An all-terrain static penetration counterforce support and installation method

Abstract

The invention discloses an all-terrain static penetrating force support and an installation method thereof, comprising an upper support plate, a circular opening A for placing a guide tube is opened in the center of the support plate, a metal bubble level is inlaid on a corner of the upper surface; The support plate has a circular opening B in its center, and two rivet holes are provided on each side, and the rivet bolts pass through the rivet holes to fix the lower support plate on the ground; the height adjustment mechanism includes four groups, The upper and lower ends of the four groups are installed on the four corners of the upper support plate and the lower support plate respectively, for adjusting the distance from the upper support plate to the lower support plate, and enabling the upper support plate to present a Any angle change of the lower support plate. The all-terrain static penetration counter force support provided by the present invention can be tightly attached to the surface of the stratum or other scenes, effectively realize the arrangement in different geotechnical engineering use scenarios, and greatly increase the applicability of the static penetration test. Multiple program requirements for geotechnical design construction weight.

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
