The present invention relates to the technical field of construction, more particularly to a kind of air bubble mix light-textured soil is in the filling construction method of the newly-built road in flat country.Construction site, placement, commissioning device are cleared up first；The match ratio index of debugging air bubble mix light-textured soil is required according to road construction；In construction position excavation pit, pour substrate and be fully compacted；Panel basis is poured, and lays panel is installed after blotter；Subsiding crack is set to close mould, fixed reinforced mesh；Pour air bubble mix light-textured soil；Pre-hardening rear top surface covering curing is poured；All pour light soil top surface after completion and re-lay waterproof geotextiles, carry out backfill construction in groove.Conventional earth and stone material is replaced from air bubble mix light-textured soil, because unit weight is lighter, has higher-strength after mitigating load, and air bubble mix light-textured soil hardening.Both sides traffic aisle can be set on ground, solve the problems, such as channel stagnant water, and top can also be filled using air bubble mix light-textured soil, because the unit weight of air bubble mix light-textured soil is low, and caused sedimentation is small.
Description
Technical field
The present invention relates to the technical field of construction, more particularly to a kind of air bubble mix light-textured soil are newly-built in flat country
The filling construction method of road.
Background technology
Plains region physical features is flat, broad view, and basic farmland proportion is higher, and carrying out highway in this region builds
If being the necessary substantial amounts of arable land of occupancy, because region of no relief village is intensive, populous, road network is interlaced, and existing flat land
Area's highway is generally that original ground is built.Original place, which is built, has following some problems：1st, the ponding that both sides resident traffic aisle is present oozes
Water problems, pitch problems and settlement issues；2nd, both sides of highway Drainage Design problem；3rd, highway blocks local Problems of Water Conservancy.Although
More farmland issue can be taken by raising roadbed and reducing highway, but is existed and fetched earth difficult and can increase the bearing capacity to ground
It is required that, and newly-built, enlarging highway faces expropriation of land hardly possible, and removal expense is high, hinder the traffic such as both sides of highway personnel, livestock, equipment
The problems such as dealing.
Existing highway construction is all the land type and structure according to project region, emphasis avoid basic farmland and
The sensitizing ranges such as high yield good farmland, select rational pouring construction method, are the most basic demands of newly-built road.
The content of the invention
The technical problems to be solved by the invention, which are to provide, can mitigate load and with the one of advantages of higher compressive strength and rigidity
Plant filling construction method of the air bubble mix light-textured soil in the newly-built road in flat country.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of air bubble mix light-textured soil is newly-built in flat country
The filling construction method of road, S1：Construction site is cleaned out and flattened, the relevant device of light soil stirring, debugging is laid
Equipment；
S2：The match ratio index of debugging air bubble mix light-textured soil is required according to road construction, the match ratio index includes
Wet density, fluidity and compression strength；
S3：In construction position excavation pit, pour substrate and be fully compacted；Panel basis is poured in substrate, and is laid broken
Panel is installed after stone bed course；
S4：Subsiding crack is set to close mould in foundation ditch, opsition dependent fixes reinforced mesh；
S5：Air bubble mix light-textured soil is poured in foundation ditch；
S6：Pour and poured the top surface covering curing of the air bubble mix light-textured soil of completion after initial set；
S7:Light soil top surface after completion is all poured by form of fracture and re-lays waterproof geotextiles, is then carried out in groove
Backfill construction.
Further：In the S2 unit weight grade of air bubble mix light-textured soil be W3~W15, strength grade be CF0.4~
CF25, fluidity is 180mm ± 20mm.
Further：Multiple compacting operation is carried out in the S3 when pouring substrate.
Further：The single of air bubble mix light-textured soil pours 0.8 meter of thickness in the S5.
Further：The step of S5-S7, is repeated successively from the bottom to top according to the depth of foundation ditch.
Further：The curing time of the S6 is more than 7d.
Based on above-mentioned technical proposal, the beneficial effects of the invention are as follows：
1st, conventional earth and stone material is replaced from air bubble mix light-textured soil, the more native stone backfill material of unit weight of air bubble mix light-textured soil
Low many of unit weight, it is smaller to earthen foundation active force, and have higher-strength after air bubble mix light-textured soil hardening, can be according to road
Design needs to carry out the suitable air bubble mix light-textured soil of selection proportioning.
2nd, both sides traffic aisle can be set on ground, solve the problems, such as channel stagnant water, and top is filled out using air bubble mix light-textured soil
Build, because the unit weight of air bubble mix light-textured soil is low, caused sedimentation is small.
3rd, unit weight is light, and excessive pressure will not be produced to ground, relatively low to foundation requirement.
4th, short time limit, easy construction saves time cost.
5th, road surface will not ponding, both sides of the road draining is easy.
Brief description of the drawings
Fig. 1 is a kind of method stream of the air bubble mix light-textured soil of the invention in the filling construction method of the newly-built road in flat country
Cheng Tu；
