본 발명은, 보호재일체형합벽방수시트 및 이를 이용한 지하구조물 합벽복합방수시공공법에 관한 것으로 이를 좀 더 구체적으로 말하면, 지하구조물외벽 쪽에 방수하던 종래기술과는 달리 CIP 지하 지지연속벽 쪽에 「보호재일체형합벽방수시트」에 의해 방수되는 한편, 「지하구조물외벽」이 아직 축조되지 않은 넓은 공간을 이용하여 CIP 지하 지지연속벽에 「지지밀폐방수막」을 형성하되 이 「지지밀폐방수막」이 「지하구조물외벽」의 경계면이 되게 하면서 동시에 「지지밀폐방수막」을 통해 「지하구조물외벽」과 「CIP 지하 지지연속벽」이 합벽이 되도록 함으로써 「CIP 지하 지지연속벽」의 구조적 강도가 「지하구조물외벽」에 전가 추가·보강되어 「지하구조물외벽」의 방수 및 구조적 강도 및 그 내구성이 더한층 강화되게 한 발명에 관한 것이다.The present invention relates to a protective material-integrated wall waterproofing sheet and an underground structure combined-wall composite waterproofing construction method using the same, and more specifically, unlike the prior art that was waterproof on the outer wall of an underground structure, the CIP underground supporting continuous wall side While being waterproofed by a waterproof sheet”, a “supporting sealing waterproofing film” is formed on the CIP underground support continuous wall using a large space where the “exterior wall of the underground structure” has not been built yet. The structural strength of the ``CIP underground supporting continuous wall'' is increased by making the ``outer wall of the subterranean structure'' and the ``continuous wall under the CIP basement support'' a combined wall through the ``support sealing waterproofing membrane'' while making it the boundary of the outer wall. The present invention relates to an invention in which a transfer value is added and reinforced to further enhance the waterproof and structural strength and durability of the "outer wall of an underground structure".

「지지밀폐방수막」은, CIP 지하 지지연속벽에 접면·고정되게 「격자형태의 부착지지틀 설치 및 그 위에 보호재일체형합벽방수시트의 부착」된 지지구조를 말한다."Supporting sealing waterproofing membrane" refers to a supporting structure in which a grid-shaped attachment support frame is installed and a protective material integrated wall waterproof sheet is attached thereon so as to be in contact with and fixed to the CIP basement continuous wall.

또한 「지지밀폐방수막」과, 그리고 그 배면 공동에 방수액 혼합 몰탈을 충진·이에 의하여 견고한 「지지밀폐방수벽」이 형성됨으로써 이 「지지밀폐방수벽」이, 「지하구조물외벽의 현장 타설」시, 합벽거푸집(일 측; 외측거푸집)으로서 역할을 하게 된다.In addition, the ``supporting sealing and waterproofing membrane'' and the rear cavity are filled with a mixed mortar with a waterproofing liquid, thereby forming a sturdy ``supporting sealing and waterproofing wall'', which makes this ``supporting sealing and waterproofing wall'' during the ``placement of the outer wall of the underground structure''. , It plays a role as a combined wall formwork (one side; an outer formwork).

「CIP 지하 지지연속벽 설치」→「지지형태의 부착지지틀 형성」→「지지밀폐방수막 형성」→「배면 공동에 방수액 혼합 몰탈」→「지지밀폐방수벽 형성」→「지하구조물의 외벽의 현장타설」이 「bottom up」방식으로 순차적으로 이루어짐으로써 일련의 단계적 시공이 효율적·경제적으로 이루어지는 유용한 발명이다. 「Installation of CIP underground supporting continuous wall」→「Attachment support frame in support type」→「Formation of sealing and sealing film」→「Waterproof liquid mixed mortar in the rear cavity」→「Formation of sealing and sealing wall」→「External wall of underground structure It is a useful invention in which a series of step-by-step constructions is made efficiently and economically by sequentially performing “bottom up” method.

지하구조물의 합벽은 지하구조물의 외벽과 CIP 지하 지지연속벽이 합쳐진 것으로 지하구조물의 외벽과 CIP 지하 지지연속벽이 합쳐진 보강된 벽을 말한다.The combined wall of an underground structure is a combination of the outer wall of the underground structure and the CIP underground support continuous wall, and refers to the reinforced wall in which the outer wall of the underground structure and the CIP underground support continuous wall are combined.

CIP는 토공사중 흙막이 공법의 일종으로 CAST IN PLACE 약자로 지하 굴착작업을 위한 도심지의 현장타설 말뚝이다. JSP, LW, BTR, Slurry Wall 등이 이에 속한다. 보통 오거로 천공하고 콘크리트 몰탈 충진에 의해 이루어진다.CIP is an abbreviation of CAST IN PLACE as a type of earth-blocking method among earthworks, and it is an on-site pile for underground excavation work. These include JSP, LW, BTR, and Slurry Wall. This is usually done by drilling with auger and filling with concrete mortar.

도1에서와 같이 오거로 굴착한 후 이에 철근망을 삽입한 다음, 콘크리트를 주입한다. 주입되는 콘크리트 말뚝에 H-BEAM이 보강되기도 한다. 지하구조물의 설치를 위한 지하공간의 안전한 확보를 위해서다.As shown in Fig. 1, after excavating with an auger, a reinforcing bar mesh is inserted therein, and then concrete is injected. H-BEAM is sometimes reinforced on the concrete piles to be injected. This is to secure the safe underground space for the installation of underground structures.

지하구조물은 콘크리트구조물이다. 특히, 지하철, 지하차도, 아파트지하주차장 등이 그 대표적인 지하구조물이다.The underground structure is a concrete structure. In particular, subways, underground roads, and apartment underground parking lots are typical underground structures.

