All-terrain static sounding counterforce bracket and mounting method

Abstract

The invention discloses an all-terrain static sounding counterforce bracket and a mounting method. The all-terrain static sounding counterforce bracket comprises an upper supporting plate, a lower supporting plate and four groups of height adjusting mechanisms, wherein the a round opening hole A for placing a guide pipe is formed in the center of the upper supporting plate; a metal bubble level gauge is inlaid in one corner of the upper surface of the upper supporting plate; a round opening hole B is formed in the center of the lower supporting plate; two rivet holes are formed in each side ofthe lower supporting plate; rivet bolts are fixed on the ground through the lower supporting plate; the upper ends and the lower ends of the four groups of height adjusting mechanisms are arranged onfour corners of the upper supporting plate and the lower supporting plate correspondingly; the four groups of height adjusting mechanisms are used for adjusting the distance from the upper supportingplate to the lower supporting plate and enabling the upper supporting plate to take on any angle change with the lower supporting plate. The all-terrain static sounding counterforce bracket providedby the invention can be in tight fit with the surface of the ground or other scenes, so that arrangement in different geotechnical engineering use scenes is effectively realized, the applicability ofstatic sounding is greatly enhanced, and various schemes are provided for geotechnical design construction.

Description

technical field [0001] The invention relates to a static sounding counterforce support, in particular to a static sounding counterforce support suitable for various terrains and an installation method. Background technique [0002] Static CPT refers to using a pressure device to press a penetrating rod with a probe into the test soil layer. By measuring the penetration resistance, cone head resistance and side wall friction resistance of the soil in the measurement system, some basic properties of the soil can be determined. Physical and mechanical properties, such as soil deformation modulus, soil allowable bearing capacity, etc. Static CPT is mainly applicable to cohesive soil, silty soil and sandy soil. For various water conservancy projects, industrial and civil construction projects, and highway and bridge projects in the lower reaches of the Yellow River, static sounding is suitable for various soil layers within 50m below the ground, especially for complex sites with...

Problems solved by technology

Most of the former are directly installed on the loading transport vehicle. The advantage is that it is convenient for the on-site transportation of the static penetration testing equipment, and the tires or crawler belts of the vehicle in contact with the ground are used to stabilize the probe rod. The ground is arc or inclined, and the probe rod is in the direction of the ground, which is not conducive to the test requirements; the latter is flexible in layout, and the counterforce device is fixed on the ground through a spiral ground anchor, but due to its single industrial design, it will also Affected by flatness or slope
