Description
Technical field
The present invention relates to the method building different kinds of roads, the soft soil roadbed method of particularly a kind of mountain skin stone process, it is suitable for
In building different kinds of roads on the soft foundations such as frozen soil, level of ground water height, spring soil, salt-soda soil.
Background technology
At present, China coast industrial base geological condition is complicated, usually occurs that frozen soil, level of ground water be high, spring is native, saline and alkaline
Multiple soft foundations such as ground, had both needed the longer duration using conventional Soft Soil Subgrade Treatment Method, required there is 12 as roadbed
The sedimentation of more than individual month just can carry out pavement construction, can not fundamentally solve subgrade stability sex chromosome mosaicism again, as earth roadbed in Calx
Contractility is big, easily ftracture, should not be used in moist section, and needs to waste substantial contribution.
As can be seen here, in order to overcome drawbacks described above present in conventional soft base processing method construction, seek one kind both economical
Can gather materials on the spot again, convenient construction, and the effective ways of coastal soft subgrade treatment can be solved in shorter time, be current edge
One very urgent task of marine products industry construction of base person.
Content of the invention
The present invention is directed to the defect of prior art, provides a kind of mountain skin stone to process soft soil roadbed method, this construction method is fitted
For various soft soil roadbed, effectively shorten the duration, fundamentally solve the stability problem of roadbed.
Realize this technical scheme below of above-mentioned purpose：
A kind of mountain skin stone processes soft soil roadbed method it is characterised in that comprising the steps：
A. soft soil roadbed clear table：Full width is down dug from original ground first, detects the mark after original ground absolute altitude and clear table at any time
Height, to ensure that ground eliminating impurities are clean and protect
Card filling-up thickness；Measure bottom width degree after clear table, to meet roadbed filling width, road
Place soil during the clear table of base and be more than 2m from clear table boundary；
B, surveying and locating：Lay double-direction control stake on the basis of SURVEYING CONTROL NETWORK, form 10*10m and control net, run into curved
It is encrypted at road, and mark the elevation after empty paving elevation and compacting；
C, particle diameter is transported to scene less than or equal to 60cm mountain skin building stones, then material is paved, shaping, roll, health preserving；Stand
Laying method is to be paved using man-machine cooperation, is first shakeout roughly with bull-dozer, then adopts land leveller essence flat, after land leveller
The group that paves of 10m fit on 3-5 people, timely treated aggregate non-uniform phenomenon;Using the rolling method that first quiet rear shake is quiet again,
The road roller speed of travel is 1.5-1.7km/h, first uses road roller static pressure 2-3 time, in place of finding out injustice, uses artificial filling-in, then
Roll 4-5 time with vibrated roller, finally adopt road roller static pressure 2-3 time;
D., after the completion of the first Rotating fields health preserving, carry out second layer structure sheaf construction：By the mountain calculating skin stone by design
Width, thickness shakeout, carry out again shaping, roll, health preserving.
D., after the completion of the first Rotating fields health preserving, carry out second layer structure sheaf construction：By the mountain calculating skin stone by design
Width, thickness shakeout, carry out again shaping, roll, health preserving.
Preferably, the coefficient of loose laying of empty paving elevation is 1.30, concrete numerical value determines according to test section.
Preferably, mountain skin stone filling-up thickness is more than or equal to 90cm.
Using technique scheme, compared with prior art, the soft soil roadbed intensity processing through mountain skin stone improves 3-5
Times, plastic deformation reduces 70%-80%.Frost resistance improves, and after enduring cold, degree of compaction is unchanged, and the coefficient of expansion reduces 60%-80%；Effectively
Accelerating construction progress, shorten the completion time of project, this construction method is applied to various soft soil roadbed, and can be used for moist section even
Roadbed be applied to water, effectively overcomes the differential settlement of roadbed, decreases settlement of subgrade cracking in useful life
Maintenance number of times, reduce late maintaining cost, decrease job site dust granules, reduce the ring in road construction
Border cost, ensures that workmen is healthy.
Brief description
Fig. 1 is road structure schematic diagram of the present invention：
In figure：Mountain skin stone 1, removes table soil thickness 2.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
Specific construction process of the present invention is as follows：
1. preparation of construction
Before present invention construction, mountain skin stone 1 is tested, material maximum particle diameter is not more than 60cm, exceed this part and buying
Ground is crushed；Coordinate control point and vertical control point are carried out in scene.
2. surveying and locating
The present invention lays double-direction control stake on the basis of SURVEYING CONTROL NETWORK, forms 10*10m and controls net, runs into corner
It is being encrypted, marking elevation after empty paving elevation and compacting with red paint.Coefficient of loose laying typically takes 1.30, and concrete numerical value is according to examination
Test section to determine.
3. soft soil roadbed clear table
Full width is down dug from original ground first, and removing table soil thickness 2 is 40-60cm, at any time detection original ground absolute altitude and clear
Absolute altitude after table, to ensure ground debris（As weeds, miscellaneous tree, humus）Remove clean and ensure filling-up thickness；Measure clear table
Bottom width degree afterwards, to meet roadbed filling width, will consider the gradient of side slope during the clear table of roadbed, place soil will from clear table boundary 2m with
On；
4. mountain skin stone transport
The mountain skin stone 1 meeting design requirement particle diameter is transported to scene using dump truck, during transport, carries out finished product protection,
Never allow heavy-duty truck transportation, prevent to drive over the speed limit, carry out security protection；Computed in advance unload following distance, then unloaded
Car, backfill, the shaping that paves, roll, health preserving；
5. backfill
Thickness is backfilled according to the different characteristics design mountain skin stone 1 of various roadbeds, thickness is more than or equal to 90cm.
6. pave shaping
The present invention is paved using man-machine cooperation, is first shakeout roughly with bull-dozer, then adopts land leveller essence flat, level land
The group that paves of 10m fit on 3-5 people after machine, timely treated aggregate non-uniform phenomenon.
7. roll
The present invention is using shaking rolling method quiet again after first quiet, it then follows first gently weigh afterwards, first slowly after overlapping former of fast, wheelmark
Then；The road roller speed of travel is 1.5-1.7km/h, and degree of compaction can suitably accelerate rolling speed after increasing, and round trip is one time,
First adopt road roller static pressure 2-3 time, in place of finding out injustice, use artificial filling-in, then roll 4-5 time with vibrated roller, finally
Using road roller static pressure 2-3 time.
8., after the completion of the first Rotating fields health preserving, carry out second layer structure sheaf construction：By the mountain calculating skin stone by certain
Width, thickness shakeout, carry out again shaping, roll, health preserving.
The present invention is applied to build advanced road and ordinary road, is particularly suited for coastal cities road foundation and once builds
The needs becoming.It can make, and China is wet, soft, freeze, saline and alkaline earth roadbed compaction quality and intensity are reached advanced world standards.
