강재 케이싱 토류벽 구조와 그 시공방법 및 이를 이용한 하천제방정비와 도로확장 공법Steel casing earth wall structure and its construction method, river bank maintenance and road extension method

본 발명은 강재 케이싱 토류벽 구조와 그 시공방법 및 이를 이용한 하천제방정비와 도로확장 공법에 관한 것으로, 보다 상세하게는 토류벽으로 고인장·고강도의 강재 케이싱을 이용함으로써 케이싱의 굴진을 위한 굴착시 암반층이 존재하더라도 암반의 파쇄에 수반되는 충격과 진동을 견딜 수 있을 뿐만 아니라, 균열이나 파손 방지에 강한 강성구조로서 지하수 유입차단에 효과적이며, 하천 단면적의 증가로 인한 수중생물의 서식처의 증대로 인해 친환경적인 공법이 가능하고, 기존의 도로확장 시공시 추가적인 도로부지와 차량통행의 차단이 필요하지 않은 강재 케이싱 토류벽 구조와 그 시공방법 및 이를 이용한 하천제방정비와 도로확장 공법에 관한 것이다.The present invention relates to a steel casing earth wall structure and its construction method, and to river dike maintenance and road expansion method using the same, and more specifically, the rock bed when excavation for excavation of the casing by using a high tension, high strength steel casing as the earth wall It is not only able to withstand the impact and vibration associated with rock crushing, but it is also a rigid structure that is resistant to cracks and breakage, and is effective in blocking groundwater inflow and environmentally friendly due to the increase of habitats of aquatic organisms due to the increase of river cross-sectional area. The present invention relates to a steel casing earth wall structure that can be constructed and that does not require additional road site and vehicle traffic, and its construction method, and the river dike maintenance and road extension method using the same.

일반적으로 하천제방 정비공법에는 하천제방의 유실을 방지하기 위하여 인공구조물을 이용하거나 잡석 쌓기와 같은 공법이 적용되고 있다.In general, in order to prevent the loss of river embankments, construction methods such as using artificial structures or stacking rubble are applied.

인공구조물을 이용하는 하천제방 정비공법은 하상을 굴착하여 하측에 기초 콘크리트를 타설하고 제방 사면에 매트를 설치한 후, 기초 콘크리트의 상측과 매트의 상측에 돌망태를 쌓아 올리는 공법이다.The river dike maintenance method using artificial structures is a method of excavating the riverbed, placing the foundation concrete on the lower side, installing the mat on the slope of the bank, and then stacking the gabion on the upper side of the foundation concrete and the upper side of the mat.

또한, 잡석 쌓기는 하상을 굴착하여 기초 콘크리트를 타설하고, 이 기초 콘크리트 주위를 밑다짐을 하며, 제방의 사면을 따라 입도가 작은 잡석으로 뒷채움을 하면서 상당한 규모의 자연석을 쌓아 올려 제방을 보강하여 정비하는 공법이다.In addition, rubbish stacking excavates the foundation, places foundation concrete around the foundation concrete, backfills small rubble along the slope of the embankment, builds a substantial scale of natural stone, reinforces the dike and repairs it. It is a technique.

그러나, 상기와 같은 공법들은 돌망태나 잡석 또는 자연석으로 제방을 보강·정비하므로 공사 후 수중생물의 서식처 및 산란 장소를 축소시키게 되고 하천 환경을 해치게 되는 문제점이 있다.However, the above methods have a problem of reducing the habitat and spawning place of the aquatic organisms after construction and thus damaging the river environment because the dike is reinforced and repaired with gabions, rubble or natural stones.

또한, 일반적으로 시공되는 도로확장공법은 단순히 확장구간만큼의 도로폭을 성토·절토하거나, 확장하고자하는 폭만큼의 위치에 토류벽을 설치하여 토류벽과 기존 도로 사이를 성토하는 방법으로 확장구간을 신설하였다.In addition, the road extension method, which is generally constructed, has newly established an extension section by simply laying and cutting road widths as much as the extension section, or by installing an earth wall at a position that is intended to be expanded. .

그러나, 확장구간만큼의 도로폭의 단순한 성토·절토는 성토부나 절토부의 안정을 위해 성토부나 절토부의 구배를 고려해야 하기 때문에 더 넓은 면적의 도로부지가 필요하거나 공사비가 증가되는 경향이 있었고, 도로확장 시공시 차량통행의 차단이나 노선변경은 불가피하였으며, 종래의 토류벽의 시공방법도 어느 정도 문제점이 있었다.However, the simple fill and cut of the road width as much as the extended section had to consider the slope of the cut section and the cut section for the stability of the fill section and the cut section. It was unavoidable to block the city traffic or change the route, and there was a problem in the conventional construction method of the earth wall.

따라서, 본 발명에서는 하천제방 정비와 도로확장을 위해 강재 케이싱 토류벽을 이용하게 되는데, 일반적으로 연약지반이나 매립성 토지 또는 지하수의 유출이 심한 지반이나 도심지 구간 굴착공사에서 구조물 기초공사와 주변 건물의 보호 및 공사작업현장의 안전을 확보하기 위해 토류벽이 설치되고 있고, 이러한 토류벽은 지하공사를 할 때 굴착사면의 안정 및 지하수 유입의 차단을 위해 설치되는 가설구조물로서, 대표적인 공법으로는 토류판공법, SHEET PILE(널말뚝)공법, CIP공법, SCW공법 및 지하연속벽공법 등이 있다.Therefore, in the present invention, the steel casing earth wall is used for river bank maintenance and road extension. In general, the foundation of the structure and the protection of the surrounding buildings in the ground or urban section excavation work where the outflow of soft ground or landfill land or groundwater is severe. And the earth wall is installed to secure the safety of the construction work site, and this earth wall is a temporary structure that is installed to stabilize the excavation slope and block the groundwater inflow during underground construction. Representative construction methods include the earth plate method and the sheet pipe. (Stack pile) method, CIP method, SCW method and underground continuous wall method.

