[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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

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

[0024] The assembled solidified earth bag roadbed can use waste soil, construction waste and even solid waste as basic materials, and is solidified by using 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 meet the soil base strength requirements and reduce the interference of the external environment on the construction, is convenient for loading and unloading and transportation, is economical and environmentally friendly, and saves construction time. Among them, the prefabricated solidified earth bag units can achieve 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 solidified earth bag units is connected vertically and horizontally by snap buckles to complete paving (such as Figure 6 (as shown), solidification can be achieved through rolling compaction and physical (chemical) reactions. During the compaction process, the mixture inside the bags is squeezed and deformed by pressure. The bags, constrained by the earthbags, adapt to the pressure by changing their cross-section. Because the bags are closely packed, their degree of flattening is limited by the surrounding earthbags, gradually compacting the mixture. Paving with processed earth products offers stable material properties, low variability, excellent waterproofing, minimal rainfall impact, and improved quality assurance.

[0025] Among them, the solidified soil bag unit can be solidified in the prefabrication site 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 site 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 earthbags is preferably a three-layer composite material. The inner lining layer is required to be thin, porous, and have an adsorption effect, and materials such as redispersible latex powder can be used. The middle layer is a waterproof layer that is impermeable and requires good barrier properties, and a plastic waterproof film can be used. The outer layer is the 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 solidified earthbags can be of various shapes, mainly strips and squares, and 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-packed solidified earth products with waterproof outer packaging can prevent water damage, making the reinforced roadbed extremely durable, waterproof, and stable, and can 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 provided 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 soil 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. The glue in the two-component slow-release adhesive strip A33 and the two-component slow-release adhesive strip B34 is squeezed out and mixed under external force to seal the air vent 32, so that the solidified soil bag unit can discharge the gas in the solidified soil bag out of the bag during the rolling process, and achieve the effect of automatic closure 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 a 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 sealed 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 discarded garbage 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 solidified earthbag road base layer 20, a leveling layer 30, a base layer 40 and a surface layer 50, wherein the assembled solidified earthbag road base layer 20 adopts the above-mentioned assembled solidified earthbag roadbed.

[0033] Among them, the soil base layer is a treated 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.

[0034] Those skilled in the art will readily envision other embodiments of the present invention after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
