Cross beam soil anchor type traction assembly type open caisson device and method
The invention discloses a cross-shaped beam soil anchor type traction assembly type open caisson device which comprises a prefabricated well section, a cross-shaped beam is arranged in the prefabricated well section, soil anchor holes are formed in the cross-shaped beam, and blade feet are arranged at the bottom of the prefabricated well section; the traction assembly comprises a soil anchor, a counter-force frame and a jack, the soil anchor penetrates through the soil anchor hole and is drilled into the soil body below the cross beam by a certain depth, the counter-force frame is arranged at the top end of the soil anchor and located above the cross beam, and the jack is arranged between the cross beam and the counter-force frame. The method is used for sinking construction of the open caisson, the cross beam is pulled down through the soil anchor, the reaction frame and the jack, and sinking of the prefabricated well section is achieved; through data of the gradienter and the pressure sensor, the stroke of the jack is adjusted in real time, the counterforce is coordinated, and the problems of uneven settlement and the like are avoided. In addition, the invention further discloses a cross beam soil anchor type traction assembly type well sinking method.
本发明公开了一种十字梁土锚式牵引拼装式沉井装置，其包括，预制井段，其内部设置有十字梁，十字梁上布置有土锚孔，预制井段底部设置有刃脚；牵引组件，包括土锚、反力架和千斤顶，土锚穿过所述土锚孔钻入十字梁下土体一定深度，土锚顶端设置有反力架，反力架位于十字梁上方，千斤顶设置于十字梁和反力架之间。本发明用于沉井的下沉施工，利用土锚、反力架和千斤顶下拉十字梁，实现预制井段的下沉；通过水平仪和压力传感器的数据，实时调整千斤顶的行程，协调反力大小，避免出现不均匀沉降等问题。此外，本发明还公开了一种十字梁土锚式牵引拼装式沉井方法。