상기 토류판 공법은 다수개의 토류판과 H-PILE을 이용하는 공법으로 지하의 굴착할 부분에 H-PILE을 일정 간격으로 박아 넣고, H-PILE 사이에 나무판재인 토류판을 끼워넣어 배면의 토사를 지지하며, H-PILE의 지지를 위한 지보공을 설치하는 공법이다.The earth plate method is a method using a plurality of earth plate and H-PILE drive H-PILE at regular intervals to be excavated in the basement, and sandwich the earth plate of the wood plate between the H-PILE to support the earth and sand on the back, It is a method to install jibo ball for supporting H-PILE.

또한, SHEET PILE 공법은 SHEET PILE을 수직으로 지중에 박아 넣고 이어서 단부의 연결부에 다른 SHEET PILE의 단부를 끼워 맞춰 지중에 박아넣는 것을 반복함으로써 토류벽을 시공하는 공법이다.In addition, the SHEET PILE method is a method of constructing the earth wall by repeatedly inserting the SHEET PILE into the ground vertically and then fitting the end of the other SHEET PILE to the connecting portion of the end and inserting the end into the ground.

그리고, CIP 공법은 AUGER로 지중에 구멍을 뚫은 다음 그 구멍에 철근망이나 H-PILE을 입설하고 콘크리트나 시멘트풀을 타설하여 연속된 콘크리트 기둥을 만들어 나가는 공법으로, 굴착할 부분 사방을 콘크리트벽으로 만든 다음 붕괴를 막기 위하여 콘크리트벽을 지탱할 버팀보를 설치한 상태에서 굴착을 하는 방법이다.The CIP method is a method in which a hole is drilled in the ground with an AUGER, and a reinforcing bar or H-PILE is placed in the hole, and concrete or cement paste is poured to form a continuous concrete column. After the construction, they are excavated with a brace to support the concrete wall to prevent collapse.

또한, SCW 공법은 축을 세 개 가진 AUGER로 지하 연속벽을 만들어 나가는 공법으로 시공방법은 상기 CIP와 거의 동일하다.In addition, the SCW method is a method of making an underground continuous wall with an AUGER having three axes, and the construction method is almost the same as the CIP.

그러나, 이러한 종래의 토류벽 시공방법은 주로 토사지반이나 토사 성토층에 적용 가능하고, 사석층이나 전석 토사층에 시공시에는 Pre-Boring공법을 시행하여야 하며, 암반층에는 시공이 어려운 문제점이 있었다.However, the conventional earth wall construction method is mainly applicable to the soil ground or earth and sand soil layer, and when the construction on the sandstone or all-earth soil layer, the pre-boring method should be performed, and the rock layer has a difficult construction.

In addition, it is not suitable for being used as a part of a later construction, and it is necessarily accompanied by demolition work.

또한, 지중에 콘트리트를 타설하는 방식의 토류벽의 경우 지중의 콘크리트의 품질관리에 어려움이 많고, 토류벽 시공후 지하수 유출시 보수 보강이 어려운 문제점이 있었다.In addition, in the case of soil wall in the way of placing concrete in the ground, it is difficult to control the quality of concrete in the ground, and it is difficult to repair and reinforce the groundwater leakage after the construction of the ground wall.

상기와 같이 구성된 본 발명의 바람직한 실시예를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings a preferred embodiment of the present invention configured as described above are as follows.

본 발명인 강재 케이싱 토류벽의 기본 구조는 도 1 및 도 2에 도시된 바와 같이, 일정 길이와 높이로 제작된 선단부 케이싱(20,21)과 상기 선단부 케이싱(20,21)과 동일한 길이 및 형상의 중간 연결부 케이싱(30,31)이 상하방향으로 상호 결합하되, 선단부 케이싱(20,21)과 중간 연결부 케이싱(30,31) 간의 결합부위는 용접이음(41)이나 기계적이음으로 처리하고, 용접이음(41)의 경우의 케이싱 각각의 상·하단에는 인접하는 케이싱과 대응되게 용접홈(40)이 형성되도록 함이 바람직하다.The basic structure of the steel casing earth wall of the present invention is the middle of the same length and shape as the front end casing (20, 21) and the front end casing (20, 21) made of a predetermined length and height, as shown in Figs. Connection casing (30, 31) is mutually coupled in the vertical direction, the coupling portion between the front end casing (20, 21) and the intermediate connection casing (30, 31) is treated with a weld joint 41 or a mechanical joint, weld joint ( At the upper and lower ends of the casing in the case of 41), the welding groove 40 is preferably formed to correspond to the adjacent casing.

