Description
Technical Field
The utility model belongs to the technical field of pile foundation detection, and particularly relates to an intelligent monitoring device for bored pile hole-forming quality based on ultrasonic waves.
Background
The pile foundation is a foundation form with high bearing capacity and wide application range. The pile foundation is composed of a plurality of piles (called pile groups) buried in a foundation and a pile platform (called bearing platform) which combines the pile groups to work together. The pile foundation has the function of transferring load to a soil layer with good bearing performance deeper underground so as to meet the requirements of bearing capacity and settlement. The pile foundation has high bearing capacity, can bear vertical load and horizontal load, can resist uplift load and can bear vibration load, and is a deep foundation form which is most widely applied. The piles are classified into cast-in-place piles and precast piles according to the construction process, and the piles formed by drilling holes by mechanical rotation and then pouring concrete or reinforced concrete into the holes are called cast-in-place piles. According to the characteristics of the pore-forming process, the method can be divided into three categories of forward circulation rotary drilling, reverse circulation rotary drilling and non-circulation spiral drilling, and has the application range and the advantages and the disadvantages of the method.
But the underground pore-forming of the cast-in-place pile has a plurality of influence factors, and the engineering quality is difficult to control. Among them, the excessive thickness of the sediment at the bottom of the hole is one of the common reasons influencing the bearing capacity of the pile body, and the quality accident is possibly caused. Therefore, the monitoring of the thickness of the sediment at the bottom of the hole is particularly important in the construction process of the slurry retaining wall cast-in-situ bored pile.
Ultrasonic foundation pile pore-forming detects, concrete drilling bored concrete pile pore-forming ultrasonic detection's rationale: the winch of the instrument is arranged on a hole, the ultrasonic transmitting and receiving probe is aligned to the center of a drill hole, the pulse signal generator sends a series of electric pulses to be applied to the piezoelectric body of the transmitting transducer in the process that the probe descends along the center line of the drill hole, the piezoelectric body converts the signals into ultrasonic pulses and transmits the ultrasonic pulses, and the ultrasonic pulses penetrate through the mud and the side wall of the drill hole, are partially reflected back to be received by the receiver and then are converted into electric signals to be output to the operation instrument. And (3) according to the intensity of the reflected signal and the reflection time difference, the operation instrument prints a hole wall curve on printing paper in real time. And the drilling quality can be visually judged according to the image.
But traditional ultrasonic wave pore-forming detector is in actual operation, hardly guarantees along the perpendicular decline of drilling center, and same swing, striking and the slope problem that takes place directly influences the measured data accuracy. In order to enable the ultrasonic pore-forming detector to vertically descend along the center of a drill hole, a guide wheel is additionally arranged on the outer side of the ultrasonic pore-forming detector in the existing equipment, and the guide wheel descends along the inner wall of a pile hole to provide guide for the ultrasonic pore-forming detector. Because stake downthehole wall is not the smooth surface, and there is the scheduling problem that collapses in stake downthehole wall part district in the stake, and the leading wheel blocks easily in the stake is downthehole, leads to the unable decline of ultrasonic wave pore-forming detector.
