In water conservancy project construction, ecological slope protection should not be forgotten?

In the process of water conservancy construction, ecological protection is an extremely important core task, and it is also the prerequisite and foundation for specific construction work. It can be seen that it is extremely necessary to discuss the ecological technology of slope protection in water conservancy projects. And the ecological technology of slope protection of water conservancy projects should be integrated into the construction process, and the ecological technology should be continuously improved to effectively increase the vegetation coverage rate, so that it can fully play its role in maintaining water and soil, maintain ecological balance, and prevent water and soil erosion.

1 Benefits brought by the ecological slope protection of water conservancy projects

In the past ecological slope protection process of water conservancy projects, due to the relatively simple construction method and low quality of materials, the slope protection was The performance retention time is short and the effect is not ideal. This not only greatly reduces the external image of the entire project, but also fails to restore the damaged ecological balance in the areas surrounding the construction. However, with the development and progress of technology, my country's water conservancy industry has developed rapidly, and slope protection projects have also been greatly improved, developing in the direction of more diverse methods and better effects. A task that cannot be ignored in the construction of water conservancy projects is the construction of ecological protection slopes. This work mainly plays the role of vegetation in maintaining water and soil and conserving water sources, strengthens the stabilization of land and soil in the surrounding environment of construction, and maintains the ecology of the construction area. environment. In other words, the significance of the ecological slope protection project of water conservancy projects is to alleviate the impact of water conservancy project construction on the local ecological environment, alleviate the contradiction between human activities in construction and development and the ecological environment, maintain ecological balance, and seek harmony between society and nature. develop. Because the construction of water conservancy projects involves the transformation and planning of land, it will inevitably affect local vegetation and soil quality, and reduce vegetation, which can easily lead to a series of serious ecological problems such as water and soil erosion and ecological environment imbalance. However, construction combined with ecological technology can play a role in protecting vegetation, conserving water and solidifying soil. Strengthening the research on ecological technology for slope protection in water conservancy projects can also reduce the construction cost of the project to a certain extent. Specifically, strengthening the ecological construction of slope protection in water conservancy projects will increase vegetation coverage, reduce water and soil erosion, reduce the degree to which landmarks are washed away by water due to lack of vegetation and soil, and save a lot of the cost of artificial environmental management later. What is important is that ecological slope protection must follow the laws of vegetation growth so that it can better combine economic development with protection of the ecological environment.

2 Specific measures for ecological slope protection in water conservancy projects

2.1 Utilizing vegetation concrete Utilizing vegetation concrete can give full play to the advantages of vegetation concrete’s good air permeability. Compared with ordinary concrete, it can be used The heat and moisture exchange between soil and air has been greatly improved, occupying an important position in the ecological construction strategy of slope protection in water conservancy projects. The porous structure of vegetation concrete has many advantages. Under long-term sunlight, the surface temperature of the concrete will rise very high, and the topsoil can reduce the temperature of the soil surface. In this way, the water in the soil evaporates into the surface due to the action of the topsoil, supplementing the water and nutrients needed by the plants, and creating an environment suitable for the growth of the vegetation. Among the more common mixed materials, water-retaining materials composed of inorganic water-retaining agents and organic water-retaining agents, as one of them, have good water-retaining properties and provide moisture for vegetation.

2.2 Construction of soil-retaining planting base The slope protection technology of soil-retaining planting base has become a widely used soil-retaining slope protection technology due to its strong stability and good effect in preventing water and soil erosion. method. This kind of soil-fixing planting base is mainly composed of geosynthetic materials. In other words, it is the soil-fixing technology of geotechnical units and the soil-fixing technology of geonet mats. The geomesh soil-fixing technology is made up of a combination of surrounding soil and some polymer materials. Its soil-fixing principle is to gradually form soil from the mesh mat. This soil has good toughness and high strength, and then provides a good environment for vegetation growth. Good environment.

2.3 Laying the green reproductive belt The main component of the green reproductive belt is a variety of industrial fabrics, but the green reproductive belt has very high requirements for the industrial fabrics and needs to have strong adsorption capacity. Components that can become green reproductive belts include non-woven geotextiles, nylon mesh, plant fibers formed from wheat straw, and greening materials composed of seeds, fertilizers and other substances.

The green reproductive belt itself has many advantages, such as it can automatically degrade in the soil, does not need to worry about secondary pollution, maintains soil moisture, maintains soil, etc.

