Grout leakage detection device and method for grout sleeve

Abstract

The invention discloses a grout leakage detection device for a grout sleeve. The grout leakage detection device comprises a pressure pipe, a connecting pipe and a valve; the pressure pipe comprises amounting pipe segment inserted into an injection hole and a detection pipe segment connected with the mounting pipe segment; the outer surface of the detection pipe segment is provided with a sealingportion for sealing a gap between the injection hole and the mounting pipe segment; the detection pipe segment is provided with a pressure gauge for detecting the pressure of the pressure pipe; one end of the connecting pipe is connected with a grouting pipe; a grouting opening connected with the detection pipe segment is formed in the other end of the connecting pipe; and the valve is connected between the pressure pipe and the connecting pipe. The invention also discloses a grout leakage detection method for a grout sleeve. According to the grout leakage detection device and grout leakage detection method for the grout sleeve of the invention, the grout sleeve is adopted to realize grouting connection, the grout leakage condition of the grout sleeve is detected timely through the grout leakage detection device; a grout leakage position is timely checked and repaired; the injection of a grouting material is supplemented; and therefore, the problems of poor load-bearing capacity and seismic performance of an connected assembled structure which are caused by the decrease of the plumpness of the grout sleeve which is further caused by the grout leakage of the grout sleeve can be avoided.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a grout leakage detecting device and method for a grouting sleeve. Background technique [0002] The grouting sleeve is to insert the threaded steel bar into the metal sleeve, and then pour the high-strength grouting material mixture, and use the bonding and anchoring formed between the grouting material to solidify and the threaded steel bar to transfer stress to realize the butt joint of the steel bar. One of the most important connection methods. When the grouting sleeve is used for connection, the density of the grouting material inside the sleeve is a key factor affecting the connection quality and force transmission performance, and determines the overall bearing capacity and seismic performance of the assembled structure. [0003] For the construction of the steel sleeve grouting connection, although the specifications and related technical regulations have made deta...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to provide a grout leakage detection device and method for grouting sleeves, aiming to solve the problems in actual engineering, such as the looseness of plugging plugs at the grouting port and the grouting port, and the sealing of the grouting layer. Due to the lack of tightness and other reasons, the grouting sleeve has grout leakage after grouting, the fullness of the grouting sleeve is low, and the technical problems of the assembled structure after connection are poor in bearing capacity and seismic performance.
