Description

Device is visited to ground borer

Technical Field

The utility model relates to a device technical field is visited to the ground borer, especially relates to a device is visited to ground borer.

Background

The foundation drill rod detection is a soil layer detection construction process, standard diameter drill rods marked with scales are vertically hit into a foundation soil layer by using a hammer with a calibrated weight in a mechanical or manual mode, and the hidden structure condition in the soil layer is detected or the allowable bearing capacity of the soil layer is roughly estimated according to the number of the hammer required by the drill rods entering the foundation soil layer to be detected.

The foundation drill detector is a measuring instrument for detecting the depth of the foundation. Although the mechanical drill detector has high accuracy, the equipment is large and high in cost. Although the manual drill rod detection device has low precision, the device is simple and convenient and is easy to carry. The manual drill rod detection device is composed of a rack rod which is vertically fixed on the ground, and a heavy hammer acts on a steel drill rod and repeatedly strikes to enable the steel drill rod to vertically enter a foundation. In actual operation, when a weak subjacent layer exists, the steel chisel sinks obviously, and human factors can be completely ignored, so that the manual chisel detection is still widely applied. But a drill rod poor stability needs artifical support during the measurement, causes the manpower extravagant, and artifical support straightness that hangs down is not master well, probably causes the weight angle to take place the skew, influences measurement accuracy.
