Abstract
The utility model relates to the technical field of municipal engineering, belongs to measurement instruments used in road construction and discloses a road structure thickness tester. The road structure thickness tester comprises a probe rack and a locating plate and is characterized in that two probes are installed on the probe rack, corresponding guide holes are formed in the locating plate, and the probes are respectively placed in the guide holes; a columnar ruler is installed on the locating plate, the columnar ruler is in slide connection with the probe rack through a slide way hole formed in the probe rack, a ruler block is arranged at the upper end of the columnar ruler, and a ruler block groove is formed in the upper part of the probe rack. The road structure thickness tester disclosed by the utility model has the advantages of reasonable structure and convenient use and is hardly affected by the flatness of a road base layer so as to ensure high measurement precision.
Description
Technical field
The utility model relates to municipal engineering technical field, and the apparatus of the measurement road structural thickness using while belonging to town road construction, is a kind of road structure calibrator.
Background technology
In town road work progress, need to measure the thickness of road structure, the measuring method of conventional road structure thickness is at present: hand digging exposes after section, use common ruler to measure, have the larger and lower shortcoming of certainty of measurement of the damage area of deck, and labour intensity is larger.Application number is that 200520104913.4 Chinese utility model patent discloses a kind of pitch-road-face loosepaving thickness measuring instrument, comprises base and detects pin, can when road construction, detect by the loose laying depth to flexible pavement.Existence can only be carried out the deficiency of spot measurement, is sometimes subject to the impact of road surface partial bottom Base Smoothness, and certainty of measurement is lower.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, the road structure calibrator using when a kind of road construction is provided.
The purpose of this utility model is achieved through the following technical solutions: road structure calibrator, comprise probe carriage and location-plate, it is characterized in that: two probes are installed on probe carriage, on location-plate, be provided with two corresponding pilot holes, and the probe of installing on probe carriage is placed on respectively in the corresponding pilot hole arranging on location-plate; The lower end of probe is provided with wedge-like sword; Column chi is installed on location-plate, on column chi, is provided with scale, column chi is slidably connected by skidway hole and the probe carriage being arranged on probe carriage, and the upper end of column chi is provided with chi gear, and the top of probe carriage is provided with chi retaining groove.
The utlity model has advantage rational in infrastructure and easy to use, be subject to the impact of road subbase course planeness smaller, certainty of measurement is higher.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
In figure, 1 chi keeps off 2 probe 3 probe carriage 4 column chi 5 location-plate 6 pilot holes
The specific embodiment
The technical scheme of embodiment of the present utility model is such: road structure calibrator, comprise probe carriage 3 and location-plate 5, it is characterized in that: two probes 2 are installed on probe carriage 3, on location-plate 5, be provided with two corresponding pilot holes, and the probe 2 of installing on probe carriage 3 is placed on respectively in the corresponding pilot hole 6 arranging on location-plate 5; The lower end of probe 2 is provided with wedge-like sword; Column chi 4 is installed on location-plate 5, on column chi 4, is provided with scale, column chi 4 is slidably connected by skidway hole and the probe carriage 3 being arranged on probe carriage 3, and the upper end of column chi 4 is provided with chi gear 1, and the top of probe carriage 3 is provided with chi retaining groove.
During use, place after location-plate 5 of the present utility model on test point, press down probe carriage 3, make the sub-layer end face at the bottom of two probes 2 are inserted into deck, the scale showing after column chi 4 rises is the virtual resurfacing thickness of this deck.
