Description

Technical Field

[0001] The utility model relates to the technical field of ecological restoration of engineering construction, in particular to a temporary storage bed of slope surface soil suitable for engineering project construction in mountainous and hilly areas. Background Art

[0002] During the construction of large-scale production and construction projects, the amount of earthwork excavation and backfilling is very large, which will cause certain disturbances to the environment in the project area; at this time, the topsoil protection measures of the soil and water conservation plan require the topsoil to be stripped and stored in a centralized manner before construction, and then restored after the construction is completed, so as to be used for vegetation restoration and recultivation in the project area after the construction is completed, so as to avoid the loss of topsoil resources. However, for production and construction projects located in mountainous and hilly areas, it is difficult to find flat land suitable for stacking topsoil due to the large terrain fluctuations and often crossing steep slopes. At this time, if the topsoil is improperly handled, it is very easy to cause the loss of topsoil resources, which in turn makes it difficult for the soil matrix to support vegetation growth after the construction is completed, resulting in low vegetation survival rate and ecosystem degradation in the project area. Summary of the invention

[0003] The utility model aims to provide a temporary storage bed for topsoil on a slope in response to the defects of the prior art. The temporary storage bed for topsoil on a slope is particularly suitable for the construction of engineering projects in mountainous and hilly areas. It can provide fertilizer for the topsoil during the long construction period, avoid soil compaction and hardening due to excessive stacking of the topsoil, and promote ecological restoration after the completion of subsequent projects.

[0004] In order to achieve the above purpose, the utility model can adopt the following technical solutions:

[0005] The utility model discloses a temporary storage bed for topsoil on a slope, comprising an upper opening box body of a rectangular structure formed by a vertical plate and a bottom plate, and a water-blocking cover plate sealed on the opening of the upper opening box body; air holes are evenly distributed on the vertical plates, and angle steel longitudinal legs for supporting on the slope surface are arranged at the four corners of the bottom surface of the bottom plate, a spray pipe is vertically extended upward from the center of the bottom plate, the spray pipe is provided with an atomizing nozzle located in the upper opening box body, and a liquid fertilizer box and a spray pump are located below the bottom plate.

[0006] Furthermore, a partition plate is horizontally arranged in the upper open box body, and the partition plate is movably clamped in the middle of the inner cavity of the upper open box body, thereby dividing the inner cavity of the upper open box body into an upper chamber and a lower chamber, which can avoid the compaction and hardening of the topsoil caused by stacking too high; at this time, the air holes located on the upper chamber and the lower chamber gradually increase in diameter from bottom to top, and the two adjacent rows of air holes are staggered; in addition, there are two atomizing nozzles, which are respectively located near the top of the upper chamber and near the top of the lower chamber.

[0007] Furthermore, the vertical plate is a translucent PVC plate, which can allow sunlight to penetrate into the upper chamber and the lower chamber, thereby allowing the topsoil stored in the upper chamber and the lower chamber to obtain illumination; in addition, fluorescent lamps can be arranged at the center of the bottom surface of the water-blocking cover plate and the center of the bottom surface of the partition plate, so that when there are continuous cloudy days during the construction period, the topsoil stored in the upper chamber and the lower chamber can also be illuminated by the fluorescent lamps.

[0008] Furthermore, in order to facilitate the stable construction of the upper opening box on the slope, the angle steel longitudinal legs are of a thick upper and thin lower structure, and the lower ends thereof form pointed ends that can be quickly inserted into the slope soil.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0012] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0013] like Figure 1As shown, the slope surface soil temporary storage bed described in the utility model includes an upper opening box body 1, which is used to temporarily store the surface soil stripped in the construction area of ​​the engineering construction project. The upper opening box body 1 is a rectangular structure box body surrounded by four vertical plates 1.1 and a bottom plate 1.2, and the opening of the upper opening box body 1 is covered with a water-blocking cover plate 2 for blocking rainwater. The edges of the four sides of the water-blocking cover plate 2 should be slightly larger than the edges of the upper opening box body 1, so as to form a circle of water retaining edges, which can effectively prevent the surface soil temporarily stored in the upper opening box body 1 from getting wet when it rains, thereby achieving a water-proof effect.

[0014] Air holes 3 are evenly distributed on the vertical plate 1.1 to keep the topsoil temporarily stored in the upper open box 1 ventilated at all times; angle steel longitudinal legs 4 that can be supported on the slope in the construction area are arranged at the four corners of the bottom surface of the bottom plate 1.2. The angle steel longitudinal legs 4 are of a thick upper and thin lower structure, and the lower end thereof forms a pointed end that can be quickly inserted into the slope soil, so that the upper open box 1 can be quickly and stably built on the slope in mountainous or hilly areas, solving the problem of difficulty in finding suitable flat land for stacking topsoil in mountainous and hilly areas.

