After the installed mortar pressurized packer device is installed in the construction hole, additional longitudinal pressure mortar is installed to create a stable pressurized environment in the grouting area so that the optimal grouting environment and high construction success results can be obtained. It consists of mortar pressurization packer device consisting of entrance, secondary injection pipe, confirmation pipe, cable tie, inner mortar packer, pressurized packer and outer mortar packer and longitudinal pressure mortar, and using mortar which is the basic material of construction site It is characterized by.
본 고안은 쏘일네일링에 공법에 적용되는 가압그라우팅 방법에 관한 것으로 건설토목 현장에서 사용하는 원재료인 몰탈을 이용한 가압그라우팅 주입장치로 시공효율 및 안정성을 크게 높이도록 하는 것이다.
현재 도로와 같은 국가 기반시설이나 도시 건축 및 토목 시설 등의 개발에 있어 국내 지형 특성상 경사지 및 사면 등의 개발이 불가피한 상황이며 이에 따라 개발 후 안전과 쾌적한 환경에 대한 요구가 최우선시 되는 사회적 풍토가 일반화 되어있고 중요한 가치로 부각되어 있는 데에 따라 경제성에 기반을 둔 고효율 시공대책이 필요하게 되었다.
이러한 요구에 따라 경사지 사면 안전 시공법으로 쏘일네일링 지반보강 방법이 전 세계적으로 널리 사용되고 있으며 시공효과 대비 단순한 시공공정은 현장에서의 시공조건을 개선하고 시공기간을 단축시켜줌으로써 타 공법에 비해 경제성 및 다양한 이점을 제공하는 익히 잘 알려져 있는 공법 중 하나가 되었다. 또한 그라우팅을 통한 내부 결집구조는 공사 중이거나 공사 후 지진 및 폭우등과 같은 자연환경의 변화나 기타 외압에 따른 지반의 변화 등에 상당히 큰 대응능력을 갖는 구조적 장점을 가지고 있다는 것이 이미 검증되었다
그러나 기존 소일네일링공법은 천공된 홀 내부를 주 그라우팅 주입재료를 완충하기 위하여 수차례 공정이 반복되어야 하는 어려움이 있음으로 인해 공사기간의 지연 등 다양한 난점들이 발생하게 되고 천공된 홀 내부의 상측으로 향하는 크랙부분에는 주입재가 투입되는데 난점이 있어 지반보강결집력의 저하의 문제를 발생하게 된다.
최근 좀더 조밀한 내부 결집을 얻기 위하여 다양한 방법이 시도되고 있으며 이중 가압그라우팅방법이 주요공법으로 자리매김하고 있으나 가압방식에 따른 추가적인 공사비용의 산정과 가압을 위한 기술적 어려움을 겪고 있는 것이 현실이다. 기존 기술의 경우 가압을 위하여 가압케이싱이나 사출에 의한 특수형태의 가압패커 등과 같은 추가적인 구조물의 삽입을 통해 주입재 가압에 대한 방압을 실현하고 있다. 가압케이싱의 경우 홀 천공 후 고중량의 가압 케이싱을 고도 경사지에서 삽입하여야 하고 가압장치를 이용하여 수동 방압 패킹을 인력으로 진행하여야 하는 어려움 가지고 있을 뿐아니라 시공 시 안전상의 어려움도 내재 되어 있다. 사출에 의한 가압패커는 네일과 밀착성이 떨어져 가압특성이 현저히 저하되는 단점을 가지고 있다.
또 다른 가압그라우팅의 경우 발포우레탄과 같은 화학재료를 사용하고 있어 환경적 문제를 야기할 수 있고 또한 고가의 시공비용 문제를 안고 있는 것이 현실이다.
The present invention relates to a pressurized grouting method applied to the construction method of the soil nailing is to increase the construction efficiency and stability significantly by the pressurized grouting injection device using the mortar which is a raw material used in the construction civil engineering site.
At present, it is inevitable to develop slopes and slopes in the development of national infrastructure such as roads, urban architecture, and civil engineering facilities.Therefore, the social climate where the demand for safety and pleasant environment is the highest priority after development is generalized. As a result, it is expected to have high efficiency construction measures based on economic feasibility.
