Description
Technical Field
[0001] The utility model relates to the technical field of vegetative concrete, in particular to a vegetative concrete structure. Background Art
[0002] Vegetative concrete is a new type of concrete with ecological and energy-saving effects, which is creatively combined with the bearing performance of concrete and the growth characteristics of plants. It is an environment-friendly special concrete that allows plants to grow directly on it, and is also a technology that introduces plants into concrete structures. Existing vegetative concrete uses porous concrete as the skeleton, and fills a large number of interconnected pores in the porous concrete with suitable materials that can provide nutrients and moisture for plant growth, ensuring the growth of plant roots in the pores of the porous concrete.
[0003] According to statistics, the roof area of urban houses accounts for 20% - 25% of the urban area. If vegetative concrete can be deployed on the roof for greening, it can significantly increase the urban green volume and greening area, thereby improving the urban ecological environment, alleviating the "heat island effect" of the city and improving air quality, and being beneficial to rainwater management, protecting biodiversity, enhancing the comfort of the city, beautifying the urban landscape, etc., thus effectively improving the quality of the human living environment. On the other hand, roof greening can also extend the service life of building materials, reduce noise, lower building energy consumption, and reduce urban carbon emissions.
[0004] However, on the one hand, existing vegetative concrete is prone to water accumulation due to the need to store water, which will have a negative impact on the living and economic activities of residents below the roof. On the other hand, the quality of existing vegetative concrete is too large, resulting in the inability of the underlying roof slab to bear it, so it cannot be applied to the roof greening situation. At the same time, existing vegetative concrete also has problems such as unreasonable control of porosity and insufficient vegetation growth space. Therefore, there is an urgent need to propose a new type of vegetative concrete. Content of the Utility Model
[0005] The purpose of the utility model is to solve the technical problem that existing vegetative concrete is prone to water accumulation, which will have a negative impact on the living and economic activities of residents below the roof, and provide a vegetative concrete structure.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0007] A vegetative concrete structure, comprising:
[0008] A soil layer for planting vegetation;
[0009] A vegetative concrete layer located below the soil layer;
[0010] A drain pipe, one end of which is connected to the side wall of the vegetative concrete layer, is used to drain the accumulated water in the vegetative concrete layer.
[0011] In the vegetative concrete structure of this solution, a drain pipe extending downward is connected to the side wall of the vegetative concrete layer. When the water level in the vegetative concrete layer is lower than the connection between the drain pipe and the vegetative concrete layer, the accumulated water will not be drained by the drain pipe, and the vegetation can absorb water from the vegetative concrete layer; when the water level in the vegetative concrete layer is higher than the connection between the drain pipe and the vegetative concrete layer, the accumulated water will be automatically drained by the drain pipe under the action of gravity until the water level is equal to or lower than the connection between the drain pipe and the vegetative concrete layer.
[0012] As can be seen from the above, the vegetative concrete structure of this solution can not only automatically drain the excess accumulated water in the vegetative concrete layer through the drain pipe to prevent the vegetation from being drowned, but also will not drain all the water in the vegetative concrete layer, but will retain a certain water level of accumulated water in the vegetative concrete layer, thereby preventing the vegetation from lacking water; and the drain pipe of this solution can operate relying on gravity without the assistance of additional mechanical or electronic equipment, with a simple structure, reliable operation and low cost.
[0013] As a preferred solution of the present utility model, it further includes a water injection pipe, one end of which is connected to the side wall of the vegetative concrete layer, and the other end of the water injection pipe is connected to a water source.
[0014] The specific setting method of the water injection pipe includes but is not limited to: setting the water source below the vegetative concrete layer and making the water injection pipe extend downward; setting the water source above the vegetative concrete layer and making the water injection pipe extend upward.
[0015] This solution adds a water injection pipe, which can provide water for the roots of the vegetation by injecting water into the vegetative concrete layer to avoid the situation of the vegetation lacking water.
[0016] As a preferred solution of the present utility model, it further includes a water storage tank; one end of the drain pipe far from the vegetative concrete layer and one end of the water injection pipe far from the vegetative concrete layer are both communicated with the water storage tank.
[0017] This solution communicates both the drain pipe and the water injection pipe with the water storage tank, which can collect the drained water during the rainy season and reintroduce the water into the water injection pipe to replenish the vegetative concrete layer during the dry season, thereby realizing the recycling of water resources.