이러한 지하구조물의 문제점으로는, 첫째, 완성된 구조물의 누수발생의 문제점이고, 둘째, 지하수가 내부로 유출되어 토사의 압밀침하로 인한 지반침하로 이어져 도로침하로 인한 대형사고를 예방하고, 셋째, 가능하면 굴착 폭을 최소화하여 이에 따른 공사비를 저감하고 공사기간을 단축하며, 넷째, 인접건물과의 이격 거리를 최대한 확보하여 근접 굴착으로 인한 주변건물의 피해를 최소화하고, 다섯째, 보도 폭을 최소한 점령하여 시민들의 통행을 원활하게 유지하며, 여섯째, 작업 공간(B; 0.8m ~ 1.0m)의 좁은 공간에서 시트방수 작업을 진행하자면 작업 능율이 저하되고, 일곱째, 크레인으로 시트자재 반입 시 주변의 강재와 부딪쳐서 시트손상이 다발되고, 여덟째, 작업자가 지하로 진출입시 좁은 통로를 이용하여 한정된 계단을 이용하는 관계로 작업능율이 현저히 저하되고 아홉째, 합벽에 레미콘을 타설하고 다짐장비인 바이브레이터로 다짐할 시에 시트방수가 바이브레이터와 접촉하여 찢김이 발생하지 않토록 시트표면이 일정한 보호기능을 유지해야한다. 이에 반하여 보호재일체형합벽방수시트를 이용하여 합벽방수로 시공하면 방수작업을 위한 넓은 작업공간이 확보되면서 상기 첫째에서 아홉 번째 까지의 문제점이 모두 해결되는 장점을 들 수 있다.Problems of such an underground structure are, first, the problem of leakage of the completed structure, and second, the groundwater leaks to the inside and leads to ground subsidence due to the consolidation settlement of soil, preventing large-scale accidents due to road subsidence, and third, If possible, minimize the excavation width to reduce the construction cost and shorten the construction period.Fourth, minimize damage to neighboring buildings by securing the maximum distance from adjacent buildings, and fifth, occupy at least the width of the sidewalk. Therefore, it keeps citizens' passage smoothly. Sixth, if sheet waterproofing work is carried out in a narrow space of the work space (B; 0.8m ~ 1.0m), the workability decreases, and seventh, when the sheet material is brought in by a crane, the surrounding steel materials When hitting with and causing frequent damage to the sheet, eighth, when the worker enters and enters the basement, the work performance is significantly lowered due to the fact that the worker uses a limited staircase using a narrow passage, and ninth, when a ready-mixed concrete is placed on the wall and determined with a compaction device, a vibrator. The sheet surface must maintain a certain protective function so that the sheet waterproof does not come into contact with the vibrator and tearing does not occur. On the other hand, if a combined wall waterproofing sheet is used to secure a wide work space for waterproofing, all the problems from the first to the ninth are solved.

지하구조물의 누수는 콘크리트구조물이 갖는 불가피한 문제점이다.Leakage in underground structures is an inevitable problem with concrete structures.

계절적 온도 차이와, 전동차 및 대형트럭의 진동으로 인하여 헤어 크랙의 발생이 바로 누수의 주된 원인이다. 헤어 크랙은 반복된 온도 차이와 반복된 진동에 의해 성장된다. 지하구조물의 누수는 크랙의 성장결과이다.The main cause of leakage is the occurrence of hair cracks due to seasonal temperature differences and vibrations of electric vehicles and large trucks. Hair cracks are grown by repeated temperature differences and repeated vibrations. Leakage in underground structures is the result of crack growth.

성장된 크랙 폭이 0.3mm 이상 되면 에폭시로 주입 보수한다. 에폭시로 보수한다 해도 여름에 구조물이 팽창하면서 주입된 에폭시가 바스러지고 겨울이되면 구조물이 수축하면서 크렉이 다시 벌어지는 과정을 반복하면서 에폭시주입 효과는 단기간에 유명무실하게 되고 이과정에서 크렉에 주입된 에폭시가 콘크리트구조물에 강하게 부착되어 에폭시가 콘크리트를 물고 떨어지는 과정을 반복하면 크렉폭은 커질 수밖에 없으며 누수가 재발하고 그 자리를 다시 에폭시로 보수한다 하더라도 여름과 겨울을 겪으며 누수가 재발되어 에폭시보수는 일시적인 방수에 불과하다. 에폭시가 떨어진 틈새로 염화칼슘과 산성비 등이 침투되게 되면, 철근부식이 급격히 빠르게 진행되어 지하구조물의 내구성에 치명적인 문제가 발생한다.If the grown crack width is more than 0.3mm, it is injected and repaired with epoxy. Even if it is repaired with epoxy, the structure expands in summer and the injected epoxy crumbles, and in winter, the structure shrinks and the crack opens again, and the effect of epoxy injection becomes ineffective in a short period of time. If the epoxy is strongly attached to the concrete structure and repeats the process of dripping and dropping the concrete, the crack width will inevitably increase.Even if the leak recurs and the place is repaired with epoxy again, the leak will recur through summer and winter, and epoxy repair is temporary waterproofing. It's just that. When calcium chloride and acid rain penetrate into the gap where the epoxy fell, corrosion of the reinforcement proceeds rapidly and a fatal problem occurs in the durability of the underground structure.

종래 누수방지를 위한 시트방수처리는 축조된 지하구조물외벽에 방수 처리하는 방식이다. 즉, CIP 지하 지지연속벽을 시공한 후, 지하공간을 굴착하고, 지하공간에 지하구조물을 축조한 다음, 지하구조물의 외벽에 방수 처리하는 방식이기 때문에 CIP 지하 지지연속벽과 지하구조물의 외벽에는 방수를 위한 작업 공간(B)이 있어야만 한다. 작업 공간(B)은 적어도 1.0m ~ 1.5m가 필요하다. 그 작업 공간(B)내에서 작업자가 방수작업을 해야 하기 때문이다.The conventional sheet waterproofing treatment for preventing leakage is a method of waterproofing the exterior wall of a built underground structure. In other words, after constructing the CIP underground supporting continuous wall, excavating the underground space, constructing an underground structure in the underground space, and then waterproofing the outer wall of the underground structure. There must be a working area (B) for waterproofing. The working space (B) needs at least 1.0m to 1.5m. This is because the worker must perform waterproof work in the work space (B).

