Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings, but not as any limitation to the present invention.

[0014] A method of recording the depth of drilling and the number of hammer blows, such as figure 1 As shown, the method is to install a hammer sensor 2 on the drill rod 1, and the hammer 3 hits the hammer sensor 2 once, and the counter 4 located at the top of the drill rod just records once; a group of infrared rays are installed at intervals on the drill rod 1 Transmitter 7, when the probe 6 at the bottom of the drill rod 1 enters the ground to reach a depth of interval under the hammer 3, the infrared alarm 5 that is located at the top of the drill rod 1 immediately fails to receive the signal of the infrared emitter 7. Alarm, judge the depth of the probe 6 entering the ground by the alarm sound. The group of infrared emitters 7 is installed between the probe 6 and the impact sensor 2, one at an interval...

Abstract

The invention discloses a method for recording drilling depth and hammering times and a drilling device. The method is to install a hammering sensor on a drilling rod, and a heavy hammer Each When the hammer sensor is hit once, the counter set on the top of the drill rod will record once; a group of infrared emitters are installed at intervals on the drill rod, and when the probe at the bottom of the drill rod enters the ground and reaches an interval depth under the hammer, the set The infrared alarm on the top of the drill rod immediately alarms because it cannot receive the signal from the infrared emitter, and reminds the operator to record the number of hammer strikes at the penetration depth in time through the alarm sound; it avoids manually looking at the scale and counting the number of strikes Insufficient errors are prone to occur. The present invention is novel in concept, small in size, light in weight, compact in structure, convenient in transportation, fast in machine transfer, safe and reliable, convenient in maintenance, simple in operation and easy to master.

Description

technical field [0001] The invention relates to a method and a drilling device for recording drilling depth and hammering times, belonging to the technical field of geological exploration equipment. Background technique [0002] Many buildings have stone teeth or caves under the base, which eventually lead to uneven settlement of the entire building, resulting in cracks in the walls and roofs or more serious situations. The complexity of geological conditions and the diversity of building structures require that civil engineering technicians must be clear about the geological conditions under the foundation in engineering design. The drilling groove is an indispensable foundation detection work in building construction. Engineers and technicians can detect the concealed structure in the soil layer or roughly estimate the allowable bearing capacity of the soil layer according to the hammering number required for the drill rod to enter a certain depth of the foundation to be d...
