2024-04-20 02:39:42The grouting pipe is padded with the front lip of the horseshoe, lateral and angular directions on the pipeline. From the perspective of its performance, the internal pressure grouting pipe can be displaced in three directions, but because it is limited by casing and other accessories, it can often only be displaced in the axial direction. Therefore, the user needs to indicate the displacement in several directions when selecting and ordering, so as to select correctly. The working principle of the grouting pipe is to use its own elastic deformation to compensate the axial, angular, lateral and combined displacement of the pipe due to thermal deformation mechanical deformation and various mechanical vibrations. The compensation has the s of sealing, pressure resistance, temperature resistance, corrosion resistance, impact resistance, vibration reduction and noise reduction, which can reduce the deformation of the pipe and improve the service life of the pipe.Sandino ,During high-pressure grouting, about cm to the left and right. The straight-line distance between the two water stop needles is about cm. If the crack is too large, it can be directly drilled vertically to the crack.The grouting pipe shall be cut with a toothless saw (grinding wheel clamp). Cutting by electric or gas welding is easy to damage the surrounding surface and cause local heating at the end, which significantly reduces its performance. During the use of the grouting pipe, it is forbidden to take any form of heating deformation measures to avoid reducing the mechanical properties of the grouting pipe.San Miguel de Salcedo,Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more. The grouting pipe is padded with the front lip of the horseshoe, and the height of the saddle shaped curved surface is changed to make the pipe wall crawl and slide along the accurate saddle shaped curved surface.How to deal with the joint if the grouting pipe is installed in sections? If the grouting pipe is installed in sections, and can be installed after the two-phase adjacent joints are aligned. After all beams are welded, anchor them according to the above steps. Install the formwork at the beam end. The formwork shall be made according to the overall dimensions of Hainan grouting pipe device and the notch of the reserved slot. The formwork shall be made quite tight to prevent mortar from flowing into the displacement control box or into the beam end gap.After checking that the installed formwork is tight and seamless, clean the reserved groove, and the grouting pipe device in Hainan shall be kept clean when pouring concrete.
A short section of screw end rod is welded on both ends of a single prestressed thick steel bar, and the nut and backing plate are sleeved to form the simplest grouting pipe. The pretension force is transmitted to the nut through the bearing force on the threaded slope of the screw end rod, and then to the concrete components around the reserved hole crossing through the base plate.Lets take a look at the prestressed machines and tools. The small editor of prestressed machines and tools reminds everyone that the screw end rod is made of cold drawn or heat-treated reinforcement, and the thread is fine teeth. The welding between the end rod and the prestressed reinforcement should be carried out before the cold drawing of the prestressed reinforcement. This grouting pipe can be used at the tensioning end and the fixed end. A general jack is used for tensioning, and the jack pull rod (with internal thread at the end) is tightened on the thread of the screw end rod for tensioning. After tensioning, tighten the nut and anchor the rebar. The advantages of this grouting pipe are relatively simple, and when the jack returns oil after the grouting pipe the prestressed reinforcement basically does not slide. If necessary, facilitate re tensioning. The disadvantage is that the accuracy of the length of prestressed reinforcement is high, and it cannot be too long or too short, otherwise the thread length is not enough. Post grouting: after the shaft, tunnel, basement and other structures are dug, the grouting method is used to control water damage and strengthen the stratum,Sandino 50lacrimal duct, which is called post grouting.How heavy is a grouting pipe?investment, Glass fiber grouting pipe is a semi-rigid product made of glass fiber as raw material, high-strength alkali free glass fiber through a certain warp knitting process, and fiber filament coated on both sides. The overhead type is a special rack installed at the bottom of the driving head and connected with the wellhead tensioning equipment. The grouting pipe is a patented product. Compared with similar products in the market, it has higher tensile resistance and better sealing performance.
Can the stretching speed of grouting pipe be defined?Analysis project,How to deal with the joint if the grouting pipe is installed in sections? If the grouting pipe is installed in sections, the joints must be welded. The welded joints of the section steel have been prepared in the manufacturing plant, and can be installed after the two-phase adjacent joints are aligned. After all beams are welded, anchor them according to the above steps. Install the formwork at the beam end. The formwork shall be made according to the overall dimensions of Hainan grouting pipe device and the notch of the reserved slot. The formwork shall be made quite tight to prevent mortar from flowing into the displacement control box or into the beam end gap.After checking that the installed formwork is tight and seamless, clean the reserved groove, then pour concrete and vibrate it tightly. The concrete shall have at least the same strength as the structural concrete at this place, and the grouting pipe device in Hainan shall be kept clean when pouring concrete.Inner diameter of repetitive grouting pipe: mm; Outer diameter: mm Inner diameter tolerance: ± .mm; Length of each roll: m.There are many forms of grouting pipes that can be improved and applied. Although the engineering pipeline system is very complex, any complex pipe system can be divided into several relatively simple individual pipe sections through the setting of fixed pipe racks. When selecting the corrugated grouting pipe, the deformation compensation of the pipe system can be determined according to these relatively simple pipe sections, so as to select the grouting pipe.Sandino , The small editor of the grouting pipe reminds everyone that there should be no rust water and other impurities when using the prestressed machinery. The working clip can be used after removing the foam in the packing box, and the grouting pipe should be properly kept. However, when the prestressed tendon is long and the grouting pipe needs to be tensioned repeatedly, it is suggested that a small amount of lubricant (e.g. anchor pulling spirit) be applied to the tapered hole of the anchor plate by the prestressed machine, which is not only conducive to the follow-up and anchor pulling of the working clip, but also conducive to the multiple grouting of the grouting pipe; Apply lubricant on the outer surface of the tool clip and the inner and outer surfaces of the taper hole of the anchor plate before use,Sandino 50lead small conduit, and regularly remove the debris on the clip surface to make the anchor flexible. However, when the clip is cracked or the tooth surface is damaged, it needs to be replaced and can not be used again.When the pipe cannot be connected due to serious blockage, the following treatment principles must be followed: when it is the first pile of a certain bridge, core drilling detection must be carried out; when it is not the first pile of a certain bridge, core drilling inspection shall be carried out in due time. Common problems and answers of grouting pipe what is the pressure inside the grouting pipe? Action mechanism of grouting pipe: the grouting pipe is a flexible material. Under the action of soil load, it is a mechanism of dispersing the force on each hole belt and forming a resultant force.
