Description

Technical Field

[0001] The utility model relates to the technical field of reinforced concrete main structure construction in civil engineering, in particular to a device for detecting the quality of steel bar planting holes, cleaning holes and forming holes. Background Art

[0002] Post-anchored reinforcement technology is a new type of reinforcement technology, including chemical reinforcement, chemical anchor bolts, expanded bottom mechanical anchor bolts, expansion anchor bolts, etc. Chemical reinforcement is commonly used in engineering. By drilling holes on the surface of the concrete structure and injecting reinforcement glue, the steel bars are implanted into the holes, and the bonding force between the steel bars and the reinforcement glue is used to improve the bearing capacity and earthquake resistance of the structure. Compared with traditional reinforcement methods, post-anchored reinforcement technology has the advantages of convenient construction, significant reinforcement effect, and a wide range of applications, so it has broad application prospects.

[0003] At present, the post-anchoring reinforcement process is: positioning and setting out → drilling → hole cleaning → injection of reinforcement glue → reinforcement → maintenance and testing. Post-anchoring reinforcement is mostly used in secondary structures and existing structure repair and reinforcement projects, but at present, the quality indicators such as the depth of the reinforcement hole and the verticality of the hole are generally not taken seriously enough. Considering the seismic performance requirements of the structure, during the reinforcement construction process, after the hole is opened, it is necessary to test and verify the hole indicators, so as to ensure the overall quality of the reinforcement from the source.

[0004] At present, after the reinforcement holes are drilled and formed, manual hole cleaning is generally adopted. The operator inserts a rubber hose into the reinforcement hole and compresses the air in the hole by blowing air to achieve the purpose of cleaning the reinforcement hole. This method has the problem that the hose may not be able to reach the deepest part of the reinforcement hole, resulting in incomplete hole cleaning; and this hole cleaning method is easy to cause the dust blown out to enter the operator's mouth and nose, thereby affecting the operator's health. Utility Model Content

[0005] The utility model aims to provide a device for cleaning and inspecting the quality of holes for rebar planting, so as to solve the problems that the quality inspection of rebar planting holes is not carried out in the prior art, and the existing hole cleaning method is not thorough enough, which affects the health of operators.

[0008] After the utility model connects the depth measuring rod with the level measuring device, the hemispherical end of the depth measuring rod is inserted into the rebar hole, and the depth and level of the rebar hole can be measured simultaneously. Since the two are detachably connected, they can be easily disassembled and installed. After removing the level measuring device, the depth measuring rod is connected to the air compression device. Since a through hole is provided on the depth measuring rod, the through hole serves as an air transmission channel. The air compression device provides gas, and the gas is blown into the rebar hole through the air transmission channel to achieve the purpose of hole cleaning. The above technical solution can be used to conveniently detect the quality of rebar hole formation, and at the same time improve the hole cleaning quality. This hole cleaning method avoids affecting the health of operators.
