Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the method of installing sidewalks and other items, and includes an interlocking part on the peripheral edge of the crushed stone layer formed on the base, and vertical holes. Lay large paving bricks arranged in rows so that adjacent bricks interlock with each other, and fill the joints of each brick and the vertical through hole with - to communicate with the layer. The purpose is to provide a TH11 installation method that is easy to install, has water permeability, and has good drainage.

In the present invention, as described above, a water-permeable crushed stone layer is laid on the base, a water-permeable layer is layered on top of that, and bricks with vertical holes are laid on top of that. , 1 liter of permeable sand was applied to the vertical holes and joints of each brick.
1), rainwater etc. on the paved surface will pass through the vertical holes of the bricks and the horizontal bridges at the joints and reach the next layer.
After passing through the sand layer, it reaches the crushed stone layer, and further permeates through the crushed stone layer to infiltrate into the soil.In this way, according to the present invention, the water permeability is good and the permeable pores are not blocked for a long period of time. Paving with good drainage is used.

In contrast, in the present invention, as described above, large bricks having interlocking portions on the peripheral edges are used and are laid so that the interlocking portions of adjacent bricks interlock with each other, thereby preventing relative movement of the bricks. # It is possible to construct joints, and since we used large-sized bricks in this project, the construction work is less labor-intensive than when using a large number of bricks as in the conventional brick construction method. is slightly simplified.

Furthermore, according to the present invention, the roadbed is constructed by applying a single pressure of # on the crushed stone layer, bricks are laid on top of the roadbed, and the installation is done using only the sand joints of T7fU bricks. Combined with the use of large bricks as described above, the construction earthen floor is simplified, construction costs are reduced, and the construction period is shortened.

Furthermore, according to the present invention, thick bricks are used, and there is no need to use sand for the joints or the lower layer of the bricks (because sand is used, the bricks can be easily removed and the ground Bricks can be reused for repair in the event of changes or relocation.

Furthermore, the bricks used as the paving material in the present invention are permeable in themselves, have a wear resistance about 6 times higher than that of concrete-based materials, do not change color, and have excellent durability.

The present invention also provides a peripheral edge 11Kli of the large body! Regarding a paving brick characterized by having an interlocking part with an I brick and having a row of vertical through holes, as described below, the brick is cut using the vertical through holes to form an end part. It makes it easier to manufacture things.

The present invention will be described below with reference to the illustrated embodiments.

Crushed stones with a diameter of 40W or less are placed on the subgrade (1), and there are gaps between the crushed stones [K
A crushed stone layer (2) loaded with sand and gravel is layered, and a small crushed stone layer (3) is layered on top of the crushed stone layer (2). Furthermore, this small crushed stone layer (3)
can be omitted.

Next, a KN layer (4) is deposited on top of the sand layer (4), and bricks (5) are laid on the same sand layer (4).

The brick (5) is formed into an H-shape with engaging recesses (5a) on both left and right sides, and is further provided with a large number of vertical holes (5k). Therefore, the front and rear surfaces of the bricks (51 (5)) adjacent to each other in the front and back direction collide with the tiles, and the meshing recesses (5a) of each brick (5)
), the edible projections (5C Brick (5)
Sand (6) is placed in the joints and vertical holes (5h) of each brick (5) to complete the paving.

When some of the longitudinal holes (5b) are arranged on the mutually perpendicular center lines of the brick (5) body, by cutting the brick along the X-X line and the Y-Y line KG in Fig. 1, It is possible to easily produce an end-use brick lj (for example, (S') at an irises of 2 mK) that is transferred to the end of a brick wIift body.

The present invention has been explained above with reference to Examples, but of course the present invention is not limited to five embodiments.
The present invention is not limited to such embodiments, and various design modifications may be made without departing from the spirit of the present invention.

Claims (1)

[Claims] (1) Most of the paving bricks, which have interlocking parts on the periphery and are lined with vertical holes, are laid on top of the multilayered crushed stone layer on the base, with a sand layer in between, so that adjacent bricks interlock with each other. -
A pavement construction method characterized by filling sand so as to communicate with the sand layer across the joints of each brick and the vertical hole. (a) A brick for paving, characterized in that the large body has an interlocking part with respect to an adjacent brick at the peripheral edge thereof, and vertical through holes are arranged in a row.
