Concrete lining internal and external water pressure difference adjusting device
The invention discloses a concrete lining internal and external water pressure difference adjusting device, and belongs to the technical field of engineering. The pressure difference adjusting device comprises a valve body cylinder, a piston, a rubber water stop strip and a spring; the valve body cylinder is embedded in a reinforced concrete lining, the piston is installed in the valve body cylinder, a rubber water stop strip is arranged between a valve body cylinder top plate and a piston top plate, the two ends of the spring are connected between a piston bottom plate and the valve body cylinder bottom plate, a drainage hole is formed in the piston top plate, and a drainage pipe is connected to the valve body cylinder bottom plate. The piston bears the effects of internal water pressure and external water pressure at the same time, when the internal and external water pressure difference is larger than the starting pressure difference set by the piston, the spring is compressed, external water is discharged into the reinforced concrete lining from the interior of the valve body barrel and the drainage pipe, along with the external water discharging, the pressure difference is reduced, the spring extends, the piston moves upwards and then resets, and the device returns to the initial sealing state. The structure damage or instability caused by high external water pressure seepage damage of the lining structure can be avoided.
本发明公开了一种混凝土衬砌内外水压差调节装置，属于工程技术领域。压差调节装置包括阀体筒、活塞、橡胶止水条和弹簧；阀体筒埋设在钢筋混凝土衬砌中，活塞安装在阀体筒内部，阀体筒顶部板与活塞顶部板之间设橡胶止水条，弹簧的两端连接在活塞底部板与阀体筒底部板之间，活塞顶部板上设有排水孔，阀体筒底部板上连接排水管，活塞同时承受内水压力和外水压力的作用，当内外水压力差大于活塞设定的启动压力差，弹簧压缩，外水从阀体筒内部和排水管排入钢筋混凝土衬砌内部，随着外水排入，压差减小，弹簧伸长，活塞上移后复位，装置回到初始密封状态，本发明能够避免衬砌结构的高外水压力渗流破坏导致的结构产生损毁或失稳。
