Description
Technical field
The invention belongs to geotechnical investigation technical fields, and in particular to the exploration of roadbed collapsibility in a kind of geotechnical engineering
Device.
Background technology
Collapsible loess is very wide in distribution in China, accounts for about the 4.9% of world's loess distribution gross area；The main feature of loess
It is that hole big, short texture, mechanical strength are poor, therefore Collapsing Deformation easily occurs under the conditions of immersion, engineering is caused seriously
Harm, the soil body occurs significant unexpected when engineering problem outstanding is immersion under upper overburden layer gravity pressure or under additonal pressure
Sedimentation causes superstructure or facility to be destroyed.
It is safe and reliable, economical to prevent the generation of foundation instability accident when Collapsible Loess District carries out construction project
Reasonably carry out engineering design, construction, it is necessary to be commented with engine request, the collapsibility for carrying out loess according to the characteristics of collapsible loess
Valence.
Assessment of loess collapsibility relies primarily on laboratory test after on-the-spot test and sampling.For the method for laboratory test,
Since loess has inhomogeneities, even if bigger if sampling the result difference of experiment on same place, same soil layer, examination
It is also bigger to test error；The sample point arranged when prospecting is generally all relatively more, and quantity of sampling quantity is also bigger, therefore sampling test is sentenced
The collapsibility for determining loess is the work of a burdensome；Therefore common that on-the-spot test, indoor examination are carried out to Collapsing Deformation of Loess
It tests for supplementing.
In the prior art, 201210116539.4 patent of invention proposes a kind of test for the exploration of soil layer collapsibility
Device pierces soil layer by using probe, is located at the water filling device in test device to probe positions water filling, reaches full
With the variation for front and back intensity of soaking by comparing the soil body judges the collapsibility of soil layer.But the exploration device in the invention,
Popping one's head in, sectional area is equal with casing outer barrel outer diameter, and the water of injection is flowed down along casing outer barrel, causes the water that lower part is injected too many, leads
Cause short time water filling uneven, error is too big to make the effect of detection distinguish, and the result obtained is inaccurate.
Invention content
Purpose of the present invention is to：It is intended to provide a kind of exploration device of roadbed collapsibility in geotechnical engineering, it is existing for solving
