Description

Prestressed concrete steel tubing in different shapes

Technical field:

The utility model belongs to concrete duct class, particularly a kind of prestressed concrete steel tubing in different shapes.

Background technique:

In recent years, Urbanization Process In China is advanced by leaps and bounds, high buildings and large mansions in a compact mass have become the scenery in city, but also a series of "urban disease" of association---the urban infrastructure bills dues for a long time such as municipal underground pipe network construction are serious, there are the problems such as insufficient total amount, standard are not high, operation management is extensive while high speed development.Urban waterlogging, water supply gets, pipeline outmoded often the have an accident normal work and life that have affected people, strengthen urban infrastructure construction extremely urgent.Within 2013 2014 2 years, the State Council issues three files: " notice about carrying out the work of municipal drainage prevention waterlogging Facilities Construction ", " suggestion about strengthening urban infrastructure construction ", " instruction about strengthening City Buried Pipeline implementation management ".On December 26th, 2014, the Department of Treasury issued " notice about carrying out the pilot work of state revenue support underground pipe gallery ".

One around " basis, city is established "---the curtain of under ground piping construction pulls open, a collection of Urban Underground pipe gallery and underground storage, sewerage system will be built in 10 years from now on, the construction of these large-sized concrete pipelines in the urgent need to suitable concrete culvert pipe with great for engineering.

Concrete pipe has excellent anti-cracking function and bearing capacity, and construction install convenience, speed are fast, the duration is short, and cheap.Concrete material is corrosion-resistant, long service life, can reach a century, outclass the tubing that steel, plastics or cast iron materials make.

Traditional prestressed concrete pipe comprises circular concrete pipe and special-shaped concrete pipe.

One, its inside and outside profile line of circular concrete pipe is circle, and it is made up of (as shown in Figure 1) concrete tube core 1, mortar cover 2, tube interface seal ring 3 and ring orientation prestress steel wire 4.

The production process of circular prestressed concrete pipe is: making concrete tube core → maintenance → twine and scratch ring orientation prestress steel wire → making ring orientation prestress steel wire mortar cover → maintenance mortar cover → product quality inspection.

Circular prestressed concrete pipe is mainly used in water delivery and pressure conveying sewage conduct, its internal diameter size φ 500 ~ φ 3000mm.

Circular concrete pipe manufacturing process is ripe, convenient for production, structure stress is favourable, materials'use amount is less, and cost is comparatively cheap.But circular concrete pipe uses in the large-scale pipelines such as integrated pipe exterior feature, defeated drainage pipe following shortcoming: arrange in circular cross section that pipeline is convenient not to the utmost, effectively can not utilize space, space availability ratio is low, need to strengthen to the diameter of pipe when making to arrange equal number pipeline in piping lane, thus add engineering cost.Current underground space pipeline is numerous, and planning elevation is limited, and circular round pipes is large to taking of underground space section.

Two, traditional special-shaped concrete culvert pipe with great is non-circular concrete pipe, and its inside and outside profile line is non-circular, and its composition structure is the ordinary reinforced concrete structure of configuration reinforcement in concrete.Common device for shape tubes can change wide, high size, has both met conduit section area requirements, also reaches the object accounting for the underground space less.But this ordinary reinforced concrete structure only sectional dimension of reliable increase component or the method for increase amount of reinforcement improves the bearing capacity of component and carrying out of crackle preventing, obvious this method is not only uneconomical but also must increase the weight of component, and thus the using scope of ordinary reinforced concrete pipe is very limited.

Summary of the invention:

The purpose of this utility model is just the defect overcoming common special-shaped prestressed reinforced concrete pipe, and a kind of prestressed concrete steel tubing in different shapes is provided, this steel tubing in different shapes can meet conduit section area requirement, reduce and take the underground space, improve pipe structure bearing capacity, reduce material consumption, alleviate body weight, and greatly expand applied range.

As above conceive; the technical solution of the utility model is: a kind of prestressed concrete steel tubing in different shapes; comprise concrete tube core and tube interface that inner outline, outer contour or internal and external contour line are non-full circle shape; it is characterized in that: on concrete tube core, be shaped with reinforcement wire, and be shaped with reinforcement wire mortar cover on reinforcement wire surface.

The concrete tube core pressed on ring of above-mentioned non-full circle shape is to being shaped with reinforcement wire.

The concrete tube core pressed on ring of above-mentioned non-full circle shape is all shaped with reinforcement wire to longitudinal.

The concrete tube core of above-mentioned non-full circle shape is box-shaped, three dome-shaped, many circular arcs arch, four dome-shaped, band base shape, porous box-shaped, porous three dome-shaped, porous many circular arcs arch, porous four dome-shaped or endoporus V-shaped.

Above-mentioned tube interface is straight cut, rabbet-shaped interface, steel bellmouth interface, rolled plate bellmouth or socket interface.

Above-mentioned reinforcement wire mortar cover can adopt roll spraying method, gunite, vibratory drilling method or the method that wipes makes.

The concrete tube core pressed on ring of above-mentioned non-full circle shape is to winding reinforcement wire.

The utility model has following advantage and good effect:

1, the utility model can change wide, high size, both can meet the requirement of conduit section area, can reach again the object taking the underground space less.

2, the utility model greatly can improve pipe structure bearing capacity, reduces material consumption, alleviate body weight.

3, the utility model can be used as the service channel of the both sides such as drainage pipe (discharge rainwater, sewage), aqueduct (pressure conduit, free flow water conveyer pipeline), hydraulic engineering pipeline (pressure conduit, high-line conduit), agricultural pipeline, industrial tubes, underground traffic passage, highway crossing (common road, expressway), river course, railway.
