Abstract
The utility model relates to a forced water testing device for engineering geological prospecting, which is used for measuring the permeability of the underground rock-soil layer, and can also be used for the pressure casting in the layering water level observation and the foundation treatment of the hydrogeologic drill hole. The forced water testing device for engineering geological prospecting is chiefly composed of a pressure meter, a delivery pipe, an air pipe and a filler block assembly. The filler block assembly is communicated with the delivery pipe, and both ends of a capsule are sealed closely by adopting joints and taper sleeves. The delivery pipe forced water testing device for engineering geological prospecting has small diameter, and the forced water testing device for engineering geological prospecting is only provided with 1-2 filler block assemblies. The ordinary pump can be used for inflating the capsule. The forced water testing device for engineering geological prospecting gas light weight, simple structure, and convenient operation, and can be applied in various drill holes whose diameters are 75-150 mm.
Description
The utility model is the packer permeability test device of using in a kind of engineering geologic investigation, in such as engineering geologic investigations such as reservoir, tailing dam, subterranean tunnels, with its permeability of measuring rock-soil layer, also can be used for the layering water-level observation of hydrogeology boring and the slip casing by pressure in the ground processing.
The packer permeability test facility of widely using is a kind of two-tube circulating device at present, and its structure is: one group of inside and outside two-layer water pipe, rubber plunger is equipped with in its lower end, the screw thread capstan winch that leading screw, nut etc. are formed is equipped with in the upper end.During work, the mechanical force extruding rubber plunger that produces by the screw thread capstan winch reaches the purpose of packing examination section so the plunger that expands is close on the hole wall.This device stagnant water effect difference and heaviness." hydrogeological engineering geology " third phase in 1985, reported a kind of packer permeability test device new technology---" the 75S type rope filler block " of Ministry of Metallurgical Industry's prospecting Institute Of Science And Technology, this device mainly contains pressure meter, threeway, flow pipe, tracheae, 2 above filler block assembly, wire rope and winches.The filler block assembly by core pipe, glue assist, joint forms, glue is assisted and is enclosed within the core tube outside, glue is assisted and is communicated with tracheae and be sealed on the core pipe by joint.Several filler block assemblies by the series connection of core pipe together.During work, earlier with winch and wire rope the filler block assembly along putting into boring in the flow pipe, in assisting, glue charges into Compressed Gas with gas compression facility by begging pipe subsequently, just be adjacent to respectively on the flow pipe inwall and on the hole wall of boring so the glue of several expansions is assisted, just reached the purpose of separating the examination section.Like this, when water filling, several up and down filler block assemblies make water enter the examination section by flow pipe by core pipe or floral tube.Compare with two-tube circulating packer permeability test device commonly used, this device stagnant water effect is better, when especially in deep hole, working, the supporting use of cord coring drill of creeping into seems light with being used to hole, but when in the boring of using common drilling tool to creep into, doing packer permeability test, owing to need to be equipped with the bigger flow pipe of diameter, and because the filler block assembly is sent into boring along the flow pipe inner chamber, so glue assists diameter to be restricted, so this device only is suitable for using in diameter is the boring of 75～91mm.
Task of the present utility model is the deficiency that overcomes above-mentioned prior art, provides a kind of simple in structure, easy to operate, the packer permeability test device that all is suitable in big small bore.
Task of the present utility model be achieved in that the filler block assembly by joint, tapered sleeve, clamping cap, glue assist, the core pipe forms, promptly glue is assisted and is enclosed within the core tube outside, the two ends that glue is assisted use tapered sleeve, clamping cap to be connected with joint sealing.Tracheae is assisted by aperture on the joint and glue and is communicated, the lower end of closing water pipe is connected with the core pipe with joint and communicates, the upper end of flow pipe is connected to threeway, pressure meter, for obtaining better sealing effectiveness, it should be a thin ends and thick middle garden tubular that glue is assisted, and joint and tapered sleeve should be intermeshing cone-shaped, during work, Compressed Gas is entered during glue assists by tracheae, and the glue of expansion is assisted and is close on the hole wall, has realized the purpose of packing sealing; Water injects the examination section at last then along threeway, flow pipe, core pipe.
If in the time of will doing the packer permeability test of the examination of the optional position hole in section, only need be below the filler block assembly of said apparatus get final product with floral tube and the tracheae filler block assembly of connecting again.
The utility model is simple in structure, operates lightly, extensively is useful in the boring of diameter 75～150mm and does packer permeability test.
Accompanying drawing has been described two embodiment of the present utility model.
Fig. 1, packer permeability test apparatus structure schematic diagram.
Fig. 2 adopts from top to bottom the packer permeability test device scheme of installation of setting-out piecemeal.
Fig. 3, the packer permeability test device scheme of installation of optional position setting-out in the hole.
Fig. 1 has described the structure of a kind of filler block assembly (10) in the utility model; Glue assists (8) to be enclosed within the outside of core pipe (9), and glue is assisted and communicated with tracheae (4) and with joint (5), tapered sleeve (6), pressure pipe cap (7) sealing.
Fig. 2 has described an embodiment of the present utility model.
When rig puts down when boring to underground from top to bottom, use this device can be at any time at the bottom of the hole examination section do packer permeability test.This device is mainly by flow pipe (3), tracheae (4), and filler block assembly (10) and threeway (2), pressure meter (1) are formed.The flow pipe upper end is connected to threeway, pressure meter, and the lower end connects the filler block assembly.
During work, this device is put into boring make the filler block assembly drop on examination section top at the bottom of the hole, allow the pleasant pipe of Compressed Gas charge into glue and assist, the glue of expansion is assisted and is close to hole wall, and water is by threeway then, and flow pipe and enter the core pipe injects the examination section by core pipe bottom at last.So, by pressure meter, water meter has recorded under certain pressure, flows into the water yield on stratum in the unit interval, just can calculate the permeability of this rock-soil layer.
Fig. 3 has described another embodiment of the present utility model:
This device can be used to do the packer permeability test of optional position in the hole.The difference of itself and embodiment 1 has been two filler block assemblies (10) up and down, and by floral tube (11), tracheae (4) is connected the two series connection together and with flow pipe, and shut with screw plug (12) the core pipe bottom of following filler block assembly.
During work, this device is lowered to boring makes examination section in the core pipe corresponding aperture, then by tracheae up and down the glue of two filler block assemblies charge into Compressed Gas in assisting, so it is isolated that two glue that expand are assisted therebetween examination section and other positions of hole wall, make water enter floral tube by flow pipe through the core pipe of last filler block assembly subsequently, the eyelet from floral tube flows out and injects and try section at last.
