Rapid sampling device for water stable layer

Abstract

The invention provides a rapid sampling device for a water stable layer. The rapid sampling device comprises: a base plate, wherein a circular sampling hole is formed in the center of the base plate; and a handheld electric pick and a pick shovel, wherein the pick shovel is installed on the handheld electric pick, a shovel head is arranged at the lower end of the pick shovel, a circular arc matched with the edge of the sampling hole is formed in the outer side wall of the shovel head, and a sampling notch is formed in the inner side wall of the shovel head. According to the invention, pedal plates are additionally arranged on the two sides of the base plate to serve as pedal fixing handrails and matched with foot nails of the base plate, so that the position of a test pit is fixed, and the base plate is prevented from deforming and moving in the punching process and affecting the test; and the handheld electric pick is used as a power source, the pick shovel is improved, the original pick shovel is manufactured by forging a steel bar, is irregular in the shape, and is low in chiseling efficiency, the original pick shovel is improved into an arc crescent shape, and the pick shovel is installed on the handheld electric pick for chiseling, so that the original manual chiseling is replaced.

Description

technical field [0001] The invention relates to a rapid sampling device for a water stable layer. Background technique [0002] In the process of water stabilization construction, the frequency of compaction detection is relatively high, and the commonly used detection method is the sand filling method. Sand filling method test steps: (1) Carry out a compaction test on the same material to obtain the maximum dry density and optimum moisture content. (2) For the test site, select a flat surface and clean it. (3) Put the substrate on the test site, put the sand filling cylinder containing a certain amount of sand on the round hole in the middle of the substrate, turn on the switch of the sand filling cylinder, let the sand flow into the middle hole of the substrate, until the sand storage cylinder Turn off the switch when the sand inside is no longer flowing down. Remove the sand filling cylinder, and weigh the quality of the sand in the cylinder. (4) Take away the substra...

Problems solved by technology

[0003] During the test and detection process, manual drilling is the most critical and labor-intensive and time-consuming process in the entire test and detection. After investigation, it is found that manual drilling is not only inefficient, time-consuming and laborious, but also has a relatively large impact on test data due to human factors. Big
