Description

With the PCCP culvert pipe of pre-buried EXPANSION ANCHOR BOLTS steel pipe

Technical field

The utility model relates to a kind of municipal underground pipe network construction culvert pipe, especially a kind of PCCP culvert pipe with the pre-buried EXPANSION ANCHOR BOLTS steel pipe of band of Prestressed concrete cylinder pipe advantage.

Background technique

PCCP pipe is the english abbreviation of Prestressed concrete cylinder pipe (Prestressed Concrete Cylinder Pipe); its structure is being wound around ring orientation prestress steel wire with on the high-strength concrete tube core of steel cylinder; spray is with cement mortar protective course; adopt steel bell and spigot; welded together with steel cylinder; fluted and the cushion rubber of joint socket defines the flexible joint of sliding type cushion rubber; be the composite structure of steel plate, concrete, High Tensile Steel Wire and slush different materials composition, there is steel and concrete characteristic separately.The tubing of the PCCP tubing geometrical shape more any than other of this circle all will save material under equal working condition, the mode of its unique design joint socket flexible connection has certain counter-bending effect, ensure that large diameter pipeline is when being subject to the slight displacement of certain foundation uneven settlement or substantially horizontal, still can keep good sealing, thus increase the reliability of underground pipe network engineering, be the best pipe culvert material of urban construction underground pipe gallery.There is between PCCP Prestressed concrete cylinder pipe the advantages such as reliability is high, long service life, cost are low, pollution-free, easy construction, therefore people wish PCCP to manage these advantages and are applied in large-scale Urban Buried Pipeline Network pipe culvert transformation at present and go very much, particularly wish a kind of be similar to PCCP pipe superior function and PCCP culvert pipe with pre-buried EXPANSION ANCHOR BOLTS steel pipe.

Summary of the invention

For meeting the demand that people build Urban Buried Pipeline Network, the invention provides and a kind ofly be applicable to the PCCP culvert pipe of municipal underground pipe network construction culvert pipe namely with pre-buried EXPANSION ANCHOR BOLTS steel pipe.

The technological scheme that the present invention solves the problems of the technologies described above is: the PCCP culvert pipe of the pre-buried EXPANSION ANCHOR BOLTS steel pipe of described band comprises PCCP prestressed concrete cylinder pipe, EXPANSION ANCHOR BOLTS steel pipe, cable frame, EXPANSION ANCHOR BOLTS, its PCCP prestressed concrete cylinder pipe inside liner of the PCCP culvert pipe of the pre-buried EXPANSION ANCHOR BOLTS steel pipe of described band is embedded with number row EXPANSION ANCHOR BOLTS steel pipe in length and breadth, the inner aperture of its EXPANSION ANCHOR BOLTS steel pipe is slightly larger than aperture, outer end, and its EXPANSION ANCHOR BOLTS steel pipe the inner is equipped with several EXPANSION ANCHOR BOLTS steel pipe feets to steel pipe center of circle external radiation shape.

The inwall of the inner PCCP culvert pipe towards the pre-buried EXPANSION ANCHOR BOLTS steel pipe of band of its pipe of described EXPANSION ANCHOR BOLTS steel pipe, outer end is towards the shaft axis of the PCCP culvert pipe of the pre-buried EXPANSION ANCHOR BOLTS steel pipe of band, and the EXPANSION ANCHOR BOLTS steel pipe outer end mouth of pipe is emerging in the surface of PCCP prestressed concrete cylinder pipe inside liner.

Described PCCP prestressed concrete cylinder pipe comprises protective layer, stress wire, steel cylinder, inside liner.

Described cable frame is fastened on the inwall of the PCCP culvert pipe being with pre-buried EXPANSION ANCHOR BOLTS steel pipe by the EXPANSION ANCHOR BOLTS be placed in EXPANSION ANCHOR BOLTS steel pipe.

The invention has the beneficial effects as follows: the PCCP culvert pipe with pre-buried EXPANSION ANCHOR BOLTS steel pipe a kind ofly has PCCP prestressed concrete cylinder pipe premium properties and the Novel underground PCCP culvert pipe of the advantage such as reliability is high, intensity is large, long service life, cost are low, pollution-free, easy construction, the advantage of its uniqueness effectively can ensure the high quality that Urban Underground pipe gallery is built and long time stability, improves the rank of city opposing flood; Ensure the safety of people's lives and properties; Simultaneously for the pipeline such as electric power, heat supply, feedwater, communication, broadcasting and TV, Zhong Shui, sewage, combustion gas in city must lay, provide a kind of being convenient to and lay, be easy to maintenance, life-span length, safe and reliable Urban Underground pipe gallery building materials; City rainwater drainage etc. all can also be concentrated in this Novel underground PCCP culvert pipe, make city seem more neat and artistic, thus make the happier of people's lives.

Embodiment

As shown in Fig. 1 Fig. 2 Fig. 3: as described in the PCCP culvert pipe of the pre-buried EXPANSION ANCHOR BOLTS steel pipe of band comprise PCCP prestressed concrete cylinder pipe 1, EXPANSION ANCHOR BOLTS steel pipe 6, cable frame 10, EXPANSION ANCHOR BOLTS 20.

As shown in Fig. 2 Fig. 3: as described in PCCP prestressed concrete cylinder pipe 1 inside liner 5 be embedded with number row EXPANSION ANCHOR BOLTS steel pipe 6 in length and breadth, its inner aperture of EXPANSION ANCHOR BOLTS steel pipe 6 is slightly larger than aperture, outer end, and EXPANSION ANCHOR BOLTS steel pipe 6 the inner is equipped with the EXPANSION ANCHOR BOLTS steel pipe feet 7 to steel pipe center of circle external radiation shape, prevent from being pulled out by EXPANSION ANCHOR BOLTS steel pipe 6 when tightening EXPANSION ANCHOR BOLTS 20, cable frame 10 is fastened on the inwall of the PCCP culvert pipe being with pre-buried EXPANSION ANCHOR BOLTS steel pipe by the EXPANSION ANCHOR BOLTS 20 in EXPANSION ANCHOR BOLTS steel pipe 6.

As shown in Figure 3: the inwall of the inner PCCP culvert pipe towards the pre-buried EXPANSION ANCHOR BOLTS steel pipe of band of its pipe of described EXPANSION ANCHOR BOLTS steel pipe 6, outer end is towards the shaft axis of the PCCP culvert pipe of the pre-buried EXPANSION ANCHOR BOLTS steel pipe of band, and the EXPANSION ANCHOR BOLTS steel pipe 6 outer end mouth of pipe is emerging in the surface of PCCP prestressed concrete cylinder pipe 1 inside liner.When the PCCP culvert pipe of the pre-buried EXPANSION ANCHOR BOLTS steel pipe of prefabricated band, by prefabricated for EXPANSION ANCHOR BOLTS steel pipe 6 inwall being embedded in the PCCP culvert pipe tube core being with pre-buried EXPANSION ANCHOR BOLTS steel pipe, the pre-buried location of EXPANSION ANCHOR BOLTS steel pipe 6 of the PCCP culvert pipe namely with pre-buried EXPANSION ANCHOR BOLTS steel pipe.
