본 발명은 섬유제 망체(11)에 충전석(12)이 충전되어, 각종 하천, 교량, 해안 및 항만 공사에 호안공, 세굴방지공, 인공어초 또는 기초공 등으로 활용되는 섬유돌망태(10)에 관한 것으로, 섬유제 망체(11)를 개방하여 전개하고, 탄소계 미분체(微粉體) 및 수용성 수지 희석액의 혼합물을 망체(11)에 도포한 후, 망체(11)에 충전석(12)을 충전하고 망체(11)를 봉합하여 섬유돌망태(10)를 제작하고, 완성된 섬유돌망태(10)를 계획 위치로 이동하여 설치하는 것이다.
The present invention relates to a fiber gauze (10) filled with a filler stone (12) in a fibrous netting (11) and utilized as a water gutter, a scour prevention gullet, an artificial fish gullet or a foundation hole in various rivers, bridges, , The fibrous netting 11 is opened and expanded and a mixture of the carbon-based fine powder and the water-soluble resin diluting liquid is applied to the netting 11. The netting 11 is filled with the fillet 12, (11) is sewn to fabricate the fiber gauze (10), and the completed fiber gauze (10) is moved to the planned position and installed.

하천정비, 교량 건설, 홍수피해 복구, 내륙주운 운하 건설, 인공어초 조성, 방파제 구축, 방조제 건설 및 항만공사 등 각종 건설 공사에 있어서 사면보호, 호안, 방파 및 세굴(洗掘)방지의 목적으로 다양한 석재 충전식 망체(網體) 구조물이 시공되고 있으며, 망체(11)의 소재로도 강철 및 합성수지제 섬유 등 다양한 소재가 적용되고 있다.Various purposes for slope protection, revetment, breaking and scour prevention in river constructions, bridge construction, flood damage recovery, inland water canal construction, artificial reef construction, breakwater construction, A stone rechargeable network structure is being constructed, and various materials such as steel and synthetic resin fibers are applied as the material of the net 11.

이러한 석재 충전식 망체(11) 구조물 중 섬유제 망체(11)가 적용되는 섬유돌망태(10)는 철제 돌망태에 비하여 시공이 간편하고, 비교적 자유로운 변형이 가능하여 불규칙한 시공면에도 안정적으로 안착되는 특성이 있어, 최근 그 적용범위가 확대되고 있으며, 관련 종래기술로는 공개특허 제2003-49349호 등을 들 수 있다.The fiber gauze 10 to which the fibrous netting 11 is applied is simple in construction compared to an iron gauze and can be deformed relatively freely and stably stays on irregularly formed surfaces. Recently, its application range has been expanded, and related related art is disclosed in Japanese Patent Laid-Open No. 2003-49349.

도 1은 이러한 섬유돌망태(10)가 다양한 수공구조물에 적용된 상태를 도시한 것으로, 각각 교량의 교각 주변하상 세굴방지공 및 제체(堤體) 호안공에 적용된 상태를 도시하고 있다.FIG. 1 shows a state in which the fiber gauze 10 is applied to various hand structures, and each of the fiber gauze 10 is applied to a river bed scour prevention pit and a brim.

도 2는 섬유돌망태(10)의 외관을 도시한 사시도로서, 동 도면을 통하여 알 수 있는 바와 같이, 섬유돌망태(10)는 자루형태로 제작된 섬유제 망체(11)에 쇄석 등의 석재가 충전되어 제작되는데, 섬유제 망체(11)의 소재로는 일반적으로 폴리에스테르 섬유 등의 합성수지제 섬유가 적용된다.
2 is a perspective view showing the outer appearance of the fiber gauze 10. As can be seen from the figure, the fiber gauze 10 has a structure in which a stone such as a crushed stone is filled in a fibrous net 11 formed in a bag shape As the material of the fibrous netting 11, synthetic resin fibers such as polyester fibers are generally applied.

