Thus; the present invention can bury observation instrument segmentation separately underground; observation instrument (osmometer etc.) cable outsourcing protective casing; joint area at protective casing adopts raw material band antiseepage; cannula tip is established silently; casing wall bores quincunx hole and transmits water pressure; sleeve outer wall bag filter screen is to stop silt to enter pressure test section; adopt precision pressure gauge to be connected on the position, earth's surface of cable protecting sleeve outward; coordinate high-pressure stop valve can be easily to boosting and the osmotic pressure of buck stage is effectively observed, observation instrument shutoff adopts the plugging technology of geotextiles in conjunction with back-grouting.
Be below the technical scheme of further improvement of the present invention:
Further, between described geotextiles section and test cavity, be provided with elastic baffle.
In order to facilitate the water and air in drain sleeve, drainage exhaust switch is equipped with on described sleeve pipe top.
As a kind of concrete form of structure, the plug of described sleeve bottom be shutoff silently.
As a kind of concrete form of structure, the plug at described sleeve pipe top is epoxy resin plug.
For the pressure in Real-Time Monitoring sleeve pipe, water pressure table is equipped with on described sleeve pipe top.
For the ease of discharging in time the gas in expansion cement slurry block section, described expansion cement slurry is provided with the stack being in communication with the outside in block section.
For convenient slip casting in geotextiles section, described test observation is provided with a Grouting Pipe in hole, and the bottom of this Grouting Pipe is placed in described geotextiles section.
Operating principle of the present invention is: be the survey data of Obtaining Accurate HIGH-PRESSURE INJECTION EXPERIMENT, need to improve observation instrument burial and construction quality and non-observation section is carried out to effective shutoff, the present invention buries observation instrument segmentation separately underground, at observation instrument (osmometer etc.) cable outsourcing protective casing, joint area at protective casing adopts raw material band antiseepage, establish silently outsourcing protective casing end, casing wall bores quincunx hole and transmits water pressure, sleeve outer wall bag filter screen is to stop silt to enter pressure test section, adopt precision pressure gauge to be connected on the position, earth's surface of cable protecting sleeve outward, coordinate high-pressure stop valve effectively to observe the osmotic pressure of experimental stage easily, observation instrument shutoff adopts the plugging technology of geotextiles in conjunction with back-grouting.
Compared with prior art, the invention has the beneficial effects as follows: the present invention can be easily and fast, effectively observation instrument is installed to design attitude; Avoid burying the destruction of process to observation instrument cable underground in installation; Stop silt to enter pressure test section; Increase the safety factor of test observation means, the osmotic pressure of each experimental stage has effectively been observed; Overcome cement (sand) slurry or dry sea-tangle plugging technology deficiency, effectively guaranteed plugging effect, prevented that peephole hole wall and cable top layer from forming penetrating passage and the grout leaking that causes, leak.
Below in conjunction with drawings and Examples, the present invention is further elaborated.
