Description

Technical Field

[0001] The patent of this invention relates to the technical field of roadbed construction, specifically, to a semi-fill and semi-excavation roadbed in mountainous areas constructed by pouring fluidized solidified soil. Background Art

[0002] In mountainous road construction, half-fill and half-excavation roadbed is a common construction method. The core method is to form an excavation area by excavating the upper part of the slope, and to form a fill area by excavating the lower part of the slope. The excavated soil is then backfilled and rolled into the fill area in layers to form a fill soil layer, and finally a flat roadbed is formed.

[0003] In order to ensure that the fill soil layer does not slide down the slope, zigzag steps are generally arranged on the fill area first, and then the fill soil layer is backfilled to form an interface layer between the fill soil layer and the steps.

[0004] In the actual construction of half-fill and half-cut roadbed, despite the adoption of zigzag steps and layered rolling and other measures, the problem of loose interface between the fill area and the cut area is difficult to eliminate, which is also an important reason for the lack of roadbed stability;

[0005] In addition, the density and strength of the fill area are still difficult to reach the level of the original weathered soil layer, further reducing the overall stability of the roadbed.

[0037] Reference Figure 1-4 The figure shows a preferred embodiment of the present invention.

[0038] The semi-fill and semi-excavation roadbed in mountainous areas constructed by pouring fluidized solidified soil comprises a cutting area 102 and a filling area 200 formed by excavating a slope soil body 100, wherein the cutting area 102 is located at the upper part of the slope 101, and the filling area 200 is located at the lower part of the slope 101, and the bottom of the cutting area 102 forms an inner roadbed 103; a plurality of steps 201 arranged open upward are provided on the filling area 200, and the plurality of steps 201 are connected in sequence along the height direction of the filling area 200 to form a continuously arranged pouring interface;

[0039] The filling area 200 is filled with a filling soil layer, which covers a plurality of steps 201. The top of the filling soil layer forms an outer roadbed 202, and the outer roadbed 202 is flush with the inner roadbed 103 to form a roadbed. The filling soil layer is formed by pouring and solidifying fluidized solidified soil, which is formed by mixing excavated soil, a solidifying agent and water, and the solidifying agent includes slag powder, fly ash, waste gypsum, water glass, stone powder slag and furnace slag.

[0040] The slope soil body 100 contains clay minerals, and the fluidized solidified soil reacts chemically with the clay minerals to integrate the casting interface with the fill soil layer.

[0041] The semi-fill and semi-excavation roadbed in mountainous areas constructed by pouring fluidized solidified soil has the following advantages:

[0042] 1) The fluidized solidified soil is formed by mixing the excavated soil, the solidifying agent and the water, wherein the solidifying agent includes multiple components, and the multiple components in the solidifying agent react chemically with the clay minerals in the slope soil 100, so that the casting interface and the fill soil layer are tightly integrated, effectively solving the problem of loose interface between the fill area 200 and the excavation area 102, thereby enhancing the overall stability of the roadbed;

[0043] 2) Fluidized solidified soil has the characteristics of self-leveling and self-compacting, which can effectively reduce the strength difference problem caused by uneven compaction in traditional layered rolling construction, and at the same time simplify the construction process, shorten the construction period, and improve the construction efficiency;

[0044] 3) Using the soil produced by excavation as the main raw material for the filling layer reduces the transportation of external earthwork and the generation of waste soil, reduces construction costs, and realizes the recycling of resources, which has significant environmental benefits.

[0045] In this embodiment, the curing agent can also be a rock and soil curing agent; compared with the traditional reaction of cement and lime with the slope soil 100, the reaction of the rock and soil curing agent with the slope soil 100 can generate more minerals such as calcium aluminate and hydrated calcium silicate, thereby connecting and wrapping the particles of the slope soil 100, so that the slope soil 100 forms a solidified soil with a certain strength.

[0046] In this embodiment, the inner side of the excavation area 102 has an open upper inclined surface 104 , and along the height direction of the excavation area 102 , the upper inclined surface 104 is inclined away from the excavation area 102 , and the upper inclined surface 104 and the inner roadbed 103 enclose the excavation area 102 .

[0047] In this way, the transition between the excavation area 102 and the filling area 200 is more natural and stable, providing a good foundation for subsequent construction and effectively avoiding roadbed deformation or slippage caused by improper connection between the excavation area 102 and the filling area 200.

[0048] In this embodiment, along the height direction of the fill soil layer, the casting interface and the upper inclined surface 104 are arranged to be inclined in the same direction.

[0049] Through the arrangement of the same inclination, a closer bonding relationship is formed between the fill soil layer and the upper inclined surface 104 of the excavation area 102, thereby enhancing the overall stability of the roadbed.

[0050] In this embodiment, the backfill soil layer is formed by multiple layers of solidified soil layers 300 stacked in sequence, and the multiple solidified soil layers 300 are combined into one; the inner side of the solidified soil layer 300 is embedded in the step 201, and the outer side of the solidified soil layer 300 is formed with a planting platform that is open upward, and plants 302 are planted on the planting platform; along the height direction of the backfill soil layer, the planting platforms of the multiple solidified soil layers 300 form a planting area 301.

