[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 6 As shown, on one hand, the present invention provides an assembled cured earthbag roadbed 20, comprising: a plurality of cured earthbag layers stacked and arranged in sequence from bottom to top, wherein each cured earthbag layer comprises a plurality of cured earthbag units 1 arranged in sequence, the cured earthbag unit 1 comprises a cured earthbag 11 and a cured earth filling material 12 sealed and cured in the cured earthbag 11, and a connecting buckle 111 is arranged on the outside of the cured earthbag 11.

[0024] The assembled solidified earth bag roadbed, the solidified soil filling material can be made of abandoned soil, construction waste and even solid waste as basic materials, and is solidified by soil solidifying agent and lime, fly ash, cement and other materials in a certain proportion and bagged to form solidified earth bag units, which saves resources. Afterwards, the solidified earth bag units are used as road soil base treatment materials, and the roadbed can be formed by paving and rolling. It can not only meet the soil base strength requirements, but also reduce the interference of the external environment on the construction, and is convenient for loading and unloading and transportation, which is economical and environmentally friendly, and saves construction time. Among them, the prefabricated solidified earth bag units can realize efficient paving of the roadbed, and the connecting buckles can facilitate the assembly and transportation of the solidified earth bag units. Two-linked bags and multiple-linked bags can be formed by the connecting buckles. After the solidified earth bag units are transported to the site, the number of layers of the solidified earth bag units to be used is determined according to the depth of the soil base to be treated on site, and each layer of the solidified earth bag units is connected vertically and horizontally by buckles to complete paving (such as Figure 6 As shown in the figure, solidification can be achieved by rolling and physical (chemical) reaction. During the rolling process, the mixture in the bag is squeezed and deformed in all directions by pressure, and the bag is constrained by the soil bag. The bag adapts to the pressure by changing the cross section. Since the soil bags are closely arranged, the degree of flattening of the soil bags is limited by the side soil bags, and the mixture can be gradually squeezed and compacted. Paving with processed soil products has stable material properties, small variability, good waterproofness, little impact from rainfall, and improved quality assurance rate.

[0025] Among them, the solidified soil bag unit can be solidified in the prefabrication yard or at the construction site, and is applied to the following scenarios respectively: 1. The solidified soil mixture is bagged and transported to the site for rolling and solidification; 2. The solidified soil mixture is bagged and solidified in the prefabrication yard and then transported to the site for soft soil roadbed treatment, stone throwing and silt squeezing, gravel pile foundation reinforcement, etc.

[0026] As an improvement of the technical solution, the solidified earth bag 11 includes an inner lining layer, a waterproof layer and a surface layer from the inside to the outside.

[0027] The material of the solidified earthbag is preferably a three-layer composite material. The inner lining layer is required to be thin and porous with adsorption function, such as redispersible latex powder and other materials; the middle layer is a waterproof layer, which is impermeable and requires good barrier function, and a plastic waterproof film can be used; the outer layer is a surface layer, which requires a rough surface, stable chemical properties, good ductility, and strong impact resistance. Flood-resistant sandbag materials or geotextiles can be used. The shape of the solidified earthbag can be various, mainly strips, squares, etc., or the form and size can be determined according to the paving requirements of the construction site. Often, the failure of the soil foundation is caused by groundwater damage. Bag-cured earth products have waterproof outer packaging, which can avoid water damage, make the reinforced roadbed extremely durable, waterproof and stable, and extend the service life of the road.

[0028] As an improvement of the technical solution, the solidified earth bag 11 is provided with an exhaust structure for exhausting the gas in the solidified earth bag 11. After the gas is exhausted, the volume of the solidified earth bag unit is reduced, and the assembled solidified earth bag roadbed is more closely contacted. The exhaust structure can be a one-way exhaust valve arranged along the circumference of the solidified earth bag 11. The exhaust structure can also be as follows: Figure 4 , Figure 5 As shown, the exhaust structure includes a sealing strip 31, an air vent 32, a two-component slow-release adhesive strip A33 and a two-component slow-release adhesive strip B34, wherein the air vent 32 is arranged on the side of the solidified earth bag 11, the sealing strip 31 and the air vent 32 are arranged correspondingly, the two-component slow-release adhesive strip A33 is arranged at the lower part of the sealing strip 31, and the two-component slow-release adhesive strip B34 is arranged on the periphery of the air vent 32, and the adhesive in the two-component slow-release adhesive strip A33 and the two-component slow-release adhesive strip B34 can seal the air vent 32 after being squeezed out and mixed under external force, so that the solidified earth bag unit can discharge the gas in the solidified earth bag out of the bag during the rolling process, and achieve the effect of automatic closing of the air vent after compaction.

[0029] As an improvement of the technical solution, Figure 3 As shown, the solidified soil filler 12 can be solidified soil, and the solidified soil filler 12 can also be a solidified soil mixture. The solidified soil filler includes at least one of construction waste and solid waste. The solidified soil filler is solidified in the solidified soil bag 11 by mixing with soil solidifier and lime, fly ash and cement. The soil solidifier can further improve the durability, waterproofness and stability of the roadbed, and can extend the service life of the road.

[0030] Solidified soil can be made not only of natural soil but also of external abandoned soil mixed with soil solidifiers and materials such as lime, fly ash, cement, fiber, gravel, and construction waste; solid garbage packaged in sealed bags that meet environmental protection requirements can also be used for filling. Preferably, the solidified soil is a soil-based mixture mainly based on abandoned soil from road reconstruction projects, to which lime, fly ash, cement, fiber, gravel, construction waste and other materials can be added to improve the material strength, and solidified through compaction and physical (chemical) reaction. Among them, solid garbage containing organic matter (power plant fly ash, incineration garbage ash, etc.) can also be sealed and packaged in vacuum bags, and mixed with the solidified soil again and put into solidified soil bags for secondary sealing, which can not only store waste but also fill the roadbed.

[0031] As an improvement of the technical solution, the connecting buckle 111 is a nylon buckle, but is not limited to nylon buckle.

[0032] The present invention also provides an assembled road, which comprises, from bottom to top, a soil base layer 10, an assembled cured earthbag road base layer 20, a leveling layer 30, a base layer 40 and a surface layer 50, wherein the assembled cured earthbag road base layer 20 adopts the above-mentioned assembled cured earthbag roadbed.

[0033] Among them, the soil base layer is a processed soil base, the leveling layer is used to level the roadbed surface, and its structure is based on existing specifications. The base layer is preferably an assembled base layer for easy construction and assembly, and the surface layer is made of existing materials and technologies.
