Test method suitable for testing hydraulic servo steel support effect
A test method suitable for testing the action effect of a hydraulic servo steel support comprises the following steps that 1, the outer contour of a foundation pit is obtained through lap joint of thin steel plates, and point positions needing inclination measurement are marked; 2, a hollow aluminum pipe is connected to the thin steel plate in a lap joint mode; 3, a thin aluminum pipe is connected below the hollow aluminum pipe to simulate a supporting stand column in the foundation pit; 4, assembling a propelling device in the pressurizing and pressure measuring system, and checking the air tightness of the propelling device after the propelling device is connected with a communicating hose; 5, connecting a propelling device with the hollow aluminum pipe to complete the installation of a set of device for simulating the hydraulic servo steel support; 6, the installed device is placed in a model box filled with a soil layer in advance; and 7, digging a soil layer according to requirements, controlling the air pressure pressed into the hollow aluminum pipe by using a propelling device, and observing the deformation condition of the thin steel plate. According to the method, the deformation condition of the enclosure structure of the foundation pit under the condition that different axial forces are applied is collected.
一种适用于测试液压伺服钢支撑作用效果的试验方法，包括以下步骤：步骤1：利用薄钢板搭接出基坑的外轮廓，标注好需要测斜的点位；步骤2：在薄钢板上搭接空心铝管；步骤3：在空心铝管下方连接细铝管以模拟基坑内支撑立柱；步骤4：组装好加压测压系统中的推进装置，连接上联通软管后检查推进装置的气密性；步骤5：将推进装置与空心铝管连接，完成一套模拟液压伺服钢支撑的装置的安装；步骤6：将安装好的装置放置到提前填好土层的模型箱中；步骤7：按照需求挖开出土层，并利用推进装置控制压入空心铝管的气压，观测薄钢板的变形情况。本发明采集施加了不同轴力情况下基坑的围护结构变形情况。
