The present invention provides a method for repairing a rubble-type structure, and a rubble-type structure constructed using this repair method, which involves filling a hole formed by the detachment of a covering stone from the covering stone layer with a covering material of sufficient size, thereby firmly interlocking the covering material with the existing covering stones forming the inner surface of the hole. [Solution] A fabric formwork 6 that can expand into a three-dimensional shape is laid in a sheet-like state inside the hole 5 of the covering stone layer 3 that covers the base part 2. Next, fluid underwater concrete 7 is injected into the fabric formwork 6 to expand it, and the fabric formwork 6 expanded by the underwater concrete 7 is used as a covering material to fill the hole 5 and to enter between the existing covering stones 3a that form the inner surface of the hole 5.

The present application relates to the technical field of offshore foundation construction, and discloses a method for drilling into a collapsed backfilling section of a near-shore rock-filled hole, comprising the following construction steps: 1) forming a concrete slab on a rock-filled layer at a construction site; 2) drilling a pre-drilled hole section in the concrete slab by a rotary drilling machine; 3) inserting a casing into the pre-drilled hole section; 4) rotating the casing into the rock-filled layer by the rotary drilling machine, and forming a collapsed area between the concrete slab and the rock-filled layer; 5) drilling a peripheral hole in the concrete slab and connecting the peripheral hole with the collapsed area; 6) backfilling the peripheral hole with peripheral clay to fill the collapsed area; 7) the rock-filled layer has in-hole rock filling and in-hole clay backfilling; 8) extruding the in-hole clay into the gap of the in-hole rock filling by a punching hammer in the casing, and synchronously crushing the in-hole rock filling until the punching hammer penetrates the rock-filled layer to form a rock-filled hole section, thereby avoiding further expansion of the collapsed area and realizing stable and efficient drilling construction effect.

The disclosed embodiments describe systems, methods, and devices for a fluid run-off system. These systems, methods, and devices may include a fluid run-off system which may comprise a layer of foundation stone, at least one stormwater management system located above the layer of foundation stone, a layer of embedment stone located around the at least one stormwater chamber, a layer of initial fill located above the layer of embedment stone, a layer of final fill located above the layer of initial fill, a filtration fabric located around a perimeter of the layer of foundation stone and the layer of embedment stone, and a geogrid system located around a perimeter of the filtration fabric.

This invention relates to the technical field of near-shore foundation construction, and discloses a method for combined drilling and pile formation of cast-in-place piles in deep rock-fill layers near the coast. The method includes the following steps: 1) A rotary drilling rig lowers a casing into the rock-fill layer; 2) The rock-fill layer has a collapsed area and an outer peripheral hole; 3) Clay is backfilled into the outer peripheral hole, filling the collapsed area; 4) The rock-fill layer has stones inside the hole and clay is backfilled inside the hole; a perforating hammer is used to drill a hole in the casing until a rock-fill section is formed; 5) The rotary drilling bucket drills into the soil layer until a soil section is formed; 6) The rotary drilling bucket drills into the rock layer until the bearing stratum is formed, creating a rock section. The rock-fill section, soil section, and rock section together form the pile hole; 7) A reinforcing cage is lowered into the pile hole; 8) Concrete is poured into the pile hole, and after the concrete solidifies, a cast-in-place pile is formed. Through optimization of the casing installation, rock-fill drilling, segmented pile formation, and casing removal, efficiency improvement and quality assurance are achieved.
