Description

A concrete structural unit for ecological bank revetment and its implementation method

technical field

The invention relates to concrete prefabricated components, in particular to an ecological revetment concrete structure unit and an implementation method thereof.

Background technique

With the continuous acceleration of urbanization in our country, the construction of ecological cities has been widely concerned by everyone, especially the ecological construction of water environment has become more and more important. Since the formal establishment of "near-natural river management engineering" in Germany in the 1950s, ecological revetment has been widely used as a practical technology in water environment ecological construction projects. In recent years, my country has begun to pay attention to the impact of river revetment construction on the ecological environment, and has carried out a series of theoretical research and technical exploration. In the construction of river water conservancy projects, Dong Zheren proposed the concept of "Eco-Hydraulic Engineering", that is, hydraulic engineering should be combined with ecological theory, not only to meet people's needs for water, but also to meet the needs of water ecosystems. integrity. The urban riparian zone connects the water and land ecological environment in the urban ecosystem, which not only plays an active role in urban flood control and waterlogging, soil and water conservation, but also has very important landscape and ecological value. Therefore, the implementation of ecological revetment has become an important link in the construction of urban rivers at home and abroad.

The river revetment using traditional hard and rigid materials cuts off the material and energy exchange of the water and land ecosystem, causing the entire revetment to become a closed system, destroying the diversity of animals and plants, causing the riparian zone to lose its ecological function, and affecting the flow of the river. Self-purification ability has led to the degradation of the river ecosystem. At the same time, there are many new types of ecological revetment components used in actual projects. Often these components are not considered comprehensive enough at the beginning of the design, and cannot flexibly meet the requirements of actual engineering for ecological revetment, so that the use of ecological revetment has not been implemented. To meet the previous design standards, for example, Chinese patent CN200810216256.0 discloses a concrete ecological revetment component, which is a group of concrete ecological revetment with various angles and shapes. The process needs to separate multiple parts for formwork prefabrication, which does not meet the requirements for large-scale construction of ecological revetments, and the actual operation is relatively unstable.

A through hole 2 is effectively connected, and the growth medium of aquatic animals and plants can be placed in the cavity structure, which increases the material and energy exchange between the revetment and the aquatic ecosystem. The involvement of no top cover also makes the revetment more open and can accommodate large-scale tower The growth of water and submerged plants also effectively improves the species diversity and self-purification ability of the water ecosystem.

The side of the carrying body 1 is provided with a card slot 3, the card slot 3 is an isosceles trapezoidal structure with an upper bottom of 3 cm, a lower bottom of 6 cm, and a bottom angle of 71.5°, which is convenient for quick implementation and stable structure. The center of the card slot 3 There is a second through hole 4 with a diameter of 3 cm. As shown in Figure 2, the cavity of the main body 1 is stacked upwards and laid layer by layer. In order to meet the requirements of different slope angles, the expansion can be realized by inserting the second through hole 4 on the slot 3. In addition, during construction, a conductive medium such as an optical fiber or a light source can be added to the second through hole 4 to guide light into the interior of the ecological bank revetment concrete structure to improve the use efficiency of the photocatalyst inside the bank revetment, thereby improving the water purification capacity; or the second An aeration pipeline 5 is added to the through hole 4 to increase the oxygen mass transfer rate of the deep water body, which has a good practical effect on preventing eutrophication of the water body.

The carrying body 1 is made of a concrete structure doped with photocatalytic materials and transparent to light and water.

The raw materials of the concrete structure include the following raw materials in parts by weight: 100 parts of cement, 30-40 parts of water, 50-70 parts of adhesive, 350-450 parts of cullet, 50 parts of mixed aggregate of fine sand and stones -150 parts, 15-20 parts of photocatalytic materials, wherein the mass ratio of stones and fine sand in the mixed aggregate of the fine sand and stones is 1:1.5, and the photocatalytic materials are titanium dioxide, zinc oxide, oxide tin or zirconium dioxide. The selected raw materials are all low in cost.
