Description
Technical field
The utility model relates to rock permeability experimental facility, be specifically related to a kind of permeameter.
Background technology
The perviousness of investigation rock is subject to the impact of high confining pressure, and this point is very important.The transmissibility of rock under certain depth or to produce water-based extremely important to design deep structure (as tunnel etc.).Under certain pressure reduction, the ability that rock allows liquid to pass through claims perviousness, and infiltrative size represents by permeability.To the current in most of rock supposition rocks, be laminar flow, flow velocity and hydraulic gradient are linear, follow Darcy's law.Rock permeability represents with infiltration coefficient, and this coefficient is measured at indoor permeameter, measures in the wild by setting-out and bailing test.There is inconvenience, the inaccurate problem of measurement result measured in traditional rock permeability instrument.
Utility model content
For the deficiency existing in prior art, the utility model object is to be to provide a kind of permeameter, simple in structure, measures accurately, convenient and reliable, practical.
To achieve these goals, the utility model is to realize by the following technical solutions: permeameter, comprise seepage water pressure device, rock triaxial cell, buret and manual pump, seepage water pressure Qi Yu rock triaxial cell is connected, and rock triaxial cell is connected with manual pump with buret respectively.
Described seepage water pressure device comprises hand wheel, profit container, constant volume valve, tensimeter mounting hole, switch, pressure-release valve, pouring orifice, eye bolt, petroleum pipeline, top rear screw and profit container base, seepage water pressure device front side is provided with hand wheel, switch, pressure-release valve, hand wheel top is provided with profit container, tensimeter mounting hole, pouring orifice, profit container bottom is provided with two constant volume valves, profit container side is provided with petroleum pipeline, and profit container top is provided with eye bolt.
Before the utility model test, the core of well cutting is put into rock triaxial cell, manual pump is connected with sebific duct, and sebific duct is connected with pressure chamber by a quick pressure releasing device; Manual pump and tensimeter first provide confining pressure before providing permanent hydraulic pressure for the test block in Dui pressure chamber, and buret just can be measured from the sample infiltration water yield in the past like this.Buret is for collecting the volume of the water of experimentation infiltrate rock, thus the permeability of computing rock.
The utility model is simple in structure, measures accurately, convenient and reliable, practical.

When connecing device mouth and emerging, stop refueling, connector is taken out to lid cycle original place.
4) in seepage water pressure device A, inject oil (each renew oil must accurately be changed 2 liters).
5), toward the container water filling on 3500 tops of seepage water pressure device A, water level should be apart from about top 30～40mm, must not be higher than the oil pipe of internal tank, in order to avoid water enters the fuel tank of instrument from oil pipe.
6) open the vent port screw in vessel top, start instrument, oil will up be carried from oil pipe, float on waterbornely, after all air are all discharged in system, screw vent port screw.
7) B upper end, rock triaxial cell is connected with any outlet valve of seepage water pressure device A, and lower end is connected with measuring guide.
8) start seepage water pressure device A pressurization, until there is a certain amount of water (now not adding confined pressure) on conduit, close flowing water Valve.
9) start manual pump, apply and maintain specific confined pressure, then open seepage water pressure device A flowing water Valve, and start seepage water pressure device A to required force value.10) measuring guide water level rises, timing reading.
This embodiment is simple in structure, measures accurately, convenient and reliable, practical.
