영구 그라운드 앵커용 피복 인장재의 방수구조{Waterproof structure of covered tension member for permanent ground anchor}Waterproof structure of covered tension member for permanent ground anchor

본 고안은 자유장의 인장이 용이하도록 합성수지 튜브를 씌운 영구 그라운드 앵커용 인장재에 관한 것이며, 특히 튜브의 선단부에서의 방수성 강화 및 방수처리작업의 간편화를 도모한 영구 그라운드 앵커용 피복 인장재의 방수구조에 관한 것이다.The present invention relates to a tension member for permanent ground anchors covered with a synthetic resin tube to facilitate the tension of a free field, and more particularly to a waterproof structure of a coated tension member for permanent ground anchors for enhanced waterproofness and simplicity of waterproofing at the tip of the tube. will be.

마찰식 인장형 영구 그라운드 앵커에서 인장재(PC 스트랜드)는 정착장과 자유장 및 여유장으로 구분된다. 영구 그라운드 앵커의 앵커체를 지중의 천공에 삽입하고 그라우트를 주입하여 정착시킨 후 그 인장재에 정착하중을 걸 때 그라우트가 자유장 부분을 구속하지 못하게 PE 튜브를 씌우게 된다.In frictional tension type permanent ground anchors, the tension member (PC strand) is divided into anchorage, freefield, and clearance. When the anchor body of the permanent ground anchor is inserted into the perforation of the ground and the grout is injected and fixed, the PE tube is covered to prevent the grout from restraining the free field part when the anchoring load is applied to the tension member.

영구 그라운드 앵커는 인장재의 부식방지를 전제로 한다. 이에 따라 인장재의 자유장에 방청유(그리스)를 도포하고 PE 튜브를 씌워 보호한 다음에 정작장과의 경계부를 포함한 튜브의 선단부에 에폭시 수지를 도포하여 방수처리하고 테이프를 둘러 붙여 보호하게 된다.Permanent ground anchors are intended to prevent corrosion of the tension member. Accordingly, the rust preventive oil (grease) is applied to the free field of the tension member, and the PE tube is covered and protected, and then epoxy resin is applied to the front end of the tube including the boundary with the work station to waterproof and surround the tape.

이렇게 방수처리한 인장재는 설계정착하중에 상응하는 갯수대로 조합하고 튜브의 선단이 모인 부위를 실리콘 등의 실재로 한꺼번에 방수한 후 에폭시로 다시 감싼 다음에 테이프로 감아 흩어지지 않도록 결속하여 수지제 파형관에 삽입하고, 파형관의 선단에 에폭시 수지가 채워진 캡을 씌워서 인장형 영구 앵커를 이루게 된다. 캡 속의 에폭시 수지가 경화되면 인장재와 파형관 및 캡이 일체감을 이루게 된다.The water-tightened tensile material is assembled in the number corresponding to the design settling load, and the area where the tip ends of the tubes are assembled is waterproofed at once with a material such as silicone, wrapped with epoxy, and then wrapped with tape to be bound so as not to be scattered. Inserted, the end of the corrugated pipe is filled with an epoxy resin filled cap to form a tensile permanent anchor. When the epoxy resin in the cap is cured, the tension member, the corrugated pipe, and the cap form a sense of unity.

이러한 인장형 영구 그라운드 앵커용 인장재는 자유장 부분에 방청유를 아무리 잘 도포하여 튜브에 삽입할지라도 튜브 내부에 완전하게 방청유를 충전하기란 현실적으로 매우 곤란한 일이다. 때문에 튜브와 인장재 사이는 공간이 마련이라 방수성에 완벽을 기할 수가 없다. 강연선의 자유장 부분과 튜브 사이에 방청유가 완전 충전되지 아니하면 강연선의 자유장 부분이 경시적으로 부식되어 영구 앵커에 심각한 피해가 따르게 된다.The tension member for the tensile permanent ground anchor is practically very difficult to completely fill the rust preventive oil inside the tube, no matter how well the rust preventive oil is applied to the free field and inserted into the tube. As a result, there is a space between the tube and the tension member, which prevents perfect waterproofness. If the rust preventive oil is not completely filled between the free field of the strand and the tube, the free field of the strand will corrode over time, causing serious damage to the permanent anchor.

