Detailed Description
The present invention will be further described with reference to the following drawings and examples, which should not be construed as limiting the present invention.
The utility model provides a novel shield constructs tunnel measurement and forces centering with waist device, it includes channel-section steel 1, No. two channel-sections 2, adjusts reinforcing bolt nut 3, base plate 4, centering bolt 5.
As shown in the attached drawings, the first channel steel 1 and the second channel steel 2 are both made of channel steel with the thickness of 5 mm and are used as bearing structures. No. two channel-section steel 2's one end welding is in on the channel-section steel 1, wherein No. two channel-section steel 2's welding angle and position depend on the position that this device installed on the pipe fitting, and the purpose makes No. two channel-section steels 2 after the installation finishes be the horizontal angle. Adjusting and reinforcing bolt nut 3 sets up two, welds nut wherein respectively the both sides of a channel-section steel 1, the welding position is asymmetric, and its effect carries out the micro leveling after this device installation is accomplished. Base plate 4 sets up two, welds respectively No. 1 both ends of channel-section steel are horn mouth form after the welding. All be equipped with the bolt hole on base plate 4. No. two channel-section steels 2 keep away from section of jurisdiction one end and are provided with the bolt hole, centering bolt 5 through No. two channel-section steels 2's bolt hole with No. two channel-section steels 2 are connected. The base plates 4 at the two ends of the first channel steel 1 are respectively connected at the two ends of the segment bolt 7 of the shield tunnel segment 6 and fixedly connected with the shield tunnel segment 6.
For guaranteeing that the measuring instrument installation is stable, improve measurement accuracy, the utility model discloses in still can No. two 2 upper portions of channel-section steel set up measurement positioning disc 8, measurement positioning disc 8 passes through centering bolt 5 with No. two channel-section steels 2 link together.
When this device is installed, generally select near 6 position and 12 position (concrete position can be adjusted according to actual conditions) at the shield tunnel section of jurisdiction, the section of jurisdiction bolt 7 of relevant position must be demolishd during the installation, install this device on section of jurisdiction bolt 7 mouth that corresponds (demolish stagnant water rubber ring that the in-process drops with section of jurisdiction bolt 7 before the installation and resume the normal position, prevent that novel bracket position from appearing the percolating water and leading to the section of jurisdiction displacement to appear) and carry out preliminary fixed with the section of jurisdiction bolt 7 connection of demolising before, later utilize the horizon rule and adjust reinforcing bolt to carry out the leveling, at last with section of jurisdiction bolt 7 and adjust reinforcing bolt nut 3 retightening, avoid rocking about the device, guarantee the stability of device.
Other parts in this embodiment are the prior art, and are not described herein again.
