Description

Variable mixing machine and variable deep mixing method using it

본 발명은 가변형 교반장치 및 이를 이용한 가변형 심층혼합처리공법에 관한 것이다.
The present invention relates to a variable stirring device and a variable depth mixing treatment method using the same.

최근에 해안항만개발, 기초지반개량, 오염부지개선, 오염환경복구 등의 사업과 관련하여 항만, 호안, 물양장, 하천제방, 쓰레기매립장, 광해복구 등에 지반보강 및 지반차수 목적으로 지중에 연속벽을 형성하는 심층혼합처리공법이 적용되고 있다. In recent years, continuous walls have been added to the ground for reinforcement and ground reclamation for ports, lakes, water reservoirs, river embankments, landfills, and mine rehabilitation in connection with projects such as coastal port development, ground improvement, contaminated land improvement, and pollution environment recovery. The deep mixing treatment method to be formed is applied.

기존의 심층혼합처리공법에서 사용되는 굴진장치는 굴진축의 이동 및 회전이 불가능한 문제점을 가지고 있다. 따라서 다축을 이루는 굴진축의 이동이 불가능하여 다축 간의 거리조정이 되지 않아 다축의 굴진 및 교반작업에 의하여 지중에 형성된 지중기둥체 간의 오버랩 길이를 조정할 수가 없고, 또한 크레인에 직교한 방향으로만 다축이 고정형으로 장착되어 있어 다축을 이루는 굴진축의 회전이 불가능하여 굴진축의 방향을 조정할 수가 없으므로 크레인에 직교한 방향으로만 다축의 시공이 가능하여 크레인의 진입 및 운전이 불가능한 현장에서는 시공을 할 수가 없는 상황이다. 그리고 기존의 공법은 굴진축의 굴진시 굴진속도의 변화에 따라 고화액의 공급량은 항상 일정하게 공급이 되어 고화액이 불필요하게 낭비되고 있는 실정이다. Excavator used in the existing deep mixing process has a problem that the movement and rotation of the drilling shaft is impossible. Therefore, it is impossible to move the multi-axis excavation shaft, so the distance between the multi-axes cannot be adjusted. Therefore, the overlap length between the underground pillars formed in the ground by multi-axis excavation and stirring cannot be adjusted, and the multi-axis is fixed only in the direction perpendicular to the crane. Since it is impossible to adjust the direction of the excavation shaft because it is impossible to rotate the multi-axis excavation shaft, the construction of the multi-axis is possible only in the direction orthogonal to the crane. In addition, according to the conventional method, the amount of solidified liquid is always supplied constantly according to the change in the excavation speed during the excavation of the excavating shaft, and the solidified liquid is unnecessarily wasted.

따라서 심층혼합처리장치를 이루는 다축 간에 거리조정이 되어 다축의 굴진 및 교반작업에 의하여 지중에 형성된 지중기둥체 간의 오버랩 길이가 조정할 수 있는 장치 및 공법의 개발이 요구된다. 그리고 크레인에 직교한 방향 뿐만아니라 수평 또는 경사진 방향으로도 다축의 회전이 가능하여 크레인의 진입 및 운전이 불가능한 현장에서도 시공이 가능한 심층혼합처리 장치 및 공법의 개발이 요구된다. 그리고 굴진축의 굴진시 굴진속도의 변화에 따라 고화액의 공급량이 변화되도록 공급되어 고화액의 낭비를 지양하는 것이 요구된다. Therefore, there is a need to develop a device and a method for adjusting the overlap length between underground pillars formed in the ground by adjusting the distance between the multi-axes constituting the deep mixing treatment apparatus. In addition, it is required to develop a deep mixing apparatus and a construction method that can be constructed even in a site where the entry and operation of the crane is impossible because the multi-axis can be rotated in the horizontal or inclined direction as well as the direction orthogonal to the crane. And it is required to avoid the waste of the solidified liquid is supplied so that the supply amount of the solidified liquid in accordance with the change of the excavation speed during the drilling of the excavating shaft.

If it is connected to the motor, the grouping (17) when the motor and the gearbox is mounted on the upper end of the shaft, the multi-axis shaft to rotate the gearbox is connected to rotate the multi-axis shaft of the shaft in groups, When only the motor is mounted on the top of the shaft, the entire motor mounted on the top of the shaft of the shaft is rotated in groups to rotate the shaft of the shaft in groups, and the grouping is operated by a motor or a separate hydraulic jack or driving motor. do.

