The site measuring device is formed by connecting a main ruler and a secondary ruler; the main ruler is formed by connecting more than two main ruler sections having fixed length into one body along the length direction by mutually matched locating pins and locating holes; the secondary ruler is matched and connected with the tail end of the main ruler by the locating pins and the locating holes; a vernier scale is sleeved on a scale plate of the secondary ruler; and a measuring pin vertical to the length direction is fixed on the first section of the main ruler and the vernier scale, respectively. According to the site measuring device for detecting deformation of road materials, requirements of wide range and high precision in detecting deformation of road materials are met; and the site measuring device is convenient to use, simple structure, easy to manufacture, and capable of better meeting the monitoring and detecting requirements for the road surfaces.
Description
Technical field
The invention belongs to the civil engineering field of measuring technique, particularly a kind ofly be used for detecting the device that ground surface material is out of shape in construction and military service process.
Background technology
Survey tool in civil engineering and the geography information generally has than large scale, adopts transit, total powerstation, laser range finder etc. usually, can measure several kilometers, several meters yardstick, and general precision is up to the mm level; Survey tool in the mechanical engineering then has than small scale, often adopts Steel Ruler, slide measure, spiral micrometer etc., and general precision is up to μ m level.
In the construction and maintenance processes of pavement of road; Need the distortion in road pavement forming materials process and the use accurately to measure, the expansion that causes in environmental temperature fluctuation at contraction, cement pavement and the flexible pavement of cooling procedure like: the contraction of the cement concrete pavement hardening process of newly building, new black top compound road surface and the length of contraction, patching material and ground surface material contract and mate etc.The characteristics of its measurement are: certainty of measurement is had relatively high expectations (the for example little temperature difference cause < the length amount of contracting of 0.1mm, precision is near the mechanical engineering certainty of measurement), range is crossed over big (several meters and tens of rice long), measured yardstick single (generally only surveying the variable in distance of point-to-point transmission).Measurement that can be through the road pavement material deformation, inverting road surface stress state under various conditions is for the construction and maintenance technology on road surface provides basic theoretical foundation.In the face of the measurement in pavement of road making, deck paving and road surface and the bridge floor repairing, above-mentioned existing all kinds of measurement measurers all can not address that need preferably.Need research and develop a kind of measurement mechanism that is specifically designed to the construction and the maintenance of pavement of road, it has the characteristics than wide range, degree of precision for this reason.
Summary of the invention
The field measurement apparatus that the purpose of this invention is to provide a kind of ground surface material distortion can satisfy construction and the wide range of maintenance measurement and the requirement of high accuracy two aspects of pavement of road.
Realize that the technical scheme that above-mentioned purpose of the present invention is taked is: measurement mechanism is formed by connecting main scale and secondary chi; Main scale is the main scale sections of regular length more than two sections; Cooperate through alignment pin and locating hole each other and fuse along its length; Secondary chi is connected terminal in main scale through alignment pin and locating hole, be with vernier scale on the scale plate of secondary chi, fixes a survey pin vertical with length direction on first section of main scale and the vernier scale respectively.
Between the main scale sections and the alignment pin between main scale sections and the secondary chi and locating hole link position be provided with screwed hole, through screwed hole with location conehead screw lock on alignment pin.
Vernier scale gauge head on the secondary chi adopts the electronic digital display vernier, and calibration is 1mm on the secondary chi scale plate, and the calibration on the main scale is 1cm.
During use the survey toe end contraposition of main scale end gauge head is fixed in the preset holes of survey mark (or presetting cross and star center); The slip vernier makes vernier scale survey the preset holes interior (or presetting cross and star center) that another survey mark is fixed in the pin contraposition; Read the measured value of main scale and secondary chi then respectively, just can obtain The ultimate results by two measured value additions.
The invention has the beneficial effects as follows: taken into account the requirement of wide range and high accuracy two aspects, easy to use, simple structure, be easy to processing and fabricating, can satisfy the monitoring and detection of pavement of road preferably.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Each label is among the figure: main scale termination 1, location cone-head screw 2, main scale sections 3, secondary chi connector 4, vernier scale 5, scale plate 6, survey pin 7, alignment pin 8, screwed hole 9, locating hole 10, survey mark preset holes 11.
The specific embodiment
Referring to Fig. 1, this measurement mechanism is formed by connecting main scale and secondary chi.The head end of main scale is main scale termination 1; Be connected with locating hole 10 on the main scale sections 3 through alignment pin 8; Also cooperate between the main scale sections 3 of each section regular length through alignment pin 8 and locating hole 10; Fuse along its length, the bottom of main scale termination 1 is fixed with the survey pin 7 vertical with the chi length direction.Secondary chi is by secondary chi connector 4, vernier scale 5, scale plate 6 and survey pin 7 four parts and forms, and secondary chi connector 4 is connected in latter end main scale sections 3 through alignment pin 8 and locating hole 10, is with vernier scale 5 on the scale plate 6 of secondary chi.Be provided with screwed hole 9 at each alignment pin 8 and locating hole 10 link positions, be locked on the alignment pin 8, be shifted in avoiding the use of or come off through screwed hole 9 usefulness location cone-head screw 2.Vernier scale 5 gauge heads on the secondary chi can adopt the electronic digital display vernier, so that the reading of in-site measurement value, 1mm on the secondary chi scale plate 6, the calibration on the main scale are 1cm.The range of main scale splicing length decision measurement mechanism generally is no more than 12m according to the needs of the deformation measurement of ground surface material, and the measured value of main scale and secondary chi comprehensively is an actual measured value, reaches as high as 0.005mm like its precision of employing high-precision electronic vernier.
During use the survey pin 7 most advanced and sophisticated contrapositions of main scale termination 1 are fixed in the survey mark preset holes 11 (or presetting cross and star center); Slip vernier scale 5 is fixed in another survey mark preset holes 11 (or presetting cross and star center) survey pin 7 contrapositions of vernier scale 5; Read the measured value of main scale and secondary chi then respectively, just can obtain The ultimate results by two measured value additions.