이러한 선단부 케이싱(20,21)과 중간 연결부 케이싱(30,31)으로 이루어진 케이싱 구체(10)가 일정한 간격을 유지하면서 이중으로 설치되어 토류벽을 형성하고, 필요한 경우 가로 지지보(23)를 일정 간격으로 선단부 및 중간 연결부 내·외벽 케이싱(20,21,30,31) 사이에 고정설치하며, 상기 선단부 케이싱의 하단(22)은 V자형상이나 역사다리꼴형상으로 가공제작함이 바람직하다.Casing sphere 10 consisting of the tip casing (20, 21) and the intermediate connecting casing (30, 31) is installed in a double while maintaining a constant interval to form a earth wall, if necessary, the horizontal support beam (23) at regular intervals Therefore, the front end portion and the intermediate connection portion is fixedly installed between the inner and outer wall casings (20, 21, 30, 31), it is preferable that the lower end 22 of the front end casing is processed into a V-shaped or inverted trapezoidal shape.

한편, 도 3에 도시된 바와 같이, 이러한 강재 케이싱 토류벽의 시공방법을 설명하면 다음과 같다.On the other hand, as shown in Figure 3, when explaining the construction method of the steel casing earth wall as follows.

우선, 현장 여건에 적합하게 일정 길이와 높이로 제작된 선단부 케이싱(20,21)을 토류벽의 내·외벽을 형성할 수 있게 이중으로 토류벽 설치위치에 거치한다(도3a). 여기서, 상기 이중의 선단부 내·외벽 케이싱(20,21)은 케이싱의 지중으로의 굴진시 외부의 토압이나 수압과 같은 지중 응력에 충분히 견디고 지하수 유입 차단에 효과적이며 내·외벽 케이싱 사이의 암반을 파쇄하는 경우에 충격 및 진동으로부터 케이싱 벽체의 균열 및 손상을 방지하기 위해 일정한 두께의 고인장·고강도 강판을 현장여건을 고려하여 사용하여야 한다.First, the front end casings 20 and 21 manufactured to have a predetermined length and height to fit the site conditions are mounted on the earth wall installation position in duplicate so as to form the inner and outer walls of the earth wall (FIG. 3A). Here, the double tip inner and outer wall casings 20 and 21 are sufficiently resistant to underground stresses such as external earth pressure or water pressure when excavating into the ground of the casing, and are effective in blocking groundwater inflow, and fracture the rock between the inner and outer wall casings. In order to prevent cracking and damage of casing wall from impact and vibration, high tensile and high strength steel plates of constant thickness should be used in consideration of site conditions.

또한, 상기 케이싱은 도 1의 일실시예에서 도시된 바와 같이, 본 발명의 케이싱을 이용한 토류벽이 시공되는 단면형상 일체로 제작되어 선단부 내·외벽 케이싱(20,21)이 거치될 수도 있고, 일체로 거치하는 경우 케이싱의 운반이나 거치에 작업상의 문제점이 발생하는 경우에는 구간을 나누어 구간별로 선단부 케이싱(20,21)을 제작하여 이중으로 거치하면 된다.In addition, as shown in the embodiment of Figure 1, the casing, the earth wall using the casing of the present invention is integrally manufactured in a cross-sectional shape is constructed, the inner and outer wall casing (20, 21) of the front end may be mounted, integral In the case of mounting, if the problem occurs in the transport or mounting of the casing, it is necessary to produce the front end casing (20, 21) for each section by dividing the section and double mounting.

나아가, 상기 선단부 케이싱의 하단 toe(22)는 케이싱의 지중으로의 굴진시 굴진이 용이하도록 V자형상이나 역사다리꼴형상으로 가공제작함이 바람직하다.Further, the lower end toe 22 of the tip casing is preferably fabricated into a V-shape or an inverted trapezoidal shape so that the casing can be easily excavated to the ground.

다음으로, 상기 선단부 내·외벽 케이싱(20,21) 사이의 지반을 굴착하면서 굴착토를 외부로 반출하면, 굴착과 동시에 선단부 케이싱(20,21)은 그 자중으로 굴착 바닥면(50)까지 침하굴진하게 되고, 굴착에 의한 지반의 수직 굴착면(51)은 굴착과 동시에 상기 내·외벽 케이싱(20,21)에 의해 지지되어 외부로 노출되지 않으므로 굴착면의 붕괴 방지가 가능하게 되고(도3b), 필요하다면 상기 내·외벽 케이싱(20,21)의 지지를 위한 강지보공을 지중에 설치하여 굴착면의 붕괴와 토류벽의 전도를 방지할 수도 있다. 또한, 이 때 필요하다면 상기 선단부 내·외벽 케이싱(20,21) 사이의 간격을 유지하고 외부의 지중 응력에 견디기 위해 가로 지지보(23)를 일정 간격으로 선단부 내·외벽 케이싱(20,21) 사이에 고정설치하고, 구간별로 나누어 선단부 케이싱(20,21)을 제작하여 굴착이 이루어지는 경우에는 케이싱의 길이방향 양단부에서도 지중 응력에 견딜 수 있고 차수가 가능하도록 내·외벽 케이싱을 폐합시키는 형태로 선단부 케이싱(20,21)을 제작하여야 하고, 구간별 굴착시 인접하는 폐합된 선단부 케이싱(20,21) 사이에는 지하수 유입 차단을 위해 실런트가 주입될 수도 있고, 인접하는 폐합된 선단부 케이싱(20,21) 양단부를 절단 개방시켜 인접하는 구간별 선단부 내·외벽 케이싱(20,21) 사이에 강판을 덧대어 용접이음할 수도 있다.Next, when the excavated soil is taken out while excavating the ground between the tip inner and outer wall casings 20 and 21, the tip casing 20 and 21 sinks to the excavation bottom surface 50 at the same time as the excavation. As the excavation, the vertical excavation surface 51 of the ground by excavation is supported by the inner and outer wall casings 20 and 21 at the same time as excavation and is not exposed to the outside, thereby preventing the collapse of the excavation surface (Fig. 3B). If necessary, it is possible to prevent the collapse of the excavation surface and the fall of the earth wall by installing a stiff ground for supporting the inner and outer wall casing (20, 21) in the ground. At this time, if necessary, the inner and outer wall casings 20 and 21 at the predetermined intervals of the horizontal support beams 23 at regular intervals to maintain the gap between the inner and outer wall casings 20 and 21 and to withstand the external stresses. If the excavation is made by disposing the tip casings 20 and 21 by dividing the sections by sections, the tip is formed in such a way that the inner and outer wall casings are closed so that they can withstand the ground stress at both ends of the casing in the longitudinal direction and can be ordered. Casing (20, 21) should be manufactured, and sealant may be injected to block groundwater inflow between adjacent closed tip casing (20, 21) when excavation by section, adjacent closed tip casing (20, 21) 2) The both ends may be cut open so that a welded joint may be formed by applying a steel sheet between the inner and outer wall casings 20 and 21 of the adjacent sections.

