Description

{THE JOINT FILLER SPREAD APPARATUS}

The present invention relates to a joint re-laying apparatus for a permeable block pavement for effectively filling a joint between blocks while minimizing pore clogging of a permeable block in a construction process of a floor material such as a water permeable block pavement, The present invention relates to a jointing re-laying apparatus for a water-permeable block pavement which allows a joint material to be filled directly into a space between blocks, thereby effectively constructing the joint material without loss of the joint material through a brush and vibration.

Generally, the sidewall block is manufactured by mixing the aggregate, sand and cement into a predetermined shape, and is repeatedly arranged and arranged so as to be meshed with each other in various shapes such as a walkway or a ship.

Since these blocks are sandwiched and arranged on the ground, they can not pass through the ground and the air. Accordingly, there is a problem that rainwater does not penetrate in a rainfall place even in a green space such as a walkway, a park, a plaza, and a highland site, thereby flooding the rainfall or causing an imbalance in the growth of the vegetation.

In addition, there are many problems due to the inconvenience to the pedestrian due to the excellentness on the sidewalk block, and the storm that has accumulated when the bicycle or the pedestrian is moved.

Accordingly, recently, a technique has been proposed in which a permeable block having fine pores is formed on the upper surface of a sidewalk block, thereby allowing rain or rain formed on the upper surface of the sidewalk to permeate.

The permeable block is constructed by closely adhering the blocks in the horizontal and vertical directions on the ground layer, and constructing a joint material between the block and the block.

The joints transfer the horizontal compressive force to the adjacent block and disperse it when the press block is constructed, and improve the interlocking effect of the block, and mainly sand, stone, or a combination thereof is used.

Conventional joint re-construction methods are all to spray grout or joint sand across the entire surface of the sidewalk block and then sweep it with a broom or use it for a few days to slowly penetrate the block by movement or rainfall.

In the past, the conventional joint re-construction method did not show any problem except that the dust was increased or the joint was lost due to the rainfall. However, recently, the application of the permeable block has been increased, There is a problem that the permeability is lowered from the beginning of the construction due to the blocking of the fine particles which are pores.

In other words, even if a permeable block having high performance is developed through technology development, the pore of the block surface is clogged in the process of filling the joint material, so that the function of the permeable block itself is lost and the purpose of constructing the permeable block is not achieved at all . Therefore, it is urgent to develop a technique for solving the pore clogging of the permeable block.

A moving means 400 such as a wheel is provided on the outer side surface of the installation means body 310 and the moving means 400 may be composed of a plurality of moving means 400 according to circumstances.

FIG. 5 shows another embodiment of the joint re-laying apparatus according to the present invention. As shown, a horizontal body 230 is provided in place of the inclined body in the gap adjusting means 200 of the joint re-laying apparatus.

The distance between the joint re-laying means 300 can be adjusted by sliding the movable bodies 220 to the horizontal body 230.

A dividing block 240 is provided at the center of the inside of the horizontal body 230 to divide and feed the joint material flowing into the horizontal body 230 into both ends of the horizontal body 230.

Since the joint re-laying apparatus of the present invention configured as described above adjusts the distance between the joint re-laying means 300 to supply the joint material only to the position where the joint material is to be fed and does not supply the joint material to the other water- , It is possible to provide the effect that the constructor can adjust the material, the amount of charge, and the compaction strength of the joint material under different conditions for each construction site so as to minimize the surface clogging due to the joint re-construction in the permeable press pavement.

In addition, since the joint re-laying apparatus of the present invention can adjust the gap according to the block size by using the gap adjusting means 200, it has a high expansion effect, and has a high filling speed by using the brush and vibration at the same time, It is possible to minimize the loss of ash, and it is expected that the permeability of the pitcher block packing is enhanced and the permeability sustainability is enhanced as compared with the prior art.
