Description

Technical Field

[0001] The utility model relates to the technical field of mountaineering trails, in particular to an ecological mountaineering trail structure. Background Art

[0002] The existing hiking trails are usually constructed from the bottom up, mainly consisting of rammed earth, crushed stone cushion, concrete cushion, cement mortar bonding layer, and surface layer, which are composed of foundation and surface layer. The process flow is mortar paving, pavement brick paving, shaping, and grouting. In terms of material selection, hiking trails mostly choose non-slip and wear-resistant materials, such as stone slabs, wooden boards, concrete, etc. for pavement brick paving to maintain good stability. The structural approach of conventional hiking trails requires the cooperation of a variety of large-scale machinery for construction. The overall engineering volume is large and the damage to the original soil structure is large, which will cause a certain degree of damage to the ecological environment of the mountain. At the same time, after being eroded by rainwater and trampled many times, the existing steps are prone to loosening and offset, reducing the stability of trampling.

[0003] Therefore, how to provide an ecological mountaineering trail structure is a problem that those skilled in the art urgently need to solve. Utility Model Content

[0004] One purpose of the utility model is to propose an ecological mountain trail structure, which solves the problems of existing mountain trail structure construction technology, such as great ecological damage, large engineering workload, strong dependence on mechanical coordination, unstable later structure, and inflexible application to special terrain.

[0005] According to an embodiment of the utility model, an ecological mountain climbing trail structure includes precast concrete panels, which are buried in the land of the mountain. Angle steel and bolts are provided at the connection points of every four precast concrete panels. Every four precast concrete panels are fixed at the ends by the angle steel and bolts. The inner sides of every four precast concrete panels are filled with backfill soil, and green lawns are planted on the backfill soil.

[0006] Every four of the precast concrete panels form a "mouth"-shaped frame, and the filling soil is filled in the "mouth"-shaped frame formed by the precast concrete panels.

[0007] The backfill soil is original mountain soil, and 20% fine gravel natural soil is mixed into the backfill soil.

[0008] Every four prefabricated concrete panels form a climbing step frame, and the climbing step frames are sequentially connected to form a line of climbing trails laid on the mountain.

[0009] The prefabricated concrete slab is vertically inserted into the soil of the mountain.

[0010] A ditch for natural mountain flow is set on the hiking trail at the place where the direction of the hiking trail is inconsistent with the direction of the hillside. A ditch concrete slab is set at the bottom of the ditch for natural mountain flow, and a 1:2 waterproof mortar is set on the top of the ditch concrete slab for a flat surface.

[0011] The beneficial effects of the utility model are:

[0012] This structural approach provides a better way to bear force. After the settlement stabilizes, there will be no large deformation. It has higher stability than the structure of cushion layer plus surface layer and reduces the amount of engineering. At the same time, for mountains with larger slopes, this structural approach has no foundation and does not need to rely on large machinery for construction. It has higher flexibility and can cope with more complex terrain, reducing construction difficulty and engineering workload. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0021] refer to Figure 1 , Figure 2 and Figure 3, including a precast concrete slab 1, the precast concrete slab 1 is a precast C25 concrete slab with high strength and hardness. The precast concrete slab 1 is buried in the land of the mountain. The precast concrete slab 1 is vertically inserted into the land of the mountain. Generally, the foundation burial depth of the precast concrete slab 1 is set to 50 cm, which provides a more stable force-bearing method. The structure is not easy to deform. The precast concrete slabs 1 bite each other. After the later settlement, the precast concrete slabs 1 interact with the soil of the site, which is more stable and reduces the later maintenance cost. Further, according to the soil survey conditions, the area with poor soil conditions can appropriately increase the burial depth of the precast concrete slab 1 to reserve the settlement space of the precast concrete slab 1 in the later stage. In areas with better soil conditions, the burial depth can be appropriately shallowed. Every four precast concrete panels 1 form a "mouth"-shaped frame. The four precast concrete panels 1 enclose a step force frame. The length of one side of the precast concrete panel 1 can be determined according to the step width, and the filling soil is filled in the "mouth"-shaped frame formed by the precast concrete panels 1. Angle steel and bolts 2 are provided at the connection of every four precast concrete panels 1. The angle steel is 40x4 angle steel, and the bolt 2 is M8 galvanized bolt 2. Every four precast concrete panels 1 are fixed head and tail by the angle steel and bolt 2. The angle steel is fitted on the inner side of the adjacent precast concrete panel 1, and then the angle steel is fixed to the adjacent precast concrete panel 1 with bolts 2.

[0022] refer to Figure 3 and Figure 4 The inner side of every four prefabricated concrete panels 1 is filled with backfill soil 5, which is the original mountain soil. The soil compactness and permeability do not destroy the soil gas exchange. 20% fine gravel natural soil is mixed into the backfill soil 5, and the structural method has higher stability. Gravel, dead branches and leaves, and grass seeds can be spread on the top of the soil to increase the compactness of the top and avoid heavy rain from washing away the mud on the top. Green lawns 6 are planted on the backfill soil 5.

[0023] refer to Figure 1 and Figure 5 Every four of the prefabricated concrete slabs 1 form a climbing step frame, and the climbing step frames are connected in sequence to form a line. The climbing trail is laid on the climbing mountain. A natural overflow ditch 3 is set on the climbing trail where the direction of the climbing trail is inconsistent with the direction of the hillside. A ditch concrete slab 4 is set at the bottom of the natural overflow ditch 3. The top of the ditch concrete slab 4 is flatly provided with a 1:2 waterproof mortar on the surface to prevent rainwater from seeping in.

[0024] The working principle of this technical solution is: design the plan layout of the hiking trail through on-site survey, determine the required number and size of precast concrete slabs 1 according to the design plan; have the precast factory process the concrete slabs; clear the site, reserve space for the installation of the concrete slabs, vertically place the precast concrete slabs 1 in the site, use 40x4 angle steel and M8 galvanized bolts 2 to interlock and fix two adjacent precast concrete slabs 1, determine the basic framework of the standard steps of the hiking trail, and the height difference between the two sets of climbing step frames can refer to the standard design practice of the steps, retaining a height difference of 15 cm.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
