A formwork element for a molded wall panel end, comprising: a sole plate having a first lateral edge, a second lateral edge, an outer face, an inner face bearing a caisson, said caisson leaving free, on the inner face of the sole plate, a first lateral zone, defined between the first lateral edge and the caisson, and a second lateral zone, defined between the second lateral edge and the caisson; a form stripping assistance device cooperating with the sole plate. The form stripping assistance device includes at least one first sacrificial section comprising a first portion disposed on the first lateral zone of the inner face of the sole plate.

Disclosed is a foundation unit for supporting a structure, the foundation unit provided in a plurality of parts, arranged to be coupled together before use, wherein the foundation unit is arranged to be at least partially buried in, and to receive, material.

Systems and methods to provide pressed aggregate-filled cavities for improving ground stiffness and uniformity are disclosed. According to an aspect, a method includes using a mechanism to press into a ground surface in a substantially downward direction to create a concavity. The method also includes substantially or completely filling the concavity with unstabilized or chemically stabilized aggregate, soil, or sand. Further, the method includes using the mechanism to press the aggregate within the concavity to achieve a desired ground stiffness.

The present application discloses a construction method for pouring concrete in a karst cave. Concrete streaming is pumped into a hollow passage of a drill stem, then opens the one-way openable sealing cover with a pre-tensioned spring on a reaming drill bit and enters the karst cave to complete pouring of the concrete. When the karst cave is relatively low, low-slump plain concrete mixed with quick-setting agents is injected through a drilling rig and the hollow drill stem to form a concrete pier; when the karst cave is relatively high, the hollow drill stem is sleeved into a thin-walled steel shell, and the thin-walled steel shell is synchronously sunk into the drilled hole while drilling, enters the karst cave and is socketed into a stable rock stratum, then concrete is pumped into the thin-walled steel shell from the bottom of the pile, and finally, a reinforcement cage is inserted to form a cast-in-place pile. Compared with the existing karst cave treatment methods, the construction method according to the present application can greatly reduce the consumption of materials, improve the mechanization of construction, simplify the construction process, shorten the construction period and reduce the engineering cost, and the cast-in-place pile with thin-walled steel shell, formed when the karst cave is relatively high, can further improve the bearing capacity of the foundation.

Embodiments described herein relate to construction of subsurface structural elements that are configured to redirect soil forces. For instance, a form may be used to construct a subsurface structural element such that the subsurface structural element redirects soil forces to vertically displace a foundation rather than have the soil forces crack or otherwise damage the foundation.

A method of constructing multiple conduits in building foundations that eliminates the process of core drilling after the foundation has been poured and set. This method creates optional openings for possible future connections. The process uses removable conduit molds installed before the foundation is poured. Once the foundation has set, conduit molds are removed to explose conduits in the foundation as needed.

A foundation for an offshore structure, more particularly an offshore wind turbine structure, comprising: at least one tower-like foundation structure with a circumferential foundation wall extending in the longitudinal direction, the foundation wall being delimited at the lower end by a lower-end end face, the foundation wall being formed from a mineral construction material; and at least one binding element, which is formed from a metal material and is arranged on the lower-end end face, the length of the binding element from the lower-end end face to a lower end of the binding element being at least 0.5 m.

A method of constructing a building is disclosed, including selecting a standard dimension less than a wide-load trucking permit limit and designing a building on a grid defined by the selected standard dimension. The building includes a plurality of prefabricated elements, wherein each prefabricated element has a width correspond to the selected standard dimension. The plurality of prefabricated elements includes a wall panel, a roof panel, a laterally resistive frame, and a rebar cage. The method includes fabricating each of the plurality of prefabricated elements at a manufacturing plant and transporting the elements by truck to a building site. The method includes constructing intersecting grade beam footings at the building site and pouring a slab between the intersecting grade beam footings. The grade beam footings include the rebar cage and have a uniform width and depth, the grade beam footings and the slab having contiguous upper surfaces.

A method of constructing multiple conduits in building foundations that eliminates the process of core drilling after the foundation has been poured and set.

Once the foundation has set, conduit molds are removed to explose conduits in the foundation as needed.

A method for constructing a seawall section includes coupling an end of a substantially-waterproof barrier member to a footing. A concrete form is mounted to the footing such that a top end of the form is higher than an exposed upper surface of the footing. The concrete form defines at least part of a fill volume. Another end of the barrier member is coupled to the concrete form such that the barrier member extends over a side of the concrete form opposite the fill volume. Concrete is then poured into the fill volume and cured to form the seawall section. Prior to the curing, a body of water at the footing may be higher than the upper surface of the footing. However, the barrier member prevents water from entering the fill volume through the concrete form.
