Description

{Quality check and reinforcing method of cast-in-placed-pile}

본 발명은 현장타설말뚝을 시공한 후 구체가 경화된 후에 품질을 확인하고 불량구간에 대해 보강할 수 있는 보강방법에 관한 것으로 구체적으로는 현장타설말뚝 공사 후 타설한 콘크리트 구체가 경화된 다음 구체 내에 빈 공간 등이 형성되거나 균열이 발생하여 구체의 기능이 상실 또는 저하된 경우를 확인할 수 있고 구체 불량구간과 주변지반의 공극을 채움할 수 있는 현장타설말뚝 품질확인 및 그 보강방법에 관한 것이다.The present invention relates to a reinforcement method capable of confirming the quality and reinforcing the defective section after the sphere is hardened after construction of the cast-in-place pile. It relates to the quality confirmation and reinforcement method of cast-in-place piles that can confirm the loss or deterioration of the function of the sphere due to the formation of empty spaces or cracks, and fill the voids of the sphere defective section and the surrounding ground.

CIP(Cast In Placed Pile) 공법은 현장에서 구조물의 말뚝기초를 시공하는 방법으로 말뚝기초 시공을 위한 천공경 내에 말뚝기초의 부재를 삽입하고 레미콘을 타설한 후 경화시간을 기다려 말뚝기초를 현장에서 시공하는 방법이다. 이 방법은 주열식으로 시공함으로써 지하구조물의 구축을 위한 굴착공사시 굴착으로 인한 주변의 지반붕괴를 방지하기 위한 흙막이 벽체를 구축하는 공법으로도 사용되고 있으며, 지반굴착 이전에 어스오거 등의 대구경 천공기로 필요한 깊이까지 천공한 후, 천공한 공 내에 현장콘크리트 말뚝을 연속하여 지중에 설치하여 주열식으로 흙막이 벽체를 형성하는 공법이다.The CIP (Cast In Placed Pile) method is a method of constructing the pile foundation of the structure on site. After inserting the member of the pile foundation into the borehole for pile foundation construction, pouring ready-mixed concrete, and waiting for curing time, the pile foundation is constructed on site. way to do it This method is also used as a construction method to build a retaining wall to prevent the collapse of the surrounding ground due to excavation during excavation for underground structures by constructing it as a main heat type. After drilling to the required depth, it is a construction method in which on-site concrete piles are continuously installed underground in the drilled hole to form a retaining wall in a columnar type.

이러한 CIP공법은 지반조건에 구애받지 않고 거의 모든 지반에 적용이 가능하며, 굴착이 완료되어 지하구조물을 구축할 때 지하 외부옹벽과의 합벽이 가능하고, 지하구조물을 근접하여 시공할 수 있어 터파기를 최소화시킬 수 있을 뿐 아니라 대지 내 지하구조물의 구축공간을 최대화할 수 있어 토지이용률을 극대화시킬 수 있는 장점이 있다.This CIP method can be applied to almost any ground regardless of ground conditions, and when excavation is completed, it can be combined with the underground external retaining wall when constructing an underground structure, and it is possible to construct the underground structure in close proximity. Not only can it be minimized, but it also has the advantage of maximizing the land use rate by maximizing the construction space of underground structures on the site.

한편, 지반의 조건으로 지중에서 물이 유동하거나 자갈, 전석 등의 암석, 암괴가 있는 경우에는 현장에서 타설한 레미콘이 천공경 내에 머무르지 않고 주변지반으로 흘러들어 요구되던 콘크리트 구체가 형성되지 않고 공극이 함께 형성되어 말뚝기초 또는 흙막이벽체로서의 기능을 기대할 수 없게 됨으로써 말뚝기초의 지지력이 확보되지 않거나 굴착시 누수, 유출수로 인해 큰 피해를 일으켜 이를 보강하는 공사를 별도로 수행하여야 하는 문제점이 발생하고 그 비용은 막대하다.On the other hand, if water flows underground as a condition of the ground, or there are rocks such as gravel or boulder, the ready-mixed concrete poured at the site does not stay within the borehole but flows into the surrounding ground, and the required concrete spheres are not formed and voids are formed. Due to these formations, the function as a pile foundation or retaining wall cannot be expected, so the bearing capacity of the pile foundation is not secured, or when excavation, leakage or runoff causes great damage, so that the construction to reinforce it must be performed separately, and the cost is huge

이러한 현실을 극복하기 위해 현장타설말뚝 시공시 검측공을 별도 설치하여 타설하고 경화 후에는 그 품질을 확인하기 위해 건전도시험을 수행하는 기법이 사용되고 있으나 이는 시험후 불량구간에 대해 보강을 하기 위해서는 별도의 천공, 그라우팅을 실시하여야 하는 기법으로 시험, 천공, 그라우팅을 실시하여야 하는 함으로써 많은 시간과 큰 비용이 발생하게 되어 개선이 요구된다.In order to overcome this reality, the technique of performing a soundness test to check the quality after installing and pouring a separate inspection hole during the construction of cast-in-place piles is used. It is a technique that requires drilling and grouting, and as a result, a lot of time and large costs are incurred by testing, drilling, and grouting, and improvement is required.
