Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a reinforced asphalt concrete pavement. Referring to fig. 1 and 2, the reinforced asphalt concrete road includes a mat layer 1, and the mat layer 1 is tamped by a gravel mat to ensure the stability of the road. And after the pad layer 1 is tamped, a base layer 2 made of asphalt concrete is poured on the pad layer 1. In order to reduce the road surface and lead to the road fracture because the vehicle rolls repeatedly or contract with cold, still bury soil check room 4 in the basic unit 2, soil check room 4 comprises the crisscross reinforcing bar that sets up of a plurality of, pours at basic unit 2 and lays soil check room 4 in basic unit 2 pours the template, and soil check room 4 can play the tensile effect of support to basic unit 2 after basic unit 2 solidifies the shaping. Then, a surface layer 3 made of concrete is poured on the surface of the base layer 2, and then, a rolling machine is used for rolling to ensure the smoothness of the road.

Referring to fig. 2 and 3, in the actual casting process, the soil cells 4 may fall on the bedding layer 1 due to the weight of the concrete, so that the soil cells 4 cannot be completely filled in the base layer 2. Therefore, in order to ensure the position of the soil cell 4 during pouring, a plurality of limiting parts 5 for limiting and fixing the soil cell 4 are embedded in the base layer 2. The limiting member 5 comprises a horizontal limiting rod 51, and a screw 52 is fixed at both ends of the limiting rod 51. Every screw rod 52 is kept away from support one end and is all provided with the toper guide part, and the toper guide part includes a plurality of splint 53, and a plurality of splint 53 set up along screw rod 52 circumference equidistant, insert screw rod 52 in bed course 1 under toper guide part guide effect to guarantee screw rod 52's stability, the grit in bed course 1 can be eaten into in the gap in the toper guide part simultaneously, thereby has guaranteed the stability that toper guide part and bed course 1 are connected. The screw rod 52 is provided with a through hole along the axis direction, a positioning rod is inserted into the through hole, the length of the positioning rod is longer than that of the screw rod 52, and after the screw rod 52 is inserted into the cushion layer 1, the positioning rod is extended out of the conical guide part and inserted into the cushion layer 1 in a mode of hammering by a hammer and the like. When the positioning rod extends out of the conical guide part, the clamping piece is spread, so that the stability of the conical wire guide part and the screw rod 52 is ensured.

Referring to fig. 2 and 3, in order to ensure the depth of the screw 52 inserted into the cushion 1, a positioning piece 54 is screwed on the screw 52, so that when the screw 52 is inserted into the cushion 1, the positioning piece 54 abuts against the surface of the cushion 1 to prevent the screw 52 from moving further downwards, thereby achieving the effect of controlling the insertion depth of the screw 52.

Referring to fig. 2 and 3, the screw 52 is further provided with a stopper plate 56, and the stopper plate 56 includes an abutting portion 561 and a blocking portion 562 perpendicular to the abutting portion 561. The abutting portion 561 has a through hole for the screw 52 to pass through, so that the limiting plate 56 is sleeved on the screw 52 and can move along the axial direction of the screw 52 and rotate around the screw 52. The screw rod 52 is further screwed with an adjusting nut, the abutting part 561 is overlapped on the adjusting nut, and the position of the limiting plate 56 on the screw rod 52 is adjusted by adjusting the position of the adjusting nut on the screw rod 52, so that the requirements of different geocells 4 on the height are met. The reinforcing steel bars are placed between the blocking part 562 and the screw rod 52 and are clamped and fixed, and meanwhile, two reinforcing steel bars can be fixed by each limiting part 5, so that the limiting effect on the soil cell 4 is further increased. When basic unit 2 was pour, locating part 5 supported spacingly to soil check room 4 to reduce soil check room 4 and move down the laminating on bed course 1, thereby guaranteed soil check room 4 to the reinforcing effect of basic unit 2.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
