Background technology
Owing to very long highway can not complete by once-cast, so its construction is all by becoming Pork-pieces cement pavement plate segmentation to constitute with cement concrete at roadbed upper, being left with certain connecting sewing (also crying expansion joint) between such cement pavement plate.Connecting sewing under prior art is all perpendicular to road direction, and it also has an effect to leave flexible space to cement road panel block exactly, it is to avoid during temperature height, cement pavement plate crushes because splashing swollen generation stress or swells.Therefore, it can not remove.The driver having the longer driving age has such cognition, a lot of highways to fix to come into operation and shortly can start breakage occur, and the place of these breakages can be increasingly severe.As long as you carefully observe just it is seen that, these breakages the most all occur at connecting sewing, the place of i.e. two cement pavement plates handing-over.Why this place is susceptible to breakage, and it is many for tracing it to its cause.First, when automobile is pressed simultaneously against this one end of cement pavement plate through connecting sewing, two, left and right wheel, the center of gravity of two wheels is just on port, and it makes the pressure of this one end of cement pavement plate increase, and makes port bear the biggest impact.Simultaneously because all of connecting sewing is all perpendicular to road direction in prior art, thus causing the port of cement sheeting, to be used for bearing the area of this impact less, so bearing bigger pressure here, as shown in Figure 1.On the other hand, connecting sewing itself easily causes infiltration, when the termination of cement pavement plate occurs after breakage just infiltration to more rainwater to provide more path, the infiltration of rainwater has softened again the roadbed below connecting sewing, the support force making cement pavement plate port here obtain reduces, and also makes cement pavement plate port the most damaged further.Material is thus formed vicious cycle.Then damaged road surface be exactly the most always direction to the center of cement pavement plate stretch.These phenomenons became apparent from rainy season.Highway so damages step by step, and its generation largely causes the impact resistance decline of cement pavement plate two ends relevant with connecting sewing.Connecting sewing is inevitable, but the negative interaction of cement pavement can be alleviated and even eliminates by it.As long as facts have proved that the port of cement pavement plate is the most damaged, road is just not easy to damage.Therefore, improving the impact strength at connecting sewing is to extend the important channel in cement pavement service life.
Summary of the invention
In order to alleviate the connecting sewing negative interaction to cement pavement, improve the resistant to breakage ability of cement pavement port, extend the service life of cement pavement, the application takes following technical measures: port and the connecting sewing of the cement pavement plate on sandstone roadbed are set to be not orthogonal to road direction (as shown in Figure 2), or port and the connecting sewing of the cement pavement plate on sandstone roadbed are set to be not orthogonal to road direction, reinforcement plate (as shown in Figure 3) is set on the sandstone roadbed below connecting sewing, or port and the connecting sewing of the cement pavement plate on sandstone roadbed are set to be not orthogonal to road direction, the two ends of cement pavement plate thicken (as shown in Figure 4).
Advantage of this is that: the port of the cement pavement plate on sandstone roadbed and connecting sewing are set to be not orthogonal to the connected mode on road surface owing to this programme takes, the horizontal line that so can make cement pavement plate two ends is longer, it is used in the load area meeting automotive wheel to impact to increase, serves the biggest shock resistance effect.The most such structure can make the port of (successively) impact cement pavement plate during the left and right two-wheeled difference of automobile; this one end making this cement pavement plate is solely subjected to the impact of a wheel in the same time; the impact dynamics that the port same time of cement pavement plate born so can be made to be greatly reduced, be conducive to protecting cement pavement.Such structure extends the service life (as shown in Figure 2) of cement pavement plate and cement pavement on the premise of not spending more red cent；On the other hand this programme is on the basis of the above, it is also possible to add reinforcement plate in the lower section of connecting sewing.The impact so port of cement pavement plate can born passes to strengthen plate, the reinforcement plate bigger by area passes to sandstone roadbed, alleviate cement pavement plate port to the impact of sandstone roadbed, the deformation that reduces cement pavement plate port, extend its service life (as shown in Figure 3).This programme can also thicken (as shown in Figure 4) the two ends of cement pavement plate on the basis of the connecting sewing of the cement pavement plate on sandstone roadbed being set to be not orthogonal to road direction further.Such structure can make the intensity of the port of cement pavement plate be greatly increased, and enables it to the bigger impact dynamics born, considerably increases the resistant to breakage ability of cement pavement, extend its service life.

Detailed description of the invention
Road direction described herein refers to the extension of road or the direction travelled on road of vehicle.Port and the connecting sewing of described herein two cement pavement plates are set to be not orthogonal to road direction, say to be exactly that the horizontal line of cement pavement plate is not orthogonal to ordinate from another angle, are i.e. not equal to 90 degree, are also not orthogonal to road direction.
In order to alleviate the resistant to breakage ability that connecting sewing to the negative interaction of cement pavement, improves cement pavement, the service life extending cement pavement.This programme is set to port and the connecting sewing of two cement pavement plates to be not orthogonal to road direction, say, that the angle between two ends and the road direction of cement pavement plate is not 90 degree, as shown in Figure 2.The horizontal line that so can make cement pavement plate two ends is longer, makes cement pavement plate increase for the load area meeting automotive wheel to impact, significantly reduces the impact to roadbed.The most such structure can make the port of (successively) impact cement pavement plate during the left and right two-wheeled difference of automobile, this one end making this cement pavement plate is solely subjected to the impact of a wheel in the same time, the impact dynamics that the port of cement pavement plate so can be made to be born reduces, and serves the biggest cushioning effect.Such setting is the life-span extending cement pavement plate and cement pavement on the premise of not spending more red cent.
In order to alleviate the resistant to breakage ability that connecting sewing to the negative interaction of cement pavement, improves cement pavement, the service life extending cement pavement.This programme is set to be not orthogonal to road direction port and the connecting sewing of two cement pavement plates, and arranges reinforcement plate in the lower section of connecting sewing, as shown in Figure 3.After arranging reinforcement plate, the impulsive force that the port on connecting sewing both sides is born passes to have larger area and intensity higher reinforcement plate, then is passed to sandstone roadbed by strengthening plate, thus significantly reduces the cement pavement plate port surge to roadbed.The bigger impact dynamics that the port making cement pavement plate can bear, considerably increase cement pavement does breaking capacity.
In order to alleviate the resistant to breakage ability that connecting sewing to the negative interaction of cement pavement, improves cement pavement, the service life extending cement pavement.This programme is set to be not orthogonal to road direction the port of two cement pavement plates and connecting sewing, and increases the thickness at the two ends of cement pavement plate on this basis, as shown in Figure 4.After the two-end thickness of cement pavement plate increases, the intensity at the two ends of cement pavement plate is greatly increased, and it can make the bigger impact dynamics that the port of cement pavement plate can bear, and the most just considerably increases the resistant to breakage ability of cement pavement.
