Specific embodiment
With reference to the accompanying drawing and specific embodiment is further elaborated the utility model.
As shown in Figure 1, it includes internal measurement portion 100 and whole measurement portion 200 that the utility model grouting, which lifts measuring system,
Wherein internal measurement portion 100 is mainly used for measuring the deformation around the crack to be filled 5 that stress is more concentrated, including substantially water
It flat the first supporting station 115, the pulley yoke 112 for being fixed on the first supporting station, the pulley 111 being installed on pulley yoke 112 and puts
It is placed in the movable block 113 of the first supporting station 115, the first amesdial 13 is fixed on the first supporting station, and movable block 113 is located at first
13 lower section of amesdial and the contact perpendicular contact with the first amesdial 13.First fixed part 12 is substantially concordant with pulley 111 and leads to
It crosses drawstring 14 to be connected with movable block 113, drawstring 14 bypasses pulley 111.When the first supporting table 115 and the first fixed part 12 are being in the milk
When relative displacement occurring under pressure, drawstring 14 pulls movable block 113 to move upwards, and movable block 113 squeezes the first amesdial 13
Contact makes the first amesdial 13 generate reading, and the difference of reading for front and back of being in the milk is position of first fixed part 12 relative to pulley 111
Shifting amount.
Further, in order to reduce the stress of drawstring 14, also for movable block 113 can steady activity, in movable block 113
And first be equipped with an elastic element 114 between supporting station 115.When installation, 114 one end of elastic element is first fixed on first
Cushion cap 115, then 114 other end of elastic element is fixed on movable block 113, the first amesdial 13 is then fixed again, is made initial
Under state, movable block 113 is in contact with the contact of the first amesdial 13 and the reading of amesdial is zero.Specifically, elastic element
114 select the pressure spring for being suitable for for a coefficient of elasticity, after so that it is met installation according to the method described above, in the range ability of amesdial
Interior, pressure spring is in compressive state always.After the first elastic element 114, drawstring 14 is only subjected to lesser pulling force
By 113 pull-up of movable block, the accuracy of result ensure that, also reduce the requirement to 14 intensity of drawstring.
Whole measurement portion 200 is mainly used for measuring whole the lifting relative to basement rock of impervious body 3, including the second supporting station 22
With the second amesdial 23, go deep into the peephole 214 of impervious body basement rock 4, and is inserted into 211 He of observation inner tube of the peephole 214
Outer tube 212 is observed, wherein observation 211 bottom end of inner tube is fixed on 214 bottom of peephole by cement 215, observation outer tube 212 is arranged
Outside observation inner tube 211, the top of observation outer tube 212 is fixed on 3 surface of impervious body, observation outer tube 212 and observation inner tube 211 it
Between filling 213 axle envelope of fine sand fix, the second amesdial 23 be fixed on observation 211 top of inner tube.Second supporting station 22 is one basic
Horizontal table top before grouting, adjusts the position of the second amesdial 23, and the contact of the second amesdial 23 and the second supporting station 22 is made to hang down
Directly touch, the difference of reading by reading the second amesdial 23 of front and back that is in the milk can be obtained impervious body 3 it is whole lift value.
Further, be mounted with respectively on the first amesdial 13 and the second amesdial 23 first alarm (not shown) and
Second alarm (not shown) adjusts the installation site of the first amesdial 13 and the second amesdial 23, makes the initial reading of the two
It is zero, then a preset value is set on alarm, when the reading of the first amesdial 13 is more than preset value, the first alarm is opened
Dynamic alarm, when the reading of the second amesdial 23 is more than preset value, the starting alarm of the second alarm, the same alarm clock of alarm principle
It is identical.So, it deforms in small range and under lifting, is read without manual record amesdial, when deforming and lift more than one
After determining range, alarm occurs, then artificial progress read-record.It can simplify in this way and lift record operation, improve working efficiency.
The utility model is not limited to above-mentioned optional embodiment, anyone can obtain under the enlightenment of the utility model
Other various forms of products, however, making any variation in its shape or structure, all the utility model rights that falls into are wanted
The technical solution in confining spectrum is sought, is all fallen within the protection scope of the utility model.
