Description

Device for measuring levelness of core drilling detection equipment in real time

Technical Field

The utility model relates to a bore core detection area, the more specifically device of real-time measurement brill core check out test set levelness that says so.

Background

The cast-in-place concrete pile is widely applied to building engineering, and the quality of the cast-in-place concrete pile can be detected by a low-strain method, an ultrasonic detection method, a static load method, a core drilling method and other detection methods. The core drilling method can detect the pile length, the pile body concrete strength, the pile bottom sediment thickness and the pile body integrity of the cast-in-place pile, and judges or identifies the pile end bearing layer rock-soil property, is a method for directly and reliably detecting the pile body quality of the concrete cast-in-place pile, and has irreplaceable advantages compared with other detection methods. However, in the core drilling detection process, due to the influence of factors such as the technical level of detection personnel and improper instrument operation, the condition that the core drilling detection drill hole deviates from the pile body and cannot be detected to the position to be detected is often caused, so that the quality of the pile body at the middle lower part of the most important pile, the sediment at the bottom of the pile and the bearing stratum cannot be judged, at the moment, other detection methods are required to be adopted to continuously detect to evaluate the quality of the pile body, the condition can cause delay of construction period and increase of test cost, and the economical efficiency and the application value of the core drilling method detection are reduced.

The deviation of the core drilling hole out of the pile body is caused by the fact that the drill rod is not perpendicular to the cross section of the pile body due to the inclination of core drilling equipment, and mainly caused by the problems that the installation of drilling equipment is unstable, a base is not horizontal, the center of a vertical shaft of a drilling machine, the center of a head sheave and the center of an orifice of the drilling machine are not on the same plumb line, and the like. The detection personnel can adjust the drilling machine equipment to the levelness meeting the standard requirements when beginning to detect, but the reason such as because vibrations influence or base foundation subsides can lead to the detection equipment of adjusting to deviate from original position in the drilling process to lead to the drilling machine slope, shift and then influence the drilling rod straightness that hangs down, lead to the drilling skew. The control of the levelness of a drilling machine and the verticality of a drill rod is a key link for detecting whether the cast-in-place pile is successful or not by a core drilling method.

A leveling rod is usually adopted to measure the levelness of the drilling machine in the core drilling detection, and the method is convenient and accurate. The perpendicularity deviation of the drill core hole is required to be less than or equal to 0.5% (namely the ratio of the horizontal offset of the drilling machine to the total drilling amount) specified by the pile foundation detection standard, the value cannot be judged through manual visual inspection, a detector usually measures the levelness of the drilling machine through a leveling rod after obvious deviation appears in actual detection, even if the inclination of a drill rod is accurately obtained to exceed the standard requirement, the perpendicularity of the drill rod is adjusted by adjusting the levelness of the drilling machine, and the core drilling detection is relatively late and is inevitable to deviate.

In conclusion, if the verticality of the drill rod can be calculated by detecting the levelness of the drill in real time, the drill is stably readjusted before the verticality deviation exceeds the range, the deviation of the drill hole can be avoided, and the success of the detection work of the drill core can be ensured.
