An apparatus includes a monolithic retaining wall formed by combinable modular retaining wall blocks. Each of the combinable modular retaining wall blocks defines (A) vertical grooves extending along a vertical direction, and (B) horizontal grooves extending along a horizontal direction. This is done in such a way that the monolithic retaining wall, which is formed by the combinable modular retaining wall blocks, defines (A) spaced-apart instances of the vertical channels extending vertically through the monolithic retaining wall, and (B) spaced-apart instances of the horizontal channels extending horizontally through the monolithic retaining wall, in which at least some of the spaced-apart instances of the horizontal channels intersect at least some of the spaced-apart instances of the vertical channels.

A new civil infrastructure construction scheme is provided that is capable of meeting various objectives, including reducing climate change, addressing labor shortage issues, and enhancing construction productivity. Methods of forming load-bearing structures include placing a first reusable load-bearing element adjacent to a second reusable load-bearing element. The first reusable load-bearing element is fixed with respect to the second reusable load-bearing element without any adhesive or mortar. The first reusable load-bearing element and the second reusable load-bearing element respectively have a compressive strength of greater than or equal to about 25 MPa. The first and second reusable load-bearing elements optionally may be formed by additive manufacturing with a printable cementitious composition, such as an engineered cementitious composite.

Building blocks for mortarless brickwork and construction of houses, buildings, structures and hardscaping items are disclosed herein. According to the first variant the building block made in a form of polygon on each vertical and each horizontal face of which the response projections and recesses are made, coming into engagement with the projections and recesses of adjacent blocks. The projections and recesses are made in truncated cone form, along the axis of which in this block intercommunicating channels are made. According to the second variant on the faces of the building block only recesses are made in it in a form of cylinders and/or truncated cones, along the axis of which in the block the channels are made. At least, in some of the indicated recesses the fastening elements in a form of discs are installed, at both sides of which along the axe the bars, fixed in the indicated channels of the adjacent blocks are fastened. The invention allows to enlarge a range of possible variants of mutual blocks fastening.

A building block and a set of modular building elements is intended for construction of foundational and wall structures. The building block comprises a plurality of outer walls, a cavity, at least one inner wall, and at least two connecting elements. The outer walls are arranged in an n-gon shape surrounding the cavity and the cavity is open on both lower and upper sides. The cavity is divided by the inner wall into at least two parts. At least one part is adapted for the insertion of an insulating insert. Each connecting element is adapted for insertion into the cavity. The first connecting element is intended for insertion into the cavity of a different one of two neighbouring building blocks of a different row than the second connecting element. Each connecting element is attached to a wall of the building block and offset from that wall in a direction towards the inside of the cavity. Each connecting element comprises a wall of the connecting element protruding from a respective wall of the building block. The wall of the connecting element comprises a free end and side edges. The side edges approach each other from a place of attachment to the wall towards the free end. An insulating layer at least partially surrounds a part of the cavity adapted for the insertion of the insulating insert. The set of modular building elements comprises foundation building blocks comprising the cavity enclosed by the solid bottom and hollow building blocks.

The invention relates to modular elements for building a storage basin, to a network obtained by assembling a plurality of modular elements, to a supporting structure, to a storage basin and to a process for obtaining a storage basin. The modular element according to the invention is provided in the interior with a network element constituted by main half joints (10), secondary half joints (11) and tertiary half joints (10), vertical channels (8,15), oblique channels (9), compartments (18), and is provided with joint elements (16,17). The network comprises horizontal annular channels and main, secondary and tertiary joints connected by vertical and oblique channels. The storage basin comprises a supporting structure at the interior of an insulating structure obtained by assembling the modular elements. The process for obtaining a storage basin comprises the assemblage of the modular elements and casting the hardening material in the network obtained by assembling the modular elements, forming the supporting structure.

An arched building structure is provided having a foundation, an arch roof, a front wall, and a back wall. The arch roof is assembled from a rows of arches assembled from plurality of modular blocks. The rows of arches are interlocked with each other. The modular blocks include interlocking shapes and a fastening system.
