[0068] combine Figure 6 , The invention provides a circulating grouting system, including a prestressed pipe group, a slurry storage tank, a high-pressure grouting pipe and a grouting pipe. The difference between this embodiment and the first embodiment is that the number of prestressed tube groups in this embodiment is four groups, while the number of prestressed tube groups in the first embodiment is two groups, and the others are not This is repeated.

[0069] Specifically, four groups of prestressed pipe groups are pre-embedded in prestressed concrete components. Four groups of prestressed pipe groups are arranged side by side and connected in series in sequence. The prestressed pipe group includes a first pipe and a second pipe arranged in the same direction. The first pipe is located below the second pipe. The first end of the first pipeline is formed with a slurry inlet 110 , the second end of the first pipeline is connected to the second end of the second pipeline...

Abstract

The invention provides a cyclic grouting system and a cyclic grouting method thereof. The cyclic grouting system comprises a plurality of prestressed pipe groups, a slurry storage barrel, a high-pressure grouting pipe and a slurry outlet pipe, wherein the prestressed pipe groups are pre-buried in a prestressed concrete member, are in side-by-side arrangement and are sequentially connected in series; each prestressed pipe group comprises a first pipeline arranged in the same direction as the prestressed pipe group and a second pipeline positioned under the first pipeline; a slurry inlet is formed in the first end of the first pipeline; the second end of the first pipeline communicates with the second end of the second pipeline; a slurry outlet is formed in the first end of the second pipeline; the slurry outlet of each prestressed pipe group communicates with the slurry inlet of the next prestressed pipe group; slurry liquid is stored in the slurry storage barrel; the first end of the high-pressure grouting pipe is positioned below the liquid level of the slurry liquid; the second end of the high-pressure grouting pipe communicates with the slurry inlet of the first prestressed pipegroup; a grouting pump is arranged on the high-pressure grouting pipe; and the slurry outlet pipe communicates with the slurry outlet of the last prestressed pipe group and the slurry storage barrelso as to form a circulation loop for slurry liquid grouting. The problem that uncompacted grouting often occurs during the construction in a conventional grouting process is solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a circulating grouting system and a circulating grouting method thereof. Background technique [0002] In building construction, the prestressed pipe is pre-embedded in the prestressed concrete member. After the concrete is poured and the concrete reaches a certain strength, the prestressed pipe is threaded into the prestressed tendon. After the prestressed tendon is tensioned and anchored, Carry out prestressed pipeline grouting, so that the grout fills the gap between the prestressed tendons and the pipeline, so that the prestressed tendons and concrete are firmly bonded together, improve the strength, stiffness and bending resistance of concrete components, and prevent the concrete components from appearing prematurely crack. The traditional grouting process often has the problem of not compacting the grout during construction. Contents of the invention [00...
