Abstract
The utility model relates to a thickness gauge is spread to pitch pine, including measuring the base, it is provided with I shape direction recess to measure the base surface, I shape direction recess both sides are provided with the scale, I shape direction recess upper end is provided with the end cap, the lower part of end cap is provided with the pressure handle, I shape direction recess lower extreme is provided with the rubber circle, be provided with the surveying pin in the I shape direction recess. The utility model discloses thickness gauge is spread to pitch pine through in inserting the chaining pin asphalt concrete who has paved, then reads measuring instrument and goes up the scale, utilizes the equivalent principle, and the last reading of measuring instrument is the degree of depth of chaining pin inserted part. This measuring device simple structure, portable, convenient operation, measure accurate, can the be fast accurate pine shop thickness of measuring asphalt concrete.
Description
Technical field
The utility model relates to a kind of road pavement pick-up unit, specifically, relates to a kind of pitch loose laying depth measuring instrument.
Background technology
For road engineering, bituminous concrete is last one deck of road structure layer, and its thickness and flatness directly affect the permanance of road and the comfortableness of driving, and therefore bituminous concrete paving thickness is a very important technical indicator in road construction process.Need to measure loose laying depth at any time in bituminous pavement paving process, meet designing requirement with the thickness after guaranteeing its compacting.In current on-the-spot practical operation, substantially adopt traditional Specimen Inserting Method for Determining pitch pine Pu thickness, namely in asphalt mat, insert drill rod, then determine asphalt paving thickness by the degree of depth that steel ruler measurement drill rod inserts, this method not only speed is slow, and poor accuracy.
Utility model content
For above-mentioned deficiency of the prior art, the utility model provides a kind of structure simple, easy to carry, simple operation, the pitch loose laying depth measuring instrument that measuring accuracy is high.
Technical solution adopted in the utility model is:
A kind of pitch loose laying depth measuring instrument,
Comprise measurement base, described measurement susceptor surface is provided with I shape direction recess; Described I shape direction recess both sides are provided with rule;
