Description
Technical field
The utility model relates to a kind of tunnel cross-section measurement chi device, can be widely used in the section survey of subway, highway, railway circular tunnel.
Background technology
Current, in various heavy construction, proportion shared by tunnel is increasing, and tunnel cross-section measurement, for detecting the deviation of construction tunnel physical location and design attitude, is used to guide tunnel piercing and the gauge terminating rear tunnel of constructing in work progress and judges to have great importance.Conventional section survey method surveys three-dimensional coordinate inside one group of tunnel for using total powerstation along vertical line direction, tunnel, recycling software simulates the sectional view of section, calculates the deviation with design attitude.This method field process amount is large, and comparatively large by external environmental interference, and interior industry process is loaded down with trivial details, when running into the work of a large amount of tunnel cross-section measurement, needs to drop into a large amount of man power and materials.
Summary of the invention
Present stage, shield structure method was widely used in constructing tunnel, circular cross section tunnel becomes the main flow in tunnel, we utilizes circular tunnel symmetrical structure, develop a set of tunnel cross-section measurement chi, dip stick be provided with level tube and measure special reflector plate, accurately dip stick can be flattened according to level tube, measure the center that special reflector plate is positioned at dip stick, accurately can determine the position of center line in tunnel according to the dip stick be erected on tunnel inner wall, the three-dimensional coordinate measuring reflector plate central point can extrapolate the three-dimensional deviation of tunnel cross-section.
Tunnel cross-section measurement chi device, is characterized in that, comprises with lower part: dip stick main body, measure special reflector plate and level tube,
Dip stick main body is the square metal bar of hollow, and two level tube difference symmetric designs, at dip stick two ends, measure special reflector plate for reflects laser, dip stick center and the special reflector plate center superposition of measurement.
Further, dip stick main body adopts middle part doubling design.
Further, dip stick two ends symmetry posts reflecting strips.

Embodiment
The utility model mainly contains following components composition:
(1) dip stick main body, be the square aluminum alloy material of hollow, weight is about 3kg, and specification is 3000*60*30mm (length and width, thick), and length can adjust according to tunnel diameter, and length should be greater than tunnel radius and be less than tunnel diameter;
(2) measure special reflector plate, section chi center and reflector plate center must inregisters.When total powerstation laser ranging, measure special reflector plate for reflects laser, during range finding, total powerstation must be measured at fine sight reflector plate center.The special reflector plate of this measurement is common measurement specialized equipment, and market has more easily been bought;
(3) level tube, two level tubes distinguish symmetric designs at dip stick two ends, for the leveling in measuring process.Level tube, with micromatic setting, ensures that level tube is parallel with dip stick main body axis;
(4) door-hinge formula doubling-up device, adopt middle part doubling design, length 1.5m after doubling, is convenient to transport and carries.Door-hinge formula doubling-up device is screwed in two half dip stick main bodys, adds and guarantees that two half dip sticks are symmetrical man-hour.This door-hinge formula doubling-up device can the bilateral symmetry of more convenient guarantee dip stick main body relative to other device (as drawing and pulling type);
(5) reflecting strips, is positioned at dip stick two ends, in dim tunnel, play warning function, is convenient to look for target and evade damage.
Be used for section survey schematic diagram below in conjunction with accompanying drawing 4 tunnel cross-section measurement chi to be described further in use procedure the utility model.
1) tunnel cross-section chi is opened, lie in tunnel wall, and ensure that tunnel wall is clean, bright and clean, carry out leveling section survey chi according to level tube, measure special reflector plate orientation admeasuring apparatus device;
2) reference mark erection total station survey reflector plate central three-dimensional coordinate in tunnel;
3) reflector plate planimetric coordinates had both been tunnel center line coordinate, and elevation coordinate deducts the distance of reflector plate center to the arch end both for center line correspondence in tunnel encircles end absolute altitude;
4) departure of tunnel cross-section at three-dimensional can be calculated according to tunnel actual measurement three-dimensional coordinate.
The section survey that can be applied to various circular tunnel of the present utility model, less by external environment condition interference, simple to operate, field operation efficiency is greatly improved, decrease the field operation time, data processing also more for convenience, is applied this device and can be improve measuring accuracy, reduce working strength, be convenient to carry out section survey on a large scale.
