Closely knit；
S4, making blotter, point two-layer making, every layer thickness is 90-100mm, and the rubble of lower level floor embeds element soil
In；
S5, making geogrids layer: point two-layer making, first making steel plastic geogrid, repave stone powder levelling；
S6, making reinforced concrete floor: in described geogrids layer, in pile for prestressed pipe assembling reinforcement weld around shape
Becoming tiling grid shape bar-mat reinforcement, casting concrete on described bar-mat reinforcement and described pile for prestressed pipe, described concrete is by weight
Mark is poured formed in stone 10%-15%, cement 22%-35%, sand 30%-40%, the ratio of water 20%-30%；
S7, making anti-filter geotechnique's layer of cloth；Described anti-filter geotechnique's layer of cloth includes anti-filter geotextiles and covers anti-filter geotechnique
The geomembrane on cloth surface；
S8, pours bitumen layer；Divide three layers to pour, every layer of 5cm.
Preferably, described rhone is less than original place roadbed 1.6m；Described excavation target depth is 50mm.
Preferably, the weight fraction ratio of described Calx and described element soil is 0.18:1, and the compactness of described basic unit is
90%.
Preferably, described blotter by cobble or particle size range 30～40mm crushed stone roll laying and form.
Preferably, in described stone powder, stone, stone powder, white lime granule, the weight fraction ratio of miscellaneous soil are 42:37:
11:10。
The present invention at least includes following beneficial effect:
Roadbed construction method of the present invention, after excavating rhone outside roadbed, placing pile for prestressed pipe, opens
After digging basic unit, making blotter, geogrids layer, reinforced concrete floor, anti-filter geotechnique's layer of cloth and bitumen layer successively, effectively
Consolidate basic unit, improve antiseepage, thus reduce settling amount.
Part is embodied by the further advantage of the present invention, target and feature by description below, and part also will be by this
Invention research and practice and be understood by the person skilled in the art.
Accompanying drawing explanation
Fig. 1 is the flow chart of roadbed construction method of the present invention.
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to description literary composition
Word can be implemented according to this.
Should be appreciated that used herein such as " have ", " comprising " and " including " term do not allot one or many
Other element individual or the existence of a combination thereof or interpolation.
As it is shown in figure 1, the present invention provides a kind of roadbed construction method, comprise the following steps:
S1, removes original place surface irregularities, excavates rhone outside the roadbed of original place,
S2, the unwrapping wire of pile for prestressed pipe positions, press-fits, determines stake；
S3, original place road excavation forms basic unit to target depth, rolls levelling with the element soil doping of described basic unit for Calx
Closely knit；
S4, making blotter, point two-layer making, every layer thickness is 90-100mm, and the rubble of lower level floor embeds element soil
In；
S5, making geogrids layer: point two-layer making, first making steel plastic geogrid, repave stone powder levelling；
S6, making reinforced concrete floor: in described geogrids layer, in pile for prestressed pipe assembling reinforcement weld around shape
Becoming tiling grid shape bar-mat reinforcement, casting concrete on described bar-mat reinforcement and described pile for prestressed pipe, described concrete is by weight
Mark is poured formed in stone 10%-15%, cement 22%-35%, sand 30%-40%, the ratio of water 20%-30%；
S7, making anti-filter geotechnique's layer of cloth；Described anti-filter geotechnique's layer of cloth includes anti-filter geotextiles and covers anti-filter geotechnique
The geomembrane on cloth surface；
S8, pours bitumen layer；Divide three layers to pour, every layer of 5cm.
Wherein, rhone is less than original place roadbed 1.6m；Excavation target depth is 50mm.Calx and the weight fraction ratio of element soil
Example is 0.18:1, and the compactness of basic unit is 90%.The element soil doping levelling grinding compacting of Calx of basic unit, significantly reduces element soil
Water content.Place pile for prestressed pipe, improve the bearing capacity of roadbed.Blotter by cobble or particle size range 30～40mm broken
Stone rolls laying and forms, making blotter, further increases the bearing capacity of roadbed.Stone in stone powder, stone powder, white
Ash particle, the weight fraction ratio of miscellaneous soil are 42:37:11:10, repave stone powder levelling after making steel plastic geogrid, aging resistance,
Oxidation susceptibility, can the corrosion of the adverse circumstances such as acid and alkali resistance, salt, there is stronger bearing capacity.Good the breathing freely of anti-filter geotextiles
Property and water penetration, make current pass through, and the soil particle that effectively dams, fine sand, little building stones etc., to keep the steadiness of roadbed.
Comparative example
The roadbed construction method of the present invention is compared with comparative example 1 and comparative example 2 construction method, such as table 1 institute
Show:
Table 1 construction technology and parameter compare
From above-mentioned table 1, in the roadbed construction method of present invention offer and work progress, parameters ratio sets