축조된 지하구조물의 외벽에다 방수하는 한, 이 작업 공간(B)은 불가피한 공간이다. 이때 도심지에 건설되는 지하철, 지하차도의 경우 그 굴착 깊이(H)는 통상 지하 10m에서 30m이다. 지하굴착 깊이(H)의 지지는 통상의 지지구조 및 그 방식에 따른다.As long as the outer wall of the constructed underground structure is waterproof, this work space (B) is inevitable. At this time, in the case of subways and underpasses built in urban areas, the excavation depth (H) is usually 10m to 30m underground. The support of the underground excavation depth (H) follows the usual support structure and its method.

작업 공간(B; 1.0m ~ 1.5m)은 지하구조물의 외벽을 보강하는 공간도 아니고, CIP 지하 지지연속벽을 보강하는 공간도 아니다. 단순히 시트방수를 위한 작업공간이고 방수작업이 끝나면 양질의 토사로 되메움되는 공간으로 안정된 토사를 굴착하여 되메움을 할 경우에 다짐을 아무리 충분히 한다해도 기존상태로 복원은 어려워서 느슨하게 되메움된 작업 공간(B; 1.0m ~ 1.5m)은 물길이 되어 누수를 가중시키고 내부의 느슨한 되메움으로 인하여 CIP측면의 밀림으로 넘어지면서 인접지반이 침하되어 인접건물에 피해가 발생하기 때문이다.The work space (B; 1.0m ~ 1.5m) is not a space to reinforce the outer wall of the underground structure, nor is it a space to reinforce the CIP underground supporting continuous wall. It is simply a work space for sheet waterproofing, and when the waterproof work is finished, it is a space that is refilled with high-quality soil. No matter how much you pledge it, it is difficult to restore it to its original state. This is because (B; 1.0m ~ 1.5m) is the length of the water, which increases the leakage and falls into the jungle on the side of the CIP due to the loose backfill inside, and the adjacent ground subsides, causing damage to the adjacent buildings.

지하구조물의 외벽 및 CIP 지하 지지연속벽에 구조적 보강도 전혀 하지 못하는 이러한 작업 공간(B; 1.0m ~ 1.5m)은 고가의 도심지에서의 축조에 있어 비경제적인 문제점이 있다.This work space (B; 1.0m ~ 1.5m), which does not have any structural reinforcement on the outer wall of the underground structure and the CIP basement continuous wall, has an uneconomical problem in construction in an expensive downtown area.

CIP 지하 지지연속벽은 도1에서와 같이 지하공간의 안전한 굴착 및 그 확보를 위해 H-BEAM이 보강되기 때문에 CIP 지하 지지연속벽을 지하구조물의 외벽의 구조재로서 역할을 할 수 있음에도 불구하고 작업 공간(B)이 그 사이에 위치·분리되게 함으로써 양 구조재가 서로 합력·보강되지 못하게 하는 문제점이 있다. 이때 작업 공간(B; 1.0m ~ 1.5m)은 오로지 지하구조물 외벽에 방수처리를 위한 공간으로서만 역할하기 때문이다.The CIP underground support continuous wall is a work space despite the fact that the CIP underground support continuous wall can serve as a structural material for the outer wall of the underground structure because H-BEAM is reinforced to secure the safe excavation and securing of the underground space as shown in FIG. There is a problem in that (B) is positioned and separated therebetween, so that both structural members cannot be combined or reinforced with each other. This is because the work space (B; 1.0m ~ 1.5m) serves only as a space for waterproof treatment on the outer wall of the underground structure.

지하굴착 시 집수된 지하수를 펌핑하면서 굴착이 진행되는데 굴착 깊이가 깊을수록, 방수시트작업공간이 넓을수록 펌핑 양이 많아지고, 또 주변 지하수까지 고갈시킴으로써 압밀침하를 촉진시켜 인접 건축물이 침하되는 피해가 발생되는 문제점이 있다.During underground excavation, excavation proceeds while pumping the collected groundwater.The deeper the excavation depth and the wider the waterproof sheet work space, the greater the amount of pumping, and by depleting the surrounding groundwater, consolidation settlement is promoted and the damage to the adjacent buildings is reduced. There is a problem that occurs.

되메움되는 깊고 좁은 작업 공간(B)은 양질의 토사로 되메움하면서 물다짐에 의해 콤팩트 시공이 되도록 규정하고 있다. 그런데 실제로는 되메움이 물다짐에 의해 콤팩트하게 다짐되지 않고 느슨하게 다짐되는 것이 현실이다. 느슨한 다짐은 결과적으로 물길이 되어 지하수가 불안정하게 유동되면서 지반지지력 또한 불안정하게 됨으로써 이로 인해 기존 주변구조물이 침하되는 문제점이 있게 된다.The deep and narrow work space (B) to be backfilled is regulated to be compact by water compaction while backfilling with high-quality soil. However, in reality, the backfill is not compacted by water compaction, but loosely compacted. As a result of loose compaction, groundwater flows unstable and groundwater becomes unstable, resulting in unstable ground bearing capacity, resulting in a problem that the existing surrounding structures settle.

지하 지지연속벽의 CIP의 모양은 도1과 같이 원형형태의 굴곡면을 이루고 있는 것이 특성이다. CIP 지하 지지연속벽이 수직평면과는 달리 굴곡면을 이루고 있으므로 방수처리가 용이한 지하구조물의 외벽 수직평면에 부착시키는 것도 이 때문이다.The characteristic of the CIP of the underground supporting continuous wall is that it has a circular curved surface as shown in Fig. 1. It is for this reason that the CIP underground supporting continuous wall has a curved surface unlike the vertical plane, so that it is attached to the vertical plane of the outer wall of an underground structure that is easy to waterproof.

