1振动沉模防渗板墙技术特点1.1技术原理1.1.1振动机械原理利用振动机械的动力将空腹模板沉入地层,并向空腹板的腹内管道注满浆液,当振动模板提拔时,浆液在浆泵高压作用下,从模板底端注入槽孔内,边拔模板边注浆,随着模板的提出,自下而上形成了一道水泥砂浆墙体,由于相邻墙体连续作业,最后形成一条连续的防渗墙墙体。1.1.2振动沉模原理振动体系的竖向往复振动,将模板沉入地层,当激振力大于3种阻力(刃面的法向力、刃面的摩擦力的竖向分力,模板周边的摩擦阻力)时,模板便能沉
1 Vibration Shen mold anti-seepage wall technology features 1.1 Technical Principle 1.1.1 Vibration Machinery Principle The use of vibration mechanical power will be empty template sink into the stratum, and to the intra-abdominal tube empty web filled with slurry, when the vibration template promotion, the slurry Under the action of the high pressure of the slurry pump, the bottom of the mold is injected into the slot and the side of the mold is grouted while drawing the template. As the template is put forward, a cement mortar wall is formed from bottom to top. Due to continuous operation of adjacent walls, To form a continuous impervious wall. 1.1.2 Principle of vibration sinking mode The vertical reciprocating vibration of the vibrating system sinks the form into the formation. When the exciting force is greater than 3 kinds of resistance (normal force of blade face, vertical component of friction of blade face, Of the frictional resistance), the template will sink
