Referring to fig. 3, a concrete structure of the settlement insulator 31 is shown, in this embodiment, the settlement insulator 31 includes an insulating barrier 311, an insulating cover 312, a hanging airbag 313 and a hanging rope 314; specifically, the isolation baffles 311 are symmetrically arranged between the horizontal embedded culvert 1 and the bearing pile of the building to be tested, the isolation baffles 311 are made of plastic materials, soil between the isolation baffles 311 is taken away to form a channel, the isolation cover plate 312 covers the isolation baffles 311, the isolation cover plate 312 is also made of rigid plastic materials, and a settlement abdicating space 315 is formed between the isolation cover plate 312 and the isolation baffles 311; the hanging airbag 313 is disposed in the subsidence space 315 formed by the isolation baffle 311 and the isolation cover plate 312 for the extension rod 32 to penetrate through, one end of the hanging rope 314 is connected with the isolation cover plate 312, and the other end is connected with the hanging airbag 313 to hang the hanging airbag 313. Subside the setting of isolated ware 31 through this embodiment, at first can completely cut off pre-buried culvert pipe 1 of level and building bearing pile, can not bring the influence to pre-buried culvert pipe 1 of level when the building takes place to subside and incline, on the other hand can drive extension rod 32 and together remove after the slope of angle takes place to subside or the building, and subside the setting up of isolated ware 31 and make extension rod 32's motion not influenced and interfere, further improve the accuracy that the actual test detected the early warning.
Referring to fig. 4, the horizontal holder 33 in this embodiment includes a lifting pressure spring 331, a containing cylinder 332, containing water 333, insulating oil 334, a buoyancy block 335, a mounting cover 336, a weight block 337, and a vertical rod 338; specifically, the bearing cylinders 332 are symmetrically arranged at two ends of the horizontal embedded culvert 1, the lifting pressure springs 331 are arranged between the horizontal embedded culvert 1 and the bearing cylinders 332 to lift and mount the bearing cylinders 332, the same bearing cylinders 332 are also made of plastic materials, and the bearing cylinders 332 are lifted and mounted by the lifting pressure springs 331, so that the bearing cylinders 332 are prevented from interfering under the condition of external vibration; in the dress water 333 locates the dress section of thick bamboo 332, isolated oil 334 is located dress water 333 top and carries out isolated sealing in order to hold dress water 333, buoyancy piece 335 floats in the top of mounting bracket, the installation is covered 336 lid and is fitted on dress section of thick bamboo 332, balancing weight 337 passes through the rope hoist and mount on buoyancy piece 335 and extend down, buoyancy piece 335 top is located to vertical pole 338 an organic whole and pass the vertical upwards extension of installation lid 336, set up on the installation lid 336 and supply vertical pole 338 to wear to establish the through-hole 3361 that slides, and wear to establish between hole 3361 and the vertical pole 338 the airtight lubricating oil of fat liquoring and form sealed, the one end that buoyancy piece 335 was kept away from to vertical pole 338 is connected with slope atress pole 34 middle part rotation. Can guarantee that pre-buried culvert pipe 1 of level probably can not guarantee absolute level at the in-process of installation, so bring certain experiment detection error, and the level keeps the setting of ware 33, can guarantee that the fulcrum of slope atress pole 34 can guarantee absolute level to the detection effect that still can accomplish accurately taking place the phenomenon of geological disasters, further reduce the existence of error.
Referring to fig. 5, it has been described above that when the building container is settled or the inclination angle is changed, the extension rod 32 can be driven to move, and the movement of the extension rod 32 will synchronously drive the inclination amplifier 4 at the other end of the inclined force-bearing rod 34 to work, so as to amplify the phenomenon of the angle or settlement; the tilt amplifier 4 in the present embodiment includes a driving rod 41, a weighted spring rod 42, an illuminating ring lamp 43, a sector baffle 44, a pressing ring 45, and a pressing switch 46; the specific driving rod 41 is arranged in the vertical embedded culvert 2, extends upwards and is rotatably connected with the inclined stress rod 34, the weighted spring rod 42 is arranged in the vertical embedded culvert 2, one end of the weighted spring rod 42 is rotatably connected with the inner side wall of the vertical embedded culvert 2, the other end of the weighted spring rod 42 is rotatably connected with the side wall of the driving rod 41, the gravity of the driving rod 41 can be counteracted through the arrangement of the weighted spring rod 42, so the driving rod 41 can be driven to ascend and descend under the action of slight external force, and on the other hand, the arrangement of the weighted spring rod 42 ensures that the driving rod 41 can not deviate at the position in the middle of the vertical embedded culvert 2; therefore, when the extension rod 32 drives the tilt lever 34 to move, the driving rod 41 at the other end of the tilt lever 34 moves in the opposite direction.
The irradiation annular lamp 43 is installed inside the vertical pre-buried culvert 2 and emits light upwards, the driving rod 41 is provided for penetrating, a sliding hole 431 for allowing the driving rod 41 to slide is formed in the irradiation annular lamp 43, the fan-shaped baffles 44 are rotatably installed on the inner side wall of the upper portion of the vertical pre-buried culvert 2, the side edges of the fan-shaped baffles 44 are mutually abutted to isolate the inner cavity of the vertical pre-buried culvert 2 into an upper inner cavity 47 and a lower inner cavity 48, the irradiation annular lamp 43 is located in the lower inner cavity 48, and the extrusion rings 45 are symmetrically arranged on the driving rod 41 and abutted to the upper side surface and the lower side surface of the fan-shaped baffles 44 (the extrusion rings 45 located below the fan-shaped baffles 44 are not shown in the drawing); therefore, in the process of the movement of the actual driving rod 41, the extrusion ring 45 can be driven to move upwards or downwards, so as to drive the fan-shaped baffles 44 to be unfolded upwards or downwards, after the fan-shaped baffles 44 are unfolded, the size of the inclination angle of the building can be judged through the size of the gap formed by the unfolding of the adjacent fan-shaped baffles 44, and the irradiation ring-shaped lamp 43 can provide a light source to realize more convenient observation.
It should be noted that, in this embodiment, the extrusion rings 45 located at the upper and lower sides of the sector-shaped baffle 44 have a certain distance (not shown in the figure) from the sector-shaped baffle 44, so that no interference is formed no matter the sector-shaped baffle 44 moves upwards or downwards, that is, the situation that the sector-shaped baffle cannot turn upwards or downwards does not occur, and the distance does not affect the accuracy of the overall detection within the measurement operation range.
Through the mutual matching of the structures, whether the building descends or inclines at an angle or not or whether the building inclines after settlement occurs or not can be judged; on the first hand, when the falling occurs, the driving rods 41 at both ends will move and rise, so the fan-shaped baffles 44 at both ends are unfolded on the same line; in the second aspect, when the angle is inclined, the unfolding is carried out upwards and downwards at the same time, and the unfolding amplitudes are the same; the third aspect and when the settlement has the angle inclination, the two sides are different in expansion amplitude, and the more serious angle inclination of which side is judged after the settlement is generated can be judged according to the expansion amplitude.
