Problems solved by technology

On the one hand, this method cannot guarantee the vertical insertion of the steel drill; on the other hand, the manual reading is easily affected by various external conditions, and if the measuring ruler is not accurate, it is more likely to cause inaccuracy in the measurement of loose laying thickness, which in turn leads to greater Large errors seriously affect the construction quality
In addition, this method requires multi-step operations, and even requires the cooperation of two people, which is time-consuming and laborious, and affects the construction progress
[0005] To sum up, for the construction temperature and construction thickness of asphalt pavement, at present, different measurement devices are mainly used to measure separately, and each measurement method has large technical limitations and even technical defects

Embodiment

[0049] In this embodiment, the handle cover 1 is made of rubber or plastic material, with a height of 7 cm and a bottom diameter of 10 cm. It is tightly connected with the top of the protective shell 2 through threads, and plays the role of sealing and carrying, and is detachable. The protective shell below it 2 Made of transparent plastic, the height is 85cm, the diameter of the thick tube is 10cm, the diameter of the thin tube is 5cm, and the wall thickness is 0.5cm. The power supply fixing grid and the digital display thickness gauge are installed inside it from top to bottom. Grille, digital display temperature controller fixed grid, resistor plate fixed grid and connecting wire fixed column, and there is a rectangular groove hole with a length of 10cm and a width of 0.8cm opposite to the top surface of the resistor plate fixed grid , that is, vertically move the hole 31 for the rotating axis 22 to freely move up and down in it, and the power storage box 7 is fixed in the p...

Abstract

The invention discloses a portable device and method for synchronously measuring the construction temperature and thickness of an asphalt pavement. A handle cover is installed on a protective shell, a power supply, a thickness gauge, a temperature controller and an elastic mechanism are installed in the protective shell, one end of the elastic mechanism is fixed, and the other end of the elastic mechanism is connected with a treading mechanism; one end of a rotating middle shaft penetrates through the protective shell and is connected with the elastic mechanism, and the other end is located outside the protective shell and connected with a rotating pedal. A vertical moving hole for the rotating middle shaft to move up and down is formed in the protective shell; the upper end of a resistance rod is connected with the elastic mechanism, and the lower end is connected with the upper end of a plug-type sheathed thermocouple; a resistance disc is arranged in the protective shell, is opposite to the resistance rod and is in friction contact with the resistance rod; the resistance rod, the resistance disc and the thickness gauge are connected to form a loop, the plug-type armored thermocouple is connected with the temperature controller, and the thickness gauge and the temperature controller are connected with the power supply. The asphalt pavement construction temperature and construction thickness can be measured synchronously, and measurement is stable, efficient and accurate.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement construction auxiliary equipment, in particular to a portable device and method for synchronously measuring the construction temperature and thickness of asphalt pavement. Background technique [0002] In highway asphalt pavement construction, the control of asphalt pavement construction temperature and construction thickness is very important. If the construction temperature is insufficient, the problems of paving segregation and unrealistic rolling will easily occur, and the excessive or insufficient construction thickness will also have a negative impact on the smoothness of the asphalt pavement. [0003] At present, the construction temperature of asphalt pavement is often tested by infrared thermometer, which is susceptible to interference from the distance of the target to be measured, the emissivity of the target to be measured, strong light, background light, steam, dust and smoke...
