Description

방수시트 시공방법Waterproof sheet construction method

본 발명은 터널이나 박스 구조물 또는 지하 주차장 공사시 구조물의 내측으로 빗물 또는 오수가 유입되는 것을 방지하기 위한 방수시트의 시공방법에 관한 것이다.The present invention relates to a method of constructing a waterproof sheet for preventing rainwater or sewage from entering the structure of the tunnel or box structure or underground parking lot.

현재 시공중인 지하 구조물 공사의 경우 지하수 등이 구조물을 통해 내부로 스며들어 발생되는 안전상의 여러 가지 문제점이 종정 지적되어 왔었다.In the case of underground structure construction currently under construction, various problems of safety caused by groundwater seeping into the interior have been pointed out.

종래에는 이러한 이유로 발생되는 지하 구조물의 누수 등을 방지하기 위하여 구조물 외부에 빗물이나 지하수의 침투를 막아 주는 방수시트를 시공하여 왔다.Conventionally, in order to prevent leakage of underground structures generated for this reason, a waterproof sheet which prevents the penetration of rainwater or groundwater has been constructed.

제1도는 상술한 용도로 사용된 종래 방수시트의 시공상태를 나타낸 것이다.Figure 1 shows the construction state of a conventional waterproof sheet used for the above-described use.

방수시트(2)의 시공방법은 구조물(1) 전체를 한 번에 덮어 주는 폭을 갖는 방수시트의 제작은 현실상 어려우므로 소정 폭을 갖는 방수시트(2)를 기초 구조물(2) 외부에 소정 폭 포개지도록 덮어 시공한다.In the construction method of the waterproof sheet 2, it is difficult to manufacture a waterproof sheet having a width covering the entire structure 1 at a time, so that the waterproof sheet 2 having a predetermined width has a predetermined width outside the base structure 2. Cover it to overlap.

이때 방수시트(2)의 포개진 부위(2a)가 서로 용이하게 붙도록 하기 위해 토치로 가열하여 융착시켜 하나의 방수시트를 사용한 것과 같은 효과를 갖게 된다.At this time, the overlapped portion 2a of the waterproof sheet 2 is heated and fused with a torch in order to easily adhere to each other, thereby having the same effect as using one waterproof sheet.

이렇게 방수시트(2)를 시공하게 되면 지하수 등이 방수시트에 의해 차단되므로 지하 구조물(1) 내부로 물이 스며들지 않게 된다.When the waterproof sheet 2 is constructed, the groundwater is blocked by the waterproof sheet so that water does not penetrate into the underground structure 1.

그러나 이러한 방수시트(2)의 시공에도 불구하고 완공 후 종종 지하 구조물(1) 내부로 물이 스며들어 오는 문제가 부실시공으로 지적되어 다시 재시공하게 된다.However, despite the construction of such a waterproof sheet (2) after the completion of the water often seeps into the underground structure (1) problem is pointed out as a secondary construction will be rebuilt again.

이러한 부실시공의 첫째 원인은 제2도의 단면에서와 같이 작업자가 방수시트(2)가 연결되는, 즉 포개지는(overlap) 부위(2a)를 토치로 충분히 가열하지 않거나 일부 빼먹고 작업한 결과 서로 융착되지 않은 틈으로 물이 새어 들어가기 때문이다.The first cause of this sub-cavity is that the worker does not heat up or partially skip the overlapped portion 2a to which the waterproof sheet 2 is connected, as in the cross section of FIG. This is because water leaks into the gap.

둘째 원인은 방수시트(2)의시공 후 이러한 부분적인 불량시고 여부를 점검할 수 있는 방법이 없었다는 것이다.The second cause is that there was no way to check whether such partial failure after the construction of the waterproof sheet (2).

만일 완공 후에 이러한 문제점들이 발생하게 되면 보수에 따른 추가 경비부담과 공기의 지연 등으로 인한 적지 않은 손실을 가져오게 된다.If these problems occur after completion, they can cause considerable losses due to additional expenses and delays in maintenance.

본 발명은 상술한 문제점들을 해소하기 위한 것으로, 방수시트의 시공후 방수시트의 연결상태를 점검할 수 있도록 한 것을 기술적 과제로 한다.The present invention is to solve the above problems, it is to be a technical problem to be able to check the connection state of the waterproof sheet after construction of the waterproof sheet.

