Description
Technical field
This utility model belongs to highway engineering construction field, and specifically between a kind of prevention plates, the cement-concrete road joint of faulting of slab ends processes structure。
Background technology
Cement concrete pavement has the advantages such as intensity height, good stability, long service life, obtains in China and is extremely widely applied。But, cement concrete pavement must be provided with seam (expansion joint, construction joint etc.), seam areas very easily produces faulting of slab ends phenomenon due to the differential settlement of basic unit or roadbed between adjacent Cement Concrete Pavement Slab, the comfortableness of impact driving and safety, also can make due to the existence of faulting of slab ends wheel that Cement Concrete Pavement Slab produces percussion simultaneously, increase the destruction of cement concrete pavement。
Therefore, how carrying out the joint treatment of Cement Concrete Pavement Slab, the cement-concrete road joint arranging science processes structure, and then reduces and control settlement difference between Cement Concrete Pavement Slab, it is to avoid faulting of slab ends phenomenon needs further investigation。
At present, process and between reply Cement Concrete Pavement Slab, the main method of faulting of slab ends phenomenon is to arrange dowel bar reinforcement bar at seam crossing, one head is fixed in the Cement Concrete Pavement Slab of seam side, and other end is arranged in the Cement Concrete Pavement Slab of seam opposite side, and ensure itself and cement concrete adhesion, so that between prevention plates while settlement difference, concrete plate is kept freely to stretch within the specific limits。But, dowel bar reinforcement bar is general it is difficult to ensure that one is fixing and can freely stretch in other end so that Cement Concrete Pavement Slab is expanded with heat and contract with cold and is restricted, and affects the mechanical characteristic of Cement Concrete Pavement Slab；It addition, heavy duty dynamic wheel load repeatedly roll with impact under, the easy stress of dowel bar reinforcement bar is concentrated and was lost efficacy, and causes the destruction of joint of cement concrete pavement。During sedimentation uneven particularly in cement concrete pavement basic unit or soil matrix, very easily cause the faulting of slab ends phenomenon of seam crossing cement concrete pavement, and then make vehicle produce the percussion of road pavement through seam crossing, strengthen faulting of slab ends height further, have a strong impact on the comfortableness of driving and the service life of cement concrete pavement。
In sum, existing technology can't fundamentally solve the problem of faulting of slab ends between Cement Concrete Pavement Slab, needs the new thinking of searching and method badly。
Utility model content
For the deficiencies in the prior art, the technical problem that this utility model intends to solve is to provide the cement-concrete road joint of faulting of slab ends between a kind of prevention plates and processes structure, to solve the problem of faulting of slab ends between Cement Concrete Pavement Slab。
The technical scheme of this utility model described technical problem of solution is to provide the cement-concrete road joint of faulting of slab ends between a kind of prevention plates and processes structure, including supporting basic unit, Cement Concrete Pavement Slab, stiffener, sealing coat and enhancement Layer；It is characterized in that described Cement Concrete Pavement Slab offers stepped ramp type seam, Cement Concrete Pavement Slab is divided into the cement concrete pavement lower plate being mutually matched and cement concrete pavement upper plate with ledge structure；Between cement concrete pavement lower plate and cement concrete pavement upper plate, the stepped locations place of stepped ramp type seam is equipped with sealing coat；The length of described sealing coat is identical with the length of step, and sealing coat is positioned at 1/2 place of the thickness of Cement Concrete Pavement Slab；The upper seam of described stepped ramp type seam and the degree of depth of lower seam are the 1/2 of Cement Concrete Pavement Slab thickness；The centre of described cement concrete pavement lower plate and cement concrete pavement upper plate all adds the stiffener that length is length of bench 2 times, and one end of stiffener is positioned at the seam crossing of stepped ramp type seam；Enhancement Layer is laid between described cement concrete pavement lower plate and support basic unit。
Compared with prior art, this utility model has the beneficial effects that:
(1) original Cement Concrete Pavement Slab seam has been made 2 seams mutually staggered by this utility model, i.e. stepped ramp type seam, can avoid rainwater pass through seam directly under be seeped among support basic unit, it is prevented that support intensity after basic unit is subject to the erosion of water and reduce, it is to avoid produce purt mud phenomenon；
(2) add, in the middle of cement concrete pavement lower plate of the present utility model and cement concrete pavement upper plate, the stiffener that length is length of bench 2 times, thickness after stiffener is set is made to only have the concrete slab of the 1/2 of original Cement Concrete Pavement Slab thickness to have the load ability to bear identical with former Cement Concrete Pavement Slab, it is made to have enough strength support vehicular loads when there is basic unit's differential settlement, it is prevented that faulting of slab ends phenomenon between the plate caused because seam crossing dowel steel lost efficacy；
(3) one layer of enhancement Layer is laid between cement concrete pavement lower plate of the present utility model and support basic unit, enhancement Layer can be material that one layer of intensity is good more than foundation base intension and plate body (such as steel plate, plank) so that cement concrete pavement lower plate is not more than the cement concrete pavement upper plate sedimentation value at seam crossing in the sedimentation of seam crossing；And bottom cement concrete pavement upper plate the sedimentation value of seam crossing more than the sedimentation at seam crossing of the cement concrete pavement lower plate time, the cement concrete pavement lower plate of stepped ramp type seam crossing will support cement concrete pavement upper plate, reduce and control to produce between Cement Concrete Pavement Slab settlement difference, make seam both sides cannot form faulting of slab ends, it is ensured that the comfortableness of driving and safety。
