Description
Technical field
The invention belongs to technical field of road engineering, and in particular to a kind of cement concrete road structure layer sewerage system and its apply
Work method, applied to the driveway of cement concrete pavement, such as the highway of cement concrete pavement, the urban road of cement concrete pavement, cement
The backroad etc. of concrete topping.
Background technique
Between Cement Concrete plate layer and base interfacial water (" interfacial water " refers in particular in text: Cement Concrete plate layer and base it
Between occluded water and base layer structure top occluded water) pavement structure can not be discharged, cause cement concrete pavement damage
One of the main reasons.The interfacial water for causing cement concrete pavement to destroy, the predominantly occluded water on road surface and Cement Concrete plate side
The occluded water of edge, the water formed by sleet, cleaning road surface water etc. form.Under the action of traffic load, interfacial water is easily made
Situations such as isolating at base material, being lost, lead to loosening, the plat-bottom escape of Cement Concrete plate, is embodied in cement concrete slab and goes out
Now diseases such as crack, reticulate pattern crack, purt mud, faulting of slab ends in length and breadth.
Currently, for pavement damage caused by interfacial water, lack feasible early prevention (" early prevention " refers in particular in text:
In the construction stage, interfacial water is excluded using job facilities), (" subsequent to administer " refers in particular in text: using rank based on to administer afterwards
Section, repairs road disease), in other words, existing cement concrete pavement design and construction do not consider to exclude interfacial water,
In use process after disease occurs in road surface, then repair.This thinking administered afterwards, although eliminating early prevention
Work, but the cost paid is very big;The disease for repairing cement concrete pavement, will not only spend a large amount of manpower and material resources, but also
Maintenance construction easily leads to traffic congestion, caused by social economy's cost be difficult to estimate.
Above-mentioned deficiency still has and is worth improved place.
Summary of the invention
Present invention aims to overcome that above-mentioned the deficiencies in the prior art, use a kind of novel work in cement concrete pavement construction
Journey facility belongs to the early prevention more particularly to a kind of new type water of interfacial water to exclude the interfacial water of cement concrete road structure
