CONCRETE CONSTRUCTION TECHNIQUE CAPABLE OF CONTROLLING SETTING TIME AND SPECIAL EQUIPMENT THEREFOR

摘要

Present invention involves a setting time controlled concrete construction method and its dedicated equipment, it provides construction method and dedicated equipment for 3D printing concrete forming and normal concrete forming. Construction technology includes mixing, pumping, extruding, forming, coagulating and hardening steps, between pumping and extruding, there is an electric treatment step to concrete by applied electric field, mixture processed by applied electric field will be extruded immediately through extrusion port; Dedicated equipment comprises a delivery pump, a delivery pipeline, an extrusion device; The extrusion device comprises an electric treatment device and an extrusion port. The construction technology and equipment adopting this technical solution may achieve the effect of quick adjusting concrete setting time, rationally improve early strength of concrete, capable of adjusting and controlling setting time of concrete before forming, also it keeps good fluidity of prepared concrete before forming, to satisfy demand for agitation and delivery.