CIP의 지하 지지연속벽의 굴곡면의 표면은 통상 숏크리트에 의해 보강된다. 설령 숏크리트에 의해 그 굴곡면이 수평면에 가까워질지라도 그 표면은 지하구조물의 외벽의 표면에 비해 거칠고 투박하여 그 표면조직이 치밀하지 못하다. 숏크리트는 뿜칠에 의한 타설이기 때문에 그렇다. 설령 이러한 숏크리트 표면에 방수시트를 부착한다 해도 그 부착면적이 충분치 않아 부착력이 못자라 쉽게 떨어지는 문제점이 있다. 나아가 숏크리트 표면조직을 치밀하게 하기 위해서는 많은 시간과 미장 등의 추가 작업이 요구됨으로써 비경제적이고 비효율적인 문제점이 있게 된다.The surface of the curved surface of the CIP underground supporting continuous wall is usually reinforced by shotcrete. Even if the curved surface is closer to the horizontal surface by shotcrete, the surface is rough and coarse compared to the surface of the outer wall of the underground structure, and the surface structure is not dense. This is because shotcrete is poured by spraying. Even if a waterproof sheet is attached to the surface of such shotcrete, the adhesion area is not sufficient, so that the adhesion is not grown, so it falls easily. Further, in order to make the surface structure of the shotcrete dense, a lot of time and additional work such as plastering are required, resulting in an inefficient and inefficient problem.

지하철, 지하차도, 아파트지하주차장 등의 지하구조물은, 전동차 및 대형트럭의 진동과, 계절에 따른 온도 차이(하절기의 온도상승과 동절기의 동결융해 온도하강)로 인한 헤어크랙의 발생이 구조적으로 불가피하다. 이때 산성비와 동절기에 살포되는 염화칼슘의 침투가 철저히 방지되어야한다. 염화칼슘과 산성비가 침투되면 헤어크랙의 성장과 더불어 철근부식으로 인해 지하구조물의 내구성에 치명적이 된다.Underground structures such as subways, underpasses, and apartment underground parking lots are structurally inevitable due to the vibration of electric cars and large trucks, and the occurrence of hair cracks due to the temperature difference according to the season (temperature increase in summer and freezing and thawing temperature decrease in winter). Do. At this time, the penetration of acid rain and calcium chloride sprayed in winter must be thoroughly prevented. When calcium chloride and acid rain penetrate, it is fatal to the durability of underground structures due to the growth of hair cracks and corrosion of the rebar.

지하구조물의 크랙 폭이 0.3mm 이상이 되면 통상 에폭시에 의해 주입 보수된다. If the crack width of the underground structure is more than 0.3mm, it is usually injected and repaired with epoxy.

에폭시에 의한 주입 보수는 일시적이 방수일 뿐이다. 주입된 에폭시는 쉽게 떨어질 뿐 아니라 또 떨어진 그 자리에 다시 주입된 에폭시도 쉽게 떨어져 반복적으로 누수가 재발되는 문제점이 있게 된다.The injection repair by epoxy is only temporary waterproof. Not only does the injected epoxy easily fall off, but also the epoxy injected again at the place where it fell off easily falls, and there is a problem in that water leakage repeatedly occurs.

⒜ 본 발명은 지하구조물외벽 쪽에 방수시트를 부착하던 종래기술과는 달리 CIP 지하 지지연속벽 쪽에 「보호재일체형합벽방수시트」에 의해 방수되는 한편, CIP 지하 지지연속벽에 접면되게 「격자형태의 부착지지틀 설치 및 그 위에 보호재일체형합벽방수시트의 부착」에 의해 「지지밀폐방수막」이 형성되게 하고, 이 「지지밀폐방수막」이 「지하구조물외벽」의 경계면이 되게 하면서 동시에 「지지밀폐방수막」을 통해 「지하구조물외벽」과 「CIP 지하 지지연속벽」이 합벽이 이루어지도록 함으로써 「CIP 지하 지지연속벽」의 구조적 강도가 「지하구조물외벽」에 전가 추가·보강되어 「지하구조물외벽」의 구조적 강도 및 방수성능향상과 그 내구성이 더한층 강화되게 함에 그 목적이 있고,⒜ In the present invention, unlike the prior art in which the waterproof sheet was attached to the outer wall of the underground structure, the CIP basement continuous wall is waterproofed by the ``protective material integrated wall waterproof sheet'', while the ``lattice type attachment'' in contact with the CIP basement continuous wall By installing the support frame and attaching the protective material-integrated wall waterproof sheet on it, a ``support sealing waterproof film'' is formed, and this ``support sealing waterproof film'' becomes the boundary surface of the ``underground structure outer wall'' and at the same time ``support sealing waterproofing Membrane" allows the ``underground structure outer wall'' and the ``CIP underground support continuous wall'' to form a combined wall, so that the structural strength of the ``CIP underground support continuous wall'' is transferred to and reinforced to the ``underground structure outer wall''. Its purpose is to improve the structural strength and waterproof performance and to further strengthen its durability,

또한, Also,

압착PE장섬유 부직포(30)의 두께(t)와, 그리고 상·하부 층(u)(d)에 침투·앵커된 수용성 고무화아스팔트(14) 및 고 점착성 고무화아스팔트(24)가 각기 압착PE장섬유부직포(30)로부터 상하 연장·돌출(18)(28)된 두께의 총합이 3.0~3.5mm가 됨을 특징으로 하는 보호재일체형합벽방수시트이다.The thickness (t) of the compressed PE filament nonwoven fabric (30), and the water-soluble rubberized asphalt (14) and high-adhesion rubberized asphalt (24) penetrated and anchored in the upper and lower layers (u) (d) are respectively compressed. It is a protective material integrated wall waterproof sheet characterized in that the total thickness of the vertically extended and protruded (18) (28) from the PE filament nonwoven fabric (30) is 3.0~3.5mm.

