Device.
Background technology
Collapsible loess is very wide in distribution in China, accounts for the 4.9% of world's loess distribution gross area；The main feature of loess
It is poor hole big, short texture, mechanical strength, therefore Collapsing Deformation easily occurs under the conditions of immersion, engineering is caused seriously
Harm, the soil body occurs significant unexpected when prominent engineering problem is immersion under upper overburden layer gravity pressure or under additonal pressure
Sedimentation, causes superstructure or facility to destroy.
When Collapsible Loess District carries out construction project, to prevent the generation of foundation instability accident, safe and reliable, economy
Reasonably carry out engineering design, construction, it is necessary to which according to the characteristics of collapsible loess and engine request, the settlement by soaking for carrying out loess is commented
Valency.
Assessment of loess collapsibility relies primarily on laboratory test after on-the-spot test and sampling.For the method for laboratory test,
Because loess has inhomogeneities, even if being sampled on same place, same soil layer, the result difference of experiment is also than larger, examination
Error is tested also than larger；The sample point arranged during prospecting typically all compares many, and quantity of sampling quantity is also than larger, therefore sampling test is sentenced
The settlement by soaking for determining loess is a job for burdensome；Therefore it is conventional that on-the-spot test, indoor examination are carried out to Collapsing Deformation of Loess
Test for supplementing.
In the prior art, 201210116539.4 patent of invention proposes a kind of test for the exploration of soil layer settlement by soaking
Device, it pierces soil layer by using probe, and the water filling device in test device is reached full to probe positions water filling
With, by compare the soil body soak before and after intensity change, judge soil layer settlement by soaking.But, the exploration device in the invention, its
Probe sectional area is equal with sleeve pipe outer barrel external diameter, and the water of injection is flowed down along sleeve pipe outer barrel, and the water for causing bottom to inject is too many, leads
Cause short time water filling uneven, so that the effect difference error of detection is too big, the result for drawing is inaccurate.
The content of the invention
The present invention seeks to：A kind of exploration device of roadbed settlement by soaking in Geotechnical Engineering is aimed to provide, it is existing for solving
Skill intraoperative porbe sectional area is equal with sleeve pipe outer barrel external diameter, and the water of injection is flowed down along sleeve pipe outer barrel, the water for causing bottom to inject
