Embodiment 1

[0035] Take a Liansu UPVC drainage pipe with a length of 4m and Φ200mm and cut it into a length of 10cm. There are 38 pipes in total, and 18 of them are used as the outer mold of the concrete member. Pass the gravel through square hole sieves with apertures of 20mm and 25mm, and screen out gravels with a particle size of 20-25mm. Calculate the amount of gravel according to 1 / 2 of the volume of the 18 external molds, and then use the ratio of cementing material: aggregate = 1:7 (Mass ratio) Weigh ordinary 42.5 Portland cement, mix gravel and cement, add water slowly (water amount: cementing material = 0.28:1, mass ratio), stir for 5 minutes to make concrete mixture, pour the mixture into In the outer mold, vibrate and compact to 1 / 2 of the height of the outer mold to make 18 porous concrete specimens, water and cure for 7 days, and when the compressive strength of the concrete is greater than 5MPa, soak in clean water to reduce alkali , monitor the pH value in the water, change...

[0040] Take 20 Liansu UPVC drainage pipes with a height of 100mm and a diameter of 200mm, and use them as the outer mold of the concrete member. Pass the gravel through square hole sieves with apertures of 20mm and 25mm, and screen out gravels with a particle size of 20-25mm. Calculate the amount of gravel according to 1 / 2 of the volume of 20 external molds, and then use the ratio of cementing material: aggregate = 1:8 (Mass ratio) Weigh ordinary 42.5 Portland cement, mix gravel and cement, add water slowly (water amount: cement = 0.28:1, mass ratio), stir for 10 minutes to make concrete mixture, pour the mixture into In the outer mold, vibrate and compact to 1 / 2 of the height of the outer mold to make 20 porous concrete specimens, water and cure for 7 days, after the compressive strength of the concrete reaches 5MPa or more, soak in clean water to reduce alkali , monitor the pH value in the water, change the water when the pH is ≥ 10, and complete the alkali reduction after s...

Abstract

The invention belongs to the technical field of environment materials and ecological repairing, and discloses submerged type vegetation concrete and a preparing method and application thereof. The preparing method comprises the following specific steps that a cementing agent, aggregates and water are mixed and stirred, a porous concrete mixture is prepared and then arranged in an outer film, and formed porous concrete is obtained; after the obtained porous concrete is cured, alkali reduction is conducted; bottom mud is laid on the surface of the porous concrete obtained after alkali reduction,then, the mixture is arranged in a pouring device for pouring finishing, holes of the porous concrete are fully filled with the bottom mud, then, submerged plants are planted on the bottom mud, the bottom mud is supplemented to the surface of the porous concrete, and submerged type preparing concrete is obtained; and concrete components in which plants are planted are placed in a eutrophic waterbody to be cultured, and after plant roots are planted in the holes of the concrete, the submerged type vegetation concrete is obtained. The manufacturing process is simple, good nitrogen and phosphorus removal capability is achieved, and the submerged type vegetation concrete is suitable for concrete slope ecological improvement of parts below the riverway slope protection ordinary water level.

Description

technical field [0001] The invention belongs to the technical field of environmental materials and ecological restoration, and in particular relates to a submerged planting concrete and its preparation method and application. Background technique [0002] Since the birth of cement, concrete, as a building material, has been widely used in urban waterways and slope protection because of its low price, durability and convenient construction. With the passage of time, people have become increasingly aware of the many disadvantages of concrete slope protection, such as separating the water from the riverside vegetation, which not only makes the land vegetation lose the living space, but also makes the aquatic animals lose the place of survival and refuge, and makes the ecological function of the river channel worse. Degradation, the self-purification ability of the river is lost; at the same time, the exchange cycle between the water body and the soil is blocked, and the ability...
