Abstract
The utility model relates to it is a kind of be used to prepare disturbance soil sample hit sample device, structure feature is three valves set upper mold hoop, and bolt-connection, and on bolt inserted base, tightening nut will be on bolt firm banking；Movement weight rod bar is equipped with screw and position-limited hoop, is placed in the top of limit hammer ram, and with limit ram contacts, limit hammer ram is embedded in three valves, and can be moved up and down in three valves；It is successively changed in three valves and weighs the wet soil of the high casing of three valve one thirds, the high casing of three valve 2/3rds and three valves grade height casing quality, pour into three valves, movement weight rod hits reality, completes the preparation of sample first layer, the second layer and third layer soil sample successively.The depth that hammer ram is limited by converting the height of casing realizes the requirement remolded when prepared by sample to dry density and flatness.
Description
Technical field
It is specifically a kind of to be used to prepare hitting for disturbance soil sample the utility model relates to hammer, suppress the utensil of soil sample
Sample device.
Background technique
Rammed earth technology is that have far-reaching shadow on architectural history with one of widest method of construction in China's earth building
It rings, the Great Wall is exactly that some remote districts of best witness or even today are still using this method compacting foundation, builds room
Room.
It disturbs soil sample preparation and usually utilizes the stress-of the measurement soil such as unconfined compressive strength, triaxial apparatus indoors
Strain stress relation determines intensity index, studies and establish criterion of strength and strength theory.The accuracy when preparation of soil sample is the test
The key of required soil strength index can accurately be measured.The sample device used at present that hits is extremely difficult to " Standard for test methods of earthworks "
Requirement in GB/T50123-1999 to disturbance soil sample preparation influences to test so the index parameter discreteness measured is larger
Accuracy.
Summary of the invention
In order to reach the accuracy when preparation of soil sample, overcome the shortcomings of that the existing sample device that hits influences disturbed soil mechanical test,
The purpose of this utility model is to provide a kind of disturbance soil samples that is used to prepare to hit sample device.This, which hits sample device, can accurately control remodeling
Requirement when prepared by soil sample to density and flatness, and it is simple to operate, and sample preparation is high-efficient.
The purpose of this utility model is realized using emerald technical solution:
A kind of disturbance soil sample that is used to prepare hits sample device, by pedestal, bolt, mould hoop, nut, movement weight rod, position-limited hoop, spiral shell
The high casing groups such as nail, limit hammer ram, the high casing of three valve one thirds, three valves, the high casing of three valve 2/3rds, three valves
At.Three valves cover upper mold hoop, and bolt-connection, and on bolt inserted base, tightening nut will be on bolt firm banking；Weight rod end
Portion be equipped with screw and position-limited hoop, be placed in limit hammer ram top, and with limit ram contacts, limit hammer ram in fall groove profile, insertion
In three valves, and it can be moved up and down in three valves.It is successively changed in three valves and weighs the high casing of three valve one thirds, three valves
The wet soil of 2/3rds high casings and three valves grade height casing quality pours into three valve movement weight rods and hits reality, completes first successively
The preparation of layer, the second layer and third layer soil sample.
The beneficial effects of the utility model are:
1, the flatness and dry density value of interfloor height when remodeling sample preparation, sample can be accurately controlled, instrument knot is enough
Simply, detachably, easy to operate, sample preparation is high-efficient.
2, it is actual to determine that intensity index has convenient for the strain-stress relation of measurement soil for the soil sample of the utility model preparation
Application value provides technical support with this to study and establishing disturbed soil probe intensity criterion and strength theory, has guidance
Meaning.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the high casing of three valve 2/3rds.
Fig. 3 is the high casings such as three valves.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further detail technical solutions of the utility model again:
As required by Fig. 1.A kind of disturbance soil sample that is used to prepare hits sample device, by pedestal 1, bolt 2, mould hoop 3, nut 4, again
Hammer stem 5, position-limited hoop 6, screw 7, limit hammer ram 8, the high casing 9 of three valve one thirds, three valves 10, three valves 2/3rds are high
The high casing 12 such as casing 11, three valves forms.Three 10 sets of valve upper mold hoops 3, couple with bolt 2, in 2 inserted base 1 of bolt, twist
Tight nut 4 will be on 2 firm banking 1 of bolt；Movement weight rod 5 is equipped with screw 7 and position-limited hoop 6, is placed in the top of limit hammer ram 8,
It is contacted with limit hammer ram 8, limit hammer ram 8 is embedded in three valves 10, and can move up and down in three valves 10 in groove profile.
The quality for weighing high 9 wet soil of casing of three valve one thirds is poured into three valves 10., and extraction screw 7 and position-limited hoop 6, weight are loosened
Hammer is tried with the upper contact soil that the power of 15N is hit between the high casing 9 of actual arrival limit 8 three valve one third of hammer ram and three valves 10
Sample completes the compacting of sample first layer soil sample, equally, successively changes in three valves 10 and weigh the high casing of three valve 2/3rds
11 and three valve grade height casings, 12 mass wet soil, pour into three valves, 10. weight and hit reality, successively complete first layer, the second layer and
The preparation of third layer soil sample.
The utility model disturbance soil sample hit sample device can accurate control disturbance soil sample preparation when interfloor height, sample
It is required that dry density value and sample flatness, not only easy to operate, but also sample preparation is high-efficient, the test data measured is accurate
Reliably.
