Background technology
Along with the quickening of China coast development process, coat at offshore beach and carry out large area reclaiming land around sea and become coastal cities and solve
The important channel of land resource shortage.The shallow top layer generally enclosing district is new alluvial or the super soft weak soil of new hydraulic reclamation, and water content is high,
Substantially without bearing capacity, it is impossible to meet construction machinery and march into the arena requirement, therefore ground must be carried out at reinforcing before enclosing district's development & construction
Reason, using the soil of reclaiming land around sea gained as construction land, and could need to carry out settlement monitoring during stiffening basic ground,
To understand the compression situation of foundation soil, evaluate basement process consolidation effect.At present, the settlement monitoring in foundation treatment engineering
Mainly bury sedimentation plate underground on top layer, set up level gauge by tripod, manually hold up chi to obtain settlement of foundation by the way of turning station.But
There is shortcomings in the method in large area super soft foundation settlement monitoring: 1) super soft weak soil engineering properties extreme difference, without the most steady
Fixed tripod construction of platform, cannot realize settlement monitoring before super soft weak soil possesses certain bearing capacity；2) chi is manually held up to need to lean on
Nearly subsidence survey point, the disturbance to super soft weak soil will cause sedimentation plate to topple, and test extremely difficult, and there is potential safety hazard；3) big
Artificial turn of station pilot measurement in area super soft weak soil region, labor intensity is big, and inefficiency, accuracy of observation is poor, and destructible face
And drainage pipe, interference construction.

Being fixed in steel pipe top, fixing bolt vertical welding is erected on bearing by fixing bolt in bearing, external observation instrument；?
The surrounding of steel pipe is stacked earth bag and is built into observation platform.
Described sedimentation plate includes steel plate and channel-section steel, and channel-section steel is welded on steel plate, and the notch side of channel-section steel is towards reference stake.
Described levelling rod can use aluminum alloy material, levelling rod bottom sides to reserve positioning bolt hole, and fixed by bolt
On channel-section steel, described levelling rod can merogenesis, flexible, levelling rod one side with a scale is placed in the notch side of channel-section steel.
Described steel pipe can be with merogenesis, and adjacent segments steel pipe uses screw thread affixed；Described bearing is fixed in described steel pipe top by screw thread.
When ground occurs sedimentation, levelling rod sinks with sedimentation plate, is surveyed by the external observation instrument being erected on reference stake
Read the change of levelling rod scale, be the settling amount on ground top layer.
The monitoring method of this utility model device, comprises the following steps:
A () sets reference stake: steel pipe hammers the foundation soil of predeterminated position, until steel pipe bottom is placed in firm soil layer, and will weldering
The bearing having fixing bolt is fixed in steel pipe top, stacks earth bag in steel pipe surrounding and builds observation platform；
B sedimentation plate is placed in ground top layer to be measured by (), the notch side of the channel-section steel of sedimentation plate is towards reference stake, and levelling rod is with a scale
One facing to notch side, and be fixed on channel-section steel；
C () repeats step (b), be placed in by multiple sedimentation plates in the different measuring points on reference stake surrounding ground top layer；
D (), by being located on reference stake by external observation instrument stand, surveys the initial scale H reading i measuring point levelling rodi0；
E () after a time, along with the generation of settlement of foundation, sedimentation plate drives levelling rod to sink together, again surveys and reads i measuring point water
The scale H of object staffit；
F () uses Hit-Hi0Obtain the scale changing value Δ H of i measuring point levelling roditIt is the heavy of i measuring point ground top layer in during this period of time
Fall amount.
The beneficial effects of the utility model are:
The measuring point levelling rod fixed placement of this utility model device, can reduce the disturbance manually holding up chi to sedimentation plate, improves test essence
Degree；Observation instrument is set up, it is to avoid carry out the office of settlement observation because super soft weak soil Lack of support cannot set up tripod on reference stake
Limit, raising testing reliability, and set up also can realize the sight of reference stake surrounding multiple measuring point without artificial turn of station pilot measurement, an instrument
Survey, be greatly improved work efficiency, reduce cost of labor, reduce the interference to construction.This device has simple in construction, operation side
The advantage such as just, certainty of measurement is high, adaptable.This utility model effectively overcomes shortcomings present in prior art,
It is applicable to the foundation treatment engineering of various complex working condition, is with a wide range of applications.
