Cement grouting material construction joint solution - Grouting material models

Cement grouting material type grouting material model CGM high-strength non-shrinkage grouting material model construction site, construction of concrete grouting material models of often due to skills or equipment, the limitation of manpower, cement grouting material models can't continuous casting, stagnation point beyond the promise of intermittent moment, shear force is needed at this time in the structure of small and easy to construction site construction joint lien, but until the next cement grouting material type casting, must be to deal with construction joints. The solution generally have the following; One, MAO to adopt double-layer steel wire net foreign stretched reinforcement or the wood reinforcement as a 'template' lien of construction joint, can be in cement grouting material models after the initial setting, cut off the wire mesh, with MAO's way to deal with. Second, the hair in the casting of cement grouting material model after the initial setting changchun early strength grouting material model, in the construction joints of cement grouting material pull model looks over to shallow groove, interspersed with 10 ~ 20 mm deep, also can make the construction joint models looks rough cement grouting material. This method can greatly improve the construction joint processing speed, reduce labor intensity, but laitance and loose stones in addition to do not easily, the effect is inferior to cut hair. 3, 1, cut depth MAO MAO take 10 to 20 mm, not too light. 2, using artificial cut hair, time shoulds not be too long, or cut hair is difficult, if the strength of cement grouting material model is too high, can use pneumatic hammer chisel. 3 take off cement grouting material, construction joints model block and template has no completed stay grouting material under the model of sawdust, tie wire, card buckle and other sundry, must rely on artificial or air compressor to clear clean.
