以下、この発明について実施例を上げ、詳細に説明する
。Hereinafter, the present invention will be described in detail using examples.
作業を開始するに際しては、先ず初期検査が行なわれる
。この初期検査には管路の漏れ検査、スケールによる閉
塞度検査が必要である。Before starting work, an initial inspection is performed. This initial inspection requires a leak test of the pipeline and a blockage test using a scale.
漏れ検査は被清浄管路の端部を密閉し、封入流体圧の圧
力降下を見る。For leak testing, the end of the pipeline to be cleaned is sealed and the pressure drop in the sealed fluid pressure is observed.

りＣＲＴにその画表示する。FIG. 3 shows the control flow diagram when testing pressure drop. The inspection is started in step 101, and step 10
2. Enter the pressure sensor value. In step 103, the test is performed at an appropriate pressure by comparing it with a standard pressure value previously input into the memory. For example, the degree of pressure drop can be determined using the initial value of the pressure sensor itself as a standard. The measured values are plotted on a graph on the CRT 19 (step 104). It is preferable to temporarily store the pressure value at this time in the memory (step 105). In step 106, if the measured value of the pressure sensor is significantly lower than the standard value (for example, the initial value), the process immediately moves to step 169 and displays the image on the CRT.
この場合、その圧力値はＣＲＴ上に表わされているので
どの程度の漏れが生じているのかは明白である。In this case, since the pressure value is displayed on the CRT, it is clear how much leakage is occurring.
ステップ１０６で漏れは全く無いか、或いは余り大きく

ップ１０７で、例えば所定の検査時間が経ったか否かが
判断され、測定続行の場合にはステップ１０８に移る。If it is determined in step 106 that there is no leakage at all or that it is not very large, the process moves to step 107. In step 107, it is determined whether or not, for example, a predetermined inspection time has elapsed, and if the measurement is to be continued, the process moves to step 108.
漏れ測定は比較的長時間を要し、必ずしも連続した測定

従って、例えば１０秒毎に測定を行なうべくステップ１
０８で時間待ちをし、ステップ１０２に返るのである。Therefore, for example, in order to take measurements every 10 seconds, step 1
At step 08, the process waits for a certain amount of time and returns to step 102.

出づことができる。According to this embodiment, the leakage test can not only be carried out automatically, but also its contents can be displayed in the form of a graph on the CRT. Therefore, it can be taken out onto recording paper or the like as desired.
次いで、初期検査では密閉度検査を行なう。Next, in the initial inspection, a tightness inspection is performed.

へラダ２３側から開放端側へ流れ、圧力勾配を生ずる。FIG. 4 shows an overview of the airtightness inspection, in which a header 23 is attached to one end, a pressure lens 1) S is provided on the header 23, and a pipe 25 for supplying fluid such as air or water is connected to the header 23. The length of the pipeline to be cleaned σ] The other end is open. The fluid flows from the spatula 23 side to the open end side, creating a pressure gradient.
開放端の圧力ｉよ大気圧ｐａであり、圧力センサの測定
圧力をＰとづる。The pressure i at the open end is equal to the atmospheric pressure pa, and the pressure measured by the pressure sensor is denoted as P.
上記構成により、管路の閉塞度をめる一例を示す。An example of increasing the degree of blockage of the conduit with the above configuration will be shown.
管路に流体を通す場合、総損失Ｈをめる公式は、直管の
摩擦損失係数をλｏ１管の内径をｄｏ。When passing fluid through a pipe, the formula for calculating the total loss H is: λo1 is the friction loss coefficient of a straight pipe, and do is the inner diameter of the pipe.

ここに損失水頭は圧力差Ｐ−Ｐａに相当する。Here, the head loss corresponds to the pressure difference P-Pa.
そこで、例えば流量を一定とし、被清ｒｐ管の摩擦損失

してまる。Therefore, for example, if the flow rate is constant, the friction loss coefficient of the RP pipe to be cleaned is assumed to be 220, and the estimated pipe diameter of the pipe to be cleaned is set to d1 loss head of 1-1, then the following equation is obtained. Therefore, if we ignore Σζ+1, (d/do)

---■ Therefore, if the head loss Ha of the new pipe (inner diameter do) is expressed by the formula (■) and the pressure gradient (P-F'a) is modeled on the head pressure, rj1 blockage X is x = d/d'o = (2-1-1o /I-1>”).

きるものである。The above calculation formula is only an example, and it is also possible to provide two pressure sensors in the middle of the conduit and determine the degree of occlusion X from the pressure difference. Further, the present invention is not limited to water flow, and can be applied to any fluid with appropriate correction.

The gradient determining means 27 determines the degree of occlusion X from this comparison result and displays it on the CRT 19.

測定完了する。FIG. 5 shows a control flowchart for determining the pressure gradient. Starting in step 2C)1, a pressure value P is read in step 202. Atmospheric pressure Pa1 in step 203
The degree of occlusion X can be determined from the relationship with the length of the tube, the tube diameter d, etc. as described above. When it is difficult to determine the pipe length, pipe diameter d, etc. for structural piping, etc., set a standard value for comparison as an experimental value, and compare this standard value with the measured value to determine the degree of closure X. It is also possible. Calculation formula 1'+may be stored in the ROM memory in advance. In step 204, this degree of occlusion is displayed on the CRT. As shown in FIG. 3, values such as measurement conditions can be stored in the memory and output later as desired. In step 205, it is determined whether a predetermined measurement time, for example 15 seconds, has ended. If the process has not finished, wait for 3 seconds, for example, at step 206, and then return to step 202. The measurement is performed for a predetermined period of time from step 202 to step 2O5, and the measurement is completed in step 207 and the average value of the degree of occlusion is displayed, and the measurement is completed in step 208.
よってＣＲＴ上には各種の条件と共に閉塞度が表示され
、この閉塞度を考慮して次の作業を検問する。Therefore, the degree of occlusion is displayed together with various conditions on the CRT, and the next task is checked in consideration of this degree of occlusion.

を摘出することが可能である。Once the degree of occlusion of the pipeline to be cleaned is clear, the cleaning method is then determined. There are two main types of purification methods: chemical methods and mechanical methods. Furthermore, chemical methods are divided into chemical cleaning methods and combination methods, and mechanical methods include direct polishing methods, high-pressure jet methods, and lint blasting methods. Generally, the decision on which method to use should be made after an initial inspection of the line to be cleaned. In this invention, since the degree of occlusion X has already been determined, it is possible to extract a more appropriate method for cleaning the canal.

The particle size of the abrasive and the injection pressure can be adjusted appropriately.
