Description
Technical field
The utility model relates to geology equipment research and development field more particularly to a kind of layering watertight rubber cylinders.
Background technique
Currently, China just carries out high-precision survey for the purpose of locating hydrogeological resources in China, a large amount of hydrogeology point is implemented
Layer exploratory hole and underground water multilayer monitoring well, for accurately portraying aquifer structure, accurate evaluation groundwater resources.
Implement layering exploratory hole and underground water multilayer monitoring well at present, manages outer sealing and use POLARGEL NF ball more, due to
Machining accuracy is different, when to be enclosed that the annular space gap filled out is smaller, sealing position is deeper, it is more difficult to realize smart between layers
True sealing.In addition, China technical staff has developed separate zone stimulation system in relevant pipe to realize layering long-term observation, but
When implementing packing in 3 layers and the above well, since middle layer position needs two or more sets well casings of tripping in simultaneously, generally using kelp or
Hydro-expansive rubber band carries out Inter-zonal packing, but both materials, due to not high with well casing laminating degree, water-stagnating effect is poor, and
It constructs cumbersome, takes considerable time and cost, have a single function, it is not very practical.
Summary of the invention
The purpose of this utility model is solved in above-mentioned background technique, and packing uses kelp or water-swellable in existing well
When rubber strip carries out Inter-zonal packing, both modes and well casing laminating degree be not high, and water-stagnating effect is poor, and it is cumbersome to construct, consumption
Take plenty of time and cost, have a single function, it is not very practical the problems such as, and provide a kind of layering watertight rubber cylinder.
A kind of layering watertight rubber cylinder, is made of the first metal tray, the second metal tray and multichannel rubber tube, the
One metal tray and the second metal tray pass through several bolts respectively and are fixed at multichannel rubber tube upper/lower terminal, multi-pass
There are several well casing pipelines, the first metal tray is identical with the second metal tray structure, the first metal tray inside road rubber tube
It is upper that there are several hollow boss, in the several hollow boss and multichannel rubber tube in the first metal tray and the second metal tray
Several well casing pipelines in portion match connection respectively；
First metal tray is two-flap type, is made of two semi-circular structures；
The multichannel rubber tube is the solid rubber cylinder of cylindrical shape.
The use process of the utility model:
In use, selecting corresponding first metal tray, the second metal tray and multichannel rubber according to well casing quantity
Cylinder, now respectively penetrates several well casings in several well casing pipelines of multichannel rubber tube, well casing upper and lower ends use the first gold medal respectively
Belong to pallet and the second metal tray to fix, the utility model suspends G.I.H predetermined position in midair with well casing, realize layer and layer it
Between sealing, multichannel rubber tube sufficiently contacts and expanded with water, realizes interlayer expansion packing, both guarantees to be layered sealing utensil
Smooth tripping in, and guarantee that multichannel rubber tube can sufficiently realize that interlayer is effectively isolated after realizing itself swelliong power.
The utility model has the beneficial effects that
The utility model simple installation, sealing performance are reliable, can customize size according to the actual situation, can be underground water multilayer
Monitoring well monitoring can change layering sealing in single tube column multilayer monitoring well, nested monitoring well, continuous multi-channel testing well and pipe
The system of making, which be effectively layered inside and outside pipe, provides materials for support, and it is horizontal to improve China's underground water layering exploration technique.

Specific embodiment
Refering to fig. 1, shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of layering watertight rubber cylinder is by the first metal tray 1, second
Metal tray 2 and multichannel rubber tube 3 form, and the first metal tray 1 and the second metal tray 2 are solid by several bolts 1 respectively
Fixed be arranged inside 3 upper/lower terminal of multichannel rubber tube, multichannel rubber tube 3 has several well casing pipelines 21, the first metal support
Disk 1 is identical with 2 structure of the second metal tray, has several hollow boss 11,1 He of the first metal tray in the first metal tray 1
Several hollow boss 11 in second metal tray 2 match respectively with several well casing pipelines 21 inside multichannel rubber tube 3
Connection；
First metal tray 1 is two-flap type, is made of two semi-circular structures；
The multichannel rubber tube 3 is the solid rubber cylinder of cylindrical shape.
The use process of the utility model:
Refering to fig. 1, shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, in use, selecting corresponding first metal according to 4 quantity of well casing
Several well casings 4, are now respectively penetrated several wells of multichannel rubber tube 3 by pallet 1, the second metal tray 2 and multichannel rubber tube 3
In pipeline 21,4 upper and lower ends of well casing use the first metal tray 1 and the second metal tray 2 fixed respectively, the utility model with
Well casing 4 suspends G.I.H predetermined position in midair, realizes sealing between layers, and multichannel rubber tube 3 is sufficiently contacted with water and swollen
It is swollen, it realizes that interlayer expands packing, not only guarantees the smooth tripping in for being layered sealing utensil, but also guarantee that multichannel rubber tube 3 is being realized certainly
It can sufficiently realize that interlayer is effectively isolated after body swelliong power.
