（１）本発明の全体の構成
本発明に係る沈下測定装置は、構造物の変位を測定するためのものである。
本発明の沈下測定装置は、基準水槽１と、複数の沈下計２、基準水槽１と複数の沈下計２間を連結する連通管３、及び複数の沈下計２と連通管３とを内部に収容する外殻４からなる。また、外殻４内部には緩衝流体５を注入する。（図１）
基準水槽１、沈下計２、連通管３の内部には測定水６が封入されている。
外殻４の一方の端部と他方の端部とは外部配管７によって連結する。外部配管７の一部には搬送機８を設ける。
以下、各構成部材について説明する。 (1) Overall Configuration of the Present Invention A settlement measurement apparatus according to the present invention is for measuring the displacement of a structure.
The settlement measuring device of the present invention includes a reference water tank 1, a plurality of settlement meters 2, a communication pipe 3 connecting the reference water tank 1 and the plurality of settlement gauges 2, and a plurality of settlement gauges 2 and the communication pipe 3 inside. It comprises an outer shell 4 to be accommodated. A buffer fluid 5 is injected into the outer shell 4. (Figure 1)
Measurement water 6 is sealed inside the reference water tank 1, the settlement meter 2, and the communication pipe 3.
One end of the outer shell 4 and the other end are connected by an external pipe 7. A conveyor 8 is provided in a part of the external pipe 7.
Hereinafter, each component will be described.

（２）基準水槽
基準水槽１は、連通管３によって連結する沈下計２の水圧や水位を一定にするためのものである。
基準水槽１は、基準部水槽１１と回収補給槽１２の２槽からなる。基準水槽１の内部には測定水６が封入されている。（図１）
基準部水槽１１と回収補給槽１２との間は、所定の高さの堰１３によって仕切られている。 (2) Reference water tank The reference water tank 1 is for making the water pressure and water level of the settlement meter 2 connected by the communication pipe 3 constant.
The reference water tank 1 is composed of two tanks, a reference part water tank 11 and a recovery supply tank 12. Measurement water 6 is sealed inside the reference water tank 1. (Figure 1)
The reference portion water tank 11 and the collection and replenishment tank 12 are partitioned by a weir 13 having a predetermined height.

基準部水槽１１には、回収補給槽１２から給水ポンプ１４によって常に測定水６が供給されている。
基準部水槽１１に供給された測定水６は、堰１３を越えて溢れると再び回収補給槽１２に流れ込んで循環している。これによって、基準部水槽１１の水面は常に堰１３の高さと同一のレベルに保たれている。
基準部水槽１１には水面下で連通管３を接続し、連通管３の他方の端部は、沈下計２に接続する。
基準水槽１は沈下測定装置の基準の水位となるものであるため、高さの変動が生じない場所に設置する。 The reference water tank 11 is always supplied with the measurement water 6 from the collection and replenishment tank 12 by the water supply pump 14.
When the measurement water 6 supplied to the reference section water tank 11 overflows over the weir 13, it flows again into the recovery supply tank 12 and circulates. Thus, the water surface of the reference section water tank 11 is always kept at the same level as the height of the weir 13.
The communication pipe 3 is connected to the reference portion water tank 11 under the water surface, and the other end of the communication pipe 3 is connected to the settlement meter 2.
Since the reference water tank 1 serves as a reference water level for the settlement measurement apparatus, it is installed in a place where the height does not vary.

（３）沈下計
沈下計２は構造物９の変位を測定する位置に配置し、内部の測定水６の圧力差や水位差により、測定位置の沈下量を求めるためのものである。
沈下計２には、例えばベローズと差動トランスで構成され、水圧の変動によるベローズの変形によって差動トランスのコアが移動し、コイルとの間の相対変位に比例して発生する電圧を変換して沈下量を得る装置を用いる。 (3) Subsidence meter The subsidence meter 2 is disposed at a position where the displacement of the structure 9 is measured, and is used to determine the amount of subsidence at the measurement position based on the pressure difference or water level difference of the internal measurement water 6.
The settlement meter 2 is composed of, for example, a bellows and a differential transformer, and the core of the differential transformer moves due to deformation of the bellows due to fluctuations in water pressure, and converts the voltage generated in proportion to the relative displacement between the coils. Use a device to obtain the amount of settlement.

沈下計２は構造物のうち変位を測定したい複数の任意の場所に設置する。
沈下計２は固定具２１を介して構造物９に取り付ける。（図２）
隣接する沈下計２間は連通管３によって連結する。沈下計２のうち少なくとも一つは、連通管３によって基準水槽１と連結する。
連通管３は、沈下計２が構造物の変位に追従して移動できるように、合成樹脂等の可撓性を有する材料からなる。 The subsidence meter 2 is installed in a plurality of arbitrary locations where displacement is to be measured.
The settlement meter 2 is attached to the structure 9 via the fixture 21. (Figure 2)
Adjacent settlement meters 2 are connected by a communication pipe 3. At least one of the subsidence meters 2 is connected to the reference water tank 1 by a communication pipe 3.
The communication pipe 3 is made of a flexible material such as synthetic resin so that the settlement meter 2 can move following the displacement of the structure.

