Abstract
The invention discloses a kind of compacted construction methods of high-fill roadbed, comprising the following steps: (1) prepares backfill material；(2) backfill region is cleared up, then carries out the unwrapping wire of backfill layer；(3) backfill material is backfilled according to unwrapping wire, backfill carries out compacting point setting-out with pulverized limestone afterwards in place, and each compacting point is rammed 3-4 times；(4) it is whole to backfill material once rammed after, expect that pit caused by ramming mend using identical backfill and fill out, benefit is layouted again after tamping reality, carry out it is secondary rams, secondary ram needs all to ram once time filler surface；(5) (2) to the step (4) that repeats the above steps successively is backfilled, until designed elevation.The present invention uses the compacted technique of strong rammer, shortens the backfill duration, and roadbed backfill is high-quality, reduces construction risk, solves the problems, such as that backfill must could be completed using large-scale compacting equipment, has high economic benefit.
Description
Technical field
The invention belongs to highway construction technology fields, and in particular to a kind of compacted construction method of high-fill roadbed.
Background technique
In today of highway in China construction high speed development, high embankment embankment is still in addition to building a bridge across cheuch
One of main means.Guarantee marching into the arena for heavy compacting equipment since the backfill (the especially construction backfill of early period) of high embankment is extremely difficult
Operation can only successively be backfilled using middle-size and small-size compacting equipment, be occurred since compactness deficiency will cause the road after completion
Biggish sedimentation and deformation.Disease is run to reduce later period road, is usually taken postpones pavement construction by the soil body in gravity in the past
Natural consolidation under effect settles or reserves the mode of secondary repairing to guarantee the running quality after engineering is formally handed over.But it is existing
Construction period shortening and postrun heavy traffic pressure, it is secondary perfect to carry out to have extended the duration, because
This, is badly in need of a kind of quick tamping road bed method of energy.
Summary of the invention
The technical problems to be solved by the invention are in view of the above shortcomings of the prior art, to provide a kind of high-fill roadbed
Compacted construction method, it can be quickly tamping road bed using middle-size and small-size equipment, reduces the probability of subgrade deformation.
The technical scheme adopted by the invention is that: a kind of compacted construction method of high-fill roadbed, comprising the following steps:
(1) prepare backfill material, cannot be native containing fertile soil, house refuse in the backfill material of selection, it cannot contain in mud
It is weeds, several；
(2) backfill region is cleared up, then carries out the unwrapping wire of backfill layer；
(3) backfill material is backfilled according to unwrapping wire, backfill carries out compacting point setting-out, each compacting with pulverized limestone afterwards in place
Point is rammed 3-4 times；
(4) after once being rammed to backfill material entirety, expect that pit caused by ramming is mended using identical backfill
It fills out, benefit is layouted again after tamping reality, and progress is secondary to be rammed, and secondary needs of ramming all ram once time filler surface；
(5) (2) to the step (4) that repeats the above steps successively is backfilled, until designed elevation.
Preferably, the spacing in length and breadth of adjacent compacting point is 5m in step (3).
Preferably, the work of ramming in step (3) is carried out from road both lateral sides edge to road-center.
Preferably, the height of every layer of backfill layer is 3m-4m.
Preferably, being equipped with articulamentum between adjacent two layers backfill layer, the articulamentum includes the coagulation of 70%-80%
Soil, the rubble of 10%-15%, surplus are pitch.
The present invention uses the compacted technique of strong rammer, shortens the backfill duration, and roadbed backfill is high-quality, reduces construction wind
Danger solves the problems, such as that backfill must could be completed using large-scale compacting equipment, has high economic benefit.
Specific embodiment
Below in conjunction with specific embodiment, invention is further described in detail.
Embodiment
The compacted construction method of high-fill roadbed provided in this embodiment, comprising the following steps:
(1) prepare backfill material, cannot be native containing fertile soil, house refuse in the backfill material of selection, it cannot contain in mud
It is weeds, several；
(2) backfill region is cleared up, then carries out the unwrapping wire of backfill layer；
(3) backfill material is backfilled according to unwrapping wire, backfill carries out compacting point setting-out, adjacent compacting with pulverized limestone afterwards in place
The spacing in length and breadth of point, with dipstick metering lifting rope length, slings weight according to the sling height being calculated using ramming for 5m, then
Release makes weight fall naturally, and each compacting point needs to ram 3-4 times, to guarantee to ram dense effect, while ramming work
It is carried out from road both lateral sides edge to road-center；
It needs to measure original ground absolute altitude before ramming, often rams and once record the elevation after this is rammed, calculate differential settlement, when
Ramming times should be increased for the third time or when ramming submergence depth for the 4th time greater than specified value；
(4) after once being rammed to backfill material entirety, expect that pit caused by ramming is mended using identical backfill
It fills out, benefit is layouted again after tamping reality, and progress is secondary to be rammed, and secondary needs of ramming all ram once time filler surface；
(5) (2) to the step (4) that repeats the above steps successively is backfilled, until designed elevation, the height of every layer of backfill layer
For 3m-4m, and articulamentum is equipped between adjacent two layers backfill layer, the articulamentum include 70%-80% concrete,
The rubble of 10%-15%, surplus are pitch.
The above is only the preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, any
The transformation and replacement carried out based on technical solution provided by the present invention and inventive concept should all be covered in protection model of the invention
In enclosing.
