Integrally swelled with frost wall, cause surface uplift to ftracture, potential safety hazard is brought to earth's surface building.Therefore in mortar depositing construction process
In, horizontal displacement monitoring need to be carried out on each tube coupling that may be influenceed by slip casting.At present, horizontal displacement monitoring mainly by by
Measuring instrument（Theodolite, spirit level, rangefinder, total powerstation etc.）Carry out the change of measurement angle, the length of side and elevation and then determine to become
Shape amount, general measuring method mainly include precise traversing method, intersection, total powerstation 3 d deformation monitoring etc., pipe curtain tube coupling
Interior narrow space, it is more difficult to tube coupling progress horizontal displacement monitoring by measuring instrument, and apparatus measures are to external ambient light
Line requires higher, and tube coupling internal light condition is poor, and measurement accuracy can not be guaranteed.In addition, construction period is to tube coupling water
Flat displacement monitoring timeliness demand is higher, and by relatively long the time required to apparatus measures.In summary, general measuring method without
Method meets the tube coupling horizontal displacement monitoring under the conditions of pipe curtain advance support, therefore needs a kind of monitoring device of invention badly to meet the operating mode
Down tube horizontal displacement monitoring demand.
The content of the invention
The utility model is directed to because tube coupling narrow space, monitoring accuracy and timeliness demand are higher, and conventional levels displacement is surveyed
A kind of the problem of amount method can not meet to have pipe curtain supporting condition down tube horizontal displacement monitoring etc., there is provided operating mode down tube
Horizontal displacement monitor is narrow and small with tube coupling inner space during solving the problems, such as monitoring, while reduces external environmental interference,
Measurement accuracy is improved, enhancing is ageing, effectively reduces construction cost.
Realize that the technical scheme of above-mentioned purpose of utility model is to provide tube coupling horizontal position under the conditions of a kind of pipe curtain advance support
Move monitoring device, including fastener and steel wire；Fastener for fixing steel wire is arranged on the both ends of steel wire, and steel is set on steel wire
Steel wire measuring point is marked, and tube wall measuring point is provided with the tube wall of tube coupling junction to be monitored and is marked, and steel wire measuring point mark is surveyed with tube wall
Point mark is correspondingly arranged, and forms one group of horizontal displacement measuring point；During monitoring, fastener is individually fixed on the tube wall of tube coupling hole and
On the tube wall to be monitored of least significant end, it is in the horizontality tightened, tube wall measuring point mark and corresponding steel wire measuring point to make steel wire
The line of mark is vertical with steel wire.
The steel wire length that the utility model is selected should be greater than slip casting length；Gauge of wire can select 0.5~1.5 mm.
During monitoring, one group of horizontal displacement measuring point is set in each tube coupling junction.
The monitoring device also includes a fastener, for racking fastener, makes steel wire exceptionally straight firm；Described fastener
It can be bolt fastener.
In the relatively-stationary tube coupling hole tube wall in position and inward can intervisibility farthest tube wall on, using the side such as welding
Method is each to fix a steel wire bolt fastener, is placed in from the mm specification wires of diameter 0.5~1.5 on two end fasteners, and make
Fastener is racked with fastener, makes steel wire exceptionally straight firm, in this, as datum line.Connect there is the tube coupling for being subjected to displacement trend side
Meet place and tube coupling horizontal displacement measuring point mark is set, mark is set simultaneously on corresponding steel wire, and make tube wall and steel wire subscript
The line of note is substantially vertical with steel wire.The mark on mark and corresponding steel wire on tube wall forms one group of horizontal displacement and surveyed
Point, each tube coupling junction all should set one group of horizontal displacement measuring point, by measuring measuring point distance change, to tube coupling horizontal displacement
It is monitored.
In the prior art, horizontal displacement monitoring is mainly by by measuring instrument（Theodolite, spirit level, rangefinder, whole station
Instrument etc.）Carry out the change of measurement angle, the length of side and elevation and then determine deflection.General measuring method mainly includes precision traverse and surveyed
Amount method, intersection, total powerstation 3 d deformation monitoring etc..Narrow space in pipe curtain tube coupling, water-filling is entered to tube coupling by measuring instrument
Flat displacement monitoring is more difficult, and apparatus measures require higher to outside ambient light, and tube coupling internal light condition is poor, surveys
Accuracy of measurement can not be guaranteed.In addition, construction period is higher to tube coupling horizontal displacement monitoring timeliness demand, and pass through apparatus measures
Required time is relatively long, ageing poor.
Compared with prior art, the utility model has the advantages that：It is relatively-stationary by the way that steel wire is fastened on into end positions
Datum line is used as at bolt fastener, sets horizontal displacement to mark on tube coupling junction and corresponding steel wire and forms one group
Horizontal displacement measuring point, and monitor tube coupling horizontal displacement by measuring measuring point distance.Pass through the tube coupling water that the utility model is related to
Flat displacement monitor, the problem of tube coupling inner space can be overcome narrow and small, and do not constrained by light condition, external environment influences
Smaller, measurement accuracy is higher.During tube coupling horizontal displacement monitoring, measuring method is simple, measurement the time required to it is shorter, it is ageing compared with
By force, monitoring in real time can be achieved.In addition, the measuring instrument that routine monitoring method is relied on is mostly expensive, and the utility model
The horizontal displacement monitoring device being related to effectively reduces construction cost without using instrument.
