Description

시트파일 선행 천공가이드{Sheet Pile Advance Drilling Guide} Sheet Pile Advance Drilling Guide

본 발명은 시트파일 선행 천공가이드에 관한 것으로서, 더욱 상세하게는 지반 천공작업시 케이싱의 수직도를 지지하기 위한 가이드 기능을 수행하며 차수벽 생성에 있어 일괄적인 겹침시공과 종횡의 효율적인 일렬작업을 가능케 하는 천공가이드 구조에 관한 것이다.The present invention relates to a sheet pile precedent drilling guide, and more particularly, performs a guide function to support the verticality of the casing during ground drilling, and enables batch overlapping construction and efficient vertical and horizontal aligning work in the creation of an order wall. It relates to a perforation guide structure.

일반적으로 건축공사 또는 토목공사시 토사가 흘러내리거나 지반이 붕괴되는 것을 방지하거나 차수작업을 목적으로 여러 형태의 흙막이 공법이 실시된다.In general, various types of retaining methods are implemented for the purpose of preventing soil from flowing down or the ground from collapsing during construction or civil engineering work, or for the purpose of waterproofing work.

이와 같은 공법 중 대표적인 흙막이 공법으로, C.I.P(Cast-In-Placed-Pile) 공법, H파일 토류벽공법, SCW(Soil Cement Wall)공법, SCW(SOIL CEMENT WALL)병용 H파일 토류벽 공법이 있고, 차수 및 흙막이 기능이 동시에 달성하는 공법으로 시트파일(Sheet-Pile)공법 등이 있다.Among these methods, representative retaining methods include C.I.P (Cast-In-Placed-Pile) method, H-pillar earth wall method, SCW (Soil Cement Wall) method, and SCW (SOIL CEMENT WALL) combined H-pillar earth wall construction method. There is a sheet-pile method, etc., as a method of achieving the retaining function at the same time.

그중 시트파일 공법은 차수기능 및 흙막이 기능을 동시에 제공하기 위해 크레인을 이용한 진동 해머로 시트파일을 직타하여 지반에 강제 삽입시키는 공법으로, 강도와 내구성이 우수한 시트파일을 사용할 경우에는 연속벽형 강성체로서의 토류벽 역활을 충분히 할 수 있으며, 접촉부의 수밀성이 우수하여 차수 효과를 얻을 수 있는 공법이다.Among them, the sheet pile method is a method in which the sheet pile is directly hit with a vibrating hammer using a crane and forcibly inserted into the ground in order to provide a water-repellent function and a retaining function at the same time. It is a construction method that can sufficiently play the role of an earth wall, and has excellent watertightness of the contact part to obtain a water-repellent effect.

이러한, 시트파일 공법은 수분 함량이 많은 연약 지반이나 점토질 지반에 적용시 보다 강한 지지력을 얻기 위해 보통 지반 굴착 장비를 이용하여 천공용 T4 해머와 케이싱과 스크류를 이용하여 암반부까지 다수개의 천공홀이 중첩되도록 천공한 상태에서 시트파일을 중첩된 천공부를 통해 암반부까지 진동 해머를 이용하여 매립 시킬 수 있다.In this sheet pile method, in order to obtain stronger bearing capacity when applied to soft or clay soils with high moisture content, a plurality of perforation holes are made up to the bedrock using a T4 hammer for drilling, a casing and a screw using a common ground excavation equipment. In the state of being perforated so as to overlap, the sheet pile can be embedded through the overlapped perforation to the bedrock using a vibrating hammer.

한편, 종래 기술에서는 상기 케이싱을 지반에 수직으로 삽입되도록 가이드 하는 기술로는 천공 가이드 구조물이 사용되어지게 되는데, 이러한 천공 가이드는 반원가이드 홈이 길이방향으로 배열된 가이드본체를 2개가 쌍을 이루어서 서로 마주보도록 배치시킴으로써 케이싱이 통과하기 위한 원형의 가이드홈을 구성하게 된다.On the other hand, in the prior art, a drilling guide structure is used as a technique for guiding the casing to be vertically inserted into the ground. This drilling guide consists of two guide bodies in which semicircular guide grooves are arranged in the longitudinal direction in pairs to form a pair. By arranging to face each other, a circular guide groove is formed for the casing to pass through.

그러나, 종래 천공 가이드는 상판면에 돌기나 별도의 부착물이 돌출 형태로 구비되어 있기 때문에 작업차량(파일드라이버, 포크레인 등) 진입에 장애 요소가 됨과 함께 작업자의 보행시 안전사고 발생의 위험이 발생되는 문제점이 있었다.However, since the conventional drilling guide is provided with a protrusion or a separate attachment on the top surface in a protruding form, it becomes an obstacle to entry of a work vehicle (pile driver, fork crane, etc.) There was a problem.

