Problems solved by technology
Generally, the exposed outer slope of the canal embankment is exposed to the wind and sun for a long time, and it is easy to age and lose strength, so the outer slope needs to be protected; in addition, due to the poor water retention of the soil in the semi-arid area, the water seepage is serious, so for the canal embankment Said that leakage monitoring is particularly important
Currently widely used ecological concrete slope protection requires long-distance transport of cement and aggregates, etc., which will greatly increase the cost; in addition, the traditional way of checking for leaks by people driving back and forth along the embankment is labor-intensive and time-consuming for large embankments. And produce a lot of car exhaust

Embodiment Construction
[0015] For the method of protection of canal embankment and leakage monitoring in semi-arid area, figure 1 , Including the following steps:
[0016] (1) According to the actual local conditions, take local materials, select plant seeds with shallow roots and wide leaves that are common in arid areas, and mix the plant seeds with plant planting media, nutrients, water-retaining agents and water to prepare a nutrient mortar on slopes; Taking into account the existence of the infiltration line, even if the ditch 4 of the canal embankment 3 leaks, the water will basically not penetrate to the outer slope 1. There is no need to consider the problem of monitoring leakage, so the plant species on the outer slope should not be deeply rooted according to local conditions In order to prevent the root system from destroying the slope, it also needs to have wider leaves, denser growth, which can completely cover the slope surface, play a protective role, and reduce the evaporation of water i...

The invention provides a protection and seepage monitoring method for a canal dike of a semiarid region. According to the method, local soil serves as a plant planting medium, different plants are planted on an outer side slope and ground outside the side slope, and positions where the growth vigor of the plants is luxuriant serve as seepage judgment standards. The method provided by the invention is a novel protection and seepage monitoring method based on characteristics of the soil and vegetation of the semiarid region; on the basis of uniformly spraying plant seed mixed nutritional mortar to the outer side slope and the ground outside the side slope, on one hand, the different plants are planted so as to mainly play a role in protecting the outer side slope while beautify environment; on the other hand, the ground outside the side slope is treated so as to play a role in monitoring seepage; and treatment is carried out in accordance with local conditions, raw materials are gotten from local resources, the cost is low, and the effect is good.
Description
Technical field [0001] The invention relates to a method for protection and leakage monitoring of canal embankments in semi-arid areas, belonging to the technical field of maintenance and greening of canal embankments in semi-arid areas. Background technique [0002] The semi-arid areas in my country are vast, with low annual precipitation, relatively dry climate, and poor soil water retention. Therefore, the protection of canal dikes and leakage monitoring in these areas are very important. Generally, the exposed outer slope of the canal embankment is exposed to the wind and sun for a long time, and it is easier to age and lose its strength. The outer slope needs to be protected; in addition, due to the poor water retention of soil in semi-arid areas, the water seepage is more serious. Said that leakage monitoring is particularly important. At present, the widely used ecological concrete slope protection requires long-distance transport of cement and aggregates, which will grea...