According to these demands, the soil nailing reinforcement method is widely used worldwide as a slope slope safety construction method, and the simple construction process compared to the construction effect improves the construction conditions in the field and shortens the construction period. It became one of the well-known methods of providing this advantage. In addition, it has already been verified that the internal gathering structure through grouting has a structural advantage that has a great ability to cope with changes in the natural environment such as earthquakes and heavy rains during construction or after construction or other changes in the ground due to external pressure.
However, due to the difficulty of repeating the process several times in order to buffer the main grouting injection material in the existing soil nailing method, various difficulties such as delay in construction period occur and the upper side inside the perforated hole There is a difficulty in the injection of the injection material to the crack portion facing the problem of degradation of the ground reinforcing cohesion.
Recently, various methods have been tried to obtain a more dense internal gathering, and the pressurized grouting method has been established as the main construction method, but it is a reality that it is experiencing technical difficulties for estimating and pressurizing additional construction costs according to the pressurizing method. In the case of the existing technology, the pressure of the injection material is realized by inserting an additional structure such as a pressure casing or a special type of pressure packer by injection. In case of pressurized casing, the high-pressure pressurized casing should be inserted in the altitude slope after hole drilling, and there is a difficulty in carrying out the manual pressure-proof packing by manpower using the pressurizing device. Pressurized packer by injection has a disadvantage in that the pressure characteristics are significantly reduced due to poor adhesion to the nail.
Another pressurized grouting uses a chemical material such as foamed urethane, which may cause environmental problems and also has a high cost of construction.

The present invention is to solve the various difficulties of the prior art by adopting pressure grouting and shortening the construction period and increasing the construction efficiency compared to the prior art by overcoming economic difficulties and realizing structural reinforcement for complete pressurization. The purpose of the present invention is to solve environmental problems by using mortar, which is the main construction material of construction works, as a causative material for pressurization.
본 고안은 상기 기술적 과제를 해결하기 위하여 시공 전에 기 제작된 몰탈가압패커장치를 시공홀에 설치한 후 종단방압몰탈을 추가적으로 시공하여 그라우팅 영역에 안정된 가압환경을 조성함으로서 최적의 그라우팅 시공환경과 양질의 높은 시공 결과를 얻을 수 있도록 하는 것을 그 수단으로 한다. 이는 철근으로 알려진 네일(1), 1차주입관(2), 2차주입관(3), 확인관(4), 케이블타이(5a, 5b, 5c, 5d), 내측몰탈패커(6), 부직포(7), 외측몰탈패커(8), 종단방압몰탈(10)로 구성되며 홀 내부 가압그라우팅에 따른 내압은 1차로 케이블타이(5a, 5b, 5c, 5d), 내측몰탈패커(6), 가압패커(7), 외측몰탈패커(8)로 구성된 몰탈가압패커장치가 담당하며 2차로 종단방압몰탈(10)시공을 통해 2중으로 담당하게 한다.
In order to solve the technical problem, the present invention installs a pre-manufactured mortar pressurization packer in the construction hall and then additionally constructs a longitudinal pressure mortar to create a stable pressurized environment in the grouting area to provide an optimal grouting construction environment and high quality. It is a means to obtain a high construction result. This is known as reinforcing nail (1), primary injection pipe (2), secondary injection pipe (3), confirmation tube (4), cable tie (5a, 5b, 5c, 5d), inner mortar packer (6), nonwoven fabric ( 7), the outer mortar packer (8), longitudinal pressure mortar (10) and the internal pressure according to the pressure grouting inside the hole is the first cable tie (5a, 5b, 5c, 5d), inner mortar packer (6), pressure packer (7), the mortar pressurization packer device composed of the outer mortar packer (8) is in charge of the double through the longitudinal pressure mortar (10) construction.
몰탈을 이용한 가압그라우팅 주입장치는 종래의 소일네일링 공법과 가압그라우팅방식의 소일네일링 공법의 가압을 위한 가압케이싱 및 주가적인 수동방압 패킹이나 사출에 의한 특수형태의 가압패커 등과 같은 추가적인 구조물의 삽입을 제거함으로서 경제성과 시공안전에 대한 우려를 개선하도록 하며 방압특성이 떨어져 발생하는 시공품질 또한 개선할 수 있도록 한다. 또한 가압 원재료를 위해 화학재료를 사용하지 않고 건축토목의 주요 재료인 몰탈을 이용한 가압방식을 채용하고 있으므로 환경적 문제점도 해결할 수 있게 된다.
