본 발명은 터널공사나 절개지의 경사면공사를 할 때 연약지반의 지지력을 강화시켜 구축되는 구조물의 안정성을 확보하고 지반 내에 흐르는 지하수의 차단과 굴착면의 낙반방지에 의한 굴착면의 안정성을 높이기 위한 직천공 동시 그라우팅 주입장치에 관한 것으로, 더욱 자세하게는 전장 12m 정도 되는 강관으로 제작된 주입장치를 6m 정도로 분할구성하여 운반.보관 시에는 분리하고 그라우팅 작업시에는 조립 연결하여 사용할 수 있게 한 직천공 동시 그라우팅 주입장치에 관한 것이다.The present invention is to secure the stability of the structure to be built by strengthening the bearing capacity of the soft ground during tunnel construction or inclined surface construction of the incision site and to increase the stability of the excavation surface by blocking the groundwater flowing in the ground and preventing the fall of the excavation surface The present invention relates to a simultaneous grouting injection device for drilling. More specifically, the injection device made of steel pipe having a length of about 12 m is divided and transported by about 6 m. It relates to an injection device.

일반적으로 연약지반을 보강하기 위하여 실시되는 지반개량공법은 연약지반에 구멍을 뚫어 그라우팅제나 약액을 강제로 주입하여 응고시키는 공법으로서, SGR공법(Space Grouting Rocket System)이 널리 사용되어 왔다.In general, the ground improvement method performed to reinforce the soft ground is a method of solidifying by injecting a grouting agent or a chemical solution by drilling a hole in the soft ground, and the SGR method (Space Grouting Rocket System) has been widely used.

그러나 상기의 SGR공법은 굴착공에 삽입되는 주입관에 그라우팅제를 순차적으로 충전시킴으로써 작업시간이 많이 소요되어 작업능률이 현저하게 떨어지고 주입관에 삽입된 주입튜브를 순차적으로 인출하면서 그라우팅제를 주입시키므로 각 압출공의 위치에서 주입되는 그라우팅제의 주입량을 확인할 수 없을 뿐만 아니라 주입관의 내부를 분할시키는 구획수단이 충전되는 그라우팅제의 압력에 의해 이탈되어 후퇴하게 되므로 위치마다 그라우팅제의 주입량이 달라 그라우팅이 균일하게 실시되지 않는 문제점이 있었다.However, the above-mentioned SGR method takes a lot of work time by sequentially filling grouting agent into the injection tube inserted into the excavation hole, so the work efficiency is remarkably decreased, and the grouting agent is injected while drawing out the injection tube inserted into the injection tube sequentially. Not only the injection amount of the grouting agent injected at each extruded hole can be confirmed, but also the partitioning means for dividing the inside of the injection tube is separated by the pressure of the grouting agent filled, so the grouting agent is injected in different positions. There was a problem that this was not performed uniformly.

이러한 문제점을 해소하기 위하여, 국내특허등록 제10-468113호 "강관 동시 주입 그라우팅 장치"(이하 종래기술 1이라 함)와, 국내특허등록 제10-570732호 "강관 보강용 다단 동시 그라우팅 주입장치"(이하 종래기술 2라 함)가 제안되어 있다.In order to solve this problem, Korean Patent Registration No. 10-468113 "steel pipe simultaneous injection grouting device" (hereinafter referred to as the prior art 1), and Korean Patent Registration No. 10-570732 "multi-stage simultaneous grouting injection device for steel pipe reinforcement" (Hereinafter referred to as prior art 2) has been proposed.

상기 종래기술 1은 선단이 밀폐형으로 되고 외주에 압출공이 천공된 제1파이프의 후단에 구획수단을 개입시키면서 외주에 압출공이 천공되고 일정 길이의 파이프를 연속적으로 연결하고 이들 파이프에 주입튜브를 순차적으로 연결설치하며 후단 파이프의 단부에서 각 주입튜브에 그라우팅을 공급시켜 각 파이프에 주입시키도록 하는 구성되어 있음을 알 수 있다.In the prior art 1, the tip is closed and the extrusion hole is perforated on the outer circumference while the extruded hole is perforated on the rear end of the first pipe, and the pipes of a predetermined length are continuously connected and the injection tubes are sequentially connected to the pipes. It can be seen that the connection is installed to supply grouting to each injection tube at the end of the downstream pipe and to be injected into each pipe.

