Problems solved by technology

[0004] The invention provides a lateral permeable road and its construction method that can solve the problem of road water passing, that is, by embedding a certain amount of treated permeable material under the roadbed foundation, and using the material's permeable properties, when water needs to flow from one side of the road to the other When one side flows, it can flow directly to the other side through the permeable layer instead of the road surface, which can not only make the water drain quickly, but also reduce the impact of accumulated water on the road surface

Embodiment 1

[0021] A lateral permeable road, comprising: laying treatment soil layers 2 from bottom to top; laying clay compaction layer 3 on treatment soil layer 2; laying permeable layer 4 on clay compaction layer 3, said permeable layer consisting of Composed of gravel bags 1, the permeable gravel bags 1 are staggered and closely arranged; a leveling layer 5 is laid on the permeable layer 4; a pavement surface layer 6 is laid on the leveling layer 5, and the permeable gravel bags 1 include a permeable woven bag 12. The permeable woven bag 12 is filled with crushed stones 11 with a particle size of 15-25 mm, and the filling amount of the crushed stones is one-third to two-thirds of the capacity of the permeable woven bag 12 .

Embodiment 2

[0023] A construction method for a lateral permeable road, comprising the following steps:

[0024] Step 1 Carry out filling earthwork construction for the lower part of the soil foundation, and the filling soil is required to be 6% lime treatment soil. After the excavated road embedding is completed, the lime treatment soil is turned and compacted to form a 600mm thick treatment soil layer 2 ,

[0025] Step 2 After laying a geomembrane above the treatment soil layer 2, fill a 100mm thick clay layer above it and compact it to form an impermeable clay compaction layer 3,

[0026] Step 3 Put gravel 11 with a particle size of 15-25 mm into a permeable woven bag 12, and seal it to make a permeable gravel bag 1. The filling amount of gravel is one third to three times the capacity of the permeable woven bag. two-thirds,

[0027] Step 4: Pave the permeable woven bags 1 layer by layer and arrange them tightly on the top of the clay compaction layer 3. The number of laying layers is...

Abstract

The invention provides a lateral permeable road and a construction method thereof. A subgrade is formed by paving a treated soil layer, a clay compacted layer and a permeable layer from bottom to top respectively, wherein the permeable layer is composed of permeable broken stone bags which are closely arranged in a staggered manner; a leveling layer and a pavement surface are paved on the permeable layer. The construction method comprises the following steps: performing filling earthwork construction on the bottom part of the subgrade, mixing lime treated soil in the excavated road cutting and then compacting to form the treated soil layer; paving a geomembrane, putting a clay layer on the geomembrane and compacting to form the clay compacted layer; putting broken stones in permeable woven bags and sealing to form the permeable broken stone bags; flatly laying the permeable woven bags in a layered manner and closely arranging the permeable woven bags above the clay compacted layer, closely arranging the permeable broken stone bags of every two adjacent broken stone permeable layers in a staggered way and filling the gap between the adjacent broken stone permeable layers with the broken stones, thereby forming the permeable layer; putting soil on the permeable layer and compacting to form the leveling layer; performing pavement construction on the leveling course.

Description

technical field [0001] The invention relates to a lateral permeable road and a construction method thereof, in particular to a roadbed construction technology which enables the roadbed to pass through water quickly by improving the roadbed material. Background technique [0002] In many cases, the subgrade needs to pass water. In some special cases, such as floods, how to quickly and safely pass the water through the road is also an urgent problem to be solved. Time soaking is likely to cause damage. Especially in mountainous areas, the grade of roads is low, and due to the constraints of terrain, geology and insufficient investment, it is very difficult to build bridges and culverts. The embankment may be hollowed out causing the road to collapse. [0003] At present, two methods are mainly used to solve the road water passing technology: one is to bury culverts in the roadbed or directly erect bridges, and the water directly passes under the road; the other is to...
