Abstract

The invention provides a vertical reinforcement sleeve grouting assisting device and method. A main body of the device is in a funnel shape, a backflow funnel on the upper portion serves as a temporary storage place of excess slurry during grouting, and the two ends of a guide pipe are connected with the backflow funnel on the upper portion and an upper slurry overflow hole of a sleeve on the lower portion respectively. According to the device, the situation that slurry overflows from a grouting hole in the lower portion and the liquid surface of the slurry in the upper slurry overflow hole islowered when a grouting head is pulled out from the grouting hole in the lower portion is considered, and the effective length of the slurry overflow hole is increased according to the thought of slurry overflow hole supplementing filling. During grouting, the excess overflowing slurry is temporarily stored in the guide pipe and the backflow funnel, and the slurry flowing out when the grouting head is pulled out is compensated by the excess slurry in the guide pipe and the backflow funnel, so that the fullness of the slurry in the sleeve is ensured.

Description

technical field [0001] The invention relates to a vertical reinforcement sleeve grouting auxiliary device and method. Background technique [0002] During the grouting connection construction of the existing vertical steel bar sleeve, grouting is done from one grouting hole, and the overflowing hole can be blocked only after the cylindrical slurry flows out of the grouting hole, and the grouting machine is stopped, and finally the grouting is blocked and grouted hole. During the gap between stopping the grouting machine and plugging the grouting hole, the slurry flows out from the grouting hole due to the influence of gravity, which causes the slurry in the sleeve to not be full. Contents of the invention [0003] The object of the present invention is to provide an auxiliary device and method for grouting a vertical reinforcement sleeve. [0004] In order to solve the above problems, the present invention provides an auxiliary device for grouting a vertical reinforcemen...
