As preferably, the position on described floral tube between the first embolism and the second embolism has engraves the hole; The lower port shutoff of floral tube, floral tube upper end can access measureing equipment by aqueduct, and measureing equipment is toward the floral tube water filling, and water enters by shutoff to hole from engraving orifice flow, thereby obtains survey data accurately.。
As preferably, described the first embolism and the second embolism are that the butyl rubber material is made, and the expansion character of described butyl rubber material, sealing performance and ageing-resistant performance are all fine, are conducive to complete the shutoff work of tested segment boring.
As preferably, the length of described the first embolism and the second embolism is 15-20cm, so just can adapt to different boring.
A kind of method of utilizing ice-bound embolism segmentation shutoff boring comprises the following steps:
(1) the first embolism and the second embolism are placed into designated depth in boring;
(2) after putting the position well, first open water valve, pour freezing liquid in the chilled brine case, pressurizeing by gas cylinder is injected into freezing liquid in the first embolism and the second embolism, until the water valve place has cooling fluid to overflow, closes water valve;
(3) after continuation is pressurized to appointment shutoff air pressure by gas cylinder, stop pressurization;
(4) standing to the first embolism and the freezing icing shutoff of namely completing of the second embolism and the contacted place of drill hole wall.
As preferably, in step (2), described cooling fluid is that the concentration of subzero 19 ° is 30% chilled brine.
Beneficial effect: compared with prior art, the present invention has the following advantages: the present invention is simple in structure, with low cost, easily operation, utilize the method for ice-bound embolism shutoff boring to solve the bad problem of embolism shutoff borehole sealing, embolism after effectively having solved leaks and around the test parameter problem bigger than normal that embolism seepage flow causes, makes measurement result more precise and stable.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
With reference to Fig. 1, a kind of device and method that utilizes ice-bound embolism segmentation shutoff boring, comprise gas cylinder 1, one way valve 2, pressure gauge 3 and plugging device, plugging device comprises chilled brine case 4, insulation penstock 5, insulation water output duct 6, the first embolism 7, the second embolism 8, floral tube 9 and water valve 10; Gas cylinder 1, one way valve 2, pressure gauge 3 and chilled brine case 4 are connected successively; The first embolism 7 be connected embolism 8 and connect by floral tube 9, chilled brine case 4, the first embolism 7 and the second embolism 8 are connected successively by insulation penstock 5, described the second embolism 8, the first embolism 7 and water valve 10 also are connected successively by insulation water output duct 6.
As preferably, the position on floral tube 9 between the first embolism 7 and the second embolism 8 has engraves hole 9-1.
As preferably, the first embolism 7 and the second embolism 8 are made for the butyl rubber material.
As preferably, the length of the first embolism 7 and the second embolism 8 is 15-20cm.
operating principle: adopt technique scheme, the designated depth that at first the first embolism and the second embolism is placed in boring sets the position, after putting the position well, first open water valve, pour freezing liquid in the chilled brine case, this cooling fluid is that the concentration of subzero 19 ° is 30% chilled brine, pressurize by gas cylinder freezing liquid is injected in the first embolism and the second embolism, until the water valve place has cooling fluid to overflow, close water valve, at this moment inner filling of the first embolism and the second embolism expired cooling fluid, after continuation is pressurized to appointment shutoff air pressure by gas cylinder, stop pressurization, at this moment the first embolism and the second embolism have expanded and have heaved and push drill hole wall, after a period of time, the first embolism and the second embolism and the contacted place of drill hole wall freezing freezing under the effect of cooling fluid, namely complete shutoff.
