Abstract

A device for measuring displacement of a pile displacement measuring sensor is provided to perform reliable construction, prevent faulty construction, and record a precise work process. A displacement measuring device(70) for a pile displacement measuring sensor includes a heavy weight(71), a spring(72), an electro-optical distance meter(73), and a support(74). The heavy weight is hung down an upper side of the support by the spring. The electro-optical distance meter is installed at the upper or lower side of the support to measure a distance between the upper or lower side of the support and the heavy weight. The heavy weight doesn't move even when the support vibrates up and down in a moment.

건설공사에서 상부 구조물의 기초공사 중 파일항타 작업은 필수적인 공사이다. 파일의 품질향상과 장비의 발달로 기본요건만 충족시키면 항타 작업의 불량율은 매우 낮아진다. 즉 장비의 안정된 수평작업의 자세와 정밀측량에 의해 정확한 작업위치가 선행되면 우량공사를 수행할 수 있다.In the construction work, pile driving work is essential during the foundation work of superstructure. If the basic requirements are satisfied by the improvement of pile quality and the development of equipment, the failure rate of driving work is very low. That is, if the correct working position is preceded by the attitude and precision survey of stable horizontal work of the equipment, it is possible to perform the fine work.

일반적인 항타작업의 측정 방식은 관입심도의 측정은 줄자로 재 거나 아예 생략을 하고, 기록을 하는 경우에도 전담자를 두어 수기작업을 한다.In general, the measurement method of the piercing operation is to measure the penetration depth with a tape measure or omit altogether.

당연히 정확도를 판단하거나 작업의 충실도를 검증할 방법이 없다.Naturally, there is no way to judge accuracy or verify the fidelity of a task.

간간이 자동 측정 및 기록의 방법이 시도되었지만 항타시의 엄청난 충격과 진동의 영향을 소거시키지 못하여 실용화가 안 됐다. Although a method of automatic measurement and recording has been attempted at times, it has not been put to practical use because it does not eliminate the impact of tremendous shock and vibration during driving.

항타시의 충격과 소음, 그리고 진동의 영향을 없애기는 아주 어렵다.It is very difficult to eliminate the effects of shock, noise and vibration during driving.

반복해서 충격과 변위가 발생하여 지중으로 관입되는 파일의 변위를 측정하는 것은 측정 센사나 측정장치의 설치가 어렵다.It is difficult to install a measuring sensor or measuring device to repeatedly measure the displacement of pile piles into the ground due to impact and displacement.

지진계의 기록 장치 중 상하 방향의 진동을 기록하는 장치의 원리를 이용하여 진동에 의한 파일 변위의 오차를 보정할 수 있도록 파일 변위 측정 장치 자체의 변위를 측정하는 장치이다.It is a device that measures the displacement of the pile displacement measuring device itself so as to correct an error of pile displacement due to vibration by using the principle of the apparatus for recording the vibration in the up and down direction of the recording device of the seismograph.

건설공사 중 상부 구조물의 기초공사를 위해 파일을 땅속으로 박는 파일항타 작업에서, 파일의 변위를 감지하기 위한 최종 관입 시험 측정 장치 중 파일의 변위를 측정하는 변위 측정 센사의 변위를 측정하는 파일 변위 측정 센사의 변위 측정기의 발명이다.In the pile driving work to pile the pile into the ground for the foundation work of the superstructure during construction, the pile displacement measurement to measure the displacement of the displacement measuring sensor to measure the displacement of the pile in the final penetration test to detect the displacement of the pile. Sensa's displacement meter is the invention.

파일항타 작업은, 파일 항타기(A)의 리다(D)에 장치된 가이드 레일에 지지되어 상부에서 하부로 자유낙하하는 망치로, 파일을 타격하여 파일을 땅 속으로 박아 넣는 작업으로써, 타격횟수와 매 타격 마다의 관입길이 및 반동길이등의 자료가 있어 야 공사의 품질을 가늠할 수가 있다.The pile driving work is a hammer that is supported by the guide rail installed in the lid (D) of the pile driving machine (A) and falls freely from the top to the bottom. Data such as penetration length and recoil length for each strike can be used to gauge the quality of construction.

지진계의 기록 장치 중 상하 방향의 진동을 기록하는 장치의 원리를 이용하여 진동에 의한 파일 변위의 오차를 보정할 수 있도록 파일 변위 측정 장치 자체의 변위를 측정하는 장치이다. It is a device that measures the displacement of the pile displacement measuring device itself so as to correct an error of pile displacement due to vibration by using the principle of the apparatus for recording the vibration in the up and down direction of the recording device of the seismograph.

작업 광경은 그림 1과 같이 장비(A)가 붐대로 리다(D)를 차고 있고, 항타기의 램 하우징(H)은 리다에 얹혀서 파일(P)을 두드리고 있다.In the working scene, the equipment (A) is kicked by the boom (D) as shown in Figure 1, and the ram housing (H) of the rider is hitting the pile (P) by placing it on the lid.

그림2는 파일 변위 측정 센사의 변위 측정기의 원리도이다.Fig. 2 shows the principle of displacement measurement of pile displacement sensor.

ㄷ 자형의 받침대(74)의 윗변에서 용수철(72)을 통해 무거운 추(71)를 늘어뜨리고 윗변 또는 아랫변에서 광파 거리 측정기(73)를 설치한다.On the upper side of the c-shaped pedestal 74, the heavy weights 71 hang down through the springs 72, and the light wave distance measuring unit 73 is installed at the upper side or the lower side.

용수철에 달린 추는 관성에 의해 제자리를 지키려하므로 ㄷ 자형의 받침대가 순간적으로 상하의 방향으로 진동을 하여도 움직이지 않는다.The weight attached to the spring tries to keep it in place by the inertia, so the c-shaped pedestal does not move even if it vibrates in the vertical direction.

파일의 항타에 의한 변위를 측정하는 측정기와 같이 설치하면 앞의 측정기의 항타에 의한 지면에 대한 변위를 알 수 있고 그 변위를 알 수 있으면 지면의 흔들림에 의한 항타 중인 파일 변위의 측정오차를 보정 할 수 있게 된다. When installed together with a measuring device that measures the displacement due to the pile drive, it is possible to know the displacement of the ground due to the steering of the previous measuring instrument. It becomes possible.

작업자나 관리자가 작업진행 상황을 정확하게 파악하여 신뢰성 있는 공사를 수행할 수 있으며, 불량시공을 예방할 수 있고, 정밀한 작업과정을 기록으로 남길 수 있다. Workers or managers can accurately grasp the progress of work and carry out reliable construction, prevent construction of defects, and record precise work processes.
