SoletracySuppoIt 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, it 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 permanently sealed in this way. Injecting grout into the embedded grouting pipe can seal construction joints, cold joints, pipe leakage and joints between the ground walls.
[0018] the fixed cutting device 2 is mainly composed of a cutting blade 6 and a pulley The cutting blade 6 and the pulley 7 are respectively connected to both sides of the cutting rotary device 5 through slots. The cutting blade is shown in Fig.
Sarah reed warlefield.If any crack is found, it shall be repaired in time, otherwise, when the joint is deformed and subjected to water pressure, the ability of the grouting pipe to resist external forces will be greatly reduced. When positioning the grouting pipe, it should be adjusted in time. When casting and fixing the grouting pipe, the deviation of the grouting pipe shall be prevented, so as not to shorten one side and affect the water stop effect. When pouring and tamping the concrete, it must be vibrated sufficiently to prevent the poor combination of the grouting pipe and the concrete from affecting the water stop effect. The grouting pipe joint must be well bonded. If the construction site conditions are available, the method of hot vulcanization connection can be used.?
2 the particle size of cement clay paste clay is generally very small (less than 0.005mm), the specific surface area is large, and it has colloidal chemical characteristics when encountering water. The characteristic of clay minerals is that their atoms are arranged in layers, and different arrangements form different clay minerals,Sarah reed warlefield25hollow grouting anchor bolt manufacturer, the most common being kaolinite, illite and montmorillonite.

The connection of detection pipes shall be smooth transition, the nozzle shall be more than 100mm higher than the pile top, and the nozzle height of each detection pipe shall be the same. The lower end of the pipe shall be closed, and the upper end shall be covered. There shall be no foreign matters in the pipe and no damage to the pipe body.
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, medical industry, fitness equipment and other fields. As its practicality is further recognized, its scope of application is becoming wider and wider. Some people in the industry asked: the application range of grouting pipe is becoming wider and wider. Does it have an impact on the original telescopic spring? In my personal opinion, 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, so its design has certain limitations convenient and labor-saving. Some units do not know it, However,Sarah reed warlefieldTunnel small conduit, 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, we hope that some industries, such as machinery manufacturing, 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, complete set. No special installation equipment is required grouting is not allowed. Product advantages: Simple installation, and the cut-off length can be prepared on the construction site according to the actual requirements of the joint (it is recommended that the longest grouting outlet length should not exceed 6m). The grouting time can be arbitrarily selected.

Inner diameter of repetitive grouting pipe: 8mm; Outer diameter: 20mm Inner diameter tolerance: ± 0.3mm; Length of each roll: 90m.
This seems to test what I learned in junior high school. The formula for calculating the weight per linear meter of a cylinder I learned at that time is now used. However, it may be more troublesome to calculate according to that formula. It is necessary to calculate the weight per linear meter of the outer cylinder with the formula, and then subtract the weight per linear meter of the inner space. I have a headache when I think about it! With less gossip, I'd better provide you with a method to correctly calculate the weight of the grouting pipe per linear meter!
Product specification of disposable grouting pipe: outer diameter: 12mm; Inner diameter: 8mm; Inner diameter tolerance: ± 0.3mm; Packing quantity: each roll of grouting pipe is 120m long.
Classified according to the movement mode of grout in the stratum Filling grouting: filling large cracks and caves with grout is called filling grouting.
build.[0014] Middle label: 1 refers to flange 2 refers to fixed cutting device, 3 refers to tightening blade device, 4 refers to tightening blade nut, 5 refers to cutting rotating device, 6 refers to cutting blade, curing water and garbage from falling in. When necessary, a sump shall be set near the post cast strip of the base plate in combination with the design of the basement plane drainage system to facilitate the final cleaning before the grouting pipe is cast. When advance water stop is not used, a sump shall be set, which can be set in the basement according to the above method, or set outdoors as a temporary facility. Usually, we use the waterproof scheme between the grouting pipe and the water surface or before, and there are many methods for the grouting pipe to stop water in advance. It should be noted that the design unit should participate in the review of the construction organization design of the basement, so as to determine a complete implementation scheme of advanced water stop before the excavation of the foundation pit and the pouring of the cushion. Otherwise, the design modification requirements will be put forward only when problems are found in advance water stop during construction, which will affect the integrity and rationality of the whole water stop scheme.
How to connect the grouting water stop needle and the grouting pipe after the grouting water stop needle and the grouting pipe are connected, a set of grouting system will be formed. As long as the small part of the grouting needle is inserted into the joint of the lotus petal grouting pipe, a closed and self-locking grouting system will be formed.
Sarah reed warlefield.The so-called direct grouting method refers to the method of directly placing the grouting pipe into the soil by vibrating or drilling. According to the different forms of grouting pipes, the direct grouting method can be divided into the grouting pipe grouting method, the flower pipe grouting method, the drill pipe grouting method, and the stop plug grouting method.Grouting pipe grouting method refers to the method of grouting directly through the nozzle at the lower part of the grouting pipe; The flower tube grouting method is a method of grouting through a grouting tube (flower tube) with multiple grouting holes on the side wall; The drill pipe grouting method refers to the method of grouting directly through the drill pipe for drilling.
After the sodium hydroxide solution is poured in, the calcium chloride solution is poured in, which is called the two liquid method. Alkali solution method has the advantages of simple construction equipment, low reinforcement cost, and elimination of collapsibility of loess.
