Description
Technical Field
The invention belongs to the field of civil engineering test equipment, and particularly relates to solid structure concrete powder taking equipment.
Background
Concrete experts at home and abroad and engineering practice show that the premature failure of the structure caused by the corrosion of the steel bars caused by the chloride is the most main failure mode. In recent decades, most methods for characterizing the chloride ion permeability resistance of concrete are used for testing the invasion speed of chloride ions under the action of an electric field, and the fast test result is greatly different from the invasion rule of chloride ions in a solid structure.
In order to know the concentration distribution rule of chloride ions in solid structure concrete in time and make an economic structural durability redesign scheme as soon as possible, the method has great significance for reducing the cost of the whole life cycle of a structure, and the method is also the target of long-term research of experts in the civil engineering field at home and abroad. At present, the detection of the chloride ion concentration distribution of concrete with an entity structure is divided into two types, one type is that a batch of core samples are taken by the entity structure on site, then the core samples are concentrated to be ground, both the core taking and the grinding are concentrated operation, after a batch of core samples are accumulated, the chloride ion concentration at each depth is tested, and the core samples drilled on site are greatly higher than the actual ground depth according to the fixture operation requirement of indoor grinding, so that the damage to the entity structure is large; in the other type, the powder is directly taken by drilling a hole by using a handheld impact drill on site, but due to the fact that the diameter of the drilled hole of the impact drill is small and vibration of the impact drill in the drilling process is added, a deep powder sample can touch concrete on the surface, and a large number of tests prove that the concentration of aggressive media such as chloride ions in surface concrete is much higher than that in the interior, particularly under the condition of short service life, such as 5 years and 10 years, the representativeness of the taken powder sample is greatly reduced. The second type of method also has the following drawbacks: 1) in the process of drilling powder, an operator needs to constantly measure the drilling depth and frequently stops the drilling machine when the drilling depth is close to the required depth so as to ensure that a powder sample is in a set depth range, so that the drilling efficiency is low; 2) the operation range of the drill bit is limited by a not too thick annular steel base plate, but in the actual powder drilling process, the drill bit inevitably touches the edge part of the surface layer, the powder sample of the surface layer has obvious influence on the test results of the powder samples of the lower layers, and the test results are distorted because the drill bit does not touch the upper layers in the process of drilling and grinding the lower layer; 3) the manual operation causes the drilling speed of the drill bit to have great randomness, and directly causes the fineness difference of the drilled and ground powder samples (from several micrometers to 1mm), and the particle size of the powder sample has a remarkable influence on dissolved chloride ions in the appointed time period of dissolution in an acidic solution or water; 4) after the layer is drilled and ground, the machine needs to be stopped, the drilled and ground powder sample is collected and taken out, the existing equipment is difficult to clean the powder sample, the powder sample of the upper layer is randomly mixed in the powder sample of the lower layer, and the specific content is not influenced definitely, so that the test result is distorted. In addition, the existing powder drilling equipment has the defects of low control precision, large test error, low operation efficiency, high labor intensity of workers and the like, and cannot adapt to the powder drilling work of large batches of test pieces.
It will thus be seen that the prior art is susceptible to further improvements and enhancements.
