본 발명은 토류벽 시공공법에 관한 것으로, 특히 각 현장의 지반 즉, 암반 상태로 인하여 시트파일(Sheet-pile)을 항타할 때 근입 설계깊이를 지키지 못함에 따른 시공 불안정 및 그로 인한 위험을 효과적으로 보강할 수 있는 토류법 시공공법에 관한 것이다.The present invention relates to an earth wall construction method, and in particular, it is possible to effectively reinforce construction instability and its risks due to failure to keep the design depth when driving a sheet pile due to the ground of each site, that is, the rock state. It is about earthwork method construction method that can be done.

토목공사의 지하터파기 즉, 지하수위 아래의 굴착공사 시 일반적으로 활용하는 방토공법으로는 시트파일(S-pile)을 이용한 흙막이 가시설 공법이 적용된다.As a method of soil excavation that is generally used in underground excavation of civil engineering, that is, excavation under the groundwater level, a temporary block construction method using a sheet pile is applied.

이 공법은 도 1에 도시된 바와 같이, 하천 등 지하수위 아래의 토사 및 풍화암(R1) 굴착시 차수가 요구됨에 따라 시트파일(10)을 항타한 후 그 내부를 굴착하도록 하는 것인데, 설계상으로는 시트파일(10)의 근입깊이를 연암(R2)의 3-5M 까지 근입시키도록 되어 있다. 현재 이를 위해 워터젯(Water jet) 공법을 병행하여 시트파일(10)을 타입하고 있다.As shown in FIG. 1, this method is to excavate the inside of the seat pile 10 after driving the pile pile 10 as the order of excavation of soil and weathered rock (R1) under the groundwater level such as a river is required. The rooting depth of the pile 10 is pushed up to 3-5M of the soft rock R2. To this end, the sheet pile 10 is typed in parallel with a water jet method.

그러나 이러한 공법은 시공시 풍화암(R1)에 워터젯(24)를 병행하여 바이브로 햄머(Vibro hammer)(20)로 파일(Pile)을 근입시킬 때 항타에 많은 시간이 소요되고, 장시간 항타에 의한 마찰열로 파일의 변형 내지 손상을 입히게 되는 등 사실상 시트파일이 설계깊이 만큼의 근입이 불가능하였다.However, this method takes a lot of time to drive when the pile (Pile) in the Vibro hammer (20) in parallel with the water jet 24 to the weathered rock (R1) during construction, friction heat due to long-term driving In fact, the sheet pile could not be approached as deep as the design depth, such as deformation or damage of the furnace pile.

이로 인하여 시트파일(10)의 끝부분이 계획굴착고에 미치지 못하여 굴착 시 외부로 노출됨에 따라 파일의 저항값 σ=0이 되는 등 시공구조상 불안정하여 붕괴의 위험을 항상 내포하고 있었으며, 또 지금까지 마땅한 해결방법도 없었다.Due to this, the end of the sheet pile (10) did not reach the planned excavation height and exposed to the outside during excavation, the resistance value of the pile is σ = 0, such as the construction structure is unstable, and has always included the risk of collapse. There was no proper solution.

본 발명은 이러한 종래의 문제점을 해소하기 위해 창안한 것으로, 현장지반 여건에 맞게 시트파일을 항타 가능한 시공깊이로 근입한 후 엄지말뚝을 일정한 간격으로 항타하여 시트 파이프의 부족한 지지력을 보강하도록 함으로써 종래의 시공 의 불안전성을 효과적으로 극복할 수 있도록 한 토류벽 시공공법을 제공하는데 그 목적이 있다.The present invention has been devised to solve such a conventional problem, and by incorporating the seat pile into the construction depth capable of navigating to the site ground conditions, and then to drive the thumb pile at regular intervals to reinforce the insufficient bearing capacity of the seat pipe The purpose is to provide an earth wall construction method that can effectively overcome the instability of construction.

상기 목적을 달성하기 위한 본 발명의 토류벽 시공공법은, 하천 등 지하수위 아래 토사 및 풍화암 굴착시 이루어지는 시트파일(S-pile)을 이용한 가시설 공법에 있어서, 다수의 상기 시트파일을 연속적으로 항타하여 벽을 형성한 후 일정한 간격으로 시트파일의 내측부 원지반을 천공하고 이에 엄지말뚝인 H-pile을 항타하여 시트파일의 응력을 보강하도록 한 것을 특징으로 한다.The earth wall construction method of the present invention for achieving the above object, in the temporary construction method using a sheet pile (S-pile) made in the excavation of soil and weathered rock under the groundwater level, such as rivers, a plurality of the sheet pile is continuously driven to the wall After forming the perforated inner disc of the sheet pile at regular intervals and characterized in that to reinforce the stress of the sheet pile by driving the H-pile that is the thumb pile.

이의 이해를 돕기 위해 첨부도면을 참조하여 본 발명을 상세히 설명한다.The present invention will be described in detail with reference to the accompanying drawings in order to help understanding thereof.

