The invention relates to a surface-layer fast solidification method for a soft foundation with dredger soil. The surface-layer fast solidification method includes steps of delimiting a construction region with the certain area and erecting a safe construction channel on the periphery of the construction region; laying two layers of non-woven fabrics on a soil surface in the construction region; building a shallow-layer water drainage plate; then distributing filter tubes among the non-woven fabrics to be used as water drainage channels and connecting submersible type vacuum pumps onto the filter tubes to realize vacuum water drainage; laying plastic membranes on the tops of the upper-layer non-woven fabrics to be used as air closure membranes; observing settlement on the membranes in a vacuum water drainage process and draining water accumulated on the membranes in time; using vibrators on the air closure membranes in good time to increase vibration load in the middle of a water drainage solidification period, and wrapping non-woven fabrics on the vibrators to realize membrane protection during vibration; and completing surface-layer solidification after bearing capacity of the solidified soil reaches 50Kpa or meets designed requirements. By the aid of the method, a work period can be shortened, work procedures such as work cushioning and the like are omitted, waste recovery of the soil is realized, solidification speed is fast, an effect is good, and assembly line production can be realized.

The invention relates to a drainage consolidation method without keeping drainage channel after work of a soft soil foundation, which can be recycled by a system. The method comprises the following steps of: impacting to form a hole by using a high pressure gun; pressing and burying a vertical drain filter pipe into the hole; connecting a flexible seepage filer pipe with the vertical drain filterpipe; connecting the other end of the flexible seepage filter pipe with a horizontal branch drain; connecting the horizontal branch drain with a horizontal main drain; paving geotextiles, and paving vacuum films on the geotextiles; connecting the horizontal main drain with a vacuum pump for vacuumizing; and detaching the parts, filling left holes, filling slag, excavating gutters, and impacting and compacting the slag layer by using impact compactor. The method overcomes the respective defects of the pile foundation technology, composite foundation technology and consolidated drained technology. In the method, recyclable vertical drainage filter pipe and horizontal main and branch drain structures are adopted, the construction cost is reduced, the field settlement after work is decreased, the transmission channel for vacuum pressure is widened, and the consolidation speed of the reinforced soil is improved.

The invention discloses a drainage composite self-drilling tire stringed bolt supporting structure and a construction method. The drainage composite self-drilling tire stringed bolt supporting structure aims to improve the stability of soft slopes and structurally comprises drainage boards, lattice beams, face boards and self-drilling tire stringed bolts. The self-drilling tire stringed bolts comprise hollow bolts, tires and drilling rods which are connected with one another; the drainage boards are drilled into soil from the tops to the bottoms of the slopes, and the self-drilling tire stringed bolts are constructed into the slopes from vertical slope surfaces between the two rows of drainage boards; the face boards and the lattice beams which perpendicularly intersect with one another are sequentially arranged on the slope surfaces, and the self-drilling tire stringed bolts penetrate the face boards and the lattice beams. The drainage composite self-drilling tire stringed bolt supporting structure has the advantages that air can be inflated into the self-drilling tire stringed bolts, accordingly, the tires can be expanded to squeeze the surrounding soil and can be anchored in stable strata, the self-drilling tire stringed bolts can be anchored at cross positions of the lattice beams by anchors and steel base boards, the spatial support structure can be formed, and the unstable soft soil can be anchored in the stable strata.
