Abstract
A construction method for oblique joint seam on concrete pavement is characterized by that the included angle between said joint seam and the longitudinal axis of pavement is 0-180 deg, but not 90 deg. Its advantages are less impact of wheel to joint seam and long service life and high load-bearing power of pavement.
Description
Technical field
The present invention relates to the job practices of a kind of rigid pavement seam.
Background technology
The rigid pavement is to be binding material with the cement paste that cement becomes with hydration, and rubble is an aggregate, and sand is inserts, through mix, paves, and vibrates and road surface that maintenance is built.The road surface characteristics: resistance to compression, bending resistance are drawn with abrasion resistance strong, and water stability, thermostability are good, and planeness, roughness are fit to traffic safety, and firm durable, maintenance cost is low, belongs to senior rigid pavement.Its shortcoming is to construct more numerous and diversely, butts manyly, butts director and is subjected to both sides that wheel impacts easily makes the seam groove phase and produces damagedly, and along with the increase of breakage, the road surface is damaged, and is difficult to repair after the road surface is damaged, and it is poor to repair the back overall performance.
Summary of the invention
In order to prolong the application life of rigid pavement, the present invention butts job practices to the rigid pavement and improves, and a kind of rigid pavement joint construction method that the rigid pavement is impacted in the use that reduces is provided.
The concrete technical scheme of this job practices is, changes transverse joint into oblique seam, R-joining and road surface vertically between angular range be greater than 0 degree, less than 180 degree, and be not equal to 90 and spend.
Described R-joining or for stretching seam, or be the seam that contracts.
Described R-joining or be the straight line seam, or be the broken line seam, or be that curve stitches.
Adopt the rigid pavement of process method construction of the present invention, have the advantage of two aspects: 1, because pavement joint vertically becomes an angle of slope with the road surface, so wheel can contact simultaneously with the both sides of seam groove, the instant impact of butt joint reduces relatively.2, because seam is oblique, two wheels can not be pressed on the seam simultaneously about vehicle, have alleviated jolting of vehicle, have just reduced the instant impact of butt joint yet.3, the impact force of the suffered wheel of oblique seam is compared with the suffered impact force of transverse joint, reduces the impact force more than 50%.Under static state, if vehicle weight is the A ton, the transverse joint pressure is 1/2nd A tons, and oblique seam pressure then is 1/4th A tons; Under dynamically, then impact force reduces more than 50%.4, because the seam impact force reduces, can suitably increase joint gap, make joint filling easy to operate, seam quantity is reduced, thereby prolong the application life on road surface.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
Fig. 2 is a broken line seam schematic diagram of the present invention.
The specific embodiment
When concrete pavement construction proceeds to surface construction during the stage, follow procedure: mounting template, lay sand cushion, seam be set, spice, pave, vibrate, floating, maintenance, joint filling construct, R-joining 1 is being set, when promptly stretching seam or contracting seam, to stretch seam or the seam that contracts is arranged to and angles are spent at vertical 2 one-tenths 60 degree angles, road surface or 120, see Fig. 1, can realize technique effect of the present invention.R-joining 1 also can be the broken line seam, sees Fig. 2.
Claims (3)
1, coagulate the oblique joint construction method in soil surface, it is characterized in that: change transverse joint into oblique seam, R-joining and road surface vertically between angular range be greater than 0 degree, spend less than 180, and be not equal to 90 and spend.
2, rigid pavement according to claim 1 joint construction method is characterized in that: described R-joining or for stretching seam, or be the seam that contracts.
3, rigid pavement according to claim 1 joint construction method is characterized in that: described R-joining or be the straight line seam, or be the broken line seam, or be that curve stitches.
