Pavement base compactness detection equipment capable of filling detected part

Abstract

The invention, which relates to the technical field of pavement compactness detection, discloses pavement base compactness detection equipment capable of filling a detected part. The equipment comprises a shell; a hollow channel is fixedly connected to the interior of the shell; and an extrusion mechanism is movably connected to the inside of the hollow channel. A sample groove is fixedly connected to the left side of the hollow channel. A rotating plate is movably connected to the right side of the hollow channel; and a supply box is fixedly connected to the surface of the rotating plate. A drill bit is movably connected to the lower end of the hollow channel. When the drill bit finishes drilling and moves upwards, a reset spring resets and pulls a guide wheel downward; gas in an air bagcan be released; and repairing liquid in a layering box is extruded out, so that a sample is taken out and is repaired. When the repairing liquid in the layering box is completely released, a base material entering a discharging opening pushes the rotating plate to move upwards and extrudes the repairing liquid in the supply box, so that the supplying for the layering box is realized.

Description

technical field [0001] The invention relates to the technical field of pavement compaction detection, in particular to a pavement base compaction detection device for filling the detected parts. Background technique [0002] Municipal engineering construction supervision and quality inspection, which includes municipal engineering quality assessment methods, on-site quality inspection of roadbed and pavement, quality inspection of concrete components, integrity inspection of foundation piles, etc., among which road surface quality inspection is the research object of the present invention. [0003] There are many types of objects for pavement quality testing, among which it is more important to test the degree of compaction of the road surface; the degree of compaction, also known as the degree of compaction, refers to the dry density and the standard maximum dry density of soil or other road construction materials after compaction The ratio of the degree of compaction is ex...

AI Technical Summary

Problems solved by technology

[0004] With the development of highway construction in our country, the demand for devices to quickly detect the degree of compaction is also increasing. However, the traditional way of detecting the degree of compaction is very complicated, and it is necessary to manually drill holes on the base layer to take samples, and the samples taken out are mixed in the At the same time, it cannot be divided according to different depths; in addition, after the excavated subgrade filling will leave a cavity on the ground, it needs to be repaired with separate equipment later, and the repair instrument cannot accurately locate the excavated part, resulting in repair The effect is not good, so a kind of pavement base compaction detection equipment that fills the detected part came into being
