본 발명은 철도 레일의 침하량 측정장치에 관한 것으로서, 특히 철도 레일의 하면부에 철도 레일의 침하를 감지할 수 있는 수단을 설치함으로써 철도 레일의 침하량을 정량적으로 측정할 수 있는 철도 레일의 침하량 측정장치에 관한 것이다.The present invention relates to an apparatus for measuring settlement of railway rails, and in particular, an apparatus for measuring settlement of railway rails that can quantitatively measure the settlement of railway rails by providing a means for detecting settlement of railway rails on a lower surface of a railway rail. It is about.

일반적으로, 철도의 개설 시, 먼저 지반의 다짐 작업을 실시하고, 그 다짐 작업한 상면에 골재층을 적층하며, 그 골재층의 상부에 받침목을 설치한 후 상부에 레일을 설치하게 된다.In general, when the railroad is opened, first, the ground compaction work is performed, and an aggregate layer is laminated on the upper surface of the compacted work, and then a rail is installed on the upper portion of the aggregate layer.

도 1은 종래의 철도 레일의 설치 상태를 보여주는 도면이다. 1 is a view showing an installation state of a conventional railway rail.

도 1에 도시된 바와 같이, 최하부의 연약 지반(110)의 상부에는 토사층(120)이 다짐 작업되고, 상기 토사층(120) 상부에는 골재층(130)이 형성되며, 또한 상기 골재층(130)에는 상부에 받침목(140)이 안착되고, 그 받침목(140)의 상부에는 레일(150)이 고정되는 구조로 구성된다.As shown in FIG. 1, the earth and sand layer 120 is compacted on the lowermost soft ground 110, an aggregate layer 130 is formed on the earth and sand layer 120, and the aggregate layer 130. There is a support neck 140 is seated on the upper portion, and the rail 150 is fixed to the upper portion of the support neck 140 is configured.

이상과 같이, 철도 레일(150)이 연약 지반(110) 등에 설치되는 경우, 장기적인 침하 변형의 문제가 발생되어 받침목(140)과 레일(150)의 들뜸 현상이 발생되는 한편, 그로 인하여 기차 통행시 진동으로 인한 소음이 크게 발생되고, 기차 통행에 의한 흔들림 현상으로 인하여 기차의 통행에 상당한 위험성을 내포하고 있는 경우 가 많아 대형의 인명 사고를 일으키는 원인을 제공하는 문제점을 안고 있다.As described above, when the rail rail 150 is installed in the soft ground 110 or the like, a problem of long-term subsidence deformation occurs and a lifting phenomenon of the support 140 and the rail 150 occurs, thereby causing a train to pass. Noise caused by vibration is greatly generated, and due to the shaking phenomenon caused by train traffic, there are many cases that pose a significant risk in the traffic of a train, which causes a problem of causing a large casualty accident.

이상과 같은 문제에 대한 대책으로 등록실용신안공보 등록번호 제20-0359014호에는 "철도 레일 받침목 침하변형 계측장치"가 제시되고 있다. As a countermeasure against the above problems, "Registration Utility Model Publication No. 20-0359014" suggests a "railroad rail rest settlement measuring device."

도 2는 그와 같은 철도 레일 받침목 침하변형 계측장치가 레일에 설치된 상태를 보여주는 도면이다. 2 is a view showing a state in which such a rail rail support settling strain measurement device is installed on the rail.

도 2에 도시된 바와 같이, 받침목(240)에는 길이방향의 양측면에 각각 기초 말뚝(260)이 연약 지반(210)에 매설되고, 그 기초 말뚝(260)의 상단에는 알루미늄 재질로 제작된 계측관(270)이 결합된다.As shown in FIG. 2, base pegs 260 are buried in the soft ground 210 on both sides of the support 240 in the longitudinal direction, respectively, and an upper end of the base pegs 260 is made of aluminum. 270 is combined.

