Abstract
A kind of grouting aperture locking device, belongs to the provisions for grouting in construction of hydropower facilities engineering.It comprises sealer and orifice tube, and inlet pipe, return pipe and outlet pipe are installed on sealer, and its key technology is in sealer lower end and orifice tube top welded and installed connector respectively, and connector adopts cutting ferrule to connect.The beneficial effect the utlity model has is: be connected because sealer and orifice tube adopt cutting ferrule, simple in structure, install convenient, shorten the locking device set-up time, in bad ground Grout-jetting pipe grouting construction, avoid locking device rotation to install Grout-jetting pipe has been caused to the defects such as distortion knotting even fractures, can not cause plugging pipelines, guarantee that slurries are recurrent state in hole, make to be in the milk normally, to carry out in an orderly manner, accelerating construction progress, ensures grouting quality effectively.
Description
Technical field:
A kind of grouting aperture locking device, belongs to the provisions for grouting in construction of hydropower facilities engineering.
Background technology:
At present, all adopt Grout-jetting pipe to be in the milk at deep hole and bad ground, the sealer of its aperture locking device adopts the revolving joints such as screw thread to be connected with orifice tube.There is following shortcoming in this device: 1, because revolving joints such as adopting screw thread comes connecting sealed device and orifice tube, when installation, Grout-jetting pipe easily rotates in orifice closure, the easy distortion knotting of Grout-jetting pipe even fractures, cause plugging pipelines, slurries cannot circulate, slurries precipitate rapidly, the serious consequence in shutoff crack, and grouting quality is caused a hidden trouble.2, due to grouting complex geologic conditions, in boring procedure, drilling rod disturbance easily causes orifice tube distortion or destroys silk mouthful, and cement calculus can be filled silking, and aperture locking device is installed difficulty, and cleaning difficulty is large.3, rig top presses aperture locking device not tolerate high pressure, easily spillage.
Summary of the invention:
Problem to be solved in the utility model is exactly that a kind of grouting aperture locking device of avoiding rotation to install is provided for above deficiency.Its technical scheme is as follows:
It comprises sealer and orifice tube, and inlet pipe, return pipe and outlet pipe are installed on sealer, and its key technology is in sealer lower end and orifice tube top welded and installed connector respectively, and connector adopts cutting ferrule to connect.
In described cutting ferrule, rubber gasket is set.
Described cutting ferrule adopts bolt to link closely.
Compared with prior art, the beneficial effect the utlity model has is:
1, because adopting cutting ferrule, sealer and orifice tube be connected, simple in structure, install convenient, shorten the locking device set-up time, in bad ground Grout-jetting pipe grouting construction, avoid locking device rotation to install Grout-jetting pipe has been caused to the defects such as distortion knotting even fractures, can not cause plugging pipelines, guarantee that slurries are recurrent state in hole, make to be in the milk normally, to carry out in an orderly manner, accelerating construction progress, ensures grouting quality effectively.
2, in cutting ferrule, settle rubber gasket, sealing effect is good, non-leakage under pressure, can tolerate high pressure, is subject to cement grout calculus and boring drilling rod disturbing influence little, improves construction efficiency.
3,, due to above structure, the utility model product is durable in use.
Brief description of the drawings:
Fig. 1 is the utility model sealer structural representation;
Fig. 2 is the utility model orifice tube structural representation;
Fig. 3 is the utility model ferrule structure schematic diagram.
Detailed description of the invention:
Referring to Fig. 1-Fig. 3, the utility model comprises sealer 1 and orifice tube 6, and inlet pipe 4, return pipe 3 and outlet pipe 5 are installed on sealer 1.Its key technology is in sealer 1 lower end and orifice tube 6 tops welded and installed connector 2 respectively, and connector 2 adopts cutting ferrule 7 to connect.Must full section welding while being welded to connect, can not spot welding or rosin joint.
The interior rubber gasket 8 that arranges of described cutting ferrule 7, to reach non-leakage effect under high pressure.
Described cutting ferrule 7 adopts bolt to link closely.
When use, grout outlet 5 is connected with Grout-jetting pipe docking, adopts iron wire binding.
Its construction method is as follows:
1, sequence of construction, at aperture pipeline section setting-out, the rear castingin orifice tube of grouting, is treated solidifying 48h routinely.
2, after grout compartment has been holed, underlying Grout-jetting pipe, Grout-jetting pipe is not more than 0.5m at the bottom of apart from hole.Top colligation is on sealer outlet pipe.
3, adopt cutting ferrule spiral-lock aperture locking device, fastening bolt when setting-out, grouting.After installing, adopt wooden stick to rap aperture locking device, check and whether install firmly.
Claims (3)
1. a grouting aperture locking device, comprise sealer (1) and orifice tube (6), at upper inlet pipe (4), return pipe (3) and the outlet pipe (5) installed of sealer (1), it is characterized in that in sealer (1) lower end and orifice tube (6) top welded and installed connector (2) respectively, connector (2) adopts cutting ferrule (7) to connect.
2. aperture locking device is used in grouting according to claim 1, it is characterized in that arranging in cutting ferrule (7) rubber gasket (8).
