Description
Technical field
The present invention relates to a kind of existing barricade section roadbed spelling money and increase structure, particularly relate to existing barricade section roadbed spelling width and add
The construction method of high structure.
Technical background
Along with economic development, rural economy was continuous progressive in recent years, and improving constantly of people's living standard makes
People are more and more higher to the requirement of quality of life.Road belongs to one of basic facilities of people's go off daily, in order to
Guarantee that people go on a journey is the most comfortable convenient.When many built roads are built, social economy's level, technical merit and construction are managed
The restriction read, has quite a few the most not adapt to the volume of traffic and increases and the requirement of social development.Reorganization and expansion to existing road
Just become the another solution outside newly-built road, road construction occupies increasingly consequence.Changing expansion
It is frequently encountered roadbed in building and spells wide problem.
Roadbed uses the wide technology of spelling to be directly connected to the normal pass of whole subgrade settlement and road, from conventional Engineering Projects
Understand, if new-old concrete bond spelling width position processes the bad differential settlement phenomenon that easilys lead to and occurs, and then produce longitudinal splitting
Seam, to such an extent as to cause lot of unstable factor for transportation.Therefore to widen section lay time, new-old concrete bond to be strengthened
The combination at position, the most just can increase the shear resistance of binding site so that the differential settlement that new-old concrete bond occurs obtains
With stable, in order to avoid new subgrade settlement is corrupted to old road base.Roadbed needs to remove the gear of former roadbed bank protection in spelling wide work progress simultaneously
Wall, this measure is likely to result in landslide, needs again new roadbed to be put slope after roadbed pile driving construction completes simultaneously, occupies a large amount of
Land resource.Being left intact under the bed course of new and old roadbed stage disk bottom, single bed course is likely to result in pad in the past
The sliding of layer.
In consideration of it, for new and old roadbed settlement issues, roadbed such as occupies cultivated land at the construction Difficulties, needs invention one at present badly and executes
Work speed is fast, and construction quality is good, and the existing barricade section roadbed economized the land resource is spelled width and increased construction method.
Summary of the invention
It is an object of the invention to provide a kind of existing barricade section roadbed spelling width and increase structure and construction method.
For achieving the above object, present invention employs techniques below scheme:
A kind of existing barricade section roadbed is spelled width and is increased structure, mainly includes that cast-in-situ bored pile, column, Bars In Poured Concrete Slab, L-type are prefabricated
Plate, cellular concrete, reinforced mesh, former barricade, former embankment, step etc., it is characterised in that cast-in-situ bored pile top arranges column
Platform, column platform pours column；Arranging Bars In Poured Concrete Slab on former barricade and column, Bars In Poured Concrete Slab outer rim arranges non-slipping block；L-type precoated plate sets
Put to coordinate to support on Bars In Poured Concrete Slab and form stepped slope structure；Pour cellular concrete on Bars In Poured Concrete Slab and bar-mat reinforcement is successively set
Sheet.
One layer of upper berth, top layer, ground sand-gravel cushion around described cast-in-situ bored pile, sand-gravel cushion arranges rhone.
Described drain pipe one end is arranged in sand stone layer and arranges filter screen.
Described column top arranges bearing.
Reserved hole slot and bar-shaped trough on described Bars In Poured Concrete Slab.
Described L-type precoated plate is with draw-in groove, and adjacent L-type precoated plate joggle is together.
It is step that described former side slope of embankment is rested and reorganized, and every layer of step is provided with one layer of reinforcing bar with pouring of cellular concrete
Mesh sheet.
Described L-type precoated plate surface covers backfill soil and afforests.
Described existing barricade section roadbed is spelled width and is increased the construction method of structure, it is characterised in that comprise the following steps:
1) former side slope of embankment is rested and reorganized: former barricade is motionless, step excavation on former side slope of embankment；
2) lower support structure construction: after bored concrete pile intensity hole to be drilled reaches design requirement, on every cast-in-situ bored pile top
Portion installs template and pours pylon, then backfills sand-gravel cushion and arranges rhone, sets up falsework and spread on sand-gravel cushion
If end template, shored by regulation and be adjusted to end template specify position, finally carry out Bars In Poured Concrete Slab and pour；
3) L-type precoated plate is installed: the most successively installing L-type precoated plate, neighbouring L-type precoated plate joggle is one
Rising, bottom arranges support, and precoated plate is installed by the superiors, backfills one after all precoated plates install on the step formed
Divide backfill soil；
4) cellular concrete pours: first between step bottommost and Bars In Poured Concrete Slab backfill one layer of sand-gravel cushion, then by
Layer carries out cellular concrete and pours and successively lay reinforced mesh, after cellular concrete intensity reaches design requirement, carries out new
Road surface, guardrail and gutter construction, finally cover backfill soil at new side slope of embankment upper surface and plant green plants.
The present invention has following feature and a beneficial effect:
(1) hole drilling bored concrete pile and pylon construction, and pouring reinforcement concrete plate on pylon are drawn outside roadbed side slope, existing
Water and on plate, pour cellular concrete, then earth-covering greening, this form of construction work economy environmental protection again.
(2) template that L-type precoated plate joggle pours as cellular concrete together, can prevent as side slope step again
Protect.
(3) old road dike is strengthened linking together by reinforced mesh with new embankment.
(4) existing road is widened, it is not necessary to remove old barricade, old barricade is spelled as roadbed wide structure one
Point.
