Series circulating grouting device and grouting method

Abstract

The invention discloses a tandem circulating grouting device and a grouting method. The device includes a grout storage tank, a grouting pump with a pressure gauge, several prestressed pipes, a grouting port valve, a grouting port valve, a grouting port Consistency detector, grout consistency detector and grouting pipe, prestressed corrugated pipes are distributed in parallel in the concrete prestressed member, several prestressed corrugated pipes are connected in series to form prestressed pipe group, grout storage tank, grouting pump and prestressed The pipe groups are connected in series through the grouting pipes to form a circulation loop. The grouting port valve is set on the grouting pipe between the grouting pump and the prestressed pipe group, and the grout outlet valve is set between the prestressed pipe group and the storage tank. On the grouting pipe between the grouting pipes, the inlet consistency detector is set on the grouting pipe between the grout storage tank and the grouting pump or on the grouting pipe between the grouting pump and the prestressed pipe group, and the grouting consistency detector Set on the grouting pipe between the prestressed pipe group and the grout storage tank, it can ensure the compactness of the grouting through circulating grouting and prevent the grouting pipe from being blocked.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a serial circulation grouting device and a grouting method. Background technique [0002] In building construction, the prestressed corrugated pipe is pre-embedded in the concrete prestressed component. After the concrete is poured and the concrete reaches a certain strength, the prestressed corrugated pipe is threaded into the prestressed tendon (such as a steel strand). After the prestressed tendons are stretched and anchored, the prestressed corrugated pipe channel is grouted to fill the gap between the prestressed tendons and the channel, so that the prestressed tendons and the concrete are firmly bonded together, and the strength and stiffness of the concrete components are improved. And bending resistance, to prevent premature cracks in concrete components. [0003] The traditional grouting process often has technical problems such as blockage of the grouti...
