Abstract
The present invention provides a kind of full flowing penetrometers of float for fishing shape probe, belong to construction project technical field.The full flowing penetrometer is mainly made of float for fishing shape probe, rigid thin rod, cylindrical metal shell, pressure sensor and pedestal.The soil body lower for intensity, conventional T-bar can form stagnant area on the top of probe when extracted, flow the soil body can not on the surface of probe entirely, have an impact to test result.Therefore, it is popped one's head in using float for fishing shape, since its end is arc-shaped, on the surface of probe full flowing occurs for the soil body when penetrometer can be enable to extract, and improves the accuracy of test, simultaneously, the test for carrying out soil strength using the penetrometer is simple and convenient, can greatly shorten experiment process and test period.
Description
Technical field
The invention belongs to construction project technical fields, are related to a kind of full flowing penetrometer of float for fishing shape probe.
Background technique
Full flowing penetrometer is the novel strength test element of one kind of rising in recent years, at home and abroad the original of clayey soil
It is widely used in bit test and the test of geo- textile technique soil sample.It, which has, does not need amendment burden pressure, can be with
Soil body continuous shear stress intensity is obtained, and there are stringent Plastic Solution and warps since flow mechanism complete in penetration process makes it
Cross the advantages that circulation penetration test can be quickly obtained soft clay remodeling resistance.It is generally adopted by spheric probe either cylinder
Body probe.By that will pop one's head in, injection can obtain its initial penetration resistance into the soil body to be measured, can be obtained by extracting in the soil body
Its initial pull-out resistance, and it can be obtained by the injection and extraction of circulation and remold penetration resistance, the spirit of the soil body is evaluated with this
Sensitivity.The soil body lower for intensity, the soil body can flow entirely in detecting head surface in penetration process, and acquisition is more accurately passed through
Enter resistance, but when extracted since soil strength is smaller, leads to the stagnant area that there can be a part on the top of probe, the area
Domain is not covered by the soil body, that is, thinks that in detecting head surface full flowing does not occur for the soil body during extraction, this is for soil
Body pull-out resistance and the measurement result for remolding resistance can have a huge impact, and then will affect the estimation of Soil Sensitivity.
Summary of the invention
The present invention provides a kind of full flowing penetrometers of float for fishing shape probe, and overcoming causes since soil strength is lower
There is stagnant area in probe top, and full flow effect soil strength test accuracy cannot occur.The present apparatus is by using float for fishing shape
Probe, enable to test the soil body in extraction and cyclic process compared with the low-intensity soil body on the surface of probe and full flowing occur, from
And improve the accuracy of test result.
Technical solution of the present invention:
A kind of full flowing penetrometer of float for fishing shape probe, this flow full penetrometer include float for fishing shape pop one's head in 1, rigid thin rod 2,
Cylindrical metal shell 3, pressure sensor 6 and pedestal 7；2 one end of rigid thin rod is threadedly coupled with float for fishing shape probe 1, the other end
It is connect by bolt 4 with pressure sensor 6；One layer of cylindrical metal shell 3 is cased with outside rigid thin rod 2 and pressure sensor 6,
There are the gap of 1mm between cylindrical metal shell 3 and rigid thin rod 2, prevents the presence of friction therebetween, influence the knot of test
Fruit.3 surfaces externally and internally of cylindrical metal shell is smooth, and keeps at a distance from 1-2mm with 1 end of float for fishing shape probe；It is passed positioned at pressure
3 bottom of cylindrical metal shell of 6 end of sensor is equipped with pedestal 7, and pedestal 7 is fixed on motor；It covers outside pressure sensor 6
3 side of cylindrical metal shell fluting, the export for the external the end of a thread 5 of pressure sensor.
The material of the float for fishing shape probe 1 is aluminium.
The material of the cylindrical metal shell 3 is steel.
The pedestal 7 connect bolt 9 with pressure sensor by pedestal screw hole 8 and is fixed on motor.
When testing soil strength, motor is opened, the full flowing penetrometer for making float for fishing shape pop one's head in vertically is passed through with constant speed
Enter the soil body, penetration resistance can be transferred to pressure sensor from float for fishing shape probe by rigid thin rod, and pressure sensor is with electric signal
Form output.
Beneficial effects of the present invention: traditional T-bar is in the lower soil strength of test intensity, in extraction and cyclic process
Stagnant area can be formed on the top of probe, the soil body cannot be flowed entirely on the surface of probe, be had an impact to the result of test.
The present invention can be such that the soil body flows full during extraction and circulation on the surface of probe using float for fishing shape probe, make test
As a result more accurate.The invention simultaneously, only controls computer by operator, can realize the injection of probe, data-signal is adopted
Collection, substantially reduces test operation process and test period.

Specific embodiment
A specific embodiment of the invention is described below in conjunction with attached drawing.
In Fig. 1,2 rigidity of rigid thin rod is sufficiently large and both ends screw thread is handled, and 2 one end of rigid thin rod and float for fishing shape is made to pop one's head in
The connection of 1 end thread, the other end and pressure sensor 6 are connected by connection bolt 4, and pressure sensor 6 uses tension-compression sensor.
One layer of cylindrical metal shell 3, cylindrical metal shell 3 and rigid thin rod on 6 outer sheath of rigid thin rod 2 and pressure sensor
There are the gap of 1mm between 2, prevents from generating friction between rigid thin rod 2 and cylindrical metal shell 3, influence the accurate of test
Property.And 3 surfaces externally and internally of cylindrical metal shell is smooth, to reduce the influence of outer frictional resistance and internal friction.Cylindrical metal
