Description

Static sounding feeler lever and lowering device of protection tube

Technical Field

The utility model belongs to the field of geotechnical engineering tests, and particularly relates to a lowering device for a static sounding probe rod and a protection tube in a static sounding test.

Background

Static sounding test is an important in-situ test means in geotechnical engineering investigation, can obtain continuous soil layer test data, can visually judge whether the soil layer is good or bad, and is widely applied to engineering construction.

The conventional test method comprises the steps of firstly adopting a static penetrometer to penetrate a static probe rod connected with a static probe into a soil layer to a preset depth for testing, then pulling back the static probe rod, then adopting a static penetrometer method or a water flushing method to sequentially press a protection tube into the soil to the preset depth, then adopting the static penetrometer to lower the static probe rod connected with the static probe to the preset depth again, and continuing to penetrate for testing.

The traditional test method for lowering the protection tube has the following defects: 1. before the protection tube is put down, the static probe rod is required to be firstly inserted to complete the soil layer test work of a preset depth, then the protection tube is put down, and then the static probe rod is inserted again to carry out the test, so that the whole process is complicated and the duration is long; 2. when the water flushing method is adopted for the lower protection tube, a drilling machine is required to be arranged, the process is complicated, and in addition, a large amount of slurry is generated in the hole forming process of the drilling machine, so that the environment is polluted; 3. because the static probe needs to be pulled back, continuous testing cannot be realized, and testing at the same position cannot be guaranteed, so that the testing precision is influenced; 4. because the test data are collected twice, manual splicing is needed, and the test efficiency is influenced.

In a word, the traditional protection tube lowering mode in the static cone penetration test needs to test a soil layer in advance, and then the protection tube is lowered by adopting a static cone penetration tester method or a drilling machine water flushing method, so that the process is complicated, time and labor are consumed, and the produced slurry is easy to pollute the environment; in addition, the static probe is penetrated twice, so that the continuity and the same position cannot be ensured, and the data acquired twice needs to be spliced manually, so that the test accuracy and the test efficiency are influenced.
