Embodiment Construction

[0019] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0020] like figure 1 As shown, this embodiment provides a multifunctional miniature static penetrating probe rod, which is composed of three parts: a probe 1 , a connecting rod 2 and a connecting top plate 3 .

[0021] According to different penetration depths, different soil conditions and different structures, the probe 1 is set in three forms in total. Grooves are processed on the top surfaces of the three types of probes 1, and threads are tapped in the grooves for placing and connecting miniature tension and pressure sensors.

[0022] like figure 2 As shown, the first type of probe 1 is a conventional conical probe, and the angle of the cone head of the conical probe is 60°. The conical probe is mainly aimed at indoor model tests in sandy soil...

Abstract

The invention belongs to the field of geotechnical engineering foundation reconnaissance and discloses a multifunctional micro static feeler lever. The multifunctional micro static feeler lever comprises a probe, a connecting rod and a connecting top plate which are connected from bottom to top in sequence. The probe is a conical probe or a cylindrical probe or an anti-drag ring probe, wherein theanti-drag ring probe comprises an anti-drag ring, and the anti-drag ring is in the shape of a circular truncated cone with the bottom surface diameter smaller than the top surface diameter. The connecting rod is connected with the probe through a micro tension and pressure sensor, the connecting rod and the connecting top plate are connected through a micro tension and pressure sensor, and the probe, the connecting rod and the connecting top plate do not make contact directly. According to the multifunctional micro static feeler lever, the most proper probe can be selected according to different soil properties and interaction between structures and soil bodies, the end resistance and the frictional resistance are detected at the same time in the whole penetration process, the levelness of the connecting top plate can be further adjusted precisely, and accordingly, the different soil properties and stress variation situations of the device in the mounting process of different structures can be more clearly known.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering foundation investigation, and in particular relates to a multifunctional miniature static penetrating probe rod under different soil conditions and different structural forms. Background technique [0002] In order to meet the development requirements of human society, more and more civil engineering projects are being constructed all over the world. In order to accurately judge the reliability of the foundation design, the preliminary survey work is very important, and the static penetration test is one of the most commonly used survey methods in the survey work. However, due to the complexity of the real situation, conventional static sounding equipment often cannot accurately reflect the real soil conditions on the site, as well as the interaction between soil and structures, especially for offshore wind power projects. Accurate survey results are crucial to The safety construction of t...