먼저, 압착PE장섬유 부직포(30)의 특성과 그 기능에 대하여 살펴본다.First, it looks at the characteristics and functions of the compressed PE long fiber nonwoven fabric 30.

첫째, 압착PE장섬유 부직포(30)자체가 갖는 인장강도가 크다.First, the tensile strength of the compressed PE long fiber nonwoven fabric 30 itself is large.

그뿐 아니라 수용성 고무화아스팔트(14)와, 고 점착성 고무화아스팔트(24)가 침투·앵커된 상태에서 저항 인장강도가 증진되는 특징이 있다.In addition, the water-soluble rubberized asphalt 14 and the high-adhesive rubberized asphalt 24 are characterized in that resistance and tensile strength are improved in a state in which they are penetrated and anchored.

둘째, 수용성 고무화아스팔트(14)와, 고 점착성 고무화아스팔트(24)의 침투·앵커 결착이 용이하다.Second, it is easy to penetrate and anchor the water-soluble rubberized asphalt 14 and the high-adhesive rubberized asphalt 24.

셋째, 침투·앵커된 수용성 고무화아스팔트(14)에 의해 압착PE장섬유가 불투수성이 되면서 방수기능을 하게 된다.Third, the crimped PE filament becomes impermeable by the water-soluble rubberized asphalt 14 penetrated and anchored to provide a waterproof function.

넷째, 고 점착성 고무화아스팔트(24)에 의해 격자부착면(410)과의 강력한 부착기능을 한다.Fourth, it has a strong attachment function to the grid attachment surface 410 by the high-adhesion rubberized asphalt (24).

다섯째, 격자부착면(410)과의 강력한 부착력은, 이에 대응된 고 점착성 고무화아스팔트(24)의 앵커·결착력에 의해 지지·강화된다.Fifth, the strong adhesion to the grid attachment surface 410 is supported and reinforced by the anchoring and binding force of the high-adhesive rubberized asphalt 24 corresponding thereto.

다음으로, 「지지밀폐방수막(500)」의 형성 및 그 인장강도와, 그리고 「지지밀폐방수벽(520)」의 형성 및 그 기능에 대하여 살펴본다.Next, the formation of the "support sealing waterproof film 500" and its tensile strength, and the formation of the "support sealing waterproof wall 520" and its function will be described.

「지지밀폐방수막(500)」은, 격자형태의 부착지지틀(400)과, 그 위에 부착된 보호재일체형합벽방수시트(100)이다. 이는 CIP 지하 지지연속벽(200)에 밀착 설치된다. 격자형태의 부착지지틀(400)은 고정못과 같은 고정수단(420)에 의해 CIP 지하 지지연속벽(200)에 고정된다.The "support sealing waterproof film 500" is a grid-shaped attachment support frame 400 and a protective material integrated wall waterproof sheet 100 attached thereon. It is installed in close contact with the CIP underground support continuous wall 200. The grid-shaped attachment support frame 400 is fixed to the CIP underground support continuous wall 200 by fixing means 420 such as fixing nails.

「지지밀폐방수막(500)」의 배면 공동에 방수액이 혼합된 몰탈(510)이 충진 된다. 충진 된 배면몰탈(510)에 의한 수평압은 「지지밀폐방수막(500)」의 인장강도에 의해 저항·지지된다. 이때 「지지밀폐방수막(500)」의 인장강도는, 보호재일체형합벽방수시트(100)의 압착PE장섬유 부직포(30)에 의한 인장강도이다. 배면몰탈(510)에는 골재로서 굵은 공재가 제외된 모래만으로 이루어진 몰탈이다.A mortar 510 mixed with a waterproofing liquid is filled in the rear cavity of the "paper sealing waterproof film 500". The horizontal pressure caused by the filled back mortar 510 is resisted and supported by the tensile strength of the "support sealing waterproof film 500". At this time, the tensile strength of the "paper sealing waterproof film 500" is the tensile strength of the compressed PE filament nonwoven fabric 30 of the protective material integrated wall waterproof sheet 100. The rear mortar 510 is a mortar composed of only sand excluding coarse common materials as aggregate.

「지지밀폐방수막(500)」과 그 배면 공동에 충진·양생된 배면몰탈(510)이 합쳐진 것이 「지지밀폐방수벽(520)」이다. 또 「지지밀폐방수벽(520)」은 CIP 지하 지지연속벽(200)에 의해 지지된다.The "paper sealing waterproof film 500" and the rear mortar 510 filled and cured in the rear cavity are combined to form the "support sealing waterproof wall 520". In addition, the "support sealing waterproof wall 520" is supported by the CIP underground support continuous wall 200.

이때 「지지밀폐방수막(500)」은, 레미콘으로 현장 타설되는 「지하구조물외벽」의 경계면이다. 「지하구조물외벽」의 방수층이 바로 「지지밀폐방수막(500)」이기 때문이다.At this time, the "paper sealed waterproof film 500" is the boundary surface of the "underground structure outer wall" that is cast in the field with ready-mixed concrete. This is because the waterproof layer of the "outer wall of the underground structure" is the "supporting sealing waterproofing film 500".