이하, 본 발명의 구체적인 실시 예를 첨부 도면을 참조하여 상세히 살펴보기로 한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

먼저, 본 발명의 제1 실시 예에 따른 시트파일 선행 천공가이드 구조를 도 1 내지 도 5를 통해 살펴보면 다음과 같다.First, the structure of the sheet pile prior drilling guide according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 5 as follows.

본 실시 예에서의 천공가이드는, 원통 형상의 케이싱의 삽입을 가이드하기 위한 반원 형상의 가이드홈(11)이 가이드본체(10) 일측면에 형성된 구조를 이루게 된다.The perforation guide in this embodiment has a structure in which a semicircular guide groove 11 for guiding the insertion of the cylindrical casing is formed on one side of the guide body 10 .

특히, 상기 가이드본체(10)의 상면은 돌출 구조물이 없는 평탄면(12)을 이루게 된다.In particular, the upper surface of the guide body 10 forms a flat surface 12 without a protruding structure.

또한, 가이드본체(10) 상부에는 위치 고정을 위한 고정빔(30)의 삽입이 이루어질 수 있도록 상하로 관통된 형태의 빔고정부(13) 및 샤클고리 인양을 위해 철판에 통공이 형성된 샤클리브(14)가 구비된다.In addition, in the upper portion of the guide body 10, a beam fixing part 13 penetrating up and down so that the fixing beam 30 for fixing a position can be inserted, and a shackle rib 14 having a hole in the iron plate for lifting the shackle ring. ) is provided.

본 실시 예에서의 가이드본체(10)는 2개가 쌍을 이루어서 터파기 지면에 설치가 이루어지되, 양단부에는 상호 연결을 위한 체결볼트의 체결이 이루어질 수 있도록 볼트홈(15)이 다층 구조를 이루어 구비됨과 함께 가이드본체(10)의 외측 모서리부위에도 연속적인 연결 시공이 이루어질 수 있도록 체결볼트의 체결이 이루어지는 볼트홈(16)이 다층 구조를 이루어 구비된 것을 확인할 수 있다.In this embodiment, the guide body 10 in this embodiment forms a pair and is installed on the ground of the excavation, and at both ends, the bolt groove 15 is provided with a multi-layer structure so that the fastening bolts for interconnection can be fastened. It can be seen that the bolt groove 16 through which the fastening bolts are fastened has a multi-layered structure so that continuous connection construction can be made even at the outer edge of the guide body 10.

도면 중 미설명 부호 16a는 볼트공을 나타낸다.In the drawings, unexplained reference numeral 16a denotes a bolt hole.

이와 같은 구성을 이루는 본 발명 천공가이드의 사용에 따른 작용효과를 살펴보기로 한다.Let's take a look at the effect of the use of the present invention perforation guide constituting such a configuration.

본 발명의 천공가이드는 터파기가 이루어진 지면 위에 배치가 이루어지게 되는데, 도 1 및 도 3에서와같이 2개의 가이드본체(10)가 쌍을 이루는 가운데 흙막이 벽체를 구성하기 위한 케이싱(미도시)의 삽입이 이루어지는 위치에 설치가 이루어지게 된다.The drilling guide of the present invention is arranged on the ground where the excavation is made. As in FIGS. 1 and 3, the two guide bodies 10 are paired with a casing (not shown) for configuring the retaining wall in the middle. Installation is made at the location where this is made.

이때, 2개의 가이드본체(10)는 양측의 볼트홈(15)에서 체결볼트(17)에 의해 상호 간에 일체형으로 결합된 상태를 이루게 되며, 빔 고정부(13)에 H빔 형태의 고정빔(30)을 고정시킨 상태에서 항타 작업이 이루어지게 된다.At this time, the two guide bodies 10 are integrally coupled to each other by the fastening bolts 17 in the bolt grooves 15 on both sides, and the H-beam-shaped fixing beam ( 30) is fixed, the driving operation is performed.

이러한 항타작업 과정에서, 본 발명의 천공가이드는 가이드본체(10)의 상면이 평탄면(12)을 이루고 있기 때문에 작업자의 이동 과정에서 발에 돌출 구조물이 걸림으로 인한 부상 등의 안전사고 발생이 방지되어질 수 있게 된다.In the course of this driving operation, in the drilling guide of the present invention, since the upper surface of the guide body 10 forms a flat surface 12, safety accidents such as injuries caused by the protruding structure caught on the foot during the movement of the operator are prevented. can become

그리고, 일정 길이를 이루는 본 발명의 가이드본체(10)를 연속적으로 연결 설치코자 하는 경우에는 모서리 부위에 구비된 볼트홈(16)에서의 볼트 체결에 따른 연결이 이루어질 수 있게 된다.And, in the case of continuously connecting and installing the guide body 10 of the present invention forming a predetermined length, the connection can be made according to bolting in the bolt groove 16 provided in the corner portion.

