Description

Technical Field

[0001] The utility model relates to a surface soil resource protection device, in particular to a surface soil resource protection device for reducing soil resource loss, belonging to the technical field of surface soil protection. Background Art

[0002] Topsoil refers to the soil at the top of the earth's surface. Its thickness varies depending on the soil type, and is generally about 20 to 30 centimeters thick. The topsoil layer of soil is a layer of soil with dense plant roots and rich organic matter. It is the main place for the activity of organic matter on the earth. It has a large amount of organic matter and microorganisms, as well as higher levels of nutrients required for plant growth. Studies have shown that it takes 100 to 400 years to form 1 cm thick topsoil, and an average of 200 years. In farmland, it generally takes 200 to 1,000 years to form 2.5 cm thick topsoil; in woodlands or pastures, it takes longer to form the same thickness of topsoil; the formation time of topsoil in limestone areas may exceed people's imagination. Topsoil stripping refers to the stripping of the topsoil suitable for cultivation involved in construction occupation land or open-air mining land (including temporary or permanent land), and is used for stripping, storage, transportation, tillage layer construction and testing for original or off-site land reclamation, soil improvement, land reclamation and other purposes. Topsoil stripping can effectively protect the surface mature soil resources from being lost and wasted.

[0003] Collecting and piling the topsoil in an area where construction is not underway is one of the steps in topsoil stripping. The topsoil will be backfilled and used for vegetation restoration in the disturbed area before the construction is completed, and the remaining part will be transported outside the project area for disposal or consumption. Since the piled soil is mostly loose accumulation, the slope is in a critical stable state, and the surface is exposed for a long time, it is easily disturbed by external forces and causes soil erosion. Nitrogen, phosphorus and other nutrients in the topsoil are also easily lost, resulting in changes in the physical and chemical properties of the soil. Therefore, temporary piles of soil generated during the construction of production and construction projects need to be protected from soil and water conservation in a timely manner, but at present there are generally no protective measures for temporarily piled topsoil, or it is covered with a dense mesh net.

[0004] Using a dense mesh to cover the soil can provide some protection, but the protection effect is poor and cannot form a relatively complete protection system. The dense mesh is usually fixed by many stones. After the dense mesh is covered on the soil, the stones need to be placed on the dense mesh one by one. The process of finding, transporting and placing stones is time-consuming and laborious; and the stones also have a certain weight, so the work of covering and fixing the dense mesh is cumbersome and laborious, making the workload of preventing soil erosion in temporary soil dumps large.

[0028] Example 1

[0029] like Figure 1-Figure 5 As shown: A surface soil resource protection device for reducing soil resource loss includes a protective cloth 1, a clamping tube 2 and a ground nail 3. The protective cloth 1 is respectively provided with a plurality of connecting holes on four sides. The clamping tube 2 is provided in the connecting hole. The clamping tube 2 is clamped on the connecting hole. The clamping tube 2 makes it difficult for the protective cloth 1 to be damaged at the position of the connecting hole. The clamping tube 2 can form a detachable connection between each other. The protective cloths 1 are connected to each other through the clamping tube 2, thereby extending and expanding the covering range of the protective cloth 1. In actual use, the number of protective cloths 1 is selected according to needs and assembled through the clamping tube 2. The ground nail 3 is inserted in the clamping tube 2, and the protective cloth 1 is fixed by the ground nail 3.

[0030] When the soil in the temporary soil pile is covered by the protective cloth 1, the ground nail 3 passes through the clamping tube 2 downward and is inserted into the soil, so that the protective cloth 1 is fixed. It can be understood that the clamping tube 2 can be prevented from being separated from the fixation of the ground nail 3 upward by inserting the ground nail 3 obliquely into the soil or setting a limit device at the upper end of the ground nail 3; the ground nail 3 is used in conjunction with the protective cloth 1. The ground nail 3 is light and easy to carry, so the work of inserting the ground nail 3 to fix the protective cloth 1 is labor-saving and quick, reducing the workload of preventing soil erosion of the soil pile. Moreover, the clamping tubes 2 can form a detachable connection between each other, which greatly facilitates the connection and disassembly of the protective cloth 1 between each other. The coverage of the protective device can be adjusted as needed, which is also convenient for the laying and recovery of the protective cloth 1.

