 To solve a technical bottleneck problem has been restricting the development of the fabric machine fabric machine piping life, reduce the plugging phenomenon, to improve the quality of the pouring of concrete for the further promotion of fabric machine of great significance. 
 The stiffness and the wear resistance of the rubber and plastics, nylon cone structure is very difficult to solve two problems. Perhaps repeated numerous times to adjust the material formulation and structure size, may be a large gap between the anti-static sealing from the Chi device, but because of the rigidity of its structure is not adjusted, so may only be for a particular pipeline gap. In order to apply to different pipe gap is difficult to achieve. Stiffness weakened due to wear can not be solved. 
 PM nylon anti-segregation device, the elastic is too small only applies to the concrete pump truck, can not be used to arm large gap between the decline in the fabric machine working conditions. PM nylon anti-segregation device based on the development of anti-segregation device for fabric machine. Must first study the difference between the work of the concrete pump truck with spreader. The concrete pump is the mechanical work on the ground, its fabric arm they use to move the top of the gesture operation, only the end of the hose for the decline in the pipeline, the gap is about 4m. Fabrics machine (whether it is climbing tower fabric machine or fabric machine) is located above the top of the building, machinery, cloth arm most of the bottom-forward posture job. In the actual casting operation, in order to avoid the reinforced frame as well as to avoid frequent lifting fabric machine is generally much higher than the buildings, so the drop pipe gap is often more than 10m. Fabric machine down the pipeline gap is much larger than the pump, the segregation problem is much more serious. Its support of the anti-segregation device must address the large gap between the static sealing a installation instructions to install the boom, according to the factory of the boom. 
 2, the boom stand straight, see if you can not weight to stand straight. (The boom in the general case to consider in not weight can stand straight, because of the lifting boom, the ordinary crane booms and with heavy with hanging up, need two to lifting installation ). 
 , Check the boom bolts tightened, the hinge is normal. 
 4, erection of booms placed in the location of the aircraft, and check acceptance, calculate the force parts of the rack on the capacity of the Twill reinforcement, foundation smooth.
