[0002] The existing pavement structure is to fill grouting material into a large-void asphalt mixed matrix, and utilize the mutual interlocking effect between the large-void skeleton structure and the cement-based material filled in the void to form the pavement strength. The semi-flexible pavement structure formed after the grouting material solidifies is stronger and can effectively resist vehicle rolling. During the grouting process of the grouting material, in order to prevent the grouting material from flowing around, it is necessary to seal the edges of the construction range.

[0003] The traditional edge sealing method relies on personnel to use brushes to block the grouting material, which is not ideal. The grouting material will overflow the grouting area and personnel need to monitor it at all times. Summary of the invention

DETAILED DESCRIPTION

[0025] In order to better understand the purpose, structure and function of the present invention, the present invention is described clearly and completely below in conjunction with the accompanying drawings.

[0026] like Figure 1 The edge sealing device for grouting pavement construction shown in the figure comprises a baffle 1, a fixing plate 2 and a clamping mechanism. The baffle 1 is located on one side of the fixing plate 2, and its upper part is connected to one end of the clamping mechanism, and a flexible sealing strip 3 is provided at the lower part. The flexible sealing strip 3 is used to seal the edge of the grouting range. The flexible sealing strip 3 has good sealing and elasticity, and can be made of rubber, silicone, polyester cloth and other materials; and the flexible sealing strip 3 can be detachably connected with the baffle 1, and it is easy to replace when it is damaged; in this embodiment, the flexible sealing strip 3 is bonded to the lower part of the baffle 1, and when it is damaged, the flexible sealing strip 3 can be torn off from the baffle 1.

[0027] The other end of the clamping mechanism is connected to the fixed plate 2; the clamping mechanism is used to drive the baffle 1 to slide up and down relative to the fixed plate 2. When in use, the device is placed on the edge of the grouting range, with the side wall of the baffle 1 in contact with the grouting position, and the lower part of the fixed plate 2 in contact with the road surface; the clamping mechanism is driven to work, driving the baffle 1 to slide downward along the fixed plate 2 until the flexible sealing strip 3 is in contact with the road surface. Since the flexible sealing strip 3 has a certain deformation ability, its seal is tighter and more fitted; at the same time, since the fixed plate 2 is also in contact with the road surface, the grouting position can be sealed for the second time to further prevent the grouting material from flowing out. Compared with the traditional method of relying on brush enclosure, the sealing is better, the possibility of grouting material overflow is greatly reduced, and there is no need for personnel to monitor all the time. It is not only practical, but also saves a lot of manpower.

[0028] The clamping mechanism exerts downward pressure and upward pulling force on the baffle 1, and its structural form includes but is not limited to linear reciprocating motion structures such as hydraulic cylinders, screws, and gear racks. In this embodiment, the clamping mechanism includes a guide assembly, a crank 4, a connecting rod 5, and a motor 6; the motor 6 is installed on the upper part of the fixed plate 2 through a motor 6 seat, and its output shaft is connected to one end of the crank 4, and the other end of the crank 4 is rotatably connected to one end of the connecting rod 5, and the other end of the connecting rod 5 is rotatably connected to the upper part of the baffle 1; the guide assembly limits the movement direction of the baffle 1. Its working principle is as follows: the motor 6 starts to drive the output shaft to rotate, thereby driving the crank 4 connected to the output shaft to rotate, and the other end of the crank 4 drives the connecting rod 5 to rotate, and under the limiting action of the guide assembly, the baffle 1 is driven to move upward or downward. The connection between the crank 4 and the connecting rod 5 is rotatably connected by a pin shaft. An ear plate 18 is provided on the upper part of the baffle 1, and a rotating shaft passing through the ear plate 18 is provided at the other end of the connecting rod 5.

[0029] Specifically, the guide assembly includes a vertically extending slide groove 7 provided on the fixed plate 2 and a slide bar 8 provided on the baffle 1, and the slide groove 7 is slidably matched with the slide bar 8. In this embodiment, three slide grooves 7 are provided, which are respectively located at the two ends and the middle position of the baffle 1, and three slide bars 8 are provided to cooperate with the slide grooves 7.

[0030] Taking into account that the baffle 1 is relatively long, a set of crank-connecting rods is used to drive the middle part thereof to move downward or upward. The force on both sides of the baffle 1 is relatively small, which may easily cause leakage of the grouting material. Furthermore, the clamping mechanism also includes a crank 2 9, a connecting rod 2 10 and a rocker 11. The rocker 11 is rotatably connected to the upper part of the fixed plate 2, and its end is connected to one end of the crank 2 9. The other end of the crank 2 9 is rotatably connected to one end of the connecting rod 2 10, and the other end of the connecting rod 2 10 is rotatably connected to the upper part of the baffle 1. Its working principle is the same as the above-mentioned crank-connecting rod principle, and the only difference is that this mechanism uses human power to rotate the rocker 11 as the driving force to prevent the clamping mechanism from being unable to be used when there is no electricity at the construction site or the motor 6 is powered off.

[0031] In order to make the two sets of crank-connecting rod structures synchronously drive the baffle 1 upward or downward, the motor 6 and the rocker 11 are symmetrically arranged on the upper part of the baffle 1, and the output shaft of the motor 6 is connected to the rocker 11 through a transmission belt 12. No matter whether it is driven by the motor 6 or the rocker 11, the power can be transmitted to the other set of crank-connecting rod structures through the transmission belt 12. Of course, in order to facilitate the installation of the motor 6 and the rocker 11, two brackets 13 are symmetrically arranged on the upper part of the fixing plate 2, one of which is rotatably connected to the rocker 11, and the other bracket 13 is provided with the motor 6.

[0032] like Figure 2 and Figure 3 The second structure of the edge sealing device for grouting pavement construction shown is the same structure as the first structure, and is given the same symbol and the same description is omitted. The only difference between the second structure and the first structure is that: the bottom of the fixing plate 2 is provided with a plurality of screw holes, and the inside of the screw holes is connected by threaded connection nails 15. When the road surface around the grouting is a dirt road, the fixing plate 2 of this structure can be used. The lower part of the fixing plate 2 fits the road surface, and the connection nails 15 are inserted into the soil at the bottom of the road surface. The installation of the fixing plate 2 is more stable, not easy to fall, and has better sealing. The connection nail 15 is provided with a plurality of auxiliary nails 16 inclined downward and away from it. In this embodiment, three auxiliary nails 16 are provided, and the three auxiliary nails 16 are evenly distributed circumferentially on the connection nail 15 to increase the contact area with the soil, so that the fixation with the soil is more stable.

[0033] like Figure 4 The third structure of the edge sealing device for grouting road construction shown in the figure is the same as the second structure, and is given the same symbol and the same description is omitted. The only difference between it and the second structure is that: the left and right ends of the fixed plate 2 are also provided with connecting grooves 17, and the groove width of the connecting groove 17 is equal to the thickness of the fixed plate 2 and the baffle 1. The edge sealing device of this structure is used when the edges of the grouting position are sealed on all four sides. Its use diagram is shown in Figure 5 As shown, two baffles 1 with edge sealing devices with connection grooves 17 are opposite to each other, and the edge sealing devices of the first structure or the second structure are inserted at the corresponding connection grooves 17; through holes can also be provided at the connection grooves 17, and threaded holes are provided on the fixing plate 2 inserted therein, and further fixed by bolts passing through the through holes and the threaded holes. Whether to install the auxiliary nails 16 during use is determined according to the actual situation on site.
