Description

지하 구조물의 보수 보강 공법{Maintenace and Reinforce Engineering Method of Structure Under Ground}Maintenance and Reinforce Engineering Method of Structure Under Ground

본 발명은 지하 구조물의 보수 보강 공법에 관한 것으로, 특히 관거, 암거, 공동구 등의 지하 구조물을 굴착하지 않고 보수 보강하는 공법에 관한 것이다.The present invention relates to a repair reinforcement method for underground structures, and more particularly to a method for repairing reinforcement without digging underground structures such as conduits, culverts, cavities.

주지하는 바와 같이 관거, 암거, 공동구 등과 같은 지하 구조물에 이상이 발견되거나 노후되면 상기 지하 구조물이 매설된 지역을 굴착한 후, 상기 지하 구조물을 철거한 후 신설하거나 노후부분을 콘크리트 보수재나 금속패널 도는 섬유계 보수재를 부착하는 방법으로 보수 보강한다.As is well known, when an abnormality is found or aged in underground structures such as conduits, culverts, and joint holes, the area where the underground structures are buried is excavated, and after the underground structures are demolished, new construction or renovation of old parts is carried out. Repair reinforcement by attaching fiber repair materials.

그러나 이러한 기존 구조물 개량공법은 지면을 굴착하여야 하기 때문에 사람과 차량의 교통을 방해하여 불편을 주고, 지하 매설물(각종 케이블, 상, 하수도 등)의 철거나 이설이 불가피하여 공사기간과 비용이 과다하게 소요되며, 지반침하에 의한 주변 건축물의 부등침하가 우려되는 등의 문제가 있다.However, this existing structure improvement method requires the excavation of the ground, which disturbs traffic between people and vehicles, and inconveniently removes or relocates underground works (various cables, water, sewage, etc.), resulting in excessive construction period and cost. There is a problem such as concern about the unequal settlement of the surrounding buildings due to ground subsidence.

또한, 부분 보수 보강의 경우 콘크리트 보수재는 자재비가 고가이며 기존 구조물과의 부착력 부족으로 조기탈락 및 부식의 우려가 있고, 금속패널 및 섬유계 보수재는 시공이 어려우며 기존 구조물과 탄성계수의 차이로 부착력이 떨어져 조기 탈락하게 되는 등의 문제가 있다.In addition, in the case of partial repair reinforcement, concrete repair materials are expensive and there is a risk of premature dropout and corrosion due to lack of adhesion to existing structures, and metal panels and fiber-based repair materials are difficult to install, and adhesion strength is different due to the difference in elastic modulus from existing structures. There is a problem such as falling off early.

본 발명은 상기와 같은 종래의 문제를 감안하여 지면을 굴착하거나 구조물을 철거하지 않고 지하 구조물을 건식상태에서 보수 보강하며 보수 보강되는 신설 콘크리트와 기존 구조물의 부착력이 향상되도록 함으로써, 공사기간과 비용의 절감은 물론 교통피해나 주변 건물의 부등침하에 대한 우려를 제거하고, 지하 구조물의 내구연한을 증가시키는 지하 구조물의 보수 보강 공법을 제공함에 그 목적이 있다.The present invention in view of the conventional problems as described above to improve the adhesion of the new concrete and the existing structure to be repaired and reinforcement of the underground structure in a dry state without digging the ground or demolishing the structure to improve the construction period and cost of The purpose of the reduction is to provide a repair and reinforcement method for underground structures that eliminates concerns about traffic damage or unequal settlement of surrounding buildings and increases the durability of underground structures.

이러한 목적을 달성하기 위한 본 발명은 지하 구조물의 내벽에 콘크리트를 타설하여 보수 보강하는 공지의 것에 있어서, 지하 구조물의 내부에 가물막이 수밀재와가배수관을 설치하고, 건식상태에서 철근이 배설된 지하 구조물과 패널 사이로 지상에서 구조물까지 구멍을 뚫고 이러한 구멍을 통하여 콘크리트를 타설 또는 그라우팅하는 지하 구조물의 보수 보강 공법을 제안한다.In order to achieve the above object, the present invention provides a well-known method of reinforcing and repairing concrete by placing concrete on the inner wall of an underground structure. We propose a repair and reinforcement method for underground structures that drill a hole from the ground to the structure between the structure and the panel and pour or grout concrete through these holes.

