Abstract
The utility model relates to a pore water pressure testing device in the field of the geotechnical engineering investigation, in particular to a press-in feeler lever for probe static cone penetration equipment. The press-in feeler lever for the probe static cone penetration equipment is characterized in that the feeler lever is at least provided with a connecting feeler lever; a top structure of the press-in feeler lever is a connecting sleeve; and the diameter of the connecting sleeve is greater than that of the connecting feeler lever, wherein the connecting feeler lever is inserted into the connecting sleeve and is contacted with the top of the feeler lever. The press-in feeler lever has the advantages that a pore pressure probe is embedded into a position at a preset depth by adopting a sectional structure and the residual feeler lever can be successfully recovered; the pore pressure probe is hydraulically injected by adopting a ground anchoring method and can also be injected by adopting a hand-cranking cone penetration mode if the embedded depth is small and the soil quality of a foundation is soft, and the press-in feeler lever is simple and convenient to construct; the measuring environment is protected from being destroyed, and the measuring accuracy of the pore water pressure can be obviously improved.
Description
Technical field
The utility model relates to the pore water pressure force test device in a kind of geotechnical investigation field, and the quiet spy equipment of especially a kind of probe is pressed into feeler lever.
Background technology
At present, pore water pressure probe adopts boring to bury underground usually, promptly after burying the place underground and adopting the rig pore-forming to reach the requirement degree of depth; Elder generation's clean sand of natural parts 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.
The utility model content
The purpose of the utility model is the weak point according to above-mentioned prior art; Provide the quiet spy equipment of a kind of probe to be pressed into feeler lever; Solve the precision problem of measuring native mesopore water pressure with the better ground that solves; And solved the hole and press probe to receive construction infection to be prone to cause damages, to construct than complicated problems when burying underground, realized recycling problem simultaneously to feeler lever.
The realization of the utility model is accomplished by following technical scheme: the quiet spy equipment of a kind of probe is pressed into feeler lever; Comprise hole pressure probe, be pressed into feeler lever; It is characterized in that: said feeler lever is provided with a connection feeler lever at least; The said top structure that is pressed into feeler lever is a splicing sleeve, and said splicing sleeve diameter is not below or equal to and connects the feeler lever diameter, and wherein said connection feeler lever inserts in the said splicing sleeve and with said feeler lever top and contacts.
The quantity of described connection feeler lever is at least more than two or two, and connects between the feeler lever for being threaded.
Described hole presses probe and ramming stem to be welded to connect.
Saidly be pressed into feeler lever one end and splicing sleeve is welded to connect.
Saidly be pressed into feeler lever one end and splicing sleeve is 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,, also can adopt hand quiet spy injection, easy construction if the depth of burying is less and the ground soil property is softer; The non-destructive assay environment can make the certainty of measurement of pore water pressure be significantly increased.
Description of drawings
Fig. 1 is that the utility model hole presses probe to be pressed into the feeler lever sketch map;
Fig. 2 is that the utility model connects the feeler lever structural representation.
The specific embodiment
Through embodiment the utility model characteristic and other correlated characteristic are done further explain below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1～2, figure acceptance of the bid note is respectively: the hole is pressed probe 1, is pressed into feeler lever 2, splicing sleeve 3, connect feeler lever 4, connect feeler lever 5.
Embodiment: hole as shown in Figure 1 is pressed probe 1 and is pressed into feeler lever 2 lower ends and is welded to connect.The top that is pressed into feeler lever 2 is welded with the splicing sleeve 3 of somewhat larger in diameter in the feeler lever diameter, is pressed into feeler lever 2 and is structure as a whole with splicing sleeve 3.Connecting feeler lever 4 inserts in the splicing sleeves 3 and is pressed into feeler lever 2 tops and contacts and form socket.Connection feeler lever 4 as shown in Figure 2 be connected feeler lever 5 and be threaded.
Present embodiment is in the specific implementation: adopt quiet spy to be pressed into to bury the hole underground and press probe 1, adopt static sounding equipment commonly used in the prospecting construction at present, 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.Press burying underground smoothly of probe 1 for guaranteeing the hole; Be pressed into the splicing sleeve 3 that the feeler lever welded top is about 20～30cm; Splicing sleeve 3 diameters are than connecting feeler lever 4 somewhat larger in diameter (being equivalent to enlarged footing); The hole will connect feeler lever 4 when pressing probe 1 to be pressed into inserts in the steel pipe (not establishing screw thread), is pressed into connection feeler lever 4 and makes the hole press probe 1 further deeply.Repeat to insert the connection feeler lever; After the hole presses probe 1 to be depressed into desired depth, on pull out last root and connect feeler lever because the bottom enlarged footing exists; And first connection feeler lever and above feeler lever only are socket through steel pipe with being pressed into feeler lever; Do not have not have and be threaded, thus be pressed into feeler lever 2, the hole presses probe 1 to be embedded in desired depth together, and residue connects feeler lever because being threaded and can reclaiming smoothly between it.The quantity that wherein connects feeler lever can increase according to the needs of the pre-buried degree of depth or reduce.