그러나, 상기의 종래기술 1은 파이프를 다단으로 연결시킬 때마다 별도의 주입튜브를 증가시키면서 연결시켜야하므로 작업성이 크게 떨어지는 문제점이 있고, 일정한 길이로 되어있는 파이프의 개수가 너무 많아 전체적인 구성이 약화되고 각 파이프 사이에 개입되어 있는 구획수단의 설치구조상 구획수단의 지지력이 약하게 되어 있어서 고압으로 충전되는 그라우팅제의 압력에 의해 이탈될 수 있으며 이탈될 경우에는 파이프를 분리시키는 의미가 없어지고 위치마다 그라우팅제의 량이 다르게 충전되어 그라우팅 작업이 균일하게 시행되지 않는 문제점이 있었다.However, the prior art 1 has a problem in that workability is greatly reduced because it is required to connect a separate injection tube every time the pipe is connected in multiple stages, the number of pipes having a constant length is too weak overall structure And the bearing capacity of the partition means is weak due to the installation structure of the partition means intervening between the pipes, so it can be separated by the pressure of the grouting agent filled with high pressure. There is a problem that the grouting operation is not uniformly performed because the amount of the agent is filled differently.

상기 종래기술 2는 상기 종래기술 1의 문제점을 개선하기 위하여 안출된 것이나 이는 그라우팅 강관이 분할되지않고 한 덩어리로 구성되어 있기 때문에 다음과 같은 문제점이 내포되어 있다.The prior art 2 has been devised to improve the problems of the prior art 1, but since the grouting steel pipe is composed of a single mass without being divided, the following problems are included.

즉, 연약지반으로 인하여 그라우팅공법을 시행할 필요가 있는 곳에서는 그라우팅 시공을 하기 위하여 우선 지반천공을 하고 이 구멍에 그라우팅 강관을 삽입하여 그라우팅제를 주입하게 되는데 이때 지반에 천공된 구멍이 12m 정도 되므로 강 관도 12m 정도의 길이로 제작되는 것이 일반적이다.That is, where the grouting method needs to be performed due to soft ground, ground drilling is performed first for grouting construction and grouting agent is injected by inserting grouting steel pipe into this hole. Steel pipes are also generally manufactured to a length of about 12m.

그러나, 강관이 12m 정도 되면 이를 제작하기에 불편한 점이 많고 운반 및 보관 등 취급에 있어 많은 어려움이 뒤따르게 되며 공사현장의 진입로, 작업현장의 입지나 주변여건이 열악한 경우가 대부분인 지반 굴착과 같은 토목공사의 경우에 있어서는 이들의 운반이나 설치작업에 상당한 애로를 겪게 되고 이로 인하여 많은 노고와 인력의 투입은 물론 공기가 길어지는 등의 문제점이 있었다However, when the steel pipe is about 12m long, it is inconvenient to manufacture it, and there are many difficulties in handling such as transportation and storage, and civil works such as ground excavation, which are mostly inaccessible to the construction site, the location of the work site, and the surrounding conditions are poor. In case of this, they suffered considerable difficulties in their transportation or installation work, which caused a lot of labor and manpower, as well as a long air.

본 발명은 상기한 바와 같은 종래의 문제점을 해결하기 위하여, 그라우팅 장치를 두개의 조립체로 분할하고 분할된 양쪽 조립체를 조립 또는 해체가 용이하도록 하여 운반이나 보관 등의 취급을 편리하게 하고 지반 굴착과 같은 공사현장에서도 주변의 열악한 여건에도 쉽게 사용할 수 있게 한 직천공 동시 그라우팅 주입장치를 제공함에 그 목적이 있다.In order to solve the conventional problems as described above, the grouting device is divided into two assemblies, and both divided assemblies can be easily assembled or disassembled to facilitate handling, transportation, and the like. The purpose is to provide a direct perforation simultaneous grouting injection device that can be easily used even in the harsh conditions of the construction site.

상기와 같은 목적을 달성하기 위한 본 발명은, 선단이 폐쇄되고 후단이 개구된 제1강관의 내부공간을 구획수단으로 제1주입실과 제2주입실로 구획하며 상기 제1,2주입실에 각각 제1,2주입연장관의 선단이 위치하도록 주입관 홀더로 설치한 다음 제1강관의 후단에 연결수단을 나사 결합하여 된 제1조립체;와 The present invention for achieving the above object, the front end is closed and the rear end is divided into the first injection chamber and the second injection chamber by the partition means of the inner space of the first steel pipe and the first and second injection chamber respectively A first assembly installed by an injection tube holder so that the tip of the 1,2 injection tube is positioned and then screwing the connecting means to the rear end of the first steel pipe; and
