Description

도로 및 토목공사용 판상모듈형 조립식 맹암거{PANEL TYPE MODULAR FILLED CONDUIT FOR ROAD AND CONSTRUCTION}PANEL TYPE MODULAR FILLED CONDUIT FOR ROAD AND CONSTRUCTION}

본 발명은 도로공사를 비롯한 각종 토목공사에 있어서 지하 배수를 목적으로 설치되는 맹암거(盲暗渠)에 관한 것으로, 발포합성수지 또는 발포콘크리트 등의 발포다공체(發泡多孔體)로 성형된 판상모듈(板狀module)(1) 내부에 개구부(開口部)를 형성하고 이 개구부가 가요성유공관(可撓性有孔管)(31)에 결합된 상태로 다수의 판상모듈(1)을 밀착 배열함으로써, 별도의 여재(濾材)(40) 포설 없이도 맹암거의 시공이 가능하도록 한 것이다.
The present invention relates to a blind rock which is installed for the purpose of underground drainage in various civil works, including road construction, plate-shaped modules molded of foamed porous bodies such as foamed synthetic resin or foamed concrete ( By forming an opening in the module (1) and arranging the plurality of plate-shaped modules (1) in close contact with the opening being coupled to the flexible oil pipe (31). , Without the installation of a separate filter (포) (40) is to enable the construction of the blind.

맹암거란 지중 수로인 암거의 한 형식으로서, 수로 내부에 자갈 또는 쇄석 등의 여재(濾材)(40)가 충전되어 수로의 외곽면을 통한 유입이 가능하도록 구성되며, 침투수 배수, 지하수 배수, 지하수위 저하 및 지하수 취수 등 다양한 목적으로 사용된다.A blind pit is a type of culvert, which is an underground channel, and is configured to allow inflow through the outer surface of the channel by filling a filter medium (40) such as gravel or crushed stone in the channel. It is used for various purposes such as groundwater level reduction and groundwater intake.

일반적으로 맹암거는 지반과의 접촉면에 설치되어 토립자의 유입을 방지하는 여과체, 맹암거의 단면을 유지하고 토립자의 유입을 방지하는 여재(40), 집수 및 배수로 역할을 수행하는 유공관(30)으로 구성되며, 여과체와 여재(40)로는 각각 부직포 및 자갈 등이 사용된다.
In general, the blind tiger is installed on the contact surface with the ground filter medium to prevent the inflow of soil particles, the filter medium to maintain the cross-section of the blind tiger and prevent the inflow of soil particles, drainage pipe 30 to serve as a collection and drainage Consists of, the filter medium and the filter medium 40 is used for each nonwoven fabric and gravel.

맹암거의 가장 일반적인 형태라 할 수 있는 자갈 포설식 맹암거는 도 1에서와 같이, 계획지점의 지반을 굴착하고, 굴착면에 부직포 등의 여과체를 덮은 후, 자갈 또는 쇄석 등의 여재(40)를 소정 깊이로 포설하고 유공관(30)을 거치하며, 다시 여재(40)를 포설하고 여과체를 폐합시킨 후 복토 및 도로 포장체 등의 상부구조물을 시공함으로써 완성된다.The gravel laying type mule tiger, which is the most common form of the scavenger, is excavated from the ground of the planned point as shown in FIG. 1, and the filter surface such as nonwoven fabric is covered on the excavation surface, and then the media such as gravel or crushed stone (40 ) Is installed to a predetermined depth and placed through the perforated pipe 30, and again by installing the filter medium 40, the filter body is closed and then the upper structure such as cover and road pavement is completed.

이렇듯 종래의 자갈 포설식 맹암거는 시공과정이 복잡할 뿐 아니라, 주변 지반보다 월등한 투수성을 가진 자갈 등의 여재(40)가 반드시 필요한 문제점이 있었다.As described above, the conventional gravel laying-type scavenger has a problem in that the construction process is complicated, as well as the media 40 such as gravel having superior permeability than the surrounding ground.

이에, 도 2에서와 같이, 합성수지 등으로 성형한 다공성(多孔性) 본체 내부에 인공 또는 천연소재 여과체가 적재된 기성(旣成)맹암거(41)가 개발되어 현장에서 터파기 후 다수의 기성맹암거(41)를 배치하고 유공관(30)을 배관함으로써 맹암거의 조립식 시공이 가능하게 되었으며, 이로써 시공 절차가 간소화되었을 뿐 아니라 자재 조달 편의성 또한 확보할 수 있게 되었다.Thus, as shown in Fig. 2, a ready-made blind limb 41, in which an artificial or natural filter material is loaded inside a porous body molded of synthetic resin or the like, has been developed, and then a large number of ready-made pores after demolition in the field. By arranging the blind lumber 41 and piping the perforated pipe 30, the prefabricated construction of the blind lumber was possible, thereby simplifying the construction procedure and securing convenience of material procurement.

