Description

연약지반 개량장비용 케이싱{Casing for equipment improvement of soft ground}Casing for equipment improvement of soft ground

본 발명은 연약지반 개량장비용 케이싱에 관한 것으로, 더욱 상세하게는 케이싱의 내부로 유입되는 이토를 방지하여 시공품질을 향상시킬 수 있음은 물론 연약지반의 다짐공정을 실행할 수 있으므로 시공효율을 극대화시킬 수 있는 연약지반 개량장비용 케이싱에 관한 것이다.The present invention relates to a casing for soft ground improvement equipment, and more particularly, it is possible to improve the construction quality by preventing the soil coming into the inside of the casing, as well as to maximize the construction efficiency because the compact ground can be executed. It relates to a casing for soft ground improvement equipment that can be.

일반적으로 연약지반 개량장비용 케이싱(1)은 도 1에 도시된 바와 같이 연약지반 개량장비의 리더에 승하강할 수 있도록 설치되는 케이싱 파이프(10)와, 상기 케이싱 파이프(10)의 하부에 형성되는 슈(20)로 구성된다.In general, the casing (1) for soft ground improvement equipment is formed on the casing pipe (10) and the lower portion of the casing pipe (10) which is installed to be lowered to the leader of the soft ground improvement equipment, as shown in FIG. The shoe 20 is comprised.

따라서 상기 케이싱 파이프(10)가 지중으로 관입 및 인발을 반복하면서 보강부재(모래 등) 파일을 시공하여 연약지반을 개량하게 되는데, 이때 상기 슈(20)는 상기 케이싱 파이프(10)가 지중으로 관입할 경우에는 밀폐되고, 반대로 상기 케이싱 파이프(10)가 인발할 경우에는 자중에 의해서 양측으로 개방되면서 내부에 투입 된 보강부재를 배출시키는 기능을 수행하게 된다.Therefore, the casing pipe 10 improves the soft ground by constructing a reinforcing member (sand, etc.) pile while repeating penetration and drawing into the ground, wherein the shoe 20 penetrates the casing pipe 10 into the ground. If the case is sealed, on the contrary, when the casing pipe 10 is drawn out, the casing pipe 10 is opened to both sides by its own weight to discharge the reinforcing member introduced therein.

그러나, 종래의 슈(20)는 단순히 개폐동작을 반복할 뿐 상기 케이싱 파이프(10)를 긴밀하게 밀폐시켜 지중의 이토가 내부로 유입됨을 방지할 수 있는 그 어떠한 수단도 구비되지 못하므로, 이로 인해 시공과정에서 이토가 상기 케이싱 파이프(10)의 내부로 쉽게 유입되어 보강부재와 혼입되므로 시공품질을 저하시킴은 무론 부실시공의 원인을 제공하는 심각한 폐단을 갖게 되었다.However, since the conventional shoe 20 simply repeats the opening and closing operation, it is not provided with any means capable of tightly sealing the casing pipe 10 to prevent the ground soil from flowing into the interior. Since Ito is easily introduced into the casing pipe 10 and mixed with the reinforcing member in the construction process, deterioration in construction quality has serious consequences for providing the cause of secondary construction.

또한, 종래의 슈(20)는 구조상 자중에 의해서 양측으로 벌려지게 되므로 상기 케이싱 파이프(10)를 지중으로 관입하기 위해서는 작업자가 상기 슈(20)의 외경을 별도의 와이어로프를 이용하여 감아서 서로 맞닿도록 고정한 후 관입공정을 진행하기 전에 다시 풀어야 하므로, 이로 인해 작업의 번거로움 및 불편함으로 인해서 시공효율이 저하되는 단점을 갖게 되었다.In addition, the conventional shoe 20 is open to both sides due to its own weight due to its structure, so that the operator can wind the outer diameter of the shoe 20 by using a separate wire rope in order to penetrate the casing pipe 10 into the ground. After fixing to abut it must be solved again before proceeding the penetration process, this has the disadvantage that the construction efficiency is reduced due to the hassle and inconvenience of work.

특히 종래의 슈(20)는 상기 케이싱 파이프(10)의 인발 공정에서 지중의 토압으로 인해서 양측으로 개방되는 속도가 늦어지게 되므로, 이로 인해 보강부재의 배출속도가 저하되어 전체적인 시공기간이 지연되는 문제점을 갖게 되었다.In particular, the conventional shoe 20 has a slow opening speed to both sides due to the earth pressure in the drawing process of the casing pipe 10, so that the discharge speed of the reinforcing member is lowered, thereby delaying the overall construction period Got

아울러 종래의 슈(20)는 구조상 굴착 및 관입공정을 진행하기에는 적합하나, 다짐작용을 통해서 연약지반을 개량하기 위한 공법에서는 비효율적이므로, 이로 인해 시공능률 및 활용범위가 극히 제한되는 한계를 갖게 되었다.In addition, the conventional shoe 20 is suitable for proceeding the excavation and penetration process, but inefficient in the construction method for improving the soft ground through the compaction action, this has a limit that the construction efficiency and utilization range is extremely limited.

따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서,Therefore, the present invention has been made to solve the above conventional problems,
