一、產(chǎn)品簡介：

容重測定儀用于現(xiàn)場測定原狀砂和礫質(zhì)土的密度。主要由有底盤，灌砂漏斗，容重瓶，閥門組成。結(jié)構(gòu)堅固耐久，采用不銹鋼材制成。

the product introduction:
The bulk density meter is used to determine the density of undisturbed sａnd and gravel soil on site. Mainly consists of a chassis, a sanding funnel, a bulk density bottle, and a valve. The structure is sturdy and durable, made of stainless steel.

二、技術(shù)參數(shù)：

★容砂瓶：4L；

★儀器尺寸：300 x 300 x 445mm （L x W x H）；

★重量：1.5Kg。

Second, technical parameters:
★ Sａnd bottle: 4L;
★ Instrument size: 300 x 300 x 445mm (L x W x H);
★ Weight: 1.5Kg.

三、使用說明：

★按灌砂法試驗中挖坑的步驟依據(jù)尺寸好試坑，稱試樣質(zhì)量，測定試樣的含水率，

★向容砂瓶內(nèi)注滿砂，關(guān)閥門，稱容砂瓶，漏斗和砂的總質(zhì)量，準(zhǔn)確至10 g。

★密度測定器倒置于挖好的空口上，打開閥門，使砂注入試坑。在注砂過程中不應(yīng)震動。當(dāng)砂注滿試坑時關(guān)閉閥門，稱容砂瓶、漏斗和余砂的總質(zhì)量，準(zhǔn)確至10 g，并計算注滿試坑所用的標(biāo)準(zhǔn)砂質(zhì)量，

★試樣的密度（PO）＝取自試坑內(nèi)試樣的質(zhì)量（MP）÷(注滿試坑所用標(biāo)準(zhǔn)砂的質(zhì)量（MS）÷標(biāo)準(zhǔn)砂的密度（PS）)。

★試樣的干密度（Pd）=｛取自試坑內(nèi)試樣的質(zhì)量（MP）÷（1＋0.01w1）｝/(注滿試坑 所用標(biāo)準(zhǔn)砂的質(zhì)量（MS ÷標(biāo)準(zhǔn)砂的密度（PS）)。

灌砂法容重測定儀計算公式

V、P。V＝m3×VW　 P＝m5/V

　　 式中：V——測定器的容積，cm3　　　

m3——灌滿測定器所需水的質(zhì)量（m2－m1）g

VW——不同溫度下每克水的體積，cm3/g

P——標(biāo)準(zhǔn)砂密度，g/ cm3

m5——充滿測定器所需砂的質(zhì)量（m4－m1）g

Third, the instructions for use:
★ According to the steps of digging pits in the test of sａnd filling method, the test pit is based on the size, the mass of the sample is called, and the moisture content of the sample is determined.
★ Fill the sａnd bottle with sand, close the valve, call the sａnd bottle, the total mass of the funnel and sand, accurate to 10 g.
★ The density measuring device is placed on the excavated air opening, and the valve is opened to inject the sａnd into the test pit. It should not be shaken during the sａnd injection process. When the sａnd is filled with the test pit, the valve is closed, and the total mass of the flask, funnel and residual sａnd is said to be accurate to 10 g, and the standard sａnd quality used for filling the test pit is calculated.
★ Density of the sample (PO) = mass of the sample (MP) taken from the test pit (the mass of the standard sａnd used for filling the test pit (MS) the density of the standard sａnd (PS)).
★The dry density of the sample (Pd)={take the mass of the sample in the test pit (MP)÷(1+0.01w1)}/(the mass of the standard sａnd used for filling the test pit (MS ÷standard sａnd density (PS) ).
Sanding method bulk density measuring instrument calculation formula
V, P. V=m3×VW P=m5/V
Where: V——the volume of the measuring device, cm3
M3 - the mass of water required to fill the tester (m2-m1)g
VW - volume per gram of water at different temperatures, cm3/g
P——standard sａnd density, g/cm3
M5 - the mass of sａnd required to fill the tester (m4-m1)g
