Abstract
A sand cone method density test auxiliary device comprises a locating ring and a fixed board, wherein the locating ring is connected with the fixed board, the thickness of the locating ring is slightly smaller than that of the fixed board, the diameter of the locating ring is the same as that of the bottom of a sanding filling tube, and the fixed board is provided with fixed clips. The fixed clips are four in number and are connected with the fixed board in cross direction, and the fixed clips are provided with a fixed drilling rod. The sand cone method density test auxiliary device enables a base board to be fixed during a whole test process, and enables the position of the sand filling tube on the base board to be located.
Description
Technical field
The utility model relates to a kind of sand replacement method density test servicing unit.
Background technology
In the highway construction, for the quality of filling compacting of roadbed, basic unit and subbase, the density test after need rolling.And generally be no more than the density test of fine grained soils, sandy soil and the gravelly soil of 40mm for maximum particle diameter, adopt sand replacement method to detect usually.Coarse compaction plane for cleaning after clean at first will be measured the amount chiltern amount between substrate and matsurface, then takes away substrate and holes, and substrate is put at last again, irritates sand in the middle of the filling sand tube of the amount of filling sand is placed in substrate.In this process, the variation of twice placement location before and after the substrate, irritate the accurately circular hole on the align substrates of sand tube, all can exert an influence to result of the test.
Summary of the invention
The purpose of the utility model provides a kind of sand replacement method density test servicing unit, substrate is fixed in entire test, and positioned irritating the position of sand tube on substrate.
The above-mentioned purpose of the utility model is to realize through such technical scheme: sand replacement method density test servicing unit; Comprise locating ring; Fixed head, said locating ring is connected with fixed head, and the thickness of said locating ring is slightly less than fixed head; The diameter of said locating ring equates that with the base diameter of irritating the sand tube said fixed head is provided with fixed card.Said fixed card is four, is the cross direction and is connected with fixed head, and fixed card is provided with fixedly pricker.
A kind of sand replacement method density test of the utility model servicing unit is fixed fixed card through fixing pricker, and then fixing base, and locating ring positions irritating the position of sand tube on substrate simultaneously.Because employing the utility model device, does not move substrate position in entire test, and locating ring is accurately located irritating the position of sand tube on substrate fast, thereby has guaranteed that test operation is convenient, test result is more accurate.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
Fig. 1 is the utility model device floor map.
Fig. 2 is the utility model device elevational schematic view.
Fig. 3 is that the utility model device is installed and used sketch map.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3; Sand replacement method density test servicing unit comprises locating ring 1, fixed head 2; Said locating ring 1 is connected with fixed head 2; The thickness of said locating ring 1 is slightly less than fixed head 2, and the diameter of said locating ring 1 equates that with the base diameter of irritating the sand tube said fixed head 2 is provided with fixed card 3.Leave the pricker hole on the fixed card 3, being convenient to fixedly, pricker 4 passes.
Locating ring 1 material adopts steel plate, and thickness is about 2mm, and diameter and filling sand tube bottom equal diameters are 250mm (Ф 150mm irritates the sand tube) or 280mm (Ф 200mm irritates the sand tube).
Fixed head 2 materials adopt the 3mm steel plate, and it is of a size of locating ring 1 diameter and adds that 50mm gets final product.
The thickness of locating ring 1 is slightly less than fixed head 2; Mainly be that locating ring 1 forms a concave surface on fixed head 2; The diameter of concave surface equates with filling sand tube bottom; Can accurately be placed on the locating ring 1 so that irritate the sand tube, thereby so that irritate how much centerings of sand tube and examination hole, guaranteed discharge sand bleeds in the examination hole accurately.
The material of fixed card 3 and locating ring 1, fixed head 2 are consistent, and thickness is 3mm.
Implementation step:
During test, substrate 5 is placed on the having an even surface of an about 40mm * 40mm, and has cleaned on the earth material after the clean compacting, the utility model device is positioned on the substrate 5, fixed card 3 is provided with fixedly pricker 4, fixes with fixing 4 pairs of fixed card 3 of pricker.In the circular hole of locating ring 1 and substrate 5, put the soft gauze of one deck, attention should make the open and flat corrugationless of gauze.The filling sand tube that certain mass amount sand is housed is positioned on the locating ring 1, carries out irritating sand the first time, open and irritate sand tube switch; The amount of letting sand flow on the gauze; Close switch when the sand in irritating the sand tube is no longer dirty, take off the quality of irritating sand in sand tube and the weighing tank, the amount sand on the gauze is regained.Hole along the substrate mesopore, the earth material of cutter pine is taken out put in the polybag, and sealing, all quality of samples are claimed in the polybag in the back that finishes of holing.Inwall is put the soft gauze of one deck along the examination hole in locating ring 1; Attention should make the open and flat corrugationless of gauze, and the filling sand tube that certain mass amount sand is housed is positioned on the locating ring 1, carries out irritating the second time sand; Open and irritate sand tube switch; Close switch when the sand in irritating the sand tube is no longer dirty, take off the quality of irritating sand in sand tube and the weighing tank, the amount sand on the gauze is regained.The wet density of tested earth material equals to try the volume of the wet quality of earth material in the hole divided by the examination hole, and the volume in examination hole equals the density of the difference of twice amount of pouring into sand divided by amount sand.
