First, the product description: 
 Extubation is a rubber pumping concrete for the new small-diameter holes into the core module, it mainly as a bridge to form small holes designed PC can also be used for other concrete construction industry into the hole. It is the use of its high strength, high flexibility and performance of rubber incompressibility, the axial force in the tube when the axial elongation and radial curved and thin. Pulling a powerful, convenient construction, can be used repeatedly, long life, smooth surface, roughness, and set aside hole wall smooth, and pulls out to be free from restrictions on setting time of concrete economic benefits are obvious. 
 Second, pumping extubation Features: 
 1, the repeated use of up to 100-200 times, cost-effective, reducing construction costs. 
 2 hole wall smooth, accurate size, high precision hole 
 3, in the initial setting of concrete can be drawn any time pull 
 4, human, hoist, construction vehicles can Pulling 
 5, can be bent into a bundle of paper, transport, preservation are very convenient 
 Third, use: 
 Pumping method is very simple to use extubation, tracheal extubation using a fixed ring would draw in the correct location on the fixed, fixed-ring hanging intervals to be able to control subject, generally about 300-500mm. Pouring concrete until concrete can be solidified Pulling, such as to reduce the number of fixed-ring can be extubated in the pumping hole penetration in a certain diameter of steel. Pulling tool: hoist, construction vehicles. 
 Pulling out should be reinforced, and then be drawn on the pull rods. If hole is reserved with the curvature of the (limited to a single arc) or a long hole components, can be drawn from the two concrete pull method. Then be sure to pay attention to the joints closed tight, not poured into the mortar to form anchor head. 
 IV Precautions 
 ★ Do not Pulling back to power, has been drawn to pull out, until all pulled out. 
 ★ Do not coated surface extubation pumping oil release agent. 
 ★ pumping extubation in use for some time, check whether there are scratches on the pumping crack extubation, such as along the axial cracks do not affect use. If there are cracks along the radial depth of 2mm or more, please stop using it. 
 When not in use to avoid ★ temperature, sunlight and contact with corrosive materials
