본 발명은 지하수 관정의 시공시 사용되는 투입낭으로서, 투수성소재의 외피와 필터재 또는 벤토나이트 등의 충전체로 구성된 원통형의 주머니이며, 굴착공에 투입되어, 관정의 관체와 굴착공 사이의 공간을 채우게 된다.The present invention relates to a pouring bag for use in the construction of a groundwater well, which is a cylindrical pouch made of a permeable material and a filler such as a filter material or bentonite. The pore is introduced into the excavation hole, Fill.

관정이란 관체(管體)로 구성된 우물로서, 하단부는 지하수가 함양된 대수층에 위치하며, 지하수 자체의 수압 또는 수중 펌프 등의 가압수단에 의하여 관수로 상태로 양수되는 우물을 말한다.A well is a well composed of a tube and the bottom is a well located in the aquifer where the groundwater is reared and pumped into the water by the water pressure of the groundwater itself or the pressure means such as underwater pump.

도 1은 일반적인 지하수 관정의 시공과정을 도시한 것으로, 이를 약술하면 다음과 같다.FIG. 1 shows a construction process of a general groundwater well, which is outlined as follows.

우선 착정 대상 지반에 굴착공을 형성한다.First, a drilling hole is formed on the ground to be ground.

굴착공의 형성시 공벽의 유지를 위하여 케이싱(31)을 굴착과 동시에 관입시키며, 굴착공의 하단이 대수층(21)의 소요심도에 도달하면, 관정을 구성하는 관체(32)를 투입한다.When the lower end of the excavation hole reaches the required depth of the aquifer 21, the tube 32 constituting the tunnel is inserted into the excavation hole.

이후, 유입부인 관체(32)의 하단부에는 모래 등의 투수성 필터재(41)를 트레 미(33)를 이용하여 포설하고, 포설과 동시에 케이싱(31)을 인발한다.Thereafter, a permeable filter material 41 such as sand is laid on the lower end portion of the tubular body 32, which is an inflow portion, by using the trams 33, and the casing 31 is pulled out simultaneously with the installation.

소정의 깊이로 필터재(41) 포설이 완료되면, 굴착공으로 인하여 교란된 토사층을 통하여 대수층(21)의 지하수가 누출되는 것을 방지하기 위한 차수층을 형성하는데, 일반적으로 굴착공과 관체(32) 사이에 액상 또는 분말상의 벤토나이트(42)를 주입함으로써 차수층을 형성하게 된다.When the filter material 41 is installed at a predetermined depth, an aeration layer is formed to prevent groundwater in the aquifer 21 from leaking through the soil layer disturbed by the excavation hole. Generally, The anhydrite layer is formed by injecting bentonite 42 in the form of liquid or powder.

굴착공과 관체(32) 사이에 주입된 벤토나이트(42)는 흡수 및 팽창하면서 차수층을 형성하게 되고, 도 1에 도시된 지반의 경우, 대수층(21) 상부에 불투수층(22)이 존재하는데, 벤토나이트(42)가 불투수층(22)에 형성된 굴착공을 밀봉함으로써, 상부 토사층으로의 지하수 누출을 방지하고, 상부 토사층으로부터의 오염물 유입을 차단하게 된다.Bentonite 42 injected between excavator and pipe body 32 absorbs and expands to form an aquifer. In the case of the ground shown in Fig. 1, there is an impervious layer 22 on the aquifer 21, 42 seal the excavation hole formed in the impervious layer 22 to prevent leakage of groundwater to the upper soil layer and to prevent contaminants from entering the upper soil layer.

차수층이 완성되면 나머지 굴착공을 되메우고 관체(32) 상부에 밸브 등의 부속설비를 설치함으로써 지하수 관정이 완성된다.When the aquifer is completed, the remaining excavation holes are filled and an accessory facility such as a valve is installed on the upper part of the pipe body 32 to complete the groundwater exchange.

이러한, 관정의 시공과정에 있어서, 관체(32)의 투입 후, 관체(32)와 굴착공 사이의 공간에 필터재(41) 또는 벤토나이트(42)를 주입할 시, 일종의 깔때기인 트레미(33)를 사용하게 되는데, 이들 분말상의 재료를 주입하는 것 자체가 매우 어려울 뿐 아니라, 굴착공 하부에 균일하게 포설된다는 보장이 없으므로, 시공의 정도(精度)를 확보할 수 없는 문제점이 있었으며, 시공시간 또한 장시간 소요되는 심각한 문제점이 있었다.When the filter material 41 or the bentonite 42 is injected into the space between the tubular body 32 and the excavation hole after the tubular body 32 is put in the construction process of the tubular body, However, there is a problem that it is difficult to inject the powdery materials themselves and it is not ensured that the material is uniformly placed under the excavation hole. Therefore, there is a problem that the accuracy of the construction can not be secured, There was also a serious problem that took a long time.

본 발명은 전술한 문제점을 감안하여 창안한 것으로, 지하수 관정을 시공함에 있어서, 관체와 굴착공 사이에 필터재 또는 벤토나이트 등의 충전체가 충전된 원통형의 투입낭을 투입함으로써, 신속하고 견고한 시공이 가능하도록 한 것이다.SUMMARY OF THE INVENTION The present invention was conceived in view of the problems described above, and it is an object of the present invention to provide a quick and robust construction of a groundwater well by injecting a cylindrical charging cistern filled with a filter material or a filler such as bentonite between the tube and excavator .

