Problems solved by technology

However, the inventor found in the research process that the existing static penetrating equipment often deflects or even breaks the penetrating rod during the deep hole static penetrating test.
This is because the frictional force is too large or the penetration resistan

Embodiment Construction

[0017] The invention provides a static penetrometer, which can be applied to the field of deep hole static penetrative testing, and has good protection for the static penetrating probe rod, and can effectively avoid the static penetrating probe rod Deflection or even bending occurs due to excessive penetration resistance.

[0018] Embodiments of the present invention will be described in detail below in conjunction with the following drawings.

[0019] Specifically, such as figure 1 As shown, the present invention provides a static penetrating sounder, which includes a test platform 1, a plurality of slide rails 2 are arranged on the test platform 1, and a static penetrating probe rod is provided on each slide rail 2 3. Multiple static penetrating probe rods 3 are independent of each other. The upper end of the static penetration sounding probe rod 3 is connected with a ZIGBEE wireless communication module 4, and a wireless communication connection can be established with th...

Abstract

The invention relates to the technical field of geotechnical engineering prospecting, in particular to a static penetrometer. The static penetrometer can be applied to the field of deep hole static penetration tests. The condition that static sounding probing rods can be deviated and even bent when being subjected to excessively-high penetration resistance can be effectively avoided. The static penetrometer comprises a test platform. The test platform is provided with a plurality of sliding rails. Each sliding rail is provided with one static sounding probing rod in a penetrating mode, and thelower end of each static sounding probing rod is connected with a static sounding probe. The upper end of each static sounding probing rod is connected with a ZIGBEE wireless communication module, and each ZIGBEE wireless communication module is in wired connection with the corresponding static sounding probe. Each ZIGBEE wireless communication module is in wireless communication connection witha control terminal of the static penetrometer. A constraint sleeve is arranged on the periphery of each static sounding probing rod, and outer fixing tubes connected through threads are arranged on the peripheries of the corresponding constraint sleeves. The test platform is further provided with a penetrating oil cylinder used for driving and controlling the static sounding probing rods and the constraint sleeves.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering exploration, in particular to a static penetration sounder. Background technique [0002] The static penetration testing technology uses the power device to press the probe rod with the contact probe into the test soil layer, and tests the penetration resistance through the measurement system to determine the basic physical and mechanical properties of the rock and soil, such as: rock and soil deformation modulus, rock and soil Allowable carrying capacity, etc. However, the inventors found in the research process that the existing static penetrating equipment often deflects or even breaks the penetrating rod during the deep hole static penetrating test. This is because the frictional force is too large or the penetration resistance increases due to the hard rock and soil in the process of pressing down, so that the static penetrating probe rod cannot be well protected by the exce...
