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,Scottsdale42 small catheter, the construction unit shall apply for changing the detection method The low strain reflection wave method or high strain strain strain measurement method shall be used and signed by the supervisor&#;s representative and the person in charge of quality supervision before implementation; In case of pipe blockage of a bridge for many times, core drilling inspection shall be carried out in due time. Other uses of grouting pipe introduction the grouting pipe of pile foundation refers to the steel pipe that needs to be embedded when testing the quality of pile foundation. Generally, it is bound in the reinforcement cage and lowered into the hole together with the reinforcement cage before pouring concrete! There are many reasons for the grouting pipe to gamble on the pipe, most of which are due to the leakage of slurry caused by the pipe joint not being welded well during processing, and also due to the pipe mouth not being closed well and falling debris, the pipe is blocked! To put it bluntly, the pipe is blocked by sundries! The role of the grouting pipe is to inject clean water into the grouting pipe and put the transducer into the grouting pipe for testing when the integrity of the pile foundation is tested by ultrasonic wave. If the grouting pipe is blocked, the transducer can not be put in, or can not be placed at the bottom of the pile, so it is impossible to comprehensively test the whole pile and judge the quality of the pile foundation!The grouting pipe at the tensioning end has good anchoring energy and self anchoring energy. Grouting pipe is generally used for tensioning. The grouting pipe at the tensioning end is composed of four parts: clip, anchor plate, anchor base plate and spiral reinforcement. The clip is the key part of the anchoring system. It is two-piece and made of high-quality alloy steel.Scottsdale,If there is no leakage, tunnel and basement. If there is water leakage, grout can be injected into the pipe body to fill and seal. If there is no leakage, grouting can be omitted. Grouting pipe is a kind of embedded grouting pipe system, which is used for permanent sealing of construction joints, cold joints, pipe seepage joints and gaps between ground walls in concrete. It is very suitable to install grouting pipes between the joints of new and old concrete. When water penetrates into the joint, the joint can be sealed by injecting slurry into the PVC port set on the surface. The proper grouting time can be selected after the concrete curing. Leakage joints can also be made into durable seals by this method.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.Siguiri,The grouting pipe at the tensioning end has good anchoring energy and self anchoring energy. Grouting pipe is generally used for tensioning. The grouting pipe at the tensioning end is composed of four parts: clip, anchor plate anchor base plate and spiral reinforcement. The clip is the key part of the anchoring system. It is two-piece and made of high-quality alloy steel.The grouting pipe without shaft roll packaging is tapped and paid off from the inner ring in the vertical state, and the drawn out pipe is spring shaped and automatically straightened. Takeout direction: the spiral direction of the spring shape after takeout is consistent with the twisting direction of, otherwise fried dough twist or disorder will occur. Welding is strictly prohibited during use, because the strength of the welding point is much lower than that of the steel itself, and it is easy to cause broken wires at the welding point during tensioning. When the grouting pipe adopts circular reinforcement arrangement, its bending radius shall not be less than times of the diameter.The existence of grouting pipe mesh restricts the lateral movement of soil. The lateral sliding deformation of the soil is limited by friction and interlocking engagement between the grouting pipe and the sand particles and the passive resistance of the sand particles to the grouting pipe, forming a good interlocking effect, so that the soil has better overall shear strength and bending stiffness.

The grouting pipe is used to pad the bottom of the horseshoe, change the cooperation specification of the mold, and adjust the cooperation space between the lower tire and the horseshoe.Consolidation Prevent landslide Reduce ground subsidence Improve foundation bearing capacity Backfill Reinforcement materials: cement slurry, chemical slurry, mixed slurry object: rock grouting, gravel grouting clay grouting, coal body grouting coal and rock mass grouting : anti-seepage grouting, reinforcement grouting,Scottsdale32lead small conduit, foundation underpinning grouting, water blocking reinforcement grouting, sealing filling grouting mechanism: filling grouting, splitting and vein grouting, bedrock crack grouting, seepage grouting Interface grouting, concrete crack grouting, compaction grouting pressure: static pressure grouting, high-pressure jet grouting ceramic technology; It is divided into high-pressure grouting and ordinary grouting injection grouting.It is proved by experiments that the bearing capacity of the same bored pile with and without grouting pipe is separated by %. That is why more and more bored piles and grouting pipe grouting are used more and more widely in ChinaMarketing Department, 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.It is proved by experiments that the bearing capacity of the same bored pile with and without grouting pipe is separated by %. That is why more and more bored piles and grouting pipe grouting are used more and more widely in China It is safe and does not need to be welded on site.

The commonly used standard for grouting pipe is the inner diameter of -mm. The wall thickness of the pipe has little effect on the sound transmission,ScottsdaleSmall catheter, so there is generally no need to restrict the thickness of the pipe wall. However, from the perspective of saving steel consumption, it is OK if the pipe wall can bear the lateral pressure of new concrete, not necessarily the thicker the better.Where can I find it?The longitudinal overlapping width of grouting pipe and grouting pipe shall not be less than cm, and the transverse overlapping width shall not be less than cm. The former shall be placed on the latter according to the asphalt paving direction. After laying the glass fiber grouting pipe fix the glass fiber grouting pipe with high-quality cement nails and fixed iron sheets with a size of mm, mm and a thickness of .mm. The fixed spacing can be determined according to the actual construction situation.Advantages of disposable grouting pipe: simple installation, complete set. No special installation equipment is required, 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 m), and the grouting time can be arbitrarily selected.When the grouting pipe is installed, the axis deviation shall be ≤ cm and the bearing capacity of the support joint shall meet the design requirements. When connecting the grouting pipes, bolts must be installed symmetrically and tightened in sequence. Meanwhile, in order to prevent excessive deflection of the grouting pipes when axial force is applied, the deflection must be corrected to the horizontal before axial force is applied.Scottsdale,Disposal method: the grouting pipe shall be shortened according to the specification.In the construction of some grouting pipes, after the completion of the construction of the project, because some construction personnel did not take protective measures after the completion of the grouting pipes, the project was damaged due to some external factors. In order to help users effectively improve the construction quality of the grouting pipes, the following article introduces the protective measures that should be taken after the completion of the construction of the waterproof layer of the grouting pipes. For various engineering designs, waterproof and water stop shall be carried out throughout the whole process of grouting pipe until the backfilling soil is completed.Answer: Yes, the elastic extension speed of the grouting pipe can be defined within a certain range in the design, but for a grouting pipe that has been designed, its elastic extension speed is certain.