공개특허 제2003-49349호를 비롯한 섬유돌망태(10)는 철제 돌망태에 비하여 자유로운 변형이 가능할 뿐 아니라, 표면 안착성이 우수하여, 시공성 및 조적 구조 안정성이 우수한 장점이 있으나, 태양광 노출에 따른 합성수지제 망체(11)의 열화(劣化)로 인하여, 망체(11)가 파단되고 충전석(12)이 이탈되는 문제점이 있었다.The fiber gauze 10 including the open patent application No. 2003-49349 has a merit that it can be freely deformed as compared with the iron gauges, has excellent surface mountability, and is excellent in workability and structural stability. However, There has been a problem that the net 11 is broken and the charged stone 12 is detached due to deterioration of the net member 11. [

태양광에 의한 변성 내지 열화는 폴리에스테르 등 합성수지제 섬유 망체(11)에 있어서 불가피한 약점으로서, 특히 섬유돌망태(10)는 육중한 충전석(12)의 자중을 망체(11)가 전적으로 감당하게 되는 바, 섬유 조직의 미미한 강도 저하도 망체(11)의 파단을 초래하게 되며, 망체(11)의 파단은 충전석(12)의 응집상태를 이완하고 나아가 전체 섬유돌망체(11) 조적 구조를 와해하는 심각한 결과를 초래하게 된다.Modification or deterioration due to sunlight is an inevitable weak point in a synthetic fiber fibrous net 11 such as polyester. In particular, the fibrous gab 10 has a structure in which the net weight of the filled filler 12 is entirely covered by the net 11 The decrease in the strength of the bar and the fiber structure also causes the breakage of the net 11 and the breaking of the net 11 relaxes the aggregation state of the filler 12 and further breaks down the overall structure of the fiber- Resulting in serious consequences.

또한, 섬유돌망태(10)가 적용되는 사면보호공 또는 호안공 등은 전형적인 노천 구조물로서 직사 태양광에 상시 노출될 수 밖에 없으며, 따라서 섬유돌망태(10) 망체(11)의 열화 및 파손은 해당 구조물의 유지 관리상 심각한 애로점으로 작용할 수 밖에 없었다.
In addition, a slope protection hole or a sloping wall to which the fiber gauze 10 is applied is a typical open structure, which is always exposed to direct sunlight. Therefore, deterioration and damage of the fiber gauze 10, It was a serious problem for maintenance.

본 발명은 전술한 문제점을 감안하여 창안된 것으로, 합성수지제 망체(11)에 충전석(12)이 충전되어 설치되는 섬유돌망태(10)의 시공방법에 있어서, 망체(11)를 작업장에 전개하는 전개단계(S10)와, 탄소계 미분체, 물 및 수용성 수지를 혼합하여 피복액을 조성하고, 피복액을 망체(11)에 분무하여 도포하는 피복단계(S20)와, 망체(11)에 충전석(12)을 충전하는 충전단계(S31)와, 망체(11)를 봉합하고 계획 위치로 이동하여 설치하는 설치단계(S32)로 이루어짐을 특징으로 하는 피복 망체형 섬유돌망태의 시공방법이다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a method of constructing a fiber gabion 10 that is filled with a filler 12 in a synthetic resin net 11, A coating step S20 of spraying the coating solution onto the netting 11 by mixing the carbon-based fine powder, the water and the water-soluble resin to form a coating liquid; A charging step S31 of charging the stone 12 and an installation step S32 of sewing the netting 11 and moving it to a planned position.

또한, 상기 피복단계(S20)의 탄소계 미분체는 카본블랙 또는 분말 활성탄이고, 수용성 수지는 폴리비닐알코올임을 특징으로 하는 피복 망체형 섬유돌망태의 시공방법이다.
Also, the carbon-based fine powder in the covering step (S20) is carbon black or powder activated carbon, and the water-soluble resin is polyvinyl alcohol.

본 발명을 통하여, 섬유돌망태(10) 망체(11)의 유연성은 최대한 유지하면서도 변성 및 열화(劣化)를 효과적으로 억제할 수 있으며, 이로써 섬유돌망태(10)의 내구성을 획기적으로 향상시킬 수 있음은 물론, 섬유돌망태(10) 적용 시설물의 유지관리 편의성을 제고하고, 보수비용을 절감할 수 있다.

본 발명의 상세한 구성 및 수행과정을 첨부된 도면을 통하여 설명하면 다음과 같다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

우선 도 3은 본 발명의 망체(11)가 후술할 피복단계(S20) 및 충전단계(S31)의 수행을 위하여 전개된 상태를 도시한 것으로, 이렇듯 본 발명은 섬유돌망태(10)를 구성하는 망체(11)를 작업장에 전개하는 전개단계(S10)로 개시된다.3 shows a state in which the net 11 of the present invention is deployed for performing a covering step S20 and a filling step S31 which will be described later. (S10) of developing the work 11 to the workplace.