이에 따라 본 발명은 지면을 굴착하거나 철거하지 않고 저렴한 비용으로 지하 구조물을 신속하게 보수 보강할 수 있고, 보수 보강된 지하 구조물의 내구연한이 증대된다.Accordingly, the present invention can quickly repair and reinforce the underground structure at low cost without digging or removing the ground, and the durability of the repaired and reinforced underground structure is increased.

상기와 같은 본 발명의 구성 및 작용을 첨부한 도면에 의거 상세히 설명하면 다음과 같다.Referring to the configuration and operation of the present invention as described above in detail as follows.

도 1은 본 발명에 의한 비굴착 건식 보수 보강 공법의 공정도이고, 도 2는 지하 구조물 내부에 물돌리기 수단이 설치된 상태를 도시한 설명도이며, 도 3은 본 발명에 의하여 건식 보수 보강하는 상태를 도시한 설명도이다.1 is a process diagram of a non-excavation dry repair reinforcement method according to the present invention, Figure 2 is an explanatory view showing a state in which the water turning means is installed in the underground structure, Figure 3 is a dry repair reinforcement state according to the present invention It is explanatory drawing shown.

본 발명은 지하 구조물(10)의 내부에 가물막이 수밀재(16)와 가배수관(20)을 설치하는 공정과, 지상에서 지하 구조물(10)의 내부로 관통되는 통공(13)을 형성하는 공정과, 지하 구조물(10)의 보수 보강 면(11)에 건식상태에서 철근(14)을 배설하고 바닥면(12)에 콘크리트를 타설 양생하는 공정과, 지하 구조물(10)에 앵커볼트(22)를 설치하고 이러한 앵커볼트(22)에 패널(15)이 고정되도록 설치하며 상기 패널(15)과 지하 구조물(10) 사이에 콘크리트를 타설 또는 그라우팅하는 공정과, 패널(15)을 제거하고 가물막이 수밀재(16)와 가배수관(20)을 철거하는 공정으로 지하 구조물이 보수 보강하는 것이다.The present invention provides a process for installing the temporary watertight material 16 and the water drainage pipe 20 in the interior of the underground structure 10, and forming a through hole 13 penetrating into the interior of the underground structure 10 from the ground. And, the process of laying the reinforcing bar 14 in the dry state on the repair reinforcement surface 11 of the underground structure 10 and pouring concrete on the bottom surface 12, and anchor bolts 22 to the underground structure (10) And installing the panel 15 to be fixed to the anchor bolt 22 and placing or grouting concrete between the panel 15 and the underground structure 10, removing the panel 15, and closing the temporary curtain. The underground structure is to be repaired and reinforced by the process of demolishing the watertight material 16 and the drainage pipe 20.

즉, 보수 보강하고자 하는 지하 구조물(10)의 시점부와 종점부에 지지구(19)와 수밀튜브(17) 및 수밀패널(18)로 되는 가물막이 수밀재(16)를 설치하고, 상기 시점부와 종점부의 수밀재(16)를 연결하는 가배수관(20)과 상기 가배수관(20)을 지지하는 받침대(21)를 설치하여 보수 보강될 구간을 차단하여 건식상태가 되도록 한다.That is, a temporary film watertight member 16 including the support 19, the watertight tube 17, and the watertight panel 18 is installed at the starting point and the end point of the underground structure 10 to be repaired and reinforced. And a drainage pipe 20 connecting the watertight member 16 of the end portion and a pedestal 21 supporting the drainage pipe 20 to block a section to be repaired and reinforced.

이어서 상기와 같은 건식상태에서 지하 구조물(10)의 보수 보강될 면(11)과 바닥면(12)을 정리하고, 지상에서 지하 구조물(10)의 내부로 관통되는 통공(13)을 형성하며, 아울러 보수 보강 면(11)에 철근(14)을 배설하고 바닥면(12)에 콘크리트를 타설하여 양생시킨다.Subsequently, in the dry state as described above, the surface 11 and the bottom surface 12 to be repaired and reinforced of the underground structure 10 are arranged, and a through hole 13 penetrating into the interior of the underground structure 10 is formed on the ground. In addition, the reinforcement 14 is disposed on the reinforcement reinforcement surface 11 and concrete is poured on the bottom surface 12 to cure.

