Description

Technical Field

[0001] The utility model relates to the technical field of footpath engineering, in particular to a footpath structure using a rail pile foundation. Background Art

[0002] In recent years, with the rapid development of my country's economy and society, outdoor sports have flourished. In order to meet the citizens' fitness and travel needs and advocate green and low-carbon travel, the construction of trails in various places has emerged. Trails are often built in the mountains and forests, connecting the main mountains in the city. Today, with the increasing requirements for environmental protection, how to minimize the impact of trail construction on the mountain environment is a key issue that we need to solve urgently.

[0003] At present, for low-filled sections, mountain forest trails mainly use two methods to deal with them: roadbed slope and shoulder retaining wall. Roadbed slope refers to setting a certain slope on one or both sides of the road during road construction so that rainwater can be discharged smoothly to avoid damage to the road and the surrounding environment. This approach is not only conducive to the long-term maintenance of the road, but also protects the surrounding ecological environment and achieves sustainable development. The shoulder retaining wall is often used to support the road filling materials, prevent soil erosion on both sides of the road, and protect the stability and safety of the road. The retaining wall can support the steep slope embankment to prevent sliding, shrink the slope foot to reduce land occupation and reduce the amount of fill.

[0004] For mountain trails, since the mountain slopes are often steep, the following problems exist during roadbed construction: it is difficult to reduce the slope and the slope stability is poor; the slope is far away, which will destroy the existing slope plants on a large scale and have a great impact on the existing environment; it is difficult for large-scale compaction machinery to enter the site and the compaction degree cannot be guaranteed; it is easy to be eroded by water, causing the stability and strength of the roadbed to continue to decline; the workload of slope protection and maintenance is large; the construction of the retaining wall foundation will cause the excavation of the mountain in sections, which has a great impact on the mountain environment; the landscape effect of the retaining wall facade is poor, affecting the appearance; when the mountain geological conditions are poor, the retaining wall has poor stability; the retaining wall masonry consumption is large; it is difficult for large-scale compaction machinery to enter the site, and the compaction degree of the fill in the retaining wall cannot be guaranteed; the existing mountain roads are narrow, and the transportation of masonry materials is difficult. Utility Model Content

[0005] The utility model provides a walkway structure adopting a rail pile foundation, without slope and excavation, thus minimizing the impact on the existing environment.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] A walkway structure using a rail pile foundation includes at least two support piles and a platform portion, wherein the two support piles are connected via the platform portion; the support piles include rail piles, wherein the rail piles include rails and a concrete layer, wherein the outer side of the rail piles is surrounded and covered with a first reinforcement layer, wherein a column is provided on the top of the rail pile, and the top of the rail pile is located inside the column, and the bottom of the rail pile is located inside the soil, and the platform portion is provided on the top of the column.

[0008] The preferred technical solution of the utility model is that the first reinforcement layer is configured by pouring concrete on the outer side of the rail pile.

[0009] An optimal technical solution of the utility model is that the columns are configured as concrete or steel structures.

[0010] An optimal technical solution of the utility model is that a second reinforcement layer is provided between the platform portion and the columns, and the second reinforcement layer includes a square steel structure formed by a plurality of transverse and longitudinal beams.

[0011] An optimal technical solution of the utility model is that the cross section of the rail pile is arranged as an "I"-shaped structure, and the length of one side of the cross section of the rail pile is shorter than the other side.

[0012] An optimal technical solution of the utility model is that the connection of the middle vertical part on the inner side of the I-shaped structure is set as a curved surface.

[0013] An optimal technical solution of the utility model is that at least 50 cm of the rail pile is located inside the column.

[0014] The preferred technical solution of the utility model is that the platform part includes a base and a railing. The base is paved above the second reinforcement layer, and the railing is located outside the base; a steel grid is paved on the base.

[0015] An optimal technical solution of the utility model is that the width of the rail pile and the first reinforcement layer is greater than the width of the column.

