Problems solved by technology

However, in its technical solution, since the geophone is arranged on the side of the drill bit, and the drill bit vibrates violently during the drilling process, the geophone may be damaged during the drilling process; at the same time, each time the drill bit reaches a measurement position, it needs Stop drilling and continue drilling after geophone measurement. The detection process is complicated and the drilling angle of the probe may deviate at different measurement positions, which will affect the measurement results of the geophone

Embodiment Construction

[0016] In order to illustrate the technical solution of the present invention more clearly, the following examples will be used to briefly introduce the present invention. Obviously, what is described below is only the embodiments of the present invention. On the premise of creative work, other technical solutions can also be obtained according to these embodiments, which also belong to the disclosure scope of the present invention.

[0017] The survey drill bit of the embodiment of the present invention, see figure 1 , including a tapered end 10 , a drill rod 20 , a first drill body 30 , a second drill body 40 and a strain gauge 50 .

[0018] The tapered end 10 is located at the bottommost portion of the exploration drill bit for drilling into soil formations. The drill pipe 20 is fixed at the central axis of the tapered end 10 and connected to the drilling rig to drive the tapered end 10 to detect near the pile foundation.

[0019] The first drill body 30 includes a lower ...

Abstract

The invention provides a survey drill bit and a pile foundation detection device which are used for collecting soil layer information and detection device quality. After the exploring position is reached during hole drilling, a wave detector is placed at the specified soil layer depth, excitation wave signals generated by a pile foundation are directly detected through the wave detector, thus a time-depth waveform diagram is generated, and the quality of the pile foundation is determined.

Description

technical field [0001] The invention relates to pile foundation detection technology, in particular to a survey drill bit and a pile foundation detection device. Background technique [0002] With the vigorous development of engineering construction in our country, a large number of pile foundations are used in high-rise buildings, bridges, roads, ports, wharves and other projects. Pile foundations have become the most important type of foundation in engineering construction in our country. Accounting for more than 1 / 4 of the total cost of civil engineering, the quality of pile foundation plays a decisive role in the quality of engineering construction. [0003] The construction process of the pile foundation project is complex, and it is easily affected by various factors such as construction personnel, mechanical equipment, geology, environment, etc., resulting in quality problems, which will affect the bearing capacity of the pile foundation and the stability of the super...
