Description
Technical field
The utility model relates to the technical field of construction implement device.
Background technology
China's utility model patent number: 200820221416.6 disclose a kind of orifice tube that is used for high hydraulic pressure slip casting, orifice tube is the seamless steel pipe of external diameter Φ 108MM, wall thickness 6MM, length 1.5M, and orifice tube one end welding flange, the other end constitute the blind pipe structure by the cement mortar shutoff; Have the flax silk that twines with the spindle pattern on the tube wall of orifice tube, described orifice tube is positioned at wall for grouting or ends the dark boring of 2.0M on the magmatic rock dish, and is filled with the sulphate aluminium cement slurries between the hole wall of orifice tube and boring.
Under special geologic condition, in tunnel, the grouting leak-stopping during especially big water burst.The device of at present above-mentioned leak stopping is difficult to finish leak stopping in high hydraulic pressure, situation that flow is big.The cost of leak stopping is than higher, and the time of leak stopping is long, and work efficiency is lower.
The utility model content
The utility model purpose aims to provide a kind of grouting leak-stopping device, and this grouting leak-stopping device plugging effect is good, and the leak stopping cost is low, the work efficiency height.
For achieving the above object, the technical solution adopted in the utility model is: a kind of grouting leak-stopping device, comprise orifice tube and film bag, the diameter of described film bag is greater than the diameter of orifice tube, described film bag is enclosed within on the orifice tube, the film bag envelope at described orifice tube two is placed a thin copper pipe between described orifice tube and the film bag on orifice tube.
Described a kind of grouting leak-stopping device, its film bag is identical with the shape of orifice tube, the film bag be shaped as long tubular.
Described a kind of grouting leak-stopping device, the length of its film bag is grown 100 millimeters-150 millimeters than the length of orifice tube.
Described a kind of grouting leak-stopping device, the length of its film bag is grown 125 millimeters than the length of orifice tube.
Described a kind of grouting leak-stopping device, the length of its orifice tube is 900 millimeters.
Described a kind of grouting leak-stopping device, the diameter of its orifice tube is 250 millimeters.
Described a kind of grouting leak-stopping device, the diameter of its thin copper pipe is 20 millimeters.
This grouting leak-stopping device operating principle: carry out orifice tube in advance, the film bag that is a bit larger tham orifice tube with diameter entangles orifice tube then, film bag two ends are tightened, reserve little copper pipe, orifice tube is inserted grout hole, by reserving little steel pipe with handlance injecting glue mud material in orifice tube, after treating the clay material and certain pressure being arranged, block little copper pipe, wait to coagulate.This grouting leak-stopping device has effectively solved the castingin problem at high pressure, big water burst location orifice tube, is used widely in engineering, has played effect preferably.This grouting leak-stopping device can be finished maximum water pressure 3.5MPa, flow is about 900 cubic metres of grouting leak-stoppings hourly.Save the cost and the time of leak stopping, improved work efficiency.
