Abstract:
PURPOSE: A superhigh speed permeable block road pavement system for flood, drought, global warming, desertification, sea level lift prevention, underground water restoration and a construction method thereof are provided to filter oil, tire dust, and heavy metals with a decontamination mat installed on a floor under a surface layer and a ground. CONSTITUTION: A superhigh speed permeable block road pavement system for flood, drought, global warming, desertification, sea level lift prevention, underground water restoration is composed of a fabricated structure block(20), a retention tank(52), a water tank(51), a pollution prevention bottom mat(53), a gravel layer(54), a pollution prevention upper mat(55), a sand layer(56), and a surface layer block(10). The retention tank stores water on the top of a ground(50) and passes away water. The water tank stores the water. The pollution prevention bottom mat covers the upper surface of the fabricated structure block. The gravel layer is piled up on the upper surface of the pollution prevention bottom mat. The pollution prevention upper mat covers the top of the gravel layer. The sand layer is spread on the top of the pollution prevention upper mat. The surface layer block is piled up on the sand layer. The plural surface layer blocks are connected each other by an upper longitudinal groove of both S-type connections and a projection.
Abstract:
A road drainage structure for preventing water storage is provided to absorb rainwater on the road rapidly and to preclude the road from being corroded by moving an elastic pressing rod upward and downward. A road drainage structure for preventing water storage comprises a support net(200), and a pressing device(100). The support net has an upper part with a curved shape and has a water flow pipe 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 pipes. 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 and elastically combined with by an elastic body. 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. The first and second water passages are moved together by a first opening and closing plate if internal pressure of the first water passage is increased to close communication holes of the first and second water passages. The first and third water passages are moved together by a second opening and closing plate if internal pressure of the first water passage is increased to close communication holes of the first and third water passages.
Abstract:
A synthetic resin sidewalk block for a park is provided to construct the sidewalk block promptly by excluding the foundation compacting process, to prevent slip by mounting a rubber footboard, and to restrict inundation of a sidewalk or block of a drain hole by actively draining rainwater. A synthetic resin sidewalk block includes a block(10) having a storage groove(11) curved inward, an insertion groove(12), plural through holes(13) permeating rainwater outside the storage groove and a support part(14), a rubber footboard(20) divided into an upper head part(21) and a lower screw part(22) and thread-connected to the insertion groove of the storage groove with the screw part, a support plate(30) installed in a lower part of the block to support the block and provided with a seating part(31) corresponding to the support part, an insertion groove(32) and a connection groove(33) recessed in a lower edge, and a coupler(40) connecting a couple of connecting bars(41) with fitting sills(42) by a connecting rod(43) and connecting the blocks by fitting the connecting bar to the connection groove of the support plate. Slip of a pedestrian is prevented by assembling the rubber footboard with the storage groove of the block.

본 발명은 도로용 보도블록에 관한 것으로서, 상세하게는 도로에 구성된 보도블록의 자체에서 빗물을 유입시켜 차도와 보도에서 발생되는 빗물이 한꺼번에 도로의 종배수관로로 유입되는 것을 차단하여 원활한 종배수관로의 흐름을 확보하도록 하고, 또한 배수블록의 상호간을 체결하도록 구성시켜 상부하중에 의한 침하현상을 방지하도록 하며, 보도블록의 내부로 유입되는 빗물은 집수운반용 보도블록으로 빗물이 집수되어 도로의 하부에 설치되는 횡배수관로에 연결시켜 원활한 배수처리가 가능하도록 형성된 도로용 보도블록에 관한 것이다. 본 발명은, 차도경계석과 보도경계석 사이에 설치되는 도로용 보도블록에 있어서, 상기 도로용 보도블록은, 차도경계석 측으로 집수운반용 보도블록이 설치되고, 측면으로 순착적으로 중간용 보도블록과 측면용 보도블록이 체결구에 의해 체결되어 보도 표면에서 발생되는 빗물을 보도블록의 상부에 형성된 배수홀을 통해 내부로 유입시켜 외부처리 하도록 구성하는 것을 특징으로 하는 도로용 보도블록을 제공한다.
