Abstract
The utility model relates to an air bag type drilling water-sealing up packer which is composed of an upper blockage joint, a lower blockage joint, an air bag, a water filling pipe and an air filling pipe. The air bag is in pipe-shaped, and a water filling pipe hole and an air filling pipe hole are arranged on the upper blockage joint and the lower blockage joint. The water filling pipe passes through the water filling pipe hole, and the air filling pipe is connected with the upper part of the air filling pipe hole. The utility model can pack drilling holes with various hole diameters. The utility model has the advantages of high pressure resistance, large expansion coefficient, good packing effect and simple and fast operation, and is especially suitable for packing a complicated geologic structure and the drilling hole with an irregular hole wall. A plurality of groups of packers are used, and the packer is used for the anti-seepage and pressure grouting construction project of the dam foundation of a water reservoir.
Description
The utility model relates to a kind of gasbag-type boring sealing packer.
Water pressure test in borehole is an important tests project in the geological mapping work, when testing, need test section is stopped up sealing, used glueballs embolism sealing sealing, its packing is apart from weak point in the past, and the coefficient of expansion is little, stagnant water effect is poor, efficient is low, and labour intensity is big, when especially complicated and hole wall is irregular at earth formation, just can not effectively seal, thereby be difficult to satisfy the requirement of geology and design department workmanship.
The purpose of this utility model provides a kind of boring packing that can carry out longer distance, withstand voltage height, and the coefficient of expansion is big, and packing is effective, and is convenient to operation, can be applicable to the gasbag-type boring sealing packer of bad ground and irregular boring.
The utility model is by packed joint, air bag, water injection pipe, air injection pipe constitute up and down, described air bag is a tubulose, the both ends of pipe are placed in up and down on the packed joint, be equipped with water filling pore and gas injection pore up and down on the packed joint, water injection pipe runs through and mistake from the water filling pore of two joints, and air injection pipe then is connected on the gas injection pore.
Preferably be provided with an airflow cyclotron cavity in the above-mentioned packed joint.
The utility model can carry out the packing of multiple aperture boring, withstand voltage height, the coefficient of expansion is big, packing is effective, easy and simple to handle, quick, especially can be applicable to the packing of the complicated and irregular hole wall boring of geologic structure, and can many assembly close to use and carry out multistage and separate sealing, also can be used for reservoir seepage prevention of dam founda pressure grouting construction works simultaneously.
Below in conjunction with accompanying drawing the utility model is described.
Accompanying drawing is the structural representation of Cui example of the utility model.
With reference to accompanying drawing, the utility model is by packed joint (3), air bag (4), water injection pipe (5) tracheae (1) are formed up and down, air bag is a tubulose, the both ends of pipe are placed in up and down on the packed joint, be equipped with water filling pore and gas injection pore up and down on the packed joint, water injection pipe runs through and mistake from the water filling pore of two packed joints, and air injection pipe then is connected on the gas injection pore, preferably is provided with an airflow cyclotron cavity (2) in the packed joint.
The utility model can use separately, also can use in groups.When using separately the air injection pipe of bottom blocked and get final product, then the gas injection pore between two packers is linked up with air injection pipe when using in groups.
Claims (2)
1, a kind of gasbag-type boring sealing packer, by packed joint, air bag, water injection pipe, air injection pipe constitute up and down, it is characterized in that described air bag is a tubulose, the both ends of pipe are placed in up and down on the packed joint, be equipped with water filling pore and gas injection pore up and down on the packed joint, water injection pipe runs through and mistake from the water filling pore of two joints, and air injection pipe then is connected on the air injection pipe.
2, gasbag-type boring sealing packer as claimed in claim 1 is characterized in that being provided with in the described packed joint airflow cyclotron cavity.
