Description

一种高含冰率冻土爆破模型制样装置 技术领域
本发明涉及一种制样装置，具体是一种高含冰率冻土爆破模型制样装置。
背景技术
随着多年冻土地区的工业建设，与冻土有关的工程问题，如冻胀、融沉、道路翻浆、融冻泥石流、边坡及路基失稳等随之而来，进行冻土爆破的模型试验为研究此类问题带来了非常重要的参考价值。在高含冰率土体人工冻结过程中，传统的冷板制样法会在土体冻结过程中产生水分迁移现象，导致冻土模型试样出现各部分含冰量不均匀的现象，同时，因为高含冰率土体质地较软，难以在未冻土体进行炮孔的预置，以往的制样方法是先冻结再钻孔，由于模型试验的尺寸通常比工程实际小，后期钻孔法会产生裂缝和热量，影响冻土试样的合格率。
发明内容
本发明提供了一种高含冰率冻土爆破模型制样装置，制样装置位于固定支架上，所述固定支架上设有第一电机和第二电机，同轴安置于支架两侧，固定支架中央安装有圆弧滑轨，第一电机和第二电机通过转轴连接制样装置，在支架顶部安装有水平指示器。

所述密封盖包括对称分布的第一送风管、第二送风管、第一回风管、第二回风管、固定在盖顶中央的制冷风机、预留在盖底中央的模具安装槽、 固定在模具安装槽内部的炮孔预置模具、盖体周围安装有环向紧箍密封装置，密封盖顶端设有温度控制器。
所述试样旋转器包括试样自转电机和试样旋转台，被固定在试样固定筒的中央，试样固定筒中央安装有试样仓，试样固定在试样仓中央，舱底安装有温度感应器通过无线信号连接到温度控制器。
进一步的，所述第一转轴和第二转轴的轴心即为圆弧滑轨的圆心，且两轴等径等长，刚性连接在制样装置两侧。
进一步的，所述第一滑轮和第三滑轮固定在试样固定筒上，第二滑轮固定在试样自转电机上，三个滑轮均在制样装置中轴线上，与圆弧滑轨接触。
进一步的，所述试样仓与炮孔预置模具通过密封盖提供的下压力紧密接合，形成一个不透水的密闭空间，严格控制试样的含水率。
进一步的，所述制冷风机采用风冷的方式对试样进行制冷，使试样仓外壁均匀受冷，第一送风管、第二送风管、第一回风管、第二回风管表面均设有隔热层，在插入密封盖主体的位置进行密封处理；