상기 기초 말뚝(260)과 계측관(270)은 내부가 관통되고 일측이 폐쇄된 부재로, 상기 계측관(270)은, 일측에 눈금(271)이 형성되고, 타측에 관통홀(272)이 형성되어 고정 볼트(273)에 의해 기초 말뚝(260)의 상단에 결합된 상태로 고정된다.The foundation pile 260 and the measurement tube 270 is a member through which the inside penetrates and one side is closed. The measurement tube 270 has a scale 271 formed at one side, and a through hole 272 at the other side. It is formed and fixed to the upper end of the foundation pile 260 by a fixing bolt 273.

상기 받침목(240)에는, 길이방향 양측에 각각 계측 플레이트(275)가 고정 앵 커못(277)으로 고정되어 계측관(270)의 눈금을 지시하도록 되어 있으며, 상기 기초말뚝(260), 계측관(270)과 함께 하나의 계측장치(290)를 구성한다.In the supporting neck 240, the measuring plate 275 is fixed to the fixed angle pin 277 on both sides of the longitudinal direction, respectively, to indicate the scale of the measuring tube 270, the foundation pile 260, measuring tube ( Together with 270, one measuring device 290 is configured.

이상과 같은 종래 계측장치(290)는, 모든 연약 지반(210) 상에 설치된 레일(250)의 침하 변형을 측정할 수 있게 되는데, 작업자들은 수시로 계측관(270)의 눈금(271)을 확인하여 안전 사고를 미연에 방지할 수 있는 사전 조치를 취할 수 있게 된다. 도 2에서 참조번호 220은 토사층, 230은 골재층을 각각 나타낸다.Conventional measuring device 290 as described above, it is possible to measure the settled deformation of the rail 250 installed on all the soft ground 210, the operator checks the scale 271 of the measuring tube 270 from time to time Take precautions to prevent safety accidents. In FIG. 2, reference numeral 220 denotes a soil layer, and 230 denotes an aggregate layer.

그런데, 이상과 같은 종래 계측장치(290)는 계측관(270)의 눈금(271)을 가리키는 계측플레이트(275)가 받침목(240) 상면에 설치되어 있어, 궁극적으로 받침목 (240)의 침하 변형은 측정할 수는 있어도, 철도 레일 자체의 침하량은 측정할 수 없는 문제가 있다. 예를 들면, 받침목(240)을 지지하는 도상이 도 2에 도시된 바와 같이 골재층(230)인 자갈도상이 아니라, 콘크리트 도상인 경우에는, 그리고 더욱이 받침목(240) 자체도 목재가 아닌 콘크리트 제품인 경우에는 받침목(240)의 침하는 거의 일어나지 않게 된다. 그러나, 받침목(240)의 침하가 없다고 하여 레일(250)의 침하도 없는 것으로 볼 수는 없다. 받침목(240)의 침하와 관계없이 레일(250)만의 침하가 얼마든지 존재할 수 있다. 그리고, 이와 같은 레일(250)만의 침하 역시 심각한 철도 사고를 유발할 수 있다. However, in the conventional measuring device 290 as described above, the measuring plate 275 indicating the scale 271 of the measuring tube 270 is installed on the upper surface of the support neck 240, and ultimately, the settlement deformation of the support neck 240 is Although it can measure, there exists a problem that the settlement amount of railway rail itself cannot be measured. For example, if the icon supporting the support 240 is not a gravel layer, which is an aggregate layer 230, as shown in FIG. 2, but is a concrete design, and the support 240 itself is a concrete product, not wood. In this case, the settling of the support 240 rarely occurs. However, just because there is no settlement of the support neck 240 is not considered to be without the settlement of the rail 250. Regardless of the settlement of the support 240, there may be any settlement of the rail 250 only. In addition, such a settlement of the rail 250 may also cause a serious railway accident.

본 발명은 이상과 같은 사항을 감안하여 창출된 것으로서, 철도 레일의 하면부에 철도 레일의 침하를 감지할 수 있는 수단을 설치함으로써 철도 레일의 침하량을 정량적으로 측정할 수 있는 철도 레일의 침하량 측정장치를 제공함에 그 목적이 있다.The present invention has been made in view of the above-mentioned matters, and by installing a means for detecting the settlement of railway rails on the lower surface of the railway rail, the settlement amount measurement of the railway rail capable of quantitatively measuring the settlement of the railway rail The purpose is to provide.