（３）外殻
外殻４は沈下計２と、連通管３と、沈下計２と連通管３を包囲する緩衝流体５を内包するものである。
外殻４はプラスチックや塩ビ等の合成樹脂からなり、内部に収容する緩衝流体５が漏洩しない構成とする。
外殻４は上部を開放した形状とし、固定具２１を介して構造物９に取り付けた沈下計２を上部から導入して内包する。（図２） (3) Outer shell The outer shell 4 contains the settlement meter 2, the communication pipe 3, and the buffer fluid 5 surrounding the settlement meter 2 and the communication pipe 3.
The outer shell 4 is made of a synthetic resin such as plastic or vinyl chloride, and is configured such that the buffer fluid 5 accommodated therein does not leak.
The outer shell 4 is shaped so that the upper part is open, and the settlement meter 2 attached to the structure 9 via the fixture 21 is introduced from the upper part and included. (Figure 2)

（４）緩衝流体
緩衝流体５は外殻４内において沈下計２と連通管３とを包囲する流体である。
緩衝流体５には、空気や水を用いることができる。
外殻４内の沈下計２と連通管３とが、緩衝流体５によって包囲されるため、外殻４の外側の気温の変化が緩衝流体５によって遮断されることとなる。このため沈下計２や連通管３内部の測定水６が、外殻４の外側の気温の変化の影響を受けずに、一定の温度に保たれる。 (4) Buffer Fluid The buffer fluid 5 is a fluid that surrounds the settlement meter 2 and the communication pipe 3 in the outer shell 4.
The buffer fluid 5 can be air or water.
Since the settlement meter 2 and the communication pipe 3 in the outer shell 4 are surrounded by the buffer fluid 5, changes in the temperature outside the outer shell 4 are blocked by the buffer fluid 5. For this reason, the measured water 6 inside the settlement meter 2 and the communication pipe 3 is kept at a constant temperature without being affected by the change in the temperature outside the outer shell 4.

（５）外部配管
外部配管７は、外殻４の一方の端部と他方の端部とを外部配管７によって連結し、緩衝流体５の流路となるものである。
外部配管７の一部には搬送機８を設ける。搬送機８は、緩衝流体５に合わせて、緩衝流体５が水の場合にはポンプを、空気の場合にはファンを使用する。
搬送機８から吐出した緩衝流体５は、外部配管７を通って外殻４の一方の端部から外殻４内へ入り、外殻４内部を通過して他方の端部から外部配管７へと循環される。
また、外部配管７にはクーラーやヒーター等の温度調節器を設けてもよい。 (5) External piping The external piping 7 connects one end portion of the outer shell 4 and the other end portion by the external piping 7 and serves as a flow path for the buffer fluid 5.
A conveyor 8 is provided in a part of the external pipe 7. The carrier 8 uses a pump when the buffer fluid 5 is water and a fan when the buffer fluid 5 is air, in accordance with the buffer fluid 5.
The buffer fluid 5 discharged from the carrier 8 enters the outer shell 4 from one end of the outer shell 4 through the outer pipe 7, passes through the outer shell 4 and enters the outer pipe 7 from the other end. And cycled.
Further, the external pipe 7 may be provided with a temperature controller such as a cooler or a heater.

［測定方法］
次に、上記のように構成した沈下測定装置を用いて構造物の変位を測定する方法について説明する。 [Measuring method]
Next, a method for measuring the displacement of the structure using the settlement measuring apparatus configured as described above will be described.

構造物のうち、変位を測定する場所に跨って外殻４を配置する。
次に、固定具によって構造物９に取り付けた沈下計２と、連通管３とを接続し、外殻４内部に挿入する。
その後、基準水槽１を設置し、外殻４から延出した連通管３に接続し、測定水６を各装置内部に注入する。
そして、外殻４内に緩衝流体５を注入し、内部に収容した沈下計２と連通管３を緩衝流体５によって包囲する。 Out of the structure, the outer shell 4 is disposed across the place where the displacement is measured.
Next, the settlement meter 2 attached to the structure 9 with the fixture and the communication pipe 3 are connected and inserted into the outer shell 4.
Thereafter, the reference water tank 1 is installed, connected to the communication pipe 3 extending from the outer shell 4, and the measurement water 6 is injected into each apparatus.
Then, a buffer fluid 5 is injected into the outer shell 4, and the settlement meter 2 and the communication pipe 3 housed inside are surrounded by the buffer fluid 5.

