Disclosed are novel cap layer compositions comprising: (a) an organic adsorption ingredient; (b)a non-organic silica carrier ingredient; and (c) an organic polymer delivery ingredient, wherein the cap layer composition is made by blending ingredients (a) through (c) in an integrated blending and delivery apparatus, the cap layer composition for use in an area in need of remediation.

Disclosed is a novel blending and delivery apparatus comprising: (a) a housing; (b) a first input port configured to receive an organic adsorption ingredient; (c) a second input port configured to receive an organic polymer delivery ingredient; (d) an intake chute configured to receive a non-organic silica carrier ingredient; (e) an auger driveshaft; (f) an auger coupled to the auger driveshaft; (g) a motor coupled to the auger driveshaft; and (h) a discharge opening; wherein the motor rotates the auger to blend the organic adsorption ingredient, the organic polymer delivery ingredient, and the non-organic silica carrier ingredient to form a capping composition layer mixture output via the discharge opening, where the capping composition layer mixture used to make a capping composition layer.

Disclosed are novel solutions in which a preexisting sediment capping system is integrated with improvements such as a cap ingredient processing and delivery apparatus, cap processing method and novel compositional cap product, whereby a hazardous site is remediated by delivering at least one novel cap composition layer over the contaminated subaqueous waterway or terrestrial substrate floor. One embodiment includes a powdered activated carbon (PAC) based cap layer produced by the system and methodology disclosed, the cap layer ingredients comprising predetermined ratio amounts of dry PAC and dry powdered 2-Hydroxypropyl guar gum (HGG) used as a safe and effective delivery ingredient, blended in a cap processing and delivering apparatus with a dewatered sand semi-slurry, the processed resulting capping composition being delivered in a manner such that a novel PAC cap layer is provided to a cap placement area in need of remediation.

The invention discloses a method for building an underwater construction comprising a hardened grout, wherein the device has a housing with a receiving volume, and moreover a filter apparatus which is arranged at least partially therein and which is designed to filter out constituents which have been released from the grout. A filter apparatus which can be used in the device, and a method for filling a device for building an underwater construction with a grout, using this filter apparatus, are moreover.

Disclosed in the present invention is a lifting and reinforcing process for a dust-free factory floor, including: reinforcing a soft foundation and precisely lifting a settlement range. Reinforcing a soft foundation includes: step 1: determining a depth of a soft soil layer in an inner settlement area of the factory, and designing a drilling curve; step 2: drilling guiding holes from the outer construction point of the factory; step 3: connecting and communicating grouting channels; and step 4: grouting. Lifting a settlement area includes: step 1: determining a depth range between the reinforced soft foundation and the floor, and designing the drilling curve; step 2: drilling the guiding holes; step 3: connecting and communicating the grouting channels; step 4: starting grouting; and step 5: stopping grouting.

According to an embodiment, a first concrete block is installed in a state in which a tubular waterproof membrane and a guide pipe are temporarily coupled to the first concrete block, then a second concrete block is installed, and subsequently concrete is poured into the tubular waterproof membrane and the guide pole is removed to form a concrete column, thereby allowing the concrete column to be connected to a body of the first concrete block by means of a column rebar assembly, such that the lower end of the concrete column is formed very firmly to thus greatly improve the stiffness of the entire concrete block structure. In addition, since the concrete column is formed by means of the concrete poured into the tubular waterproofing membrane, the concrete column can be formed in the same way as that in the land environment.

A pile installation apparatus and method of use thereof is provided for loading and installing a pile into an underlying ground surface. In one form, the pile installation includes: a mast; a vehicle mount for mounting the mast to a support vehicle; a carriage and drive assembly rotatably coupled to the mast and configured for vertical movement along the mast, said assembly including a rotational drive and drive shaft for mounting of a drive end of the pile thereon. The carriage and drive assembly configured to be rotatable relative to the mast between a loading position for loading a non-vertically oriented pile onto the drive shaft and an operable position for driving the pile into the underlying ground surface.

A pile plan map indicating a plurality of locations in a geographic area at which piles are to be installed is accessed. A first set of locations is identified from the plurality of locations and a first set of piles to be driven into the ground at the first set of locations using the pile plan map is identified. An order for driving the first set of piles into the ground is identified and a pile type for each of the first set of piles is identified. Basket assembly instructions are generated for assembling the first set of piles into a basket based on the identified order and the identified pile types. The first set of piles are assembled autonomously or manually into the basket based on the generated basket assembly instructions.
