DETAILED DESCRIPTION

[0021] Example 1, as Figures 1-5As shown, a jacking pipe four-point measuring prism mounting device includes a U-shaped bracket 1. A wing screw 2 is threaded onto the upper part of the U-shaped bracket 1. The screw head of the wing screw 2 located inside the U-shaped bracket 1 is rotatably connected to a fixed circular plate 3. A T-shaped slot 11 is provided on the lower part of the front of the U-shaped bracket 1. The screw head of the connecting screw 4 is engaged in the T-shaped slot 11 and locked and fixed by a locking nut 41. The lower part of the connecting screw 4 is connected to a positioning nut 42 and a fixing nut 43 respectively. An L-shaped bracket 5 is sleeved on the outer surface of the connecting screw 4 between the positioning nut 42 and the fixing nut 43. A prism 6 is connected to the lower left side of the L-shaped bracket 5 through a fixing screw 51.

[0022] In this embodiment, the maximum width of the T-shaped slot 11 matches the screw head of the connecting screw 4. It should be understood that after the screw head of the connecting screw 4 is installed in the T-shaped slot 11, when the locking nut (41) is rotated, the connecting screw 4 will not rotate due to the limitation of the width of the T-shaped slot 11.

[0023] In this embodiment, the outer surface of the butterfly screw 2 between the screw head of the butterfly screw 2 and the upper surface of the U-shaped bracket 1 is also provided with an anti-retraction nut 21. After the butterfly screw 2 is inserted into the pipe wall of the tail section of the pipe jacking machine through the U-shaped bracket 1, the butterfly screw 2 is tightened and the anti-retraction nut 21 is further tightened so that the device will not easily loosen under the influence of long-term mechanical vibration and other factors.

[0024] Example 2, as Figures 1-9 The embodiment shown in this example, based on embodiment 1, further includes a protective cover 7. The protective cover 7 has two parallel fixing plates 71 on its upper surface, and a U-shaped latch 72 on the side surface of the protective cover 7 between the two fixing plates 71. The front of the U-shaped latch 1, located above the T-shaped latch 11, has two L-shaped latches 12. The fixing plates 71 on top of the protective cover 7 can engage with the L-shaped latches 12. The protective cover 7 can protect the prism in this device from impacts during construction, preventing damage or displacement of the prism and ensuring the normal progress of subsequent measurement work.

[0025] In this embodiment, the outer surface of the U-shaped card holder 1 on both sides of the L-shaped card slot 12 is also provided with a plurality of set screws 13, which facilitates fixing the fixing plate 71 that is inserted into the L-shaped card slot 12.

[0026] In this embodiment, an observation hole 73 is provided in the center of the front panel of the protective cover 7. The center of the observation hole 73 should coincide with the center point of the prism 6 mounted on the L-shaped bracket 5 inside it. When using a total station for measurement, even if it deviates from a certain angle, the center of the prism 6 can still be aimed.

[0027] How to use this utility model;

[0028] After the device is assembled, the positioning nut 42 and the fixing nut 43 are adjusted so that the center of the prism is substantially coincident with the center of the observation hole 73; then four sets of the device are carried to the construction site, the surveyor aims at the pipe jacking machine tail through the total station, determines the installation position of the prism, and instructs the staff to install the device to the accurate position of the pipe jacking machine tail; during subsequent surveying, the surveyor only needs to aim at the prism in the device to perform the surveying work, thereby saving a large amount of time for the pipe jacking engineering surveying work and improving the surveying precision.

[0029] In the above embodiments, the U-shaped clamping seat 1, the butterfly screw 2, the connecting screw 4, the protective cover 7, and the screw and nut assembly can be made of stainless steel, which prevents rusting and prolongs the service life in a relatively humid construction environment.

[0030] The above-described specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the application. It should be understood that the above-described embodiments are only specific embodiments of the application and are not intended to limit the application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the application shall be included in the protection scope of the application.
