Embodiment 1

[0025] Such as figure 1 As shown, the long-distance linear pipe jacking center simple control measurement system includes a pipe jacking device, a laser pointer and an adjustable pen holder device. Several adjustable pen holders and laser pointers distributed at equal intervals are installed on the center line of the pipe jacking described above. The laser emitting direction of the pen points to the direction of pipe jacking. A measuring instrument is installed in the working shaft, and the centerline of the pipeline is established by the measuring instrument, so that each laser pen and the centerline of the pipeline coincide in the same straight line. The center of the pipe jacking head is set With a target, the laser pointer close to the pipe jacking head points to the center of the target, thereby controlling the left, right, up and down deviation of the jacking head.

[0026] The measurement method is as follows: install an adjustable pen holder at the center line of the p...

Abstract

The present invention relates to the technical field of top pipe measurement, and specifically relates to a long distance linear top pipe center simple control measuring system and a method, the system includes a top pipe, laser pens and adjustable pen stand devices, the plurality of equally-spaced-distributed laser pens and adjustable pen stand devices are arranged in the center line of the top pipe, the laser emitting direction of the laser pens uniformly point to the jacking direction of the top pipe, a measuring instrument is arranged in a work well, and the center line of the top pipe is established by the measuring instrument, so that the laser pens and the center line of the top pipe are coincident and located in the same straight line; the center of a machine head of the top pipe is provided with a target marker, and one laser pen near the machine head of the top pipe points to the center of the target marker, so that left and right and up and down deviation of the jacking machine head can be controlled. The measuring system can greatly shorten the time of each time of underground measurement, reduces the intensity of the underground measurement, does not delay the jacking construction of each section of the pipe, speeds up the construction schedule, saves equipment investment cost, is easy to maintain, and can effectively reduce measurement time.

Description

[technical field] [0001] The invention relates to the technical field of pipe jacking measurement, in particular to a system and method for simple control and measurement of long-distance linear pipe jacking centers. [Background technique] [0002] In the pipe jacking construction, in order to ensure the correct penetration into the hole, it is necessary to control the direction of the excavation of the machine head along with the jacking of each section of the pipe so as not to deviate up, down, left, or right. It is mostly controlled by the method of dialing the angle with the laser theodolite or measuring the coordinates with the total station. [0003] With the existing technical method of measuring the center line of long-distance pipe jacking, the vertical deviation is basically measured by the level instrument, and the theodolite or the total station is manually (automatically) transferred multiple times in the pipe, and finally measured to the target at the center of...
