Abstract
In the earthwork testing, manipulated soil is usually tamped by a soil stroking machine and made into a test sample so as to measure the engineering mechanic property of the manipulated soil. The new-type soil tamper is characterized in that the center of a shaft and a bottom base is provided with a through hole, and the gas can be expelled from the through hole when the soil molded specimen is stroked; the through hole can effectively prevent or reduce the fine particle soil from being taken out by the compressed gas from a die cylinder, and thus the accuracy of test can be improved. The utility model is suitable for the molded specimen of the earth work apparatus of GS-1 type resonance poles in peculiar; the utility model can ensure that the lading fine steel wire of the new-type soil tamper is positioned on the central axle line of the test sample.
Description
The utility model belongs to the instrument that soil test is used.
When carrying out native engineering properties test, the Chang Yaoyong soil tamper is with loose earth material, at the sample that becomes in the mould tube or directly the specimen mount higher slice in the triaxial cell hits the certain density of real one-tenth.Then, measure the various character of the engineering mechanics of soil, for the correct design of building and foundation provides necessary parameter.Hit earth forming with existing soil tamper, because after being mixed in gas in the earth material and hit by soil tamper, sharply from becoming the gap between mould tube and the soil tamper to go out, often that quality is less fine grained soil, resembling the less fine grained soil of flyash one class proportion especially takes out of from become the mould tube, thereby make sample density inaccurate, bring certain error to result of the test.In addition, the earthwork test Instrument that has, GS-1 type resonance column device for example, one of the specimen mount center pass-out of triaxial cell is in order to apply axial load σ
1Finer wire, it passes with sample top cap along the sample axis and is connected.For such geotechnological instrument, because the existence of loading finer wire on the base just can not use existing soil tamper to hit earth forming.
When the purpose of this utility model is to hit the earth forming sample, the gas that is mixed in the earth material can be discharged smoothly; And can be applied to the earthwork test Instrument of this class of GS-1 type resonance post.
Description of drawings:
Fig. 1 represents the vertical section schematic diagram of the utility model soil tamper.
Symbolic significance is among the figure: 1---fall apart from alignment pin; 2---centre bore; 3---axostylus axostyle; 4---hammer; 5---base.
The utility model and existing soil tamper main distinction feature are that axostylus axostyle (3) and base (5) center have a circular hole (abbreviation centre bore) that runs through two ends, and the diameter of centre bore is that 2mm is to 4mm. As be used on the geotechnological instrument of GS-1 type Resonant Column one class, center-hole diameter should be greater than about above-mentioned loading finer wire 1mm.
The utility model has following advantage:
1. when hitting the earth forming sample, being mixed in the earth material gas can discharge from the soil tamper centre bore, thereby can avoid or reduce the situation that fine grained soil is rushed out from the gap that becomes mould tube and soil tamper, so just can eliminate or reduce because the earth material loss causes sample density to change caused testing error.
2. can be used on the earthwork test Instrument of GS-1 type resonance post one class and hit the earth forming sample.
3. be used in when hitting the earth forming sample on the GS-1 type resonance post one class geotechnique instrument, the centre bore of this soil tamper is enclosed within the loading finer wire outside of GS-1 type instrument, the loading finer wire accurately is positioned on the axle center of sample, thereby the axial stress of sample inside is evenly distributed, the guarantee test precision.
Claims (1)
1, a kind of novel soil tamper that is used for the moulding of soil test sample is formed apart from alignment pin 1, axostylus axostyle 3, hammer 4 and base 5 by falling, and feature of the present utility model is at the center of axostylus axostyle 3 and base 5 centre bore 2 that runs through two ends to be arranged.
