Description
Technical field
The present invention relates to the repairing and strengthening of damaged concrete road slab, particularly relate to the repair structure of concrete road faceplate panels and the restorative procedure of damaged concrete road slab.
Background technology
By the end of the year 2011, national total mileage of highway will reach 410.64 ten thousand kilometers, and that builds up has paved road 210.34 ten thousand kilometers, and wherein, Portland cement concrete pavement 151.21 ten thousand kilometers, occupies 71.9% of paved road sum.Cement concrete pavement refers to cement concrete to be the road surface that main material does surface layer, be called for short rigid pavement, also known as rigid pavement, Common Concrete Pavement is except seaming zone and subrange (edge or corner), not configuration reinforcement, also known as plain concrete road surface.
But, along with the propelled at high velocity of modernization construction, the traffic volume constantly increases, all there is larger change in garage's amount, carrying capacity, road speed etc., in addition the adverse effect of environmental activity road pavement constructional materials, make the Portland cement concrete pavement appearance damage in various degree of building for a long time, even namely there is the damage such as purt mud, faulting of slab ends, fracture after 3 ~ 5 years in use in the road surface in some area, if the cement concrete pavement in east, Beijing forthright, North 3rd Ring Road, interior street is within 7 years initial stages of use, the quantity of disconnected plate reaches 5 ~ 6.4%.Damaged condition concrete road faceplate panels 1 occurring disconnected plank split 2 is shown in Fig. 1.
Common traditional restoring and fastening method comprises: cutting planing surface in (1) Local Cracking place also builds the portland cement concrete material of identical type again; (2) the portland cement concrete material of identical type is directly built on whole plate planing surface re-pave or upper strata.But said method can not fundamentally solve, and Portland cement concrete pavement panel tensile strength is low, newly to build cement concrete distortion large thus cause the weak adhesive surface with original cement concrete to ftracture, again occur the problems such as cracking damage in a short time after cyclic reverse loading.
Therefore, urgently seeking a kind of new reparation and reinforcement means, to solve Portland cement concrete pavement intensity low, easy to crack, application life short, Long-Time Service high in cost of production fundamental issue.
In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.
