Abstract
The utility model relates to a portable hydraulic tester for pneumatic drill holes, which is composed of seal pipes, a connection pipe, a rubber pipe, a capsule, a water inlet pipe, a hydraulic pipe, a joint pump pipe, a fluid meter, etc. The double-pipe double-valve hydraulic pipe and two identical seal pipes are adopted to form two seal cavities, and a connection pipe forms a hydraulic cavity. The hydraulic cavity is provided with the rubber pipe and a plurality of water outlet holes which cause the water to flow into the hydraulic segments of the drill holes. The seal cavity is surrounded by the capsule, and the upper side of the seal cavity is provided with a plurality of water outlet holes which cause the water to press the capsule under the action of the water pressure to seal the drill holes. The distances of the hydraulic segments can be changed, and the water consumption can be directly read by a flowmeter. Moreover, the water permeability of the rock mass is known via the unit water consumption to reveal the internal structure of the rock mass.
Description
The utility model is the light packer permeability test device in a kind of air drill hole, is called for short water pressurizing device below, belongs to the rock mass test, and advance geologic gives the test apparatus of newspaper.
Existing advance geologic gives the packer permeability test instrument of newspaper, needs to be equipped with special boring apparatus, can only carry out in the vertical exploratory hole in the face of land, what test only is the characteristic variations of vertical direction rock mass, be unable to do without rig and equipment heaviness during test, complicated operation takies the long engineering time.
At the problem of above-mentioned existence, the utility model proposes a kind of construction speed that promptly do not influence, can improve advance geologic prediction speed again, the light and light hole of wind easy operating light packer permeability test device.
The purpose of the utility model water pressurizing device is to realize like this, owing to exist the crack that varies in size in the rock mass, therefore have multiple geological phenomenon, when packer permeability test is carried out in rock mass air drill hole, the rock mass that complete mechanical strength is lower, specific water absorption is little, and by the crack of clay filling, water absorbing capacity is also little, but it is higher at hydraulic pressure, keep under the situation of certain hour, the clay of filling is softened and washes away, and water absorbing capacity increases; Width is little is used to wearing property crack, and its water absorbing capacity is big, the solution cavity of sealing, and its water absorbing capacity is also little.So, by measuring the rock mass specific water absorption, can understand the rock mass water permeability, disclose the rock mass internal structure.Air drill hole packer permeability test is divided the weathering unloaded band in definite rock mass internal structure, is better than other existing means of testing.
The utility model water pressurizing device adopts two-tube double valve setting-out, makes sealing boring original paper with capsule, and distance is the distance variable (changing the length of sebific duct and connecting pipe) of compressed water section between two sealed tubes, directly reads water consumption with flowmeter.
Describe structure of the present utility model in detail below in conjunction with drawings and Examples, install and the course of work.
Fig. 1 is the structural representation of the light water pressurizing device in the utility model air drill hole.
Fig. 2 is light water pressurizing device in the utility model air drill hole and water pump connection diagram.
Please refer to Fig. 1, the utility model water pressurizing device is made up of plug (1), sealed tube (2), connecting pipe (3), sebific duct (4), capsule (5), water inlet pipe (6), valve (7), connecting pump tube (8), valve (9), pressure pipe (10), flowmeter (11).Wherein, water inlet pipe (6) one ends pass in a plug one sealed tube, from a plug, pass again with sebific duct (4) one ends and be connected, the other end passes a plug, sebific duct (4) other end links to each other, and forms inlet pipeline, and capsule (5) is sealing boring original paper, its two ends are pressed on the sealed tube with the urheen line, and shape is at annular seal space.Pressure pipe (10) one ends link to each other with flowmeter (11), and the other end passes a plug and a sealed tube enters in the connecting pipe (3), form the setting-out pipeline, and wherein connecting pipe is a setting-out chamber, comprises sebific duct (40) in the chamber and several apopores are arranged.Sealed tube (2) is a sealing setting-out chamber, and several apopores are arranged on the chamber, and by capsule (4) institute around.
Water pressurizing device recited above has two identical sealed tubes (2) and a connecting pipe (3), and two identical sealing setting-out chambeies and a setting-out chamber are also promptly arranged.
Water pressurizing device is installed, and at first with together corresponding sealed tube plug (1) weldering of sealed tube (2) knot, again with water inlet pipe (6), pressure pipe (10) is tied with the sealed tube plug weldering that is connected separately respectively.With the urheen line capsule (5) two ends and sealed tube (2) two ends are bound, in like manner with sebific duct (4) two ends and water inlet pipe (6) two ends and the encircling of water inlet pipe (6) two ends.With screw connecting pipe (3) and two sealed tubes are screwed, several apopores are arranged in the connecting pipe, water is entered in the fields water injection section, several apopores are also arranged in the sealed tube, make water enter capsule, play sealing boring.
The operating process of the utility model water pressurizing device please refer to Fig. 1, Fig. 2.
At first connecting pump tube (8) and wobble pump (13) are connected, open valve (7), valve-off (9), (14), then water pressurizing device is put into the air drill hole, with manual manipulation manual pump (13), water extrudes in the pump after valve (7) enters water inlet pipe (6), and water flows into the sealed tube from water inlet pipe respectively, capsule under hydraulic action (5) thus expand and be adjacent to hole wall and make and form seal section between two capsules.This moment is when observing the indicated pressure of tensimeter (12) and reaching desired value, read initial value from flowmeter (11), after the pressure stability, read the flow evaluation once more, open valve (14), (7) then, water is discharged, so just finished the setting-out overall process of a boring.
The advantage of the utility model water pressurizing device:
1, device structure is simple, and is with low cost;
2, has traditional packer permeability test equipment advantage;
3, easy to operate, do not need special punch device;
4, the experiment personnel selection is few, does not take the engineering time;
5, be not afraid of construction and disturb, (20~40cm) is variable for the experimental test section.
