Tunnel affected zone vegetation growth water test device

Abstract

The invention discloses a tunnel affected zone vegetation growth water test device in the technical field of water conservancy technology test, which comprises two sets of side plates, wherein the bottom ends of the two sets of side plates are rotatably connected with a bottom plate, the sides, which are away from each other, of the two sets of side plates are connected with a treatment box, two sets of mutually symmetrical lead screws are arranged in an inner cavity of the treatment box, the two sets of lead screws are slidably sleeved with lead screw sliding blocks, the lead screw sliding blocks are rotationally connected with the bottom end of the bottom plate through connecting rods, the top end of the bottom plate is provided with a simulation tunnel, inserting plate limiting pipes are evenly arranged between the two sets of side plates, an inserting plate is arranged between every two adjacent inserting plate limiting pipes in the front-back direction, a fine sand layer is arranged above the inserting plates, a stone layer is arranged above the fine sand layer, two sets of glass plates are arranged at the top ends of the side plates, fixing strips in the front-back directionare arranged at the bottom ends of the two sets of glass plates, front-back sliding grooves are formed in the fixing strips, sliding rods are arranged in the fixing strips, the sliding rods are horizontally and transversely arranged, and nozzles are evenly arranged at the bottom ends of the sliding rods. According to the device, soil can be rapidly replaced, a next set of experiments can be conveniently conducted, and preparation time is shortened.

Description

technical field [0001] The invention relates to the technical field of water conservancy technology testing, in particular to a water testing device for vegetation growth in tunnel-affected areas. Background technique [0002] As there are more and more examples of environmental damage caused by engineering construction, urban subways and high-speed rail tunnels will cause major changes in the distribution of surface water resources and affect the growth of plants. In the long run, it is not conducive to the coordinated development of the overall ecological environment; [0003] In the existing experimental devices, to simulate the impact of artificial rainfall on the distribution of surface water resources, we usually choose various plants for simulation, such as ryegrass, tall fescue, bermudagrass and other gramineous plants, as well as white clover, alfalfa, For leguminous plant grass species such as Amorpha fragrans and Magnolia multiflora, and shrub seeds such as Magnol...

Problems solved by technology

[0002] As there are more and more examples of environmental damage caused by engineering construction, urban subways and high-speed rail tunnels will cause major changes in the distribution of surface water resources and affect the growth of plants. In the long run, it is not conducive to the coordinated development of the overall ecological environment;

[0003] In the existing experimental devices, to simulate the impact of artificial rainfall on the distribution of surface water resources, we usually choose various plants for simulation, such as ryegrass, tall fescue, bermudagrass and other gramineous plants, as well as white clover, alfalfa, For leguminous plant grass species such as Amorpha fragrans and Magnolia multiflora, and shrub seeds such as Magnolia multiflora, Escutellaria multiflora, pigeonpea, pig dung bean, and black locust, usually choose one plant for comparison and observation, and the corresponding plants with good growth The distribution of surface water in the country is relatively abundant, so we can observe the water consumption for plant growth. When changing plant species, we need to turn over the soil and plant again. The existing device cannot quickly change the soil geology, which is time-consuming. Therefore, we propose a Vegetation growth water test device in the affected area of ​​the tunnel
