Problems solved by technology
When laying stakes with measuring instruments, it is also difficult to operate due to insufficient night vision conditions
For the non-contact pile driving system of the piling platform, such as the water piling system, the positioning information is provided through the RTK measuring instrument, and the coordinates need to be input on site. The pile position will be shifted during the offshore operation of the pile driver, and it cannot be obtained. The deviation of the pile position during the construction process may easily cause the deviation error to exceed the accuracy requirements after the completion of the pile construction, and cannot meet the accuracy requirements of the operation.

The invention discloses a non-contact measurement piling system, which includes a measurement device, a data processing unit, a data transmission unit, and a main control unit; Both the receiver and the rangefinder send real-time measurement data to the data processing unit and the main control unit through the data transmission unit; the data transmission unit is used to receive the real-time measurement data of the measuring equipment and transmit it to the data processing unit and the main control unit; the data processing unit It is used to calculate the posture parameters of the piling platform according to the measurement coordinates of the two GNSS receivers and the hull coordinates, and calculate the actual position of the pile core by combining the actual distance from the pile body measured by the two range finders in real time; the main control The unit is used to obtain the target pile core position input by the user, and prompt the user to adjust the pile driving position according to the actual pile core position until the pile driving is completed. The invention can improve the precision of piling operation and control the error range within the allowable range.
Description
technical field [0001] The invention relates to the field of intelligent surveying and mapping, in particular to a non-contact measuring piling system and a piling placing method. Background technique [0002] At present, during the construction of the pile driver, the placement of the pile needs to pass through a general-purpose measuring instrument, and at the same time, it needs the cooperation of multiple people. When laying pile positions by measuring instruments, it is also difficult to operate due to insufficient night vision conditions. For the non-contact pile driving system of the piling platform, such as the water piling system, the positioning information is provided through the RTK measuring instrument, and the coordinates need to be input on site. The pile position will be shifted during the offshore operation of the pile driver, and it cannot be obtained. The deviation of the pile position during the construction process may easily cause the deviation error t...
