The wellhead clamp head is connected to the lower clamp head of the drive head. Some driving of grouting pipe. The cooperation Specification between the saddle profile on the horseshoe of the grouting pipe and the core is too low. When the outer mold and the horseshoe surface are fitted together, the gap is larger than the thickness of the pipe wall, that is, there is an active gap. Therefore, the Chengdu grouting pipe manufacturer kneads the pipe wall to form an 'eight' shaped wrinkle.Pargas ,Grouting parameters such as grouting pressure and reinforcement radius can be determined through field tests according to geological conditions and engineering requirements. Grouting holes are generally arranged in an equilateral triangle or rectangle on the plane. The reinforcement radius of collapsible loess is generally .-.m, and the reinforcement depth is generally -m. The advantage of silicification method is that the grout has strong permeability and can quickly terminate the deformation of the foundation; It is non-toxic, does not pollute the environment, and is cheap, so it is widely used.Causes of wrinkling: the blanking specification of pipe joint is too long.Ath Thawrah,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 is a patented product. Compared with similar products in the market, it has higher tensile resistance and better sealing performance.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, water and other impurities when using the prestressed machinery. The working clip can be used after removing the foam in the packing box, when the prestressed tendon is long and the grouting pipe needs to be tensioned repeatedly, which is not only conducive to the follow-up and anchor pulling of the working clip, 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 electric double fluid silicification method is suitable for strengthening soft clay foundation with permeability coefficient less than .m/d. The grouting pipe with holes is used as the anode, the pore water diffuses from the anode to the cathode, and the solution flows from the anode to the cathode along with the movement of water, so that the grouting effect is improved. The reinforcement cost of this method is high, and it can only be used after it is confirmed to be effective by tests.The alkali solution method is to heat the sodium hydroxide solution (alkali solution) to ~ ℃ and pour it into the soil layer through the grouting pipe with holes under its own weight. When the content of calcium and magnesium ions in the soil is high (such as loess), the surface of the soil particles will be activated and self cemented, so as to improve the strength and water stability of the soil, which is called the single solution method; When the content of calcium and magnesium ions in the soil is less (such as general cohesive soil)Appropriate measures shall be taken to prevent surface water, 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,Pargas Pile bottom grouting pipe, 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.investment,They shall be connected as a whole in the factory as far as possible. If it is necessary to connect on site due to manufacturing process transportation conditions, etc., hot press vulcanization (grouting pipe) or welding (plastic grouting pipe) shall be used. The joint appearance shall be smooth and smooth, and the tensile strength shall not be less than % of the base metal. The so-called 'overlapping' without any treatment is absolutely not allowed. All kinds of cross connection points of grouting pipes shall be made of accessories produced by our new rubber products factory, so as to ensure that on-site connection is only carried out in straight sections during construction. Flexible material with sufficient deformation capacity and good adhesion with concrete. Low cost, fast time, no loss, free from climate and place constraints. The length can be matched according to the construction requirements, without loss.

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, 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,Pargas Advance small conduit and pipe shed, 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.build,In the engineering practice, some construction units directly pave the glass fiber grouting pipe after spraying the sticky layer oil, and the roller rolls after it. The effect is good, and the glass fiber grouting pipe is not easy to wave. Strictly control the entry and exit of vehicles transporting the mixture, and forbid vehicles to swerve, brake and dump the leftover mixture on the grouting pipe layer to prevent damage to the glass fiber grouting pipe; The back glue of glass fiber grouting pipe is easily soluble in water, and construction shall not be carried out in rainy days or wet roads; Glass fiber grouting pipe is made of grouting pipe, which is easy to irritate human skin. Construction personnel must wear protective gloves; When the grouting pipe is laid, the temperature of the road surface is required to be between . Therefore, the relative displacement trend or relative displacement will occur between the narrow two, which will then generate friction. This friction is generally called 'surface friction'. 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, the drilling and grouting continue to be continued downward and injects a section of grout. After each section of grouting, 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.Answer: Yes, it can be protected. The piston rod can be protected by adding plastic hoses or bellows within the travel range.Pargas ,How to deal with the joint if the grouting pipe is installed in sections?

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 applicable to the laying of buried pipes in gas pipeline projects, and is not applicable to the use of open pipes. The service life of pipes will be affected by the perennial ultraviolet corrosion of sunlight. How to use the grouting pipe after rusting will not affect its . The grouting pipe is a kind of rubber plate we often see. It is widely used and has a long service life. It has been praised and recognized by people. Next, I will introduce the relevant knowledge of the grouting pipe we produce in detail!The stability of the grouting pipe is one of the important factors to control the stability of the whole foundation pit. Its erection must be accurate and in place, and prestress must be applied in strict accordance with the design requirements. In particular, attention should be paid to the stability of the diagonal bracing. During the diagonal bracing operation, every link of the installation must be carefully operated. At the same time, the steel purlin must also ensure its stability, strength and deformation requirements during the production and installation process. In addition, During the whole construction process from foundation pit grouting pipe erection to removal,Pargas Tunnel combined hollow anchor manufacturer, the grouting pipe must be strictly monitored to ensure its stability. How to improve the bearing capacity of piles with grouting pipes in bored piles, during the drilling process of large-diameter cast-in-place piles, the soil layer around the piles will become loose due to the agitation of the turning heads. In addition, the water immersion makes the soil layer that has started to loosen more loose. This problem can be effectively solved by grouting with grouting pipes. How to improve the bearing capacity of piles when grouting with grouting pipes?
