Pile foundation for preventing and controlling earthquake liquefaction landslide of engineering soil slope and construction method of pile foundation
The invention discloses a pile foundation for preventing and controlling earthquake liquefaction landslide of an engineering soil slope and a construction method of the pile foundation. The pile foundation comprises a pile foundation body and an automatic earthquake liquefaction prevention and control system, wherein the pile foundation body comprises a pile cap, a hollow concrete pile foundation,a drainage pipe, a grouting guide pipe and a grouting pipe; the automatic earthquake liquefaction prevention and control system comprises a pore pressure sensor, a collecting instrument, an alarm anda water pump; when the pressure, collected by the collecting instrument, of pore water around the pile foundation obviously rises and exceeds an early warning value, the alarm gives an alarm, the water pump is started to pump water, the pressure of the pore water of soil around the pile foundation is reduced in time, and the damage risk of the earthquake liquefaction landslide of the engineeringsoil slope is prevented; and when a conventional displacement monitoring method is adopted for monitoring that slope deformation is too large or the deformation speed is too high and exceeds the earlywarning value, the alarm gives an alarm, a grouting limiter is used for positioning grouting, and deep treatment of the earthquake liquefaction landslide damage of the engineering soil slope is achieved.
本发明公开了一种工程土质边坡地震液化滑坡防治的桩基及其施工方法，该桩基包括桩基主体和自动化地震液化防治系统；桩基主体包括桩帽、空心混凝土桩基础、排水管、注浆导向管和注浆管；自动化地震液化防治系统包括孔压传感器、采集仪、报警器和水泵；当采集仪采集到的桩基周边的孔隙水压力明显升高超过预警值时，报警器报警并启动水泵抽水，及时降低桩基周边土体的孔隙水压力，预防工程土质边坡地震液化滑坡破坏风险；采用常规位移监测方法监测边坡变形过大或变形速度过快且超过预警值时，报警器报警，利用注浆限位器进行定位注浆，实现了工程土质边坡地震液化滑坡破坏的深度治理。