이어서 철근(14)이 배설된 보수 보강 면(11)에 패널(15)을 설치하고, 앵커볼트(22)를 이용하여 패널(15)이 지하 구조물(10)에 고정 지지되도록 한 후, 지상에서 통공(13)을 통하여 지하 구조물(10)과 패널(15) 사이로 콘크리트를 타설 또는 그라우팅하여 양생시킨다.Subsequently, the panel 15 is installed on the repair reinforcement surface 11 on which the reinforcing bar 14 is disposed, and the panel 15 is fixed to the underground structure 10 using the anchor bolt 22 to be fixed on the ground. Through the hole 13, the concrete is poured between the underground structure 10 and the panel 15 to pour or grout to cure.

이어서 패널(15)을 철거하고 돌출된 앵커볼트(22)를 제거하며, 통공(13)을 메우고 가물막이 수밀재(16)와 가배수관(20) 및 받침대(21)를 철거한다.Subsequently, the panel 15 is removed and the protruding anchor bolts 22 are removed, the through holes 13 are filled, and the temporary barrier watertight member 16, the drainage pipe 20, and the pedestal 21 are removed.

이와 같이 보수 보강된 신설 콘크리트는 내부에 철근(14)이 배설됨과 아울러 지하 구조물(10)과 신설 콘크리트가 앵커볼트(22)에 의하여 일체화 된 상태이므로, 단면이 매우 조밀하고 기존 구조물(10)과 부착력이 매우 우수하여 지하 구조물의 내구연한이 증대되며, 이러한 지하 구조물(10)의 보수 보강 효과를 더욱 우수하게 하기 위하여 패널(15)을 철거하지 않고 내벽으로 사용할 수 있다.The new concrete reinforced with reinforcement as described above is provided with reinforcing bars 14 and the underground structure 10 and the new concrete are integrated by the anchor bolt 22, so that the cross section is very dense and the existing structure 10 and Since the adhesion is very excellent, the durability of the underground structure is increased, and the panel 15 may be used as an inner wall without demolishing to further improve the repair reinforcement effect of the underground structure 10.

또한, 지하 구조물(10)로 흐르는 물의 양이 적은 경우에는 상기 지하 구조물(10)을 보수 보강할 때 가배수관(20)을 별도로 설치하지 않고 패널(15)이 가배수관(20)의역할도 함께 하도록 하여 보수 보강에 소요되는 비용과 공수를 절감시킬 수 있다.In addition, when the amount of water flowing to the underground structure 10 is small, the panel 15 serves as the drainage pipe 20 without separately installing the drainage pipe 20 when repairing and reinforcing the underground structure 10. By doing so, the cost and labor of reinforcement can be reduced.

상기와 같이 본 발명은 지하 구조물의 내부에 가물막이 수밀재와 가배수관을 설치하고, 건식상태에서 철근이 배설된 지하 구조물과 패널 사이로 지상에서 콘크리트를 타설 또는 그라우팅하여 보수 보강하는 것으로, 지면을 굴착하거나 구조물을 철거하지 않고 지하 구조물을 보수 보강할 수 있어 교통을 방해하지 않으며, 저렴한 비용으로 신속하게 보수 보강 할 수 있고, 지반침하로 인한 주변 검축물의 부등침하에 대한 우려가 없으며, 아울러 보수 보강되는 신설 콘크리트와 기존 구조물의 부착력이 우수하여 지하 구조물의 내구연한을 증가되는 등의 유용한 효과가 있다.As described above, the present invention is to install a temporary watertight member and a water drainage pipe in the interior of the underground structure, and to reinforce and repair the concrete by placing or grouting the ground from the ground between the underground structure and the panel where the rebar is disposed in the dry state. It is possible to repair and reinforce the underground structure without dismantling the structure, so that it does not interfere with the traffic, can be repaired and reinforced quickly and at low cost, and there is no concern about the sedimentation of surrounding specimens due to ground subsidence. Excellent adhesion of the new concrete and the existing structure has a useful effect such as increasing the durability of the underground structure.