2.4 Unified management system In the process of ecological design of water conservancy project slope protection, we must pay attention to the unified management system, establish a complete system, implement the system into the actual construction, and do a good job in every link, Find solutions tailored to local conditions. The specific method is that the construction unit should conduct on-site inspections of the construction site, inspect 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, the survival rate of the vegetation must also be improved. Therefore, professional training must be provided to planting personnel so that they can master the correct planting methods. Standardizing construction techniques will help increase vegetation coverage. After the vegetation is planted, it must be managed later to truly achieve the role of slope protection. For example, build guardrails next to the slope protection of water conservancy projects and put up signs such as "No Trampling" to prevent passers-by from trampling on vegetation. In addition, it is not enough to only focus on ensuring the progress of construction. The construction unit also needs to ensure the quality of construction. The most direct way is to establish a supervision system for the unit, strictly supervise every link, supervise construction regularly, constantly look for existing problems, analyze the causes of problems, and plan solutions. Strengthening quality management and supervision by construction units will help improve the overall quality of construction, better protect the ecological environment around water conservancy projects, and maintain ecological balance. The construction unit strengthens the quality management of the project, which will help to better realize ecological slope protection and ultimately achieve the unity of economic and social benefits.

2.5 Increase the control of slope protection materials. The quality of materials used in ecological slope protection projects is directly related to the final ecological slope protection effect. The construction unit's supervision of materials used in ecological construction around water conservancy projects cannot start after construction, but should be strictly controlled before construction. When selecting slope protection materials, the relevant person in charge of the construction unit must strictly check, select slope protection materials that meet standards, are reasonable and have good slope protection effects, and inspect the materials. Unqualified materials must not be selected. Some units may consider the relatively expensive price and high cost of standard materials and choose products with lower prices. Such measures will have little effect on the ecological slope protection construction of water conservancy projects, and may cause serious secondary damage to the local ecological environment. Therefore, the construction unit must adopt a rigorous and serious working attitude when selecting slope protection materials and select qualified materials responsibly.

2.6 Issues that need to be paid attention to in ecological slope protection projects of water conservancy projects. First of all, in the process of ecological slope protection, attention should be paid to scientific and technological innovation and technological progress, and new scientific and technological forces need to be introduced in a timely manner. Learning from the development results of other countries will provide impetus for the reform and innovation of ecological slope protection technology in my country's water conservancy projects. Secondly, strengthening the quality of construction materials is also an important condition for ensuring the quality of water conservancy and ecological protection projects. The use of slope protection materials should be compatible with the greening of the slope, and high-quality construction materials should be used comprehensively to provide good protection for ecological slope protection building materials. The last thing to note is the conservation of design resources. Designers should use the least resources to achieve the purpose of slope greening and select more cost-effective resources for water conservancy and ecological slope protection projects.

3 Construction process of ecological slope protection for water conservancy projects

3.1 Consolidation and leveling of slopes Consolidation and leveling of slopes is the prerequisite for ecological slope protection of water conservancy projects. Whether the slope is flat or not is directly related to the overall quality of the bricklaying work during the ecological construction process. When leveling and compacting the slope, preparations must be made. The slope of the slope protection must be measured in advance, and construction must be carried out according to the design regulations for different slopes. After the slope is leveled and compacted, bricklaying work can be carried out. Find a flat point at a suitable distance, use a level and other tools to level it, then remove weeds and other foreign matter in the bricklaying area, and then carry out subsequent work according to the design specified by the corresponding slope. During the leveling process, high-power bulldozers can be used to remove difficult protrusions, and can also be used to fill potholes and land, and then perform leveling and compaction work.

3.2 Precise bricklaying In the process of designing the ecological design of slope protection for water conservancy projects, the strength of slope protection bricklaying is also a detail work that cannot be ignored.

The relevant person in charge of the construction unit needs to rigorously and accurately calculate the amount of slope protection bricks based on the principles and requirements stipulated by the relevant slope and relevant geographical environment. Moreover, ecological bricklaying requires gaps between the bricks, and ecological bricklaying requires There are also gaps between the brickwork and the left and right toe walls. The length and width of these gaps must be accurately calculated to leave appropriate dimensions. The relevant person in charge of the construction unit must strictly supervise and control every detail of the construction project and pay attention to whether the first ecological brick is in the correct position to ensure that subsequent bricklaying will not deviate. The position of the first bricklaying has a direct impact on the quality and speed of the entire bricklaying surface.
