Problems solved by technology
[0003] At present, the single-end jacking construction method is adopted in the construction of ultra-long horizontal pipe curtains. Due to the long jacking distance, the pipe curtain jacking direction often deviates during the actual construction process and it is difficult to correct the deviation, which leads to jacking failure and other accidents, causing unsatisfactory Necessary waste and delays

The invention discloses a control device and method used for jacking construction of an ultra-long horizontal pipe curtain and based on inclination measurement. The control device comprises a jacking system, a testing system and a deviation rectification system. The testing system is connected with an inclination measurement device or a sensor, a reading instrument and a computer through a communication cable, and the inclination measurement device or the sensor is mounted on the pipe curtain. The deviation rectification system is connected with the computer, a deviation rectification controller and a deviation rectification device mounted on the pipe curtain through a communication cable. During actual operation, the control method comprises the following steps that firstly, the deviation condition of the pipe curtain jacking axis is measured and calculated in real time through the testing system; and if the deviation exceeds a specified value, the deviation rectification angle is calculated through the computer according to the deviation amount and input to the deviation rectification controller, and the deviation rectification device is further driven by the deviation rectification controller to conduct adjustment for deviation rectification. By adoption of the control device and method, the posture of the pipe curtain axis can be monitored and adjusted in real time in the jacking process of the ultra-long horizontal pipe curtain, the jacking precision of the pipe curtain can be ensured, and preset design requirements can be met.
Description
technical field [0001] The invention belongs to the technical field of rock-soil proximity construction, and in particular relates to a super-long horizontal pipe curtain jacking construction control device and method based on inclination measurement. Background technique [0002] With the vigorous development of my country's infrastructure construction, a large number of various geotechnical proximity construction projects have emerged, such as tunnels passing through existing sensitive structures. During the construction of this type of project, due to the existence of the surrounding existing buildings, the requirements for deformation control are extremely high. Therefore, in the actual construction process, auxiliary construction measures such as horizontal pipe sheds and pipe curtains are often used, and the crossing distance is getting longer and longer. Further, super-long horizontal tube sheds or tube curtains appeared. [0003] At present, the single-end jacking m...
