Embodiment 1

[0039] like Figure 1 to Figure 5 As shown, the present invention provides a mobile vehicle-mounted system for finely detecting underground hidden dangers in roads. The system is suitable for continuous, rapid and accurate determination of harder, thicker and deeper formations, and can be used to determine the compressive strength of rock and soil, Bearing capacity of bridge pile foundation, as well as roadbed disease diagnosis and foundation reinforcement effect evaluation; adopting micro-rotary penetrating sounding as the mainstay, combined with a small amount of drilling and static penetrating sounding, can greatly reduce the amount of drilling, shorten the construction period, and save costs. Its characteristics are as follows:

[0040] The mobile vehicle system includes a miniature rotary penetrometer 10 whose drilling parameters can be known and a static-rotary penetrometer 20 whose drilling parameters cannot be known. The combination of the two penetrometers is suitabl...

Abstract

The embodiment of the invention discloses a moving vehicle-mounted system for finely detecting road underground hidden danger. The moving vehicle-mounted system comprises a drilling tool parameter available mini rotation penetrometer and a drilling tool parameter unavailable static force-rotation penetrometer. The mini rotation penetrometer comprises a moving drill bit assembly, a data collectingmechanism, a testing and analyzing system and a moving transportation frame, wherein the testing and analyzing system is used for processing and displaying data collected by the data collecting mechanism, and the moving transportation frame bears various components of the mini rotation penetrometer. The static force-rotation penetrometer comprises a static force penetrometer, a rotation penetrometer, a vehicle body assembly for bearing the static force penetrometer and the rotation penetrometer, a control table system for collecting and analyzing the data collected by the static force penetrometer and the rotation penetrometer, and a peeping imaging instrument for displaying detected images. A detection method of the moving vehicle-mounted system comprises the step S100 of mini rotation penetrometer testing, the step S200 of static force-rotation penetrometer testing and the step S300 of checking. The moving vehicle-mounted system and the detection method are suitable for continuous, rapid and accurate measuring of road underground hidden danger fine detection for hard, thick and deep stratums.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of in-situ testing of geotechnical engineering, and in particular to a mobile vehicle-mounted system and a detection method for finely detecting underground hidden dangers in roads. Background technique [0002] As a widely used geotechnical field test, the traditional static penetration test has been gradually extended to various fields of engineering construction, and has shown its importance in more and more engineering practices. The static penetration test is suitable for soft soil, generally clay soil, silt soil, sandy soil and soil containing a small amount of gravel. The cone tip resistance measured in the test can be used to determine the soil classification and mechanical characteristic indicators through empirical formulas. As a commonly used in-situ test method, the static penetration test has the characteristics of fast speed, continuous data, good reproducibility, and...
