본 고안은 방파제 또는 호안의 기초지반 개량에 대한 것으로서, 특히 그라우팅 공법에 의한 지반 개량시 원지반 표면의 연약부분을 보강하는 블럭에 관한 것이다.The present invention relates to the improvement of the basic ground of the breakwater or revetment, and more particularly, to a block for reinforcing the soft part of the surface of the ground when the ground is improved by the grouting method.

통상적으로 해저의 연약 지반상에 축조되는 구조물인 방파제 또는 육지와 바다가 연하는 호안등의 연약한 기초 지반의 개량은, 그 목적과 규모,형식 사용기간 등을 고려하여 기초 지반 개량방법이 결정되지만, 일반적으로 콘크리트 파일등을 항타하여 기초지반을 지지 시키는 파일 항타공법, 양질의 사석등으로 치환하여 되메우는 치환공법, 급결 몰탈등의 주입재(注入材)를 주입하여 응고시키는 그라우팅 공법, 강제 침하공법 등이 사용되며, 그 중에서 본 고안은 그라우팅 공법으로 기초 지반을 개량할 시에, 그 원지반과 상부 구축물 사이의 표면처리에 관한 것으로서, 종래는 상기와 같이 그라우팅 공법에 의해 기초 지반을 개량한 후 그 원지반 위에 사석등으로 마운드를 형성하고 상부 구조를 구축하였다.In general, the improvement of soft foundations such as breakwater, which is a structure built on the soft ground of the seabed, or shores and seashores, is determined by considering the purpose, size, type of use, etc. Generally, pile anti-punching method to support the foundation ground by crushing concrete pile etc., substitution method to be replaced by high quality sandstone, grouting method to inject and solidify the injection material such as quick mortar, forced sinking method, etc. The present invention relates to the surface treatment between the base and the upper structure when the foundation is improved by the grouting method, and conventionally, after the foundation is improved by the grouting method as described above. A mound was formed on the top of the building and a superstructure was constructed.

상기와 같이 그라우팅 공법에 의한 기초 지반 개량시는 기초 지반은 튼튼하게 보강이 되나 그 표면은 연약지반인 원지반 상태가 그대로 잔유하여 상부 구축물의 구축시 불안정한 상태로 구축이 되며, 그로인해 지진이나 횡방향 응력에 의해 구축물이 틀어지거나 변형되어 안정성을 저해하는 등의 문제점이 있었다.When the foundation ground is improved by the grouting method as described above, the foundation ground is firmly reinforcement, but the surface of the ground ground is soft as it is, so it is built in an unstable state when constructing the upper construction. There was a problem such that the structure is distorted or deformed by the stress, thereby impairing stability.

따라서 본 고안은 그라우팅 공법에 의한 연약지반 개량후 잔유하는 연약지반 표면을 보강하기 위하여 사용될 수 있도록 하는 전용 블럭으로서 그 구조 구성을 첨부한 도면에 의거하여 상술하면 다음과 같다.Therefore, the present invention is a block dedicated to be used to reinforce the soft ground surface remaining after the soft ground improvement by the grouting method in detail based on the accompanying drawings as follows.

콘크리트 재료로 되는 소정의 두께와 가로와 세로를 가지는 정방형인 판상체(1)의 4모서리부에, 각각 소정의 가로폭과 세로폭과 높이를 가지며 상협하광한 마름모꼴 입방체(2)를 상측면에 일체로 형성함과 아울러, 동일한 각 모서리 하측면으로도 상기의 마름모꼴 입방체(2) 구성과 대칭되는 마름모꼴 입방체(2a)의 구성을 판상체(1)와 일체로 형성하고, 상기 정방형 판상체(1)의 4두께면 중앙부에는 각각 소정의 깊이와 길이로 되는 요입부(3)를 구비하여, 블럭(B)을 조합시 블럭(B)간에 공극이 형성되도록 하며, 또한 블럭(B)의 중앙부에는 소정의 폭과 길이로 되는 직사각 통수공(4)을 천공하여서 본 고안상으로 실시되는 블럭(B)의 구조 구성이 이루어진다.In the four corner portions of the square plate-shaped object 1 having a predetermined thickness and width and length of a concrete material, a rhombic cube 2 having a predetermined width, height and height and having a predetermined width is respectively disposed on the upper side. In addition to being formed integrally, the rhombic cube 2a, which is also symmetrical to the rhombic cube 2 configuration, is formed integrally with the plate-like body 1, and the square plate-shaped object 1 In the central portion of the four-thickness surface of), each of the recesses 3 having a predetermined depth and length is provided, so that a gap is formed between the blocks B when the blocks B are combined, and at the center of the blocks B, The structure configuration of the block B implemented according to the present invention is made by drilling a rectangular through hole 4 having a predetermined width and length.

도면중 미설명 부호인 (5)는 그물망이며, (6)은 마운드, (7)은 사석을 나타내며, (8)은 상부 구축물, (9)는 그라우팅을 한 지반을 나타낸다.In the figure, reference numeral 5 denotes a mesh, 6 denotes a mound, 7 denotes a sandstone, 8 denotes an upper structure, and 9 denotes grouted ground.

한편, 상기와 같이 구성된 블럭(B)을 그라우팅(9) 공법에 의해 기초 지반 개량을 한 표면에 조밀하게 적층하고, 그 위에 와이어나 체인등의 그물망(5)을 설치하여 블럭(B)의 이탈을 방지하며, 다시 그 위에 사석(7)등을 투하하여 마운드(6)를 넓게 구성한 후 그 위에 방파제 또는 호안등의 상부 구축물(8)을 구축하게 된다.On the other hand, the block B constructed as described above is densely stacked on the surface of the ground improved by the grouting 9 method, and a net 5 such as a wire or a chain is provided thereon to remove the block B. To prevent, and again dropping the sandstone (7) on it to form a wide mound (6) and then to build an upper structure (8) of breakwater or shelter thereon.

상기에서와 같이 그라우팅(9) 공법으로 기초 지반을 개량후 잔유하는 연약지반 위에 본 고안상으로 실시되는 블럭(B)을 평면적으로 밀착하여 포설하므로서, 더욱 튼튼한 기초 지반이 구성되며, 하측의 마름모꼴 입방체(2)가 연약지반 속으로 매입되므로서 기초 지반과 블럭(B)이 견고하게 밀착되고, 상측의 그물망(5)에 의해 블럭(B)간 이탈을 방지하며, 그 상면에 마운드(6)를 형성하는 사석(7)을 블럭(B) 상측의 요철부 사이에 충전하므로, 본 고안인 블럭(B)이 마운드(6)와 기초 지반과의 결속력을 강하게 하는 역활을 하여, 상부 구축물(8) 또한 변형이나 이탈등이 없는 안정적인 구조물을 구축할 수가 있다.As described above, by laying the block (B) according to the present invention in planar contact with the ground ground on the soft ground remaining after improving the foundation ground by the grouting (9) method, a more robust foundation ground is formed, and the lower lozenge cube (2) is embedded into the soft ground, so that the foundation ground and the block (B) are firmly adhered to each other, and the separation of the blocks (B) is prevented by the upper mesh (5), and the mound (6) is placed on the upper surface thereof. Since the formed sandstone 7 is filled between the concave-convex portions on the upper side of the block B, the block B of the present invention plays a role of strengthening the binding force between the mound 6 and the foundation ground, and thus the upper structure 8 In addition, it is possible to construct a stable structure without deformation and departure.
