Slogan of concrete strength

An important work in water conservancy project construction is the construction of ecological slope protection, which mainly plays the role of soil and water conservation of vegetation, strengthens the stability of land and soil in the surrounding environment and maintains the ecological environment of the construction area. In other words, the significance of ecological slope protection project of water conservancy project lies in alleviating the influence of water conservancy project construction on local ecological environment, alleviating the contradiction between human activities and ecological environment in construction and development, maintaining ecological balance and seeking the common development of social and natural. Because the construction of water conservancy projects involves land transformation and planning, it will inevitably affect the local vegetation and soil quality, reduce vegetation, and easily lead to a series of serious ecological problems such as soil erosion and ecological environment imbalance. However, the construction combined with ecological technology can protect vegetation, contain water and consolidate soil. Strengthening the research on ecological technology of slope protection of water conservancy projects can also reduce the construction cost to some extent. Specifically, strengthening the ecological construction of slope protection of water conservancy projects will improve vegetation coverage, reduce soil erosion, reduce the degree of landmarks being washed away by water due to lack of vegetation, and save a lot of money for artificial environment control. It is important that ecological slope protection should follow the law of vegetation growth, so that economic development and ecological environment protection can be better combined.

Specific measures for ecological slope protection of water conservancy projects

1 Use vegetation concrete

The use of vegetation concrete can give full play to the advantages of good air permeability of vegetation concrete. Compared with ordinary concrete, it can greatly improve the water and heat exchange between soil and air, and it plays an important role in the ecological construction strategy of slope protection in water conservancy projects. The porous structure of vegetation concrete has many advantages. Under the long-term sunshine, the surface temperature of concrete will rise very high, and the surface soil can reduce the surface temperature of soil. In this way, due to the action of topsoil, the water in the soil evaporates to the surface, which supplements the water and nutrients needed by plants and creates an environment suitable for plant growth. Among the common mixed materials, the water-retaining material composed of inorganic water-retaining agent and organic water-retaining agent, as one of them, has good water-retaining performance and provides water for vegetation.

2. Build a solid soil planting base.

Slope protection technology has become a widely used soil reinforcement method because of its strong stability and good effect of preventing soil erosion. This kind of soil-fixing planting base is mainly composed of geosynthetics, in other words, it is the soil-fixing technology of geotechnical units and the soil-fixing technology of geotextile mats. Geonet mat is a combination of surrounding soil and some polymer materials. Its soil consolidation principle is that the soil is gradually formed by a net mat, which has good toughness and high strength, thus providing a good environment for vegetation growth.

3. Laying green belts

The main components of green belt are all kinds of fabrics, but the green belt has high requirements for fabrics and needs strong adsorption capacity. The components that can become green belts include nonwoven geotextiles, nylon nets, plant fibers formed from wheat straw and greening materials composed of seeds, fertilizers and other substances. Green belt itself has many advantages, such as automatic degradation in soil, no need to worry about secondary pollution, and maintaining soil moisture and soil conservation.

4 unified management system

In the process of ecological design of slope protection of water conservancy projects, we should pay attention to the unified management system, establish a complete system, implement the system in actual construction, conscientiously do every link and find solutions according to local conditions. Specifically, the construction unit should inspect the construction site, check the environment of the construction site, and select suitable plant species with strong adaptability for ecological construction according to different environments. Although the selected vegetation has strong adaptability, it is necessary to improve the survival rate of vegetation, so it is necessary to provide professional training for growers so that they can master the correct planting methods. Standardizing construction technology is helpful to improve vegetation coverage. After the vegetation is planted, it needs post-management to truly achieve the role of slope protection. For example, fences are added next to the slope protection of water conservancy projects, and signs such as "No Treading" are set up to prevent passers-by from trampling on vegetation. In addition, it is not enough to ensure the construction progress, and the construction unit also needs to ensure the construction quality. The most direct way is to establish the supervision system of the unit, strictly supervise every link, and regularly supervise the construction, constantly look for existing problems, analyze the causes of the problems and plan solutions. Strengthening the quality management and supervision of the construction unit will help to improve the overall quality of the project construction, better protect the ecological environment around the water conservancy project and maintain the ecological balance. Strengthening project quality management by the construction unit is helpful to better realize ecological slope protection, and finally realize the unity of economic and social benefits.

5. Strengthen the control of slope protection materials.

The quality of materials used in ecological slope protection project is directly related to the final ecological slope protection effect. The supervision of the construction unit on the materials used in the ecological construction around the water conservancy project should not begin after the project construction, but should be strictly controlled before the construction. The relevant person in charge of the construction unit must strictly control the selection of slope protection materials, select slope protection materials that meet the standards, are reasonable and standardized, and have good slope protection effect, and test the materials, and resolutely cannot choose unqualified materials. Considering the high price and cost of standard materials, some units may choose products with lower prices. Such measures will make the ecological slope protection construction of water conservancy projects have little effect, and may seriously cause secondary damage to the local ecological environment. Therefore, the construction unit must uphold a rigorous and serious working attitude when selecting slope protection materials, and select qualified materials responsibly.

6 problems that should be paid attention to in ecological slope protection project of water conservancy project

First of all, in the process of ecological slope protection, we should pay attention to scientific and technological innovation and technological progress, and need to quote new scientific and technological forces in time and learn from the development achievements of other countries to provide impetus for the reform and innovation of ecological slope protection technology of water conservancy projects in China. Secondly, strengthening the quality of building materials is also an important condition to ensure the quality of water conservancy ecological protection projects. The use of slope protection materials should be adapted to the greening of slopes, and high-quality building materials should be used comprehensively to provide good protection for ecological slope protection building materials. Finally, we should pay attention to saving design resources. Designers should use the least resources to achieve the purpose of slope greening, and choose more cost-effective resources for water conservancy ecological slope protection projects.

Ecological construction technology of slope protection in water conservancy project

1 The slope is compacted and leveled.

It is the premise of water conservancy ecological slope protection to do a good job of tamping and leveling slope surface. In the process of ecological construction, whether the slope is flat or not is directly related to the overall quality of bricklaying. In the process of leveling and tamping the slope, it is necessary to make preparations, measure the slope of the slope protection in advance, and carry out construction according to the design regulations of different slopes. After leveling and tamping the slope, bricklaying will be carried out. Find a flat point with a suitable distance, level it with a level and other tools, then remove weeds and other foreign objects in the bricklaying area, and then carry out future work according to the design specified by the corresponding slope. In the process of leveling, you can use high-power bulldozers to remove difficult protrusions, or you can use high-power bulldozers to fill pits and depressions, and then level and tamp them.

2 accurate bricklaying

In the process of designing the ecological design of slope protection of water conservancy projects, the strength of slope protection brick is also a detail work that can not be ignored. The relevant person in charge of the construction unit needs to calculate the amount of bricks used for slope protection strictly and accurately on the basis of the principle requirements stipulated by the relevant slope and geographical environment. Moreover, ecological bricklaying requires gaps between bricks, and gaps between ecological bricklaying bricks and left and right toe walls. The length and width of these gaps should be accurately calculated and appropriate dimensions should be left. The relevant person in charge of the construction unit should strictly supervise and control every detail of the construction project, and pay attention to whether the position of the first ecological brick is correct, so as to ensure that the subsequent bricks will not deviate. The position of the first bricklaying directly affects the quality and speed of the whole bricklaying surface in the future.
