Description

Apparatus for spreading epoxy resin and aggregate used in thin surfaceing of concrete pavement}

The present invention relates to a device for spraying aggregate and epoxy resin for thin-layer paving of concrete roads. More specifically, it improves work efficiency and improves safety by automatically spraying aggregate and epoxy resin for thin-layer paving on concrete pavements. This relates to aggregate and epoxy resin spraying equipment for thin layer paving of concrete roads that can be secured.

In general, the top surface of concrete paved roads is worn due to the passage of numerous vehicles, especially overloaded vehicles, or cracks occur naturally over a certain period of time, so repairs are required to maintain the road. In this case, Thin-layer pavement method is being used as one of the road repair methods.

This thin-layer pavement method for roads is a repair method for concrete pavements damaged by wear, cracks, and damage due to vehicle traffic. In order to form a thin pavement layer of less than 1 cm, a layer of epoxy resin mixed with a hardener with a thickness of 5 to 1 cm is applied. It is used by spraying 6mm aggregate.

However, the conventional thin-layer packaging method has a problem in that the workability of thin-layer packaging is very low and work efficiency cannot be improved because workers directly spray the aggregate and epoxy resin used in thin-layer packaging on the packaging area.

In addition, thin-layer paving work on concrete pavements involves the risk of traffic accidents because workers perform paving work while vehicles are passing on the road next to them, and worker safety cannot be ensured, resulting in worker accidents.

Therefore, there is a need to develop technology that can automatically spray the necessary aggregates and epoxy resins when performing thin-layer paving work on concrete pavements.

Here, the operation of the aggregate and epoxy resin spreading device for thin layer pavement of concrete roads of the present invention having the above-described configuration will be described as follows.

First, the epoxy resin transfer pump 32 and the hardener transfer pump 42 mounted on the loading unit 12 of the work vehicle 10 are driven.

Accordingly, the epoxy resin filled in the epoxy resin tank 30 can be supplied from the discharge portion of the epoxy resin transfer pump 32 to the epoxy resin injector 100 through the epoxy resin supply pipe 34.

At the same time, the hardener filled in the hardener tank 40 can be supplied to the epoxy resin injector 100 from the discharge portion of the hardener transfer pump 42 through the hardener supply pipe 44.

Subsequently, the epoxy resin and curing agent supplied to the epoxy resin injector 100 are mixed in the mixer 120 as shown in FIG. 8, and the epoxy resin and curing agent mixed in the mixer 120 are injected into the epoxy resin injector 100. It is sprayed toward the road repair surface through the spray nozzle plate 110 of (100).

At this time, when the first motor 132 is driven to rotate in the forward and reverse directions at a certain cycle, the first roller 131 connected to the output shaft of the first motor 132 rotates and reciprocates along the first transverse rail 50. By moving, the first moving frame 130 on which the first roller 131 is mounted reciprocates along the first transverse rail 50, and the spray nozzle plate mounted on the lower part of the first moving frame 130 (110) also moves along the horizontal direction (left and right directions).

Therefore, the epoxy resin and hardener mixed in the mixer 120 can be evenly sprayed from the spray nozzle plate 110 toward the road repair surface having a predetermined width.

Next, the aggregate filled in the aggregate tank 20 is supplied to the aggregate spreader 200 through the aggregate transfer pipe 22 and falls into the auger screw 240.

At this time, as the third motor 242 is driven, the auger screw 240 rotates and moves and disperses the aggregate that has fallen to the auger screw 240 to the left and right.

Subsequently, the aggregate falling through the auger screw 240 passes through a plurality of aggregate distribution bars 220 mounted across the surface of the spraying frame 210, and the auger screw ( 240) The aggregate falling from the road does not clump up but is evenly dispersed and falls toward the road repair surface.

At the same time, the aggregate that falls from the auger screw 240 and passes through the aggregate dispersion bar 220 is prevented from being clogged or clumped due to the vibration drive of the vibrator 260 mounted on the rear surface of the spraying frame 210. It falls easily toward the road repair surface.

Ultimately, when the aggregate falls from the aggregate distribution bar 220 onto the road repair surface coated with epoxy resin, the aggregate distribution plate 250 mounted on the lower part of the spraying frame 210 evenly distributes the aggregate when the work vehicle moves. By spreading, the aggregate can be evenly spread on the road repair surface where the epoxy resin is applied.

In this way, while the work vehicle is moving, the epoxy resin mixed with a hardener is automatically sprayed onto the repaired road surface from the epoxy resin sprayer 100, and the aggregate spreader 200 evenly spreads the aggregate onto the repaired road surface before the epoxy resin is hardened. By enabling automatic spraying, the efficiency of thin layer paving work can be improved and work time can be shortened. Additionally, since workers do not have to manually spray aggregates and epoxy resin, etc., it is possible to ensure worker safety and prevent safety accidents. You can.