여기서 지반 굴착작업은 선단부 내·외벽 케이싱(20,21) 사이에서 이루어지고, 선단부 내·외벽 케이싱(20,21) 사이의 간격은 굴착이 가능한 최소한의 공간만 확보되면 된다. 따라서, 굴착방식은 인력굴착이나 Short Boom/ Short Arm 굴삭기를 이용한 기계식 굴착으로 하는 것이 시공성이 우수하다.Here, the ground excavation work is made between the inner and outer wall casings 20 and 21 at the tip portion, and the space between the inner and outer wall casings 20 and 21 at the tip portion is only required to secure a minimum space for excavation. Therefore, the excavation method is excellent in workability by the manpower excavation or mechanical excavation using the Short Boom / Short Arm Excavator.

더불어, 수직 굴착면(51)의 붕괴방지와 케이싱 외부에서 작용하는 지중 응력의 분산 및 케이싱과 수직 굴착면(51) 사이의 마찰감소를 위해 케이싱과 수직 굴착면(51) 사이의 여굴부(52)에는 세골재나 조골재 등의 충진재(53)를 채우게 되고, 현장 여건상 특히 지하수 유출이 심할 경우에는 토사나 점토로 충진하여 지하수 유입을 저감시키는데, 이러한 충진은 상기 선단부 내·외벽 케이싱(20,21) 각각의 외면에 상기 충진재(53)를 굴착 전에 미리 쌓아 놓아두면 굴착시 여굴부(52)의 발생과 동시에 자연스럽게 충진재(53)가 여굴부(52)로 흘러 들어가게 되는 것이다.In addition, the excavation portion 52 between the casing and the vertical excavation surface 51 for preventing the collapse of the vertical excavation surface 51 and the dispersion of underground stresses acting outside the casing and the friction between the casing and the vertical excavation surface 51 is reduced. ) Is filled with fillers 53 such as fine aggregates and coarse aggregates, and in case of severe groundwater outflow, the groundwater inflow is reduced by filling with soil or clay, and such filling is the inner and outer wall casings (20, 21). When the filler 53 is stacked in advance on each outer surface before excavation, the filler 53 flows naturally into the excavation portion 52 at the same time as the excavation portion 52 is generated during the excavation.

그 다음으로, 상기 선단부 내·외벽 케이싱(20,21)의 높이보다 일정 정도 적은 심도의 굴착 및 선단부 내·외벽 케이싱(20,21)의 굴진이 완료되면, 상기 선단부 내·외벽 케이싱(20,21)의 상부에 동일한 길이 및 형상의 중간 연결부 내·외벽 케이싱(30,31)을 설치한 후 결합부위를 용접이음(41) 처리함이 바람직하나, 지하수 유입 차단이 가능하다면 선단부와 중간 연결부 내·외벽 케이싱(20,21,30,31) 간의 이음은 용접에 제한되는 것은 아니고 기계적이음도 가능할 것이다(도3c).Next, when the excavation of the depth and the excavation of the tip inner and outer wall casing (20, 21) to a certain degree less than the height of the tip inner and outer wall casing (20, 21) is completed, the tip inner and outer wall casing (20, 21) After installing the inner and outer wall casings 30 and 31 of the same length and shape in the upper part, it is preferable to process the welded joint 41 by the joint, but if it is possible to block the inflow of groundwater, The joints between the outer wall casings 20, 21, 30 and 31 are not limited to welding but mechanical joints may be possible (Fig. 3c).

상기에서 선단부 내·외벽 케이싱(20,21)의 높이보다 일정 정도 적은 심도로 굴착하는 것은 선단부와 중간 연결부 내·외벽 케이싱(20,21,30,31) 간의 용접이음(41)을 용이하게 지상에서 작업하기 위함이다.Excavation at a depth smaller than the height of the inner and outer wall casings 20 and 21 at the tip portion facilitates the welding joint 41 between the inner and outer wall casings 20, 21, 30 and 31 at the tip portion. To work on

여기서, 선단부 내·외벽 케이싱(20,21)과 중간 연결부 내·외벽 케이싱(30,31) 간의 용접이음(41)은 케이싱 구체(10)의 강도와 동등 이상의 강도 발현이 가능하도록 하여야 하고, 이를 위해 케이싱 각각의 상·하단에는 인접하는 케이싱과 대응되게 용접홈(40)이 형성되도록 제작한다.Here, the weld joint 41 between the inner and outer wall casings 20 and 21 of the tip portion and the inner and outer wall casings 30 and 31 of the intermediate portion should be capable of exhibiting strength equal to or greater than that of the casing sphere 10. The upper and lower ends of each of the casings are manufactured so that the welding grooves 40 are formed to correspond to the adjacent casings.

