Abstract

A sleeve grouting plumpness detection device and its use method, comprising a grout filling device pipe body, variable-diameter taper openings and sealing caps respectively arranged on both sides of the grout replenishing device pipe body, and movable plugs arranged in the grout replenishing device pipe body The head and the sliding connecting rod fixedly connected with the movable plug head, there is a slurry inlet channel in the tapered mouth, and the two ends of the inlet channel are respectively connected with the grouting sleeve and the pipe body of the grouting device; the outer diameter of the tapered mouth is from The entrance of the grouting material becomes larger gradually, and the movable plug and the sliding connecting rod are provided with an exhaust channel that runs through. One end of the exhaust channel is connected with the slurry inlet channel, and the other end is connected with the atmosphere. 1. An elastic piece is sleeved on the outer side of the sliding connecting rod, and the sliding connecting rod is provided with a zero point mark for observing the fullness of grouting and a grouting mark for observing whether the grouting is complete. The invention reduces the workload of the grouting workers and reduces the work difficulty of the quality inspectors, the grouting quality supervision is intuitive and convenient, and full inspection can be achieved.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to a sleeve grouting fullness detection device and a use method thereof. Background technique [0002] In prefabricated concrete structures, the reliable connection of stressed steel bars between prefabricated components is the key to determining the safety of the structure. Most of the vertical connection of stressed steel bars in assembled monolithic concrete structures at home and abroad adopts the connection method of sleeve grouting. The structure of steel sleeve grouting connection is complex, and it is also a hidden project. The key link of safety, its construction quality is very important. However, there is currently no effective control measures. The non-destructive testing technology of grouting sleeve grouting fullness is a recognized difficulty at home and abroad, and conventional ultrasonic, infrared imaging, geological radar and other methods cannot be effectivel...