「지하구조물외벽의 현장레미콘 타설」 시, 「지지밀폐방수막(500)」으로 된 지지밀폐방수벽(520)」은, 지하구조물외벽의 일 측 거푸집, 즉 외측 거푸집으로서 기능을 하게 된다. 이에 대응된 지하구조물외벽의 타 측 거푸집은, 통상적으로 설치되는 거푸집, 즉 내측 거푸집(320)이다.At the time of ``laying ready-mixed concrete on the outer wall of the underground structure'', the support sealing waterproof wall 520 made of the support sealing waterproof film 500 functions as a formwork on one side of the outer wall of the underground structure, that is, an outer formwork. The other side formwork of the outer wall of the underground structure corresponding to this is a formwork that is normally installed, that is, an inner formwork 320.

외측거푸집으로의 역할을 하기 위해서는 방수시트의 표면인 압착PE장섬유부직포의 파열강도가 9.5-21.3(kgf/cm)이고 인장강력이 경사MD 94-35 위사CD39-18를 유지해야하는 것이 바람직하다In order to serve as an outer formwork, it is desirable that the rupture strength of the compressed PE filament nonwoven fabric, which is the surface of the waterproof sheet, is 9.5-21.3 (kgf/cm) and the tensile strength of the warp MD 94-35 weft CD39-18 is maintained.

또 「지하구조물외벽의 현장 타설 레미콘면」과 접면되는 곳은 「지지밀폐방수막(500)」의 수용성 고무화아스팔트(14)이다. 수용성 고무화아스팔트(14)는 미경화 레미콘면과 친화적이기 때문이다. 이 상태에서 경화되면, 그 부착력 또한 증진되게 된다.In addition, the water-soluble rubberized asphalt 14 of the “supporting sealing waterproofing film 500” is in contact with the “remicon cast in place on the outer wall of the underground structure”. This is because the water-soluble rubberized asphalt 14 is friendly to uncured ready-mixed concrete cotton. When cured in this state, its adhesion is also enhanced.

한편, 압착PE장섬유 부직포(30)의 두께(t)의 65~75%는 수용성 고무화아스팔트(14)가, 그 나머지 두께(t)인 25~35%는 고 점착성 고무화아스팔트(24)가 침투·앵커 결착됨으로써 불투수성의 방수층이 형성됨과 동시에 보호재일체형합벽방수시트(100)의 저항 인장강도가 일체로 거동되어 견고한 지지밀폐방수벽(520)으로서의 기능을 하게 된다.On the other hand, 65-75% of the thickness (t) of the compressed PE filament nonwoven fabric 30 is water-soluble rubberized asphalt 14, and the remaining thickness (t) of 25-35% is high-adhesion rubberized asphalt (24). By penetration and anchoring, an impermeable waterproof layer is formed, and at the same time, the resistance tensile strength of the protective material-integrated wall waterproof sheet 100 behaves integrally, thereby functioning as a solid support sealing waterproof wall 520.

그리고 지지밀폐방수벽(520)의 형성과 관련하여 압착PE장섬유 부직포(30)에 침투·앵커 결착된 상하부의 돌출 수용성 고무화아스팔트(18) 및 돌출 고 점착성 고무화아스팔트(28)의 돌출두께의 합은 2.5~3.0mm가 바람직하다. 또 압착PE장섬유 부직포의 두께(t)와, 그리고 상·하부 층(u)(d)에 침투·앵커된 수용성 고무화아스팔트(14) 및 고 점착성 고무화아스팔트(24)의 두께의 총합이 3.0~3.5mm가 바람직하다.And the protruding thickness of the upper and lower protruding water-soluble rubberized asphalt 18 and the protruding high-adhesion rubberized asphalt 28 penetrated and anchored to the compressed PE long fiber nonwoven fabric 30 in connection with the formation of the support sealing waterproof wall 520 The sum of them is preferably 2.5 to 3.0 mm. In addition, the total thickness of the compressed PE filament nonwoven fabric (t) and the thickness of the water-soluble rubberized asphalt 14 and the high-adhesion rubberized asphalt 24 penetrated and anchored in the upper and lower layers (u) (d) 3.0-3.5mm is preferable.

⒜ 본 발명은 지하구조물외벽 쪽에 방수하던 종래기술과는 달리 CIP 지하 지지연속벽 쪽에 「보호재일체형합벽방수시트」에 의해 방수되는 한편, 「지하구조물외벽」이 아직 축조되지 않은 넓은 공간을 이용하여 CIP 지하 지지연속벽에 「지지밀폐방수막」을 형성하되 이 「지지밀폐방수막」이 「지하구조물외벽」의 경계면이 되게 하면서 동시에 「지지밀폐방수막」을 통해 「지하구조물외벽」과 「CIP 지하 지지연속벽」이 합벽이 되도록 함으로써 「CIP 지하 지지연속벽」의 구조적 강도가 「지하구조물외벽」에 전가 추가·보강되어 「지하구조물외벽」의 구조적 강도 및 그 내구성이 더한층 강화되는 효과가 있고,⒜ The present invention is waterproof by the ``protective material integrated wall waterproof sheet'' on the CIP basement continuous wall side, unlike the prior art that used to waterproof the outer wall of the underground structure, while the CIP using a large space that has not yet been built A ``supported sealing and waterproofing film'' is formed on the supporting continuous walls of the basement, and this ``supporting sealing and waterproofing film'' becomes the boundary of the ``exterior wall of the underground structure,'' and at the same time, through the ``supporting sealing and waterproofing film'', By making the supporting continuous wall” a combined wall, the structural strength of the ``CIP underground supporting continuous wall'' is added and reinforced to the ``outer wall of the subterranean structure'', thereby further enhancing the structural strength and durability of the ``underground structure outer wall''.

