조립식 강널말뚝 우물통 가물막이 설치구조 및 그 방법{Construction structure of open caisson cofferdam using assembling sheet pile and it's method}Construction structure of open caisson cofferdam using assembling sheet pile and it's method

본 발명은 조립식 강널말뚝 우물통 가물막이 설치구조 및 그 방법에 관한 것으로서, 보다 상세하게는 강널말뚝에 의해 우수한 차수성을 갖고, 설치 및 해체가 보다 용이하며, 자재수급과 제작이 용이할 뿐만 아니라 자재의 재활용이 우수하게 이루어지는 조립식 강널말뚝 우물통 가물막이 설치구조 및 그 방법에 관한 것이다. The present invention relates to a prefabricated steel sheet pile wells faucet installation structure and method, and more particularly, has a superior degree of orderability by the steel sheet pile, easier to install and dismantle, easy to supply and manufacture materials The present invention relates to a prefabricated steel sheet pile well pail installation structure and method for excellent recycling of materials.

일반적으로 육상조건에서 건설되는 교량보다 강이나 바다를 횡단하는 교량은 수상에서 공사를 하여야 함으로 작업에 제약조건이 많고, 하부기초의 수중공사가 불가피함으로 공사비가 고가이다.In general, bridges that cross rivers or seas are more expensive than bridges constructed under land conditions, and therefore the construction cost is high because the construction of the lower foundation is inevitable.

또한, 최근에는 수중공사를 줄이기 위해 교각간의 길이를 장경간화함으로써 하부기초 규모가 커짐으로 하부기초의 형식 및 가설공법에 따라 많은 공사비 차이를 보이고 있다.In addition, in recent years, the length of the pier is increased by the length of the bridge to reduce the underwater construction to increase the base of the lower foundation, showing a lot of construction cost differences depending on the type and construction method of the lower foundation.

일반적으로 수심이 낮은 곳은 흙으로 가도와 축도를 축조하여 하부를 시공하 므로 공사에 큰 지장이 없으나, 수심이 깊은 강이나 바다에서는 가도와 축도가 어려워 하부기초의 시공에는 물막이공법을 병행한다.In general, since the lower part is constructed with highways and shafts made of soil, there is no major obstacle in the construction, but the highways and shafts are difficult in deep rivers or seas, and the water barrier construction is performed at the bottom foundation.

하부기초의 지지층인 암반층이 지면에서 바로 존재하는 경우와 암반층 위에 토사가 두껍게 존재하는 경우에 따라 하부기초형식 및 물막이공법이 다르게 된다.The lower foundation type and water barrier method are different depending on the case where the rock layer, which is the supporting layer of the lower foundation, is present directly on the ground and when the soil is thickly present on the rock layer.

암반층이 바로 존재하는 경우는 거치식 우물통기초와 직접기초가 적용되며, 토사층이 깊이 존재하는 경우에는 말뚝기초와 침설식 우물통이 적용된다.In the case where the rock layer exists immediately, the fixed well base and the direct foundation are applied, and when the soil layer is deep, the pile foundation and the submerged well base are applied.

거치식 및 침설식 우물통기초에는 일반적으로 강재거푸집을 이용하여 물막이를 하며, 말뚝기초인 경우는 강널말뚝공법과 피씨하우스(PC HOUSE)공법이 주로 적용된다.In the case of stationary and submerged well wells, the water is generally formed using steel formwork, and in the case of pile foundations, the steel sheet pile method and the PC house method are mainly applied.

강재거푸집을 이용하는 물막이는 수심보다 높게 육상에서 강재 우물통 거푸집을 제작하여 수상 운반 및 기초위치에 침설 거친시킨 후 거푸집 내부에 콘크리트를 타설하여 시공하는 공법으로 강재 거푸집은 사장시키는 것이며, 강널말뚝공법은 바지선 위에서 강널말뚝을 소요깊이만큼 지반에 박아 측면 및 하부의 내부유입수를 차단하여 말뚝의 상단에 설치되는 기초슬래브를 육상조건에서 시공하는 공법이며, 피씨하우스공법은 말뚝의 상단이 수면위로 노출이 되도록 하여 기초슬래브 시공이 육상작업이 되도록 하는 공법으로 조수간만의 차가 많이 발생하는 바다에 주로 적용한다.The water block using steel formwork is a method of making steel well formwork on land higher than water depth, roughening it in water transport and foundation position, and then placing concrete inside the formwork to install steel formwork. It is a method of constructing the foundation slab installed on the top of the pile under the ground condition by cutting the channel pile on the ground to the required depth on the barge and blocking the inflow of the inside and the bottom of the pile. This method is to apply the basic slab construction to the land work. It is mainly applied to the sea where the difference between tides occurs.

그러나, 이러한 종래의 물막이공법은 많은 건설비용과 작업공기가 발생하는 문제점이 있는 것인바, 상기 강널말뚝공법은 수상에서 토사층에 강널말뚝을 근입시켜야 하므로 항타비용과 많은 작업시간이 소요되는 문제점이 있었고, 침설식 우물 통은 불필요한 강재거푸집 사용으로 공사비가 고가이며, 피씨하우스공법은 강널말뚝공법의 말뚝기초가 지반에 매입되어 지반이 수평변위에 저항하는 반면, 피씨하우스공법의 말뚝기초는 수면에 노출이 되어 지반의 수평저항에 효과가 없어 강널말뚝공법의 말뚝개수보다 더 많은 말뚝을 박아야 하므로 기초규모가 필요 이상으로 비대하며 기초의 노출로 미관이 좋지 않다는 문제점이 있었다.However, such a conventional water barrier method has a problem that a lot of construction cost and work air occurs, the steel sheet pile method has a problem that the driving cost and a lot of time is required because the steel sheet piles must be incorporated into the soil layer in the water surface The construction cost is high due to the unnecessary use of steel formwork for the submerged well bucket, and the PC house method is the pile foundation of the steel sheet pile method is embedded in the ground, and the ground resists the horizontal displacement, while the pile foundation of the PC house method is exposed to the water surface. Since there is no effect on the horizontal resistance of the ground, it is necessary to put more piles than the number of piles in the steel sheet pile method, so the basic scale is larger than necessary and the aesthetics are not good due to the exposure of the foundation.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 강널말뚝에 의해 우수한 차수성을 갖고, 설치 및 해체가 보다 용이하며, 자재수급과 제작이 용이할 뿐만 아니라 자재의 재활용이 우수하게 이루어지는 조립식 강널말뚝 우물통 가물막이 설치구조를 제공함에 그 목적이 있다.The present invention is to solve the problems as described above, prefabricated steel sheet pile made of a good degree of orderability by the steel sheet pile, easier to install and dismantle, easy to supply and manufacture materials and excellent recycling of materials The purpose of this is to provide a well structure for the well bucket closure.
