Description
Technical field
The utility model relates to a kind of checkout equipment, particularly relates to a kind of roadbed filling compacted density detector.
Background technology
The density measurement of soil detects one of Subgrade Compaction Quality main experimental, and its test method comprises core cutter method, wax coating method, sand replacement method, douche, air-bag method and nucleon ray method; For the density measurement of coarse-grained soil, douche is the most frequently used test method.At present, the key instrument equipment that douche adopts comprises water storage cylinder, table scale, plastic film bag, shoveling instrument and soil container.During test, by plastic film bag along the end of testing pits, hole wall closely connected putting into test pits, initial water level height in record water storage cylinder, open the water injection pipe of water storage cylinder, allow water slowly flow into and test pits in interior plastic film bag, water injection pipe is closed immediately, height of water level when water filling stops in record water storage cylinder when the water surface flushes with near coal-mine ground; When in cylinder, initial water level and water filling stop, the difference of height of water level, with the product of water storage cylinder cross sectional area, is volume of testing pits; The interior ratio by the soil dug out and volume of testing pits of testing pits is the density of soil.In process of the test, for the judgement that water filling stops, need laboratory technician's ground proximity to observe the water surface and whether flush with near coal-mine ground; Due to surface tension and the collimation error of water, whether the manual observation water surface flushes with near coal-mine ground, and existence is wasted time and energy, and test efficiency is low, and easily occurs error.
Summary of the invention
The purpose of this utility model is to provide a kind of roadbed filling compacted density detector.
The purpose of this utility model is achieved through the following technical solutions:
Roadbed filling compacted density detector of the present utility model, comprise base plate, described base plate is provided with liquid storage cylinder, LOAD CELLS is provided with between described liquid storage cylinder and base plate, the bottom of described base plate is provided with liquid level sensor, and the top of described liquid storage cylinder is provided with fill orifice, and the bottom of described liquid storage cylinder is provided with liquid outlet and is provided with gauge tap, described liquid outlet is through described base plate, and described LOAD CELLS is connected with data processing equipment respectively by wire with liquid level sensor.
The technical scheme provided as can be seen from above-mentioned the utility model, the roadbed filling compacted density detector that the utility model embodiment provides, because base plate is provided with liquid storage cylinder, LOAD CELLS is provided with between liquid storage cylinder and base plate, the bottom of base plate is provided with liquid level sensor, the top of liquid storage cylinder is provided with fill orifice, the bottom of liquid storage cylinder is provided with liquid outlet and is provided with gauge tap, liquid outlet is through base plate, LOAD CELLS is connected with data processing equipment respectively by wire with liquid level sensor, there is instrument light, easy and simple to handle, data are reliable, automatic control flow, the advantages such as automatic calculating, improve the reliability of test efficiency and testing result, be suitable for roadbed filling to detect.

Roadbed filling compacted density detector of the present utility model, has the advantages such as instrument is light, easy and simple to handle, data reliable, automatic control flow, automatically calculating, improves the reliability of test efficiency and testing result, be suitable for roadbed filling and detect.
Beneficial effect:
1. automatic decision is tested pits and is filled up solution by the utility model, avoids the error that Traditional Man is observed.
2. data processing equipment automatic data collection, result of calculation, test pits volume, density etc., ensure that data are accurately objective.
Specific embodiment, as shown in Figure 1:
1. on road bed to be detected, choose test point, prepare to test pits by the degree of depth of code requirement, diameter, and take the quality of interior soil of testing pits.
2. pave on surface of testing pits plastic sheeting.
3. roadbed filling compacted density detector is positioned over top of testing pits, base plate is concordant with top of testing pits.
4. open data processing equipment, start test.In liquid storage cylinder, note enough water, now gauge tap keeps closed condition.LOAD CELLS image data.
5. open gauge tap, water is in liquid storage cylinder flows out to and tests pits.
6. in time trying underground water and fill, be positioned at bottom base plate, the liquid level sensor at top of testing pits gathers this signal automatically, and transfers to data processing equipment, and LOAD CELLS gathers now data simultaneously.
7. according to the change of water quality in liquid storage cylinder, and interior quality of soil sample of testing pits, data processing equipment calculates test pits volume and soil body wet density automatically.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
