본 발명은 절토작업으로 새로이 조성되는 비탈면에 간편하고 신속하게 비탈면 보호구조물을 시공할 수 있도록 하여주는 비탈면 보호구조물의 시공방법에 관한 것이다.The present invention relates to a construction method of a slope protection structure that allows the construction of a slope protection structure simply and quickly on the newly formed slope surface by cutting work.
산간지역등지에 개설되는 도로공사에는 도로의 양측부에 산지가 절토되어 새로이 조성되는 비탈면이 많아지게 되고, 이러한 절토비탈면은 그 지표면이 불안정하기때문에 비탈면보호공사를 별도로 수행하여 주지 아니하면, 비탈면에서 부수러지는 돌덩어리들이 아래로 낙하되어 도로의 통행자들에게 불편을 초래하는 경우가 빈번히 발생한다.In road constructions that are established in mountainous areas, the hills are cut on both sides of the road, and newly formed slopes are increased. These cut slopes are unstable, so unless the slope protection work is performed separately, Frequently, crushing stone blocks fall down, causing inconvenience to pedestrians on the road.
이와같은 경우에 시행되는 전통적인 비탈면 보호구조물은 축대, 콘크리트 옹벽 및 지압판을 이용하여 옹벽을 시공하였던 것이나, 축대와 콘크리트 옹벽은 공사기간이 길어지고 공사비용이 많이 소요되는 결함이 있었다.The traditional slope protection structure used in this case was the construction of retaining walls using a shaft, concrete retaining wall and acupressure plate, but the retaining wall and concrete retaining wall had a long construction period and a high cost of construction.
이러한 경우에 비교적 저렴한 비용으로 비탈면 보호구조물이 시공되도록 하여주는 방법으로서, 지압판을 이용한 옹벽의 시공방법은 제1도에 도시되는 바와같이, A 절토된 비탈면(1)에 소정의 위치마다 앵커구멍(2)들을 굴착한 후에, 그 앵커 구멍(2)들의 내부에 앵커볼트(3)들을 삽입하여 양생시키는 앵커볼트 매립공정 ; B. 상기 앵커볼트(3)들의 선단부에 형성되는 나사부(31)에, 중앙에 뚫려져 있는 체결구멍(51)을 통하여 지압판(5)을 끼운후에, 체결구멍(51)의 체결턱부내에서 체결너트(4)로서 체결하여 고정시키는 지압판 체결공정 ; C. 상기 지압판(5)과 절토비탈면(1)사이의 틈새에는 토사를 채워넣어 다지는 토사채움공정 ; 들을 하부에서부터 상부로 순차적으로 시행함으로써, 전체 지압판 옹벽을 축조하는 공법이다.In this case, as a method for constructing the slope protection structure at a relatively low cost, the method of constructing the retaining wall using the pressure plate is as shown in Figure 1, the anchor hole at a predetermined position in the cut slope (A) as shown in FIG. 2) after the excavation, anchor bolt embedding step of curing by inserting the anchor bolt (3) in the interior of the anchor holes (2); B. After inserting the pressure plate 5 through the fastening hole 51 drilled in the center of the screw portion 31 formed at the front end portion of the anchor bolts 3, the fastening hole is fastened in the fastening jaw portion of the fastening hole 51. Acupressure plate fastening step of fastening by fixing as a nut (4); C. Soil filling step of filling the soil in the gap between the pressure plate (5) and the cut slope (1); It is a method of constructing the entire pressure plate retaining wall by sequentially performing them from the bottom to the top.
이러한 종래의 지압판옹벽은 지압판(5)마다 그 내부주면의 토사를 독자적으로 지지하여 주는 구조로 시공되기 때문에, 지압판의 4변들을 하나하나 일치시키면서 시공되어야 하였으며, 또한 각 지압판마다 앵커볼트를 고정시켜야 되므로 이로 인하여 시공이 번거로워지고, 공사기간이 길게 소요되는 결함이 있었다.Since the conventional acupressure plate retaining wall is constructed in a structure that independently supports the soil of the inner circumferential surface of each acupressure plate 5, it has to be constructed while matching the four sides of the acupressure plate one by one, and anchor bolts must be fixed for each acupressure plate. Because of this, construction is cumbersome, and there was a defect that requires a long construction period.
본 발명의 목적은 상기 지압판옹벽보다 더욱 간편하고 신속하게 비탈면 보호구조물을 시공할 수 있도록 하여주는 비탈면 보호구조물의 시공방법을 제공하는 데에 있다.An object of the present invention is to provide a construction method of the slope protection structure that allows the construction of the slope protection structure more easily and quickly than the pressure plate retaining wall.
