Detachable pile foundation inspection device

Abstract

The invention relates to a detachable pile foundation hole inspection device, which is characterized in that it includes one or more hole inspection units, the hole inspection unit includes a main rod, a connecting block, a horizontal rod and a supporting rod, and the two end faces of the connecting block There is a threaded hole at each central position, the lower end of the main rod is screwed into the threaded hole on the upper end surface of the connecting block, there are four horizontal rods and each horizontal rod has the same length, and they are respectively threaded on the four sides of the connecting block In the threaded hole on the top, the outer ends of each horizontal rod form a circle with a certain diameter. There are four support rods, the lower ends of each support rod are detachably connected to the corresponding horizontal rods, and the upper ends of each support rod Removably attached to the main pole. All parts of this device can be disassembled, and the installation is very convenient. After installation, the size of the circle surrounded by the accessories on the four horizontal bars is the size of the pile foundation hole. If you need to measure the size of the pile hole, you only need to choose Or splicing out horizontal rods of corresponding length.

Description

technical field [0001] The invention relates to a diameter and verticality detection device for pile foundation holes of bridges and culverts, in particular to a detachable pile foundation hole detection device. Background technique [0002] During the construction of bored piles, the first thing to do is to drill holes. The quality of the drilled holes directly affects the quality of the pile foundation, so the requirements for the diameter and verticality of the holes are very high. [0003] There are many hole inspection instruments for pile foundations, but most of these instruments are expensive. For vertical bridge and culvert pile foundations that generally do not need to be divided into positions, there is no need to buy these expensive hole inspection devices, so many construction teams now start Use steel bars to make a steel cage with the same diameter as the aperture for simple measurement, but this kind of production is very time-consuming and wastes materials. ...

[0003] There are many hole inspection instruments for pile foundations, but most of these instruments are expensive. For vertical bridge and culvert pile foundations that generally do not need to be divided into positions, there is no need to buy these expensive hole inspection devices, so many construction teams now start Use steel bars to make a steel cage with the same diameter as the aperture for simple measurement, but this kind of production is very time-consuming and wastes materials. Although it can be used twice or multiple times, it is still quite troublesome to make and disassemble.