이러한 조립식 기성맹암거(41)를 통하여 종래의 자갈 포설식 맹암거에 비하여 시공편의성이 일층 개선되었으나, 기성맹암거(41) 또한 여재(40)를 적재하는 일종의 용기 즉, 적재수단인 본체를 현장에서 일일이 조립한 후 유공관(30)을 결합하고, 본체 내부에 여재(40)를 적재하는 공정이 소요될 뿐 아니라, 종래의 자갈 포설식 맹암거는 터파기 트랜치(trench)의 불규칙한 형상에 따라 맹암거 자체가 변형되며 주변 지반과의 밀착성 및 일체성을 확보할 수 있는 반면, 형태가 고정된 기성맹암거(41)의 경우 주변 지반과의 밀착성 및 일체성을 충분히 확보할 수 없는 심각한 문제점이 있었다.
Although the construction convenience is further improved as compared with the conventional gravel laying type blind culvert through the prefabricated blind culvert 41, the ready blind culvert 41 is also a kind of container for loading the medium 40, that is, the main body as a loading means. After assembling one by one to combine the perforated pipe 30, and not only takes the process of loading the filter medium 40 inside the main body, the conventional gravel-delayed mud logger is a blind pit according to the irregular shape of the trench trench (trench) While the self-deformation can secure the adhesion and integrity with the surrounding ground, while the form of the fixed blind limb 41 is a serious problem that can not sufficiently secure the adhesion and integrity with the surrounding ground.

본 발명은 전술한 문제점을 감안하여 창안한 것으로, 조립식 맹암거를 구성하는 본체와 여재(40)를 분리하지 않고 발포합성수지 또는 발포콘크리트 등의 발포다공체(發泡多孔體)로 일체화함으로써 본체의 조립 내지 여재(40)의 적재 공정 없이도 신속한 시공이 가능하도록 하였으며, 가요성유공관(31)을 따라 밀착배열되는 다수의 판상모듈(1)로 맹암거를 구성함으로써 터파기 트랜치의 불규칙한 굴곡을 따라 맹암거의 종단 및 평면선형이 자유롭게 변화할 수 있도록 구성한 것으로, 이러한 과제는 발포다공체(發泡多孔體)로 형성된 상광하협(上廣下狹)의 제형(梯形) 판체인 상부판체(10)와 하부판체(20)가 접합되어 판상모듈(板狀module)(1)을 구성하고 다수의 판상모듈(1)이 밀착 배열되어 맹암거를 구성하되, 상부판체(10)의 하단 중심부에는 상측반원요부(11)가 형성되고 상측반원요부(11) 양측의 상부판체(10) 저면에는 돌출봉(12)이 각각 형성되며, 하부판체(20)의 상단 중심부에는 하측반원요부(21)가 형성되고 하측반원요부(21) 양측의 하부판체(20) 상면에는 결합공(22)이 각각 형성되어, 돌출봉(12)이 결합공(22)에 결합됨에 따라 상부판체(10)의 저면과 하부판체(20)의 상면이 접합되며, 상부판체(10)와 하부판체(20)가 접합됨에 따라 상측반원요부(11) 및 하측반원요부(21)에 의하여 형성된 원형 개구부(開口部)에는 외주면에 환상(環狀)의 돌부(突部)(32) 및 요부(凹部)(33)가 반복형성되고 다수의 통수공(39)이 천공된 가요성유공관(31)이 결합됨을 특징으로 하는 도로 및 토목공사용 판상모듈형 조립식 맹암거를 통하여 달성된다.

본 발명의 판상모듈(1)은 그 자체가 맹암거의 구조체이자 여과재로서 소기의 구조적 강성 및 투수성을 겸비하여야 하므로, 발포합성수지 또는 발포콘크리트 등의 발포다공체(發泡多孔體)로 성형된다.Since the plate-shaped module 1 of the present invention must have both structural structural rigidity and water permeability desired as a structure and filter medium of a blind rock, it is molded into a foamed porous body such as a foamed synthetic resin or foamed concrete.

본 발명의 판상모듈(1)은 발포합성수지의 경우 발포 사출성형을 통하여 제작될 수 있으며 발포콘크리트의 경우 프리캐스트 콘크리트(precast concrete)로 제작될 수 있는데, 이러한 발포다공체 판상모듈(1)의 투수성을 높이기 위한 수단으로서 사출성형 혼합재 또는 프리캐스트 콘크리트 골재의 일부로서 제올라이트(zeolite) 등의 다공성 소재를 혼합할 수도 있다.The plate module (1) of the present invention can be produced through foam injection molding in the case of foamed synthetic resin and can be made of precast concrete in the case of foam concrete, the water permeability of such a porous porous plate module (1) It is also possible to mix a porous material such as zeolite as part of the injection molding mixture or precast concrete aggregate as a means to increase the pressure.

