The arrangement of the strain gauge shall be installed before the prestressing force is applied and the bracket shall be fully cooled when the initial reading is measured; If the prestress has been applied, it must be noted in the report that the supporting axial force data reflects the change of the stress of the grouting pipe after the prestress is applied.Answer: Yes, it can be protected. The piston rod can be protected by adding plastic hoses or bellows within the travel range.Fort Wayne,The chemical grouting method usually uses a pump to inject grout into the soil through a grouting pipe. The bottom of the horseshoe of the grouting pipe is too low. After the horseshoe is seated in the mold, the space between the outer mold and the horseshoe surface is greater than the thickness of the pipe wall.Zory,The glass fiber grouting pipe is a rigid product made of high-strength alkali free peeling fiber, which is made into a mesh base material through an internationally advanced fine knitting process and is surface coated. Unidirectional tensile plastic grouting pipe is a grouting pipe made of high-density polyethylene (HDPE) as raw material, plasticized and extruded plate, punched, heated and stretched, extruded and pressed, and then punched with regular hole network, and then stretched longitudinally. In this process, the polymer is in a directional linear state and forms an oblong reticular integral structure with uniform distribution and high node strength. The tensile strength and rigidity of the grouting pipe are fully improved through the reorientation of the originally scattered chain molecules into a linear state by stretching.It is laid in the soil, and through the bite and interlock between the grouting pipe mesh and the soil, it forms an efficient stress transmission mechanism, so that the local load can quickly and effectively spread to the large area of soil, so as to reduce the local failure stress and improve the service life of the project. The convex joint steel plastic grouting pipe is an upgraded product of the ordinary steel plastic grouting pipe, which changes the shortcomings of the ordinary grouting pipe, the easy cracking of the welding point, the difficulty of construction, and the reduction of the role of side displacement prevention. Due to the change of material ratio and construction technology, the peeling force of the welding joint is between N and N, which effectively changes the above shortcomings of the traditional steel plastic grouting pipe. Because of the protruding joints at the welding position, it is called convex joint steel plastic grouting pipe, and its academic name is node reinforced steel plastic grouting pipe. The steel plastic grouting pipe is made of high-strength steel wire (or other fibers) through special treatment,Fort WayneGrouting pipe grouting, polyethylene (PE) and other additives and is extruded to form a composite high-strength tensile strip. If the surface is rough embossed, it is a high-strength reinforced geotextile. This single belt is woven or sandwiched at a certain distance longitudinally and horizontally, and the drawn out pipe forms a spring shape and stretches automatically. Takeout direction: the spiral direction of the spring shape after takeout is consistent with the twisting direction of, 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.

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. The fast cutting device in the hole of the underground grouting pipe according to claim , wherein the outer diameter of the cutting rotating device is mm smaller than the inner diameter of the grouting pipe. After the two pipes are connected by using the deformation of the grouting pipe,Fort WayneGrouting small conduit and advance anchor rod, the kneading part of the joint is large at both ends and small in the center,Fort WayneAdvance support small conduit, so that the joint is stuck at one time, avoiding the possibility of loose union. The grouting pipe has proper, stable and excellent s in terms of tensile pull-out and torque resistance, and the protrusion is circular arc with small protrusion, which is useful to avoid collision with conduits, vibrators etc.safety requirements , 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.Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more. It is safe and does not need to be welded on site.

Advantages: It is connected with special hydraulic tongs, does not require preparations outside the construction site, does not require any equipment, is convenient and fast ( times faster than the traditional welding method), is simple to fix the grouting pipe to the reinforcement cage, and is not affected by the bad weather.Promotion Classification of grouting pipe grouting pipe the grouting pipe is a plane mesh material of grouting pipe with certain flexibility. The main raw material is polyethylene grouting pipe. It is extruded into thin sheets by a grouting pipe extruder, and then punched with regular holes. Then it is made by directional stretching under the control of heating. It can be divided into unidirectional grouting pipe and bidirectional grouting pipe according to the different stretching modes when it is manufactured. The grouting water ratio of grouting construction is .: ~ .: (i.e. the weight ratio of water and cement), and the principle of 'dilute first and then dense' is adopted. Por early strength Portland cement is used as the cement. Before mixing the cement slurry, the quality of the cement shall be checked. If it is found that the cement is hardened and deteriorated or fails the test, it shall be discarded to prevent the quality of pile end grouting from being affected by the deteriorated cement. The grouting time should be - days and - days after the completion of single bearing platform pile construction.Disposal method: the grouting pipe shall be shortened according to the specification.Fort Wayne, The length can be matched according to the construction requirements, without loss. The saddle shaped curved surface on the horseshoe surface of the grouting pipe and the upper and outer molds are not well fitted
