Description
Technical Field
The utility model belongs to the technical field of the engineering detects technique and specifically relates to an automatic open bored concrete pile aperture detector of leg.
Background
In the technical field of engineering detection, a caliper is often used for detecting the drilling quality of a cast-in-place pile, and a common caliper has three or four arms, and the tail end of the caliper is stretched to be tightly attached to a well wall under the action of a spring. Along with the change of the well diameter, the tail end of the arm is opened or closed, and meanwhile, the potentiometer sliding arm is driven to move. The change in the hole diameter then becomes a change in resistance. When the potentiometer is powered through the cable, the changing potential difference between the resistors reflects the change in the hole diameter. The ground recording part records the potential difference change which passes through the hole diameter gauge in advance, and the change is the hole diameter.
When the conventional caliper is used, a measuring leg of the caliper is closed, an open leg disc is sleeved on the measuring leg disc and is put into a well hole (a cable is hung on a pulley through a small pulley), a winch is started, the caliper is put down, the caliper stops when a special mark on the cable is put down to the beginning of drilling depth, the depth display value is preset to be 5.00m, the depth of a stop hole is preset to be 3.00m, and a mark rod is fixed on a ground projection point at a certain depth mark on the cable to serve as a depth standard point. The depth display value will then directly indicate the position of the gauge in the hole. And clicking a button of an aperture measurement window for starting to measure down, starting the winch for starting to measure down, and displaying the change of the depth at the moment. The caliper is lowered until the caliper reaches the bottom of the hole, at which time the cable will relax. And (5) tightening the cable, and taking the actual hole depth value. The cable is loosened, the cable is lifted up manually and quickly at the wellhead, the leg opening disc is separated from the measuring legs due to the resistance of slurry, and the measuring legs automatically spring open and cling to the hole wall. Since the measurement leg bound state aperture value is displayed in the aperture text box before the measurement leg is not opened, the winch is started to hoist the cable, and the measurement aperture value larger than the bound state aperture value is displayed in the aperture text box, indicating that the measurement leg is opened (note that when the mud in the bottom of the hole is too thick, the measurement leg cannot expand to the hole wall, and the measurement aperture value may be smaller than the design value). And (5) tightening the cable, and measuring the depth change of the instrument by using a steel tape (correcting the change of the depth of the instrument after the binding device is removed, and determining the starting depth).
Conventional caliper tools suffer from the following disadvantages:
(1) in the aperture measuring process, a leg opening disc is sleeved on a measuring leg of the caliper, and if the leg opening disc is not touched with a hole wall or the speed is not uniform in the lower measuring process, the leg opening disc is easy to fall off, so that the umbrella leg of the caliper is unfolded, and the caliper needs to be lifted up for retesting.
(2) The cable is lifted up manually and quickly (shaking vigorously), the leg opening disc is separated from the measuring leg by using the resistance of slurry, and the leg opening mode firstly has the possibility of damaging the cable and secondly has the disadvantages of not being capable of effectively opening the leg and even needing to shake for many times, so that the use is inconvenient.