이하, 본 발명이 바람직한 실시예 및 작용을 첨부된 도면에 따라서 상세히 설명한다.Hereinafter, preferred embodiments and operations of the present invention will be described in detail with reference to the accompanying drawings.

제3도는 본 발명 방수시트의 시공방법을 나태낸 것이다.3 shows the construction method of the waterproof sheet of the present invention.

이 실시예에 의하면, 방수시트 시공방법은 방수를 위해 지하 구조물(100) 외부에 씌워지는 일정 폭을 갖는 방수시트(10)가 각각 일부 포개지도록 위치시킨 후 이들 사이에 길이 방향으로 유체통로가 형성되도록 간극(間隙)부재(20)를 삽입 고정하고 방수시트의 상호 접촉면을 가열하여 가압 융착시킨다.According to this embodiment, the waterproof sheet construction method is positioned so that each of the waterproof sheet 10 having a certain width to be covered on the outside of the underground structure 100 for the waterproofing to overlap each other, the fluid passage in the longitudinal direction therebetween is formed. The gap member 20 is inserted and fixed as much as possible, and the mutual contact surfaces of the waterproof sheet are heated and press-bonded.

이때 상기 간극부재(20)에 의한 유체통로는 방수시트(10)의 외측방향으로 형성되도록 한다.At this time, the fluid passage by the gap member 20 is formed in the outer direction of the waterproof sheet 10.

제4a도 ∼ 제4d도 는 각각 실시예에 따른 간극부재(20)의 구조와 시공상태를 나타낸 단면도이다.4A to 4D are sectional views showing the structure and construction state of the gap member 20 according to the embodiment, respectively.

제4a도의 간극부재(20)는 "I"형 단면의 띠 구조를 갖되 아래변이 위변보다 상대적으로 폭이 넓게 형성된 구조이고, 제4b도와 제4c도 는 각각 간극부재(20)의 단면이 "ㄱ"자 형상으로 띠 구조를 갖는 것과 "X"형 단면을 갖는 띠를삽입하는 것을 보여주고 있다.The gap member 20 of FIG. 4a has a band structure having an "I" -shaped cross section, and the lower side is formed to have a relatively wider width than the upper side. FIGS. 4b and 4c respectively have a cross section of the gap member 20 "a". It shows the insertion of a band having a "shaped" cross section and a "X" shaped cross section.

제4d도의 실시예에 의하면 간극부재(20)는 소정 직경을 갖는 파이프의 측면에 내통하는 통공이 일정간격으로 형성된 구조를 보여 준다.According to the embodiment of FIG. 4d, the gap member 20 shows a structure in which the through-holes passing through the side surface of the pipe having a predetermined diameter are formed at regular intervals.

본 발명은 이렇게 방수시트가 시공된 상태에서 시공상태를 유체통로를 통해 시험할 수 있다.The present invention can test the construction state in the state in which the waterproof sheet is constructed through a fluid passage.

제5도는 본 발명에 의해 시공된 방수시트의 수밀 시험과정을 나태낸 것으로, 먼저, 방수시트(10)의 융착면내 간극부재(20)에 이해 형성된 유체통로를 서로 연결시킨 후 각각의 유체를 채워 동일한 유압이 걸리도록 한다.Figure 5 shows the watertight test process of the waterproof sheet constructed by the present invention, first, connecting the fluid passages formed in the gap member 20 in the fusion surface of the waterproof sheet 10 to each other and fill each fluid Apply the same hydraulic pressure.

이때 이상이 있는 융착부위에서 유체가 방수시트의 외측으로 새어나오게 되므로 시트의 시공 불량 상태을 용이하게 점검할 수 있게 된다.At this time, since the fluid leaks out of the waterproof sheet at the abnormal fusion site, it is possible to easily check the poor state of construction of the sheet.

미 설명부호 51, 52 및 53은 각각 수밀시험을 위한 유압펌프, 유체를 담는 유체수용탱크 및 유체를 각 유체통로로 공급하는 유체공급라인을 나타낸 것이다.Reference numerals 51, 52 and 53 denote hydraulic pumps for watertight tests, fluid receiving tanks containing fluids, and fluid supply lines for supplying fluids to the respective fluid passages, respectively.