여기서 작업장은 섬유돌망태(10)의 시공 계획 지점 즉, 사면, 제방, 방파제, 항만 또는 교량 등 섬유돌망태(10) 설치 계획 지점 인근에 조성된 부지로서, 작업장에 전개된 망체(11)는 후술할 피복단계(S20), 충전단계(S31) 및 설치단계(S32)를 거쳐 섬유돌망태(10)로서 완성되어 시공된다.Here, the work site is a site constructed near the construction planning point of the fiber gauze 10, that is, a slope, a bank, a breakwater, a port or a bridge, and a net 11 deployed in the work site, The coating step S20, the filling step S31, and the installation step S32 are completed and completed as the fiber gauze 10.

작업장은 섬유돌망태(10)의 시공 계획 지점 인근의 평활한 지면에 조성될 수도 있으나, 도 3에서와 같이, 해당 지면을 굴착하여 요입부(20)를 형성하고 요입부(20) 표면에는 차단막(21)을 전개하여 작업장이 조성될 수 있으며, 이러한 요입부(20) 형성을 통하여 후술할 충전단계(S31)에 있어서 망체(11)에 대한 일층 용이한 충전석(12) 충전 및 봉합 작업이 가능하며, 불투수성 시트 등으로 구성되는 차단막(21)은 후술할 피복단계(S20)의 수행에 있어서 분무된 피복액이 주변 토양으로 침투되는 것을 차단하게 된다.The work site may be formed on a smooth surface near the construction planning point of the fiber gauze 10. However, as shown in FIG. 3, the ground surface is excavated to form a recessed portion 20, 21 can be expanded to form a work site. Through the formation of the recessed portion 20, filling and sealing operations can be performed on the net 11 in a filling step S31, which will be described later, And the barrier film 21 made of an impermeable sheet or the like is prevented from penetrating into the surrounding soil by the sprayed coating liquid in the coating step S20 to be described later.

전개단계(S10)가 완료되면, 도 4에서와 같이, 피복액을 전개된 망체(11)에 분무하여 도포하는 피복단계(S20)가 수행된다.When the developing step S10 is completed, a coating step S20 is performed in which the coating liquid is sprayed onto the expanded net 11 and applied as shown in Fig.

피복단계(S20)에 있어서 망체(11)에 도포되는 피복액은 탄소계 미분체(微粉體), 물 및 수용성 수지가 혼합된 것으로, 도 4에서와 같이, 교반조(21)에 저류된 피복액을 분무장치(32)로 압송하여 망체(11)에 분무, 도포하게 된다.The coating liquid applied to the net 11 in the covering step S20 is a mixture of a carbon-based fine powder, water and a water-soluble resin. As shown in Fig. 4, The liquid is sprayed onto the netting 11 by being fed by a spraying device 32.

피복액에 있어서 탄소계 미분체로는 카본블랙(carbon black) 또는 분말 활성탄이 적용될 수 있으며, 수용성 수지로는 폴리비닐알코올(polyvinyl alcohol)이 적용될 수 있다.In the coating solution, carbon black or powdered activated carbon may be used as the carbon-based fine powder, and polyvinyl alcohol may be applied as the water-soluble resin.

피복액은 수용성 수지의 희석액 즉, 수용성 수지 수용액을 우선 형성한 후, 탄소계 미분체를 혼합하여 조성하는 것이 바람직한데, 폴리비닐알코올이 충분히 용해된 상태의 희석액을 사전에 준비한 후, 현장에서 카본블랙 등의 탄소계 미분체와 함께 교반조(21)에 투입하여 교반하는 방식으로 피복액을 형성하게 된다.It is preferable that the coating solution is prepared by first preparing a diluted solution of a water-soluble resin, that is, a water-soluble resin aqueous solution, and then mixing the carbon-based fine powder to prepare a diluted solution in which polyvinyl alcohol has been sufficiently dissolved. Is added to a stirring tank (21) together with a carbon-based fine powder such as black and stirred to form a coating liquid.

