Description
Technical field
This utility model relates to a kind of building highway field, particularly to a kind of laterite pellet of rubble of mixing as basic unit
Pavement structure.
Background technology
Through street and trunk roads, extra heavy and heavy traffic road, toll plaza and neighbouring expansion joint (E.J.) or 3 contractings of free end
All can arrange dowel steel in seam, its effect is to transmit traffic load between two block road plates and prevent faulting of slab ends, increases adjacent mixed
Stress Transfer between solidifying soil block, to prevent concrete road surface local pressure from causing more greatly concrete road surface differential settlement, is transmitted
Stress makes the common stress of adjacent concrete block, and existing pavement structure drainage is poor, makes the internal hydrops in road surface cause inside road surface
Structural failure, driving a vehicle for a long time in road surface can be in basic unit's generation crack, and basic crack produces impact to surface layer makes surface layer deform, meanwhile,
Traffic load is excessive it cannot be guaranteed that automotive safety under the conditions of all-weather, comfortable, at a high speed, effectively run, and can cause road occupation
Reduced lifetime.
Utility model content
The purpose of this utility model is to provide a kind of safe and reliable, is unlikely to deform, it is ensured that automotive safety under the conditions of all-weather,
Comfortable, at a high speed, effectively run, what serviceability level was good mixes the laterite pellet pavement structure as basic unit of rubble.
To achieve these goals, the technical solution of the utility model is:
A kind of laterite pellet pavement structure as basic unit mixing rubble, including the base course set gradually from the bottom to top,
Bed course, basic unit and surface layer, and it is laid in the dowel steel of surface layer central part, between described basic unit and surface layer, connection is set
Layer, the bottom surface of described binder course arranges reinforcing bar stratum reticulare, and the end face of described basic unit, bottom surface are respectively provided with geotextiles, basic unit
Bottom arranges longitudinal draining sewer, arranges joint plate at the intermediate gap of surface layer, and the bottom of described dowel steel arranges " N " shape
Gripper shoe, described gripper shoe is fixed in surface layer by fixing nail, and the internal chiasma of gripper shoe arranges bracing piece, dowel steel
Mid portion fit plastic bushing, the termination point casing trap cap of dowel steel one end, dowel steel is fixed on support by standing screw
On plate, described standing screw is " U "-shaped.
Further, described draining sewer is positioned at the upper end of the geotextiles of basic unit bottom surface.
Further, described basic unit is the laterite pellet mixing rubble.
Further, described fixing nail is anchor studs.
This utility model is a kind of laterite pellet pavement structure as basic unit mixing rubble, and it has the beneficial effect that
The binder course that this utility model is arranged can be strengthened the common effect of surface layer and basic unit or reduce basic crack opposite
The impact of layer, the reinforcing bar stratum reticulare bottom binder course can play the effect of reinforcement, alleviate road surface load force, makes road surface bearing capacity become
By force；Geotextiles and draining sewer can effectively prevent the change of the pavement structure that hydrops causes inside road surface, use and mix rubble
Laterite pellet as basic unit, make that pavement strength is higher, compressibility is relatively low, make road surface be unlikely to deform；Plastics in the middle of dowel steel
Sleeve pipe is possible to prevent dowel steel to get rusty, and standing screw can play dowel steel location on the supporting plate and fixing double acting,
Internal chiasma in gripper shoe arranges bracing piece, can strengthen the stress of gripper shoe, makes gripper shoe stress strengthen, and alleviates driving lotus
Carry, it is ensured that automotive safety under the conditions of all-weather, comfortable, at a high speed, effectively run, increase Road Service Life.
