The causes of pipe blockage in prestressed corrugated pipes

In the construction process of bridge prestressing, the concrete casting construction is often affected by a variety of factors leading to the occurrence of concrete prestressing bellows clogging problem.

The use of prestressed plastic corrugated pipe in the industrial field

The use of prestressed plastic corrugated pipe is relatively large, especially in the field of industrial production. Prestressed plastic corrugated pipe is a new type of pore-forming material with HDPE as the original material. It is important to be used in post-tensioned prestressed cement structure, which is very much used. This pipe has a novel planning and reasonable structure, which breaks through the traditional structure of "plate" of common pipe, so that the pipe has not only the compressive and impact strength, but also the outstanding flexibility. What are the advantages of pre-stressed plastic corrugated pipe?

Advantages and Applications of Prestressed Corrugated Pipe

There are many advantages of prestressed corrugated pipe, which adopts double thread, and its performance indexes such as strengthening stiffness are better than using single thread. It has good bonding with concrete, strong engineering adaptability, and can ensure good quality of the strand orifice, achieve straightness and smooth curve, and its superiority is more prominent for long steel bundles of large span bridges. The pipe friction loss is small. Since the prestressing bellows and steel strand are point contact, the friction coefficient and deviation coefficient of the pipe will also be very small, thus reducing the loss of friction and increasing the effective prestressing force. The friction coefficient of steel strand and pipe wall is 0.16~0.22, the average is 0.19; the deviation coefficient k is (0.6~1.0)x10 a sl., the average is o.8x10 a 3 Zm. The work efficiency of prestressed corrugated pipe is high and the economic benefit is significant. The use of prestressed corrugated pipe can guarantee the quality of the project, and it is easy to operate and easy to pierce the bundle, which can shorten the construction period and save the investment, thus making the economic benefits significantly higher. Prestressed corrugated pipe is very widely used, it is applied to bridges, multi-storey factory buildings, parking lots, office buildings, apartment buildings, gymnasiums and other large buildings. In modern construction, it has been more widely used, it is light, thin-walled, rigid, not broken, no slurry leakage, because of the obvious concave and convex double waves on the exterior of the pipe body, the steel pipe joints are tightly embossed type, firm and not unbuttoned, the contact grip with the concrete is extremely strong after casting on site, and the concrete is formed into a complete one, which enhances the seismic performance of the structure. It has excellent function, compared with the general solid flat slab, it has light self-weight, large span, small deflection, no column cap, good safety, low comprehensive cost, thus improving the building headroom, increasing the use and sales area, compared with the existing domestic ordinary beam-slab structure, solid beamless slab, unbonded prestressed concrete floor slab, not only saves steel, but also saves the amount of concrete, saves vertical water, electricity, air conditioning, elevator, interior and exterior walls It also has the effect of sound and heat insulation, and brings considerable economic benefits to the owner.

What should I pay attention to in prestressing bellows for prestressing test?

The prestressing bellows is tested for prestressing. Because different bellows are deployed with different steel strands, and the same steel strand also has the phenomenon of uneven raw materials, and with regard to the cross-sectional area of the steel strand, there will be a practical deployment of the cross-sectional area of the steel strand is greater than the cross-sectional area of the manipulated tension prestressing test.

The role of metal bellows in major fields and the introduction of performance

Vacuum switch is a switchgear for current flow interruption in vacuum. Its main contact is located in the vacuum interrupter chamber, and the metal bellows is the key element in the vacuum interrupter chamber. Only after using the metal bellows is it possible to make the contact movement from outside the vacuum interrupter chamber by mechanical force and keep the vacuum interrupter chamber shell completely sealed.
