Abstract
The utility model provides a drill bit is surveyed to soil installs the guide instrument module on the drill bit, permselective membrane is installed to the lateral wall on the drill bit, position that permselective membrane pasted be gas reflux pipeline wall and lie in the drill bit on the sword inner wall of atress not, offer a plurality of apertures on the sword inner wall, inside gas reflux pipeline and the carrier gas supply pipe who is equipped with the intercommunication to outside detecting system of drill bit and drilling rod. Gaseous on the drill bit aperture osmotic membrane imbibition gas reflux intraductal, the gas reflux pipeline is carry over intraductal gas to gaseous phase detecting system out of is detected. The static sounding module is still installed to the drill bit front end, can carry out the geology detection to creeping into the stratum.
Description
One, technical field
This utility model relates to a kind of place monitoring device, especially relates to a kind of can directly monitor the drill bit that stratum can be detected by soil gas simultaneously.
Two, background technology
Soil gas monitoring includes the monitoring of volatile organic gas, oxygen, carbon dioxide etc. in soil. At place investigation, for some doubtful pollution or the place having determined that pollution, soil gas monitoring is to judge whether this place soil contaminated or one of the important means of preliminary judgement soil contamination grade. Need a kind of can adopt directly creep into mode professional soil gas monitoring equipment monitor and analyze the soil gas of designated depth below existing structure or other barrier, analysis result can be drawn in real time, for whether carrying out further site investigation offer theoretical foundation, and provide foundation for field investigation and sampling and the quantitative analysis of sample experiments room.
Three, utility model content
This utility model purpose is, soil gas detection monitoring device under a kind of existing structure or barrier is proposed, the composition in the qualitative or semiquantitative monitoring soil gas of on-line monitoring system can be passed through and whether the clear and definite place of content is contaminated and preliminary its pollution level of judgement, the drill bit simultaneously in drilling process, stratum can being detected.
Technical solutions of the utility model are, a kind of soil detection drill bit, drill bit is provided with guide instrument module 5, and drill bit upper side wall is provided with permoselective membrane 1, the position of permoselective membrane patch is gas backstreaming channel wall and is positioned at the sword inwall not stressed on drill bit, and sword inwall is offered some apertures; The gas backstreaming pipeline 2 to external detection system and carrier gas supply line 3 it is communicated with inside drill bit and drilling rod. Gas aperture permeable membrane on drill bit penetrates in gas backstreaming pipe, and gas in pipe is taken out of to vapor detection system 4 and detected by gas backstreaming pipeline. Chisel edge is also equipped with static sounding module 8, it is possible to carry out geology detecting to creeping into stratum.
Guide instrument module integrated on drill bit is that cable-free type guide instrument is connected with ground reception device by wireless, to determine position and the degree of depth of subterranean drill bit. When drill bit horizontal drilling in soil, as situation about deviating with definitive orbit occurs, can in time the position of drill bit be adjusted, so that it is guaranteed that drill bit arrives the designated depth in soil and position. Guide instrument module can adopt SE guide instrument or the module of thunder enlightening RD385 horizontal directional drilling, has good position display ability.
Can carrying out gas phase on-line checking, the online vapor detection device in on-line system adopts conventional portable GC/MS. Portable gas chromatograph is by mass-spectrometric technique and chromatographic technique miniaturization, on-the-spot can provide volatile matter unknown in soil, water body and surrounding air and half volatile matter, especially the qualification result of toxic and volatile substances, it is possible to provide the result of quantitative and semi-quantitative in real time. Having lightweight, space structure to be compact, easy to shift position and the advantage such as reinstall, this quasi-instrument is all from the gentle body source of charged pool, and is furnished with sample pump, exchanges option, a-c transducer at a distance or closely.
Beneficial effect: in site investigation application, at some doubtful contaminated sites or the investigation determining contaminated place, soil gas is to judge that whether this region is contaminated and judge the important evidence of pollution level, therefore can pass through the whether contaminated and contaminated degree of composition and content substantially speculative arbitration place in on-line checking soil gas. This utility model can direct drilling detecting earth formation, and soil Strata In The Aeration Zone soil gas composition and content below existing structure or other barriers can be monitored online on the spot, and preliminary judgement its pollution level whether contaminated for clear and definite place provides basis for estimation, and provides foundation for field investigation and sampling and the quantitative analysis of sample experiments room.
Four, accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Five, detailed description of the invention
In gas-monitoring probe schematic diagram 1, including being provided with gas backstreaming pipeline 2 and carrier gas supply line 3, gas phase monitoring system 4, guide instrument 5, protection shell 6, drill bit 7, static sounding module 8 inside permoselective membrane 1, drill bit and drilling rod that drill bit upper side wall is installed. Selectively penetrating membrane product is attached to outside drill bit side-wall gas reflux pipe, and gas aperture permeable membrane on drill bit penetrates in gas backstreaming pipe, and gas in pipe is taken out of to vapor detection system 4 and detected by gas backstreaming pipeline. Gas backstreaming channel wall is at the sword inwall of drill bit, and does not stress.
Cable-free type guide instrument module integrated on drill bit is connected with ground reception device by wireless, to determine position and the degree of depth of subterranean drill bit. When drill bit horizontal drilling in soil, as situation about deviating with definitive orbit occurs, can in time the position of drill bit be adjusted, so that it is guaranteed that drill bit arrives the designated depth in soil and position. As adopted thunder enlightening RD385 horizontal directional drilling oriented module.
Portable gas chromatograph adopts conventional portable GC/MS, by mass-spectrometric technique and chromatographic technique miniaturization, on-the-spot can provide volatile matter unknown in soil, water body and surrounding air and half volatile matter, especially the qualification result of toxic and volatile substances, it is possible to provide the result of quantitative and semi-quantitative in real time. Detector kind has flame ionization ditector (FID), electron capture detector (ECD) and photoionization detector (PID) etc.
The carrier gas of carrier gas supply line is generally adopted argon, helium or nitrogen.
Drilling tool front end is provided with drilling rod guide probe, static sounding module and gas-monitoring probe, and on-line system includes guide instrument and online vapor detection system, and drill bit is connected with on-line system; In the static sounding module 8 of chisel edge, in drilling process, carry out geology detecting to creeping into stratum. Gas-monitoring probe includes carrier gas supply line, gas backstreaming pipeline, permoselective membrane and the vapor detection device being connected with on-line system; In drilling process, SOIL GAS is known from experience throughout curve permeable membrane and is entered gas backstreaming pipeline, is delivered to the monitoring of vapor detection device, data is sent in time in on-line system afterwards such that it is able to quickly obtain soil gas monitoring result.
Gas-monitoring probe includes carrier gas supply line, gas backstreaming pipeline, permoselective membrane; In drilling process, drill bit 7 creeps into forward, in drilling process, SOIL GAS is known from experience throughout curve permeable membrane 1 and is entered gas backstreaming pipeline 2, being delivered to vapor detection device monitoring 4 by carrier gas supply system 3, data transmitted in time afterwards, on-line system can quickly obtain soil gas monitoring result.
