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,Burgas48lead small conduit, 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,Burgasmanufacturer of composite anchor rod, 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.The longitudinal overlapping width of grouting pipe and grouting pipe shall not be less than cm, and the transverse overlapping width shall not be less than cm. The former shall be placed on the latter according to the asphalt paving direction. After laying the glass fiber grouting pipe, fix the glass fiber grouting pipe with high-quality cement nails and fixed iron sheets with a size of mm, mm and a thickness of .mm. The fixed spacing can be determined according to the actual construction situation.Burgas, advantages: Simple installation, complete set; The grouting pipe can be intercepted at the construction site according to the actual required length of the joint (it is recommended that the longest grouting outlet length should not exceed m); No special installation equipment is required; fourWhen 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, and also due to the pipe mouth not being closed well and falling debris, 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, so it is impossible to comprehensively test the whole pile and judge the quality of the pile foundation!Richards Bay, The saddle shaped curved surface on the horseshoe surface of the grouting pipe and the upper and outer molds are not well fitted, low gas permeability strong sealing and no leakage.On site inspection of grouting pipe: Before on-site inspection, measure the delay time from the sound wave monitor to the receiving system. And calculates a sound time correction value.There are many forms of grouting pipes that can be improved and applied. Although the engineering pipeline system is very complex, any complex pipe system can be divided into several relatively simple individual pipe sections through the setting of fixed pipe racks. When selecting the corrugated grouting pipe, the deformation compensation of the pipe system can be determined according to these relatively simple pipe sections, so as to select the grouting pipe.Application process,In recent years, there have been frequent natural disasters, such as mountain slides, floods, 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, cement pavement and subgrade reinforcement, railway subgrade, embankment slope protection airport runway, or manually.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,BurgasAdvance small conduit and pipe shed, 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.Disposal method: the grouting pipe shall be shortened according to the specification.

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 mm. 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 its steel beam shall be adjusted according to the longitudinal, transverse slope and elevation to be ~ mm lower than the adjacent asphalt concrete pavement and shall not exceed the pavement elevation.Quality improvement, The length can be matched according to the construction requirements, without loss. Rigid inner core: it will not be flattened under concrete pressure to ensure smooth grouting channel.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.Burgas,Advantages: It is connected with special hydraulic tongs, does not require preparations outside the construction site, does not require any equipment, is convenient and fast ( times faster than the traditional welding method), is simple to fix the grouting pipe to the reinforcement cage, and is not affected by the bad weather.Plastic pipe plastic pipe has a low acoustic impedance which is used as a grouting pipe and has a large acoustic transmission rate. It can usually be used for smaller cast-in-place piles. It should be cautious when used in large-scale cast-in-place piles - because large-diameter piles need to be poured with a large amount of concrete, and the hydration heat of cement is not easy to dissipate. In view of the great difference between the thermal expansion coefficient of plastic and concrete, the plastic pipe will shrink radially and longitudinally due to the temperature drop after concrete solidification, It may be separated from the concrete locally to cause air or water crevices, and add more strong reflection interfaces on the sound path, which is easy to cause misjudgment.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.