[0016] The beneficial effects of the utility model are:

[0017] (1) A trail structure with rail pile foundation. For low-lying fill sections, a light frame structure with micro rail pile foundation is designed. The rail pile foundation is formed by placing old rails in a drilled hole, and then pouring concrete or cement mortar to fill the space between the rails and the hole wall, so that the rails and concrete or mortar are integrated to form a micro pile.

[0018] (2) The drilling rig for rail pile foundation is small in size, light in weight, and highly maneuverable. It has relatively small requirements for the construction site and working surface, has a fast construction speed, and causes little disturbance to the in-situ soil.

[0019] (3) The columns are made of reinforced concrete structure, and the longitudinal beams and cross beams on the top of the columns are made of steel structure. The structure is light in weight, safe and reliable, convenient and flexible in construction, and does not require the erection of scaffolding. The structure is low-carbon and environmentally friendly. The damage to the mountain environment is reduced during construction. No slope or excavation is required to minimize the impact on the existing environment. The pouring of concrete on site should be minimized to reduce pollution to the environment. Stability and safety can be ensured even when the geological conditions of the mountain are poor. Light materials should be used to reduce transportation weight and solve the problem of difficulty in transportation. The form should be light and beautiful, and can be coordinated with the environment.

[0020] (4) The base is paved with steel grids, which is conducive to road drainage, sunlight exposure and the growth of ground plants. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0029] like Figure 1-5As shown, the utility model provides a walkway structure using a rail pile foundation, including at least two support piles 1, a platform portion 2 is arranged between the support piles 1, and the platform portion 2 is installed on the support piles 1 to form a walkway for people to walk. When the support piles 1 are set on a mountain slope, the platform portion 2 is installed obliquely on the support piles 1; when the support piles 1 are set on a plane, the platform portion 2 is horizontally connected to the support piles 1.

[0030] The support pile 1 includes a rail pile 101, which is a micro rail pile. The rail pile has a simple construction process and has little impact on the environment. The rail pile 101 is located in the soil, and a portion of the top of the rail pile 101 protrudes from the soil and is located in the column 103. A first reinforcement layer 102 is arranged around the outer side of the rail pile 101, that is, it is poured on the outer side of the rail pile 101 by concrete.

[0031] The column 103 is set as a steel structure or can be cast in concrete, and the width of the column is smaller than the width of the first reinforcement layer 102 and the rail pile 101, so that the support column 1 is wider at the bottom and narrower at the top, which is more stable.

[0032] A second reinforcement layer 3 is also provided between the column 101 and the platform part 2. The second reinforcement layer 3 is provided with the column 103 as a support. The second reinforcement layer 3 is provided as a steel structure longitudinal and transverse beam, and the platform part 2 is provided on the longitudinal and transverse beams.

[0033] The platform part 2 includes a base and a railing, and a steel grid 201 is laid on the base, which is beneficial to road drainage, sunlight exposure and the growth of ground plants.

[0034] The cross section of the rail pile 101 is an I-shape, one side of the I-shape is shorter than the other side, and the inner side of the connection of the I-shape is configured as an arc, so that the strength of the rail pile 101 is higher.

[0035] In order to ensure a tighter fit between the rail pile 101 and the column 103 , at least 50 cm of the rail pile 101 is located inside the column 103 .

[0036] The width of the rail pile 101 and the first reinforcement layer 102 is between 20 and 40 meters, the width of the column is between 20 and 30 meters, and the distance between the two supporting piles 1 is between 150 and 170 meters.

[0037] When a new road is built on the slope of a mountain, the small-diameter micro-rail pile foundation provided by the utility model is combined with a frame structure and paving to form a road. The rail piles greatly increase the bearing capacity and stability of the foundation, avoiding the disturbance and damage to the mountain caused by excavation. At the same time, it avoids the huge amount of excavation and filling caused by high filling and deep excavation on the slope, as well as the slope or embankment support and protection projects, which has obvious economic benefits. It reduces the safety hazards of using deep slope cutting or high filling in the layer direction, which seriously affects the stability of the slope. The upper frame-type hollow steel structure is not only light and beautiful in structure, but also economical and easy to construct. There is no need to set up cast-in-place supports, which avoids a major impact on the natural ecological environment.