構造物９のうち、沈下計２の設置場所の高さに変位が生じると、基準水槽１との相対高さに変位が生じる。
沈下計２は固定具２１を介して構造物９に取り付けられているため、構造物９の高さの変位が直に沈下計２に伝わる。
基準水槽１と沈下計２とは連通管３で連結されており、内部の測定水６も一体となっている。このため沈下計２の高さの変位に合わせて、沈下計２内部の水位や水圧が変化する。
この変化によって、基準水槽１に対する測定場所の変化量を計測することができる。 In the structure 9, when a displacement occurs in the height of the installation place of the settlement meter 2, a displacement occurs in a relative height with respect to the reference water tank 1.
Since the settlement meter 2 is attached to the structure 9 via the fixture 21, the displacement of the height of the structure 9 is directly transmitted to the settlement meter 2.
The reference water tank 1 and the settlement meter 2 are connected by a communication pipe 3, and the internal measurement water 6 is also integrated. For this reason, according to the displacement of the height of the squat meter 2, the water level and water pressure inside the squat meter 2 change.
By this change, the change amount of the measurement place with respect to the reference water tank 1 can be measured.

基準水槽１が高さの変動が生じてしまう場所に設置される場合には、沈下計２のいずれか一つを基準沈下計２ａとして、高さの変動が生じない不動点に配置する。
基準沈下計２ａの測定値と、その他の沈下計２の測定値との差によって、不動点に対するその他沈下計２の設置場所の変位量を計測することができる。 When the reference water tank 1 is installed in a place where the fluctuation of the height occurs, any one of the subsidence meters 2 is set as a reference subsidence meter 2a at a fixed point where the fluctuation of the height does not occur.
Based on the difference between the measured value of the reference squat meter 2a and the measured value of the other squat meter 2, the amount of displacement of the installation site of the other squat meter 2 relative to the fixed point can be measured.

測定中に、沈下計２と連通管３内部の測定水６に温度変化や温度むらが生じると、測定水６の密度が変化し、沈下計２での測定値に誤差が生じてしまう。
しかし、本発明の沈下測定装置は沈下計２と連通管３とを包囲する緩衝流体５によって、外気温の変化が緩和又は遮断されることとなる。
これによって、測定水６の温度が一定に保たれるため、温度変化による誤差が生じることがない。 During the measurement, if temperature change or temperature unevenness occurs in the measurement water 6 inside the subsidometer 2 and the communication pipe 3, the density of the measurement water 6 changes and an error occurs in the measurement value in the subsidometer 2.
However, in the settlement measuring device of the present invention, the change in the outside air temperature is alleviated or blocked by the buffer fluid 5 surrounding the settlement meter 2 and the communication pipe 3.
As a result, the temperature of the measurement water 6 is kept constant, so that an error due to a temperature change does not occur.

緩衝流体５には、空気や水が用いられる。
空気や水は安価で安全なものである。このため、安全かつ安価に、温度変化による誤差が生じない沈下測定装置を作ることができる。 Air or water is used as the buffer fluid 5.
Air and water are cheap and safe. For this reason, it is possible to make a settlement measuring device that is safe and inexpensive and does not cause an error due to a temperature change.

緩衝流体５は搬送機８によって、外殻４と外部配管７内部を循環する。
循環することによって、外殻４内の緩衝流体５の温度むらが無くなり、沈下計２および連通管３の内部の測定水６もより均一な温度に保たれる。
また、温度調節器９によって外気温度に合わせて、緩衝流体５の温度も一定に調節されるため、緩衝流体５の緩和又は遮断効果が増し、沈下計２および連通管３の内部の測定水６もより均一な温度に保たれる。 The buffer fluid 5 circulates inside the outer shell 4 and the external pipe 7 by the transporter 8.
By circulating, the temperature unevenness of the buffer fluid 5 in the outer shell 4 is eliminated, and the settlement water 2 and the measured water 6 inside the communication pipe 3 are also kept at a more uniform temperature.
In addition, since the temperature of the buffer fluid 5 is also adjusted to be constant according to the outside air temperature by the temperature controller 9, the relaxation or blocking effect of the buffer fluid 5 is increased, and the measured water 6 inside the settlement meter 2 and the communication pipe 3 is increased. Is maintained at a more uniform temperature.

また、上記において、外殻４はプラスチックや塩ビ等の合成樹脂からなる部材を使用したが、外殻４として、測定対象である構造物そのものを利用してもよい。（図５）
例えば、構造物のうち変位を測定する場所に跨って溝を構築し、その内部に沈下計２および連通管３を配置し、溝に緩衝流体５となる水を流し込み、沈下計２および連通管３を沈水する。
このように構成することにより、外殻４を使用せずに、温度変化による誤差が生じない沈下測定装置を作ることができる。 In the above description, the outer shell 4 is a member made of a synthetic resin such as plastic or vinyl chloride. However, the outer shell 4 may be a structure to be measured. (Fig. 5)
For example, a groove is constructed across the location where displacement is to be measured in the structure, and a settlement meter 2 and a communication pipe 3 are arranged in the interior, and water that serves as a buffer fluid 5 is poured into the groove. 3 is submerged.
By comprising in this way, the subsidence measuring apparatus which does not produce the error by a temperature change without using the outer shell 4 can be made.