[0018] As a preferred solution of the present utility model, a one-way valve is provided in the drain pipe, and / or a one-way valve is provided in the water injection pipe.
[0019] When the one-way valve is set in the drain pipe, the one-way valve should be configured such that water can flow from the vegetation concrete layer into the drain pipe, but cannot flow from the drain pipe into the vegetation concrete layer; when the one-way valve is set in the water injection pipe, the one-way valve should be configured such that water can flow from the water injection pipe into the vegetation concrete layer, but cannot flow from the vegetation concrete layer into the water injection pipe;
[0020] This solution can prevent water from flowing back from the drain pipe into the vegetation concrete layer or from the vegetation concrete layer into the water injection pipe.
[0021] As a preferred solution of the present utility model, the vegetation concrete layer comprises lightweight aggregate and soil particles; the particle size of the lightweight aggregate is Dm, 25 mm ≤ Dm ≤ 35 mm, and the particle size of the soil particles is Da, 3 mm ≤ Da ≤ 5 mm.
[0022] The lightweight aggregate, referring to the definition of lightweight aggregate concrete, has an apparent density less than or equal to 1950 kg / m 3 .
[0023] This solution recommends that the vegetation concrete layer comprises lightweight aggregate and soil particles, and recommends the preferred particle sizes of the lightweight aggregate and soil particles. On the one hand, it can reduce the weight of the vegetation concrete layer, thereby reducing the load on the underlying structure, such as the roof floor slab, of this solution, preventing the collapse of the underlying structure and enabling this solution to have a wider application range; on the other hand, the recommended particle size combination of this solution is relatively coarse, which can form larger pores in the vegetation concrete layer for air, water, and vegetation roots to pass through, thereby not only providing sufficient growth space and nutrients for the growth of vegetation roots, but also being beneficial to solving the problem of water accumulation or water shortage in the vegetation concrete layer.
[0024] As a preferred solution of the present utility model, the thickness of the vegetation concrete layer is greater than or equal to 30 cm.
[0025] The thickness of the vegetation concrete layer is the dimension of the vegetation concrete layer in the height direction.
[0026] This solution recommends the preferred range of the thickness dimension of the vegetation concrete layer. This thickness exceeds the depth that the vegetation roots can reach, and can prevent the vegetation roots from penetrating the vegetation concrete layer.
[0027] As a preferred solution of the present utility model, a water pressure sensor is provided at the bottom of the vegetation concrete layer.
[0028] This solution provides a water pressure sensor in the vegetation concrete layer, which can detect the water level in the vegetation concrete layer through water pressure information, thereby providing data support for the watering work of the vegetation and the drainage work of the vegetation concrete layer.
[0029] As a preferred solution of the present utility model, it further comprises a retaining wall, and a waterproof layer is further provided below the vegetation concrete layer.
[0030] This solution can prevent the accumulated water in the vegetation concrete layer from spreading downward to structures such as the roof floor slab, thereby avoiding negative impacts on residents' lives or economic activities.
[0031] As a preferred solution of the present utility model, the waterproof layer is a component made of SBS material.
[0032] The SBS material, namely styrene-butadiene-styrene block copolymer.
[0033] This solution recommends the specific material of the waterproof layer, which can not only prevent the accumulated water from spreading downward to structures, but also inhibit the growth of vegetation roots, thereby preventing the waterproof layer from being penetrated by vegetation roots.
[0034] As a preferred solution of the present utility model, it further includes a retaining wall that surrounds the outside of the soil layer.
[0035] This solution can prevent soil erosion in the soil layer.
[0036] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:
[0037] 1. A vegetation concrete structure of the present utility model can not only automatically discharge the excess accumulated water in the vegetation concrete layer through a drain pipe to prevent the vegetation from being drowned, but also retain a certain water level of accumulated water in the vegetation concrete layer to prevent the vegetation from lacking water. Moreover, the drain pipe of this solution does not require additional mechanical or electronic equipment assistance, with a simple structure, reliable operation and low cost.
[0038] 2. A vegetation concrete structure of the present utility model further recommends the particle size value range of lightweight aggregates and soil particles in the vegetation concrete layer, which can not only provide sufficient growth space and nutrients for the growth of vegetation roots, but also reduce the weight of the vegetation concrete layer, thereby reducing the load on the underlying structure such as the roof floor slab.
