Abstract

A pile measuring apparatus in shock-free condition and a batch-type recording method are provided to measure and record accurately by preventing damage from vibration and shocks and mixture of unnecessary data. A pile measuring apparatus in shock-free condition includes a pile frame(15), a slope sensor(16), a hydraulic cylinder(17), a contact sensor(14), an automatic reel(11), a measuring line(12), and a length sensor(13). The pile frame is accurately attached at the outer circumference of a pile. The slope sensor is fixed at the pile frame. The hydraulic cylinder attaches/detaches the pile frame at/from the pile. The contact sensor is installed at the inner surface which is in contact with the external surface of the pile. The automatic reel is automatically reeled. The measuring line measures the length of entrance of the pile. The length sensor senses the length of the measuring line reeled according to the rotation of the automatic reel.

P 파일 10 측정장치P pile 10 measuring device

건설 현장에서 파일의 항타작업을 할 때의 작업과정 중 파일의 기울기와 관입 길이 및 항타수 등을 자동으로 측정하여 기록하되, 햄머로 파일을 가격하여 파일이 진동하는 순간은 피하여, 무진동의 상태에서 측정을 하는 장치와, 그 장치를 이용하여 싸이클 별로 측정된 데이타를 조합하여 기록하는 뱃치식 기록 방법에 관한 발명이다.Automatically measures and records the pile's inclination, penetration length, and number of strokes during the driving process of the pile at the construction site, but avoids the moment when the pile vibrates by hitting the pile with a hammer. The invention relates to a batch recording method for recording a combination of a measurement device and data measured for each cycle using the device.

일반적인 항타작업의 측정과 기록 방식은 트랜시트나 실에 매달린 추를 보고 수직도를 판단하고 관입심도의 측정은 줄자로 재 거나 아예 생략을 하고, 기록을 하는 경우에도 전담자를 두어 수기작업을 한다.In general, the method of measuring and recording the rudder work is to determine the verticality by looking at the weight suspended from the transit or the thread. The measurement of the penetration depth is measured with a tape measure or skipped 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, 연속적인 측정과 기록을 추구한 결과로 항타시의 엄청난 충격과 진동의 영향을 소거시키지 못하여 실용화가 안 됐다. Although a method of automatic measurement and recording has been attempted at times, the pursuit of continuous measurement and recording has not been practical because it has not eliminated 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.

그러나 파일의 모든 변위는 항타하는 순간에만 발생하고 또한 충격과 진동도 항타하는 순간부터 잠간 동안에 소거된다는 점에 착안하고, 단속적인 측정과 기록이라도 작업과정을 확인하고 기록하는데 아무 하자가 없다면 전항의 문제점을 해결하는 것은 간단해 진다.However, paying attention to the fact that all displacements of the pile occur only at the moment of driving and are also erased for a while from the moment of impact and vibration. Solving is simplified.

고요한 시간 즉 햄머가 타격준비를 위해 상승하는 시간 중에 측정과 기록을 수행하는 것이다.  Measurements and recordings are performed during a quiet time, ie as the hammer rises to prepare for hitting.

건설 현장에서 파일의 항타작업을 할 때의 작업과정 중 파일의 기울기와 관입 길이 및 항타수 등을 자동으로 측정하여 기록하되, 햄머로 파일을 가격하여 파일이 진동하는 순간은 피하여, 무진동의 상태에서 측정을 하는 장치와, 그 장치를 이용하여 싸이클 별로 측정된 데이타를 조합하여 기록하는 뱃치식 기록 방법에 관 한 발명이다.Automatically measures and records the pile's inclination, penetration length, and number of strokes during the driving process of the pile at the construction site, but avoids the moment when the pile vibrates by hitting the pile with a hammer. The invention relates to a batch recording method for recording a combination of a measurement device and data measured for each cycle using the device.

진동과 충격이 큰 독립적인 작업의 조합을 연속으로 측정하고 기록하는 대신, 짬짬이 무진동인 시간에 작업 싸이클 별로 측정과 기록을 하여 조합을 함으로써, 연속으로 측정하고 기록하는 과정에서의 진동과 충격에 의한 측정기기들의 손상과, 불필요한 데이타의 혼입이 방지되어, 정확한 측정과 기록이 가능하고 측정기기들의 유지 관리와 작업 결과의 판독이 수월하다. Instead of continuously measuring and recording a combination of independent tasks with high vibration and shock, instead of measuring and recording each work cycle at a time when vibration is non-vibration, the combination is performed. Damage to the measuring instruments and the incorporation of unnecessary data are prevented, enabling accurate measurement and recording, and easy maintenance of the measuring instruments and reading of the work results.

