There are many varieties of polymer chemical pulp materials, including epoxy resin, acrylamide (propionate), lignin, etc. Acrylamide and polyurethane are commonly used in chemical grouting of foundation. Acrylamide pulp is composed of main agent acrylamide and various admixtures. The viscosity of the slurry is close to water, and it has good groutability. After the slurry solidifies, the gel is impermeable, and has good durability and stability. This kind of slurry is widely used in seepage prevention grouting of fine rock cracks and medium fine sand layers and dynamic water leakage stoppage projects. This kind of pulp has certain toxicity and pollutes air and groundwater. The polyurethane slurry is mainly composed of polyisocyanate and polyether resin, and then mixed with various admixtures. After the slurry is poured into the formation, it reacts with water to form polyurethane foam, which can strengthen the foundation and prevent seepage and leakage. Polyurethane slurry can be divided into water-soluble and non-water-soluble. The water-soluble polyurethane can be miscible with water and react with water to form an aqueous gel; Water insoluble polyurethane can only be miscible with organic solvents. Polyurethane slurry has low viscosity, good groutability, high stone strength, safety and reliability, no pollution to the environment, simple operation and high economic benefits.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.Grand Gorica,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, 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, 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! It has good flexibility. The pipes can be coiled when they are produced, so that the number of joints in the pipe network can be reduced. It can be laid according to the terrain easily bypass obstacles, and is convenient for construction.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, 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 necessary to comprehensively consider the selection and configuration of grouting pipes, because there are many types of expansion joints, and correct selection is very important. Only in this way can the design of the piping system be safe, reasonable, reliable and economical.?Most of the grouting pipes on the market are meters in stock,BelarusPrice of advanced small conduit,BelarusAdvance small conduit support, and some construction sites have different requirements, so there are few in stock. In fact, they have different styles and different names. There are cross pair perforations and plum blossom holes. There are about holes in the whole pipe, which can be described as a hundred holes. One end of this pipe has plugs, sharp and round, depending on the customer&#;s requirements. The other end is welded with reinforcing bars from the pipe section to prevent the pipe section from tearing. This kind of pipe is called steel flower pipe. Steel flower pipe is generally used for high-speed maintenance grouting to protect mountains and prevent landslides. Holes are drilled on the steel flower pipe, which is more conducive to the penetration of cement mortar liquid into the rock and soil mass of the rock stratum and to the anchoring. In order to prevent the hole from being blocked by stones, sometimes the design requires reinforcement to protect the hole. After grouting the pipe orifice must be closed, so as not to let the grouting liquid flow out. The general classification of grouting pipe models can be divided into ordinary standard connection and pipe hoop connection according to their different connection methods. 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.analysis, 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, 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, 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.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.Two convex grooves are planned at the end of the bell end of the double seal clamp grouting pipe, and the convex grooves are equipped with sealing rings. During installation the spigot end of the product is stabbed into the bell end. The grouting pipe then kneads the two convex grooves together with a special hydraulic clamp, and the pipe at the kneaded part is shortened and deformed after being stressed. The outer pipe between the two convex grooves is deeply embedded into the inner pipe, a rubber sealing ring is deformed and pasted between two layers of pipes, which plays a double safety sealing effect.

When the grouting pipe is laid, it shall be kept flat and tight without wrinkling, so that the grouting pipe has effective tension. After laying, it shall be rolled again with a clean steel wheel roller. Most urban roads use glass fiber grouting pipes with self-adhesive. The diameter of the glass fiber grouting pipe is . ~ times of the maximum particle size of the asphalt concrete surface aggregate. The ultimate tensile strength should be greater than kN / m, so as to give play to the anti reflection crack performance of the glass fiber grouting pipe. It can also ensure the shear resistance and adhesive force of the adhesive layer of the glass fiber grouting pipe.Welcome to inquire,When the grouting pipe is laid, it shall be kept flat and tight without wrinkling, so that the grouting pipe has effective tension.

According to the type of reinforcement of the grouting pipe, the grouting pipe of parallel reinforcement (wire) bundle of the grouting pipe, one grouting pipe is generally used to anchor one reinforcement. For tendons and steel strands, a grouting pipe must anchor several steel bars or steel strands at the same time, which are often arranged in a ring or circle, or in a rectangle. Obviously, due to the different number and arrangement of prestressed reinforcement, the form and structure of grouting pipe will also be different. According to the principle of grouting pipe and transmitting pretension it can be divided into grouting pipe relying on bearing pressure, grouting pipe relying on friction and grouting pipe relying on adhesion.Belarus, Grouting pipe at tensioning end: the grouting pipe installed at the end of the grouting pipe reinforcement and capable of tensioning is also called grouting pipe grouting pipe. The so-called grouting pipe is a grouting pipe in post tensioning structure or component to maintain the tension of the grouting pipe reinforcement and transmit it to the mixed tension; Fixed end grouting pipe: a grouting pipe installed at the end of the grouting pipe reinforcement and usually buried in the concrete without tensioning. The standard of the grouting pipe used for the grouting pipe reinforcement is the national standard of the people&#;s Republic of China (GB / T -, which ensures that the products manufactured by our company conform to the product quality law of the people&#;s Republic of China and the standard law of the people&#;s Republic of China Grouting pipe is the only acoustic pipe specially used for ultrasonic testing in the market. The grouting pipe is made of cold and hard steel pipe after professional molding, and is connected by clamp pressure connection, screw connection, flange connection and other methods. It has a reliable anti-seepage effect during concrete pouring. Two convex grooves are planned at the end of the bell end of the high-strength double seal clamp type acoustic measuring pipe, and the convex grooves are equipped with sealing rings. When installing the device, the socket end of the product is stabbed into the bell end by cm, and then the two convex grooves are kneaded together with special hydraulic pliers. The pipe at the kneaded part is shortened and deformed after being stressed, and the outer pipe between the two convex grooves is deeply immersed into the inner pipe, and then the reliable connection of the product is completed; After being kneaded, the rubber sealing ring deforms and fits between the two layers of pipes, playing an excellent double safety sealing effect.Disposal method: the grouting pipe shall be shortened according to the specification. After the two pipes are connected by using the deformation of the grouting pipe, the kneading part of the joint is large at both ends and small in the center, 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.
