Grouting sleeve grouting detector and detection method

Abstract

The invention belongs to the technical field of grouting, and discloses a grouting sleeve grouting detector which comprises a bearing assembly, the bearing assembly comprises a sliding cavity, a moving assembly is slidably arranged on one side of the sliding cavity, and the end, away from the moving assembly, of the sliding cavity is connected with a communicating assembly used for being connected with a grout outlet. The bearing assembly is fixedly provided with an air pressure detector used for monitoring the air pressure change condition in the sliding cavity. The piston compresses the air space in the sliding cavity and the mold, so that the air pressure in the mold is increased, slurry in the injection molding process is pressed through the air pressure when the grouting pump is used for grouting, it is ensured that the whole part in the mold can be filled with the slurry, and the grouting efficiency is improved. Meanwhile, whether the mold is filled with the slurry or not is judged through air pressure indication of the air pressure detector and the slurry at the front end of the communicating pipe, the quality is guaranteed, the plumpness of the slurry in the grouting sleeve reaches the standard, the slurry is denser, and the engineering quality is improved.

Description

technical field [0001] The invention belongs to the technical field of grouting, in particular to a grouting sleeve grouting detector and a detection method. Background technique [0002] At present, the state and local governments are vigorously promoting industrialized buildings. Industrialized buildings represented by prefabricated concrete structures are an important direction for the reform and development of the construction industry. Civil buildings, especially residential buildings, will use a large number of prefabricated concrete structures. Due to the change of construction methods, the relevant basic research and engineering practice are insufficient, especially in the quality acceptance link, there are still many technologies and methods that need to be improved and perfected. [0003] The patent No. 2018222349085 is a sleeve grouting fullness observer with scale lines. Although the pouring situation in the sleeve can be observed by observing the slurry height ...

Problems solved by technology

[0003] The patent No. 2018222349085 is a sleeve grouting plumpness observer with scale lines. Although the pouring condition in the sleeve can be observed by observing the height of the slurry in the connecting pipe, but at the same time, due to the use of the transparent observer It is a disposable product, and the material is a plastic material that is not easy to decompose, so it is used in large quantities during the pouring process, and the number of uses is large, resulting in high cost of use. At the same time, it is easy to cause environmental pollution when the transparent observer is discarded after use.

[0004] In the traditional grouting process, it is impossible to visually observe the injection and filling conditions of the slurry in the mold, so it is impossible to judge whether the slurry in the mold is completely filled, which will easily lead to incomplete filling of the cavity in the mold and affect the The load-bearing capacity of the grouting structure in the subsequent use affects the overall safety of the prefabricated house
