A kind of sand filling method compaction degree detection system and detection method thereof

Abstract

The invention relates to a system for detecting the degree of compaction of a sand filling method, which belongs to the technical field of detecting the degree of road compaction, and comprises a sand filling cylinder, a base, a soil collection box and a protective cylinder with openings at both ends. , the base is used to cut the cutting assembly on the ground, the base is provided with a driving assembly for driving the cutting assembly to make a circular motion; Digging components for digging holes. Cut out a cylindrical cutting seam through the cutting assembly; then press the casing into the cutting seam, move the position of the base so that the excavation assembly is facing the casing, and then excavate the soil in the casing through the excavation assembly effectively improve the excavation efficiency, and at the same time, the casing separates the soil around the cutting joint, preventing the excavation components from digging out the surrounding soil, resulting in over-excavation and over-excavation, and improving the accuracy of measurement.

Description

technical field [0001] The invention relates to the technical field of road compaction detection, in particular to a system and a detection method for the detection of compaction by sand filling method. Background technique [0002] The filling and compaction of the base course and surface course of roads, railways and airports all need to be tested for the degree of compaction. Among the existing testing methods, the sand filling method is the most widely used. Based on the strict control of the quality of compaction to ensure the quality of the project, the current code has higher requirements for the frequency of compaction testing. [0003] In engineering practice, compaction testing is often a labor-intensive project for testing personnel. During the peak season of subgrade construction, a large number of testing personnel are required to be stationed on site for testing. On-site manual digging, sand filling, sand recovery, and burning of moisture content, etc. A serie...

AI Technical Summary

Problems solved by technology

This is very detrimental to the control of the quality of earthwork filling. Due to insufficient detection, the unqualified filling and compaction projects will pass the acceptance inspection, which will lead to a series of problems such as sedimentation and cracking during the operation of the project, which will seriously shorten the actual service life of the project. , causing adverse social impact

And as my country's engineering construction attaches great importance to quality issues and requires the standardization of construction processes, the backward on-site manual inspection methods at this stage are far from meeting the needs

[0004] Among them, manual digging takes the longest time, because the compactness of the subgrade soil layer after being compacted is relatively high, time-consuming and labor-intensive when digging holes, and the efficiency is very low
