Problems solved by technology

However, in arid and semi-arid areas, water evaporates quickly, and the slight accumulated water at the foot of the slope will gradually evaporate over time. If the previous method of manual patrol to check the leakage of the embankment is adopted, it is easy to make mistakes as to whether there is leakage in the embankment. judge

Abstract

The invention discloses a composite brick for monitoring diversion canal dyke leakage. The composite brick is prepared from 7-8 parts of water, 45-55 parts of aeolian sand, 10-20 parts of polypropylene fiber, 10-20 parts of epoxy resin, 4-6 parts of a diluent and 10-20 parts of copper sulfate. And if the brick becomes blue, the blue position can be judged to encounter water and the dyke leaks. Thestrength is improved, so that even if water permeates into the brick body, the brick body cannot be dissolved and split, the structural stability can still be kept, and the slope toe is reinforced. Therefore, by using the composite brick, the leakage condition of the canal dyke can be monitored, and the effect of slope protection can be achieved. Monitoring personnel can discover dangerous situations at the first time through color contrast, and life and property are saved.

Description

technical field [0001] The invention relates to the production of a composite brick used for monitoring the seepage of diversion dikes, and belongs to the field of protection and monitoring of canal dikes in arid and semi-arid areas Background technique [0002] In the arid and semi-arid areas of our country, due to the dry climate, small annual precipitation, and serious shortage of water resources, a large number of water diversion channels have been built locally to store and transport water resources. However, the embankment has been impacted by water flow for a long time during its service, and it is prone to seepage. Once a seepage channel is formed inside the embankment, the water flows out from the outer slope of the embankment, causing the soil of the embankment to collapse and destroying the stability of the embankment. endanger the safety of dikes. Earth-rock dams are most vulnerable to the threat of seepage. In my country, more than 90% of dike failures are caus...
