Description

Technical Field

[0001] The utility model relates to the field of anti-floating anchor rods, in particular to a tension-type expanded-body bladder-type anti-floating anchor rod for preventing leakage of a basement floor. Background Art

[0002] At present, there are problems with common anti-floating anchor rods: During the waterproofing construction of the basement floor of the anti-floating anchor rod, if the corresponding measures are not taken to waterproof the nodes of the anti-floating anchor rods, it is easy to cause leakage of the concrete at the nodes of the anti-floating anchor rods and the basement floor due to the occurrence and development of capillary channel phenomena. Some projects were originally designed to meet the anti-floating requirements according to the geological survey report, but after the main structure of the project was completed, due to the large deviation between the rainfall in the rainy season in the area and the rainfall in the same period in the past, there was a rainfall that was rare for decades or even a hundred years. After measuring the groundwater level, the water level rose and did not match the geological survey water level, resulting in the structural design not meeting the anti-floating requirements. In order to avoid structural damage due to insufficient anti-floating force, considering the construction cost, convenient and fast construction, anti-floating requirements and leakage problems, it is necessary to construct the anti-floating anchor rods later. The pull-out bearing capacity of conventional anti-floating anchor rods does not meet the requirements of groundwater buoyancy. Utility Model Content