[0031] Example 2

[0032] This embodiment further optimizes and refines the structure of the clamping tube 2 on the basis of the embodiment 1, specifically:

[0033] like Figure 4-5 As shown: the clamping tube 2 includes a large end 4, a clamping portion 5 and a small end 6, which are connected in sequence and formed as one piece (a metal or plastic structure is adopted, and the clamping tube 2 is pre-arranged around the protective cloth 1 when the protective cloth 1 is manufactured. The clamping tube 2 can also be: a large end 4 and a clamping portion 5, a small end 6 and a clamping portion 5, one of which is a split detachable connection structure, which is convenient for installing the clamping tube 2 in the connecting hole and for later maintenance and replacement). The large end 4, the clamping portion 5 and the small end 6 are all hollow structures and are interconnected. The small end 6 of one clamping tube 2 can be detachably connected to the large end 4 of another clamping tube 2, such as a snap-on connection, a threaded connection, etc.

[0034] Example 3

[0035] This embodiment further optimizes and refines the structure of the clamping tube 2 on the basis of the embodiment 2, specifically:

[0036] The clamping tube 2 can rotate in the connecting hole, the inner cavity of the large end 4 of the clamping tube 2 is provided with an internal thread, and the outer surface of the small end 6 of the clamping tube 2 is provided with an external thread. When two clamping tubes 2 are connected, the small end 6 of one clamping tube 2 can be threadedly connected with the large end 4 of the other clamping tube 2, the structure is simple and the connection is reliable.

[0037] Example 4

[0038] This embodiment further optimizes and refines the structure of the clamping tube 2 on the basis of the embodiment 3, specifically:

[0039] The outer diameters of the large end 4 and the small end 6 of the clamping tube 2 are both larger than the outer diameter of the clamping portion 5. An inwardly concave annular groove is formed at the clamping portion 5 for installation and clamping with the connecting hole. The clamping portion 5 of the clamping tube 2 is clamped in the connecting hole on the protective cloth 1. The large end 4 and the small end 6 of the clamping tube 2 are respectively clamped on both sides of the connecting hole on the protective cloth 1 and limit the clamping tube 2 so that it cannot be separated from the connecting hole.

[0040] Example 5

[0041] This embodiment further optimizes and refines the structure of the protective cloth 1 on the basis of the embodiment 4, specifically:

[0042] like Figure 2 As shown: the protective cloth 1 described in this embodiment, the side edges of the four sides of the protective cloth 1 are respectively provided with reinforcement layers 7, and the upper and lower sides of each side edge of the protective cloth 1 are respectively provided with reinforcement layers 7 (which can be sewn reinforcement layers 7), and the connecting holes are arranged on the reinforcement layers 7. The reinforcement layers 7 make the protective cloth 1 not easily damaged at the positions of the connecting holes.

[0043] Example 6

[0044] This embodiment is based on the embodiment 5, and further optimizes and refines the structure of the ground nail 3, specifically:

[0045] like Figure 3 As shown: the ground nail 3 includes a main nail 8 and an auxiliary nail 9, the main nail 8 is inserted into the clamping tube 2 on the protective cloth 1 at the foot of the soil pile slope, the main nail 8 is fixedly provided with an auxiliary plate 10, the auxiliary nail 9 is movably installed on the auxiliary plate 10, and the auxiliary plate 10 is also used to limit the main nail 8 with the clamping tube 2 to prevent the main nail 8 from being excessively nailed into the soil, and the main nail 8 and the auxiliary nail 9 are respectively connected to the soil structure below the protective cloth 1. The protective cloth 1 is fixed together by the main nail 8 and the auxiliary nail 9 to improve the fixing effect.