나아가, 선단부 내·외벽 케이싱(20,21)과 중간 연결부 내·외벽 케이싱(30,31) 간의 용접이음(41)이 완료되면, 다시 상기 선단부 내·외벽 케이싱(20,21) 사이의 지반을 굴착하고 굴착과 동시에 내·외벽 케이싱 구체(10)는 굴착 바닥면(50)까지 침하굴진한다(도3d).Further, when the weld joint 41 between the inner and outer wall casings 20 and 21 of the tip portion and the inner and outer wall casings 30 and 31 of the intermediate portion is completed, the ground between the inner and outer wall casings 20 and 21 of the tip portion is again formed. Excavation and at the same time as the excavation, the inner and outer wall casing sphere 10 sinks down to the excavation bottom surface 50 (FIG. 3D).

한편, 상기 선단부 내·외벽 케이싱(20,21)과 중간 연결부 내·외벽 케이싱(30,31)들은 토류벽의 시공 목적상 높이에 비해 횡방향으로 길이가 긴 구조로 제작함이 바람직하고, 도면에 도시된 직선형에 제한되는 것은 아니고 토류벽의 설계 형상에 따라 곡선형 또는 직선과 곡선이 혼용된 복합형으로 제작될 수도 있다.On the other hand, the front end inner and outer wall casing (20, 21) and the intermediate connection inner and outer wall casing (30, 31) is preferably made of a structure having a long length in the transverse direction compared to the height for the purpose of the earth wall construction, The present invention is not limited to the illustrated linear form, and may be manufactured in a curved form or a composite form in which straight lines and curves are mixed according to the design shape of the earth wall.

마지막으로, 상기 이음과 굴착과정을 토류벽의 설계 심도까지 반복한 후, 건축물이나 도로 등의 구조물이 시공될 공간인 내벽 케이싱(20,30)에 인접하는 지반을 설계 심도까지 굴착하게 되면, 내벽 케이싱(20,30)은 설계 심도까지 노출되면서 원하는 높이의 강재 케이싱을 이용한 토류벽이 완성됨으로써, 본 발명은 시공성과 안전성이 우수한 전면 강재 케이싱 방식의 토류벽 시공방법인 것이다.Finally, after repeating the above seam and excavation process to the design depth of the earth wall, and excavating the ground adjacent to the inner wall casing (20, 30), which is the space in which the building or road structure will be constructed to the design depth, the inner wall casing (20, 30) is the earth wall by using the steel casing of the desired height while being exposed to the design depth, the present invention is an earth wall construction method of the front steel casing method excellent in workability and safety.

추가로, 상기 토류벽인 케이싱 구체(10) 내부를 콘크리트(60)나 골재로 채우는 경우에는 외부 지중 응력에 대한 지지력이 증가하는 효과를 기대할 수 있고, 추후 시공되는 건축물의 기초나 건축물의 일부로도 활용할 수가 있어 케이싱 구체(10)의 철거가 필요하지 않은 장점도 있다.In addition, when filling the interior of the casing sphere 10, which is the earth wall, with concrete 60 or aggregate, the effect of increasing the bearing capacity against external underground stress can be expected, and it can also be used as a foundation or part of the building to be constructed later. There is also an advantage that the removal of the casing sphere 10 is not necessary.

한편, 본 발명인 강재 케이싱 토류벽을 이용한 하천제방 정비공법은 상기 도 3에 도시된 방법을 이용하되, 토류벽이 설치되는 길이방향으로 구간별로 나누어 선단부 케이싱(20,21)을 제작하여 굴착이 이루어져야 하고, 도 4 및 도 5에 도시된 바와 같이, 좌측 제방은 본 발명을 적용하기 위해 절토가 필요한 구간(70)의 일실시예이고 우측 제방은 성토가 필요한 구간(71)의 일실시예인 바, 제방정비를 위한 상기 강재 케이싱 토류벽의 시공방법을 상설하면 다음과 같다.On the other hand, the river bank maintenance method using the steel casing earth wall of the present invention by using the method shown in Figure 3, the excavation is made by dividing the end casing (20, 21) by section in the longitudinal direction in which the earth wall is installed, As shown in Figures 4 and 5, the left bank is an embodiment of the section 70 that needs to be cut in order to apply the present invention, and the right bank is an embodiment of the section 71 that needs to be filled, dike maintenance Permanent construction method of the steel casing earth wall for as follows.

상기 도 3a 내지 도 3d와 같은 강재 케이싱 토류벽 시공을 수행하기 전에 절토가 필요한 제방(73)은 설계 구배로 미리 굴착을 수행해 절토 사면(72)을 형성시킨다(도5a).Before the construction of the steel casing earth wall as shown in Figs. 3a to 3d, the embankment 73, which requires cutting, is excavated in advance by a design gradient to form the cut slope 72 (Fig. 5a).

