Preferably, the radian of the blade is 1/3-1 pi.
(1) During field test, the height and weight of the sand surface in the sand storage cylinder are consistent with those of the indoor calibration.
(2) The substrate is used: during detection, the ground surface is processed to be flat, and if the surface is uneven, a substrate is used to reduce test errors and ensure that the detected surface is smooth and flat as much as possible. After the field test is finished, whether sand leaks out among the bottom plate of the sand tank, the base plate and the ground or not is checked, if sand leaks out, the sand tank is separately cleaned, the mass of the sand tank is weighed, and the mass is deducted when the density is calculated.
(3) Measuring the use of sand: the sand measuring is in accordance with the rule, the sand measuring recovered is used, and the sand measuring needs to be screened, cleaned, dried and placed for enough time before the next use, so that the sand measuring is consistent with the clean and dry conditions in the calibration, and the density of the sand measuring is ensured. And the sand density is calibrated again when the sand is changed, so that the test accuracy is ensured.
(4) Shape of test pit: the test pit should be in the shape of a hollow cylinder, but construction units tend to dig the pit into the shape of a pan bottom, particularly near the bottom of the test pit. The more downwardly located, the less compacted zone is for each compacted layer, so that a test pit of such a shape will result in relatively less soil being removed from the looser zone, resulting in a greater measured compaction value.
(5) Depth of test pit: according to the requirement of the on-site test regulation of the road base surface, the depth of the test pit is equal to the thickness of the measured layer, but the lower layer material is not mixed, and the thickness of each compacted layer is 20cm in general, so the depth of the test pit is also 20 cm.
When the construction method is operated on site, the process of digging the pit is often completed by civil workers of construction units, and the pit digging depth of the construction method often cannot meet the requirement. The stress of the roller is distributed into an inverted triangle in the rolling process, so that the compaction degree of the part which is more downward is smaller for each layer of compaction. Thus, insufficient pit depth will result in a greater measured compaction.
The depth of the test pit is equal to the depth of the test pit in calibration as much as possible, the pit wall is straight, the diameters of the upper opening and the lower opening are equal, and the upper opening and the lower opening are prevented from being large and small or large. It is recommended that the depth of the pilot hole should be 15 cm. Because the detection is carried out according to the depth, the detection method is more in line with the actual situation, can better reflect the compactness of the measured layer and improve the detection working efficiency.
(6) Sand filling time: it is correct to observe that standard sand at the edge does not flow and then stop pouring the sand after ten seconds. Since the sand flow in the center is not directly observed and the sand flow starts in the center and then spreads to the edges. If the sand filling is finished in advance, the quality of the standard sand filled in is necessarily reduced, and the measured compaction value is increased.
(7) Selecting the water content: when the water content is selected, the soil in the test pit is quickly and uniformly stirred, and then the water content is taken.
During operation of the product, the steel ring is placed at a position where a pit hole is pre-formed, then the handle part is assembled in the positioning groove, the sliding block is inserted, and the handle part is guided by matching of the positioning opening and the positioning groove; when the handle part is matched in the positioning groove, the inserting plate is attached to the inner wall of the steel ring, the positioning of the inserting plate is realized by the steel ring, and the inserting plate is inserted into a soil layer after being downwards inserted and is continuously pressed to a proper depth; according to the method, the rest of the inserting plates are inserted, a cylindrical structure body is formed among the inserting plates after the inserting plates are inserted, soil in the structure body is taken out, the pit wall cannot collapse, and then the product is dismantled, so that the sand tank detection can be carried out.
The utility model has the advantages that: this product is easily collected the soil material, avoids collapsing of pitted wall, and the use of this product can obtain smooth pitted wall, and the structure of this product is comparatively simple, and the cost is comparatively cheap, is fit for using widely.
