Background technology

Prefabricated assembled concrete structure has speed of application as a kind of structure type meeting industrialized production Soon, labor intensity is low, noise pollution and wet construction is few and the advantages such as product quality is easy to control, it has also become domestic and international construction industry development Main flow direction.2 months 2016《State Council of the Central Committee of the Communist Party of China is about several meanings for further strengthening urban planning and development control work See》It proposes, strives with 10 years or so time, making assembled architecture account for new building ratio and reaching 30%, assembled architecture is at me The development of state is being thus lifted to a unprecedented height.

In assembled arthitecutral structure, especially in prefabricated concrete structure, component connection is to ensure that structure is whole The key node of quality.Reinforced bar sleeve grouting connection is common bar connecting form, sleeve in prefabricated concrete structure It is in the milk and is connected as concealed work, the plumpness of strength cement-based grouting material directly influences prefabricated concrete structure in grout sleeve Quality and safety.But may be because personnel's lack of skill, misoperation in work progress or lack a sense of responsibility, cause to leak Slurry, running pulp phenomenon happen occasionally, and the appearance of this phenomenon has seriously affected grouting quality, the case where " filling discontented " occur, cause Fatal constructional deficiency.Therefore, the detection method of strength cement-based grouting material plumpness is building trade extensive concern in grout sleeve And urgent problem to be solved.

The detection method of the plumpness of sleeve grouting at present is broadly divided into inside member exterior nondestructive determination and grout sleeve The method of pre-buried sensor.Member exterior lossless detection method is mainly supercritical ultrasonics technology and Impact echo, due to reinforced bar sleeve Connection structure replaces for multilayer dielectricity, and detection environment is complicated, and strength cement-based grouting material is very thin in radial thickness, generally 5 ㎜~6 ㎜ causes existing engineering lossless detection method that can not effectively detect it.Publication No. is the China of CN105223344A Patent document proposes a kind of device and method of pre-buried sensor detection reinforced bar sleeve grouting plumpness：Damping vibration is sensed Device is embedded in the bottom of reinforced bar sleeve grout outlet, and sleeve grouting construction passes through after the completion or after grouting material solidification and detects sensing Whether the attenuation of device signal wave amplitude comes whether discriminating sensor is coated by grouting material, full to detect grouting material.But it should Method has the shortcomings that following three：(1) can only qualitative detection, can not to the turgor of grouting material carry out quantitative analysis, after being The result judgement of phase brings difficulty；(2) damping vibration sensor must be installed in place before grouting construction, and sensor is once embedded to Sleeve cannot be reused, if to all sleeve whole placement sensors in engineering, the later stage is taken a sample test at random, then Testing cost is excessively high, and each side is difficult to receive, if arranging a limited number of sensors at random before grouting construction, construction party according to Sensing station learns test point in advance, will be directed to known test point well construction, finally lose the meaning inspected by random samples at random Justice, and still buried security risk.(3) in progress when plastering construction, the sensor for stretching out wall part must be cut off, It is time-consuming and laborious to ensure the planarization of wall.