이하, 첨부도면에 따라서 본 발명의 기술적구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail as follows.
본 발명은, 절토된 비탈면(10)의 전방에 옹벽을 형성하기 위하여 콘크리트관 또는 철관(20)을 설치하는 장소에 터파기를 한 뒤 콘크리트가 타설하는 기초작업공정과 ; 다수개의 콘크리트관 또는 철관(20)을 콘크리트가 타설된 기초부(11)에 세워서 상호 밀착되게 하는 동시에 각 콘크리트관 또는 철관(20)의 하부는 다시 콘크리트타설하여 고정부(12)에 의하여 하단부를 고정하며, 상부는 콘크리트관 또는 철관(20)상호간을 고정볼트(30)로 연결하여 일체화 하는 콘크리트관 또는 철관설치공정과 ; 상기 공정으로 비탈면(10)의 전방에 배치된 콘크리트관 또는 철관(20)들을 비탈면의 지중에 앵커볼트(40)로 고정하는 콘크리트관 또는 철관고정공정과 ; 콘크리트관 또는 철관고정공정 후 절토면과 콘크리트관 또는 철관사이에 토사를 채우는 공정과 ; 상기 공정을 반복하여 상부로 옹벽을 시공하므로써 비탈면 보호구조물을 비탈면에 구축시킴에 기술적 구성상의 특징이 있다.The present invention, the foundation work process for pouring concrete after the excavation in the place to install the concrete pipe or steel pipe 20 to form the retaining wall in front of the cut slope 10; A plurality of concrete pipes or steel pipes 20 are placed on the foundation portion 11 on which concrete is poured to be in close contact with each other, and at the same time, the lower part of each concrete pipe or steel pipe 20 is concrete-cast again to fix the lower portion by the fixing part 12. A concrete pipe or steel pipe installation process of fixing and connecting the concrete pipe or steel pipe 20 to each other by fixing bolts 30 to be integrated; A concrete pipe or steel pipe fixing step of fixing concrete pipes or iron pipes 20 disposed in front of the slopes 10 with anchor bolts 40 in the slope of the slope; Filling the soil between the cut surface and the concrete or steel pipe after fixing the concrete or steel pipe; By repeating the above steps to construct the retaining wall to the upper side there is a technical configuration feature to build the slope protection structure on the slope.
상기 콘크리트관 또는 철관(20)은 직경 0.7-1m, 길이 4-6m의 것을 사용한다.The concrete pipe or iron pipe 20 uses a diameter of 0.7-1m, 4-6m in length.
상기 각 콘크리트관 또는 철관(20)은 상호 연결되게 상부에 연결구멍(21)을 형성하고, 앵커볼트(40)와 연결되게 앵커구멍(22)을 각각 형성한다.Each concrete pipe or steel pipe 20 is connected to each other to form a connection hole 21 in the upper portion, and the anchor bolt 40 is formed to form an anchor hole 22, respectively.
따라서 비탈면의 높이에 따라서 콘크리트관 또는 철관(20)의 계단식 설치높이가 설정되는 것으로, 옹벽시공시 옹벽용으로 비탈면의 전방에 터파기를 하여 콘크리트타설공사를 하여 양생시키고, 다수개의 콘크리트관 또는 철관(20)을 횡렬로 배치하되 상호 밀착되게 배치하여 하단부가 지중에 매설되게 콘크리트타설하여 고정하고, 각 콘크리트관 또는 철관(20)의 상부에 형성된 연결구멍(21)으로 고정볼트(30)로 연결하여 상호 일체화되게 한다.Therefore, the stepped installation height of the concrete pipe or the steel pipe 20 is set according to the height of the slope, and when the retaining wall is constructed, it is made by smashing the concrete in front of the slope for curing of the retaining wall, and curing the concrete. 20) arranged in a horizontal row, and placed in close contact with each other by placing concrete at the lower end to be embedded in the ground, and connected by fixing bolts 30 with connection holes 21 formed in the upper portion of each concrete pipe or steel pipe 20 Integrate with each other.
이때, 고정볼트(30)의 양끝단은 양끝단에 각각 배치된 콘크리트관 또는 철관(20)의 내주면에 고정되게 하여 좌,우로 계속적으로 콘크리트관 또는 철관(20)이 배치될때 상호 이격되지 않도록 하므로써 토사의 유출을 방지하도록 한다.At this time, both ends of the fixing bolt 30 is fixed to the inner circumferential surface of the concrete pipe or steel pipe 20 disposed at both ends so as not to be spaced apart from each other when the concrete pipe or steel pipe 20 is continuously arranged to the left and right. Prevent the soil from leaking out.