따라서, 절토가 필요한 제방(73)이 설계 구배로 굴착이 이루어지고 나면, 상기 강재 케이싱 토류벽을 절토 사면(72)에 설계 심도 및 높이까지 설치하는데, 이중 강재 케이싱 토류벽은 시공목적에 부합하게 다수 개를 지상에 노출되는 상단 높이를 달리하면서 계단식으로 시공할 수도 있다. 더불어, 강재 케이싱 토류벽의 시공을 완료한 후 케이싱 구체(10) 외측의 제방 날개부를 절토시켜 하천(74) 단면적을 넓힘으로써 유속을 감소시키면 보다 안락한 느낌의 하천 경관을 조성할 수 있다(도5b).Therefore, after the dike 73 that needs to be cut is excavated with a design gradient, the steel casing earth wall is installed on the cut slope 72 up to the design depth and height, and the double steel casing earth wall corresponds to the construction purpose. Can be cascaded with varying top heights exposed to the ground. In addition, after completing the construction of the steel casing earth wall, by cutting the embankment wing portion outside the casing sphere 10 to expand the river 74 cross-sectional area to reduce the flow rate can create a more comfortable river landscape (Fig. 5b) .

다음으로, 지상에 노출된 케이싱 구체(10)와 절토 사면(72) 사이에 제 1공동구(63)를 형성시키기 위해 케이싱 구체(10)의 상단 레벨을 고려하여 일정 높이로 슬라브 콘크리트(61)를 타설하게 되면, 상기 슬라브 콘트리트(61)는 도로나 인도로 활용할 수 있다(도5c).Next, the slab concrete 61 is fixed at a predetermined height in consideration of the upper level of the casing sphere 10 to form the first cavity 63 between the casing sphere 10 exposed to the ground and the cut slope 72. When poured, the slab concrete 61 can be utilized as roads or sidewalks (FIG. 5C).

또한, 성토가 필요한 구간의 제방(73)에는 도 3의 강재 케이싱 토류벽의 시공방법으로 일정 개수의 강재 케이싱 토류벽을 시공하고(도5b) 토류벽 사이를 케이싱 구체(10) 내부 굴착토를 활용하여 성토한 후 아스콘으로 포장함으로써 도로나 인도로 활용한다(도5c). 여기서도 강재 케이싱 토류벽의 시공 완료 후 케이싱 구체(10) 외측의 제방 날개부를 절토시켜 하천(74) 단면적을 넓힐 수 있다.In addition, in the embankment 73 in the section that needs to be filled, a certain number of steel casing earth walls are constructed by the construction method of the steel casing earth wall of FIG. 3 (FIG. 5B), and the earth is excavated using the excavated soil inside the casing sphere 10 between the earth walls. It is then paved with ascon and used as roads or sidewalks (Figure 5c). Here, after completion of the construction of the steel casing earth wall, the bank blade section outside the casing sphere 10 may be cut to widen the river 74 cross-sectional area.

나아가, 상기 케이싱 구체(10) 내부에 외부 지중 응력에 대한 지지력의 증가를 위해 일정 높이 이하로 콘크리트(60)나 골재로 채움으로써, 케이싱 구체(10) 내부 상부에는 제 2공동구(62)가 형성되는데, 이러한 케이싱 구체(10) 내부의 제 2공동구(62)는 상기 제 1공동구(63)와 함께 전선이나 통신선 또는 각종 관로의 부설 통로로 활용할 수 있고, 특히 상기 제 2공동구(62)의 외벽 케이싱에는 외부 경관의 조망이 가능하도록 창문을 형성시켜 레스토랑이나 미술관과 같은 문화공간을 마련하게 할 수도 있으며, 지상에 노출되는 케이싱 구체(10)의 외면에는 녹화를 함으로써 안락하고 친환경적인 느낌을 가지게 할 수도 있다.Further, by filling the concrete 60 or aggregate to a predetermined height or less to increase the bearing capacity against external underground stresses in the casing sphere 10, a second cavity 62 is formed in the upper portion of the casing sphere 10. The second cavity 62 inside the casing sphere 10 may be utilized as an installation passage of an electric wire or a communication line or various pipes together with the first cavity 63, in particular, an outer wall of the second cavity 22. The casing can also provide windows with a view of the exterior to provide a cultural space such as a restaurant or an art gallery, and the outer surface of the casing sphere 10 exposed to the ground can be greened to provide a comfortable and eco-friendly feel. It may be.

또한, 도로확장 시공을 위해 이러한 강재 케이싱 토류벽을 이용할 수도 있는데, 도 6에 도시된 바와 같은 편도 4차선 도로는 도로공사 표준시방서에 의하면, 도로와 노견에 필요한 폭은 39.8 m이고 기타(비탈면, 소단, 측구, 여유부지) 소요되는 부지의 폭을 최소 약 26.2 m이다.In addition, such a steel casing earth wall may be used for the road extension construction. The one-way four-lane road as shown in FIG. 6 has a 39.8 m width required for roads and roads according to the Road Construction Standard Specification. The minimum width of the site required is 26.2 m.

