Abstract:
A road sub-surface structure having pipe equipment is provided to drain water on the concrete paved layer and to prevent the road from being corroded by first and second connecting pipes and first, second, and third water passages. A road sub-surface structure having pipe equipment comprises a support net(200), and a pressing device(100). The support net has water flow pipes having a plurality of inlets. The pressing device has a body(110) and an elastic pressing rod(120). Second connecting pipes(153) are communicated with the water flow pipe. First connecting pipes(152) are communicated with perforated pipes(70). A sewer(151) is communicated with a drain pipe(80). The pressing rod has a cylinder engaged with a supporting piston. An elastic pressing member is installed at the lower surface of the pressing rod. Two sides of a first water passage are communicated with the sewer. A second water passage is communicated with the first connecting pipe. A third water passage is communicated with the second connecting pipe.

PURPOSE: A water resource preservation system using multi-layered block pavement and a construction method thereof are provided to preserve water resource and prevent sea surface from rising and control drought and prevent flood. CONSTITUTION: A water resource preservation system using multi-layered block pavement comprises a lower decontamination mat(51), a sand layer(52), a lower block(20), an upper decontamination mat(53), geogrid(54), and a surface block(10). The upper surface of the ground(50) is covered with the lower decontamination mat. The sand layer is paved on the upper surface of the lower decontamination mat as constant thickness. The lower block is coupled on the upper surface of the sand layer. The lower block is combined by engaging a groove and projection of an S-shaped connection part in the length direction. The upper surfaces of several lower blocks are covered with the upper decontamination mat. The geogrid is covered with the upper surface of the upper decontamination mat. The surface block is laminated on the upper surface of the geogrid.
Abstract:
A sidewalk block is provided to reduce the flood damage due to the heavy rain and to make the environment clean and beautiful. A sidewalk block(10) comprises a main body(20), one or more water storing part(30) which is formed in order to be flowed in from one side of the main body and store the water, an influx unit(40) formed in the upper side of the main body the water is flowed in into the freshwater part.
Abstract:
The present invention relates to a pavement of permeable volcanic rock blocks and, more specifically, a pavement of permeable volcanic rock blocks, in which permeable volcanic rock blocks are installed on the upper side of lower base bocks with an adhesive and a plurality of permeable line tunnels are formed at fixed intervals between the lower base blocks and the permeable volcanic rock blocks, so that rainwater is drained through the permeable line tunnels.
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:
PURPOSE: A deck member for preventing the bearing and slip is provided to prevent the slip of pedestrian and reduce the walk fatigue. CONSTITUTION: A deck member for preventing the bearing and slip comprises a base portion(10), a bearing portion(20) and a slip prevention portion. The base portion is formed into a fixed thickness. The bearing portion is into one body formed with the base portion and comprises a plurality of embossments(22). The bearing portion is formed in order that the line connecting the upper end of the embossment is a gradually curved. The slip prevention portion is formed between a pair of bearing portions and prevents the slip of pedestrian.