작업 광경은 그림 1과 같이 장비(A)가 붐대(B)로 리다(D)를 차고 있고, 항타기(H)는 리다에 얹혀서 파일(P)을 두드리고 있다.As seen in Figure 1, the equipment (A) is kicked with the boom (B) and the rider (H) is hitting the pile (P) as shown in Figure 1.

무진동 항타 측정장치(10)는 장비의 전면 하부의 리다의 뒤쪽에 위치하는 것이 작업에 방해가 되지 않는다.The vibration-free driving measuring device 10 is located in the rear of the rear of the front lower portion of the equipment does not interfere with the operation.

무진동 항타 측정장치는, 파일의 외주면에 정확히 밀착하는 형상의 파일 형틀(15)과 그 파일 형틀에 고착된 기울기 감지 센사(16), 파일 형틀을 파일에서 붙였다 떼었다 해주는 유압 실린다(17)로 이루어진 기울기 감지장치와, 자동으로 감기는 자동릴(11)과 파일의 관입길이를 측정하기 위해서 항타기에서 자동릴로 연결된 측정선(12), 자동릴의 회전에 따라 감기는 측정선의 길이를 감지하는 길이 감지센사(13)로 이루어진 관입량 감지 장치로 구성된다.  The vibration-free measuring device is composed of a pile form 15 of a shape that closely adheres to the outer circumferential surface of a pile, a tilt sensing sensor 16 attached to the pile form, and a hydraulic seal 17 that attaches and detaches a pile form from a pile. A tilt detection device, an automatic reel 11 which is automatically wound, and a measuring line 12 connected to an automatic reel in a navigator to measure the penetration length of the pile, and a length detection which detects the length of the measuring line wound by the rotation of the automatic reel. It is composed of a penetration detection device consisting of the sensor (13).

파일형틀(15)의 파일의 외면과 맞닿는 내면에는 접촉센사(14)가 장치되어 기울기 감지장치와 파일의 접촉여부의 신호 및 항타 횟수를 세는 신호로 콘트롤라에 입력되고, 관입되는 길이보다 튀는길이, 즉 반동되는 길이가 더 클 때는 자동릴(11)에서 측정선이 풀려나가게 되고 측정선이 풀려나가면 길이 감지센사는 부(-)의 값을 나타내는데 이값은 리바운드의 값이 된다.. A contact sensor 14 is provided on the inner surface of the pile frame 15 in contact with the outer surface of the pile, and is input to the controller as a signal for counting whether the tilt detection device is in contact with the pile and the number of strokes. That is, when the recoil length is larger, the measuring line is released from the automatic reel 11, and when the measuring line is released, the length sensing sensor indicates a negative value, which becomes a rebound value.

기울기 감지장치의 유압 실린다는 항타기의 햄머를 낙하시키는 신호에 연동되어 항타기가 파일을 항타한 직후, 즉 항타의 충격과 진동이 가신 다음에 파일 형틀이 파일에 접촉되도록, 도시되지 않은 콘트롤라로 부터 자동제어가 된다. The hydraulic loading of the tilt detection device is linked to a signal that drops the hammer of the helm, so that the file form contacts the file immediately after the helm hits the file, i.e. after the shock and vibration of the helm have passed, the controller is not shown. Control.

또한 관입량 감지장치의 자동릴은 항타 직후에 늘어진 측정선을 항타 후에 감아들이고 그 감아 들인 결과를 길이 감지센사가 감지하기 때문에 기울기 감지장치와 마찬가지로 무진동, 무충격 상태에서 파일의 변위를 측정한다. In addition, the automatic reel of the penetration detection device winds up the measuring line immediately after the stroke, and detects the result of the winding.

위에 설명한 무진동 항타 측정장치를 이용한 항타 기록 방법을 순서대로 설명한다. The driving recording method using the vibration-free driving measuring device described above will be described in order.

진동과 충격이 큰 독립적인 작업의 조합을 연속으로 측정하고 기록하는 대신, 짬짬이 무진동인 시간에 작업 싸이클 별로 측정과 기록을 하여 조합을 함으로써, 연속으로 측정하고 기록하는 과정에서의 진동과 충격에 의한 측정기기들의 손상과, 불필요한 데이타의 혼입이 방지되어, 정확한 측정과 기록이 가능하고 측정기기들의 유지 관리와 작업 결과의 판독이 수월하다. Instead of continuously measuring and recording a combination of independent tasks with high vibration and shock, instead of measuring and recording each work cycle at a time when vibration is non-vibration, the combination is performed. Damage to the measuring instruments and the incorporation of unnecessary data are prevented, enabling accurate measurement and recording, and easy maintenance of the measuring instruments and reading of the work results.
