Detailed description of the invention
For understanding the utility model better, below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, monitor well air bag water barrier, comprise water proof air bag 3, water proof air bag 3 is cylinder barrel shaped structure, install in the borehole wall of monitor well 1 and the gap of tube connector 2, the top tracheae of water proof air bag is connected with the vertical channel of the bottom of linkage 4, the tube wall of tube connector 2 has pore, the bottom of air inlet pipe 5 is passed in the horizontal channel of the inner side of pore and linkage, vertical channel is connected with horizontal channel and forms " L " type passage 6, the top of air inlet pipe 5 is connected with air pump, tube connector 2 is the cylindrical tube structure of outer middle side part indent, the inner groovy place of tube connector is all located at by water proof air bag 3 and linkage 4.
As in Figure 2-4, linkage 4 is provided with the circumferential band body structure of opening for side, the bilateral symmetry of opening is provided with two pieces of junction plates 7, the opposite side of linkage is provided with rectangular blocks 8, the inside of rectangular blocks 8 is provided with " L " type passage 6, and linkage 4 is coated at tube connector 5, and junction plate 7 is connected by bolt and makes linkage lock ring on tube connector, be provided with hydro-expansive rubber band 9 between linkage and tube connector, hydro-expansive rubber band 9 has through hole with pore corresponding position.
When using the utility model to carry out sampling detection, first the monitor well 1 of predetermined hole diameter is drilled through by rig, the distribution situation of underground reservoir 10 and non-aqueous layer 11 is obtained by turning hole, during installation, first hydro-expansive rubber band 9 is matched with tube connector 2, the through hole on hydro-expansive rubber band and the perforate of tube connector is made to be that axiality coordinates, then water proof air bag 3 is matched with tube connector, its top tracheae is coordinated with the fine thread hole, bottom of the rectangular blocks 8 of linkage 4, ensure that tightness reaches requirement with sealing ring during cooperation, simultaneously, air inlet pipe 5 bottom is coordinated with the fine thread hole, inner side of linkage 4, ensure that tightness reaches requirement with sealing ring when in like manner coordinating, now then linkage 4 and tube connector 2 can be fixed, use stainless steel bolt lock ring, ensure tube connector, hydro-expansive rubber band, linkage is pressed shown in Fig. 2 and is coordinated, so just can ensure that the water sample in aquifer can not enter monitor well inside, serve good sealing function, next the monitor well tube connector assembled, hydro-expansive rubber band, linkage, air inlet pipe, water proof air bag are inserted in the monitor well having drilled through out, the gas in water proof air bag extracted out by air pump first by air inlet pipe and earth's surface when inserting, water proof air bag is tightened, periphery is close to inwall, prevent from being scratched inserting to contact with the borehole wall after water ballonet, and water proof balloon positions offsets, do not reach the water proof effect of expectation, after being placed to preposition, by air inlet pipe, water proof air bag is inflated, with reference to the air gauge that earth's surface is connected with air inlet pipe during inflation, make it to reach surface simulation degree of depth atmospheric pressure value and can complete installation.
Expansion to a certain degree can be there is in the hydro-expansive rubber band 9 between tube connector 2 and linkage 4 after the immersion through underground water, thus the gap between tube connector and linkage is disappeared, thus effectively prevent the water of outside from entering monitor well inside, cause boss structure to not give whole monitor well and installation work difficulty is increased, this linkage marginal position must be consistent with tube connector bassoon external diameter, and the bolt that this linkage uses is necessary for stainless steel material, the utility model utilizes high performance water proof air bag 3 underground reservoir 10 and non-aqueous layer 11 to be kept apart, ensure monitor the reset condition of water layer.
