옹벽(50)에는 다수개의 측정판(60)(60')이 설치되되, 측정판(60)은 옹벽(50)의 길이를 따라 상면 양측에 설치되는 대형(大形)의 측정판이 사용됨과 아울러 다른 측정판(60')은 대형의 측정판(60)이 설치된 사이에 설치되는 다수개의 소형(小形)의 측정판이 있으며, 측정판(60)에는 기준선(61)에 인접하여 3개의 안착홀(62)과 사각홈(63)이 형성된다.The retaining wall 50 is provided with a plurality of measuring plates 60 and 60 ', and the measuring plate 60 uses a large measuring plate installed on both sides of the upper surface along the length of the retaining wall 50. The other measuring plate 60 'has a plurality of small measuring plates which are installed between the large measuring plate 60, and the measuring plate 60 has three seating holes adjacent to the reference line 61. 62 and the square groove 63 is formed.

또한, 측정판(60)에는 길이 양측에 체결홀(64)이 형성되어 지지봉(66)이 결합되어 스프링(67)으로 옹벽(50) 상면에 고정지지되게 되며, 다른 측정판(60')은 옹벽(50) 상면에 체결못을 통해 고정하게 된다.In addition, the measuring plate 60 is fastening holes 64 are formed on both sides of the length of the support rod 66 is coupled to be fixed to the upper surface of the retaining wall 50 by the spring 67, the other measuring plate 60 ' The retaining wall 50 is fixed through a fastening nail.

지지봉(66)은 대략 ㅁ자 형태를 유지하되, 일측이 절개된 형상이고, 측정판(60)에는 측면에 스프링 연결봉(65)이 형성되어 스프링(67)의 힘이 옹벽 측으로 전해지게 되며, 스테인레스 봉을 이용하여 제작하게 된다.The support rod 66 maintains a substantially K-shaped shape, but one side is cut in shape, and a spring connecting rod 65 is formed at the side of the measuring plate 60 so that the force of the spring 67 is transmitted to the retaining wall. It will be produced using.

측정판(60)에는 상면에 경위의(20)가 안착되되, 경위의(20)는 안착홀(62)에 다리가 삽입고정되며, 경위의(20)는 측정판(60)의 + 표기 상면에 위치된다.Theodolite 20 is seated on the upper surface of the measuring plate 60, but theodolite 20 is fixed with a leg inserted into the seating hole 62, and theodolite 20 is a + marking upper surface of the measuring plate 60. Is located in.

옹벽(50) 상면 길이방향 양측에 설치되는 측정판(60)에는 사각홈(63)에 송,수신 센서(S)(P)가 위치되어 와이어(W)에 의해 전원을 인가하는 밧데리(B)에 연결되되, 송신 센서(S)에는 전면에 +표기가 되어 있고 그 +표기에 경위의(20)의 십자(+) 교차점이 일치된다.In the measuring plate 60 installed on both sides of the retaining wall 50 in the longitudinal direction, the transmitting and receiving sensors S and P are located in the square groove 63, and the battery B is applied to the power by the wire W. It is connected to the transmission sensor (S) has a + notation on the front and the + notation coincides with the cross (+) intersection of theodolite 20.

즉, 일측 측정판(60) 상면에 안착된 경위의(20)와 수신 센서(P)는 타측 측정판(60) 상면에 안착된 송신 센서(S)에 상호 연계작동하게 되어 위치가 이탈되면 경위의(20)와 수신 센서(P)에서 그 위치 이탈을 손쉽게 측정할 수 있게 된다.That is, theodolite 20 and the receiving sensor P seated on the upper surface of one measuring plate 60 are mutually linked to the transmitting sensor S seated on the upper surface of the other measuring plate 60 so that the position is separated. It is possible to easily measure the position deviation from the (20) and the receiving sensor (P).

이는 송,수신 센서(S)(P)가 상호 마주보도록 설치되어 있는 관계로 송,수신 센서(S)(P)의 어느 하나가 위치 이탈하게 되면 밧데리(B)와 연결된 경광등(90)이 빛을 발하게 되게 된다.This is because the transmission and reception sensor (S) (P) is installed to face each other, when one of the transmission and reception sensor (S) (P) is out of position, the warning light (90) connected to the battery (B) is light Will be released.

또한, 경위의(20)는 송신 센서(S)의 +표기된 교차점과 일치되어 있어 경위의(20)를 통해 육안으로 확인하여 교차점이 이탈되면 전도량을 알 수 있게 된다.In addition, theodolite 20 is coincident with the + marked intersection point of the transmission sensor S, so that the conduction amount can be known when the intersection point deviates from the naked eye through the theodolite 20.

상술한 옹벽(50)의 전도량 측량시설의 설치상태를 설명한다.The installation state of the conductivity measurement facility of the retaining wall 50 will be described.

먼저, 옹벽(50)에는 상면에 + 표기와 - 표기가 일치되도록 다수개의 측정판(60)(60')이 안착된다.First, a plurality of measuring plates 60 and 60 'are mounted on the retaining wall 50 so that + and-markings coincide with each other.

이때 옹벽(50) 상면에 안착된 측정판(60)과 다른 측정판(60')은 기준선(61)을 일치시킨다.At this time, the measuring plate 60 and the other measuring plate 60 'seated on the retaining wall 50 upper surface coincide with the reference line 61.

다음으로, 측정판(60)의 사각홈(63)에 송,수신 센서(S)(P)를 안착한다.Next, the transmission and reception sensor (S) (P) is seated in the square groove (63) of the measuring plate (60).

이때, 송,수신 센서(S)(P)는 전원을 인가하는 밧데리(B)에 연결함은 물론, 일측 측정판(60)에 경위의(20)를 안착하여 최초 위치를 설정하게 된다.At this time, the transmission and reception sensor (S) (P) is connected to the battery (B) to apply power, as well as to set the initial position by seating theodolite 20 on one measuring plate 60.

다음으로, 밧데리(B)에 경광등(90)을 연결한다.Next, the warning lamp 90 is connected to the battery (B).

이때, 송,수신 센서(S)(P)가 위치 이탈되게 되면 경광등(90)이 발광할 뿐만 아니라 경위의(20)를 읽어 오차 눈금을 읽게 된다.At this time, when the transmission and reception sensor (S) (P) is out of position, the warning lamp 90 not only emits light, but also reads the theodolite 20 to read the error scale.
