Description

Technical Field

[0001] The present invention relates to the technical field of geotechnical engineering investigation, and in particular to a static penetration device and a detection method that can be used in special scenarios. Background Art

[0002] Static penetration testers are widely used in geotechnical engineering surveys to test the physical and mechanical properties of strata. They can be used as an in-situ test method or as an exploration point. Static penetration testers use static force to press the probe downward into the stratum soil at a certain rate. By detecting and recording the penetration resistance and changes of the probe, the properties of the engineering soil strata can be mastered. The test results can be used to divide strata, determine the bearing capacity, compressibility index, plastic state of foundation soil, and evaluate geotechnical engineering properties such as earthquake liquefaction trend.

[0003] According to the pressurization method, static penetration instruments can be divided into three types: hand-cranked, mechanical and hydraulic. At present, engineering and technical personnel generally use hydraulic type, which has a larger penetration force. The reaction force forms of static penetration include using anchors as reaction force, using heavy objects as reaction force, and using the vehicle's own weight as reaction force. The penetration rod is usually a seamless steel pipe with an outer diameter of 32 to 42 mm, and each penetration rod is about 1 meter long. Static penetration can be applied to different strata such as clay, silt, sand, fill, and soil layers with a small amount of gravel. In particular, it is more accurate in judging soft soil and is widely used in sites with more soft soil.

[0004] However, the currently commonly used static penetration testers in engineering are still limited in the applicable terrain scenarios. Because the probe rod of the traditional static penetration tester is located in the center of the instrument, the instrument and the probe must be on the same flat site at the same time to stably carry out the test. In the actual engineering survey process, especially in sites with many steep terrains and ponds and ditches, the exploration points are often distributed in the steep slopes or under the slopes, and in the water near the banks of ponds and ditches. In these cases, static penetration test and drilling cannot be carried out, and exploration must be carried out after the site is leveled. This leads to the untimely acquisition of geological data, the inability to accurately determine the engineering geological conditions in a timely manner, and the delay of the project progress. If the site is leveled repeatedly, it will lead to increased engineering volume, waste of time, manpower, and funds. Summary of the invention

The static penetration device that can be used in special scenarios according to claim 1 is characterized in that: It also comprises an anchor (17), wherein the anchor (17) is used to anchor the anchor nail (16) passing through the ground anchor (14) into the soil layer on the top of the bank slope.

8. The static penetration device that can be used in special scenarios according to claim 7 is characterized in that: The ground anchor (14) is a triangular steel, and a counterweight is provided at a corner of the ground anchor (14) away from the telescopic clamping rod assembly (5).

9. The static penetration test equipment that can be used in special scenarios according to any one of claims 1 to 8, characterized in that: It also comprises a static probe controller (4), wherein the static probe controller (4) is electrically connected to the probe (1) via a line (3) passing through the probe rod (2), and the static probe controller (4) is electrically connected to the driving mechanism (10).

10. A detection method using the static penetration test equipment that can be used in special scenarios according to any one of claims 1 to 9, comprising the following steps: Anchoring a nail (16) passing through a ground anchor (14) into an underground soil layer at a flattened site on a bank slope top near a target detection point using an anchoring device (17), and adjusting the ground anchor (14) to a horizontal level according to a bubble level (18) provided on the ground anchor (14); A first probe rod (2) with a probe (1) mounted on the lower end is inserted into a first clamping rod groove (6) of a retractable clamping rod assembly (5), and a first clamping valve is controlled by a first clamping switch (7) to clamp the first probe rod (2); The telescopic clamping rod assembly (5) is controlled to extend toward the offshore side by a first horizontal telescopic switch (8), and the probe is adjusted to above the target detection point; Inserting a second probe rod (2) into a second clamping rod groove (24) at the other end of the horizontal telescopic rod, and controlling a second clamping valve (27) through a second clamping switch (22) to clamp the second probe rod (2); The horizontal telescopic rod is controlled to move toward the offshore side by a second horizontal telescopic switch (21), and the second probe rod (2) is controlled to move above the first probe rod (2). The vertical telescopic rod is controlled to descend by a vertical telescopic switch (20), and the ring motor (26) is controlled to rotate the second probe rod (2) in cooperation with the rod slot rotation switch (23), so that the lower end of the second probe rod (2) is threadedly connected to the upper end of the first probe rod (2); The second pipe clamp switch (22) is used to control the second pipe clamp valve (27) to loosen the second probe rod (2), and the second horizontal telescopic switch (21) is used to control the horizontal telescopic rod to retract toward the top of the bank slope, and this is repeated until all the probe rods (2) are installed; The static probe controller (4) controls the driving mechanism (10) to drive the retractable clamping rod assembly (5) and the probe rod (2) to descend until the first probe rod (2) descends to a set depth, and the probe (1) collects penetration resistance data at the same time; After the detection is completed, the static probe controller (4) is used to control the driving mechanism (10) to drive the retractable clamping rod assembly (5) to move in the reverse direction, and the probe rod (2) is disassembled and recovered, thereby retrieving the entire probe device.
