Abstract:
A moulded block (1) is proposed with water channels (11) below the top surface (2) for draining the latter. The aim is to make the periodic cleaning of these water channels necessitated by dirt deposition less frequent or unnecessary . This is done by providing at least one dirt retaining groove (5, 6) with at least one lateral overflow threshold (9, 10).
Abstract:
PURPOSE: An environmentally-friendly water-permeable sidewalk block for slope is provided to improve convenience of pedestrians or passage of baby carriages. CONSTITUTION: An environmentally-friendly water-permeable sidewalk block for slope comprises cement, stone power, a coloring agent, thinning-out tree sawdust, flame retardant, and aggregate. The sidewalk block employs an interference-fit different from the conventional rectangular frame, thereby obtaining more natural expression in case of upthrow of sidewalk blocks in the winter season or at curved surfaces of sidewalk blocks.
Abstract:
PURPOSE: A block with a drain function and a block system with the same are provided to drain a large amount of rainwater using a gap between the blocks. CONSTITUTION: A block(100) with a drain function comprises a block body(110), an inclined portion(120), and protruded portions(130). The inclined portion is formed on the top of the block body and is inclined from one side to the other side of the block body. The protruded portions are protruded from the side surfaces of the block body and form gaps between the block and adjacent blocks so that water can pass through the gaps.
Abstract:
A block equipped with a drainage and a ventilation function, its producing method, and a block multi-layer formed from materialization of the blocks are provided to employ a soil rock block in the lower portion of a road and a cement block on the surface of the road. A block is formed at the first side with the first concave-convex part(2). The second concave-convex part(3) is formed in the opposite side of a portion of the body corresponding to the first concave-convex part(2) such that the second concave-convex part is completely coupled with the first concave-convex part(2). The first concave-convex part(2) has an upper portion having the first protrusion in the shape of a semi circle and a lower portion having the first groove in the shape of a semi circle. The second concave-convex part(3) has an upper portion having the second groove and a lower portion having the second protrusion. A plurality of vent holes are provided on other surfaces of the body, on which the first and second convex-concave parts are not formed.
