Refering to fig. 1 to Fig. 2.
Present embodiments provide a kind of method for manufacturing resonant rubbilizing composite base 200.Manufacture provided by the invention is altogether
The method of vibration rubblization composite base 200 can be used for the construction of various roads, however, it is preferred to be used to form in asphalt road
Face.
The manufacturing method of resonant rubbilizing composite base 200 the following steps are included:
Step S101, lean concrete is poured on roadbed 101 to form lean concrete layer 102, and in lean concrete layer
The vibration insulation 103 for stopping resonance wave transmitting is formed on 102.
Wherein, the material for constituting vibration insulation 103 can be the slurry of cement and aggregate chips.Better vibration isolation material can also be used
The bed of material.
Lean concrete layer 102 is to pour to solidify using lean concrete.Lean concrete (Lean Concrete, LC) is
A kind of material being formulated by thick, fine aggregate and certain cement and water.Its intensity is much higher than two ash stability pellet, cement
The semi-rigid sub-base materials such as stabilization gravel.Lean concrete strength and stiffness with higher, water stability is good, erosion resistibility is strong.
For lean concrete since cementitious matter content is few, voidage is generally large, is conducive to the discharge of interfacial water.Lean concrete can mitigate soil matrix
Inhomogeneous deformation, the adverse effect of road pavement can be eliminated.In addition, lean concrete can also utilize the water for the stall production that occupies a narrow space
Mud, it is possible to use the locality of substandard gathers materials.Lean concrete layer 102 can be used as permanent protection and supporting structure, due to this
The layer position of layer is underlying, itself will not generate drying shrinkage and temperature contracting cracking and damage.
The vibration insulation 103 formed on lean concrete layer 102 is mainly constructed and carries out in resonance fragmentation processing to subsequent
Resonance wave stopped or blocked.It can damage to avoid resonance wave to lean concrete layer 102 by vibration insulation 103.It should
, it is noted that the setting of vibration insulation 103 is to be required and be set based on technique, substantially and non-formation composite construction layer
Necessary structure sheaf.
Resonate crushable layer and 102 being integrally formed of lean concrete layer in the above manner, so as to the compatible drip being laid with
Green surface layer structure, it is ensured that asphalt surface course will not be damaged because of fatigue cracking.
Step S102, the casting concrete on vibration insulation 103 forms concrete slab.
Described pours the concrete adoption of existing standard joints cement sheet metal forming to form concrete slab for passing through.All
Concrete slab is constituted after hardening.Used concrete can be commerical ready-mixed concrete material, and general not by pavement concrete
Material is as preferred material.Wherein, there is the commerical ready-mixed concrete material resistant Compressive Strength certain restriction to require, and road surface
Concrete material all has certain restriction requirement to compression strength and flexural strength.Therefore, in cast-in-place concrete, commodity are mixed
Solidifying soil material has better advantage, for example, price is lower.
In resonant rubbilizing composite base 200 proposed by the invention, formed the concrete grade of concrete slab in C30 and
Above, lean concrete layer marked as C10~C15, can arbitrarily be selected in signified scope by this field designer.
In addition, the thickness based on adjustment resonant rubbilizing composite base 200 is mixed with meeting the requirement of Pavement Design, construction
The thickness of concrete board can be adopted as any value of 18~24cm.
It can be in lean concrete layer table before manufacturing vibration insulation 103 on lean concrete based on the demand of some constructions
Face is laid with isolation film, then remanufactures vibration insulation 103.In other words, the method for vibration insulation 103 is formed on lean concrete layer 102
Include: to be laid with isolation film in lean concrete layer 102, then remanufactures vibration insulation 103.In some examples, vibration insulation 103 can be adopted
With the slurry of cement and aggregate chips.Preferably, the slurry has self-leveling, to reduce its difficulty of construction.
Step S103, carrying out resonant rubbilizing processing to concrete slab makes concrete slab be broken, to obtain resonance rubble
Change layer 104.
After concrete slab forms hardening, by resonant rubbilizing equipment, process, it is made to be broken, to be formed
Resonant rubbilizing layer 104.Resonant rubbilizing equipment, technique can using technique known for inventor or it is current it is general by the way of
To implement.
More preferably, it is oblique that concrete slab is formed after resonant rubbilizing is handled crushed stone constitutes top embedded squeezing, lower part
The structure of interlocking, and embedded squeezing partially away from roadbed 101, the part of oblique interlocking is adjacent to roadbed 101.Make resonant rubbilizing layer
104 have upper layer embedded squeezing, the structure of the oblique interlocking of lower layer, can play the purpose of stabilizing cement concrete material structure sheaf, make to resonate broken
Petrochemical industry layer 104 is more stable.The rock-steady structure of oblique interlocking, makes its own not generate internal stress, and chance external force only uniformly synchronizes micro-
Deformation, and without differential settlement phenomenon.In some instances, 104 top Cement Concrete pellet layer of resonant rubbilizing layer is that water can seep
Permeable layers play the role of suction and put tidewater, pavement structure is made not generate water damage.Cement Concrete oblique interlocking layer in lower part is the impermeable infiltration of water
Layer, plays impermeable role between the body upper and lower level of road, prevents Moisture Damage.
Resonant rubbilizing layer 104 and asphalt surface course 105 belong to flexible layer property, and the pellet size of the two contact surface is close,
It can engage each other closely, be formed and coupled without shiny surface, do not set any adhesion coating without sliding phenomenon；And the thickness of repaving asphalt coat
Degree need to only meet the thickness of the intensive force area of road deck, can also reserve that repaving asphalt coat extends and uses the longevity again using the later period
The design of life.
Resonance is broken to be completed using resonance crusher device.The frequency of resonance crusher device is in 44Hz~50Hz, amplitude
2Cm vibrates tup with frequency low-amplitude and taps concrete slab, and resonance amplitude below concrete slab tup is made to reach maximum value, concrete
Because oblique shear power makes top plate body be separated into natural grading Cement Concrete pellet, lower part plate body generates oblique interlocking and splits intralamellar part
Line simultaneously has stronger bearing capacity, as vibration regularly extends rapidly, until cement plate boundary.Since impact force is smaller,
And crackle only expands to boundary, so in base lean concrete layer 102 and roadbed 101 without any damage.
Currently, some so-called flexbile bases are also used in the prior art.Its base mainly uses graded broken stone
It constitutes.The construction of graded broken stone layer is that the rolling by stone material, the embedded squeezing to rubble closely form；Complex manufacturing technology, excessively according to
The experience and manufacturing technology level for relying people are extremely difficult to the embedded squeezing " stablized " and form the purpose being utilized；Its expenditure of construction is also special
It is not high.
It is suggested by a kind of above-mentioned resonant rubbilizing composite base 200 of manufacturing method, and resonant rubbilizing composite base
Layer 200 includes: lean concrete layer 102, vibration insulation 103 and resonant rubbilizing layer 104.Lean concrete layer 102, vibration insulation 103
And resonant rubbilizing layer 104 is successively arranged.
In some optional examples, resonant rubbilizing composite base 200 is with a thickness of 50cm.Certainly, resonant rubbilizing is compound
The thickness of base 200 neatly can also be adjusted and be changed according to the actual needs.For example, adjustable lean concrete layer
The thickness of thickness and concrete slab.
As a kind of use-case, a kind of asphalt pavement structure 100 is additionally provided in the embodiment of the present invention.Asphalt pavement structure
100 include: that the method according to above-mentioned manufacture resonant rubbilizing composite base 200 being formed on roadbed 101 is fabricated
