Prograding mudflat foundation reinforcing device and construction method thereof
The invention discloses a prograding mudflat foundation reinforcing device and a construction method thereof. The reinforcing device comprises hollow steel plates, hollow steel cylinders, steel strands, solid steel balls, a sand cushion layer, a vacuum device, an electro-osmosis device and a vacuum sealing film. The hollow steel plates are transversely laid, the hollow steel cylinders are arrangedat the joints of the hollow steel plates, and the hollow steel plates and the hollow steel cylinders are connected into a whole through bolts. One ends of the steel strands are connected with the solid steel balls, and the other ends of the steel strands are connected with a positive electrode of the electro-osmosis device and fixed to the middle of the hollow steel plate. The hollow steel cylinders are connected with a negative electrode of the electro-osmosis device. The sand cushion layer is arranged on the upper portions of the hollow steel plates, the vacuum device is embedded in the sand cushion layer, and the vacuum sealing film is laid at the top of the sand cushion layer. The method comprises the following steps that the solid steel balls, the hollow steel plates, the hollow steel cylinders, the sand cushion layer, the vacuum device, the electro-osmosis device and the vacuum sealing film are installed; and vacuumizing, sedimentation consolidation, electrifying, sedimentationconsolidation and vacuum consolidation are conducted. According to the prograding mudflat foundation reinforcing device and the construction method thereof, the shear strength of soil and the bearingcapacity of a foundation are improved while it is guaranteed that the sedimentation and the sedimentation difference are within a control range, and the water content is reduced.
本发明公开了一种淤长型滩涂地基加固装置及其施工方法，所述加固装置包括空心钢板、空心钢筒、钢绞线、实心钢球、砂垫层、真空装置、电渗装置和真空密封膜，空心钢板横向平铺，空心钢板连接处设置空心钢筒，用螺栓连为整体，钢绞线一端与空心钢球相连，另一端与电渗装置正极相连固定于空心钢板中部，空心钢筒与电渗装置负极相连，空心钢板上方设置砂垫层，砂垫层内埋设真空装置，砂垫层顶部铺设真空密封膜。所述方法包括以下步骤：安装实心钢球、空心钢板、空心钢筒、砂垫层、真空装置、电渗装置、真空密封膜；抽真空，沉降固结，通电，沉降固结，真空固结。本发明保证沉降、沉降差在控制范围内的同时提高土的抗剪强度和地基承载力，降低含水率。