굴진축의 상단에는 모터(15)와 기어박스(16)가 모두 장착되거나 또는 모터(15)만 장착되고, 모터와 기어박스가 모두 장착된 경우에는 굴진축이 기어박스에 연결되고, 모터와 기어박스가 모두 장착된 경우에는 모터의 회전력이 기어박스를 통하여 굴진축에 전달된다. 기어박스는 모터의 회전력을 인가받아 굴진축에 회전력을 전달하고, 기어박스가 굴진축에 회전력을 전달하는 것은 모터의 회전력이 기어박스 내에서 다축의 굴진축 중에 가운데의 중심축(11)의 기어(16-1)에 전달되고, 중심축의 회전력이 기어박스 내에서 다른 개별축(10)의 기어(16-1)에 전달되는 것이다. At the top of the drilling shaft, both the motor 15 and the gearbox 16 are mounted or only the motor 15 is mounted.

When only the motor is mounted, the drilling shaft is connected to the motor. When only the motor is mounted, the rotational force of the motor is directly transmitted to the drilling shaft. When both the motor and the gearbox are mounted, the downward movement 21, the upward movement 22, individual axis rotation, and group axis rotation are possible, and the lateral movement 20 is impossible. When all the boxes are installed, the lateral movement is impossible, because the horizontal distance between the individual axes constituting the multi-axis drilling axis connected to the gearbox is fixed, so that it is impossible to adjust the horizontal distance between the individual axes constituting the multi-axis drilling axis. will be. When only the motor is mounted, the lateral movement, the downward movement, the upward movement, the individual axis rotation, and the group axis rotation are possible. When only the motor is mounted, it is possible to move in the lateral direction. The motor mounted on each individual axis constituting the multiaxial axis can move in the lateral direction.

The individual shaft rotation 30 has a forward rotation and a reverse rotation, the individual shaft constituting a single axis of the axis of rotation is possible to both forward and reverse rotation, the individual shaft constituting the axis of multi axis shaft is a motor and gearbox on the top of the shaft axis If all are fitted, forward or reverse rotation is possible. The individual shafts that make up the multi-axis shaft can be rotated forward and reverse when only the motor is mounted on the top of the shaft.

굴진축이 상방향이동 또는 하방향이동 시에는 굴진축이 리더(12)를 따라 이동하게 되고, 굴진축이 리더를 따라 이동할 시에는 자유이동 또는 톱니이동을 한다. 자유이동은 굴진축의 상단에 모터와 기어박스가 모두 장착된 경우 또는 자중이 무거운 중량의 모터만 장착된 경우에 해당되고, 자유이동은 리더에 장착된 모터, 기어박스의 자중에 의하여 굴진축이 리더를 따라 자유이동하는 것이고, 자유이동시 자중에 더하여 피스톤의 적용이 가능하다. 피스톤은 모터 또는 기어박스의 상단에 장착되어 모터 또는 기어박스를 하방향으로 누르는 작용을 하고, 피스톤이 모터 또는 기어박스를 하방향으로 누르게 되면 모터 또는 기어박스에 장착된 굴진축은 리더를 따라 자중 및 피스톤 누름에 의하여 하방향으로 자유이동한다. 피스톤은 모터 또는 별도의 유압잭 또는 구동모터로 작동된다. When the shaft is moved upward or downward, the shaft is moved along the leader 12, and when the shaft is moved along the leader free movement or tooth movement. Free movement corresponds to the case where both the motor and the gearbox are mounted on the top of the drilling shaft, or only the motor of the heavy weight is installed. The free movement refers to the movement of the leader shaft by the weight of the motor and gearbox mounted on the reader. It is free to move along, and it is possible to apply a piston in addition to its own weight during free movement. The piston is mounted on the top of the motor or gearbox to press down on the motor or gearbox. When the piston presses on the motor or gearbox downward, the drilling shaft mounted on the motor or gearbox follows the leader Free movement in the downward direction by pressing the piston. The piston is operated by a motor or a separate hydraulic jack or drive motor.

The tooth movement corresponds to the case where only the light weight motor with light weight is mounted on the top of the excavation shaft. The tooth movement is lightweight because the motor mounted on the leader 12 is light and the excavation shaft cannot move freely along the leader due to the weight of the motor. In this case, the tooth movement is caused by the rotational teeth 19 of the motor to rotate along a tooth length 18 of a constant length formed in the longitudinal direction of the leader, so that the motor moves along the tooth length 18 and at the same time Connected drilling axes move along the leader.

On the contrary, if the ground resistance is small, the rotational speed of the motor increases and the excavation speed increases. As the excavation speed is changed, the amount of solidified liquid is automatically changed. The supply amount of the solidified liquid is automatically changed by detecting the excavation speed at the excavation of the excavating shaft and automatically changing the supply amount of the solidified liquid according to the detected excavation speed. If the excavation speed is high speed, the supply amount of solidified liquid is increased. On the contrary, if the excavation speed is low speed, the supply amount of solidified liquid is reduced.
