Internal bonded tendons – where one or more strands are inserted into a metal or plastic duct that is embedded in the concrete. By filling the duct with special grout, the tendon is `bonded` with the surrounding concrete. Internal bonded tendons are installed before concrete is poured and become locked in concrete. This approach is often used for bridges and heavily loaded beams in buildings – flat internal systems are also an excellent choice for thin slabs.

In addition to the appearance , it is necessary to touch the hand personally feel the geotextile compactness.Generally, the mass with high compactness will exceed that with low compactness, and the density of geotextile obviously affects the quality of geotextile.Laboratory test method: it is an accurate and convenient method to take a sample of short wire geotextile and send it to the laboratory for testing. Laboratory test can determine the parameters related to geotextile such as breaking strength index, elongation index and CBR bursting strength index of short wire geotextile.Customers can compare their own engineering construction parameter requirements from these indicators, geotextile is not qualified on the obvious.

For geotextile appearance inspection, we first look of the appearance of short silk geotextile. What people's eyes see is real, especially experienced procurement and inspection personnel, who can usually judge the quality of geotextile to some extent by their eyes.The short silk geotextile with same quality standard, color is pure white and do not have makings dot, so we can judge it is the better short silk geotextile.

On the morning of September 11th, Africa investment and trade fair meeting is held in our city.This annual seminar is hosted by the people's government of Quzhou City and CCPIT,Quzhou City international chamber of commerce, Quzhou City "One Belt And One Road" trade and investment promotion center, Quzhou green industry agglomeration area management committee, Quzhou City foreign affairs and overseas Chinese affairs office of the district management committee, The angolan embassy in China, consulate general of the republic of South Africa in Shanghai, South Africa marplan plus, zhejiang province economic development, the central African economic and cultural exchange center in collaboration with the common organization. We have introduced PP nonwoven geotextile, PET nonwoven geotextile, PVC pipe, HDPE water pipe, post tensioning galvanzied duct, prestressed plastic duct and perforated sprial pipe, for them to build their country. Currently, our country is getting better and we have many cooperation with Africa to get common prosperity .

One of the major advancements in bridge and deck construction in the world was the development and use of prestressed concrete. Made possible through the use of post-tensioned steel cables run through post-tension ducts, this construction method enables thinner concrete sections, longer spans between supports, stiffer walls to resist lateral loads, and stiffer concrete deck sections. Post tension round and flat corrugated duct is roll formed by the GI steel strip, with its special corrugations and high radial stiffness. The corrugated tubes meet with structural design specifications for void former in concrete structures, used to reduce the cross section area and thus the weight of the structure. It is a very rigid but yet light weight sheet metal tubing that without excessive deforming, withstands existing forces during the pouring of the concrete. The spiral seam is tight and no water from the concrete will enter the tube. The low weight of the tubing makes it easy to handle. On many construction projects like apartment buildings, parking garages, office buildings, industrial buildings, bridges and docks, schools and hospitals, the introduction of the prestressed protection tubes will make it possible to use very long spans. The reduction in weight allows large areas and fewer columns which in turn will give technical economical and esthetic advantage.

Post tensioning is a technology for ferroconcrete project. Post-tensioning steel strand tendons, which are put inside prestressing plastic ducts, metal ducts or sleeves, are positioned in the forms before the concrete is placed. Before the service loads are applied, once the concrete has gained strength, the cables are pulled tight, or tensioned, and anchored against the outer edges of the concrete. Post-tensioning is a kind of form of prestressing. Prestressing simply means that the steel is stressed similar as pulled or tensioned, before the concrete has to support the service loads. Most precast, prestressed concrete is actually pre-tensioned-the steel is pulled before the concrete is poured. Post-tensioned concrete means that the concrete is poured and then the tension is applied-but it is still stressed before the loads are applied so it is still prestressed.

Geotextiles are permeable fabrics. Construction Nonwoven Fabric when used in association with soil, have the ability to separate, filter, reinforce, protect or drain. While a number of generic classes of geotech textile are manufactured, by far the most popular Polypropylene Nonwoven Fabric is the needle punched style of product due to its versitility and overall performance. Paving fabric is nonwoven geotextile which prolongs road life, reduces overlay thickness, prevents water ingress and retards reflective cracking.sub soil drainage systems construction nonwoven fabric used to remove water from road works or sports fields and behind retaining walls.The high porosity of the geofabrics allows water flow while preventing fines migration.