[0015] In addition, a spray pipe 5 is vertically extended upward from the center of the bottom plate 1.2, and the spray pipe 5 is provided with an atomizing nozzle 6 located in the upper opening box body 1, and a liquid fertilizer box 7 and a spray pump 8 located below the bottom plate 1.2. The spray pump 8 can be opened regularly to spray liquid fertilizer onto the topsoil temporarily stored in the upper opening box body 1, so as to maintain the fertility of the soil and to improve the survival rate of the vegetation planted after the topsoil is covered.

[0016] Furthermore, a partition plate 9 can be horizontally arranged in the upper opening box 1, and the partition plate 9 is movably clamped in the middle of the inner cavity of the upper opening box 1, so as to divide the inner cavity of the upper opening box 1 into an upper chamber 10 and a lower chamber 11, which can prevent the topsoil from being piled too high and causing compaction and hardening. At this time, the apertures of the air holes 3 located on the upper chamber 10 and the lower chamber 11 gradually increase from bottom to top, and the adjacent rows of air holes 3 are staggered. At the same time, since the partition plate 9 divides the inner cavity of the upper opening box 1 into an upper chamber 10 and a lower chamber 11, two atomizing nozzles 6 should be arranged on the spray pipe 5, and the two atomizing nozzles 6 should be located near the top of the upper chamber 10 and the top of the lower chamber 11, respectively.

[0017] Furthermore, in order to allow sunlight to penetrate into the upper chamber 10 and the lower chamber 11, the vertical plate 1.1 should also be made of a light grey translucent PVC plate, so as to ensure that the topsoil stored in the upper chamber 10 and the lower chamber 11 can obtain a certain amount of light. In addition, fluorescent lamps 12 can be arranged at the center of the bottom surface of the water-blocking cover plate 2 and the center of the bottom surface of the partition plate 9, so that when there are continuous cloudy days during the construction period, the topsoil stored in the upper chamber 10 and the lower chamber 11 can also be illuminated by the fluorescent lamps 12.

[0018] The topsoil stripped from the construction area of ​​the engineering construction project is temporarily stored in the upper open box 1 formed by the vertical plate 1.1 and the bottom plate 1.2, which can effectively prevent water and air from hardening and avoid the loss of topsoil resources. At the same time, liquid fertilizer can be sprayed on the topsoil temporarily stored in the upper open box 1 regularly to keep the soil fertile, so as to improve the survival rate of vegetation planted after the topsoil is recovered. In addition, the angle steel longitudinal legs 4 evenly distributed on the bottom plate 1.2 can also facilitate the construction of the upper open box 1 on the slope of mountainous or hilly areas, solving the problem of finding suitable flat land for stacking topsoil in mountainous and hilly areas.

[0019] The following is an example of a production and construction project in the northern soil and rock mountain area. The project is located in the northern soil and rock mountain area. The climate belongs to the temperate monsoon climate zone, with a mild climate and summer rainfall accounting for 70% of the annual rainfall. The terrain of the project area is mountainous and hilly, and the soil is brown soil. The construction road and the main project of this project are located on the hillside. The soil and water conservation plan requires that the topsoil of the project area be stripped and stored before construction, and then returned after the project construction is completed, and vegetation restoration or recultivation, etc. are carried out. During construction, first set up the slope surface soil temporary storage bed described in the utility model on the slope surface in the project area; then strip the surface planting soil of about 30cm in the temporary occupied area in the project area, and store it in the upper chamber 10 and the lower chamber 11. When it is cloudy for more than 2 days during the construction of the project, the fluorescent lamp 12 at the center of the bottom surface of the water-blocking cover plate 2 and the partition plate 9 can be opened to irradiate the topsoil, thereby having a favorable effect on the growth of microbial groups in the soil, which is conducive to the growth of microorganisms and helps to change the soil moisture. When the construction period of the project is long and the temporary storage time of the topsoil exceeds one growing season, the spray pump 8 can be turned on once a week to spray the liquid fertilizer stored in the liquid fertilizer box 7 onto the temporary storage of the topsoil in the upper chamber 10 and the lower chamber 11. The liquid fertilizer is mainly liquid carbon fertilizer, and the spraying time is 6 to 8 hours to keep the topsoil fertile and improve the survival rate of vegetation planted after the topsoil returns.

[0020] After the main project is constructed, multiple pits can be excavated at reasonable locations in the project area. The pit dimensions are 4m long, 2m wide, and 0.3m deep. The distance between adjacent pits is 0.5m. The excavated soil is spread around the pits with a thickness of about 0.2m. Then the topsoil temporarily stored in the upper opening box 1 is taken out and returned to the pit together with some dead leaves. The slope topsoil temporary storage bed can be reused after use. After that, plants adapted to the surrounding environment can be planted on the topsoil in the pits.
