Description
Technical field
The utility model belongs to grout curtain auxiliary device field, is that a kind of power station grout curtain cuts dirt specifically
Drainage tube.
Background technology
Grout curtain is that slurries are poured into crack, the hole of rock mass or soil layer, forms the curtain that continuously blocks water, and is oozed with reducing
Flow and the grouting works for reducing osmotic pressure.
The engineering of seepage proof curtain is built in grout curtain in the rock of gate dam or sand gravel ground using grouting.At the top of curtain
It is connect with concrete gate bottom plate or dam body, the deep opposite impermeable rock stratum certain depth in bottom, with preventing or reduce in ground
The infiltration of lower water；With drainage system collective effect downstream, uplift pressure of the infiltration flow to gate dam can be also reduced.20 generation
Since discipline, grout curtain is always the main means of foundation of hydraulic structure Anti-seeping technology, to ensureing the safety of hydraulic structure
Operation plays an important role.
In filling process, slurries are easily overflowed from grout pipe upper end to be caused, construction environment pollution；To prevent grout pipe upper end
The overflow everywhere of the slurries of spilling opens up an overflow port on grout pipe, for discharging and collecting overflow slurry, still, overflow
Mouthful place's slurries are in the form flow automatically, and slurry flow when is easily precipitated, and overflow port is caused to block.
Utility model content
The utility model aim be intended to provide it is a kind of it is simple and reasonable, effectively can block shadow in overflow by slurries
The power station grout curtain put of rehearsing with musical accompaniment cuts dirty drainage tube.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
A kind of power station grout curtain cuts dirty drainage tube, and including outer tube body, outer tube body upper end side is communicated with overflow
Pipe, the outer tube body upper end are equipped with end cap, and the end cap is from top to bottom inserted with Grouting Pipe, and the Grouting Pipe is fixed with end cap to be connected
It connects, piston is equipped in the outer tube body, the piston is placed on outside Grouting Pipe, the piston and Grouting Pipe airtight connection, the work
Plug and outer tube body airtight connection, the piston upper end are equipped with compressed spring, and the compressed spring is placed on outside Grouting Pipe, the compression
Spring upper end connection end cap, the compressed spring lower end connect piston.
It further limits, restraining position ring block is covered in the Grouting Pipe, the spacing ring is located at below piston.
It further limits, the outer tube body outer wall is equipped with mounting flange.
It further limits, the mounting flange lower face is equipped with gasket.
Using the utility model of above-mentioned technical proposal, a layer concrete layer is poured on stratum in advance, makes to be poured coagulation
The stratum of soil layer has airtight effect, prevents slurries during slip casting from leaching upwards, the pouring effect on lower floor stratum is influenced, then at coagulation
Outer tube body is positioned in hole, outer tube body outer wall is made mutually to be clamped with concrete layer solid for slip casting to earth-boring on soil layer
Fixed, the slip casting into hole by Grouting Pipe, when slip casting, compresses air in hole, and compressed air pushes up piston, simultaneously
The thrust of compressed spring will be overcome, compressed air will build up on certain pressure, when piston is moved to overflow pipe position, compression is empty
Gas carries out pressure release discharge, and compressed spring and bottom slurry act on simultaneously during discharge, and discharge pressure increases；Similarly, when air is arranged
After going out, position that slurries will fill original air, with the increase of grouting amount, the slurry pressure in hole will also increase
Greatly, and piston is pushed up, when piston is moved to overflow pipe position, extra slurries will be total in compressed spring and bottom slurry
It is discharged under the action of by overflow pipe, discharge pressure is big, and flow velocity is fast, slurries can be effectively prevent to precipitate and block up during one stream
The problem of plug.Spacing ring can team's piston position limited, prevent piston from coming off downwards；Mounting flange can be with outer tube body one
Body formed setting can be fixedly connected by fixing pieces such as expansion bolts with mixed mud layer, is prevented grouting pressure excessive and is incited somebody to action outer
Tube body extrudes；In mounting flange lower surface, gasket is set, mounting flange and concrete surface can be sealed by gasket,
Slurries overflow between mounting flange and concrete layer when preventing slip casting.
The utility model compared with prior art, it is simple and reasonable, can effectively slurries be blocked in overflow influence discharge.
Description of the drawings
The utility model can be further illustrated by the nonlimiting examples that attached drawing provides；
Fig. 1 is the structure diagram that a kind of power station grout curtain of the utility model cuts dirty drainage tube；
Main element symbol description is as follows：
Outer tube body 1, overflow pipe 2, end cap 3, Grouting Pipe 4, piston 5, compressed spring 6, spacing ring 7, mounting flange 8, sealing
Pad 9.
Specific embodiment
It is right with reference to the accompanying drawings and examples in order to make those skilled in the art that the utility model may be better understood
Technical solutions of the utility model further illustrate.
As shown in Figure 1, a kind of power station grout curtain cuts dirty drainage tube, including outer tube body 1,1 upper end side of outer tube body connects
Overflow pipe 2 is connected with, 1 upper end of outer tube body is equipped with end cap 3, and end cap 3 is from top to bottom inserted with Grouting Pipe 4, and Grouting Pipe 4 is fixed with end cap 3
Connection, outer tube body 1 is interior to be equipped with piston 5, and piston 5 is placed on outside Grouting Pipe 4, piston 5 and 4 airtight connection of Grouting Pipe, piston 5 and outer tube
