Description

Technical Field

[0001] The utility model relates to the technical field of ecological concrete, in particular to an ecological concrete specimen convenient for plant planting. Background Technique

[0002] Ecological concrete is concrete on which plants are planted on the surface of porous concrete. It is a special functional building material with a porous structure in the shape of "rice flower candy" formed by bonding a layer of cement paste on the surface of coarse aggregates. There are a large number of continuous pores inside it and the alkalinity is moderate. The ecological concrete technology has been developed on the basis of the past requirements for the strength and durability of concrete, further combined with environmental problems, coordinated the ecological environment, reduced the environmental load, preserved and improved the environmental landscape, making the concrete an ecological material that integrates with nature and has a positive protective effect on the natural environment and ecological balance.

[0003] Before ecological concrete is put into use, in order to ensure its quality, a vegetation test is often carried out. After retrieval, the patent authorization announcement number CN 212568791 U discloses a vegetation concrete specimen device convenient for plant planting, "including a vegetation concrete specimen, an anti-corrosion wooden frame and a bottom plate; a wooden fixing handle is arranged on the outer end face of the anti-corrosion wooden frame, and a connecting hole is arranged at the bottom of the anti-corrosion wooden frame; the bottom plate includes a round hole plate and a water baffle arranged below the round hole plate. The round hole plate is evenly distributed with water permeable holes. The water baffle is composed of a square frame and evenly distributed parallel water baffle strips. A chute is respectively arranged on both sides of the lower end face of the round hole plate, and a sliding block embedded in the chute and sliding along the chute is respectively arranged on both side end faces of the water baffle; a circular slot is arranged on the side end face of the round hole plate; it also includes a connecting bolt for passing through the connecting hole and inserting into the circular slot". However, in the above device, the bottom plate and the anti-corrosion wooden frame are fixed to each other through a total of eight connecting bolts installed around. When disassembling and assembling the device, tools are needed to screw the connecting bolts into or out of the slot one by one, which still takes a lot of time, the disassembly and assembly efficiency is not high, and the use is not convenient enough.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 - 3 , in the embodiment of the present utility model, an ecological concrete specimen facilitating plant cultivation includes a bottom plate 1 and a box frame 2. The box frame 2 is arranged on the bottom plate 1. Positioning pins 4 are installed in the middle of the upper end faces on both sides of the bottom plate 1, and the positioning pins 4 are in plug-in fit with the positioning holes 5 correspondingly opened on the bottom surface of the box frame 2. An ecological concrete specimen body 17 and a planting soil layer 18 are sequentially arranged in the box frame 2 from bottom to top. Handles 16 are installed on the front and rear outer walls of the box frame 2. The arrangement of the handles 16 can improve the convenience of carrying the box frame 2. Water permeable holes 3 are evenly opened on the bottom surface of the bottom plate 1. The arrangement of the water permeable holes 3 can facilitate the downward seepage of water in the ecological concrete specimen body 17.

[0021] Please refer to Figures 1 - 2 , limiting plates 6 are installed at both the front and rear ends of the box frame 2. An inner cavity 7 is opened in the limiting plates 6. A wheel body 8 is installed in the middle of the inner cavity 7. The wheel shaft of the wheel body 8 is rotatably connected to the limiting plates 6, and one end of the wheel shaft of the wheel body 8 is fixedly connected to a knob 9 located outside the limiting plates 6. Insertion rods 12 are arranged on both sides of the wheel body 8. Baffles 13 are installed on the insertion rods 12. Springs 14 are sleeved on the insertion rods 12. Both ends of the springs 14 are in contact with the baffle 13 and the inner wall of the inner cavity 7 respectively. The insertion rods 12 are in plug-in fit with the slots 15 opened on the side walls of both sides of the bottom plate 1. Limiting openings 11 are opened on the wheel body 8. The limiting openings 11 are adapted to the limiting columns 10 installed on the inner cavity 7. The limiting openings 11 are circular arc openings.
