Steel band 1 used in the utility model is the band-like thin steel strip of one fixed width, and 1 end of steel band has in the width direction two
A bolt hole, 1 end of steel band are fixed with 4 connecting cleats 14 of probe with bolt.Fiber grating 12 is U-shaped to be pasted and fixed on steel band 1
Surface, fiber grating 12 are connect with fiber grating demodulation device.After the steel band 1 with fiber grating 12 completes, steel band 1 can
Roll storage.
The utility model pops one's head in 4 lower parts as injection cone, and top is steel band connecting cleat, and steel band connecting cleat two sides have
Bolt hole, corresponding with the bolt hole on steel band, in connection, steel band protrudes into connecting cleat and is aligned bolt hole, then uses bolt
Anchoring.
Steps are as follows for the use of the utility model:
Step 1: removing place sundries, and smooth location places static(al) injection machine, squeezes into earth anchor, this reality according to soil layer type
It is suitable for weak soil with novel, just can guarantee steel band depth of penetration in this way, increase monitoring accuracy.Behind grade, level machine (is used
The levelling rod that scale division value is 1mm is calibrated)；Static(al) injection machine is fixed using earth anchor；As shown in Figure 2 and Figure 3, the bottom end of earth anchor
For helical structure；After earth anchor is screwed in soil, earth anchor protrusion is passed through into ground anchor stock 26, and by 26 both ends of ground anchor stock
Ride over pedestal both ends, then with ground anchor bolt 27 by 26 bolt of ground anchor stock tightly above pedestal.
Step 2: fiber grating 12 is adhered on steel band in advance, and rolls transport, and minimum bend diameter cannot be less than
40mm, in order to avoid damage fiber grating 12.In the pre-connection, optical fiber is connected into demodulator, simple test optical fiber whether can normal reaction,
And edit demodulator.To construction site, after flattening injection machine, by wide 45mm, 4 tops of steel band front end and probe of thick 0.1mm
Connecting cleat 14 is connected, and is anchored using bolt, it is noted that it is not necessary that steel band 1 to be clamped in connecting cleat completely, it is appropriate to retain
Activity space avoids steel band 1 in subsequent penetration process from encountering 3 tube wall of casing and can not adjust.Casing 3 every root long degree 1m, it is transversal
The long 60mm in face, width 30mm, thickness 5mm, steel plate thickness 5mm for fixing, length 1m, the long side phase of width and the cross section of casing
Deng i.e. 60mm.It is computed, casing meets rigidity and intensity requirement.
Step 3: steel band is put into first inside pipe casing by the open end of casing side, by first casing lower half
Part is covered with junction steel plate, and electric screw driver can be used to save time and manpower.Exposed steel band is continued to put
Enter in second casing, by junction steel plate 16 by the opening of the unclosed opening of first casing and second casing
Lower half carries out bridge joint fixation；Contact probe 4 is pressed into the bottom end of first casing simultaneously；Fixture block 6 is stuck on first casing
In respective slot, gable plate 7 is placed on 6 top of fixture block, and rotation hand 9 makes to be pressed in chevron from the lengthening pin 24 on driving chain 5
7 top of plate drives gable plate 7 at the uniform velocity to squeeze into preceding two casings with the speed of 1m/min together with steel band by lengthening pin 24
The soil body is until be deep into second unclosed opening of casing；
Exposed steel band is continued to be put into third root casing, by junction steel plate 16 by second after the injection soil body
The lower half of the opening of the unclosed opening of root casing and third root casing carries out bridge joint fixation, when paying attention to fixed steel plate and
The fixture block groove 18 of casing needs to correspond to；It removes and lengthens existing fixture block 6 and gable plate 7 on pin 24；By the installation of fixture block 6 to top the
In the fixture block groove 18 of two casings, gable plate 7 is placed on 6 top of fixture block, and rotation hand 9 makes to lengthen pin from driving chain 5
24 pulling motions next proceed through static(al) injection machine for casing with the speed of 1m/min at the uniform velocity injection soil to 7 top of gable plate
In body, penetrating speed is unsuitable too fast in order to avoid casing deviates, until being deep into the unclosed opening of third root casing.It repeats later
Above-mentioned steps, by remaining casing injection.In penetration process, 1 situation of steel band should be paid attention at any time, guarantee the width direction of steel band 1
It is parallel with foundation pit sideline to be dug, as shown in figure 11, because 1 both direction rigidity of steel band differs greatly, the only injection side of steel band 1
To correct, the soil body that the deformation of steel band 1 could effectively reflect in Excavation Process is leaned to one side misalignment.
Step 4: when pop one's head in 4 injection hard stratum certain depth when, stop injection；As there is no hard stratum under region to be measured, then
3~4m below probe 4 injection to depth to be measured can just be stopped into injection.When pulling up, gable plate 7 is placed below fixture block,
Hand 9 are inverted, makes to withstand 7 lower section of gable plate from the lengthening pin 24 on driving chain 5, at the uniform velocity pulls up casing 3.
It should observe whether steel band 1 is pulled out according to the reaction of steel band 1 at this time, judge whether probe 4 divides with 3 bottom of casing
From if do not separated, then being changed to injection mode again will the 4 downward injection of continuation of probe.It, will after confirmation probe 4 is separated with casing
Casing 3 extracts a distance upwards, and loose bolt removes steel plate, successively removes casing 3 section by section by side openings end, move away from and pass through
Enter host, fiber grating 12 is connect with fiber grating demodulation device.
Step 5: the exposed steel band 1 in earth's surface, steel band are protected with the intermediate prismatic table shape protective platform 21 with anti-guard aperture
1 passes through the anti-guard aperture of steel band, and eye-catching mark is arranged at monitoring, and to prevent the disturbance to steel band 1,22 be Terrace prevention hole, such as
Shown in Figure 12.
Step 6: after the soil body around steel band restores to stablize, fiber grating demodulation device is zeroed.It then, can be real
When monitor the soil body lateral displacement.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
It is subject to the protection scope in claims.
