Description
Technical field
The utility model relates to a kind of pavement crack preparing structure, and particularly a kind of asphalt concrete pavement crack preparing structure belongs to maintenance of surface engineering field.
Background technology
Under factor affecting such as differential settlement, frost heave, ground surface material contraction, heavy traffic, overload, asphalt concrete pavement easily produces in length and breadth to the crack, after the asphalt concrete pavement crack produces, should in time be handled, hazardous substancess such as anti-sealing are invaded, and influence the normal use of road and application life.In many diseases of asphalt concrete pavement, the crack is the most general, the topmost disease form of asphalt concrete pavement, and is comparatively remarkable to durability, the globality influence of flexible pavement.
Origin cause of formation difference according to the crack, the asphalt concrete pavement crack can be divided into three types: (1) load type crack mainly is under the vehicular load effect, and the tensile stress of semi-rigid type base bottom is during greater than the tensile strength of structure, to ftracture in the basic unit bottom, and progressively reflex to upper layer; (2) non-load type crack mainly is low temperature shrinkage crack and the temperature fatigue crack based on thermal cracking, and because construction technology is improper or the crack of the defective generation of material; (3) settlement crack, mainly the differential settlement by embankment, roadbed behind the worker causes.The form of pavement crack is usually expressed as transverse crack, longitudinal crack, check crack and reflection crack etc.
The globality of road structure not only can be destroyed in the asphalt concrete pavement crack, and can reduce the performance of ground surface material, and the crack becomes the rainwater infiltration passage simultaneously, easily causes the vicious circle of pavement disease, shortens the application life on road surface.Therefore, engineering circle is attached great importance to the punishment problem of asphalt pavement crack, has some punishment methods at present, and wherein using the most general punishment method is joint filling method and cementation of fissures method.The joint filling method is to utilize slot-cutting machine earlier with pitch crack grooving, pours into enclosed material again, generally is applicable to and repairs width less than the crack of 20mm.Cementation of fissures method and joint filling method major different are the preparation before the cementation of fissures and use the material of the cementation of fissures different, be mainly used in crack more serious road surface, particularly width greater than the crack of 20mm., crack irregular road surface serious for road surface breakage, usually adopt methods such as adding after heat mending, shop layer cover or the milling machine milling heavily the shop to repair, but because these punishment measures are difficult to effectively solve problems such as deep layer crack reflection, ground open fire infiltration, repair the possibility that primary fissure seam place, road surface ftractures again after finishing and surpass 85%.
In sum, existing asphalt pavement crack punishment method remains problems such as recovery technique crash rate height, structure durability difference, needs at present that a kind of impermeability of invention is good, durability is strong, validity is remarkable, original road is influenced little crack, novel asphalt rigid pavement preparing structure badly.
Summary of the invention
It is convenient, impervious good that the purpose of this utility model is to invent a kind of construction, can effectively stop the crack further to be carried out, and has the asphalt concrete pavement crack preparing structure of better economic technology benefit.
In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:
A kind of asphalt concrete pavement crack preparing structure is characterized in that along the pavement crack length direction, excavates step slot, and opens V-shaped groove along fracture strike in basic unit and subbase at top-down upper layer, middle surface layer, following surface layer; Asphalt reperfusion glue forms the pitch glue cementation of fissures in the V-shaped groove; At the bottom of step slot, spray mulseal and form oil reservoir; On the V-shaped groove top seam with holes top steel plate is installed, and is adopted rivet to fix; After box cut inwall, saturating oil reservoir spray sticking oil reservoir, lay surface layer repair layer, reinforcement net sheet, middle surface layer repair layer, geotextiles, upper layer repair layer down successively, and adopt the mulseal edge sealing.
Aforesaid asphalt concrete pavement crack preparing structure is characterized in that rivet is quincunx or square even interval at seam top steel plate and arranges that rivet embeds basic unit's length and is no less than 1/2 of groundwork thickness.
Aforesaid asphalt concrete pavement crack preparing structure is characterized in that reinforcement net sheet places down surface layer repair layer top, surface layer repair layer top in the middle of geotextiles is positioned at, and reinforcement net sheet and geotextiles are all laid at the full width of cloth of bottom land.
The utlity model has following characteristics and beneficial effect:
(1) in basic unit and subbase, excavate V-shaped groove and asphalt reperfusion glue along fractuer direction after, adopt seam top steel plate to bind, and adopt rivet to fix, further carrying out and occurring repeatedly of crack can be effectively avoided in crack joint filling and punish effectively.
(2) setting of reinforcement net sheet and geotextiles, for the crack preparing structure is provided with 2 road anticracking reinforcement measures, the design of collaborative mulseal edge sealing can effectively improve the globality, durability, impermeability of crack preparing structure etc.
(3) setting of each surface layer step slot is aided with sticking oil reservoir and saturating oil reservoir, both can effectively strengthen the globality of preparing structure, can stop the reflection of basal crack again, has strengthened the globality of preparing structure etc. simultaneously.