또한, 투입낭의 외피는 투수성소재로 구성하되, 망체에 수용성 피막체가 피복되어 지하수의 접촉시 피막체는 용해되고 조목(粗目)의 망체만이 남도록 함으로써, 투수성을 극대화할 수 있도록 한 것이다.In addition, the outer shell of the charging cask is made of a permeable material, and the water-soluble film body is covered with the netting so that the film body is dissolved when the groundwater is in contact, and only the coarse mesh is left, thereby maximizing the permeability .

본 발명의 상세한 구성을 첨부된 도면을 통하여 설명하면 다음과 같다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A detailed configuration of the present invention will be described with reference to the accompanying drawings.

우선 도 2는 본 발명의 일 실시예를 도시한 부분절단 사시도로서, 동 도면을 통하여 알 수 있는 바와 같이, 본 발명의 투입낭(10)은 원통형의 외피(12)와 그에 충전된 충전체(11)로 구성된다.FIG. 2 is a partially cutaway perspective view showing an embodiment of the present invention. As can be seen from the drawing, the charging cylinder 10 of the present invention includes a cylindrical shell 12 and a charging body 11).

외피(12)는 투수성소재로 구성되어, 외피(12) 내, 외부간을 지하수가 자유롭게 유동할 수 있도록 하며, 충전체(11)에는 투입 심도에 따라 모래 등의 필터재(41)나, 차수층 형성을 위한 분말상의 벤토나이트(42)가 적용된다.The cover 12 is made of a water permeable material so that groundwater can freely flow in the outer shell 12 and the filter material 41 such as sand or the like depending on the depth of penetration, Bentonite 42 in powder form for the formation of an aquifer is applied.

투입낭(10)의 외피(12)는 직물상 또는 망상의 소재가 적용될 수 있으며, 다소간의 신축성이 부여되어, 도 3에서와 같이, 굴착공내 투입시 자중에 의하여 자유롭게 변형되며 적층되어 공벽과 관체(32)의 외주면에 밀착되게 된다.As shown in FIG. 3, the outer shell 12 of the charging hopper 10 can be made of a woven or woven material, and is slightly deformed by its own weight when it is fed into the drilling hole, (32).

특히, 벤토나이트(42)는 흡수, 팽창하는 특성이 있으므로, 공벽과 관체(32)외주면에 더욱 견고하게 밀착된다.In particular, since the bentonite 42 has a characteristic of absorbing and expanding, it is more firmly adhered to the outer surface of the hollow wall and the tubular body 32.

이렇듯, 모래나 벤토나이트(42) 등을 투입낭(10)에 충전하여 투입함으로써, 신속한 투입이 가능함은 물론, 균일한 밀도로 굴착공을 채우게 되므로, 종래의 포설 방식에서는 기대할 수 없는 높은 정도(精度)의 시공이 가능하다.As described above, the sand and bentonite 42 are filled in the charging cistern 10 and charged, so that the charging can be performed quickly, and the excavation hole is filled with a uniform density. Therefore, ) Can be constructed.

한편, 도 4는 외피(12)로 인한 지하수의 유입저항을 최소화 하기 위하여, 수용성 피막체(14)를 적용한 것으로, 투입낭(10)의 외피(12)를 구성함에 있어서, 망체(13)에 수용성 피막체(14)를 피복함으로써, 건조상태에서는 외형을 그대로 유지하되, 일단 굴착공에 투입되어 지하수와 접촉하면 피막체(14)가 용해되면서 조목의 망체(13)만 남아, 내부의 충전체(11)가 그대로 노출되는 효과를 얻을 수 있도록 한 것이다.4 is a view showing a state in which the water-soluble film body 14 is applied in order to minimize the inflow resistance of the groundwater due to the shell 12. In constituting the shell 12 of the charging cylinder 10, By covering the water-soluble film body 14, the outer shape is maintained as it is in the dry state. Once the film is put into the excavation hole and brought into contact with the groundwater, the film body 14 is melted and only the wire- (11) is exposed as it is.

이러한 피막체(14)의 수용성은 그 소재로서 각종 수용성 수지 등을 적용함으로써 달성될 수 있다.The water-solubility of the coating film 14 can be achieved by applying various water-soluble resins or the like as a material thereof.

결국 본 발명의 기술요지는 내경과 외경이 각각 지하수 관정의 관체(32) 외경 및 굴착공 내경과 일치하는 원통형의 투수성 외피(12) 내부에, 입자상의 충전체(11)가 충전됨을 특징으로 하는 지하수 관정용 원통형 투입낭으로서, 상기 외피(12)는 망체(13)와 망체(13)에 피복된 수용성 피막체(14)로 구성됨을 특징으로 하는 지하수 관정용 원통형 투입낭이다.As a result, the technical feature of the present invention is characterized in that the particulate filler 11 is filled in a cylindrical permeable shell 12 having an inner diameter and an outer diameter that are respectively coincident with the outer diameter of the tube 32 of the groundwater tube and the inner diameter of the excavation hole Wherein the outer shell 12 is composed of a water-soluble film body 14 coated on the net 13 and the netting 13, and the outer shell 12 is made of a water-

본 발명을 통하여, 지하수 관정의 정밀한 시공이 가능할 뿐 아니라, 공기를 단축함으로써 관정 설치비용을 절감하는 효과를 얻을 수 있다.According to the present invention, it is possible not only to precisely construct the groundwater well, but also to reduce the installation cost by reducing the air.