콘크리트관 또는 철관(20)의 배치후 콘크리트관 또는 철관(20)의 상단에 형성된 앵커구멍(21)으로 지중에 매설된 앵커볼트(40)를 빼내어 고정한다.After the arrangement of the concrete pipe or steel pipe 20, the anchor bolts (21) buried in the ground by anchor holes 21 formed in the upper end of the concrete pipe or steel pipe 20 is fixed.
그후 콘크리트관 또는 철관(20)들의 배면에 토사를 채워서 다져지게 하며, 이때 토사의 높이는 콘크리트관 또는 철관의 상부보다 약간 낮은 높이까지 채우도록 한다.Thereafter, the soil is filled in the back of the concrete pipe or iron pipes 20 to be compacted, and the height of the soil is filled to a height slightly lower than the upper portion of the concrete pipe or steel pipe.
상기 1차 옹벽의 시공 후 다단계의 옹벽의 시공시 채워진 토사에 상술한 방법으로 옹벽공사를 반복하면 되는 것이다.What is necessary is to repeat the retaining wall construction by the above-described method on the earth and sand filled during the construction of the multi-step retaining wall after the construction of the primary retaining wall.
한편, 비탈면이 급경사로 이루어진 경우 상술한 방법으로 콘크리트관 또는 철관(20)을 계단식으로 시공할 수 없으므로 이때에는 콘크리트관 또는 철관(20)의 높이를 높힐 수 밖에 없다. 따라서 이때에는 이미 시공된 콘크리트관 또는 철관(20)내에 토사를 채우되 상단부보다 낮게 채워서 콘크리트관 또는 철관(20)의 상단 부는 빈공간으로 남겨 놓은 뒤 새로운 콘크리트관 또는 철관(20)을 상기 시공된 콘크리트관 또는 철관(20)과 일직선상으로 맞추어서 세운다.On the other hand, if the slope is made of steep slopes, the concrete pipe or iron pipe 20 can not be constructed in a stepwise manner as described above, at this time, the height of the concrete pipe or steel pipe 20 is bound to increase. Therefore, at this time, the earth or sand filled in the concrete pipe or steel pipe 20, but lower than the upper end of the concrete pipe or steel pipe 20 to leave the upper portion of the concrete pipe or steel pipe 20 empty space after the new concrete pipe or steel pipe 20 Set up in line with the concrete pipe or steel pipe (20).
그 후 새로운 콘크리트관 또는 철관(20)을 통해 상부에서 콘크리트 모르타르를 부어 하부의 콘크리트관 또는 철관(20)의 상단부와 새로운 콘크리트관 또는 철관(20)의 하단부의 내부에 콘크리트 모르타르(15)가 채워져서 양생되게 하므로서 상,하부의 콘크리트관 또는 철관(20)을 연결시켜 콘크리트관 또는 철관(20)의 높이를 높힐 수가 있는 것이다.Thereafter, the concrete mortar is poured from the upper portion through the new concrete tube or the iron tube 20, and the concrete mortar 15 is filled in the upper portion of the lower concrete tube or the iron tube 20 and the lower portion of the new concrete tube or the iron tube 20. By lowering the curing to connect the upper and lower concrete pipes or iron pipes 20 is to increase the height of the concrete pipes or steel pipes (20).
그리고 콘크리트관 또는 철관(20)을 제2도 내지 제6도와 같이 원형관에 대해서만 설명하였으나, 제7도의 (a)(b)(c)와 같이 단면상 사각형관, 직사각형관, 육각형관등으로 시공하여도 무방하며, 그 이외에 어떠한 형상이나 재질의 것을 사용하여도 무방하다.The concrete pipe or the steel pipe 20 is described only with respect to the circular pipe as shown in FIGS. 2 to 6, but it is constructed as a rectangular pipe, a rectangular pipe, a hexagonal pipe, etc. in cross section as shown in (a) (b) (c) of FIG. It is also possible to use any other shape or material.
이와같이 본 발명의 옹벽시공공사는 콘크리트 콘크리트관 또는 철관을 이용하여 시공하므로서 시공작업이 매우 간편하고 신속하게 비탈면 보호구조물을 시공할 수가 있는 것이다.In this way, the retaining wall construction of the present invention can be constructed by using a concrete concrete pipe or steel pipe is very easy and quick to be able to construct a slope protection structure.