또, 튜브의 선단과 실재 및 정착장의 후단부에 테이프를 둘러감는 작업은 작업자의 숙련도에 따라 품질에 차이가 나기 일쑤여서 제품에 대한 신뢰도도 낮았다.In addition, the work of wrapping the tape at the front end of the tube and the rear end of the actual and the fixing station showed a difference in quality depending on the skill of the operator, so that the reliability of the product was low.

따라서, 본 고안의 목적은 튜브의 선단부에서의 방수성을 강화하고, 그 방수처리작업도 간편화하여 양산체제를 구축하는데 적합한 영구 그라운드 앵커용 피복 인장재의 방수구조를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a waterproof structure of a coated tension member for permanent ground anchors suitable for constructing a mass production system by strengthening the waterproofness at the tip of the tube and simplifying the waterproofing operation.

상기의 과제는, 방청유가 도포된 자유장에 튜브를 씌우고, 이 튜브의 선단부와 그 인접부위에 실리콘 등의 실재를 도포하여 봉한 상태에서 그 부위에 수축성 튜브제 슬리브를 씌우고 수축시켜 방수의 완벽성을 도모하고,그 방수작업도 간이화하여 생산성 향상에 보탬이 되도록 구성한 영구 그라운드 앵커용 피복 인장재로 달성하게 된다.The problem is that the tube is covered with a free field coated with rust-preventive oil, and a silicone tube or the like is applied to the front end of the tube and its adjacent portion to seal the tube with a shrinkable tube sleeve in a sealed state, whereby the tube is shrunk. In addition, the waterproofing operation is simplified, and thus, it is achieved by the coating tension member for permanent ground anchors configured to contribute to productivity improvement.

도 1은 튜브가 씌워진 인장재에서 자유장부와 정착부와의 경계에 실재를 도포하고 실재도포 부위에 수축성 슬리브를 씌운 상태의 부분 단면도1 is a partial cross-sectional view of a state in which the actual coating is applied to the boundary between the free tenant and the fixing unit in the tube-coated tension member and the shrinkable sleeve is applied to the actual application site.

1: 인장재 2: 방청유1: tension member 2: antirust oil

3: 튜브 5: 실재3: tube 5: real

6: (수축성 튜브제) 슬리브6: (shrinkable tube) sleeve

도 1에서, 인장재(1)에서 방청유(2)가 도포된 자유장(1a)에는 합성수지제 튜브(3)가 씌워져 있다. 방청유는 통상의 방법으로 도포된다. 즉, 인장재(1)의 자유장(1a)이 소선 벌림장치를 통과하면서 모든 소선이 일시에 벌어지고, 이렇게 벌어진 채로 소선들이 방청유통을 통과하면서 그 표면에 방청유가 묻어나가는 것이다.In Fig. 1, the free field 1a to which the rust-preventive oil 2 is applied in the tension member 1 is covered with a synthetic resin tube 3. Antirust oil is applied by a conventional method. That is, all the wires open at a time while the free field 1a of the tension member 1 passes through the wire open device, and the wires pass through the rust preventive oil while the anti-corrosive oil is buried on the surface.

실재(5)와 튜브(3)의 선단부(4) 및 자유장(1a)의 선단과 정착장(1c) 후단과의 경계부를 에워싸도록 슬리브(6)를 끼운다.The sleeve 6 is fitted so as to surround the boundary between the front end 4 of the actual material 5 and the tube 3 and the front end of the free field 1a and the rear end of the fixing station 1c.