도 4는 본 발명 판상모듈(1)의 분해사시도로서, 판상모듈(1) 내부에는 가요성유공관(31)이 결합될 수 있는 개구부가 형성되어야 하므로, 동 도면 및 도 6에서와 같이, 판상모듈(1)을 구성하는 상부판체(10)의 하단 중심부 및 하부판체(20)의 상단 중심부에 각각 상측반원요부(11) 및 하측반원요부(21)를 형성한다.4 is an exploded perspective view of the present invention, the plate module (1), because the plate-shaped module (1) inside the flexible oil pipe (31) to be coupled to the opening to be formed, as shown in Figure 6 and the plate module The upper semicircular portion 11 and the lower semicircular portion 21 are formed at the lower center of the upper plate body 10 and the upper center of the lower plate 20 constituting (1), respectively.

또한, 상부판체(10) 및 하부판체(20)간 긴밀한 접합을 위하여 상측반원요부(11) 양측의 상부판체(10) 저면과 하측반원요부(21) 양측의 하부판체(20) 상면에 각각 돌출봉(12) 및 결합공(22)을 형성하여, 이들 돌출봉(12) 및 결합공(22)이 상호 체결됨으로써 상부판체(10) 및 하부판체(20)가 접합되도록 한다.In addition, each of the upper plate 10 and the lower plate 20 protrudes on the lower surface of the upper plate body 10 on both sides of the upper semi-circular portion 11 and the upper surface of the lower plate body 20 on both sides of the lower semi-circular portion 21. The rod 12 and the coupling hole 22 are formed so that the protrusion bar 12 and the coupling hole 22 are coupled to each other so that the upper plate body 10 and the lower plate body 20 are joined to each other.

도 5는 본 발명의 조립도로서, 동 도면을 통하여 알 수 있는 바와 같이, 상부판체(10) 및 하부판체(20)로 구성되는 판상모듈(1)이 가요성유공관(31)과 결합됨과 동시에 가요성유공관(31)을 따라 밀착 배열됨으로써 맹암거를 형성하게 된다.5 is an assembly view of the present invention, as can be seen through the same figure, the plate-like module (1) consisting of the upper plate body 10 and the lower plate body 20 is coupled with the flexible oil pipe 31 By closely arranging along the flexible oil pipe 31, a blind culvert is formed.

본 발명에 적용되는 가요성유공관(31)은 그 사전적 의미에서와 같이 관체를 변형하여 곡선관로를 형성할 수 있도록 한 유공관(30)으로서 도 6에서와 같이, 상측반원요부(11) 및 하측반원요부(21)의 직경과 일치하는 외경을 가지며, 동 도면의 타원내 확대부에서와 같이 외주면에 환상(環狀)의 돌부(突部)(32) 및 요부(凹部)(33)가 반복형성되고 다수의 통수공(39)이 천공된다.The flexible perforated pipe 31 to be applied to the present invention is a perforated pipe 30 which allows the curved pipe to be formed by deforming the tubular body as in the prior meaning, as shown in FIG. 6, the upper semicircular recess 11 and the lower part. It has an outer diameter that matches the diameter of the semicircular recess 21, and the annular protrusions 32 and the recesses 33 are repeated on the outer circumferential surface as in the elliptic enlargement of the same figure. Are formed and a plurality of holes 39 are drilled.

본 발명의 가요성유공관(31)은 도 6의 타원내 확대부에 도시된 바와 같이 돌부(32) 및 요부(33)가 반복형성된 구조로서, 외력이 작용하면 요부(33)가 부분 변형되면서 관로가 만곡되게 되며, 따라서 극단적인 급절곡형 변형은 불가능하지만 인접한 판상모듈(1)간 미세한 이동에 따른 변형은 충분히 수용할 수 있게 된다.The flexible oil pipe 31 of the present invention is a structure in which the protrusions 32 and the recesses 33 are repeatedly formed as shown in the enlarged part of the ellipse of FIG. 6, and when the external force acts, the recess 33 is partially deformed. Is bent, so that the extreme sharp bending deformation is not possible, but the deformation due to the minute movement between the adjacent plate-shaped modules 1 can be sufficiently accommodated.

따라서 도 7에서와 같이, 터파기 트랜치의 불규칙한 형상에 대한 충분한 대처가 가능할 뿐 아니라, 종단 및 평면선형상 완만한 변화 또한 충분히 대처가 가능하여, 맹암거와 주변지반간 밀착성 및 일체성을 확보할 수 있음은 물론 자유로운 선형계획이 가능하다.
Therefore, as shown in Figure 7, not only can cope with the irregular shape of the trench trench, but also can cope with the change of longitudinal and planar linear smooth enough, to secure the adhesion and integrity between the blind and the surrounding ground Of course, free linear planning is possible.
