Abstract

The present invention relates to a permanently usable waterproof peristyle retaining wall system, which completely blocks water in a peristyle retaining wall method greatly used in an underground structure construction and can be used as a permanent body for an outer wall of an underground structure; and a constructing method thereof. According to the present invention, in the conventional peristyle retaining wall method for an underground excavation work in rivers or coastal areas with high underground water level, water leakage frequently occurs in a pile joint part of a peristyle retaining wall, and causes additional costs for blocking water, an increase in a construction period, and a secondary damage occurring probability, such as excavation back subsidence due to water leakage. However, according to the present invention, a near-perfect water blocking effect is exhibited during excavation by complete improvement (mortar or concrete) of a water blocking plate for blocking water at a joint part of a peristyle retaining wall pile (wall forming member) and the joint part such that stable and economically feasible construction can be performed. Also, a temporary retaining wall is provided with a rebar reinforcing connector to be used as a permanent wall due to complete water blocking, thereby reducing the thickness of a building underground wall to additionally secure an underground space.

Description

건물 지하벽체로 사용 가능한 차수 주열식 흙막이벽체시스템 및 그 시공방법{Retaining Wall System usable as building underground wall and Method for constructinging the same}Retaining Wall System usable as building underground wall and Method for constructing the same}

본 발명은 건물지하벽체로 사용 가능한 차수 주열식 흙막이벽체시스템과 그 시공방법에 관한 것으로 구체적으로는 지하구조물 공사시 많이 사용하는 주열식 흙막이 공법에서 차수가 완벽히 가능하도록 하고 지하건축물 외벽의 영구체로도 활용할 수 있도록 하기 위한 차수 주열식 흙막이벽체시스템과 그 시공방법에 관한 것이다.The present invention relates to an ordering column type earthen wall system that can be used as a building basement wall and a construction method thereof. Specifically, the ordering method is completely possible in the main column type earthen blocking method used in the construction of underground structures, and also as a permanent body of the outer wall of an underground building. It relates to an ordering column type earth barrier system to be utilized and its construction method.

지하수위가 존재하는 지반의 지하 굴착시 적용되는 종래의 주열식 흙막이 기술은 도 1과 같이 지하수 차단을 위하여 주열식 흙막이 벽체 배면에 별도의 차수그라우팅을 실시하거나 도 2와 같이 주열식 말뚝을 겹침 시공하여 굴착배면의 지하수가 굴착측 내부로 유입되지 못하도록 하는 방법이다. 굴착 배면에 차수 그라우팅을 실시하는 방법은 지반조건에 따라 차수 그라우팅의 효과를 보기 어려운 경우가 많고 장기지속적인 차수효과를 기대할 수 없는 경우가 많아 시공 중 또는 사용 중에 누수로 인하여 추가적인 차수 그라우팅을 실시하거나 차수를 위한 별도의 보조공법 또는 유지보수공법을 적용하는 경우가 대부분이며 그 효과도 크지 않은 편이어서 지하구조물 벽체의 내구성을 크게 저하시킬 수 있다. 또한, 주열식 말뚝을 겹침 시공하여 차수하는 방법에 있어서 주열 말뚝의 시공 수직도가 불량하거나 말뚝의 건전도가 불량한 경우 그리고 말뚝과 말뚝의 이음부에 존재하는 굴착 토사 잔여물 등이 있는 경우 등의 원인으로 벽체 자체에서도 누수가 되는 경우가 많아 추가적인 차수 대책이 필요한 것이 현실이다. 또한, 기존의 주열식 흙막이 벽체는 가설이므로 시공되는 본 건축물의 벽체는 가시설 내측의 굴착측에 별도로 형성된다. 즉, 본 건축물의 지하외벽에는 별도의 가시설벽체가 형성되는 것으로 지하공간의 활용이 그만큼 제한되게 된다.The conventional main column type earthen blocking technology applied when excavating the ground where the groundwater level exists is to perform a separate order grouting on the back of the main column type earthen wall to block the groundwater as shown in Fig. 1 or overlap construction as shown in Fig.2. This is a method to prevent groundwater from flowing into the inside of the excavation side. The method of performing order grouting on the back of the excavation is often difficult to see the effect of order grouting depending on the ground conditions and a long-term continuous ordering effect cannot be expected.Therefore, additional order grouting is performed or ordered due to leakage during construction or use. In most cases, a separate auxiliary method or maintenance method is applied for the purpose, and the effect is not so great that the durability of the wall of the underground structure can be greatly reduced. In addition, in the method of overlapping and ordering the main row piles, if the construction verticality of the main row piles is poor or the health of the piles is poor, and if there are excavated soil residues present in the joint between the piles and the piles. As a cause, there are many cases of leakage from the wall itself, so additional measures are required. In addition, since the existing main column type earthen wall is temporary, the wall of this building to be constructed is separately formed on the excavation side inside the temporary facility. In other words, a separate temporary facility wall is formed on the outer basement wall of this building, which limits the use of the underground space.

상기와 같은 현재의 주열식 흙막이 공법은 차수그라우팅 후 굴착을 실시하지만 시공 중 지하수 유출이 발생하여 추가적인 차수를 위하여 공사기간이 늘어나고 공사비가 증가되는 등의 문제가 필연적으로 발생하고 있으며 2차적으로 누수로 인한 굴착 배면 지반의 침하 발생 가능성도 매우 높다. 이러한 사실들은 최근 지하안전관리에 관한 특별법에서 주변지반의 침하를 방지하기 위하여 지하수를 펌핑하지 못하게 하는 점에 역행하는 사실이어서 조속히 지하수 누수(펌핑)를 방지하기 위한 대책이 사회적으로 요구되고 있는 점에 있어서 특히 본 특허기술의 개발이 중요하다. 그리고 가설 흙막이 벽체를 본 구조물로 사용할 수 없을 경우에는 지하공간 활용성이 낮아지는 단점도 있는데 본 특허기술에서는 이러한 부분도 보완되게 되어 장점이 큰 기술이다.The current main column type earth-blocking method as described above performs excavation after order grouting, but groundwater leakage occurs during construction, which inevitably causes problems such as an increase in construction period and construction cost for additional construction. The possibility of subsidence of the back ground due to excavation is also very high. These facts are contrary to the fact that the recent Special Act on Underground Safety Management prevents the pumping of groundwater to prevent subsidence of the surrounding ground, so measures to prevent groundwater leakage (pumping) as soon as possible are socially required. In particular, the development of this patented technology is important. In addition, if the temporary earthen wall cannot be used as the main structure, there is a disadvantage that the utilization of the underground space is lowered. In this patented technology, these parts are also complemented, which is a great technology.
