Abstract
The utility model discloses a kind of advanced conduit ball-valve type joint of constructing tunnel grouting methol.It is to fix Grouting Pipe in the side of conical shape check valve, opposite side hinge electron adsorption device, the valve ball that returns that its external diameter is more than to slip casting bore is positioned in the empty room of conical shape check valve, advanced conduit is placed in electron adsorption device, conical shape check valve is inserted radially into some check levers, sealing ring, sealing ring sidepiece installation Spring Card are installed between electron adsorption device and advanced conduit.The utility model overcomes the problem of current advanced pipe guide of constructing tunnel grouting methol is present, using low-voltage electronic strong absorber, that is energy-saving safe, installation is quick, it is again easy to operate, construction quality has been ensured again simultaneously, efficiency of construction has been greatly improved, is a kind of comparatively ideal constructing tunnel conduit grouting device for meeting demand of technical standard.
Description
Technical field
It the utility model is related to a kind of jointing device that the advanced conduit of grouting methol is carried out in constructing tunnel, tool
Body is a kind of advanced conduit ball-valve type joint of constructing tunnel grouting methol, belongs to road and bridge construction field.
Background technology
Road infrastructure construction at present has been enter into the global high speed development stage, and constructing tunnel is road construction
Key link, both require construction safely and fast, while required energy-conserving and environment-protective again, and mitigate the labor intensity of workmen.
If run into constructing tunnel geological structure it is poor when it is necessary to the chapelet face periphery in excavation squeeze into more advanced conduit,
It is that can explore rock texture situation above that it, which acts on one, and two are for grouting methol in every advanced conduit, is made advanced
Conduit closely links into an integrated entity with rock, is easy to the safety and stability of postorder excavation construction.Advanced conduit pressure injection cement is given at present
Starch the following two methods of generally use：When be first connected to advanced tube at one end processing screw thread with ball valve, while in the another of ball valve
The steel pipe to match with Grouting Pipe is installed in one end, ball valve is closed after advanced conduit grouting methol, then lead in advance to next
Pipe grouting methol, until all advanced conduit grouting methol completions, because cement mortar can not be dismantled immediately before initial set, it must treat
The movable ball valve of ability is dismantled after several hours, so influenceing construction progress；Also one kind is not mounting ball valve, be treat it is advanced
Dismantled after the complete cement mortar of conduit pressure injection Grouting Pipe, then clog duct inlet with cloth or plastic paper, because manifold pressure is larger,
So having some when dismantling Grouting Pipe, completely pre-hardening cement mortar does not eject, and causes potential safety hazard.Other ball valve
Construction is more complicated, and disassembly, cleaning are difficult, and scrappage is very high, significantly increases construction cost, reduces efficiency of construction.At present still
Have no the device of the comparatively ideal advanced conduit of constructing tunnel grouting methol.
Utility model content
The purpose of this utility model is the problem of overcoming the current advanced pipe guide of constructing tunnel grouting methol to exist, from
And disclose a kind of advanced conduit ball-valve type joint of constructing tunnel grouting methol.
The technical solution of the utility model is as follows：
Grouting Pipe is fixed in the side of conical shape check valve, will in its opposite side by connecting hinge hinge electron adsorption device
The valve ball that returns that its external diameter is more than slip casting bore is positioned in the empty room of conical shape check valve, then advanced conduit is placed in into electron adsorption
In device, conical shape check valve is inserted radially into some check levers, and it be 1-2cm to go back to the laterally movable gap of valve ball, in electron adsorption device and
Sealing ring, sealing ring sidepiece installation Spring Card are installed between advanced conduit.
The utility model overcomes the problem of current advanced pipe guide of constructing tunnel grouting methol is present, using low electricity
Pressure force electron adsorption device, i.e. energy-saving safe, installation is quick, and easy to operate, while has ensured construction quality again, greatly carries
High efficiency of construction, is a kind of comparatively ideal constructing tunnel conduit grouting device for meeting demand of technical standard.
Brief description of the drawings
Accompanying drawing 1 is front view structure diagrammatic cross-section of the present utility model.
Accompanying drawing 2 for the utility model accompanying drawing 1 A-A to left view diagrammatic cross-section.
Accompanying drawing 3 is the B-B direction left view diagrammatic cross-section of the utility model accompanying drawing 1.
Reference is as follows：Grouting Pipe 1, return valve ball 2, conical shape check valve 3, check lever 4, Spring Card 5, sealing ring 6, connection
Loose-leaf 7, electron adsorption device 8, advanced conduit 9.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing：
Grouting Pipe 1 is fixed in the side of conical shape check valve 3, passes through the hinge electron adsorption device of connecting hinge 7 in its opposite side
8, the valve ball 2 that returns that its external diameter is more than to the internal diameter of Grouting Pipe 1 is positioned in the empty room of conical shape check valve 3, then advanced conduit 9 is placed in
In electron adsorption device 8, conical shape check valve 3 is inserted radially into three check levers 4, and it is 1.5cm to go back to the laterally movable gap of valve ball, in electronics
Sealing ring 6, the sidepiece of sealing ring 6 installation Spring Card 5 are installed between absorber 8 and advanced conduit 9.
The utility model operate when first advanced conduit is put into electron adsorption device, then start electron adsorption device make its with
Advanced conduit absorption is held tightly, and slip casting machine connects slip casting flexible pipe and starts to carry out advanced conduit slip casting again, and built-in returns valve ball automatically
Cement mortar can be made, and stream is mapped in grouting pipe and rock crevice glibly.Slip casting machine release after the completion of slip casting is treated, returning valve ball will
Self-closed grouting port prevents cement mortar from ejecting, to initial set after the completion of close low-voltage power switch, close electron adsorption
Device, electron adsorption device are separated with advanced conduit, and advanced conduit is removed out of electron adsorption device, are led in advance to multiple by that analogy
Pipe carries out slip casting.The utility model can be easily removed after all advanced conduit cement mortars fill, next time is standby after cleaning.
