Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cement paste or cement mortar injection device.

As a general rule, when performing semi-rigid pavement using the materials listed above, cement paste or cement mortar should be poured evenly and evenly onto the paved surface of open-grain asphalt concrete (hereinafter referred to as "open-grain asphalt concrete"). There is a need to.

However, until now there was no equipment that met these requirements, so the method involved spreading the material using input, applying vibrations with a vibrating roller, and leveling it with a rubber rake, which required a lot of effort.

The present invention has been devised in view of the above-mentioned circumstances, and provides a cement paste or cement mortar injection device that is easy to handle and provides flat and homogeneous semi-rigid pavement.

Hereinafter, examples thereof will be described based on the drawings. FIG. 1 is a front view of the injection device according to the present invention, FIG. 2 is a side view thereof, FIG. 3 is a schematic sectional view taken along the line AA in FIG. 1, and FIG. 4 is a perspective view of the appearance of the roller frame.

As shown in FIG. 4, the shafts 17, 17 are inserted through the hollow rollers 2, 2 which are arranged in parallel to each other, respectively, and the ends of the shafts 17, 17 are rotatably constructed by supporting members 3, 3. to form a rectangular roller frame 4, and the shafts 17, 1 to cover the supporting members 3, 3.
At the same time, rubber belts 5 and 5 are stretched between the holes 7 and 7, respectively.
As shown in FIG. 1, the shaft 17,
The injection device 1 has a frame 7 and a hopper 8 attached to the hopper 17 via bearings 6, 6, 6, 6, and is configured to be movable while injecting the injection agent in the hopper 8 into the roller frame 4, The support member 3 includes spacers 1 rotatably fitted into the shafts 17, 17, respectively.
8 and ring 19.
2, 22 are interposed, a pulley 20 is fitted into the end of the shaft 17 and fixed to the shaft 17, and the connection arms 22, 22, 22, 2 protrude from the respective shafts 17, 17.
A horizontal member 21 is installed between the two and bolts 23 are tightened, and the rubber belt 5 is attached to each shaft 1.
It is stretched between the rings 19 fitted into the rings 7 and 17.

Note that 9 is an opening/closing handle for holding and injecting the injection agent in the hopper 8, 10 is a caster whose vertical position can be adjusted by an adjustment handle 11, and 12 is a hand handle.

Further, FIG. 3 13 shows an iron plate frame attached to the pedestal 7, and 14 is a rubber plate.

To explain the operation of the cement paste or cement mortar injection device 1 having the above configuration, the cement paste or cement mortar carried into the hopper 8 is transported by extending the caster 10 of the injection device 1 downward and using the hand handle 12. It is moved to the target open grain size ascon pavement 16 position (see Fig. 3).

Here, when the opening/closing handle 9 is opened after the caster 10 is retracted upward, cement paste or cement mortar 15 flows between the open-grained ascon pavement 16 surface in the roller frame 4 and the iron plate frame 13. Therefore, when the injection device 1 is pushed by the hand handle 12, the rubber belt 5 rotates due to the frictional force with the surface of the open grade ascon pavement 16.

The rubber belts 5, 5 serve to prevent the cement paste or cement mortar 15 in the roller frame 4 from protruding to the outside, and the rubber plate 14 in FIG. It has the function of uniformly injecting into the 16 surfaces of the open-grained Ascon pavement.

Therefore, in order to adjust the injection depth of cement paste or cement mortar, it is only necessary to adjust the height position of the cement paste or cement mortar in the hopper 8.

As described above, according to the injection device of the present invention,
With a simple mechanism, cement paste or cement mortar can be evenly and uniformly injected into the open-grain ascon pavement surface, and the depth of the injection layer can be changed arbitrarily by simply adjusting the height of the injecting agent in the hopper. This is a device that can be poured and leveled by one person, and can produce semi-rigid pavement that is much more economical than conventional construction methods.