With the development of modern industrial technology, houses can be built in batches, just like machines.As long as the prefabricated building components, shipped to the site to be assembled. A large number of building parts are produced and processed by the workshop, and the components are mainly: exterior wall panels, interior wall panels, laminated boards, balconies, air-conditioning boards, stairs, precast beams, precast columns, etc. It needs oblate pre-stressed metal corrugated pipe, circular pre-stressed metal sewage pipe or circular pre-stressed plastic corrugated pipe/tube. Those ducts should be prepared before structure form work and concreting. It adopts the integrated design and construction of architecture and decoration, and the ideal state is that decoration can be carried out synchronously with the main construction. The standardization of design and management of information, the standard components, the production efficiency is higher, the corresponding component costs will fall, cooperate with the digital management of the factory, the prefabricated construction will be more and more affordable.

Maybe someone will think what influence the price of geotextile? Geotextile has excellent permeability, filterability, durability, acid and alkali resistance and corrosion resistant. Non woven geotextile can be widely used in railway, highway, sports hall, dams, hydraulic structure, tunnel, coastal mud flat, reclamation, environmental protection and other projects. Generally, there are three colors of geotextile, white, black,gray and there are no difference from the function and the price are all same. However, recycle material or raw material, gram weight ,strength of the geomaterials effects the fabric price. Recycle material will effect the service life and may be the strength is not ideally as raw material geotextile, but the price is very charming. At the top of underground garage, generally need to do waterproof and drainage engineering,on the flat floor need to lay drainage plate,then spread a layer of geotextile on the drainage plate. The function of geotextile is protection and filtering, can filter sediment into the drainage plate, and can protect the drainage plate, then covering the soil. The process of general roof greening construction is the same.

What is geotextile? Geotextile is a kind of textiles or called non woven fabric. Textiles are cloths and fabrics made from weavable fibers. We use textiles in our daily life ,such as clothing, bedding, decoration. However, When textiles made to geotextile, it can be used in agriculture and ecosystem management. we use permeable fabrics geotextiles to help control erosion and maintain soil stability. Since the 1950s, we've used synthetic polymers to create modern geotextile. Geotextile are applied to the soil or road, non woven geotextile is designed with the specific intent of improving or managing the soil, generally for protection or agricultural purposes. Geotextile are divided into short fiber nonwoven fabric and long fiber non woven geotextile . Geotextile can help hold the ground together, acting like synthetic roots while providing a stable base for new plant life to grow on. Geotextiles are used on ranches and farms, as well as eroding river systems, hillsides with homes and businesses, or any other place where soils need a little stabilization.

How to judge the quality of geotextile? Frist, We used to see the appearance of the short filament geotextile,especially experienced procurement and inspection personnel, they usually use eyes to see to some extent can judge of nonwoven fabric quality.The same quality standard short silks, the color is pure white means quality good. Second,about the compactness of the geotextile,we need to take a look at it and feel the compactness of the geotextile.Generally, the quality of the compactness is larger means the quality is better, and the density of geotextile obviously affects the quality of geotextile. Third method,laboratory tests: take a piece of short filament geotextile samples sent to the laboratory for testing is accurate and convenient method, laboratory test can clear short filament geotextile product breaking strength, elongation, CBR bursting strength index of geotextile related parameters and so on.Customers can compare their engineering construction parameters from these parameters, and it is obvious that the geotextiles are qualified or not.

In the past, civil engineering construction encountered that the soil is not suitable for construction, usually they will solve this problem by replacing the soil or by deep foundation construction method to avoid the construction of difficult soil. This makes the project cost higher and more difficult to constructed. Therefore, it is an urgent demand to find a material that can improve the construction conditions and the quality of the project. For a long time, due to the scarcity of land, the transformation of old urban infrastructure, the improvement of infrastructure quality and the demand of environmental governance, geosynthetics came into being. Now, we usually call it geotextile or non woven fabric. In the past 25 years, the area of application has rapidly expanded to civil, geotechnical, environmental and coastal areas and water conservancy projects in almost all areas of civil engineering, so it becomes an indispensable new geotextile material.
