Static sounding device and static sounding method

Abstract

The invention discloses a static sounding device and a static sounding method, and relates to the technical field of geotechnical investigation. The static sounding device comprises a sounding machine body and a supporting frame, wherein the sounding machine body is arranged at the top end of the supporting frame, the sounding machine body comprises a sounding feeler lever, a sounding probe is installed at the bottom end of the sounding feeler lever, at least three inserting rods are arranged at the bottom end of the supporting frame at intervals, supporting discs sleeve the inserting rods in a threaded mode, connecting sleeves slidably sleeve the outsides of the inserting rods, inserting plates are hinged to the outer side walls of the connecting sleeves, bearing plates are hinged to the bottom end of the supporting frame, and the inserting plates are in sliding fit with the bearing plates. According to the static sounding device, the inserting rods are inserted into foundation soil, the position of a supporting disc on the inserting rods can be adjusted by rotating the supporting disc, and the bottom end of the supporting disc abuts against the surface of the foundation soil to support the supporting frame, so that the supporting frame is kept in the horizontal state, the sounding feeler lever is vertically inserted into the foundation soil, and the accuracy of static surveying of the foundation soil is improved.

Description

technical field [0001] The present application relates to the technical field of geotechnical engineering exploration, in particular to a static penetration testing device and a static penetration testing method. Background technique [0002] Static CPT refers to using the pressure device to press the penetrating rod with the probe into the test soil layer, and measure the penetration resistance, cone head resistance and side wall friction resistance by pressing the conical probe into the soil at a uniform speed at a certain rate , so that some basic physical and mechanical properties of the soil can be determined, such as the deformation modulus of the soil, the allowable bearing capacity of the soil, etc. [0003] The Chinese utility model patent with the authorized announcement number CN207469211U in the related technology discloses a static penetrating probe device, which includes a host and a supporting beam. The host is fixedly arranged on the top of the supporting bea...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that it is difficult to ensure the flatness of the ground of the foundation soil to be surveyed when performing penetration testing on the foundation soil, which will easily lead to the inclination of the static penetration testing device, and then there will be static force inaccuracy defect
