installation, and inconvenient use. , therefore, the commonly used methods need to be improved in order to strengthen the rapid treatment of piping