이러한 기존 도로(78)를 확장하는 경우에 비탈면(75)의 구배와 측구(76) 및 여유부지를 고려하여 도로부지 경계(77)도 이동됨으로써 더 넓은 도로부지를 필요로 하지만, 본 발명은 확장되는 도로 차선수를 고려하여 기존의 도로부지 경계(77)와 비탈면(75) 사이에 도로 양측으로 강재 케이싱 토류벽을 시공함으로써 추가적인 도로부지가 필요하지 않게 된다.When the existing road 78 is expanded, the road site boundary 77 is also moved in consideration of the slope of the slope 75 and the side opening 76 and the spare site, thereby requiring a wider road site. In consideration of the road car is to be constructed by the steel casing earth wall on both sides of the road between the existing road site boundary 77 and the slopes 75, no additional road site is required.

본 발명인 강재 케이싱 토류벽을 이용한 도로확장 시공방법도 상기 도 3에 도시된 방법을 이용하되, 토류벽이 설치되는 길이방향으로 구간별로 나누어 선단부 케이싱(20,21)을 제작하여 굴착이 이루어져야 한다.Road expansion construction method using the steel casing earth wall of the present invention also using the method shown in Figure 3, by dividing the sections by the lengthwise direction in which the earth wall is installed to the front end casing (20, 21) should be made excavation.

더불어, 도 7의 일실시예에서 도시된 바와 같이, 공사 완료 후 토류벽이 지중에 매입될 부분은 지하수 유입 차단과 지중 응력의 지지를 위해 인접하는 구간별 선단부 케이싱(20,21)은 상호 밀착하여 시공되어야 하고, 인접하는 구간별 중간 연결부 내·외벽 케이싱(30,31)도 상호 밀착하여 시공되어야 하지만, 지상에 노출되는 중간 연결부 내·외벽 케이싱(30,31)은 도로위 자동차에서의 경관을 위해 기둥이나 교각 형태로 일정한 간격을 두고 시공되어야 한다.In addition, as shown in the embodiment of Figure 7, the portion of the earth wall is to be embedded in the ground after the completion of the groundwater inflow and the ground end casing (20, 21) adjacent to each other to support the ground stress is in close contact with each other The inner and outer wall casings (30, 31) of the adjacent intermediate sections should be constructed in close contact with each other. However, the inner and outer wall casings (30, 31) of the intermediate connections exposed to the ground provide a view from the vehicle on the road. It should be installed at regular intervals in the form of columns or piers.

강재 케이싱 토류벽을 이용한 도로확장시, 케이싱 이음과 굴착과정을 토류벽의 설계 심도까지 반복한 후, 지상에 노출되는 중간 연결부 내·외벽 케이싱(30,31)은 기둥이나 교각 형태로 일정한 간격을 두고 시공되어야 하므로, 지상에서는 일부 구간에서만 중간 연결부 내·외벽 케이싱(30,31)이 설계 높이까지 반복이음 시공됨으로써, 본 발명에서는 시공성과 안전성이 우수한 전면 강재 케이싱 방식의 토류벽이 시공되는 것이다. 지상에 노출되는 중간 연결부 내·외벽 케이싱(30,31)이 기둥이나 교각 형태로 일정한 간격을 두고 설계 높이까지 시공되는 것은 강재 케이싱 토류벽 상부에 복층 도로의 시공을 예정한 것이므로 단지 도로확장 공사만 수행되는 경우에는 기존의 도로부지 경계(77)와 비탈면(75) 사이 양측의 강재 케이싱 토류벽은 기존 도로(78)의 레벨까지만 설치하면 된다.When expanding the road using steel casing earth wall, repeat the casing fitting and excavation process to the design depth of the earth wall, and then install the inner and outer wall casings (30,31) exposed to the ground at regular intervals in the form of columns or piers. Since it should be, in the ground, the intermediate connection inner and outer wall casings 30 and 31 are repeatedly connected to the design height in some sections, so that the earth wall of the front steel casing system having excellent workability and safety is constructed in the present invention. Since the inner and outer wall casings (30,31) exposed to the ground are constructed in columns or piers at regular heights, the construction of the two-tiered road on the upper part of the steel casing earth wall is planned. In this case, the steel casing earth walls on both sides between the existing road site boundary 77 and the slope 75 need only be installed to the level of the existing road 78.

추가로, 상기 토류벽인 케이싱 구체(10) 내부 굴착 바닥면(50)에는 지하수 유입 차단을 위해 수밀 콘크리트(64)를 타설하고, 케이싱 구체(10) 내부의 일정 높이 이하로는 외부 지중 응력에 대한 지지력의 증가를 위해 조약돌 콘크리트(65)나 골재로 채우는 것이 바람직하다.In addition, in the excavation bottom surface 50 of the casing sphere 10 which is the earth wall, watertight concrete 64 is poured to block groundwater inflow, and the casing sphere 10 has a predetermined height or less for external ground stress. Filling with pebble concrete 65 or aggregate is preferred to increase bearing capacity.

또한, 상기 케이싱 구체(10) 내부의 공동구(66)는 오·폐수관로 등 각종 관로의 통로로 활용할 수 있고, 상기 중간 연결부 외벽 케이싱(31)의 상단은 중간 연결부 내벽 케이싱(30)의 상단보다 일정정도 높게 제작·설치하여 가드레일부(32)로 활용하게 할 수도 있다.In addition, the hollow sphere 66 in the casing sphere 10 can be utilized as a passage of various pipelines, such as a waste water pipe, the upper end of the intermediate connection outer wall casing 31 than the upper end of the intermediate connection inner wall casing (30). It is also possible to make a high degree of manufacturing and installation to utilize as the guard rail portion (32).

