2열 자립식 흙막이 시공에서의 전열·후열 말뚝 연결재 연결구조{CONNECTION STRUCTURE OF BEFORE AND AFTER PILE CONNECTION FOR TWO ROWS PILE CONSTRUCTION}CONNECTION STRUCTURE OF BEFORE AND AFTER PILE CONNECTION FOR TWO ROWS PILE CONSTRUCTION}

본 발명은 2열 자립식 흙막이 시공에서의 전열·후열 말뚝 연결재 연결구조에 관한 것으로, 구체적으로는 본 발명의 출원인에 의해 선출원되어 공개된 대한민국 공개특허 제10-2011-0136143호에 따른 "전열·후열 말뚝 연결재 및 이를 이용한 2열 자립식 흙막이 시공방법"를 개량하여, 공사기간을 더욱 단축시키고, 공사비를 더욱 절감하면서도 토압을 줄이고, 대지 여유 공간이 없는 곳에도 적용할 수 있도록 하는 2열 자립식 흙막이 시공에서의 전열·후열 말뚝 연결재 연결구조에 관한 것이다.
The present invention relates to a heat transfer and post heat pile connection member connecting structure in a two-stage self-supporting soil construction, and specifically, according to Korean Patent Application Publication No. 10-2011-0136143 published and filed by the applicant of the present invention. 2 row freestanding type that improves the construction period, reduces construction pressure, reduces earth pressure and reduces land pressure, and can be applied even where there is no land free space. The present invention relates to a connection structure of heat transfer post-heat pile pile connectors in construction of a piling.

일반적으로 성토, 절토, 굴착 등을 실시하게 되면 통상 비탈면을 두어 지반의 안정을 유지시켜 주고 있지만, 토지의 이용도를 더욱 효과적으로 확보하거나 도시내의 구조물의 기초 및 건물의 지하실을 시공하기 위한 굴착시에는 비탈면을 두지 못하고 통상 연직굴착을 실시하게 된다.
In general, when the ground, cut, excavation, etc. are carried out, the slopes are generally maintained to maintain the stability of the ground. Normally, vertical excavation is performed without a slope.

따라서 연직굴착으로 인한 인접 지반의 붕괴를 방지하기 위해 연직면 주변에 2열 자립식 흙막이벽을 필수적으로 설치하게 되는데, 이를 2열 자립식 흙막이 시공이라고 한다.
Therefore, in order to prevent the collapse of the adjacent ground due to the vertical excavation, a two-row freestanding mud wall is essentially installed around the vertical surface, which is called a two-row freestanding mudguard construction.

종래 2열 자립식 흙막이 시공방법은 도 1에 도시된 바와 같이, 일정간격으로 엄지말뚝(H빔)(100,200)을 2열로 항타하거나, 천공 후 삽입하는 방식에 의해 근입하고, 터파기를 진행하면서 토류판(10)을 각 엄지말뚝(100,200) 사이에 끼워 넣어 벽체를 형성한다.
In the conventional two-row self-supporting soil construction method, as shown in Figure 1, by pressing the thumb pile (H beam) (100,200) in two rows at a predetermined interval, or by inserting after punching, earth plate while proceeding the trench (10) is sandwiched between each thumb pile (100,200) to form a wall.

이후, 상기 엄지말뚝(100,200)의 상부에 횡방향 연결재(H빔)(300)와 종방향 띠장(H빔)(231)을 배치하여, 각 엄지말뚝(100,200)을 연결함으로써, 토압을 버티도록 하였다.
Subsequently, a horizontal connecting member (H beam) 300 and a longitudinal band length (H beam) 231 are disposed on the top of the thumb pile 100 and 200 to connect the thumb piles 100 and 200 so as to sustain earth pressure. It was.

하지만, 상기와 같은 종래의 2열 자립식 흙막이 시공방법은 횡방향 연결재 를 배치하기 위한 시공방법이 복잡하여 공사기간이 길어질 뿐만 아니라, 상기 각 연결재가 H빔으로 이루어짐에 따라 고가의 H빔의 소모가 증가하고, 횡방향 연결재의 끝단면을 띠장과 일치시키기 위해 횡방향 연결재의 양측면을 절단해야 하는 등 H빔의 낭비 또한 심하여 공사비용이 급격히 증가하게 되는 문제점이 있었다.
However, the conventional two-row self-supporting earthen construction method as described above has a complicated construction method for arranging the transverse connectors, which increases the construction period, and consumes expensive H beams as the respective connectors are made of H beams. H and waste of the H beam is also severe, such as the need to cut both sides of the lateral coupling member to match the end face of the lateral coupling member with the band, there is a problem that the construction cost increases rapidly.

따라서, 상기와 같은 문제점을 해결하기 위해, 본 발명의 출원인은 특허문헌 1인 대한민국 공개특허 제10-2011-0136143호를 선출원한 바 있다.

Specifically, as shown in FIG. 2, the patent document 1 includes a connector mounting hole 20 coupled to each of the first belt length 400 and the second belt length 500, and the connector mounting hole 20. Coupled to the first and second strips through the medium, and comprises a ring-shaped connecting member 30 for connecting the first strip 400 and the second strip 500, it is made of an expensive H beam In addition to reducing the cost of construction by replacing the connecting rod with a low-cost round bar, it is possible to easily couple the round bar to the thumb pile, thereby reducing the construction period.