⒝ 「지지밀폐방수막」을 「CIP 지하 지지연속벽」에 설치하되 「지하구조물외벽」이 아직 축조되지 않은 넓은 공간을 이용함으로써 그 설치작업이 용이하고 효율적이면서 그 작업공간(B)이 생략될 뿐 아니라 동시에 상기 「지지밀폐방수막」과, 그리고 그 배면 공동에 충진·양생된 콘크리트와 함께 견고한 「지지밀폐방수벽」의 설치도 그 공간을 이용·설치되게 하는 효과가 있으며,⒝ Install the ``supporting sealing and waterproofing membrane'' on the ``CIP underground support continuous wall'', but by using a large space where the ``outer wall of the underground structure'' has not yet been built, the installation work is easy and efficient, and the work space (B) can be omitted. In addition, at the same time, the installation of the ``supporting sealing and waterproofing membrane'' and the sturdy ``supporting sealing and waterproofing wall'' together with the concrete filled and cured in the rear cavity has the effect of allowing the space to be used and installed.

⒞ 또한, 견고하게 형성된 「지지밀폐방수벽」이, 「지하구조물외벽의 현장 타설」시, 합벽거푸집, 즉 외측거푸집으로서의 기능을 하게 하는 효과가 있고,⒞ In addition, the firmly formed ``supporting sealing and waterproofing wall'' has the effect of functioning as a combined wall form, that is, an outer form, when ``casting the outer wall of an underground structure on site,''

⒟ 상기 「지지밀폐방수막」에 있어 배면 공동에 충진된 배면몰탈의 수평압력에 대한 저항 인장강도는, 「보호재일체형합벽방수시트」의 압착PE장섬유부칙포에 의해 지지되고, 격자형태의 부착지지틀(400)과의 일체화 부착력은, 보호재일체형합벽방수시트의 고 점착성 고무화아스팔트(14)에 의해 이루어지며, 또 「지하구조물외벽의 현장 타설 레미콘면」 및 그 양생·경화면에 따른 부착은, 이에 친화적인 수용성 아스팔트에 의해 이루어지면서 증진되는 효과가 있으며,⒟ The tensile strength of the resistance against horizontal pressure of the rear mortar filled in the rear cavity in the above ``supporting sealing waterproofing film'' is supported by the compressed PE filament add-on fabric of the ``protective material integrated wall waterproof sheet'', and adhered in a grid form. The integrated adhesion with the support frame 400 is achieved by the high-adhesion rubberized asphalt 14 of the protective material integrated wall waterproof sheet, and also adheres according to the ``on-site poured ready-mixed concrete surface of the outer wall of the underground structure'' and its curing and landscape. Silver, it is made by water-soluble asphalt that is friendly to it, and has an enhanced effect

본 발명 지하구조물외벽의 축조는, 「bottom up」방식에 의해 단계별로 축조된다. 도3에서 보는바와 같이 단계별 지하구조물외벽의 축조높이는, 1단계에서 h1, 2단계에서 h2, 3단계에서 h3, ····· 가 된다.The construction of the outer wall of the underground structure of the present invention is constructed step by step by a "bottom up" method. As shown in Fig. 3, the construction height of the outer wall of the underground structure at each stage is h1 in the first stage, h2 in the second stage, and h3 in the third stage, ·····.

좀 더 구체적으로 말하면, 지하구조물외벽은, 다음의 과정을 거쳐 축조된다.More specifically, the outer wall of the underground structure is constructed through the following process.

즉, 「CIP 지하 지지연속벽(200)」→「단계별 지지밀폐방수막(500)」→「배면 공동에 배면몰탈(510)충진」→「단계별지지밀폐방수벽(520)」→「단계별 지하구조물외벽」으로 축조된다.In other words, ``CIP underground support continuous wall 200'' → ``Step-by-step support sealing waterproofing film 500'' → ``Filling rear mortar 510 in the rear cavity'' → ``Step-by-step support sealing waterproofing wall 520'' → ``Step-by-step basement It is built as the outer wall of the structure.

여기서, 「CIP 지하 지지연속벽(200)」에 밀착·고정된 「지지밀폐방수막(500)」은, 「격자형태의 부착지지틀(400)」과 「보호재일체형합벽방수시트(100)」으로 이루어진 구조이다.Here, the "supporting sealing waterproofing film 500" that is in close contact with and fixed to the "CIP underground supporting continuous wall 200" is a "lattice-shaped attachment support frame 400" and a "protective material integrated wall waterproof sheet 100". It is a structure made of.

「지지밀폐방수벽(520)」은, 「지지밀폐방수막(500)」과, 그 배면 공동 에 배면몰탈(510)이 충진·경화된 배면 콘크리트 방수층이 이루지는 구조이다. The “support sealing waterproof wall 520” is a structure in which a “support sealing waterproof film 500” and a rear concrete waterproof layer filled and hardened with a rear mortar 510 in the rear cavity are formed.

「지지밀폐방수막(500)」과 「지지밀폐방수벽(520)」 설치작업은, 아직 축조되지 않은 지하구조물외벽의 빈 공간을 이용하여 이루어지는 설치작업이다. 지하구조물외벽의 빈 공간을 이용함으로써 종래와는 달리 별도의 방수작업 공간(B; 1.0m ~ 1.5m)이 필요 없을 뿐만 아니라 이에 의해 「지지밀폐방수막(500)」을 통해 지하구조물외벽과 CIP 지하 지지연속벽(200)이 밀접 되어 일체로 합벽되는 특징이 있게 된다.The installation work of the "supporting sealing and waterproofing film 500" and the "supporting sealing and waterproofing wall 520" is an installation performed by using an empty space on the outer wall of an underground structure that has not yet been built. Unlike the prior art, a separate waterproof work space (B; 1.0m ~ 1.5m) is not required by using the empty space of the outer wall of the underground structure. As a result, the outer wall of the underground structure and the CIP The underground support continuous wall 200 is in close contact with each other and is integrally combined.

