In practical use, the construction quality of graded broken stones is a key project for installing and using road panels, and the control of the pavement installation speed and the thickness of a sand cushion layer is directly influenced.
The graded broken stone layer is proportioned by adopting the technical scheme, so that the force transmission of the graded broken stone layer is facilitated. During construction, the water content of the mixture is strictly controlled to be 5% -6% so as to ensure a better compaction effect of the graded crushed stone layer.
Example six:
referring to fig. 2 to 5, the assembled waterproof and drainage road surface structure is different from the fifth embodiment in that: the lime soil layer 5 is of a U-shaped structure made of 6% lime soil with the layer thickness of 38-42 cm.
When in actual use, lime soil layer 5 adopts the U-shaped structure for the lateral wall that is located the blind ditch 1 of bed course 4 both sides links up with the inboard wall of the lime soil layer 5 of U-shaped structure mutually, has better effect to placing road surface rainwater and getting into lime soil layer 5.
The cushion layer 4 and the blind ditch 1 are wrapped in the blind ditch, so that the flow direction of the groundwater permeating into the pavement is effectively controlled, and the influence of the diffused drainage on the side slope is reduced.
Example seven:
referring to fig. 2 to 5, the assembled waterproof and drainage road surface structure is different from the sixth embodiment in that: the waterproof layer 3 adopts waterproof geotextile; the connecting piece 8 is a rectangular steel plate, and the upper surface of the rectangular steel plate is respectively and fixedly connected with two screw rods 9 in a vertical mode.
When in actual use, the waterproof geotextile technical scheme adopted by the waterproof layer 3 not only can satisfy the waterproof function, but also can conveniently extend the waterproof position. When the geotextile is laid, the lapping width of the longitudinal and transverse downslope is not less than 30cm, so that the water leakage at the lapping position of the waterproof geotextile is avoided.
When splicing between the precast concrete road boards before and after road surface construction, the front precast concrete road board and the rear precast concrete road board are connected through a connecting piece, screw rods on the rectangular steel plates are respectively arranged in connecting holes formed in the ends of the front precast concrete road board and the rear precast concrete road board, shockproof gaskets are respectively sleeved on the screw rods, the shockproof gaskets are lapped at the circular bead of the connecting holes, then nuts are screwed, and positioning rubber waves are installed on the screw rod ends of the screwed nuts to prevent rainwater on the road surface from permeating. The rectangular steel plate can be fixed by connecting a 16mm steel plate with M24 high-strength bolts.
The front and the rear precast concrete road boards are fixedly connected through the connecting pieces, so that the precast concrete road boards can be effectively prevented from moving when the vehicle longitudinally runs along a road, and the pavement structure is kept integral.
Example eight:
referring to fig. 4 and 5, a fabricated waterproof and drainage road surface structure is different from the seventh embodiment in that: the blind ditch 1 adopts a gravel blind ditch; the section of the rubble blind ditch is trapezoidal, the length of the upper bottom of the rubble blind ditch is larger than that of the lower bottom of the rubble blind ditch, and the upper surface of the rubble blind ditch is lower than that of the precast concrete road plate 2.
Furthermore, a blind ditch panel 7 is arranged on the blind ditch 1, so that the protection of the stone breaking side ditch is facilitated.
