(4) processing, but having a solid foundation by processing the grouting (4) to a predetermined height of the replacement material (3), and then by building the upper structure (5) on top of the foundation, a stable and robust structure It is about a devise that can be built.
Description
본 고안은 연약지반상에 계선안 또는 물량장등의 구조물을 축조시 기초지반 보강을 위하여 실시하는 그라우팅 지반개량에 관한 것으로서, 특히 그라우팅 지반개량후의 취약점인 표면의 상태를 하부의 그라우팅과 마찬가지로 균일하고 튼튼한 기초지반을 얻고자 안출한 그라우팅 지반 개량 구조체에 관한것이다.The present invention relates to the grouting ground improvement to be carried out for reinforcing the foundation ground when constructing a structure such as a mooring line or a volume field on a soft ground, and in particular, the surface state, which is a weak point after the grouting ground improvement, is uniform and strong as the lower grouting. The present invention relates to a grouting ground improvement structure designed to obtain a foundation ground.
연약지반에는 일반적인 토양보다 토립자와 토립자 사이의 공극에 차있는 공기 및 물등이 많으므로 인하여, 그 상부에 구조물을 구축시 그 상부 구조물의 자중에 의해 취약부분의 지반이 침하되어, 상부 구조물의 하중 불균일에 따른 비틀림등의 현상이 발생되어 구조물 전체의 안정성에 심각한 문제점이 대두될 수 있으므로, 이러한 문제점을 해결하기 위하여 일반적으로 고압으로 연약지반의 하부에 있는 원지반까지 경화제(주로 시멘트 밀크)등을 강제 압밀하여 경화시키는 그라우팅을 한 후, 그 상부에 구조물을 구축하였다.In soft ground, there are more air and water filled in the voids between the granules and the granules than the general soil, so when the structure is constructed on the upper part, the ground of the weak part is subsided by the weight of the upper structure, resulting in uneven load of the upper structure. As a phenomenon such as twisting may occur, serious problems may arise in the stability of the structure as a whole. In order to solve this problem, a hardening agent (mainly cement milk), etc., is forcibly condensed to the original ground under the soft ground at high pressure. After the grouting to harden by, to build a structure on top.
상기와 같이 연약지반의 개량을 위한 그라우팅시에, 연약지반 하부측은 어느정도 일정한 압력과 균일한 슬럼프치를 내재한 주변 조건을 가지므로 필요한 범위의 연약층이 개량되나, 지반의 상측 표면에 인접해서는 연약지반의 정도 차이에 의해 좌,우 및 상,하단의 압력이 균일하지 못하므로 인하여, 고압으로 압밀하는 경화제등이 연약지반의 상측 표면부의 가장 연약한 부분으로 누설되어, 연약지반의 표면측은 원하는 강도와 표면형상의 그라우팅 작업이 되지 않고, 표면상태가 불량하고 취약한 상태로 마무리되므로, 상부 구조물 구축시 표면변위에 따르는 하자발생의 요인이 되었다.As described above, when grouting for the improvement of soft ground, the lower part of the soft ground has a certain constant pressure and ambient conditions inherent to a uniform slump, so that the soft layer in the required range is improved, but adjacent to the upper surface of the ground, Due to the difference in accuracy, the pressures of the left, right, upper and lower ends are not uniform, so that the hardener, which is consolidated at high pressure, leaks into the softest part of the upper surface of the soft ground, and the surface of the soft ground has the desired strength and surface shape. It is not grouting work, and the surface condition is poor and finished in a vulnerable state, which is a factor of defect occurrence due to surface displacement when constructing the upper structure.

본 고안은 상기와 같이 연약지반 개량을 위한 그라우팅 후에도 그 표면의 처리가 취약한 상태로 남아, 이러한 상태의 그라우팅 선단에 연설되게 구축하는 상부 구조물 또한 불안정 하던 것을, 불량과 위험요소가 발생되지 못하도록 안출한 고안으로서 본 고안의 구성을 첨부한 도면에 의거하여 상술하면 다음과 같다.The present invention, after the grouting to improve the soft ground as described above, the surface of the surface remains in a vulnerable state, the upper structure that is built to be addressed to the grouting tip of this state is also unstable, to prevent the occurrence of defects and risks The present invention will be described in detail with reference to the accompanying drawings as a design.
