中低壓固結儀

（輕便型、雙聯、三聯通用）

一、 概述：

首先歡迎購買使用本廠產品。

此產品用于進行土的壓縮試驗，測定土的變形與壓力或孔隙比與壓力的關系以及變形量與時間的關系，從而計算土的單位沉降量，壓縮系數和指數、回彈指數、壓縮模量、固結系數等等，測定項目要與工程需要而定。（執行標準：GB /T0137-1993）

《雙聯中低壓儀器凈重（不含砝碼）70kg，外形尺寸（685*450*1100）mm》

《三聯中低壓儀器凈重（不含砝碼）85kg，外形尺寸（685*800*1100）mm》

《輕便型中低壓儀器凈重（不含砝碼）40kg，外形尺寸（220*710*560）mm》

二、技術指標：

1.試樣面積分為30cm2與50cm2。

2.中壓壓力范圍30cm2（12.5-1600）Kpa/50cm2（12.5-800）Kpa。

  低壓壓力范圍30cm2（12.5-800）Kpa/50cm2（12.5-400）Kpa。

3.土樣高度20mm。

4.杠桿比例1:12與1:10.

三、產品結構：

1、土樣容器試模，每臺儀器有兩套容器試模，每套容器分別作30cm2與50cm2兩種土樣面積試驗，土樣均為20mm。 

 還有渦輪箱體， 它可以調節杠桿支點的升降，行程15mm。試驗時先將杠桿調至水平位置，當土樣受壓下沉導致杠桿傾斜時，可逆時針旋轉手輪，降低杠桿支點使杠桿恢復水平狀態，以保證各級荷重的j確度。

1.手輪 2.木臺板 3.容器 4.百分表（自備）5.表夾夾具 6.傳壓頭 7.橫梁 8.平衡錘

9.升降桿  10.下橫梁  11.杠桿  12.水平氣泡  13.吊鉤（1:12）  14.吊鉤（1:10）

15.砝碼掛盤

四、使用說明：

注意：調平時掛上砝碼吊盤調平（吊盤不算加載載荷）

      30cm2為1:12吊鉤加荷

      50cm2為1:10吊鉤加荷

1. 將儀器放置平穩，并使杠桿位于升降支架之間，使之不產生摩擦。

2. 按土工試驗規程制備土樣，裝入護環后放入容器中透水石上，然后上端放上透水石、傳壓板，置于壓框正中，安裝百分表。將手輪順時針方向旋轉，使升降桿上升到頂點，再逆時針方向旋轉1-2圈，然后使加壓頭對準傳壓板，調整橫梁上端螺桿，是框架向上時容器部分能自由取放，即可按土工操作規程先施加1Kpa的預壓載重（30cm2試樣時，掛小的重量25.5g）。調整量表，使指針讀數為零。以后按規程逐級加荷，（加荷前卸下預載荷砝碼）

3. 在加荷以后經常管觀看杠桿下沉情況或根據需要可逆時針方向旋轉手輪，調節升降桿保持杠桿平衡。（在下一級加載前可適量調高，以縮小杠桿傾斜角度），此時一般不要順時針方向轉動手輪，以防產生間隙震動土樣。

4. 每次使用后，應將儀器全部擦拭干凈，如估計有較長時間不用，應在金屬表面涂以薄層油脂，以防銹蝕。
