Description
Technical field
The utility model relates to a kind of soil body testing arrangement, relates to a kind of Portable Automatic penetrometer that soil body engineering properties is carried out in-situ test specifically.
Background technology
In the middle of geotechnical investigation, need to measure each soil layer mechanics index of physics, for engineering design provides reference and foundation.The drill hole sampling process change the natural stress state of the soil body, the soil body mechanics index of physics distortion in a way that the various disturbances that in sampling, transportation, sample making course, cause cause laboratory tests to obtain.Static sounding is particularly useful for being difficult for the saturated sand of sampling and the prospecting on highly sensitive bury stratum as a kind of effective home position testing method; Penetrometer is as a kind of miniature static sounding equipment; Through the test of specific penetration resistance, can obtain the various mechanics index of physics such as compactness, bearing capacity of foundation soil of relevant soil layer.The used injection equipment of ground observation heavy, operation inconvenience, be not suitable for small scale soil strengths such as indoor model test in real time, fast, accurately measure.Existing portable soil penetrometer adopts the artificial injection of hand-held, wayward injection speed, and be prone in the test process produce rock, influence measuring accuracy.Therefore, the penetrometer that a kind ofly has higher measuring accuracy, is easy to carry, indoor model test and open-air shallow-layer bury property detection are had good applicability is very necessary.
Summary of the invention
The utility model provides a kind of Portable Automatic penetrometer that is applicable to indoor model test, open-air shallow-layer bury character in-situ test, to overcome the deficiency of prior art.
The technical scheme that the utility model adopted: a kind of Portable Automatic penetrometer; Comprise injection feeler lever, feeler lever, the automatic acquisition device that links to each other with pressure sensor, spacing card and be fixed in two control cabinets on the crossbeam; It is characterized in that: also comprise the drive link that passes through control cabinet; This drive link is the screw thread that a rectangle and a side have the band rule; The lower end of drive link connects feeler lever or injection feeler lever, is positioned at coaxial fixed conveyor wheel on the main shaft of the inner reductor of control cabinet, is meshing with each other through screw thread between this drive and the drive link.
Above-mentioned pressure sensor is embedded into the lower end of drive link, and is positioned at control cabinet.
Compared with present technology, the advantage of the utility model is: drive drive and then drive drive link through reductor and realized adjustable to the uniform and automatic injection of the soil body and injection speed.The drive link bottom gets pressure sensor and the automated collection systems that is attached thereto has been realized test and record to penetration resistance through being embedded into, and has higher measuring accuracy.Crossbeam both can set up and be fixed on the real-time testing of soil mass property in all kinds of indoor model tests such as realizing flume test on the tank, also can be applicable to the in site measurement of open-air superficial part bury character.The control cabinet volume is little, and whole system shortage in weight 10kg has good portability.
Description of drawings
Fig. 1 is the general structure sketch map of the utility model.
Among the figure: 1-injection feeler lever; The 2-feeler lever; The spacing card of 3-; The 4-control cabinet; The 5-drive link; The 6-crossbeam; The 7-pressure sensor; The 8-drive; The 9-reductor; The screw thread of 10-band rule.
The specific embodiment
As shown in Figure 1; A kind of Portable Automatic penetrometer; Comprise injection feeler lever 1, feeler lever 2, the acquisition system (omitting among the figure), the spacing card 3 that link to each other with pressure sensor 7 and be fixed in two control cabinets 4 on the crossbeam 6; It is characterized in that: also comprise the drive link 5 that passes through control cabinet 4, this drive link 5 is the screw thread 10 that a rectangle and a side have the band rule, and the lower end of drive link 5 connects feeler lever 2 or injection feeler lever 1; Be positioned at coaxial fixed conveyor wheel 8 on the main shaft of the inner reductor 9 of control cabinet 4, be meshing with each other through screw thread between this drive 8 and the drive link 5.Said pressure sensor 7 is embedded into the lower end of drive link 5, and is positioned at control cabinet 4.
Consider the adjusting depth of penetration, connect at least one feeler lever 2 on the injection feeler lever 1 of the utility model, sliceable dismounting is to regulate length overall between a plurality of feeler levers 2; The upper end of feeler lever 2 is connected with drive link 5; Drive link 5 is a rectangle, and the one of which side has the screw thread 10 of band rule, in order to the current depth of penetration of direct demonstration.Two spacing cards 3 are used for limiting the horizontal jitter of drive link 5 up and down.Reductor 9 and drive 8 is coaxial fixing, and drive 8 edges are threaded and are meshing with each other with the screw thread of drive link 5, can drive drive links 5 and then drive the at the uniform velocity injection that feeler lever 2 and injection feeler lever 1 are realized the soil body through reductor 9; Regulate reductor 9 rotating speed adjustable joint injection speed.Be embedded into the pressure sensor 7 of drive link 5 lower ends and the acquisition system that is attached thereto, but real-time testing and record penetration resistance; Pressure sensor 7 is positioned at the below of spacing card 3, and the error of having avoided mechanical friction to cause has improved measuring accuracy.Crossbeam 6 is positioned under the control cabinet 4, with convenient displacement and fixing.