즉, 폴리비닐알코올 등 수용성 수지의 균일하고 완전한 용해를 위하여, 수용성 수지와 물을 혼합한 후 가열하는 등의 전처리 공정을 거쳐서 희석액을 우선 조성한 후, 현장에서는 수용성 수지 희석액과 탄소계 미분체를 교반조(21)에서 균질 혼합함으로써, 간편하고 신속하게 피복액을 형성하는 것이다.That is, in order to uniformly and completely dissolve a water-soluble resin such as polyvinyl alcohol, a diluting liquid is first prepared through a pretreatment process such as mixing and mixing of a water-soluble resin and water, and then the water-soluble resin diluent and the carbon- And uniformly mixed in the tank 21, thereby forming a coating liquid easily and quickly.

수용성 수지 희석액은 폴리비닐알코올 등 수용성 수지 1중량% 내지 20중량%와 물 80중량% 내지 99중량%를 혼합하여 조성하는 것이 바람직하며, 적용되는 수용성 수지의 성상에 따라 농도를 증감함으로써, 완성될 피복액의 점도 및 속건성 등을 조절할 수 있다.The water-soluble resin diluting liquid is preferably prepared by mixing 1% by weight to 20% by weight of a water-soluble resin such as polyvinyl alcohol and 80% by weight to 99% by weight of water and the concentration is increased or decreased according to the properties of the water- Viscosity and quick-drying property of the coating liquid can be adjusted.

피복액을 구성하는 탄소계 미분체로는 전술한 바와 같이, 카본블랙 또는 분말 활성탄이 적용되며, 이들 탄소계 미분체는 100메쉬(mesh) 이하의 미세 분말상으로 가공되어 상기 수용성 수지 희석액과 혼합되는데, 완성된 피복액에 있어서 탄소계 미분체 함량이 미미할 경우 망체(11)의 충분한 피복 효과를 기대할 수 없고 탄소계 미분체 함량이 과다할 경우 피복액의 압송 및 분무에 장애가 발생될 수 있으므로, 탄소계 미분체 30중량% 내지 70중량%와 수용성 수지 희석액 30중량% 내지 70중량%를 혼합하여 피복액을 조성하는 것이 바람직하다.As described above, carbon black or powdered activated carbon is applied as the carbon-based fine powder constituting the coating liquid. These carbon-based fine powders are processed into a fine powder of 100 mesh or less and mixed with the water-soluble resin diluent. If the content of the carbon-based fine powder in the finished coating liquid is insufficient, a sufficient coating effect of the netting 11 can not be expected. If the carbon-based fine powder content is excessive, obstacles may occur in the feeding and spraying of the coating liquid, It is preferable to mix 30 wt% to 70 wt% of the fine powder and 30 wt% to 70 wt% of the water-soluble resin diluent to form a coating solution.

또한, 도 4에서와 같이, 피복단계(S20)의 수행 전반에 있어서, 조성된 피복액은 교반조(21)에 저류하여 상시 교반함으로써, 피복액내 탄소계 미분체의 편중을 방지하고 균일한 분산상태를 유지한다.In addition, as shown in Fig. 4, in the overall performance of the coating step S20, the formed coating liquid is stored in the stirring tank 21 and is always stirred, thereby preventing biased carbon fine powder in the coating liquid, State.

망체(11)에 대한 피복액의 도포는, 도 4에 도시된 바와 같이, 교반조(21)와 연결된 분무장치(32)로 피복액을 압송하여, 전개된 상태의 망체(11)에 분무하는 방식으로 진행될 수 있으며, 전술한 바와 같이, 작업장 즉, 요입부(20)에 차단막(21)을 설치하여 분무된 피복액의 토양 침투를 억제하고, 분무된 피복액의 섬유제 망체(11) 표면으로의 안착을 유도한다.As shown in Fig. 4, application of the coating liquid to the netting 11 is carried out by spraying the coating liquid by the spraying device 32 connected to the stirring tank 21 and spraying the coating liquid onto the elongated net 11 As described above, the shielding film 21 is installed in the work site, that is, the recessed portion 20, to suppress the infiltration of the sprayed coating liquid into the soil, and to the surface of the fibrous netting 11 of the sprayed coating liquid .

