How heavy is a grouting pipe?In China, the types of grouting pipes are relatively complete now from grouting pipes and grouting pipes for Reinforcing Subgrade to glass fiber grouting pipes for highway pavement, to convex joint grouting pipes and plastic tensile grouting pipes for railway. For different road construction environments, different types of grouting pipes are selected, which can not only ensure the quality of the road but also save the cost. So what kind of application effect can the grouting pipe achieve in highway maintenance? The grouting pipe manufacturer will take you to have a look.GuaimaroPolymer chemical grouting method is applicable to reinforcement of sandy soil foundation, curtain grouting of dam foundation, water stop and leakage stoppage of underground engineering,GuaimaroGrouting small conduit, reinforcement of muddy interlayer of dam foundation and fault fracture zone. There are many varieties of polymer chemical pulp materials, including epoxy resin, acrylamide (propionate), polyurethane (cyanogen), 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.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.Kyongju, The length can be matched according to the construction requirements, without loss.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, which can be set in the basement according to the above method, or set outdoors as a temporary facility. Usually, 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.When the pipe cannot be connected due to serious blockage,GuaimaroGrouting pipe grouting, 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. Common problems and answers of grouting pipe what is the pressure inside the grouting pipe?

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, so that the soil has better overall shear strength and bending stiffness. Slump test shall be carried out for concrete entering the site. No less than groups of test pieces shall be made for the same batch of concrete with the same strength grade. One group is used for standard curing, and the other two groups are used for curing under the same conditions to determine demoulding and allowable lifting time.In recent years, there have been frequent natural disasters, such as mountain slides, floods,GuaimaroAdvance small conduit for tunnel, earthquakes, fires, etc. we are so small in the face of natural disasters that we can only devote our efforts to normal prevention and post disaster rescue. The grouting pipe can reduce the damage caused by these natural disasters.Grouting pipe is an expert in road construction. It can connect the subgrade as a whole and improve the bearing capacity of the subgrade. When encountering natural disasters, the subgrade will not be greatly damaged due to natural disasters, so that we can save more people in the rescue work. The grouting pipe can also play a great role in slope protection. The use of the grouting pipe can well prevent the landslide of mountain soil and debris flow disasters. Through many years of practical experience, it has been proved that the roads that usually use the grouting pipe are far more than the same period of projects in terms of service life and quality. Thus reducing the casualty rate. Grouting pipe is a kind of excellent geosynthetics used for Pavement Reinforcement, old road reinforcement, subgrade reinforcement and soft soil foundation reinforcement. It has become an irreplaceable material in the application of asphalt pavement reflection crack treatment. This product is a semi-rigid product made of high-strength alkali free grouting pipe, which is made of mesh base material through internationally advanced warp knitting process and surface coating treatment. It has high tensile strength and low elongation in both longitude and latitude, and has excellent properties such as high temperature resistance, low cold resistance, aging resistance and corrosion resistance. It is widely used in asphalt pavement, cement pavement and subgrade reinforcement, railway subgrade, embankment slope protection, airport runway, sand prevention and control projects. Grouting pipe laying and fixing of grouting pipe laying of glass fiber grouting pipe can be carried out by special equipment refitted from tractors or automobiles, or manually.Total quality assurance The grouting pipe is padded with the front lip of the horseshoe, so as to improve the physical and mechanical properties of the bearing layer of the pile body Especially for the ballast at the bottom of the pile, grouting can improve or eliminate the adverse effect of the ballast at the bottom of the pile on the end bearing capacity through the replacement compaction and consolidation of the ballast by the slurry.II During the drilling process of the bored pile, which will lead to the decrease of the pile side friction and affect the bearing capacity of the pile When the grouting pipe is used at the pile end for grouting, the slurry will permeate, fill and compact along the side of the pile under the pressure, so as to complete the replacement of the mud skin around the pile and the filling of the gap, such as greatly improving the pile side friction resistanceThe grouting pipe with the grouting pipe as the core flexible element can be compensated in the axial, lateral and angular directions on the pipeline. From the perspective of its performance, the internal pressure grouting pipe can be displaced in three directions, but because it is limited by casing and other accessories, it can often only be displaced in the axial direction. Therefore, the user needs to indicate the displacement in several directions when selecting and ordering, so as to select correctly. The working principle of the grouting pipe is to use its own elastic deformation to compensate the axial, angular, lateral and combined displacement of the pipe due to thermal deformation, mechanical deformation and various mechanical vibrations. The compensation has the s of sealing, pressure resistance, temperature resistance, corrosion resistance, impact resistance, vibration reduction and noise reduction, which can reduce the deformation of the pipe and improve the service life of the pipe.
