Description
Technical field
The utility model relates to civil engineering, and particularly ground engineering is made in the control of mountain road Debris Flow or the backfill of mountain road cheuch section.
Background technology
In China, mountain area cheuch is extremely grown, when the highway construction of building is passed through cheuch, conventionally pass through with the form of bridge, in the time thering is Debris Flow harm, need to pass through with Longspan Bridge, if but the line elevation of cheuch two ends road is when lower, the mud-rock flow danger of cheuch section can not be eliminated, or when needing backfill cheuch to carry out mountain area, the cheuch district of crossing at existing path link makes when ground, need a kind of new mountain area cheuch path link to cross form of structure with head it off, and there is easy construction, safe and reliable, economic dispatch feature, and meet the requirement of environmental protection.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of mountain area cheuch backfill tunnel construction, has easy construction, safe and reliable, economic dispatch feature.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Cheuch backfill tunnel construction in mountain area of the present utility model, is characterized in that it comprises: fill concrete basis, and longitudinally build in cheuch substrate and stablize on Rock And Soil along road; Tunnel structure body, is arranged at top, fill concrete basis; Backfill buffering filling body, fills in fill concrete basis and tunnel structure body two ends; Drainage channel, is arranged at ditch valley portions, is communicated with the backfill buffering filling body of both sides, fill concrete basis; Backfill topping, fills in backfill buffering filling body and tunnel structure body top; Make ground filling body, fill in backfill buffering filling body and tunnel structure body top.
The beneficial effects of the utility model are, efficiently solve mountain road cheuch section debris flow or ground problem is made in the cheuch district backfill of crossing at existing path link, and have easy construction, safe and reliable, economic dispatch feature, and meet the requirement of environmental protection.
Brief description of the drawings
This manual comprises following two width accompanying drawings:
Fig. 1 is the schematic cross-sectional view of the utility model mountain area cheuch backfill tunnel construction;
Fig. 2 is the drainage channel structural representation of the utility model mountain area cheuch backfill tunnel construction;
Member shown in figure, toponym and corresponding mark: fill concrete basis 1, tunnel structure body 2, backfill cushion filling body 3, drainage channel 4, concrete foundation 41, spilled water hole 42, backfill rubble 43, permeable geotextiles 44, backfill topping 5, make ground filling body 6.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, cheuch backfill tunnel construction in mountain area of the present utility model comprises: fill concrete basis 1, and longitudinally build in cheuch substrate and stablize on Rock And Soil along road; Tunnel structure body 2, is arranged at 1 top, fill concrete basis; Backfill buffering filling body 3, fills in fill concrete basis 1 and tunnel structure body 2 two ends; Drainage channel 4, is arranged at ditch valley portions, is communicated with the backfill buffering filling body of both sides, fill concrete basis; Backfill topping 5, fills in backfill buffering filling body 3 and tunnel structure body top 2; Make ground filling body 6, fill in backfill buffering filling body 3 and tunnel structure body 2 tops.
Fill concrete basis 1 is as the carrying basis of tunnel structure body 2, and ensures the monolithic stability of tunnel structure body 2 and control its settling amount.Tunnel structure body 2, as passing road, can be avoided the harm of mud-rock flow to highway construction, or avoids cheuch backfill to make ground and affect existing road.Backfill buffering filling body 3, protection fill concrete basis 1 and tunnel structure body 2, increase its stability and the percussion of avoiding mud-rock flow.Drainage channel 4 is arranged at ditch valley portions, is communicated with the backfill buffering filling body of both sides, fill concrete basis, discharges the underground ponding of fill concrete basis 1 backer's side, ensures the long-term stability of total body.Backfill topping 5 avoids mud-rock flow directly to impact fill concrete basis 1 and tunnel structure body 2, and sapping backfill buffering filling body 3.Ground filling body 6 backfill cheuches are made in utilization, form and make ground using area.This structure efficiently solves mountain road cheuch section debris flow or ground problem is made in the cheuch district backfill of crossing at existing path link, and has easy construction, safe and reliable, economic dispatch feature, and meets the requirement of environmental protection, has wide popularizing application prospect.
With reference to Fig. 1, described fill concrete basis 1 is longitudinally built in cheuch substrate and is stablized on Rock And Soil along road, its depth of burying need meet the deformation requirements of top tunnel structure body 2 and the pressure control requirement of top filling body, and ensures from have enough safeties under Upper Structure.Between described tunnel structure body 2 and fill concrete basis 1, need to take shearing resistance measure, can not occur and fill concrete basis 1 between shear strain, its structural strength can be resisted top and be filled native load.The described ground filling body 6 of making adopts in the time that backfill tunnel construction is made ground for backfill, and its filled height is determined according to making ground absolute altitude.Described backfill buffering filling body 3 is answered closely knit filling, and coefficient of consolidation is not less than 0.8.Described backfill topping 5 adopts mortar flag stone to fill when preventing and treating mud-rock flow when backfill tunnel construction, and thickness is not less than 0.5m.
Described drainage channel 4 arranges together every 10～20m in ditch valley portions, its sectional dimension is wide high 1.0～2.0m, longitudinal gradient is not less than 4%, with reference to Fig. 2, described drainage channel 4 is made up of the backfill rubble 43 that has the concrete foundation 41 in groove type cross section and fill in the inner, on the sidewall of concrete foundation 41, spilled water hole 42 is offered at interval, lays permeable geotextiles 44 at the end face of backfill rubble 43 and concrete foundation 41.When by 1 section, fill concrete basis, concrete foundation 41 adopts reinforced concrete structure form.
Some principles of the above the utility model mountain area cheuch backfill tunnel construction that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore the corresponding modify being likely utilized every and equivalent, all belong to the scope of the claims that the utility model is applied for.