「지하구조물외벽」과 「CIP 지하 지지연속벽(200)」이 「지지밀폐방수막(500)」을 통해 일체로 합벽됨으로써 방수가 효율적으로 이루어질 뿐 아니라 「CIP 지하 지지연속벽(200)」의 구조적 강도가 「지하구조물외벽」에 전가 추가·보강되어 「지하구조물외벽」의 구조적 강도 및 그 내구성이 더한층 강화되게 된다.The ``underground structure outer wall'' and the ``CIP underground support continuous wall 200'' are integrated together through the ``support sealing waterproofing film 500'', so that not only is waterproofing efficiently, but also the ``CIP underground support continuous wall 200'' The structural strength is added and reinforced in the "outer wall of the underground structure", and the structural strength and durability of the "outer wall of the underground structure" are further strengthened.

「지지밀폐방수막(500)」의 특성에 대하여 살펴본다.It looks at the characteristics of the "paper sealed waterproof film 500".

첫째, 「지지밀폐방수막(500)」의 배면 공동에 충진된 배면몰탈(510)에 의한 수평압이, 「지지밀폐방수막(500)」에 의해 저항·지지되는 특성이다. 이때 「지지밀폐방수막(500)」의 인장강도는, 보호재일체형합벽방수시트(100)의 압착PE장섬유 부직포(30)에 의한 인장강도이다.First, the horizontal pressure caused by the rear mortar 510 filled in the rear cavity of the "supporting sealing waterproofing film 500" is resistance and supported by the "supporting sealing waterproofing film 500". At this time, the tensile strength of the "paper sealing waterproof film 500" is the tensile strength of the compressed PE filament nonwoven fabric 30 of the protective material integrated wall waterproof sheet 100.

둘째, 「지지밀폐방수막(500)」이 격자형태의 부착지지틀(400)과 일체로 견고하게 부착되는 특성이다. 「지지밀폐방수막(500)」의 그러한 부착력은 보호재일체형합벽방수시트(100)의 고 점착성 고무화아스팔트(20)에 의해 이루어지는 견고한 부착력이다.Second, the "paper sealing waterproof film 500" is a characteristic that is firmly attached integrally with the grid-shaped attachment support frame 400. Such an adhesive force of the "paper sealing waterproof film 500" is a solid adhesive force made by the high-adhesion rubberized asphalt 20 of the protective material integrated wall waterproof sheet 100.

셋째, 「지하구조물외벽의 현장 타설 레미콘(310)면」과 「그 경화면」에 대해 부착되는 특성이다. 「현장 타설 레미콘(310)면」과 「그 경화면」의 부착력은, 레미콘 수화열에 의해 수용성 아스팔트(10)가 더한층 견고하게 부착되는 특성을 갖는다. Third, it is a characteristic that is attached to the "on-site ready-made ready-mixed concrete 310 surface of the outer wall of an underground structure" and "the hardened surface". The adhesion between the "place-place ready-mixed concrete 310" and "the cured surface" has a characteristic that the water-soluble asphalt 10 is more firmly adhered by the heat of hydration of the ready-mixed concrete.

「지지밀폐방수막(500)」의 일련의 특성으로 인해「CIP 지하 지지연속벽(200)」에 직접 방수되는 것이 가능하고, 아직 축조되지 않은 지하구조물외벽의 빈 공간이 이용됨으로써 이러한 직접 방수작업이 용이할 뿐 아니라 별도의 방수작업 공간(B; 1.0m ~ 1.5m)이 필요한 종래기술과는 달리 「지지밀폐방수막(500)」을 통해 일체로 합벽되어 구조적 강도의 전가 및 도심공간의 효율적 경제적 사용이 가능하게 되는 한편, 이러한 모든 것이 보호재일체형합벽방수시트(100)의 특성에 의해 이루지는 특징을 지니게 된다.Due to the series of characteristics of the ``supporting sealing and waterproofing film 500'', it is possible to directly waterproof the ``CIP underground support continuous wall 200'', and this direct waterproofing work by using the empty space of the outer wall of the underground structure that has not yet been built. Unlike the prior art that requires a separate waterproof work space (B; 1.0m ~ 1.5m) as well as easy, it is integrated through the ``supporting sealing waterproofing film 500'' to transfer structural strength and efficient urban space. While economical use is possible, all of these are characterized by the characteristics of the protective material integrated wall waterproof sheet 100.

구조적으로 견고한 격자형태의 부착지지틀(400)에 이러한 특성을 지닌 보호재일체형합벽방수시트(100)가 부착됨으로써 「지지밀폐방수막(500)」이 더한층 구조적으로 보강 강화될 뿐 아니라 그 강화에 의해 「지하구조물외벽의 현장 타설」을 위한 외측 거푸집으로서의 기능을 하게 된다. 외측 거푸집설치가 생략됨으로써 설치시간과 공사비가 절감되는 이점이 있다.By attaching the protective material-integrated wall waterproof sheet 100 having these characteristics to the structurally sturdy grid-shaped attachment support frame 400, the ``support sealing waterproof film 500'' is further structurally reinforced and reinforced by the reinforcement. It functions as an outer formwork for ``Placement of the outer wall of the underground structure on site''. By omitting the installation of the outer formwork, there is an advantage in that installation time and construction cost are reduced.

본 발명 「bottom up」방식에 의한 단계별 지하구조물외벽(200)의 축조높이는 2.5~3.0m가 바람직하다. It is preferable that the construction height of the outer wall 200 of the underground structure at each stage according to the present invention "bottom up" method is 2.5 to 3.0m.

또 토사로 되메움된 종래기술과는 달리 본 발명에는 되메움된 방수작업공간(B)이 생략됨으로써, 즉 합벽이 됨으로써 지하수 탈수로 인한 지반지지력의 불안정과 더불어 주변구조물의 침하현상이 방지되는 이점이 있게 되는 유용한 발명이다.In addition, unlike the prior art backfilled with soil, the backfilled waterproof work space (B) is omitted in the present invention, that is, by becoming a combined wall, it is advantageous in that the subsidence of surrounding structures is prevented along with instability of the ground bearing capacity due to dehydration of groundwater. It is a useful invention to have.
