Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, the utility model discloses a kind of plug-in type reinforcing bar preformed hole grouting compactness detection device, comprises computer 1, signal amplifier 2, preformed hole 3, sensor 4, hand hammer 5, reinforcing bar 6. In described preformed hole 3, be provided with reinforcing bar 6,3 grouting of reinforcing bar 6 and preformed hole are connected to form preformed hole slurry anchor connector, and this preformed hole slurry anchor connector can have various ways, but which kind of mode no matter all will realize reinforcing bar 6 and be connected with the firm of preformed hole 3.
A kind of plug-in type reinforcing bar preformed hole grouting compactness detection device, its detecting step is as follows:
S1: reinforcing bar is put into preformed hole, to being in the milk in preformed hole, form preformed hole slurry anchor;
S2: connect computer, signal amplifier, sensor, host parameter is set;
S3: sensor is attached on the surface of detected preformed hole body of wall;
S4: shake and be detected the surface of preformed hole body of wall with little hammering;
S5: sensor receives reflected signal;
S6: signal amplifier amplifies to the received signal and signal data is stored in instrument;
S7: computer read signal data are also carried out Spectrum Analysis, and analysis result and control group are compared, and draw this preformed hole grouting compaction rate.
Further, preferentially select sensor to be placed on and hit the 15cm around that shakes a little.
After preformed hole carries out grouting construction, ensure that slurry setting and harden intensity at least reaches 75% of design strength. Implemented by above-mentioned steps, can be judged by the characteristic of reflected signal the closely knit situation of the inner grouting of preformed hole. According to having or not and the length of reflection interval of the reflected signal in preformed hole, can judge the inner grouting of preformed hole defect situation.
As shown in Figure 2 and Figure 3, be the utility model ripple propagation condition comparison diagram in the whether closely knit two kinds of situations of grouting material. Fig. 2 is grouting material wave propagation schematic diagram when closely knit, Fig. 3 is defectiveness wave propagation schematic diagram, in the time there is defect in grouting material, the ripple of exciting can produce reflection by a part of ripple at fault location, another part ripple is walked around defect reflection also can produce the reflection that lags behind, and fault location is longer with respect to the reflection interval at closely knit place.
Fig. 4 adopts the ripple that the utility model device and test method obtain to carry out the isogram after spectrum analysis in above-mentioned two situations, the power of the altimeter oscillography energy of isogram medium wave peak, abscissa represents reflection interval, Ch.1 is oscillogram in the closely knit situation of grouting material, Ch.2 is oscillogram in the closely knit defectiveness situation of grouting material, from comparison diagram, can find out, when defectiveness, ripple is propagated disorderly and hysteresis reflex. Show by test, the utility model device and test method can judge preformed hole grouting packing situation.
Above-described the utility model embodiment, does not form the restriction to the utility model protection domain. Any amendment of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present utility model.