Pressurized grouting injection device using mortar is used for additional structures such as pressurized casing and pressurized manual packing or special type pressurized packer by injection By eliminating the insert, it is possible to improve the concerns about economics and construction safety, and to improve the construction quality caused by the low pressure discharge characteristics. In addition, it is possible to solve environmental problems since it uses a pressurization method using mortar, which is the main material of construction engineering, without using chemical materials for pressurized raw materials.

도면1, 도면2, 도면3은 본 고안이 이루고자 하는 몰탈을 이용한 가압그라우팅 주입장치를 시공 순서에 따라 설명하기 위한 도면으로 도면1은 천공작업 전 몰탈충진재를 제외한 나머지가 모두 장착된 몰탈가압패커장치를 천공된 시공홀에 넣은 상태를 보인 것이다. 몰탈가압패커장치는 네일(1), 1차주입관(2), 2차주입관(3), 확인관(4), 케이블타이(5a, 5b, 5c, 5d), 내측몰탈패커(6), 부직포(7), 외측몰탈패커(8)로 구성되어 있으며 네일(1), 1차주입관(2), 2차주입관(3), 확인관(4)을 부직포(7)로 감싸고 케이블타이(5a, 5b)로 묶어 부직포 내부공간을 만들되 내부공간에 몰탈을 채워 넣은 후 양생하여 내측몰탈패커(6)를 만들게 된다. 이는 추 후 1차주입관(2)을 통해 몰탈충진재(9)를 주입할 경우 그것이 외부로 유출되지 않도록 고정과 차폐능력을 갖도록 한 것이 목적이다. 다음은 가압패커(7)에 1차주입관(2) 끝이 들어가도록 적당한 간격을 띄운 후 동일한 방법으로 부직포(7)과 케이블타이(5c, 5d)를 이용해 외측몰탈패커(8)를 만들어 양생을 통해 추후 몰탈충진재(9)를 주입할 때의 압력으로부터 충분한 고정능력과 차폐능력을 보장하도록 하는 것이다. 상기 내측몰탈패커(6)와 외측몰탈패커(8) 제작은 동일한 공정에서 이루어진 후 양생에 들어간다.
도면2는 상기 도면1에서 내측몰탈패커(6)와 외측몰탈패커(8)의 양생으로 제작된 몰탈가압패커장치를 천공된 시공홀에 넣은 후 1차주입관(2)을 통해 몰탈충진재(9)를 주입한 상태를 보이고 있으며 이는 외부 자동압력펌프장치를 통해 일정한 압력으로 몰탈충진재(9)를 주입함으로써 시공품질을 높일 수 있도록 할 수도 있다. 몰탈충진재(9) 주입 직후 종단방압몰탈(10)을 천공홀에 시공하고 양생에 동시에 들어감으로서 2차주입관(3)을 통한 최종 그라우팅주입재(11) 가압주입 시 양생된 가압패커(7)은 1차적으로 가압에 대한 내압능력을 가질 것이며 종단방압몰탈(10)은 2차적 내압특성을 갖게 됨으로써 2중으로 가압주입에 대한 안정된 가압주입 환경을 만들게 된다.
도면3은 시공된 전체 외형을 보이는 도면으로 양생된 가압패커(7)과 종단방압몰탈(10)에 기반하여 최종 공정에서 2차주입관(3)을 통해 그라우팅주입재(11)를 주입한 상태를 보이고 있으며 가압패커(7)과 종단방압몰탈(10)은 그라우팅주입재(11)를 주입환경에 충분한 조건을 제공하고 있다. 그라우팅주입재(11)를 주입 시 확인관(4)은 내부 공기, 물, 이물질 배출 통로가 되며 최종적으로 그라우팅주입재(11)가 확인관(4)에서 확인되면 확인관(4) 폐쇄하여 그라우팅 주입 영역의 압력이 증대되도록 하여 시공홀 내의 주변 크랙부분과 공극등에 충분한 그라우팅주입재(11)가 투입 양생되도록 함으로써 시공지점의 지반보강결집특성을 최대로 이끌어 내게 된다.
상기 설명과 같이 몰탈가압패커장치제작 및 내측몰탈패커와 외측몰탈패커 양생 공정이 진행된 후 몰탈충진재 주입 및 종단방압몰탈(10) 시공을 완료한 후 양생하는 공정이 진행되며 최종적으로 그라우팅주입재(11) 주입공정을 완료로 전 공정을 3단계로 단순화 할 수 있게 된다.
