Description
Technical field
The present invention relates to a kind of pipe with small pipe diameter plastic drain-pipe jacking construction equipment and plastic drain-pipe pipe jacking construction methods, belong to
In drainage system field, more particularly to the non-excavating construction equipment and construction method of pipe with small pipe diameter drainage pipeline.
Background technology
Municipal drainage is divided into rainwater and sewage, and run-off system is divided into two kinds of separate system and combined system, and most cities are all
Separate system, i.e. rainwater, sewage is taken to discharge respectively.Open cut is usually used in the drainage pipeline at urban construction initial stage, rain sewage diversion
Trench backfill is built road by construction again after pipeline laying.There are many more city, urban construction initial stage due to fund etc. because
Element uses drainage system system, i.e. rain sewage interflow to be directly discharged into river.With urban development, environmental protection consciousness it is strong
Change, sewage need to can just be discharged into river after sewage treatment plant's processing is up to standard, these combined sewerage pipelines need to carry out rain dirt point
Stream transformation, original collecting fitting caliber is larger, is reserved for storm sewer, creates sewage and retains pipeline, will be discharged into collecting fitting originally
Sewage retained from source, then sewage treatment plant is discharged by trunk sewer.Drainage pipeline is transformed in completed region of the city, needs brokenly
Except road, groove is backfilled after being laid with pipeline, restores road surface, project cost is high, influences the road traffic in city.Jacking construction is row
The common construction method of waterpipe is not required to large area and breaks road, it is only necessary in the position of inspection shaft, upper pipe working well and received well are set,
It is smaller to ground traffic impact.
State of the art drainage pipeline jacking construction mainly has earth pressure balance method and mud and water balance method, earth pressure balance method master
It applies in big-diameter pipeline, people can enter pipe operations area and be unearthed.Pipeline less than or equal to 1500mm is mainly flat using muddy water
Weighing apparatus method, in push pipe pipeline front end, the head rotating of installation cuts soil, makes soil pressure by the mud being pressed between head front end and the soil body
The soil of dynamic balance, the jack pushing tow pipeline of active well, head cutting is discharged with mud, and pipeline is pushed up section by section to received well.Muddy water
Balancing method pipe jacking construction technique is ripe, and construction precision is high, but minimum pipe can only jacking diameter 800mm pipeline.
The secondary branch pipe webmaster diameter majority of wastewater interception pipe is 300~600mm, and quantity is most in cutting dirty pipe network, because caliber compared with
It is small to use Sludge-liquid balance method in pipe-jacking construction.The prior art also has a kind of secondary push bench process, can be arranged with 300~600mm of jacking
Waterpipe.Its method is the guide rod of a piece diameter 100mm of first jacking, and guide rod rear end passes through a cone connection installation diameter 200
The unearthed pipe of~250mm, the pipe that is unearthed are pushed up to received well section by section, and spiral of being unearthed is packed into the pipe that is unearthed, and be unearthed pipe rear end fitting machine
Head, head cut soil and are sent forward to received well by spiral of being unearthed.Reinforced concrete pipiline is installed, use is very heavy behind head
Pipeline is pushed up section by section to received well on top.Push pipe head is to transmit top power by pipeline, when encountering complicated geology, it sometimes appear that being machine
Head does not push up received well, and the pipe wall fracture phenomena of rear end haves no alternative but excavate taking-up head in Handpiece Location；Leading portion resistance mistake
Greatly, pushing tow may also result in pipeline protuberance；Unearthed spiral often occur can not be sent out by earth accumulation, cause head load super
It carries.
The prior art also has the practice into pipe with small pipe diameter drainpipe using the mud water balance push bench crown, but caliber is smaller, especially
It is effective most 300mm, 400mm pipelines of sewage, drum diameter also very little, deviation correcting device can not be arranged in head, only
It can be according to the prior push pipe gradient of setting without correction jacking, it is easy to deviation occur beyond the phenomenon that requiring.Mud water balance push bench
Fixation mud flow inlet and scum pipe, it is complicated with the rotating blade muddy water storehouse connection structure of head, in the head of narrow space
It is inside difficult to realize, also limits the use of pipe with small pipe diameter mud water balance push bench.
Drainage pipeline push pipe is all to use armored concrete tubing, and have higher intensity requirement to tubing at present, has been protected
Demonstrate,prove the transmission that power is pushed up in pipeline jack-in process.High-density polyethylene plastics drainage pipe, since inner wall smooth frictional resistance is small, interface
It the advantages that tight non-leakage, corrosion resistance and good, is widely used in drainage pipeline project.Especially caliber 600mm is below
Pipe with small pipe diameter is used widely in sewage conduct.Plastic drain-pipe is embedded in underground, and the ring stiffness of itself can meet top
The requirement of load, but plastic drain-pipe cannot be satisfied the requirement of powerful top power as push pipe tubing, constrain plastic drain pipe
The application in dirty harnessing project is cut in the transformation of old city drainage pipeline, sewage.If the plastic draining of top power can be transmitted by making
Pipe, it is necessary to which the wall thickness for increasing tubing increases the material such as steel of longitudinal stress, to meet the transmission of top power, considerably increases
The cost of tubing, therefore, plastic drain-pipe push pipe are difficult to apply in Practical Project.
