Detailed Description

The invention will be further explained below with reference to specific embodiments, without limiting the invention.

As shown in fig. 1-2, the utility model provides a novel glue injection road, which comprises a foundation soil layer 1, a gravel layer 2, a bonding glue layer 3, a fine soil layer 4, a concrete layer 5 and an asphalt layer 6, wherein the foundation soil layer 1 is positioned at the bottom for bottom support, the gravel layer 2 is positioned on the upper surface of the foundation soil layer 1, the bonding glue layer 3 is completely immersed in the gravel layer 2 for enhancing the connection between the gravels, the fine soil layer 4 is laid on the upper surface of the gravel layer 2, the concrete layer 5 is positioned on the upper surface of the fine soil layer 4, the asphalt layer 6 is uniformly laid on the upper surface of the concrete layer 5, when the structure is used for laying the ground, firstly, the ground surface is paved, and a plurality of soil layers for bedding, namely the foundation soil layer 1, are laid, because the foundation soil layer 1 has a certain thickness, in order to ensure the overall stability, therefore, when a certain height is paved, an external road roller is needed to compact the foundation soil layer 1, the foundation soil layer 1 with a certain thickness is paved, the compaction needs to be carried out for a plurality of times, the specific compaction times are determined according to the thickness of the actually paved foundation soil layer 1, after the compaction, the gravel layer 2 is paved on the upper surface of the foundation soil layer 1, the bottom support is good due to the fact that the gravel has strong supporting capacity, because the gravel is used in the gravel layer 2 and can not be completely contacted, a large amount of space capable of moving properly is left between the gravel layers 2, the space can meet the requirement that after the ground is paved, the proper heat expansion and cold contraction are carried out according to the conditions of weather and use environment, the ground can be adapted, and moisture received under the ground can be condensed and then flows out in the gap of the gravel layer 2, the water is not convenient to be stored, the ground base part is kept dry, wherein the structure is used as a road surface, the firmness degree of the road surface is important for the safety of people walking above the road surface and vehicles, therefore, when a heavier machine passes through the road surface of the structure, the road surface is pressed downwards with a larger force, so that the proper telescopic deformation is generated inside the gravel layer 2, therefore, after the gravel layer 2 is paved, the bonding glue layer 3 is filled in the gap inside the gravel layer 2, when the gravel layer 2 is paved, the compaction is required for a plurality of times, so that the gap between the gravel is smaller, the support is stable, wherein the bonding glue layer 3 is used for filling the melted glue into the gravel layer 2, and as the gravel layer 2 has a certain thickness, a part of the bonding glue layer 3 is filled after each compaction, compacting, filling and compacting for multiple times, and then paving the fine soil layer 4 after the adhesive glue layer 2 is cooled in the gravel layer 2, wherein the adhesive glue layer 3 only fills up the expansion joints in the gravel layer 2, so that the gravels between every two adjacent gravels are bonded through glue, the inside of the gravel layer 2 is better fixed, and the foundation is more firm, wherein the adhesive glue layer 3 only plays a role in connection and filling, including but not limited to asphalt liquid or silicone glue, and the like, wherein the fine soil layer 4 to be laid also needs to be laid in multiple layers, compacting is carried out, so that firmness and reliability are realized, wherein the fine soil can flow into the expansion joints which are not filled up in the gravel layer 2 in the compacting process and is properly filled, and the filling amount required by filling is extremely small due to the filling of the adhesive glue layer 3 of the shell, so that the whole thickness of the fine soil layer 4 cannot be influenced, wherein because the inside granule of thin soil layer 4 is more thin, the space of granule each other is also more, consequently also be better on absorbing bottom moisture, wherein concrete layer 5 on 4 upper surface laying of compacted thin soil layer, with bottom upper end capping, be convenient for bear the asphalt layer 6 of upper surface, make asphalt layer 6 good at concrete layer 5 fixed surface, because concrete layer 5 has certain hard degree, consequently make asphalt layer 6 after laying and shaping, holistic durable degree is better, make holistic road surface structure bearing capacity better.

As can be seen from fig. 1-2 of the specification, the thickness of the gravel layer 2 is greater than that of the fine soil layer 4, and the support stability is good because the thickness of the gravel layer 2 is relatively large and the hard part is relatively thick.

As can be seen from fig. 1-2 of the specification, the thickness of the concrete layer 5 is between the thickness of the fine soil layer 4 and the thickness of the gravel layer 2, and the thickness of the concrete layer 5 is higher than that of the fine soil layer 4 due to the function of fixing the asphalt layer 6, but is lower than that of the gravel layer 2, if the thickness is too large, the ground foundation is too high, and the cost of the concrete is too high, which is not practical.

As can be seen from fig. 1-2 of the specification, a moisture-proof cloth layer 7 is provided at the center inside the foundation soil layer 1, wherein the moisture-proof cloth layer 7 is placed inside the foundation soil layer 1, and is placed in real time during each lamination, and is compacted after the placement, so that moisture inside the foundation soil layer 1 is properly isolated, and excessive moisture is prevented from going upwards to affect the stability of the pavement structure, wherein the moisture-proof cloth layer 7 is only used for performing moisture-proof operations, and includes but is not limited to a geotextile layer or a non-woven fabric layer.

As can be known from the description attached drawings 1-2, the rubble layer 2 divide into upper rubble, middle level rubble and lower floor's rubble, the upper rubble with rubble size in the lower floor's rubble is the same, and is greater than rubble size in the middle level rubble, wherein in order to make holistic structure more stable for stability between 2 rubble layers is good, when laying, chooses for use upper strata bold rubble, middle level fritter, the overlapping mode of lower floor's bold rubble is placed, middle level fritter is convenient for when carrying out the extrusion, enter into inside the bold rubble of upper strata or lower floor, make the gap fill more full, when satisfying the thickness requirement, make the fructification degree increase.

As can be seen from the attached figures 1-2 in the specification, the vertical sections of the gravel layer 2 and the foundation soil layer 1 are both trapezoidal, and due to the trapezoidal structure, the whole structure is more stable, and the supporting effect is better.

The embodiments of the present invention are written in a progressive manner, emphasizing the differences of the various embodiments, and similar parts can be referred to each other.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
