Description

For the sliceable pipe fitting of the compound pipe gallery of bamboo and the piping lane including the pipe fitting
Technical field
The invention belongs to piping lane technical field, and in particular, to a kind of sliceable pipe fitting for the compound pipe gallery of bamboo And the piping lane including the pipe fitting.
Background technology
Piping lane is to be built in the urban operating mechanism that Urban Underground is used to lay municipal pipeline.Its collect electric power, communication, broadcasting and TV, combustion gas, A variety of municipal pipelines such as plumbing, heating power efficiently utilize the space under road in one, save Underground Space Resource, Prevent each special pipelines irregularly to excavate respectively, influence, thoroughly solves " road caused by road and surrounding enviroment The problems such as slide fastener ", " aerial cobweb ".
Existing piping lane generally use reinforced concrete structure is prepared by cast-in-place or prefabrication system, this piping lane one Aspect consuming material is more, and construction is big, long construction period, and cost is high, on the other hand its Reinforced Concrete Materials used Energy consumption is big, causes largely to discharge in production process, and effect on environment is very big, is increasingly difficult in adapt to energy-saving and emission-reduction and modern times Change the demand of urban construction.
To overcome drawbacks described above, occur the piping lane of new material preparation, such as applicant's earlier application in the prior art Patent CN 205136858U disclose a kind of compound piping lane of prefabricated bamboo, wherein the structure sheaf of tube coupling of composition piping lane is largely adopted Prepared with bamboo wood material.Specifically, which radially includes liner layer, structure sheaf and external protection coating, the liner successively from the inside to the outside Layer include flame-retarded resin and flame-retardant textile, if the structure sheaf include at least dried layer by be stained with water-soluble resin thin bamboo strips used for weaving winding and Into thin bamboo strips used for weaving layer, which includes at least flame-retarded resin, which is fixed on the inner surface of the tube body.Due to pipe Corridor pipe structure layer is made of thin bamboo strips used for weaving so that tube body and its to manufacture process environmentally protective, while proof strength, and matter Amount is light, transports and easy for installation, and bamboo is renewable resource, and the cost of raw material is low.This piping lane overcomes current reinforcing bar and mixes Xtah Crude Clay structure piping lane is existing to expend that material is more, and construction is big, long construction period, cost is high and energy consumption and discharge it is big, The defects of not recyclable and degraded.
Because piping lane internal diameter is larger, even up to 8-10m, and be embedded in underground and accommodate various pipeline pipelines, including Various water, electricity even combustion gas etc., except very high outer to the requirement of its integral strength, have very high want to the barrier propterty of piping lane Ask, to ensure the safety of pipeline pipeline.In such scheme, although wherein having been used in liner layer and external protection coating fire-retardant anti- Fiery material, structure sheaf therein can ensure certain fire protecting performance also by by adding fireproof resin or filler.But Because bamboo wood combustibility is stronger, however it remains possible fire prevention risk, particularly wherein liner layer, itself and internal pipeline pipeline And bamboo wood directly contacts in structure sheaf, its effective fire protecting performance is very crucial, and the fire prevention in such scheme to liner layer is only It is by flame-retardant textile and flame-retarded resin, its flameproof effect still has deficiency, in addition, the knot of this liner layer and structure sheaf Conjunction property can also have an impact tube body intensity, it is necessary to the further bonding tightness of lifting liner layer and structure sheaf.
The content of the invention
For more than the prior art deficiency or Improvement requirement, the present invention provide it is a kind of for bamboo compound pipe gallery can Splice pipe fitting and the piping lane including the pipe fitting, it passes through the improvement to pipe fitting liner layer material and corresponding construction so that preparation Liner layer and pipe fitting have excellent fire protecting performance, while improve pipe fitting intensity.
