Description
Technical field
The utility model is related to a kind of staggered joint type non-return horizontal reciprocating Grouting Pipe, belongs in construction and mends slurry leakage stopping technology
Field.
Background technology
Trenchless technology refers to, using various drilling and tunneling equipments and technological means, pass through the modes such as guiding, directional drilling
In the case where earth's surface small part is excavated, the construction technique of various underground utilities is laid, changes and repaired.It is rich for weak soil
Water area Deep underground space is used in trenchless technology work progress, generally requires to apply horizontal sealing curtain by horizontal mud jacking
Curtain sets up water proof border, reinforces the excavation face periphery soil body, soil body osmotic coefficient is improved, so as to ensure safe construction and reduce construction
Influence of the process to surrounding enviroment.
, can be to the soil body in certain limit around excavation face in the lasting tunneling process of Deep underground space such as underpass
The larger disturbing influence repeatedly of production so that the horizontal sealing curtain that the last stage applies is iteratively produced a series of crack or even passed through
It is logical, so as to greatly reduce the water isolating of water-stop curtain, reduce it and reinforce effect, endanger the safety progress of construction, and it is right
Periphery construction of structures causes harm.Thus, generally require to carry out repeatedly repeatedly the water-stop curtain body damaged by Grouting Pipe
Repetition mend slurry leak stopping.Due to by factors such as the time of mixing station spice to slip casting, Mortar mix proportion and grout cures times
Blocking occurs in influence, Grouting Pipe.And the Grouting Pipe that previous stage is set often all can not be more the problems such as slip casting hole plug
It is secondary to reuse, new Grouting Pipe can only be squeezed into correspondence position and carries out benefit slurry.Existing Grouting Pipe is due to the defect in structure
Not only waste of materials, also greatly increases workload so that slip casting operation timely and effective can not be carried out.And repeat to squeeze into new note
The process for starching pipe is the further destruction to water-stop curtain again in fact, adds existing discarded conduit and arranges many for new slip casting system
It is restricted so that after the Grouting Pipe that adds each between be hardly formed system and ensure to mend slurry effect, the entirety of slurry is mended in multiple leak stopping
Sealing effectiveness by serious so as to be influenceed.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of staggered joint type non-return horizontal reciprocating Grouting Pipe, can

Further, in order to improve slip casting effect, the aperture of the interior injected hole is more than the aperture of outer injected hole.
Preferably, the aperture of the interior injected hole is outer 1.5 to 2.5 times of injected hole.
Preferably, the length of the outer layer floral tube is 3m, external diameter is 8cm.
Operation principle of the present utility model is, because internal layer floral tube being capable of the movement of opposed outer layer floral tube or rotation, Jiang Yaojin
During row slip casting, moving internal layer floral tube by rotation and push-pull fashion makes outer injected hole and interior injected hole centering, can be achieved with inside and outside
The insertion of injected hole, completes complete opening slip casting；When needing only to starch, rotation and mobile internal layer floral tube make outer injected hole and interior injected hole
Mutual dislocation, you can realize that closed pore stops slurry, when not being arranged sealing grout stop on the outer wall of internal layer floral tube, internal layer floral tube will be outer
Injected hole covering closing, when installing sealing grout stop, outer injected hole is covered and closed by sealing grout stop, better.In closed pore
Under the conditions of non-return, brush pipe is carried out by injecting cleaning fluid to internal layer floral tube, it is ensured that follow-up use requirement.
To sum up, compared with prior art, the beneficial effects of the utility model are：
1st, the utility model can be mutually shifted or be rotated by outer layer floral tube between internal layer floral tube, realize the note of Grouting Pipe
Slurry and only slurry, and can prevent injected hole from being blocked by slurry by cleaning internal layer floral tube, so as to easily realize same
Carry out repeating slip casting in root Grouting Pipe.
2nd, by the utility model, the destruction to water-stop curtain can be reduced to greatest extent during slip casting, it is ensured that
The integral sealing effect of slurry is mended in leak stopping.
3rd, the utility model can save material, reduce man power and material's cost, simplify technique, convenient construction.