슬리브(6)는 자연건조형 수축성 튜브제 또는 열수축성 튜브제이다. 열수축성 튜브에는 내주면에 열용해성 접착제(7)가 도포된 가열수축성 튜브제도 있다. 도 2는 지연건조형 수축성 튜브제 또는 열수축성 튜브제 슬리브(3)를 적용한 경우이고, 도 3은 열용해성 접착제가 도포된 열수축성 튜브제 슬리브(3)를 적용한 경우를 예시한 것이다.The sleeve 6 is made of a naturally dry shrinkable tube or a heat shrinkable tube. The heat shrinkable tube also includes a heat shrinkable tube having a heat-soluble adhesive 7 applied to its inner circumferential surface. FIG. 2 illustrates a case where a delay-drying shrinkable tube sleeve or a heat shrinkable tube sleeve 3 is applied, and FIG. 3 illustrates a case where a heat shrinkable tube sleeve 3 coated with a heat-soluble adhesive is applied.

도 2에서, 슬리브(6)를 가열하여 수축시킨다. 슬리브(6)의 수축에 따라 튜브(3)의 선단부(4)는 실재(5)에 의한 1차 방수에 이어 슬리브(6)에 의한 2차 방수마저 이루어지므로 튜브(3)의 선단부(4)에 대한 방수처리가 완벽해진다.In FIG. 2, the sleeve 6 is heated to shrink. With the shrinkage of the sleeve 6, the tip 4 of the tube 3 is made up of the first waterproof by the real material 5 and then the second waterproof by the sleeve 6. Waterproofing is perfect.

도 3의 경우에는 슬리브(6)를 가열하여 수축시킨다. 이때, 접착제(7)는 열 때문에 녹아서 튜브(3)의 선단부(4)와 실재(5) 및 정착장(1c)의 후단부에 달라붙는다. 슬리브(6)의 수축에 따라 튜브(3)의 선단부(4)는 실재(5)에 의한 1차 방수에 이어 슬리브(6)에 의한 2차 방수마저 이루어지므로 튜브(3)의 선단부(4)에 대한 방수처리가 더욱 완벽해진다.In the case of FIG. 3, the sleeve 6 is heated to shrink. At this time, the adhesive 7 melts due to heat and adheres to the front end 4 of the tube 3 and the rear end of the actual material 5 and the fixing cabinet 1c. With the shrinkage of the sleeve 6, the tip 4 of the tube 3 is made up of the first waterproof by the real material 5 and then the second waterproof by the sleeve 6. Waterproofing is more perfect.

도 4는 도 2의 인장재로 이루어진 인장형 영구 앵커(10)의 시공예를 나타낸 것이다. 도면부호 (11)은 파형관, (12)는 외부 그라우팅, (13)은 내부 그라우팅을 표시한다.4 shows a construction example of the tension-type permanent anchor 10 made of the tension member of FIG. Reference numeral 11 denotes a corrugated tube, 12 an external grouting, and 13 an internal grouting.

이상 설명한대로 본 고안의 인장형 영구 그라운드 앵커용 피복 인장재는 방청유가 도포된 자유장에 씌워진 튜브의 선단부와 그 인접부위에 실재를 도포하여 봉한 상태에서 그 부위에 수축성 튜브제 슬리브를 씌워 수축시킴으로서 테이프를 둘러감던 종래에 비해 튜브 선단부에서의 방수를 보다 완벽하게 처리할 수 있고, 또한 그 방수작업도 또한 매우 간이하여 영구 그라운드 앵커의 생산성 향상에도 보탬이 된다.As described above, the coated tension member for tensile permanent ground anchor according to the present invention is taped by contracting the shrinkable tube sleeve in the sealed state by applying the material to the front end and the adjacent part of the tube covered in the free field coated with rust-preventive oil. Compared to the prior art, the waterproofing at the tip of the tube can be more completely handled, and the waterproofing is also very simple, which contributes to the productivity improvement of the permanent ground anchor.