도 4a,4b는 본 발명에 따른 토류벽 시공공법의 시공 순서도이고, 도 5a,5b는 H-pile(26)을 통해 보강된 본 발명 토류벽 시공공법의 요부 확대도이다. 도면부호 22는 워터펌프(Water pump)이고, 24는 워터젯(Water jet)이며, S는 구조물(교각)을 도시한 것이다.Figures 4a, 4b is a construction flowchart of the earth wall construction method according to the present invention, Figures 5a, 5b is an enlarged view of the main portion of the earth wall construction method of the present invention reinforced by the H-pile (26). Reference numeral 22 denotes a water pump, 24 denotes a water jet, and S denotes a structure (pier).

도면에서 보는 것과 같이, 본 발명에 따른 토류벽 시공공법은, 기본적으로 시트파일(S-pile)(10)을 항타하여 풍화암(R1)을 거쳐 연암(R2)의 3-5M 까지 근입시킴으로서 그 내부를 굴착할 수 있도록 하는 것이다.As shown in the drawings, the earth wall construction method according to the present invention, by basically driving the sheet pile (S-pile) 10 through the weathered rock (R1) to infiltrate up to 3-5M of soft rock (R2) by the inside To be excavated.

그 시공순서는 먼저 도 4a,4b와 같이, 시공될 계획굴착고(H)의 설계위치 둘레로 부지정리를 실시하고, 이에 워터젯 공법을 병행하여 바이브로햄머(20)로 시트파일(10)을 항타함으로써 지반의 구조에 따라 항타 가능한 근입깊이로 상기 시트파일(10)을 근입시킨다.4A and 4B, the construction procedure is carried out by arranging the site around the design position of the planned excavation height H to be constructed, and paralleling the waterjet method, the sheet pile 10 is formed by the vibrohammer 20. By driving, the seat pile 10 is driven to the indentation depth which can be driven according to the structure of the ground.

이어서 시트파일(10)의 내측 지반으로 천공한 후 이에 엄지말뚝 즉, H-pile(26)을 항타한다. 이때 상기 H-pile(26)은 계획굴착고(H) 이상으로 근입시킨다. 바람직하게는 연암(R2)의 3-5M 이상의 깊이로 근입시킨다.Subsequently, after drilling into the inner ground of the sheet pile 10, the thumb pile, that is, the H-pile 26 is driven. At this time, the H-pile 26 is driven into the planned excavation height (H) or more. Preferably it is rooted in the depth of 3-5M or more of the soft rock (R2).

또한 상기 H-pile(26)의 간격은 구조검토 결과, 대략 1.5-3M 특히 2M가 적당한 것으로 나타났다. 그리고 터파기 및 가시설을 실시하여 완료한다.In addition, the interval of the H-pile (26) as a result of the structural review, it was found that approximately 1.5-3M, especially 2M. And complete the excavation and provisional facilities.

도 5a는 H-pile(26)이 시트파일(10) 사이로 설치된 상태의 요부를 평면에서 도시한 것으로, H-pile(26)의 항타 완료 후에는 터파기가 실시되며, 그 과정에서 도시된 바와 같이 H-pile(26)들의 가로방향으로 띠장(28)을 대어 보강한다.FIG. 5A shows the main part of the state in which the H-pile 26 is installed between the sheet piles 10 in a plan view, and after the piercing of the H-pile 26 is completed, the trench is carried out, as shown in the process. Reinforce the band 28 in the transverse direction of the H-piles 26.

도 5b는 H-pile(26)의 하단이 계획굴착고(H) 보다 더 깊게 연암(R2)까지 근입되어 있음을 나타내 주며, 이와 같이 H-pile(26)이 설계깊이 또는 그 이상으로 충분히 근입됨에 따라 시트파일(10)이 계획굴착고(H)에 미치지 못하여 터파기시공 시 시트파일(10)의 하단이 노출되더라도 H-pile(26)이 시트파일(10)을 지지하기 때문에 안전한 시공을 담보할 수 있게 된다.5B shows that the lower end of the H-pile 26 is deeper in the soft rock R2 than the planned excavation height H. Thus, the H-pile 26 is sufficiently indented to the design depth or more. As the pile pile 10 does not reach the planned excavation height (H), even when the bottom of the sheet pile 10 is exposed during the excavation construction, the H-pile 26 supports the sheet pile 10 so that the construction is safe. It can be secured.

이상에서 살펴본 바와 같이 본 발명의 토류벽 시공공법은, 현장지반 여건에 맞게 시트파일을 근입 가능한 깊이로 항타한 후 그 내측으로 엄지말뚝인 H-pile을 일정한 간격으로 항타함으로서, 설계깊이에 미치지 못하게 설치됨에 따른 부족한 시트파일의 지지력을 효과적으로 보강할 수 있음은 물론이고, 그에 따른 종래의 시공의 불안정성을 구조적으로 보다 안정되게 극복할 수 있는 효과가 있다.As described above, the earth wall construction method of the present invention is installed so as not to reach the design depth by hitting the sheet pile at a predetermined interval after the seat pile is driven to a depth that can be accessed according to the site ground conditions. Of course, it is possible to effectively reinforce the bearing capacity of the insufficient sheet pile, and accordingly, there is an effect that can more structurally overcome the instability of the conventional construction accordingly.
