Soft soil foundation pit supporting structure and construction method
The invention relates to the technical field of building construction, in particular to a soft soil foundation pit supporting structure and a construction method. Comprising a supporting plate and a bottom plate, the supporting plate is arranged in the circumferential direction of the bottom plate, the supporting plate is used for abutting against soft soil, the supporting plate is provided with a hollow fixing cylinder, and the fixing cylinder extends into the supporting plate and is detachably connected with the supporting plate; a plurality of movable columns are arranged in the fixed cylinder, a plurality of extending holes are formed in the fixed cylinder corresponding to the movable columns, the movable columns are slidably connected with the fixed cylinder through the extending holes, one end of each movable column can extend out of the fixed cylinder, the other end of each movable column is limited in the fixed cylinder, and a water absorption expansion part is further arranged in the fixed cylinder. A through water absorption channel is formed in the movable column, the water absorption expansion piece pushes the movable column to move in the direction away from the fixed cylinder after absorbing water, and the water absorption expansion piece is shaped after absorbing water. The fixing cylinder can be fixed in soft soil, and due to the fact that the fixing cylinder is connected with the supporting plate, the supporting plate and the soft soil are more stable.
本发明涉及建筑施工技术领域，尤其是涉及一种软土基坑支护结构及施工方法。包括支板与底板，所述支板环绕底板周向设置，所述支板用于与软土抵紧，所述支板上设置有固定筒，所述固定筒中空设置，所述固定筒伸入支板且与支板可拆卸连接；所述固定筒内设置有多个移动柱，所述固定对应移动柱开有多个伸出孔，所述移动柱借助伸出孔与固定筒滑动连接，所述移动柱一端可伸出固定筒，另一端被限制在所述固定筒内，所述固定筒内还设置有吸水膨胀件，所述移动柱上开有贯穿的吸水通道，所述吸水膨胀件吸水后推动移动柱朝向远离固定筒的方向运动，所述吸水膨胀件吸水后定型。固定筒能够固定在软土当中，由于固定筒与支板连接，因此支板与软土之间更为稳定。
