Abstract

The invention provides a prefabricated segment bubble removal vibrating method. Specifically, according to the prefabricated segment bubble removal vibrating method, a plurality of transverse vibrators are arranged on a mold to substitute for artificial vibrating bars in the prior art; through cooperation between longitudinal vibrators and the transverse vibrators, concrete in longitudinal and transverse directions and the surface of the prefabricated segment mold can generate relative movement during a concrete pouring process; during vibration, concrete mortar can be adhered to the surface of the mold, bubbles on the surface of formed prefabricated pieces can be covered by the concrete mortar, so that the transverse forming quality of prefabricated segments can be improved, and the problem of bubbles in the transverse direction of the prefabricated segments can be solved. The prefabricated segment bubble removal vibrating method can reduce the number of bubbles in the transverse direction of the prefabricated segments by around 93% compared with methods only applying the longitudinal vibrators. The prefabricated segment bubble removal vibrating method solves problems from a distinctive angle, and by adding a transverse vibrating source, achieves treatment on the bubbles in the transverse direction through a vibrating covering mode. The prefabricated segment bubble removal vibrating method is simple in manufacturing of required units, significant in effects, low in investment, applicable to construction operation and management and convenient to popularize and implement.

Description

technical field [0001] The invention relates to a vibrating method for producing a segment, in particular to a vibrating method for removing air bubbles in the production of a prefabricated segment. Background technique [0002] With the continuous expansion of the scale of modern city construction, the subway, as an effective means of transportation, can solve the problem of excessive urban traffic pressure. At this stage, subway segments are generally made by prefabrication. In the process of making subway segments, it is found that the elimination of air bubbles on the surface of precast concrete is an urgent problem to be solved. People have analyzed the prevention and treatment of air bubbles, a common quality problem in the production of prefabricated segments, from many aspects. For the research on vibration methods, the existing technology is to produce prefabricated segments through the cooperation of longitudinally attached vibrators and artificial vibrating rods....