이 수밀시험에 사용되는 유체로는 유동성이 좋으면서 눈에 잘 띄는 색상이 착색된 것을 쓰며, 사용된 유체는 유체 통로로부터 회수하여 여러 번 반복 사용할 수 있도록 한다.The fluids used in this watertight test are those which have good flowability and are prominent in color, and the used fluids can be recovered from the fluid passages and used repeatedly.

이와 같이 간단한 방법으로 시트의 전체적인 시공상태 확인이 가능하므로 작업자도 대충대충 작업을 할 수 없게 되고, 만일 유체가 새어나오는 부위가 있을 경우 이 부위를 재 가열 융착하여 줌으로써 방수시트의 시공 완성도를 높일 수 있다.In this way, it is possible to check the overall construction state of the sheet by a simple method, so that the worker cannot roughly work, and if there is a leaking part of the fluid, it is possible to increase the construction completion rate of the waterproof sheet by reheating and fusion of this part. have.

또한, 이러한 시트의수밀시험으로 완공후 누수에 의해 발생할 수 있는 지하 구조물의 균열을 미연에 방지할 수 있게 된다.In addition, such a watertight test of the sheet can be prevented in advance to crack the underground structure that may be caused by leakage after completion.

제6도는 또 다른 방수시트 시공방법으로로서 직경이 작은 동선(60)을 간극부재(20)와 동일한 방법으로 시공한다.6 is another waterproof sheet construction method, the copper wire 60 having a small diameter is constructed in the same manner as the gap member 20.

그리고 시공을 마친 후에는 수밀시험으로 이 동선(60)이 양단에 저전압을 이용한 스파크 발생장치(70)를 연결하여 동선에 스파크를 발생시키게 되면 방쉬트(10)의 전합이 불량한 부위에서는 외부에서 스파크 발생상태로 알 수 있으므로 이부위만 방수시트를 재 융착시킬 수 있다.After completion of the construction, when the copper wire 60 is connected to the spark generator 70 using low voltage at both ends by the watertight test to generate spark on the copper wire, the sparks from the outside of the sheet 10 are poorly sparked from the outside. Since it can be seen as a state of occurrence, only this part can re-bond the waterproof sheet.

제7도는 본 발명의 또 다른 방수시트 시공방법에 따른 방수시트의 시공상태 단면도로, 전술한 본발명의 시공방법과 동일한 방법으로 방수시트(10)를 시공하고, 마지막으로 상기 간극부재(20)를 통한 유체통로로 유동성이 좋은 접착제(30)를 투입되도록 한다.7 is a cross-sectional view of a construction state of the waterproof sheet according to another waterproof sheet construction method of the present invention, the waterproof sheet 10 in the same manner as the construction method of the present invention described above, and finally the gap member 20 Into the fluid passage through the good fluidity of the adhesive 30 is to be introduced.

이 방법은 방수시트(10)의 상호 접촉면에서 서로 융착되지 않는 불량부위가 발생하더라도 접착재(30)가 이 틈새로 유입되어 이들을 접합시켜 주게 된다.In this method, even if defective parts are not fused to each other at the mutual contact surfaces of the waterproof sheet 10, the adhesive material 30 flows into this gap and joins them.

따라서 이 방법은 시트의 융착공정에서의 불량한 부위를 접착재가 이들이 서로 접착되도록한 보완적인 기능으로 물이 새어나지 않도록 해 줌으로써 별도로 시공상태를 점검할 필요가 없게 된다.Therefore, this method does not need to check the construction status separately by preventing water from leaking as a complementary function that allows the adhesive material to adhere to each other in the bad parts of the sheet fusion process.

상술한 작용으로 본 발명은 방수시트의 시공후 시공상태의 점검을 가능토록해 줌으로써 시공의 완성도 및 안정도를 높이고 공기의 단축과 아울러 비용을 절감할 수 있게 된다.By the above-described action, the present invention enables the inspection of the construction state after construction of the waterproof sheet, thereby increasing the completeness and stability of the construction, shortening the air and reducing the cost.

또한 불량공으로 인한 문제점을 미연에 방지할 수 있어 누수로 인한 부실 시공을 없애 줌으로써 보수에 따른 비용을 줄일 수 있다.In addition, it is possible to prevent problems due to poor work in advance, thereby eliminating poor construction due to leakage, thereby reducing the cost of repair.
