Description
Technical field
The utility model relates to geotechnical engineering Pore Pressure measurement mechanism.
Background technology
In geotechnical engineering, in all kinds of grounds and foundation construction process, conventionally need to observe the variation of the pore water pressure in soil layer, the method for embedding of pore pressure gauge generally adopts boring to bury method underground at present, and is generally that a pore pressure gauge is buried in a hole underground.Method is buried in traditional boring underground, and it is larger that a labor intensive physical resources and financial resources is buried in a hole underground, buries the cycle underground long, but effect is generally better; The defects such as the technology of many is not also very ripe, and often inaccuracy is located in appearance, and upper and lower packing is bad are buried in one hole underground.
Summary of the invention
The utility model provides a kind of serial-type pore water pressure measuring device.
The technical solution of the utility model adopts pore pressure gauge, permeable stone, connecting rod, it is characterized in that pore pressure gauge, permeable stone is the inner chamber at a body with sealing ring fixing seal, there is internal thread at the two ends of body, and is furnished with respectively Connection Block, Connection Block has the port assemblies of external screw thread and body, there is internal thread at the center, outer face of Connection Block, there is external screw thread at the two ends of connecting rod is furnished with locking nut, for the Screw assembly with center, Connection Block outer face, the upper end Connection Block that is contained in body upper port has cable through-hole, earth's surface is derived and extended to the cable of pore pressure gauge from the Connection Block cable through-hole of body upper end, in the middle and lower part of body cavity, offer a plurality of permeable holes, current enter body cavity inside by permeable hole, in permeable stone, form hydraulic pressure, by the water-pressure survey pore water pressure value in permeable stone, by connecting rod, above-mentioned pore water pressure measurement device is coupled together one by one, become a kind of serial-type pore water pressure measuring device.
The utility model, owing to pore pressure gauge being installed in a body, by connecting rod, can be realized a hole and bury many pore pressure gauges underground, and registration, and upper and lower packing is good.Both can solve conventional borehole buries in method a hole underground and buries higher, the consuming time problem such as long of expense producing underground; The problems such as many location inaccuracy that produce, upper and lower packing are bad are buried in the hole of can solving over again underground.
