The feeler lever is at least provided with a connecting feeler lever body, a plurality of connecting casing pipes are sleeved on the feeler lever in the length direction, the outer diameters of the connecting casing pipes contract gradually from the position where the outer diameter is the largest in the direction of the probe until being equal to the outer diameter of the feeler lever, the connecting feeler lever body is inserted into the connecting casing pipe and is contacted with the outer wall of the feeler lever. The connecting casing pipes are of a ring-shaped structure, and the largest outer diameter of the connecting casing pipes is larger than the outer diameter of the feeler lever.
Description
Technical field
The utility model relates to the pore water pressure force test device in a kind of geotechnical investigation field, the quiet spy equipment of especially a kind of probe.
Background technology
In the geotechnical investigation, often need to arrange the cone penetration test hole of some.Traditional static sounding device comprises probe, feeler lever, also comprises the feeler lever connector sometimes, and the external diameter of the external diameter of feeler lever, feeler lever connector is all identical usually.When using this static sounding device to carry out cone penetration test, be pressed into that feeler lever in the soil layer is omnidistance closely to be contacted with the soil body, produce bigger frictional force between feeler lever 20 and the soil body, and along with the increase of depth of penetration, frictional force is constantly increase also.The feeler lever assembly is pressed into penetration resistance suffered in the soil mainly from acting on resistance on the probe and the frictional force on the feeler lever with probe, when being pressed into, feeler lever assembly and probe reach certain depth in the soil, when penetration resistance increases to the ability that equals the equipment that is pressed into, probe can not continue to be pressed into, and forces test to stop.At present, pore water pressure probe adopts boring to bury underground usually, namely after burying the place underground and adopting the rig pore-forming to reach the requirement degree of depth, the first clean sand of natural part at the bottom of the hole, probe is put into the hole, and back-up sand around probe is used expansive clay (mud ball) to hole then and is all obturaged again.The shortcoming that probe is buried in boring underground mainly contains: 1, construction is complicated, and expense is higher 2, behind the rig pore-forming, and soil body pre-existent pore water pressure changes, and back-up sand around the probe simultaneously can not reach the density of original soil, influences the accuracy in measurement of pore water pressure.
Therefore, plastic hard partially～mould firmly in the shape cohesive soil, when using this traditional static sounding device to carry out cone penetration test, owing to there is very big frictional force between the soil body and the feeler lever, depth of penetration is often more shallow, can not satisfy the design requirement of hole on the degree of depth, so that in the engineering practice, in similar soil layer, have to adopt the probing method to carry out engineering investigation, and the time-consuming effort of probing method, cause prospecting job costs height, and the engineering time is long.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, an easy to operate quiet spy equipment in order to overcome above-mentioned defective exactly.Solve the precision problem of measuring native mesopore water pressure with the better ground that solves, and solved the hole and press probe to be subjected to construction infection easily to cause damages, construct than complicated problems when burying underground, realized the recycling problem to feeler lever simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: the quiet spy equipment of a kind of probe, comprise hole pressure probe, be pressed into feeler lever, described feeler lever is provided with a connection feeler lever at least, feeler lever is arranged with several splicing sleeves at its length direction, the outer external diameter maximum without leave of splicing sleeve is contracted to identical with described feeler lever external diameter to the direction of probe gradually, wherein said connection feeler lever inserts in the described splicing sleeve and with described feeler lever outer wall and contacts, splicing sleeve is cirque structure, and its maximum outside diameter is greater than the external diameter of described feeler lever.
As the further improvement of technical scheme, the outer maximum of external diameter without leave of the described Counterboring apparatus direction of described probe dorsad is contracted to identical with described feeler lever external diameter gradually.When the feeler lever assembly is extracted from soil with probe, the formed lozenges of the diminishing structure of this external diameter of Counterboring apparatus carries out horizontal extruding to the test hole wall, avoid shearing fully longitudinally, also can avoid earth behind Counterboring apparatus, to gather simultaneously, thereby realize that feeler lever assembly and probe reduce the frictional force between Counterboring apparatus and the soil body when extracting from test hole, make feeler lever assembly and probe easily from the soil body, extract.
In the technique scheme, the two ends of every feeler lever are respectively equipped with box thread and male thread, and male thread matches to be spirally connected with box thread on the adjacent feeler lever and realizes being connected of two feeler levers.
In the technique scheme, the maximum outside diameter of described splicing sleeve is 1.1 to 1.15 times of described feeler lever external diameter.
In the technique scheme, the quantity of described connection feeler lever is at least more than two or two, and splicing sleeve and described feeler lever are structure as a whole.
The utility model has the advantages that: adopt segmentation structure to press probe to imbed desired depth in the hole, unnecessary feeler lever can reclaim smoothly; Adopt the injection of earth anchor method hydraulic pressure, if the depth of burying is less and the ground soil property is softer, also can adopt hand quiet spy injection, easy construction; The non-destructive assay environment can make the certainty of measurement of pore water pressure be significantly increased.Make the size of in the soil body test hole that forms greater than the size of feeler lever owing to have splicing sleeve, avoided test hole wall and feeler lever whole process closely to contact, thereby realize that the static sounding device is under the effect of identical penetrating power, obtain darker probe depth of penetration than traditional static sounding device, satisfy test requirements document, reduce testing expenses.
Description of drawings
Below in conjunction with accompanying drawing, by non-limiting for example preferred embodiment of the present invention being described further, in the accompanying drawings:
Fig. 1 is the front view of the utility model embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The quiet spy equipment of a kind of probe, comprise hole pressure probe 1, be pressed into feeler lever 2, described feeler lever 2 is provided with a connection feeler lever 3 at least, feeler lever is arranged with several splicing sleeves 4 at its length direction, splicing sleeve 4 outer external diameter maximums without leave are contracted to identical with described feeler lever external diameter to the direction of probe gradually, wherein said connection feeler lever inserts in the described splicing sleeve and with described feeler lever outer wall and contacts, and splicing sleeve is cirque structure, and its maximum outside diameter is greater than the external diameter of described feeler lever.
As further preferred, the two ends of every feeler lever are respectively equipped with box thread and male thread, and male thread and box thread on the adjacent feeler lever match and be spirally connected being connected of realization two feeler levers.
