Abstract
The utility model discloses a plug water separator with multiple conical indenter sections. The plug water separator is characterized in that a plurality of conical indenters and a plurality of rubber plugs are sequentially serially connected with each other on a connecting rod to form the water separator, the conical indenters are cones with axial through holes, and the conical indenters and the rubber plugs are in pairs and are disposed on the connecting rod in a serial connection manner. Compared with the prior art, the plug water separator is simple in structure, convenient in use and fine in reliability, is applicable to water stop of various stratums, and greatly improves accuracy and reliability of packer permeability tests.
Description
Technical field
The utility model relates to the geological mapping technical field, specifically a kind of multistage awl pressure type embolism water stop that is used for packer permeability test.
Background technology
In the geological mapping of projects such as water conservancy, water power, bridge, tunnel and nuclear power and boats and ships water conservancy project, often need to adopt packer permeability test to obtain basement rock or concrete transmission coefficient, the key of packer permeability test is the water-stop that the section of examination is isolated, and the success or failure that the examination section is isolated are directly restricting the accuracy and reliability of test result.
The water-stop of prior art, the water-stopping structure of employing sheathed Jiao Dun on connecting rod, realize the isolation sealing of packer permeability test, slidably connecting rod is through on Jiao Dun and the pressure pad, utilize the hydraulic pressure of rig that bottom integral body is exerted pressure from the aperture, Jiao Dun bears hydraulic pressure down, make Jiao Dun by the cylindric deformation that becomes colyliform, in the process of Jiao Dun distortion, contact surface and the hole wall of Jiao Dun are close to, realize the sealing of packer permeability test, in the process of Jiao Dun distortion, owing to the contact surface of Jiao Dun and hole wall can't be close to tight or be close to the too small effect that influences sealing of face, even, inhomogeneous or the folk prescription of glue pier spreading causes the not obvious or sealing failure of stagnant water effect to spreading.
The utility model content
The purpose of this utility model is a kind of multistage awl pressure type embolism water stop that designs at the deficiencies in the prior art, the water-stopping structure that adopts awl depressor and rubber embolism multistage to be provided with, in packer permeability test, make the contact surface of rubber embolism and hole wall bigger, more tight, realize the tight sealing of packer permeability test, improve stagnant water effect.
The concrete technical scheme that realizes the utility model purpose is: a kind of multistage awl pressure type embolism water stop, be characterized in that this water stop is by serial connection awl depressor and rubber embolism are formed successively on the connecting rod, connecting rod is shaft-like adapter, the awl depressor is the cone that is axially arranged with through hole, the rubber embolism is the sleeve pipe of short cylinder, the awl depressor is that paired and a plurality of the serial connection is arranged on the connecting rod with the rubber embolism, and awl depressor and rubber embolism and connecting rod are for being slidingly connected.
The utility model compared with prior art has simple in structure, and is easy to use, and good reliability is applicable to the sealing of multiple rock stratum, has improved the accuracy and reliability of packer permeability test greatly.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is awl depressor structural representation;
Fig. 3 implements illustration for the utility model.
The specific embodiment
Consult accompanying drawing 1 ~ accompanying drawing 2, the utility model is formed by being connected in series several awl depressors 2 and rubber embolism 3 on the connecting rod 1 successively, connecting rod 1 is shaft-like adapter, awl depressor 2 is for being axially arranged with the cone of through hole 21, rubber embolism 3 is the sleeve pipe of short cylinder, awl depressor 2 and rubber embolism 3 in pairs and several be connected in series and be arranged on the connecting rod 1, awl depressor 2 and rubber embolism 3 and connecting rod 1 are for being slidingly connected.
More than just the utility model being further described, is not in order to the restriction this patent, and all is that the utility model equivalence is implemented, and all should be contained within the claim scope of this patent.
