Description
Technical field
The utility model belongs to Hydraulic and Hydro-Power Engineering, prospecting test apparatus, is mainly used in HIGH-PRESSURE INJECTION EXPERIMENT or rock cleavage test.
Background technology
At present, the domestic test method for the test of Hydraulic and Hydro-Power Engineering field and evaluation rock permeability, mostly adopts water pressure test in borehole to obtain permeability of surrounding rock index, according to water pressure test in borehole assessment of result rock permeability.In boring, be lowered to embolism and carry out test section isolation, by pipeline, to test section water filling, carry out packer permeability test, according to computing rock permeability rates such as pressure, flow, test section length, setting-out times.
Conventionally the embolism that test section isolation adopts has mechanical roof pressing type, vapour-pressure type, hydraulic type etc., and feature and the applicable elements of various conventional embolisms are summarized as follows:
1. roof pressing type embolism: this embolism combines one group of cylindrical rubber piece by core pipe is a kind of single embolism structure.Be applicable to isolate test section from foot of hole, can only carry out the packer permeability test of a test section at every turn, boring and packer permeability test must be hocketed.Embolism isolation effect is generally poor, and work efficiency less trouble is high, and test result precision is very low, but owing to being widely used for many years, so far still in a large amount of use.
2. vapour-pressure type embolism: generally formed by inner tube and capsule, have two types of Dan Sai and two plugs.The same with roof pressing type embolism, vapour-pressure type list plug can only carry out the packer permeability test of a test section at every turn, and work efficiency is lower; The two plugs of air pressure can, after boring finishes, carry out packer permeability test from top to bottom or from bottom to top piecemeal, and work efficiency is higher.The subject matter that such embolism exists is that structure and equipment are more complicated, failure rate is high, poor reliability, and pressure is low, usable range is restricted, and quality of achievement is lower.
3. low-pressure hydraulic type embolism: generally formed two types of point Dan Sai and two plugs by inner tube and capsule.The same with roof pressing type embolism, hydraulic type list plug can only carry out the packer permeability test of a test section at every turn, and work efficiency is lower; The two plugs of hydraulic pressure can, after boring finishes, carry out packer permeability test from top to bottom or from bottom to top piecemeal, and work efficiency is higher.The subject matter that such embolism exists is that complex structure, failure rate are high, poor reliability.After capsule water-filling, cause residual deformation cause discharging water not thorough, embolism can not with hole wall depart from completely made plug difficulty even cause capsule breakage; Pressure is low, usable range is restricted, and quality of achievement is lower.
Along with developing by leaps and bounds of prospecting technique and improving constantly of packer permeability test technical requirement, low-pressure water-pressurizing test method and utensil are also constantly being eliminated and are upgrading.
Summary of the invention
The problems such as the utility model provides a kind of hydraulic type high pressure two embolism packer permeability test devices, and the ubiquitous test pressure of current water pressure test in borehole common method is little, embolism structure is complicated, failure rate is high to solve, poor reliability, inefficiency, quality of achievement are poor.
The technical scheme that the utility model is taked is: flow guiding connector is threaded with pressure pipe, this pressure pipe is threaded with the top connection of top plug, the lower linking tube of this top plug is threaded with floral tube, the bottom of this floral tube is threaded with the top connection of lower plug, bottom has the water injection pipe of plug to be positioned at pressure pipe, top plug, lower plug inside, and there is O RunddichtringO this water injection pipe and top plug, lower plug contact site;
The structure of described top plug is: top connection one is threaded with middle adapter one, and water threeway one upper end is threaded with middle adapter one, lower end is threaded with lower linking tube one, and capsule one upper end is threaded with top connection one, lower end and lower linking tube one are slidably connected;
The structure of described lower plug is: lower sub two is threaded with middle adapter two, and water threeway two upper ends are threaded with middle adapter two, lower end is threaded with lower linking tube two, and capsule two upper ends are threaded with top connection two, lower end and lower linking tube two are slidably connected.
?the utility model has the advantages that novel structure, reliable, simple operation.The sealing of outer plug, inner tube water filling are divided into two cover autonomous systems, between only in water threeway place, the sealing of O type circle is set, structure extremely simplify and sealing reliability high, processing and manufacturing with install and use simple and efficient.Fill pressure directly monitoring, the operation of filling, discharge water is very simple and reliable.Water injection pipe is promoted to certain altitude can be by observing the tensimeter indication numerical value intuitive judgment embolism situation that discharges water.Fabulous distortion recovery and low pressure are filled performance, go for water pressure test in borehole and the rock cleavage test of various pressure completely.Embolism capsule adopts top-quality rubber and metal mesh shaped braiding structure, and capsule is highly sensitive, and deformation behavior is extremely strong, has low compressive strain and recovers feature.
