| titleOfInvention | A shield butt joint freezing reinforcement device |
| abstract | The invention provides a shield butt joint freezing reinforcement device, which includes a shield machine, a freezing pipe, a soil area division unit, a water content detection mechanism, a host computer, and a freezing pipe adjustment mechanism. The steps of the freezing reinforcement method are: modifying the shield machine Relative position, so that the axes of the shield machines on both sides are consistent; divide the soil area outside the end of the shield machine, and detect the water content of different soil areas; adjust the position of the freezing tube in different soil areas according to the water content of the soil Distribution; put low-temperature salt water into the freezing pipe to freeze the soil outside the end of the shield machine; remove the cutter head of the shield machine, weld the water-stop connection steel ring plate, divide the soil area, and After the moisture content is detected in the soil body area, the distribution quantity and interval of the freezing tubes on one side of different soil body areas can be adjusted accordingly, so that the cold energy transfer can be used to the maximum extent for freezing, preventing the waste of cold energy and improving the freezing efficiency. |
