In roadbed dirt work progress, it is the most important thing of quality control to the detection of degree of compaction, if compaction detect value is defective, then will affect the construction quality of road surface entirety to a great extent, and will road surface be made at short notice to occur structural destruction, there is the disease such as map cracking and hole groove in road table.
In the roadbed dirt work progress of present stage, usually all adopt the sand replacement method provided in " highway subgrade road surface on-the-spot test code " (JTGE60-2008) to carry out Field Compactness detection to the detection of degree of compaction.So-called sand replacement method detects degree of compaction, namely by the standard sand of known apparent density come equal-volume displacement compacting complete after soil sample, thus the actual dry density in the scene calculating dirt, and compare with the standard maximum dry density that laboratory test obtains, obtain actual degree of compaction.
In actual mechanical process, owing to lacking boring extracting soil equipment supporting specially, on the one hand, the cutter of testing pits is got and is wasted time and energy, and needs at least two people to take turns operation, on the other hand, what artificial chisel was got test pits, and inwall is sufficiently oily, also have impact on the accurate reliability of result of the test to a certain extent.
Summary of the invention
The purpose of this utility model is to provide a kind of sand replacement method to detect the Special digging aperture apparatus of degree of compaction.
In order to realize above object, the utility model provides the Special digging aperture apparatus that a kind of sand replacement method detects grey soil compaction, and it comprises several drill rods, cutting ring, the steel plate of circular in cross-section, handle, described cutting ring down-bite jaw, cutting ring upper end is fixedly connected with bottom steel plate, several drill rods described are all welded on bottom steel plate, in vertically evenly gathering in cutting ring, and in cone-shaped bottom drill rod, ring screw is carved with on surface, and described handle is located on upper surface of steel plate.
Further scheme is, also comprises protection sleeve, and described protection sleeve upper end is provided with opening; lower end is provided with bottom; protection sleeve internal diameter is slightly larger than steel plate diameter, and protection sleeve is enclosed within outside steel plate and cutting ring, and protection sleeve upper end is provided with 3-4 fastener and can be flexibly connected with steel plate 3.
Further scheme is, also comprises protection sleeve, and described protection sleeve upper end is provided with opening; lower end is provided with bottom; protection sleeve external diameter is identical with steel plate diameter, and protection sleeve is enclosed within outside cutting ring, and protection sleeve upper end is provided with 3-4 fastener and can be flexibly connected with steel plate.
In actual mechanical process, the Special digging aperture apparatus provided by the utility model is directly placed on the dirt that need carry out detecting or the steady layer of water on the surface, by hammering top layer disk, downward active force is applied to equipment, come to apply active force to the soil body by the drill rod of device bottom and cutting ring.
The design of cutting ring can make to cut a hole the inwall of testing pits got round and smooth, thus improve the precision of testing inspection.
The design of drill rod can make equipment under same hammer force effect, reaches large as far as possible disturbance and destroys, whole borehole process is saved time, laborsaving to the interior soil body of testing pits.
The utility model has following beneficial effect: structure is simple, and reasonable in design, operating efficiency is high, easy to operate, and hole quality is good, detects data reliable, accurate, effectively can save the overall operating time.
