Description
Technical field
The invention belongs to hydrogeology field, particularly to a kind of vapour-pressure type rock body drilled depthkeeping water fetching device, be a kind of for below rock body drilled phreatic line, the water fetching device of depthkeeping water intaking.
Background technology
Rock body drilled refers to the boring implementing to creep in bedrock formation region.Under normal circumstances, for measuring or verifying the quality of groundwater situation in rock body drilled section, then need to fetching water in designated depth, institute's water sampling must be in targeted test section, to ensure the accuracy measuring structure.But, if targeted test section is positioned at below boring phreatic line, how to realize fetching water in designated depth, still there is no simple and reliable apparatus, accordingly, it would be desirable to study further.
Summary of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of vapour-pressure type rock body drilled depthkeeping water fetching device, in rock mass bores below phreatic line, it is achieved that depthkeeping is quantitatively fetched water, and has a good application prospect, and is worthy to be popularized.
For solve the problems referred to above, the present invention specifically by the following technical solutions:
A kind of vapour-pressure type rock body drilled depthkeeping water fetching device, it is characterized in that, including intake pipe and the pressurized seal system being arranged on intake pipe top, described pressurized seal system includes air-pressure chamber and air bag, described air-pressure chamber is the circular of inner hollow, and the internal ring side of described air-pressure chamber is provided with air bag, and described air-pressure chamber is provided with and controls the baroswitch that air pressure indoor gas injects and discharges, the upper end of described intake pipe is provided with scupper, and described scupper is arranged on the top of pressurized seal system.
Aforesaid a kind of vapour-pressure type rock body drilled depthkeeping water fetching device, it is characterised in that the height of described air-pressure chamber is 10cm.
Aforesaid a kind of vapour-pressure type rock body drilled depthkeeping water fetching device, it is characterised in that described baroswitch is provided with the rubber seal plug preventing gas leakage.
Aforesaid a kind of vapour-pressure type rock body drilled depthkeeping water fetching device, it is characterised in that described intake pipe is made up of steel pipe.
Aforesaid a kind of vapour-pressure type rock body drilled depthkeeping water fetching device, it is characterised in that this water fetching device is connected with cable winch, described suburb line car is provided with the depth controller controlling this water fetching device placement degree of depth.
Beneficial effects of the present invention: a kind of vapour-pressure type rock body drilled depthkeeping water fetching device provided by the invention, including intake pipe, pressurized seal system and scupper, pressurized seal system is arranged on the top of intake pipe, and scupper is arranged on the top of pressurized seal system, so, before water fetching device arrives below the phreatic line specified position, baroswitch first with pressurized seal system injects air in air-pressure chamber, so that the air bag of air-pressure chamber internal ring side is closed, then cannot be introduced in intake pipe from the subsoil water of the non-designated position that scupper enters；And when water fetching device arrives and specifies position, then utilizing baroswitch to discharge the air in air-pressure chamber, airbag-releasing, then the subsoil water now leaking into specified location from scupper is sampled, it is ensured that the depthkeeping of sampling is quantitative.This vapour-pressure type rock body drilled depthkeeping water fetching device, mainly solves the rock body drilled depthkeeping On Computation for Drawing Water below level of ground water, has that cost is low, a simple in construction and realize the advantage that depthkeeping is quantitatively fetched water.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of vapour-pressure type rock body drilled depthkeeping water fetching device of the present invention.
Accompanying drawing labelling implication is as follows:
1: intake pipe；2: air-pressure chamber；3: air bag；4: baroswitch；5: scupper.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, a kind of vapour-pressure type rock body drilled depthkeeping water fetching device, including intake pipe 1 and the pressurized seal system being arranged on intake pipe 1 top, described pressurized seal system includes air-pressure chamber 2 and air bag 3, described air-pressure chamber 2 is the circular of inner hollow, the internal ring side of described air-pressure chamber 2 is provided with air bag 3, described air-pressure chamber 2 is provided with and controls the baroswitch 4 that in air-pressure chamber 2, gas injects and discharges, the upper end of described intake pipe 1 is provided with scupper 5, described scupper 5 is arranged on the top of pressurized seal system, determine whether the subsoil water leak into from scupper 5 enters in intake pipe by the control of pressurized seal system, so that it is guaranteed that the accuracy of sampling, and due to the constancy of volume of intake pipe 1, therefore, effective quantitative sampling is ensure that while spot sampling.
Further, the height of described air-pressure chamber 2 is 10cm, and described baroswitch 4 is provided with the rubber seal plug preventing gas leakage, effectively places gas leakage, and described intake pipe 1 is made up of steel pipe, and price is suitable, and the time of use is permanent.
In addition, this water fetching device is connected with cable winch, control to put in pre-drilled boring by this water fetching device by suburb line car, described suburb line car is provided with the depth controller controlling this water fetching device placement degree of depth, water fetching device position location in the borehole is controlled, in order in targeted test section, obtain required water sample by depth controller.
If use this water fetching device near below phreatic line, first ensure in intake pipe anhydrous, then pass through baroswitch, inflate in air-pressure chamber, until the air bag in the middle of air-pressure chamber is closed；If water intaking the degree of depth deeper below phreatic line, abundant gas need to be injected in air-pressure chamber, with ensure air bag under high water head pressure effect water-tight.Air pressure room air enough after, close baroswitch, by cable winch to placing this water fetching device in rock body drilled to designated depth.When designated depth is fetched water, by the controller remote control baroswitch on cable winch, baroswitch is opened, bleeds off the gas in air-pressure chamber, then in the water inlet of the water in rock body drilled intake pipe, thus completing the following depthkeeping water intaking of phreatic line in rock body drilled.