[0046] Example 7

[0047] This embodiment is based on the sixth embodiment, and further optimizes and refines the structure of the ground nail 3, specifically:

[0048] The auxiliary nails 9 are inserted into the auxiliary plate 10, that is, the auxiliary nails 9 are detachably connected to the auxiliary plate 10, and can be pulled out of the auxiliary plate 10 or selectively installed on the auxiliary plate 10. If the protection device involves two or more protective cloths 1 for assembly and use, the auxiliary nails 9 are inserted into the clamping tubes 2 connected between the protective cloths 1, so that the connection between the two protective cloths 1 is connected to the soil below, thereby enhancing the anti-intrusion performance (wind and rain resistance, etc.) of the entire protection device.

[0049] It can be understood that when the protective device of the present application is arranged on a temporary pile of topsoil, the protective cloth 1 at the foot of the slope of the soil pile is fixed by a combination of main nails 8 and auxiliary nails 9, and the protective cloth 1 at other positions except the foot of the slope, such as the connection between two pieces of protective cloth 1, can be fixed by inserting auxiliary nails 9.

[0050] Example 8

[0051] This embodiment is based on the embodiment 7, and further optimizes and refines the structure of the ground nail 3, specifically:

[0052] The auxiliary plate 10 is provided with a sleeve 11 , and the auxiliary nail 9 is passed through the sleeve 11 , so that the auxiliary nail 9 can be detachably connected.

[0053] In this embodiment, the sleeve 11 is arranged obliquely relative to the main nail 8, and the sleeve 11 is arranged obliquely 10-35 degrees relative to the main nail 8. When in use, the main nail 8 is usually arranged on the protective cloth 1 at the foot of the soil pile slope, and vertically inserted into the soil below the protective cloth 1, and the auxiliary nail 9 is inserted obliquely toward the soil pile direction to improve the tightening effect of the entire ground nail 3.

[0054] Example 9

[0055] This embodiment further optimizes and refines the structure of the protective cloth 1 on the basis of the embodiment 8, specifically:

[0056] The protective cloth 1 includes an anti-oxidation waterproof layer and an anti-tension layer. The anti-oxidation waterproof layer is provided on the upper and lower sides of the anti-tension layer. The anti-oxidation waterproof layer is a thermoplastic polyolefin layer, i.e., a thermoplastic polyolefin (TPO) material is used. For example, polypropylene can be used as a base material, and an antioxidant and a softener are added to prepare the anti-oxidation waterproof layer. The anti-tension layer is a silicon crystal mesh layer, which has high tensile strength, no long-term creep, good thermal stability, and good physical and chemical stability.

[0057] In addition, the upper ends of the main nail 8 and the auxiliary nail 9 are both provided with end caps 12 to facilitate nail removal. A limiting ring 13 is also provided on the upper part of the auxiliary nail 9 to prevent the auxiliary nail 9 from being excessively inserted, and also to prevent the auxiliary plate 10 of the main nail 8 from detaching upward from the auxiliary nail 9.

[0058] How it works:

[0059] According to the size of the temporary pile of topsoil, the number of protective cloths 1 is selected. For example, two protective cloths 1 are selected, and then the two protective cloths 1 are covered on the pile. The two protective cloths 1 are connected by clamping tubes 2 and auxiliary nails 9 are inserted. The auxiliary nails 9 are used to strengthen the connection between the protective cloths 1 and the soil and prevent rainwater from entering the topsoil through the clamping tubes 2 connected between the protective cloths 1. The protective cloth 1 at the foot of the pile slope is connected and fixed to the soil below it by ground nails 3. When driving the ground nails 3, the main nails 8 are first driven vertically into the soil, and the auxiliary plate 10 is tilted at an angle of 45 degrees relative to the side of the protective cloth 1, and then the auxiliary nails 9 are driven along the sleeves 11 on the auxiliary plate 10.

[0060] In addition, in the description of the present utility model, unless otherwise specified, if the terms "multiple", "multiple roots", "multiple groups" are used, they mean two or more than two, and "several", "several roots", "several groups" mean one or more than one. In the description of the present utility model, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like are used to indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, it is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, if the terms "first", "second", "third" are used, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0061] The specific implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above implementation modes, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
