Description
Technical field
The utility model relates to the constructions of subway slurry shield tunnel, are especially for subway slurry shield interval measure
Buckle-type point device.
Background technique
It in subway slurry shield tunnel work progress, needs securely to be arranged interim measurement point, carries out elevation and plane
The setting-out of construction survey works.
Currently, the setting of above-mentioned interim measurement point generallys use two ways: 1, using electric drill in section of jurisdiction bottom inverted arch
Locate perforating, and be implanted into the cylindrical steel ingot with crosshair or survey nail, waits after consolidation as the interim of elevation and plane survey
Point.2, use paraffin pen mark mark signature mark as interim site setting on battery truck traveling steel rail in tunnel.The first side
Deficiency existing for formula is: manually being drilled using electric drill, when bore position encounters tunnel segment structure reinforcing bar, hole depth is difficult to
It is up to standard, cause point not to be available and needs to look for position to layout again；And when burying the position of point too close to section of jurisdiction bottom,
Point can be buried when occurring muddy water in tunnel, cause point not to be available, measure work and can not carry out；Meanwhile the point
It needs to carry out that point is pulled out and hole concrete fills up repair after use, and restores that difficulty is larger, processing is difficult.Second of side
Deficiency existing for formula is: using paraffin pen in rail surface mark mark signature silk mark point, the strength that mark draws mark is different
There is deviation in the centering work that will lead to measuring instrument；Special messenger is needed to hold flashlight to point crosshair during Point Measurement centering
It is illuminated；It exists simultaneously point mark and streaks and shallowly lead to not the defect that accurately survey of progress point is set excessively in coarse, trace.
Summary of the invention
The utility model aim is to provide a kind of buckle-type point device for subway slurry shield interval measure, realizes spirit
Living, quick, secured setting elevation and plane interim measurement point.
To achieve the above object, the utility model takes following technical proposals:
Buckle-type point device described in the utility model for subway slurry shield interval measure, including benchmark buckle, institute
It states benchmark buckle and door shape composed by first vertical plate at the transverse slat both ends, the second vertical plate is set as transverse slat, vertically downward
Structure；First vertical plate top is connect by connecting bolt with transverse slat, and fastening bolt is provided in the middle part of the first vertical plate, described
Second vertical plate is structure as a whole with transverse slat；A bit flag is provided on transverse slat, described bit flag includes being arranged in vertically upward
The cylinder of transverse slat upper face offers crosshair markings in the cylinder top surface.
The cylinder is cylindrical body, and the top surface of the cylindrical body is hemisphere face, and the crosshair markings are provided with described
Hemispherical middle part.
Side on the transverse slat positioned at described bit flag is provided with the lighting device with electric switch, the illumination
The headlamp of device is arranged towards bit flag side.
The lower edge of first vertical plate is the tilted plate section extended to inclination on the inside of door shape, and the tilted plate section and first stand
Angle between plate is 135o.
The lower edge of second vertical plate is to horizontal-extending turnup structure on the inside of door shape.
The utility model advantage is to aim at the elevation in subway slurry shield section and plane construction survey and design.Due to
It is carried out when shield machine and battery locomotive remain static when the utility model is based on construction survey operation, therefore point
Device is in stable state on rail, and height is moderate and will not be buried by muddy water or ponding, works convenient for the centering of measuring instrument
It carries out and the survey of elevation point is set；This point device carries auxiliary type automatic illuminating equipment, during measuring instrument and setting up, beats
Light switch is opened, point device crosshair markings center can be illuminated, artificial light link is eliminated, centering work is greatly saved
The time of work, to realize flexible, quick, secured setting elevation and plane interim measurement point.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of point device described in the utility model.
Fig. 2 is the overlooking structure diagram of Fig. 1.
Specific embodiment