본 고안상으로 실시되는 4각 상자체로 되는 콘크리트 중공블럭(1)을 별도로 제작하여, 그라우팅 처리를 하고자 하는 연약지반의 표면(2a)에 재치후, 그 중공블럭(1) 내측의 연약지반(2)의 토사를 굴토하여, 중공블럭(1)을 연약지반의 표면(2a)과 같은 높이가 되도록 침하시키고, 상기 중공블럭(1) 내부를 양질의 모래등과 같은 치환재(3)로 개량한 후, 중공블럭(1) 하부의 연약지반(2)에 그라우팅(4) 처리를 하되, 상기의 중공블럭(1) 내부에 치환하여 채워진 치환재(3)의 하부측 소정의 높이까지 그라우팅(4) 처리하므로서, 중공블럭(1) 내측 외곽의 압력과 모래등으로 치환된 치환재(3)의 일정한 상부압력에 의해, 하부의 연약지반(2) 그라우팅(4) 처리부와 상측인 중공블럭(1) 내부의 치환재(3)가 일체가 되며, 상기와 같이 그라우팅(4) 처리 작업이 완료되면 그 상부에 상부 구조물(5)을 구축하므로서 본 고안상으로 실시되는 중공블럭을 이용한 그라우팅 지반개량 구조체가 완료된다.According to the present invention, a concrete hollow block 1 made of a quadrangular box body is separately manufactured and placed on the surface 2a of the soft ground to be grouted, and then the soft ground 2 inside the hollow block 1 is formed. ), The hollow block (1) is settled to the same height as the surface (2a) of the soft ground, and the inside of the hollow block (1) is improved with a substitute material (3) such as high-quality sand, etc. Then, the grouting (4) treatment on the soft ground (2) below the hollow block (1), the grouting (4) to a predetermined height of the lower side of the substitution material (3) filled by replacing the inside of the hollow block (1) ), The hollow block (1) above the soft ground (2) grouting (4) processing unit of the lower soft ground (2) by the constant upper pressure of the substitution material (3) replaced with the sand and the pressure of the inside of the hollow block (1). ) Substituents 3 in the interior are integrated, and when the grouting (4) processing operation is completed as above, The grouting soil improvement structures with hollow blocks to be carried out in the subject innovation a hameuroseo building unit structures (5) is completed.
상기와 같이 중공블럭(1)을 이용하여 그 내부의 연약지반(2) 토사를 양질의 모래등의 치환재(3)로 치환한 후 그 하부를 그라우팅(4) 처리하므로서, 연약지반(2) 상측부에 치환한 양질의 치환재(3)의 균일한 압력과 중공블럭(1) 내측 외각부의 압력에 의해, 그라우팅(4) 처리가 연약지반(2) 표면(2a)부에 이러러서도 균일한 그라우팅(4) 처리가 가능하며, 그로인해 중공블럭(1) 내부의 치환재(3)나 그 하부의 연약지반(2) 그라우팅(4) 처리부의 이동이나 유실이 없어서 그위에 구축한 상부 구조물(5) 또한 안정되고 튼튼한 구조물을 구축할 수 있는 효과가 있다.As described above, the soft ground (2) by using the hollow block (1) is replaced with a substituting material (3), such as sand of good quality, and then the lower part of the grouting process (4), the soft ground (2) Even when the grouting process 4 is in the soft ground 2 surface part 2a by the uniform pressure of the high-quality substitute material 3 substituted in the upper part and the pressure of the outer outer part of the hollow block 1, it is uniform. It is possible to process one grouting (4), so that there is no displacement or loss of the substituting material (3) inside the hollow block (1) or the soft ground (2) grouting (4) processing part therein, and the upper structure constructed thereon (5) It also has the effect of building a stable and robust structure.
