A composite tooth grouting head restorator and its restoration method

Abstract

The invention discloses a composite tooth grouting head re-regulator and a re-regulation method thereof. The re-regulator is composed of a support (1), a vertical sliding groove (2), a magnetic force attracting grouting piece (3), a grouting head mandrel rod (4), a grouting head connecting piece (5) and a counterweight plate (6). When a composite tooth grouting head (7) is embedded in a pre-formed hole of a pipe sheet (8), the grouting head connecting piece (5) on the grouting head mandrel rod (4) is in threaded connection with the composite tooth grouting head (7) and is placed in the needed position in the pre-formed hole of the pipe sheet (8), then the grouting head mandrel rod (4) is arranged in the vertical sliding groove (2) with the magnetic force attracting grouting piece (3), and the composite tooth grouting head (7) is kept stable and vertical through the magnetic force attracting grouting piece (3) and the vertical sliding groove (2). At this time, sizing agents are poured into the hole in which the composite tooth grouting head (7) is placed, after the hole is filled with the sizing agents, the support (1) is moved away, the next embedding operation can be performed, and after the sizing agents are solidified, the grouting head mandrel rod (4) is screwed out. The composite tooth grouting head re-regulator and the re-regulation method thereof are significant in efficiency and high in quality product rate, overcome the defects that the composite tooth grouting head (7) is not straight in embedding operation, low in efficiency and high in waste product rate, and are suitable for the embedding operation of the pipe sheet composite tooth grouting head.

Description

technical field [0001] The invention relates to a building construction device, more specifically, the invention relates to a device for repairing a grouting head of a composite tooth and a repair method thereof. Background technique [0002] During the construction of subways, light rails, and tunnels, building segments are generally prefabricated. This prefabricated segment often has a preset grouting head for hoisting and grouting after hoisting. The preset grouting head must be vertical, otherwise it will bring troubles for hoisting and grouting. A segment whose grouting head is not vertical means that the entire segment is scrapped, and the resulting economic loss ranges from a few thousand yuan to tens of thousands of yuan. However, in the current operation process, all are implanted by hand, which is not only inefficient, but also has a high reject rate. So far, there is no more advanced and applicable method to embed the segmental grouting head. Contents of the ...
