Delamondville5
SoletracySuppoIt can be widely used for one-time multiple grouting pastes.
Inner diameter: 8mm; Outer diameter: 24mm; Inner diameter tolerance: ± 0.3mm; Length of each roll: 50m.
Delamondville.Answer: according to the length and diameter, the weight of common grouting pipe is 0.1 ~ 0.3KG, 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, medical industry, fitness equipment and other fields. As its practicality is further recognized,DelamondvilleCustomized leading small catheter, 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, let alone their s, so they will be in a passive position. Therefore, 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
According to the sequence of sectional construction along the stratum depth, grouting can be divided into sectional downward, sectional upward and one-time full depth grouting. The segmented downward type starts from the ground, drills a section of holes from top to bottom, and injects a section of grout. After each section of grouting, the drilling and grouting continue to be continued downward, so as to alternately reach the designed final grouting depth, and then carries out re grouting from bottom to top; The segmented upward type is that the grouting hole is drilled to the final grouting depth at one time, and the grouting is segmented from bottom to top using a grout stopper; The method of one-time full depth grouting is to drill the grouting hole to the final grouting depth at one time, and then conduct one-time grouting to the full depth.
. Non woven filter cloth layer outside the framework. Only water and grout are allowed to pass through, and other materials such as cement slurry in concrete are blocked outside the grouting pipe to ensure smooth use of the whole section of the grouting pipe.
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, carefully check the embedded reinforcement in the groove before the joint is lowered. If cracks or breaks are found, the position is improper or the gap is too large, remedial measures must be taken.
[Patent Description] fast cutting device in the hole of underground grouting pipe [technical field] [0001] the utility model relates to a device for cutting grouting pipe in a coal mine, in particular to a fast cutting device in the hole of underground grouting pipe.
The foundation pit excavation shall strictly follow the principle of &layered excavation&. The support erection shall be closely coordinated with the earthwork excavation. During the excavation, the earthwork near the grouting pipe shall be excavated by the central trenching method to prevent the machinery from colliding with the support; The earthwork near the slope protection pile shall be excavated manually with small machines and tools. It is forbidden to collide with the grouting pipe and bored pile by mechanical excavation. After the earthwork is excavated to the design elevation, the grouting pipe shall be erected and prestressed in time to reduce the exposure time without support.
The installation will not affect the characteristics of the building grouting pipe itself; 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; Ccll-y series grouting pipe: grouting once, not reusable ccll-d series grouting pipe: multiple times of grouting, grouting is not limited by time.It is applicable to waterproof joints of subway, tunnel and basement. If there is water leakage, grout can be injected into the pipe body to fill and seal. It is very suitable to install grouting pipes between the joints of new and old concrete. Various materials such as cement slurry, polymer slurry and polyurethane chemical slurry can be injected. When water penetrates into the joint, the joint can be sealed by injecting slurry into the PVC port or spring skeleton port set on the surface. The proper grouting time can be selected after the concrete curing. Leakage joints can also be permanently sealed in this way.
query. The fast cutting device in the hole of the underground grouting pipe according to claim 2, wherein the cutting rotating device rotates the cutting blade and pulley through a socket wrench to cut the casing wall, the transmitting and receiving probes shall rise and fall synchronously at the same elevation or maintain a fixed elevation difference.
● features: the grouting pipe is divided into disposable grouting pipe (ccll-y grouting pipe, qdm-it grouting pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe)
quality.(outer diameter - wall thickness) what is actually obtained is the average value of the inner and outer diameters of the circumference. If this value is multiplied by the circumference ratio (π = 141592, the circumference will be obtained. If the circumference is multiplied by the wall thickness, the area of a section will be obtained. If the area of this section is multiplied by 1 meter (1000mm), the adjusted volume will be obtained. If the adjusted volume is multiplied by the density of 85, the weight of one meter length will be obtained.
General treatment method: first, yze what causes the pipe blockage. For the pipe blockage of hard objects, you can poke with steel bars according to the depth, or bind a slightly thicker steel bar with steel wire rope. For the pipe blockage of soft objects, you can use the air compressor pipe to open the air compressor for blowing. Be sure to note that the water in the pipe may rush up like a fountain to pour water all over you! If it is slurry leakage and pipe plugging, there is no way to open it. We can only communicate with the testing personnel to change a testing method, such as low strain and core drilling method! Other uses of the grouting pipe: in addition to being used as a detection channel and replacing part of the reinforcement section, the grouting pipe can also be used as a pipe for grouting at the bottom of the pile. Experiments have proved that the bearing capacity of the cast-in-place pile treated with the grouting at the bottom of the pile can be greatly improved. At the same time, the grouting pipe can also be used as a channel for the defect washing and grouting treatment of the accident pile. At this time, it is necessary to take measures to punch through the pipe at the defective part to be grouted. Grouting pipe is specialized in the production of grouting pipe (ultrasonic detection pipe) for bridge pile foundation inspection. The product conforms to the industrial standard steel thin-walled grouting pipe for concrete cast-in-place pile and its use requirements (JT / T 705-200,DelamondvilleSelf drilling hollow anchor manufacturer, which was tried out by the Ministry of communications of the people's Republic of China on April 1, 200 It can not only meet the requirements of the standard,DelamondvilleLeading small conduit42, but also greatly improve each index and obtain the inspection report of Hebei Road and Bridge Inspection Center.
The grouting can be repeated many times.
Delamondville.However, its setting time is not stable enough, the controllable range is small, the strength of the condensate is low, and the stability is poor. It is mainly used in temporary or semi permanent projects [4].