나아가 도 8 및 도 9에 도시된 바와 같이, 도로확장을 위한 상기 강재 케이싱 토류벽의 시공방법은 다음과 같다.8 and 9, the construction method of the steel casing earth wall for extending the road is as follows.

먼저, 상기 도 3에 도시된 방법을 이용하여 기존의 도로부지 경계(77)와 비탈면(75) 사이에 양측으로 강재 케이싱 토류벽 시공이 완료(도8a)되면 도로확장을 위해 비탈면(75)과 도로 양측 토류벽 사이를 케이싱 구체(10) 내부 굴착토를 활용하여 성토하고 아스콘으로 기존 도로(78)의 레벨을 고려하여 포장시공함으로써, 기존 도로(78)의 교통을 차단하지 않고도 도로확장 공사를 수행할 수 있다(도8b).First, when the steel casing earth wall construction is completed between the existing road site boundary 77 and the slope 75 by using the method shown in FIG. 3 (FIG. 8A), the slope 75 and the road for the expansion of the road are completed. Through the excavated soil inside the casing sphere 10 between the two earth walls, the land is laid and paved in consideration of the level of the existing road 78 as asphalt, so that the road expansion work can be performed without blocking the traffic of the existing road 78. It can be (Fig. 8b).

다음으로, 강재 케이싱 토류벽 상부에 복층 도로의 시공을 하는 경우에는, 기존의 도로부지 경계(77)와 비탈면(75) 사이에 도로 양측으로 설치된 강재 케이싱 토류벽 시공방법과 동일하게 도로 중앙분리대 부분에도 이중 강재 케이싱(11)을 이용하여 지중과 지상부에 설계 심도 및 높이까지 토류벽을 설치하고 중앙부 이중 강재 케이싱(11) 내부에 수밀 콘크리트(64)와 조약돌 콘크리트(65)를 타설하여야 하며(도9c), 본 발명에 사용되는 강재 케이싱의 강판은 복층도로의 자중과 활하중을 지지할 수 있을 정도의 설계 강성을 가지는 것이어야 한다. 필요에 따라 복층도로 상판(80)을 지지할 수 있을 정도의 충분한 강도를 얻기 위해 중앙부 이중 강재 케이싱(11) 내부에는 철근 콘크리트를 타설할 수도 있다.Next, in the case of constructing a multi-layer road on the upper part of the steel casing earth wall, the same is applied to the middle section of the road in the same way as the steel casing earth wall construction method installed on both sides of the road between the existing road site boundary 77 and the slope 75. Using the steel casing (11) to install the earth wall to the design depth and height in the ground and above the ground, and to place the water-tight concrete (64) and pebble concrete (65) inside the central double steel casing (11), (Fig. 9c), The steel sheet of the steel casing used in the present invention should have a design stiffness sufficient to support the self-load and live load of the double-layer road. If necessary, reinforced concrete may be poured into the central double steel casing 11 in order to obtain sufficient strength to support the upper plate 80.

또한, 상기 기존의 도로부지 경계(77)와 비탈면(75) 사이 양측의 내·외벽 케이싱(20,21,30,31)과 중앙부 이중 강재 케이싱(11)은 구조물의 일부로 활용되므로 케이싱의 철거가 필요하지 않은 장점도 있고, 지상에 노출되는 중간 연결부 내·외벽 케이싱(30,31)의 외면에는 녹화를 함으로써 도로 이용자로 하여금 안락하고 친환경적인 느낌을 가지게 할 수도 있다.In addition, the inner and outer wall casings (20, 21, 30, 31) and the central double steel casing (11) on both sides between the existing road site boundary (77) and slope (75) is utilized as part of the structure, so the removal of the casing There is also an advantage that is not necessary, and by recording the outer surface of the inner and outer casing (30, 31) of the intermediate connecting portion exposed to the ground may make the road users feel comfortable and environmentally friendly.

그 다음으로, 강재 케이싱 토류벽 상부에 복층 도로의 시공을 하는 경우에는 복층도로 상판(80)이 교각 역할을 하는 양측의 중간 연결부 내·외벽 케이싱(30,31)과 중앙부 이중 강재 케이싱(11) 상단에 교좌장치(83)와 함께 거치된다. 여기서, 도로 양측의 중간 연결부 내·외벽 케이싱(30,31)과 중앙부 이중 강재 케이싱(11) 상단이 개방되어 있는 경우에는 당연히 교좌장치(83)가 거치될 수 있도록 강판으로 폐합이음 처리를 해야 하고, 상기 복층도로는 자동차가 다니는 도로에만 한정되는 것은 아니고 기차가 다니는 철로(81)가 부설될 수도 있고, 철로(81) 사이와 갓길 등에는 화단(82)이 설치되어 친환경적인 경관을 조성할 수도 있다(도9d).Next, in the case of constructing a double-layer road on the upper part of the steel casing earth wall, the upper and middle wall joints 30 and 31 on both sides where the double-layer road top plate 80 serves as a pier, and the upper portion of the central double steel casing 11. It is mounted together with the teaching device (83). Here, when the upper and middle wall casings (30, 31) and the central double steel casing (11) of the upper end of both sides of the road is open, of course the closed joints must be treated with a steel plate so that the bridge device (83) can be mounted. In addition, the double-degree road is not limited to the road on which the car is driven, but the railroad tracks 81 may be laid, and flower beds 82 may be installed between the railroad tracks 81 and the shoulders to create an environment-friendly landscape.
