Description
Technical field
The present invention relates to precast assembly pipe gallery, especially a kind of precast assembly pipe gallery socket waterproof construction.
Background technology
City integrated piping lane, also referred to as common trench, integrated pipe canal, are one underground galleries of construction under town road, will
The various municipal pipelines such as electric power, communication, heating power and plumbing are included in the lump, and arrange special access hole, dog-house etc.
Institution.City integrated piping lane unifies implementation management, saves the independent structures of pipeline itself and earth excavation, Ke Yiyou
Effect is intensive to utilize space resources.
The underground pipe gallery of multi-form, its form of fracture, receiving pipeline species, cost, maintenance and management are
It is different.At present, the part underground pipe gallery for building or building, the overwhelming majority adopt cast-type or in factory
Built up by the way of an entirety is transported to job site using being centrifuged or vibrating to pour.All there is certain deficiency in both approaches：
Cast in situs box culvert construct cycle length, high labor intensive, efficiency are low, are affected greatly by weather, field condition, easy to surrounding
The larger pollution of generation, construction quality are also unstable, high cost；The overall box culvert of factorial praluction, piping lane molding time are long, work
Skill complex steps, construction cost are high, and transport, lifting are difficult, especially large-scale box culvert, and production equipment and hanging device input are huge
Greatly, and the box culvert difficulty of super large-scale has production equipment also manufacture.
Therefore, precast assembly pipe gallery arises at the historic moment, and precast assembly pipe gallery is simple to manufacture, flat member transport,
Lifting is convenient, and factorial praluction is quality controllable, and integrated cost is low, can be big relative to concrete tabular component groups dress construction period
It is big to shift to an earlier date, and road is had substantially no effect on, it is applied widely, it is economic and environment-friendly.Due to adopting fabricated construction, the specification of box culvert
Size can be fabricated onto oversize, the external condition such as be no longer limited by manufacturing and transport, solve existing cast-in-place, integral prefabricated
Problem present in technology.But due to be precast assembly be assembled lamellar mounting means, the waterproof of laminated structure lap-joint is asked
Topic it is especially prominent, existing Pipe rack vibrations and other reasonses cause deformation when piping lane bell and spigot at easy leak and affect
Using function.
China Patent Publication No.：CN105525632A discloses a kind of prefabricated pipe gallery bell and spigot waterproof structure
Make, the structure is between previous section bellmouth and latter tube coupling socket using 5 road water proof structure designs.5 described road water proof structures
Including：Water expandable waterstop 1, water expandable waterstop 2, between twice water expandable waterstop inject elastic water-proof material
Stickup waterproof roll at elastic water-proofing material, outer side seam is poured at material, 1 outer gap of water expandable waterstop.The technical scheme
There is certain advance, but unfortunately whole seam crossing all filled with waterproof material, make relatively cumbersome, cost is slightly higher,
It is necessary to improve.
The content of the invention
Based on described above, it is an object of the invention to provide a kind of piping lane bell and spigot waterproof construction of new structure, to change
Enter the deficiency of existing water proof structure, optimize its structure so as to more novelty, practicality, economy.
The present invention is achieved through the following technical solutions：
A kind of precast assembly pipe gallery bell and spigot waterproof construction, including by piping lane socket and connecing that piping lane bellmouth is constituted
Seam, innovation are to be provided with by PCM self-adhered polymer modified bitumen waterproofing membranes, double-component sealing in the seam crossing
Glue, polyethylene filling plate, EPDM wedge-type seal circles, water-swellable elastic rubbery body, the waterproof that self-adhesion adhesive waterproof tape is constituted
Tectosome.
Further, also including injected hole pipe, the injected hole pipe is arranged on piping lane socket, and its opening direction is towards pipe
The inner side of corridor socket.
Further, the double-component fluid sealant is JS-211 type bi-component fluid sealants, and the self-adhesion adhesive waterproof tape is EP
II R type self-adhesion adhesive waterproof tapes.
Further, the one kind of described EPDM wedge-type seals circle for lips wedge-type seal circle.
Further, the EPDM wedge-type seals circle is dehisced outside of the direction towards seam.
Further, in the seam crossing, from the outside of seam to seam, it is disposed with by PCM self-adhering polymers
Modified asphalt waterproof coiled material, double-component fluid sealant, polyethylene filling plate, EPDM wedge-type seal circles, water-swellable elasticity rubber
The water proof structure body that colloid, polyethylene filling plate, double-component fluid sealant, self-adhesion adhesive waterproof tape are constituted.
Further, the PCM self-adhered polymer modified bitumen waterproofing membranes are arranged on the outside of seam, and the self-adhesion is prevented
Glue band is arranged on the inner side of seam.
Further, the setting thickness of the PCM self-adhered polymer modified bitumen waterproofing membranes is 1.5～3.0mm, described
The setting thickness of self-adhesion adhesive waterproof tape is 1.5～2.0mm.
Compared with prior art, the beneficial effects of the present invention is：
1st, EPDM wedge-shaped seal rings are designed using double-lip, and its wedge-shaped design installation resistance is little, can effectively by single lip
Resistance share on 2 lips, be more favorable for installing, sealing effectiveness is more long, and the time is longer；Additionally, two seal lips
Design also solves the phenomenon for being susceptible to mobile rolling when a seal lip is assembled, lips wedge-type seal circle lip height
Size design be higher by 10-20% than the socket of reinforced concrete push pipe, effectively make use of caoutchouc elasticity sealing function, can
Serve the effect of height permanent seal.
2nd, this construction multi layer waterproof is set up defences, outside P CM self-adhered polymer modified bitumen waterproofing membrane in addition to having water-proof function,
Can also anti-plant roots and stems puncture, protect out-seam；Double-component fluid sealant filleting plays waterproof, antiseepage effect；Inner side EPIIR self-adhesions are prevented
Glue band may also operate as the effect of protection against insect, damaged by rats in addition to waterproof, antiseepage, act primarily as the effect of protection inseam, by above-mentioned
Multi layer waterproof, the water proof structure long service life, up to 100 years.
