SoletracySuppoThe flexibility of the product is very high, and it is easy to place at the corners without cutting and connecting.
Type of grouting pipe: disposable grouting pipe: grouting once, non reusable.
Saint Jerome .The use of grouting pipes has become indispensable in modern building construction, because China's ancient buildings are very technical in construction. In China, before 1949 and in the early 1950s, grouting pipes made of bamboo and wood were used in the construction of buildings. After the mounting bracket is welded on the surface of the grouting pipe, push the strain gauge in a stable and free state without bending and twisting; The mounting bracket and strain gauge shall be installed parallel to the support axis; When tightening the screw,Saint Jerome Leading small catheter, pay attention to reasonably controlling the frequency of the strain gauge; The installation position of the strain gauge shall be selected at the position suitable for protection as far as possible.
Chemical grouting: the grouting material is mainly chemical liquid.
. Permanent sealing can be ensured after grouting. If there is no leakage, grouting can be omitted.
Ceramic process 1: make and process gypsum molds according to the requirements of a certain place.
Classified according to the movement mode of grout in the stratum Filling grouting: filling large cracks and caves with grout is called filling grouting.
In addition, the water corrosion test results of the grouting material simulating the fresh water erosion environment show that the strength of the stone body of the grouting material does not lose under the condition of water corrosion for 180 days, while the strength loss of the cement water glass grouting material reaches 50%, which shows that the water corrosion resistance durability of the water glass industrial waste two liquid grouting material is better than that of the cement water glass two liquid grouting material [7].
The quality of the steel upsetting head of the grouting pipe is not directly related to its own quality, but the excessive strength will be harmful to the quality of the upsetting head. Therefore, when you choose the upsetting head anchor, you should explain it in detail to the manufacturer in the order. The grouting pipe shall be cut with a toothless saw (grinding wheel clamp). Cutting by electric or gas welding is easy to damage the surrounding surface and cause local heating at the end, which significantly reduces its performance. During the use of the grouting pipe, it is forbidden to take any form of heating deformation measures to avoid reducing the mechanical properties of the grouting pipe.
Clay grouting: the slurry material is mainly clay, including clay cement slurry.
Scheme customization.If there is no leakage, grouting can be avoided; Common specifications ccll-y series grouting pipe: grouting once, non reusable ccll-d series grouting pipe: multiple grouting, grouting is not limited by time.It is applicable to waterproof joints of subway tunnel and basement. If there is water leakage,Saint Jerome Grouting small conduit and advance anchor rod, 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,Saint Jerome 50lacrimal duct, 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.
[0022] when the utility model is in use, the flange plate is used to fix the utility model and the flange plate of the underground grouting pipe, the bolt is rotated with a tool, the cutting blade is adjusted to a certain position by the screw on the bolt and then fixed, and then the screw cap of the blade is rotated and tightened to make the cutting blade and the pulley contact the inner surface of the grouting pipe with a certain contact force, that is, neither loose nor tight. The cutting blade and the pulley are directly inserted into the concave groove of the rotating device through the slot and the cutting rotating device is fastened and rotated by a wrench or a tooth wrench, and the pulley and the blade are driven to rotate by the rotation of the bolt, thereby rotating the casing. The pulley is located on the other side of the rotating device, corresponding to the blade. It is mainly used to reduce the friction between the rotating device and the casing wall, and fix the position of the blade in the casing, so as to prevent the blade on one side from shifting during cutting, failing to achieve the cutting purpose, or even damaging the blade. The fastening bolt is rotated by a wrench or tooth wrench, so as to drive the pulley and blade to rotate. The cutting rotating device cuts the casing. When the casing is cut to a certain depth, ordinary portland cement or slag Portland cement; For the concrete mixed with retarded admixture or with impermeability requirements, it shall not be less than 14 degrees. The cured concrete shall be covered with plastic cloth, and all exposed surfaces shall be tightly covered, and condensed water shall be kept in the plastic cloth.
Interpretation and observation.It is required to ensure that at least one embedded reinforcement is firmly welded with the anchor ring of maolehan grouting pipe within every meter along the joint direction. The quality of XF type grouting pipe should be carefully checked. If deformation or inconsistent spacing between two steel beams is found, it should be repaired. If necessary, the steel beam spacing of maolehan grouting pipe shall also be adjusted according to the ambient temperature during installation. XF type grouting pipe device shall be slowly put into the groove, so that the center line of the joint coincides with the center line of the actual reserved joint, and the deviation shall not exceed 10mm. Meanwhile, the inner edge of the steel side beam shall be kept vertical. After the XF grouting pipe is in place, the top surface of the steel beam of the grouting pipe shall be adjusted according to the longitudinal, transverse slope and elevation to be 1-2mm lower than the adjacent asphalt concrete pavement and shall not exceed the pavement elevation.
The important reason for the stability of the grouting pipe reinforced soil subgrade is to further verify the main principle of the grouting pipe reinforced soil subgrade treatment technology. It is to place various types of grouting pipe products inside, on the surface of the soil mass or between the layers of soil mass. Relying on the tensile characteristics of the grouting pipe, the distribution of the internal stress field and displacement field of the reinforced soil mass is changed through the friction and embedment between the grouting pipe and the surrounding soil mass.
Chemical grouting chemical grouting materials are mainly used in water glass and organic polymer grouting materials.
Saint Jerome .Reusable grouting pipe: it can be used for many times, and the grouting is not limited by time.
(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.
Most of the grouting pipes on the market are 6 meters in stock, 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 100 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, 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.
