Detailed description of the invention
The present invention is further illustrated below by way of specific embodiment.
As shown in Figure 1, a kind of cast-in-place pile concrete interface identifies and super filling loosening apparatus, its involving vibrations perflectometer 1, data wire, outer sheath tube 2, back wave receiver 3 and gauge tap, vibration perflectometer 1, data wire, back wave receiver 3 are connected with the gauge tap successively signal of telecommunication, it is outer to play a protective role that outer sheath tube 2 is placed on data wire, and its two ends are tightly connected with vibration perflectometer 1 and back wave receiver 3 respectively; Described vibration perflectometer 1 comprises shell and as the vibrating motor in shell, described back wave receiver 3 comprises signal processing chip and display device, the data that vibration perflectometer 1 produces are passed to signal processing chip place by data wire, the signal of collection is converted to data according to initialize program and exports through display device by signal processing chip.
Described device carries out the recognition methods at cast-in-place pile concrete interface: comprise the steps:
Step 1, after castinplace pile secondary pile hole cleaning, along conduit, vibration perflectometer is put at the bottom of priming concrete pile hole between conduit and filling pile cage of reinforcement, follow concrete progress of building and promote vibration perflectometer, open gauge tap and back wave receiver, make vibration perflectometer adopt low Oscillation Amplitude promote in stake holes or fall, the vibration wave changes in amplitude produced for concrete and mud by vibration concretely builds interface to identify;
After step 2, cast-in-place pile concrete are built, promote vibration perflectometer and fill with height centre position to castinplace pile is super, the Oscillation Amplitude of vibration perflectometer is regulated to reach high amplitude vibrational state by gauge tap and back wave receiver, segregation effect is reached to carry out super shaking to the concrete in super filling height, reduce super concrete strength of filling with in height, saved and cut concrete cost and duration;
Step 3, extract vibration perflectometer, be shifted next root castinplace pile.
The low Oscillation Amplitude of above-mentioned vibration perflectometer refers to that vibration frequency is 15 ~ 30HZ, and the high Oscillation Amplitude of vibration perflectometer refers to that vibration frequency is more than 150HZ.
The Cleaning Principle at this device concreting interface is: vibration perflectometer 1 is similar to concrete vibration bar, vibrating motor is provided with in it, the vibration wave produced when utilizing vibration perflectometer 1 to vibrate is to detect concrete casting interface, because concrete density is that the twice of mud is many, under same vibration, the vibration wave amplitude length that both produce has obvious difference, the vibration output voltage of perflectometer 1 and the Oscillation Amplitude linear approximate relationship of ambient medium.When vibrating perflectometer 1 and being in layer of concrete, the energy sponging more greatly vibration wave due to concrete density is comparatively large, and the amplitude of vibration perflectometer 1 is less, and the voltage of output is less; Then contrary when vibrating when perflectometer 1 is in mud layer, the voltage that vibration perflectometer 1 exports is larger.The voltage data that this perflectometer 1 exports and vibration back wave are delivered to back wave receiver 3 by the holding wire in outer sheath tube 2, and the signal processing chip in back wave receiver 3 identifies concrete interface residing for current vibration perflectometer according to the different wave received and feeds back on display device.So, for the conduit depth of burying of concreting provides Data support, also for supplement amount during last concrete deficiency provides data accurately, avoid concrete waste or super filling phenomenon.
As shown in Figure 2, the circuit theory of this equipment is: by arranging suitable reference voltage and perflectometer output voltage ratio of components comparatively amplifying circuit, as shown in the figure, Vout is the magnitude of voltage of perflectometer output voltage after putting, and is compared by comparator with suitable reference voltage V ref.When Vout is greater than reference voltage V ref, present position amplitude is comparatively large, illustrates that perflectometer is in mud layer, and comparator exports high level, and the DS2 lamp of gauge tap is bright, phase inverter output low level, and the DS1 lamp of gauge tap goes out; When Vout is less than reference voltage V ref, perflectometer present position is layer of concrete, comparator output low level, and phase inverter exports high level, and the DS1 lamp of gauge tap is bright, DS2 lamp goes out.The position residing for perflectometer can be judged by indicator lamp DS1 and DS2 on gauge tap, the interface location of concrete and mud layer can be known according to the length of outer sheath tube.
The concrete principle of the loose super filling of this device is: vibration perflectometer 1 Oscillation Amplitude divides two grades, and (low amplitude is vibrated: vibration frequency 15 ~ 30HZ, high-amplitude are vibrated: more than vibration frequency 150HZ), low amplitude is used to vibrate rank when identifying concrete and slurry interface, in order to avoid produce segregation phenomenon to vibratory concrete, it is closely knit that the simultaneously vibration of low amplitude is also conducive to that cast-in-place pile concrete builds; When concreting completes, when vibrating perflectometer 1 and being promoted to super filling in altitude range, by regulation control switch and back wave receiver 3, strengthen vibration perflectometer 1 Oscillation Amplitude and reach high-amplitude vibration rank (during high-amplitude vibration rank, the oscillating region of vibration perflectometer 1 is the stake footpath of a times), thus in height, large frequency is carried out to concrete excessively vibrate concrete super filling, reach super effect of filling with the concrete disintegration of altitude range, its intensity is reduced, for after follow-up castinplace pile excavation, cutting of stake top laitance provides convenient with loose concrete.
