Description
Technical field
Underground pipeline construction technology of the present invention specifically belongs to a kind of heavy caliber length apart from steel jacking construction system.
Background technique
Push pipe is a kind of pipeline construction technology of non-excavation, and the hydraulic pressure jacking equipment through in the wings is with the jacking forward of underground pipeline.Long-distance pipe jacking refers generally to the jacking distance and surpasses the above push pipe of 400m.The large-diameter steel push pipe refers generally to surpassed by the jacking pipe diameter push pipe of 2.5m, is steel pipe by the jacking pipe material.General underground pipe-driving survey adopts laser alignement technique, and the laser guide action radius has only 300m, can only adopt manual measurement above behind the 300m, need interrupt jacking during measurement, and not only efficient is low, and the human error occurs easily.The present invention uses automatic electronic tachometer, and through the automatic measurement of computer control realization efficiently and accurately, action radius can reach 1500m.
Large-diameter steel pipe bending deflection difficulty, the jacking direction is wayward, deviation appears and after, direction out of control often appears in the correction difficulty in the construction, cause the engineering loss.The present invention is provided with 3 joint transition tube between at pipe jacking tunnelling machine and by the steel pipe of jacking, and 3 joint transition tube are flexible and the jacking direction is returned during correction, solved the difficulty of steel pipe jacking.
General heavy caliber pipe-jacking is laid track in pipeline, carry the earth under excavating with vehicle, and efficient is extremely low.Earth becomes mud so also have into, carry through centrifugal pump, hydraulic fill pipeline system, but this method need consume a large amount of construction waters, and produce a large amount of waste gas mud, and directly discharging will cause environment and have a strong impact on, and the processed cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of heavy caliber length apart from steel jacking construction system; In pipeline the place ahead the piston type transfer pump is installed,, is grown distances through pipeline with the stream plasticity earth that screw conveyor transfers out; Efficient is very high, overcomes the shortcoming of vehicle conveying and slurry transportation mode.
Technological scheme of the present invention is following:
A kind of heavy caliber length is apart from steel jacking construction system; The steel push pipe is positioned at the excavation hole of packing into, and the place ahead at excavation hole is provided with pipe jacking tunnelling machine, and steel push pipe front end top is shaped on a plurality of transition tube; Be placed with defeated dredge pump in the transition tube; The import of defeated dredge pump is connected with screw conveyor, and outlet is connected with defeated dredge pump pipe, and the end of defeated dredge pump pipe extend into ground storage basin; Steel push pipe rear end is provided with main jack, and main jack rear side overhead is equipped with a plurality of arched top iron, circular top iron between main jack and the steel push pipe rear end on reacting wall.
The below of described a plurality of arched top iron is equipped with the guide rail that is slidingly installed with it.
Described excavation is provided with mudjack in the hole, and the mud jacking rest of mudjack input the steel push pipe, and mudjack is connecting the thixotropic slurry system outward.
Described pipe jacking tunnelling machine is provided with the target prism, is fixed with six orientation by backsight prisms on the sidewall of active well respectively.
Long-distance pipe jacking is measured guidance system and mainly is made up of automatic measurement electronic tachometer, industrial computer, data radio, target prism, directional prism; Can measure automatically misalignment of axe, angle of rotation, pitching angle, the deviation adjustment angle of move speed, push-bench; Need not stop construction; At any time lead, 6 directional prisms are fixed on EXPANSION ANCHOR BOLTS on the borehole wall of active well, and are symmetrical as far as possible with respect to the jacking axis.The height that directional prism is arranged must be convenient to ground and the down-hole guidance system is measured.
The spoir level is transported in the general heavy caliber earth pressure balance push pipe pipe, adopts the mode of the rail transport of storage battery car traction more.But the temporary transient jacking construction that interrupts of this mode needs, efficient is extremely low in growing apart from jacking construction, will seriously restrict speed of application.So in this engineering; The mode of pipeline pumping is adopted in earthwork transportation in the pipeline, and this pump can directly pump the soft shape earth of moulding, and does not need extra water when too hard (be unearthed too dried can in hopper, add low amounts of water) that adds; The soil that pumps is convenient to deposit and transport outward than mud; Practiced thrift cost greatly, the soil of the defeated native machine output of spiral directly gets in the hopper of concrete pump, directly is pumped in the mud pit of ground by concrete pump.
Because adopt the low-voltage power supply of common 380V in the jacking distance, pipeline, the greatest problem that faces is exactly that power supply line can produce very big pressure drop, thereby these equipment can't be run well or damage.Therefore must take to increase power supply line's sectional area and set up the power circuit stable-pressure device, cause the difficulty of interior advancing equipment of pipeline and cable so again.Jacking construction can not adopt the mode of high voltage supply because the space is limited as shield-tunneling construction.In order to solve these difficult problems, on ground booster is set voltage is risen to 660V from 380V, be delivered to pipe jacking tunnelling machine through cable again.
Compared with present technology, beneficial effect of the present invention is following:
1, uses automatic electronic tachometer to form and measure guidance system guide jacking direction automatically.
2, use earth pressure balance pipe jacking tunnelling machine mining clay, screw conveyor is sent to transfer pump with earth then, and oily transfer pump is delivered to ground with earth through pipeline mounted pump.
3, push-bench and be provided with between the jacking steel pipe 3 the joint transition tube, be convenient to control the jacking direction.
4, through the low power supply system of 660V, to the pipe jacking tunnelling machine transmitting power.