망체(11)에 대한 피복액 도포는 도 4에서와 같이, 차단막(21) 상층에 거치된 망체(11)로 탄소계 미분체가 균일하게 분산된 피복액을 분무함으로써 수행되는데, 이러한 분무 도포 외에 피복액이 저류된 수조에 망체(11)를 침지(沈漬)하는 등의 방식을 고려할 수도 있으나, 이 경우 피복액내 수지가 망체(11)의 섬유 조직에 과도하게 침투 및 함침(含浸)됨에 따라 완성된 망체가 경직되는 문제가 있다.The application of the coating liquid to the netting 11 is carried out by spraying a coating liquid in which the carbon-based fine particles are uniformly dispersed with the netting 11 mounted on the upper layer of the barrier film 21 as shown in Fig. 4. In addition to this spraying application, The resin in the coating liquid may be excessively infiltrated and impregnated into the fiber structure of the netting 11 to complete the process. There is a problem that the network becomes stiff.

즉, 망체(11)의 섬유 조직으로 과도하게 함침된 수지가 경화됨에 따라 망체(11)의 유연성이 상실되고 경직되어 후술할 충전단계(S31) 및 설치단계(S32)에서 작업성 및 조적성이 저하되는 것이다.That is, as the resin excessively impregnated into the fiber structure of the netting 11 is cured, the flexibility of the netting 11 is lost and stiff, and workability and operability are improved in the charging step S31 and the installing step S32 It will be degraded.

본 발명에 있어서 망체(11)에 대한 피복액의 도포는 망체(11) 자체의 강도 또는 내마멸성을 강화하는 것이 아니라, 망체(11) 표면에 탄소계 미분체를 부착하여 태양광을 차단하는 것인 바, 피복액내 수지 성분의 망체(11) 섬유 조직내 침투는 최소화하되 신속한 건조를 유도하여 탄소계 미분체가 안착될 수 있도록 분무 방식으로 피복액을 도포하는 것이 바람직하다.In the present invention, the application of the coating liquid to the netting 11 does not enhance the strength or abrasion resistance of the netting 11 itself, but rather adheres the carbon-based fine powder to the surface of the netting 11 to block sunlight It is preferable that the coating solution is applied by a spraying method so that penetration of the resin component in the bar and resin in the coating liquid (11) into the fiber structure is minimized, but rapid drying is induced and the carbonaceous powder is deposited.

또한, 이러한 피복단계(S20)에서는 피복액을 망체(11)에 분무, 도포한 후, 망체(11)의 건조를 촉진하기 위하여 열풍(熱風)을 가하는 공정이 추가될 수 있으며, 도 4에 도시되지는 않았으나 요입부(20) 상측에서 크레인 등의 장비에 연결된 온풍기를 가동하여, 피복액이 분무된 망체(11)에 열풍을 가하게 된다.In this covering step S20, a step of spraying the coating liquid onto the netting 11 and applying hot air to the net 11 to promote the drying of the netting 11 may be added. A hot air blower connected to equipment such as a crane is operated on the upper side of the recessed portion 20 to apply hot air to the netted body 11 sprayed with the coating liquid.

이렇듯 피복액이 도포된 망체(11)에는 수용성 수지 희석액이 건조됨에 따라 탄소계 미분체로 구성된 암막(暗幕)형 피막이 형성되며, 따라서 태양광 노출에 따른 망체(11) 섬유 조직의 열화(劣化)가 억제될 수 있다.As the water-soluble resin dilution liquid is dried in the netting 11 coated with the coating liquid, a dark-film-type coating composed of carbon-based fine particles is formed. Therefore, deterioration of the netting 11 of the netting 11 due to exposure to sunlight Can be suppressed.

피복단계(S20)가 완료되면, 망체(11)에 충전석(12)을 충전하는 충전단계(S31)가 수행된다.When the covering step S20 is completed, a charging step S31 for charging the filling stone 12 to the netting 11 is performed.

충전단계(S31)는 도 5에서와 같이, 요입부(20)에 망체(11)가 존치된 상태에서, 망체(11) 내부로 충전석(12)을 투입하는 방식으로 진행되며, 충전석(12)의 충전이 완료되면, 도 6에서와 같이, 망체(11)를 봉합하고 계획 위치로 이동하여 설치하는 설치단계(S32)가 수행됨으로써, 당해 섬유돌망태(10)의 시공이 완료된다.
5, the charging step S31 proceeds in such a manner that the charged stones 12 are charged into the inside of the net 11 in a state where the netting 11 is held in the recessed portion 20, 6, the installation of the fiber gauze 10 is completed by performing the installation step S32 of sealing the net 11 and moving it to the planned position, as shown in Fig.
