Abstract
The process of connecting branch pipe to main pipe includes the following steps: pre-fabricating pipe connecting union with one fixing part and one cylindrical part; forming circular hole on main pipe or inspection well with holing machine; roughening and cleaning the contact surface and inserting the connecting union; adhering with fast adhesive to connected the connecting union to the hole; andconnecting the branch pipe with the cylindrical part of the connecting part. The present invention may be used in connecting branch pipe to main pipe in different direction, height and aperture fast and in high quality.
Description
Technical field:
The invention belongs to the technical field of urban construction and environment-friendly engineering, specifically a kind of a kind of manufacturing technology and method that relates to plastic pipe arm connection in the drainage pipeline project construction.
Background technique:
Sewerage system comprises conduit, promotes pumping plant, sewage treatment works etc., and the various sewage in city, waste water, the precipitation of rainy day all must be collected by sewerage system and pipeline, finally handle rightly and dispose.
Traditional drainage pipe adopts concrete pipe or reinforced concrete pipiline, builds the brick inspection shaft of inspection in suitable place, and the maintenance of being convenient to pipeline first is clear and coherent, second is the access point as variant direction, different level pipeline.Conventional concrete pipe self is heavy, and tube coupling is short, inner wall coarse; The flow resistance coefficient is big, need do concrete foundation, long construction period during construction; Brick inspection shaft is from heavy, and the pipeline of especially on the low soft soil foundation of Shanghai foundation bearing capacity, constructing causes sedimentation easily; Cause that interface damages, leaks, serious meeting causes ground to cave in.Along with the continuous appearance and the expansion of novel pipeline material, some plastic materials pipelines begin to substitute the traditional concrete pipeline, and existing drainage pipe commonly used has UPVC pipe, HDPE pipe, PE pipe, Glass Steel Tube, RPM etc.; Such pipeline has from heavy and light, and tube coupling is long, inner wall smooth; The flow resistance coefficient is little; The construction rapid and convenient, plurality of advantages such as comprehensive cost is low more and more receives extensive concern and use.
In the plastic pipe construction at present,, also need build brick inspection inspection shaft in the place that has arm to insert; Still time-consuming, for improving original situation, the integral body inspection inspection shaft that has occurred processing with various materials substitutes brick inspection shaft; Whole inspection shaft has solved the overweight and clear and coherent problem of pipeline of former brick inspection shaft deadweight, but in arm access place, because of in factory, confirming to need to insert the caliber and the absolute altitude of pipeline and insert direction; Can not on pipeline, carry out interface in advance, can only on-the-spot interim perforate on pipeline, arm adopts and directly inserts pipe method simply; Two pipeline joint-seam places connect with expanded rubber or on-the-spot hot weld, but because such pipeline is thin walled tube, two pipeline junctions are merely the line contact but not the face contact; Not only sealing is poor, and the pipeline tension shearing strength of connection is not high yet, and very easily damages.On-the-spot hot weld will be adopted special device, and pipe diameter is big more, and the stress of joint is big more, and damage probability is just big more, usually brings a lot of inconvenience and hidden danger for pipeline construction.
Summary of the invention:
The object of the present invention is to provide a kind of connecting means of improved pipeline branch pipe, it has not only solved different azimuth, different level inserts with the arm of different bores, makes again that the joint surface of contact is big, good airproof performance.
To achieve these goals; Technological scheme of the present invention is: a kind of connecting means of pipeline branch pipe; It is characterized in that: the connecting means of said main pipe arm may further comprise the steps: a, the integral prefabricated pipe joint of elder generation, and link has a fixing part and a cylindrical part; B, leaving circular hole with perforator on the main pipe or on the pit shaft of disjunctor inspection shaft; C, then the pipe joint of corresponding specification is inserted main pipe or adopts link to install to the circular hole of the pit shaft of disjunctor inspection shaft, do the cleaning hacking and handle at the surface of contact place; D, be bonded in hole and link surface of contact place with quick high-strength binder; E, again arm is connected with the cylindrical part of link.
The present invention has been owing to set up pipe joint, both solved the arm access of different azimuth, different level and different bores, impels the surface of contact of main pipe opening joint big again; Good airproof performance, join strength is high, and tension, shear behavior increase substantially; And speed of application is fast, and is simple to operate, do not need know-how and special tool(s); Applied widely, also eliminated construction hidden danger.

Embodiment:
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
The present invention is a kind of connecting means of pipeline branch pipe, it is characterized in that: the connecting means of said main pipe arm may further comprise the steps: a, the integral prefabricated pipe joint of elder generation, and link has a fixing part and a cylindrical part; B, leaving circular hole with perforator on the main pipe or on the pit shaft of disjunctor inspection shaft; C, then the pipe joint of corresponding specification is inserted main pipe or adopts link to install to the circular hole of the pit shaft of disjunctor inspection shaft, do the cleaning hacking and handle at the surface of contact place; D, be bonded in hole and link surface of contact place with quick high-strength binder; E, adopt sealed filling material or rubber pad at hole and link surface of contact place; F and then employing fastening piece are reinforced link; G, again arm is connected with the cylindrical part of link.Be labeled as main pipe 1 in the accompanying drawing, be used for the link 2 that is connected with main pipe, fastening piece 8; The pit shaft 4 of disjunctor inspection shaft, link 2 has a fixing part 5 and a cylindrical part 6 in the enforcement, and the fixing part 5 of link is fixedly connected with cylindrical part 6; This fixing part has a circular-arc internal surface; Cylindrical part is cylindric, and fixing part and cylindrical part are two solids that intersect vertically, and wherein circular-arc internal surface and main pipe cylindrical match; Cylindrical part and arm diameter match, and fixing part is provided with 4-30 fixed hole 7.Specific practice is: in pipeline factory according to different tube diameters, according to regular size generally in the series exploitation of DN200～DN600, integral prefabricated pipe joint (asking for an interview Fig. 1) earlier; The specification of link is DN50～DN2000, and fastening piece quantity is 4～30, and at the scene according to pipe diameter, absolute altitude, the direction at required access point place; (asking for an interview Fig. 2) on the main pipe or on the pit shaft of disjunctor inspection shaft, leaving suitable circular hole with perforator, the pipe joint with corresponding specification inserts installation (asking for an interview Fig. 4) then; Do the cleaning hacking and handle at the surface of contact place; Be bonded in hole and link surface of contact place with quick high-strength binder, if necessary, can adopt sealed filling material such as rubber pad or other simultaneously; For accelerating construction progress, can assist simultaneously and reinforce with corrosion resistant fastening piece 8.Quick high-strength binder wherein is a kind of PVC special bonding agent of having bought on can market.
