Abstract
The utility model discloses a two-sided measuring target mark, which comprises a concrete block, tapetum lucidums and a steel rod, wherein, the tapetum lucidums are respectively adhered to the side faces of both right-angle sides of the concrete block; one end of the steel rod is molded into the concrete block and the other end is anchored and laid underground. The utility model is characterized by simple structure, convenient operation, keeping better continuity of deformation observation numerical value of measuring point to avoid measuring point deformation loss in conventional target mark observation.
Description
Technical field:
The utility model relates to Geotechnical Engineering, more specifically relates to a kind of two-sided engineering survey target.
Background technology:
Carry out three-dimensional noncontact deformation measurement at underground workshop and tunnel with total powerstation, the routine measurement target is made up of steel pole, sheet steel and the retroreflective sheeting that is attached on the sheet steel usually.When burying measurement target drone underground, bore aperture on rock mass (or structures) surface earlier, then the steel pole on the measurement target drone is inserted wherein, treat just can observe after the anchoring agent is solidified in the hole measurement target drone.Suffer the destruction of blasting flyrock during the measurement target drone construction and excavation easily: retroreflective sheeting is ruined or sheet steel is departed from the origin-location by bump.The reparation of measurement target drone and rearrange and need the regular hour makes the observation of this measuring point can not keep continuity, and there is deformation loss in measuring point, and the measuring point observation value can not reflect the true strain of measuring point.
Summary of the invention:
The purpose of this utility model is to be to provide a kind of two-sided measurement target drone, substitutes the routine measurement target, and is simple in structure, easy to operate, guaranteed the continuity of measuring point observation, and observation value has truly reflected the distortion situation of this measuring point.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of measurement target drone is made up of concret block, steel pole, retroreflective sheeting.The horizontal cross-section of concret block is an isosceles right triangle, and retroreflective sheeting is attached to the side of two right-angle sides on the concret block respectively, and the part of steel pole is cast in the concret block, and another part of steel pole is used to cooperate the sand-cement slurry anchoring to bury use underground.
Using method of the present utility model is: after burying measurement target drone underground predetermined measuring point, simultaneously two place's retroreflective sheetings of measurement target drone are all observed, and the observation value record is put on record; The blasting flyrock that construction and excavation produces often can only destroy the retroreflective sheeting of a certain side, and the observation value of the retroreflective sheeting of opposite side guarantees that then there is not loss in this measuring point distortion numerical value; When having construction and excavation to disturb, new retroreflective sheeting is not replaced ruined retroreflective sheeting at last.
The utility model compared with prior art has the following advantages: the observation value of this measuring point obtains backup, and there is not loss in the distortion numerical value of measuring point during construction and excavation, and the distortion numerical value of measuring point keeps continuity, can truly reflect the distortion situation of measuring point.
Description of drawings:
Fig. 1 is a kind of two-sided measurement target drone structure schematic top plan view.
Fig. 2 is a kind of two-sided measurement target drone structural representation.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described in further detail:
According to Fig. 1, Fig. 2 as can be known, retroreflective sheeting 2 is glued the side that is attached to two right-angle sides on the concret block 1 respectively by self-contained viscose glue, make retroreflective sheeting 2 fixing on concret block 1, one end of steel pole 3 is cast in 1 li of concret block, make steel pole 3 fixing on concret block 1, the other end anchoring of steel pole 3 is buried underground, is to bury underground in the small bore on rock mass (or structures) surface by the mode of sand-cement slurry anchoring, makes steel pole 3 fixing on rock mass (or structures) surface.After burying measurement target drone underground predetermined measuring point, simultaneously two place's retroreflective sheetings of measurement target drone are all observed, and the observation value record is put on record; The blasting flyrock that construction and excavation produces often can only destroy the retroreflective sheeting of a certain side, and the observation value of the retroreflective sheeting of opposite side guarantees that then there is not loss in this measuring point distortion numerical value; When having construction and excavation to disturb, new retroreflective sheeting is not replaced ruined retroreflective sheeting at last.
