Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Figure 1-3, a kind of metro building shield reaction frame, including be arranged perpendicular to ground frame body, fixation Reference rings 1 in the middle part of frame body, frame body front side are fitted with strain gauge 2;Frame body include upper supporting beam 3, under Supporting beam 4 and two columns 5;5 upper and lower part of column is solid construction, is hollow structure in the middle part of column 5;Under column 5 End is fixed with pilum 7 by attachment base 6;5 top of column and 5 lower part of column are provided with tapped through hole 8 in left-right direction;Screw thread 8 internal screw thread of through-hole is connected with positioning bolt 9;5 outside of column, 9 end of positioning bolt is rotatably connected to support plate 10;Lower part 8 top of tapped through hole, 5 lower part of column is provided with through slot 11 in the front-back direction;Through slot 11 is oblique and front height is higher than rear end Highly;Cooperation is plugged with oblique top column 12 in through slot 11;12 bottom end of oblique top column is in horizontal direction;5 middle part of column is set along the vertical direction It is equipped with inserted link 13;5 middle part upper end of column and 5 middle part lower end of column are provided with the jack 14 of vertical direction;About 14 jack It is corresponding and mating with inserted link 13;The jack 14 of lower part passes through through slot 11;12 front and rear of oblique top column is along vertical side To being provided with location hole 15;Jack 14 corresponding matching of the location hole 15 with lower part;13 top of inserted link is fixed with driving lever 16;It is vertical 5 front side of column is provided with sliding slot 17 along the vertical direction;Driving lever 16 passes through sliding slot 17 and is slidably matched with sliding slot 17;Upper supporting beam 3 with it is vertical The stiffening plate 18 being arranged in eight words is fixedly connected between column 5 between lower supporting beam 4 and column 5;It is cased on positioning bolt 9 Tight loop 19;Tight loop 19 is fixed on 5 inside of column.
When positioning the utility model, pilum 7 is embedded under bottom plate and is fixed first, screws positioning spiral shell everywhere later Bolt 9 contacts support plate 10 with subway tunnel inner wall;When using straight support mode, oblique top column 12 is slided along through slot 11, is such as schemed Shown in 2, inserted link 13 is inserted at the location hole 15 at 12 rear portion of oblique top column at this time, can make the whole rear side of frame body in this way Face is contacted with headwall, increases straight support area, improves straight support performance;When using diagonal brace mode, 17 driving lever is stirred along the chute 16 move up inserted link 13, so that inserted link 13 is detached from location hole 15, later slide backward oblique top column 12 along through slot 11, when oblique top column 12 After the contact base plate of bottom end, inserted link 13 be can be plugged into the location hole 15 of 12 front of oblique top column, and oblique top column 12 is positioned, and be realized (different locations such as in the present embodiment, oblique top column 12 can also be set as at multiple groups or upper beam, column 5 top, make the mode of diagonal brace Used time is selected according to the actual situation).
Although some reaction frames, which can also be not only suitable for directly supportting, is suitable for diagonal brace again, often its straight support mode cannot make frame Body is integrally contacted with headwall, and the stability and fastness directly supportted is insufficient.
Distributed optical fiber stress sensor 2 (not indicating in component home figure) is used in the present embodiment, passes through inside of optical fibre The variation of the strain along optical fiber different location is detected, really distributed measurement is realized, so that real-time monitoring frame body is every Stress situation at one, when discovery somewhere stress is constantly in the pole close to or over frame body material itself in a long time When limiting stress, the risk of deformation there is herein, staff can adjust to progress reinforcement of weld herein or slightly at this time Shield machine working frequency is to reduce stress etc., to avoid the risk deformed at this, after deforming with frame bodies such as traditional approach again The mode warned is compared, with the obvious advantage.
