Abstract

With the PCCP culvert pipe of pre-buried weldment, it is characterized in that: its PCCP prestressed concrete cylinder pipe inside liner of the PCCP culvert pipe with pre-buried weldment is embedded with the pre-buried weldment of number row in length and breadth, and cable frame comes into line on the pre-buried weldment of the inwall being weldingly fixed on the PCCP culvert pipe being with pre-buried weldment respectively in length and breadth.Cable frame can lay urban electric power cable, communication cable, water supply line, its each pipe joint can reach the twist of about 3 °, and guarantee not have leakage, the landform therefore caused in anti-uneven settlement, anti-flood move horizontally and antiseismic etc. in than portland cement pipe, below culverts, Underground Culvert, system culvert is built at scene, underground just obvious advantage.And making that same cross-sectional is amassed, the culvert pipe of identical working pressure operating mode time, circular Novel underground PCCP culvert pipe than portland cement pipe, below culverts, Underground Culvert, scene, underground build system culvert and all save cost.

Description

With the PCCP culvert pipe of pre-buried weldment

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 weldment 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 weldment.

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 weldment.

The technological scheme that the present invention solves the problems of the technologies described above is: the PCCP culvert pipe of the pre-buried weldment of described band comprises PCCP prestressed concrete cylinder pipe, pre-buried weldment, cable frame, its PCCP prestressed concrete cylinder pipe inside liner of the PCCP culvert pipe of the pre-buried weldment of described band is embedded with the pre-buried weldment of number row in length and breadth, its pre-buried weldment one end is little square tabular, and its other end is large square tabular.

Described pre-buried weldment its be little square tabular one end towards the PCCP culvert pipe steel cylinder direction of the pre-buried weldment of band, it is the shaft axis of one end towards the PCCP culvert of the pre-buried weldment of band of large square tabular, and pre-buried weldment is that one end emerges on top of large square tabular is on 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 comes into line on the pre-buried weldment of the inwall being weldingly fixed on the PCCP culvert pipe being with pre-buried weldment respectively in length and breadth.

The invention has the beneficial effects as follows: the PCCP culvert pipe with pre-buried weldment 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 weldment of band comprise PCCP prestressed concrete cylinder pipe 1, pre-buried weldment 6, cable frame 10.

As shown in Fig. 2 Fig. 3 Fig. 4: as described in its PCCP prestressed concrete cylinder pipe 1 inside liner of PCCP culvert pipe of the pre-buried weldment of band be embedded with the pre-buried weldment 6 of number row in length and breadth, its pre-buried weldment 6 one end is little square tabular, its the other end is large square tabular, described pre-buried weldment 6 its be little square tabular one end towards PCCP culvert pipe steel cylinder 4 direction of the pre-buried weldment of band, it is the shaft axis of one end towards the PCCP culvert of the pre-buried weldment of band of large square tabular, pre-buried weldment 6 one end is that the emerges on top of large square tabular is on the surface of PCCP prestressed concrete cylinder pipe inside liner 5, cable frame 10 is welded on pre-buried weldment 6.

As shown in Fig. 1 Fig. 2: as described in PCCP prestressed concrete cylinder pipe 1 comprise protective layer 2, stress wire 3, steel cylinder 4, inside liner 5.

As shown in Fig. 2 Fig. 3: as described in cable frame 10 come into line in length and breadth on the pre-buried weldment 6 of the inwall being weldingly fixed on the PCCP culvert pipe being with pre-buried weldment respectively.

The PCCP culvert pipe remarkable advantage of the pre-buried weldment of the utility model band is: under the PCCP culvert pipe with pre-buried weldment bears the situation of pressure in pipe, each pipe joint can bear the windup-degree of 1 °-3 °, and guarantee not have leakage, the landform therefore caused in anti-uneven settlement, anti-flood move horizontally and antiseismic etc. in than portland cement pipe, below culverts, Underground Culvert, system culvert is built at scene, underground just obvious advantage; And making that same cross-sectional is amassed, the culvert pipe of identical working pressure operating mode time, the PCCP culvert pipe of the circular pre-buried weldment of band than portland cement pipe, below culverts, Underground Culvert, underground steel to contain and scene, underground is built and made, builds culvert and all save cost, be that Urban Underground pipe gallery builds best building materials.