[0051] The overlapping structure of the multi-layer solidified soil layer 300 not only enhances the overall strength and stability of the fill soil layer, but also realizes the ecologicalization of the roadbed through the setting of the planting platform, which helps to improve the ecological environment around the roadbed. At the same time, the growth of the roots of the plants 302 can further strengthen the soil layer.

[0052] In this embodiment, along the height direction of the fill soil layer, the planting area 301 and the upper inclined surface 104 are arranged to be inclined in the same direction.

[0053] Through the arrangement of inclination in the same direction, a more coordinated relationship is formed between the planting area 301 and the upper inclined surface 104 of the excavation area 102, which is not only beneficial to the growth of plants 302 and the improvement of the ecological environment, but also can further enhance the overall stability of the roadbed and effectively avoid roadbed deformation or slippage caused by forces in different directions.

[0054] In this embodiment, the slope soil body 100 has an original weathered soil layer, the excavation area 102 and the filling area 200 are excavated into the original weathered soil layer, and the inner roadbed 103 and the casting interface are formed in the original weathered soil layer.

[0055] This construction method makes full use of the high shear strength and low porosity characteristics of the original weathered soil layer, and establishes the construction foundation of the excavation area 102 and the filling area 200 on a more stable stratum, so that it exhibits better stability when subjected to horizontal loads, thereby effectively improving the overall stability of the roadbed and reducing the risk of roadbed deformation or slippage caused by unstable soil layers.

[0056] In this embodiment, the outer side of the step 201 is open, the inner side of the step 201 has an outer side wall 203, the slope soil 100 has an inclined hole, the inclined hole penetrates the outer side wall 203, and an inclined tube 105 is implanted in the inclined hole; the inclined tube 105 is provided with a hollow channel 106 that penetrates, and the outer periphery of the inclined tube 105 has a plurality of peripheral through holes, and the hollow channel 106 is connected to the outside through the peripheral through holes;

[0057] The inner end of the inclined tube 105 is implanted in the slope soil 100, and the outer end of the inclined tube 105 extends into the fill soil layer and is fixedly connected to the support section 204; the fluidized solidified soil fills the hollow channel 106 and is sprayed into the slope soil 100 through multiple peripheral through holes to form a whole with the slope soil 100.

[0058] In this way, not only the bonding strength between the slope soil body 100 and the filling soil layer is enhanced, but also the overall stability of the roadbed is further improved through the combination of the inclined pipe 105 and the fluidized solidified soil.

[0059] In this embodiment, the top of the solidified soil layer 300 is sunken downward to form a planting groove 303, and the planting groove 303 is filled with planting soil, and the roots of the plants 302 are planted in the planting soil.

[0060] By setting a planting trough 303 on the top of the solidified soil layer 300 and planting plants 302, not only the ecologicalization of the roadbed is achieved, which helps to improve the ecological environment around the roadbed, but also the soil layer can be further reinforced through the growth of the roots of the plants 302, thereby enhancing the stability of the roadbed.

[0061] In this embodiment, a wire mesh tube is provided in the planting groove 303, and the wire mesh tube includes an outer ring mesh layer 304 arranged in an annular manner and an inner ring mesh layer 305 arranged in an annular manner, and an outer ring area is provided between the outer ring mesh layer 304 and the inner ring mesh layer 305, and the inner ring mesh layer 305 encloses and forms a middle area;

[0062] The bottom of the outer ring mesh layer 304 and the bottom of the inner ring mesh layer 305 are connected as a whole through an annular bottom mesh layer, and the top of the outer ring mesh layer 304 and the top of the inner ring mesh layer 305 are connected as a whole through an annular top mesh layer. The outer ring mesh layer 304 is embedded in the solidified soil layer 300 and is integrated with the solidified soil layer 300.

[0063] The planting soil fills the outer ring area and the middle area, and covers the wire mesh tube; the roots of the plant 302 are placed in the middle area, and the root system of the plant 302 extends to the outer ring area.

[0064] The structure formed by arranging the wire mesh tubes not only provides good support and protection for the growth of the plant 302, but also enhances the stability of the solidified soil layer 300 through the combination of the plant 302 roots and the wire mesh tubes, effectively avoiding the loosening or deformation of the soil layer caused by the growth of the plant 302 roots.

[0065] In this embodiment, the support section 204 is covered in the fill soil layer; the cross section of the support section 204 is square-shaped, and a plurality of support tubes 206 are arranged on the outer periphery of the support section 204. The outer periphery of the support section 204 is formed with a groove 205 that is recessed inwardly, and the inner end of the support section 204 is fixedly docked on the outer periphery of the groove 205, and the outer end of the support section 204 freely extends outward;

[0066] The support tube 206 has a tube hole 209 that penetrates inside and outside, an upper through hole 207 is provided at the upper part of the support tube 206, and the top of the tube hole 209 is connected to the outside through the upper through hole 207, and a lower through hole 208 is provided at the lower part of the support tube 206, and the bottom of the tube hole 209 is connected to the outside through the lower through hole 208; the fluidized solidified soil fills the tube hole 209 and the groove 205, and the support section 204 and multiple support tubes 206 are integrated with the solidified soil layer 300.

[0067] In this way, not only the overall strength and stability of the fill soil layer are enhanced, but also the bonding strength between the support section 204 and the solidified soil layer 300 is further improved through the filling of the fluidized solidified soil, thereby improving the overall stability of the roadbed.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
