도 2는 본 발명의 공정제어 흐름도이다.2 is a process control flowchart of the present invention.

본 발명에 따르면, 2차 급수펌프(5)로써 믹서(6)에 공급되는 물의 양을 믹서 (6)의 하단에 부착된 로드셀로 구성된 물량 및 시멘트량 계측 센서(9)로써 계측하여 그 양이 500Kg일 때 2차 급수펌프(5)를 OFF하는 제 1단계와, 시멘트 사일로(1)의 수직 스크류를 작동시켜 믹서(6)로 공급되는 시멘트의 양을 믹서(6)의 하단에 부착된 로드셀로 구성된 물량 및 시멘트량 계측 센서(9)로 측정하여 1000Kg에서 시멘트 사일로(1)를 정지시키는 제 2단계와, 믹서(6)에서 계근된 물과 시멘트로써 혼합한 후 혼합물을 토출구를 통해 아지테이터(7)로 보내고, 믹서(6)내의 혼합물이 30Kg 이하가 되면 믹서(6)의 토출구를 폐구하는 제 3단계와, 다시 믹서(6)에 물과시멘트를 공급하여 혼합하는 상기 단계의 반복이 행해지는 제 4단계와, 아지테이터 (7)의 하단에 부착된 물량 및 시멘트량 계측 센서(9)로써 아지테이터(7)를 계량하여 아지테이터(7) 용량이 Full일 경우에는 믹서(6)의 토출구를 폐구시키고, 아지테이터(7)의 용량이 Empty일 경우에는 믹서(6)의 물공급 라인과 시멘트 공급라인을 개구시키는 제 5단계와, 교반된 슬러리를 슬러리 펌프(8)에 공급하는 제 6단계로 구성되어 진다.According to the present invention, the amount of water supplied to the mixer 6 as the secondary feed pump 5 is measured by the amount of water and cement amount measuring sensor 9 composed of a load cell attached to the bottom of the mixer 6, The load cell attached to the bottom of the mixer 6, the first step of turning off the secondary feed pump 5 when 500kg, and the amount of cement supplied to the mixer 6 by operating the vertical screw of the cement silo 1 A second step of stopping the cement silo 1 at 1000 kg by measuring with a quantity of water and a cement amount measuring sensor 9, and mixing the water with the cement weighed in the mixer 6 and then mixing the mixture with an agitator through the discharge port. (7), when the mixture in the mixer 6 is 30 Kg or less, the third step of closing the discharge port of the mixer 6 and the repetition of the step of supplying and mixing water and cement to the mixer 6 again. The fourth step performed and the amount of water and cement amount attached to the lower end of the agitator 7 The agitator 7 is measured by the sensor 9, and when the capacity of the agitator 7 is full, the discharge port of the mixer 6 is closed. When the capacity of the agitator 7 is empty, the mixer 6 And a fifth step of opening the water supply line and the cement supply line, and a sixth step of supplying the stirred slurry to the slurry pump (8).

상기 단계중에서 특히 제 5단계를 상술하면, 아지테이터(7)의 용량별로 구별하여 관리하게 되는데, 아지테이터(7)가 Full인 경우에는 믹서(6)의 토출구만 폐구시키고, 믹서(6)의 교반기만 작동시킨다. 이는 아지테이터(7)에서 슬러리 설정량(최소값 3,000Kg)을 송출한 후에 믹서(6)에서 혼합된 슬러리를 곧바로 아지테이터 (7)로 공급될 수 있도록 함이다. 그리고, 아지테이터(7)가 Empty인 경우에는 믹서 (6)의 입구측에 물과 시멘트의 공급 라인을 개구시켜 필요 슬러리의 생산을 준비케 한다.Particularly, the fifth step in the above steps is managed by the capacity of the agitator 7. When the agitator 7 is full, only the discharge port of the mixer 6 is closed and the mixer 6 is closed. Only operate the stirrer. This allows the slurry mixed in the mixer 6 to be directly supplied to the agitator 7 after the slurry set amount (minimum value 3,000 Kg) is sent out from the agitator 7. When the agitator 7 is empty, a supply line of water and cement is opened at the inlet side of the mixer 6 to prepare for production of the required slurry.

상기와 같이 구성된 공정관리 시스템은 물량 및 시멘트량 계측 센서(9)와 슬러리량 계측 센서(10)에 의해 계측된 양을 연산하여 "물의 양"과, "물의 양＋시멘트의 양"과, "슬러리의 양"을 검출된 시간과 함께 출력하게 된다. 이와 같이 자동화된 관리 시스템에 의해 인위적인 조작의 경우가 배제되고, 세팅된 시간 간격으로 중요 계측량을 출력함으로서, 관리자는 출력 데이터를 봄으로써 계획된 슬러리의 조성비를 검사할 수 있고, 시간과 함께 출력되는 계측량들에 의해 공정 및 시공의 시간 관리가 가능할 뿐만 아니라, 시공 후에도 출력 데이터에 의해 시공 부분의 양부를 판단할 수 있어 재 시공의 경우에는 불량 부분만을 찾아 재시공할 수 있어 시간과 비용이 절감된다.The process management system configured as described above calculates the quantity measured by the quantity of water and the amount of cement measurement sensor 9 and the amount of slurry measuring sensor 10, and "water amount", "amount of water + amount of cement" and " Volume of slurry "along with the detected time. By eliminating the case of man-made operation by this automated management system, and outputting the important measured amount at the set time interval, the administrator can check the composition ratio of the planned slurry by viewing the output data, and output with time. Not only is it possible to manage the process and construction time by measured quantities, but it is also possible to judge the quality of the construction part based on the output data even after construction. .

이와같이 본 발명은 지반개량공법에서 물과 시멘트가 혼합 및 교반되는 양을 센서에 의해 자동으로 계측하고 출력하게 함으로써, 종래 목측에 의한 비효율적인 시공 관리를 전산화할 뿐만 아니라, 시공 관리를 테이터화하여 축적 보관함으로써 설계와 시공이 일치된 전산 자료로써 증명할 수 있어 시공의 공정성과 신뢰성을 높일 수 있고, 설계와 시공의 품질을 비교 검토할 수 있는 데이터 베이스화가 가능하여 시공기술의 노하우가 실질적인 데이터로 활용되어 산업 발전에 이바지하는 효과가 있다.As described above, the present invention automatically measures and outputs the amount of water and cement mixed and stirred in the ground improvement method by a sensor, thereby not only computerizing inefficient construction management by conventional neck side, but also recording and accumulating construction management. By storing it, it can be proved by computerized data that is consistent with design and construction. It can improve the fairness and reliability of construction, and it is possible to make a database that can compare and examine the quality of design and construction. It has the effect of contributing to industrial development.
