San JosePipe s(the density of steel pipe is 85kg/dm calculation formula: w = 0.02466 (D-S) s where: W - theoretical weight of steel pipe per meter, mm; S - nominal wall thickness of steel pipe, mm.
Advantages of disposable grouting pipe: simple installation, complete set. No special installation equipment is required,GuihuSupport small conduit, and the cut-off length can be prepared on the construction site according to the actual requirements of the joint (the longest grouting pipe length is recommended not to exceed 6m), and the grouting time can be arbitrarily selected.
Guihu.In the engineering practice, some construction units directly pave the glass fiber grouting pipe after spraying the sticky layer oil, and the roller rolls after it. The effect is good, and the glass fiber grouting pipe is not easy to wave. Strictly control the entry and exit of vehicles transporting the mixture, and forbid vehicles to swerve, brake and dump the leftover mixture on the grouting pipe layer to prevent damage to the glass fiber grouting pipe; The back glue of glass fiber grouting pipe is easily soluble in water, and construction shall not be carried out in rainy days or wet roads; Glass fiber grouting pipe is made of grouting pipe, which is easy to irritate human skin. Construction personnel must wear protective gloves; When the grouting pipe is laid, the temperature of the road surface is required to be between 560. Therefore, the relative displacement trend or relative displacement will occur between the narrow two, which will then generate friction. This friction is generally called &surface friction&.
The setting and curing reaction of cement water glass slurry includes cement hydration reaction and the reaction of Ca (OH) 2, the product of cement hydration reaction, with water glass, that is, after cement and water are mixed into cement slurry, Ca (OH) 2 with strong activity is produced due to hydrolysis and hydration; Water glass interacts with Ca (OH) 2 to form a gel with certain strength - calcium silicate hydrate. The reaction is as follows [2].
. The installation will not affect the characteristics of the building grouting pipe; The installation or grouting process will not harm the concrete; Permanent sealing can be ensured after grouting; If there is no leakage, grouting is not allowed. Product advantages: Simple installation, complete set. No special installation equipment is required,

When lifting and demoulding components, the concrete strength must meet the design requirements. When there are no special requirements in the design, the non prestressed members shall not be less than 50% of the designed standard value of concrete cube compressive strength, and the prestressed members shall not be less than 75% of the designed standard value of concrete cube compressive strength.
The Xiaobian of prestressed machines and tools reminds us that there are many forms of grouting pipes, which can be distinguished from different angles including the following. According to the type of reinforcement of the grouting pipe, it can be divided into the grouting pipe of thick reinforcement of the grouting pipe, the grouting pipe of parallel reinforcement (wire) bundle of the grouting pipe, and the grouting pipe of steel strand bundle of the grouting pipe. For thick reinforcement, a grouting pipe must anchor several steel bars or steel strands at the same time, which are often arranged in a ring or circle, or in a rectangle. Obviously, due to the different number and arrangement of prestressed reinforcement, the form and structure of grouting pipe will also be different. According to the principle of grouting pipe and transmitting pretension, it can be divided into grouting pipe relying on bearing pressure, grouting pipe relying on friction and grouting pipe relying on adhesion.
Cut and cut the spring skeleton grouting pipe according to the components. The cutting surface must be flat and free of burrs. The length of its flat section must be ≥ the connecting reinforcement measures. During the bending process of the grouting pipe, it is not allowed to use a small one. The inner diameter of the grouting pipe is compressed and cracked. The alignment between M and FL is 45-56
Good quality.1 water glass grouting material water glass slurry is made of water glass as the main agent, and gelling agent is added to make it react chemically and generate a large amount of silicon gel to set and harden. Water glass paste has wide sources, low cost, small toxic and side effects of main agent, no environmental pollution, low viscosity and good injectability.
Professional sales, absolute sound detection tube price advantage, providing the most cost-effective products.
The concrete shall be evenly distributed, and the vibration shall be &fast inserting and slow pulling& and slightly pumping up and down to make the concrete vibrate evenly. The vibration shall be carried out in sequence to avoid over vibration and missing vibration until the concrete surface is horizontal, no significant subsidence, no bubbles and no mortar on the surface. During vibration, the vibrating handle shall not touch the side formwork, grouting pipe, pipeline, embedded parts, etc.
Provide considerate service, solve customer problems, and realize one-stop procurement.
new product. The grouting pipe has good flexibility. When the pipe is produced it can be coiled, so that the number of joints in the pipe network can be reduced. It can be laid according to the terrain, easily bypass obstacles, and is convenient for construction.
Answer: according to the length and diameter the weight of common grouting pipe is 0.1 ~ 0.3KG, and the weight can reach several kilograms.Application scope and development space of grouting pipe as a new term, grouting pipe has gradually appeared in some online newspapers and periodicals, and its practical scope has also developed from the support of some basic automobile boot and engine cover to the machinery manufacturing industry, used for the support of equipment accessories, vibration reduction of equipment, support of tool box cover, it will not impact the original spring. Of course, it will have a certain impact, because most of the grouting pipes are innovations in the product design of some enterprises. For example, the rear box of a tricycle was originally supported by an iron bar (which is still useful). Now, the grouting pipe is very light, convenient and labor-saving. Some units do not know it, so its design has certain limitations, However, enterprises must be innovative in order to be ahead of their peers. We have been making grouting pipes for many years. Experience tells us that many manufacturers are now trying our grouting pipes, and they have been officially used, with obvious effects. However, some enterprises do not know what the grouting pipes are,GuihuSelf drilling hollow anchor manufacturer, let alone their s so they will be in a passive position. Therefore, such as machinery manufacturing we hope that some industries, automobile and motorcycle transportation equipment, box manufacturing such as tool boxes, medical treatment, fitness, kitchen cabinets, etc, If you need to know the and use of the grouting pipe, please feel free to consult me, and I will give you advice
The grouting pipe of the spring reinforcement framework shall be bound with the bamboo frame of the reinforcement framework according to the construction rigidity of the component. After being bound into a bundle, it shall be stacked at the specified position and lifted to the abutment cross. During the reinforcement binding process, the quality and wall shall be strictly controlled according to the ship support, and the finished product shall be well protected. The injection pipe shall be placed on the top, and the embedded grouting symbol shall be buried on the formwork for positioning. The inverted formwork shall be used to install stairs and component side formworks to increase the turnover rate of the formwork as much as possible. According to the design size, the formwork shall be cut with plate shears, edge folding machines, profile training machines, etc. the blanking standards shall be used for rebar concealment and cross slab. The unqualified ones shall be rectified until they meet the construction technology. Concrete pouring Before concrete mixing, the moisture content of sand and stone shall be measured and the construction mix proportion shall be adjusted according to the test results.
Guihu.Weight per linear meter = (outer diameter - wall thickness) * wall thickness * 0.0246615 where the outer diameter refers to the outer circumferential diameter of the grouting pipe; The wall thickness is the difference between the outer diameter and the inner diameter; The above content is the calculation method of the specification and weight of the grouting pipe introduced. I hope it will be helpful to you in the future.
