Description
Technical field
The utility model belongs to construction engineering technical field, and in particular to thixotropic slurry is defeated in a kind of push-bench tunneling process
Send pipe lubricant fluid infusion equipment.
Background technology
Main in urban Underground pipeline construction work to carry out set of tunneling construction using two methods, the first is shield
Construction method, second is jacking.
The major way of jacking is to be pushed up prefabricated tube coupling successively to received well from starting well using push-bench
Enter.Because push-bench drum diameter is more than tube coupling diameter, there is certain thickness gap, needed in work progress in tube coupling with ground interlayer
Will be to constantly infusing thixotropic slurry in the gap.Mud plays a part of three aspects, i.e. drag reduction effect, fills up effect and prop up
Support is acted on.Drag reduction effect is slurries parcel tubing, and the dry friction between tube coupling and the soil body is changed into fluid friction, reduces top
Enter resistance；Fill up effect and supporting role be slurries filling tubing and the soil body between gap, hinder the soil body be subjected to displacement.
During jacking construction, in order to thixotropic slurry is transported in the gap between pipeline and stratum, it is necessary to specially match somebody with somebody
A set of slurry transportation system is put, the system is mainly made up of slurrying pond, slush pump, slurry transportation pipeline, and slush pump can
Mud is pumped into the gap that the mud hand-hole reserved on each tube coupling is injected between pipeline and country rock by conveyance conduit.
In the course of conveying of mud, it is mud and conveying in thixotropic slurry course of conveying that slush pump needs the resistance for overcoming
Frictional resistance between pipeline, this resistance is as the length of slurry transportation distance is in nonlinear change.
Theoretically, thixotropic slurry is more thin more is conducive to mud conveying in the duct, can not only reduce mud
The energy ezpenditure of pump, while bentonitic usage amount reduction construction cost during mud can also be reduced.But push pipe in Practical Project
Various stratum are often passed through, formation pore rate, permeability, stability difference are larger.At present because the mud water content commonly used is high,
Solid state component ratio is low, and mobility is strong, belongs to liquid thin pulp, and when the strong soil body of permeability is run into, slurries leakage is big, over the ground
Layer is difficult to form supporting role, causes the sedimentation and deformation on ground, will ultimately result in breakage, surface road, the structure of underground utilities
Build the geological disasters such as deformation, cracking or the destruction of thing.In order to control above-mentioned geological disaster, should be adopted during jacking construction synchronous grouting
Use thick slurry.Thick slurry is conducive to playing filling effect and the supporting role of mud, strata deformation is controlled, while thick slurry can adapt to not
The stratum of same type, even if can also form the mud film of densification in the strong soil body surface of permeability, reduces mud dehydration, to play
Drag reduction acts on offer condition.But this glutinous slurry between hydraulic fill pipeline can produce larger frictional force in course of conveying, it is necessary to
Being equipped with powerful slush pump can meet requirement, this increase that will result in equipment purchasing expense and the increase of energy consumption.
Utility model content
The problems such as in order to solve the cost of equipment and the big energy consumption that are caused due to frictional force increase in thickened drilling fluid course of conveying, this
Utility model provide it is a kind of installed in slurry transportation pipeline junction, can incessantly between mud and duct wall
The fill nipple of even injection lubricant.
For the attainment of one's purpose, the technical scheme of the utility model offer is：
A kind of lubricant fill nipple of push-bench thixotropic slurry conveyance conduit, it include outer tube, unidirectional osmosis pipe and
Internal lining pipe, outer tube is set on unidirectional osmosis pipe, and unidirectional osmosis pipe sleeve is located on internal lining pipe, and the two ends of outer tube are provided with method
Blue disk, overcoat tube wall is provided with lubricant hand-hole, and liner tube wall is provided with several fine and close holes.
Preferably, the ring flange of the outer tube is connected by bolt and rubber anti-leakage pad with the ring flange of slurry transportation pipeline
Connect.
Preferably, described lubricant hand-hole is connected with lubricant delivery pipe.
Lubricant fill nipple of the present utility model can make to form lubricating layer between mud and pipeline, substantially reduce mud
The frictional force for moving in the duct, reduces the energy loss of slush pump.Meanwhile, the length of lubricant fill nipple is small, without
Under conditions of changing original slurry transportation pipeline.Any two section mud can be arranged on by sealing gasket and bolt according to actual conditions
Between slurry delivery pipe.