또한, 이러한 가이드본체(10)의 배치 또는 위치 이동을 위한 인양작업시에는 샤클리브(14)를 이용하여 인양작업이 효율적으로 이루어질 수 있게 됨을 알 수 있다.In addition, it can be seen that the lifting operation can be efficiently performed using the shackleive 14 during the lifting operation for disposition or position movement of the guide body 10 .

한편, 항타 작업이 완료되면 도 6 및 도 7에서와같이 마지막 항에 고정파일(20)로 고정시킨 상태에서 빔 고정부(13)로부터 고정빔(30)을 제거 하여 일측 고정상태를 해제한 후 천공가이드를 고정파일(20)을 축으로 하여 180도 회동시켜서 반대 측으로 이동 배치한 후 다시 고정빔(30)으로 위치 고정한 상태에서 다음 항타작업이 이루어질 수 있게 되어 흙막이 공사 시 연속 작업이 용이하게 이루어질 수 있게 됨을 알 수 있다.On the other hand, when the driving operation is completed, remove the fixed beam 30 from the beam fixing unit 13 in the state fixed with the fixing pile 20 in the last term as in FIGS. 6 and 7 to release the fixed state on one side. After the drilling guide is rotated 180 degrees about the fixed pile 20 as an axis and moved to the opposite side, the next driving operation can be performed while the position is fixed with the fixed beam 30 again, so that continuous work can be easily performed during retaining construction. It can be seen that

따라서 본 발명의 시트파일 천공가이드는, 상부면이 별도의 부착물이 없는 평탄면을 이루고 있기 때문에 작업자의 보행 간섭에 따른 안전사고 발생이 방지됨과 함께 작업차량 진입시 방해요소가 제거될 수 있는 효과를 나타낸다.Therefore, since the sheet pile drilling guide of the present invention has a flat surface with no separate attachment on the upper surface, safety accidents due to interference of workers from walking are prevented and obstructions can be removed when entering the work vehicle. .

또한, 천공가이드의 연속적인 연결 작업이 보다 신속하고 용이하게 이루어질 수 있게 되어 작업효율을 향상시키는 이점을 나타낸다.In addition, the continuous connection operation of the perforation guide can be made more quickly and easily, thereby showing the advantage of improving the working efficiency.

한편, 도 8은 본 발명의 다른 실시 예에 따른 구성을 나타낸 것으로서, 가이드본체(10)의 상면을 이루는 평탄면(12)에는 미끄럼 방지를 위한 마찰 코팅층(12a)이 코팅 형성된다.Meanwhile, FIG. 8 shows a configuration according to another embodiment of the present invention, and a friction coating layer 12a for preventing slippage is coated on the flat surface 12 constituting the upper surface of the guide body 10 .

이때, 상기 마찰 코팅층(12a)은 멜리민수지 25~45중량%, 스테아린산 칼슘 10~30중량%, 폴리우레탄 10~25중량%, 폴리불화비닐리덴 5~20중량%, 티타늄디옥사이드 1~10중량%, 규소수지 1~10중량%, 싸이오황산소듐 1~5중량%, 이산화염소 1~5중량%의 비율로 혼합이 이루어짐이 바람직하다.At this time, the friction coating layer (12a) is 25 to 45% by weight of melamine resin, 10 to 30% by weight of calcium stearate, 10 to 25% by weight of polyurethane, 5 to 20% by weight of polyvinylidene fluoride, 1 to 10% by weight of titanium dioxide %, silicon resin 1 to 10% by weight, sodium thiosulfate 1 to 5% by weight, chlorine dioxide is preferably mixed in a ratio of 1 to 5% by weight.

이와 같이 형성된 마찰 코팅층(12a)은 스테아린산 칼슘 및 폴리우레탄 성분이 혼합되어 있기 때문에 마찰력 향상이 이루어지게 되어, 빗물 등에 의한 작업자의 미끄러짐 사고를 방지할 수 있게 된다.Since the friction coating layer 12a formed in this way is mixed with calcium stearate and a polyurethane component, frictional force is improved, so that it is possible to prevent an operator slipping accident due to rainwater or the like.

또한, 마찰 코팅층(12a)에 혼합된 폴리불화비닐리덴은 혼합 성분 상호간의 결합력 강화에 따른 밀도를 증대시키며, 티타늄디옥사이드 및 규소수지는 코팅층의 내구성 강화에 따른 크랙 발생을 방지하고, 싸이오황산소듐은 멜라민수지의 활성화에 따른 경화현상 발생을 방지하고, 이산화염소는 코팅층의 변색 및 산화 발생을 방지하는 기능을 수행하게 된다.In addition, polyvinylidene fluoride mixed in the friction coating layer 12a increases the density by strengthening the bonding force between the mixing components, and titanium dioxide and silicon resin prevent cracks due to strengthening the durability of the coating layer, and sodium thiosulfate Silver prevents the occurrence of hardening due to the activation of the melamine resin, and chlorine dioxide functions to prevent discoloration and oxidation of the coating layer.
