A precast concrete molded body is provided, which is a cured product of a concrete composition. The concrete composition comprises: a microcapsule; cement; and at least one type of aggregate. The microcapsule is provided with a core-shell structure having i) a core made of a water repellent organosilicon material selected from the group consisting of organosilanes, organosilane partial condensation products, and branched siloxane resins, and ii) a shell made of a silicon-based network polymer containing silica units. The concrete composition contains 0.01 to less than 0.5 parts by weight of microcapsules per 100 parts by weight of cement. Thereby, a precast concrete molded body can be provided, having high strength, as well as at least one of the following properties: air content stability, substance penetration prevention, and freeze-thaw resistance.

A prefabricated foundation system for mounting one or more electric vehicle charging stations is provided. The prefabricated foundation system includes a body, including a top opening, a plurality of sidewalls, and a plurality of sidewall openings, wherein each of the plurality of sidewalls includes at least one sidewall opening. The prefabricated foundation system further includes a lid configured to be secured to the body over the top opening. The lid includes a lid opening configured to receive one or more components of the one or more electric vehicle charging stations.

System and means soil stabilization and moisture control for building foundations including methods and systems for stabilization moisture in a site for building foundation by applying soil moisture stabilization material in various forms, a preferred stabilization material being a mixture of aluninosilicate Pozzolan mineral and granular material such as sand.

The invention belongs to ecological revetments in the technical field of river ecology, which particularly involves an ecological revetment to regulate wandering rivers. The ecological revetment is composed of porous concrete-piles, ecological connecting-plates, an ecological viewing-corridor and a slope green-belt. The ecological landscape-corridor and anchor rod are placed on the upper and middle parts of the pile structure, respectively. In virtue of the innovative structure, the ecological revetment will strengthen the revetment structure, reduce the revetment settlement, prevent the revetment from moving, and enhance the overall stability of the revetment project. The ecological holes exist on the ecological connecting-plates, which is beneficial to the exchange of material and energy from the river course and the bank slope, and the holes could greatly enhance the self-cleaning capacity of the water body. Not only do the plants on the ecological viewing-corridor provide the habitats for the organisms, but also green the revetment.

A reinforcement element for a diaphragm wall including a reinforcement cage, the reinforcement element further including a seal-carrier provided with a mounting part for receiving at least one seal, which is elongated, the seal-carrier being fixed to the first end part of the reinforcement cage and extending along the longitudinal direction of said reinforcement cage, the seal-carrier defining a housing for receiving the seal, at least a first part of which is surrounded by a sacrificial material.

A hybrid foundation structure includes a first perforation hole formed in the ground, at least one second perforation hole formed adjacent to the first perforation hole on a side surface of the first perforation hole, and a first pile and a second pile formed by mixing and injecting soil and soil solidifying agent into the first perforation hole and the second perforation hole.

The foundation system includes a below ground rigid raft foundation to bear a load for an above ground structure, and granular cushions and piles formed below the raft foundation. The granular cushions are configured for uniform load distribution of the raft foundation and the piles are configured to bear a load of the above ground structure and the raft foundation. The foundation system further includes stone columns encapsulated with a non-woven geofabric and configured to stabilize the raft foundation. The raft foundation is disposed adjacent and above the stone columns, the granular cushions are present between neighboring stone columns, and the granular cushions are present between the stone columns and the piles. The stone columns have a cementing agent for stabilization.

A tensionless concrete pier foundation for supporting a tower and a method of constructing the same is provided, the foundation having an outer CMP and an inner CMP with an annular space therebetween in which a plurality of sleeved tower anchor bolts are embedded, at least the outer CMP having an upper edge that is flush with the top of the foundation after the tower has been installed. A method of plumbing a tower anchor bolt cage using a bolt alignment ring is also provided that includes coupling the upper ends of the CMPs together with lateral spacing bolts that extend across the annular space. The tower anchor bolt cage is suspended from the lateral spacing bolts by the bolt alignment ring, and the lateral spacing bolts are shimmed on a low side as necessary for leveling the alignment ring and plumbing the bolt cage, before concrete pour.

Provided herein are various embodiments of retaining wall blocks suitable for use interchangeably as components in battered and vertical retaining wall construction. Each includes a block body and a vertical interlock system that includes: two female-type components comprising first and second grooves each extending along a bottom side of the block body and a male-type component extending across a top side of the block body. A lateral interlock system comprises a male-type lateral interlock interface integrated with a first side of the block body in lateral alignment with a female-type lateral interlock interface integrated with a second side of the block body. Methods for constructing retaining walls using the retaining wall blocks described herein are also provided.

The invention relates to a method of building a foundation (1) comprising a steel monopile (2) and a precast concrete part (3) on top of the monopile (2), comprising:—arranging a support structure (12) inside the monopile (2), the support structure (12) having a plurality of rods (16) extending radially with respect to a longitudinal axis of the monopile;—bringing the concrete part (3) above the monopile (2), with supporting columns (13) interposed between the support structure (12) and the concrete part (3), wherein reinforcement bars (14) protruding from a bottom surface (9) of the precast concrete part (3) extend downwardly beyond the support structure (12) by passing between the rods (16) of the support structure (12);—arranging tendons (15) between the support structure (12) and the concrete part (3) and tensioning the tendons (15); and—pouring concrete into an upper part of the monopile (2).
