摘要:
Various monolithic pavers are one-piece pavers with no seams, joints, or connections. A monolithic paver can be formed via three dimensional (3D) printing or molding. The monolithic paver is designed to carry applied loads to paver support(s) via structural members of the monolithic paver. The monolithic paver is formed to include parallel structural members that are spaced with gaps there between. The parallel structural members include top flanges and webs. The parallel structural members can also include bottom flanges. Moreover, the monolithic paver can have exterior sides that have tongues and grooves formed there along; tongues can be formed along adjoining exterior sides of the monolithic paver.

A method of installing paving blocks comprises preparing an area to be paved to a desired grade. A preformed, load-bearing sheet of material, e.g., extruded polystyrene, is placed on the prepared area. Paving blocks are then laid in a desired pattern on the sheet of material.

An interlocking mat system including a plurality of individual mats configured to interlock together. Each of the plurality of individual mats has a top surface and a bottom surface. The top surface of each of the mats has ornamentation which simulates a desired texture, such as cobblestone, brick, or wood. The top surface also has a plurality of projections. The bottom surface of each of the mats has a plurality of channels which frictionally receive at least one of the projections from an adjacent mat. In one embodiment, the top surface of each of the mats also has at least one downwardly sloping graded edge, in order to prevent tripping over the mats. The interlocking mat system can be used to provide a customized driveway, walkway, or other similar area to provide a durable and resilient surface.

The disclosure discloses a hard pavement construction method for natural groundwater recharge, comprising the following steps: drilling to an underground shallow sand zone water storage layer on a flattened earth floor, filling holes with sand, inserting rod-shaped tools into the holes filled with the sand, pouring concrete to form a concrete foundation layer with a flat surface, removing the rod-shaped tools, filling the holes with the sand to be flush with a plane of the concrete foundation layer, sanding and compacting on the concrete foundation layer, directly arranging pavement bricks on a sand surface in an unbonded manner to form a hard pavement, and enabling rain and snow water on the hard pavement to pass through cracks of the pavement bricks, rapidly and naturally recharge to the underground shallow sand zone water storage layer via the holes and slowly permeate to an underground deep sand zone water storage layer.

A connection surface disposed on a face of a structural unit comprises a first segment having a three dimensional surface profile including a plurality of positive outer surfaces extending outwardly along a normal direction from a plane and a plurality of negative outer surfaces extending inwardly along the normal direction from the plane, wherein at least two of the plurality of positive outer surfaces are separated from one another along both vertical and horizontal directions and at least two of the plurality of negative outer surfaces are separated from one another along vertical and horizontal directions. A second segment opposes the first segment with respect to an axis, wherein the second segment is a substantial reflection of the first segment across the axis, but reversed along the normal direction.

An irregularly-shaped building unit includes a front surface, a rear surface opposite of the front surface, and an outer contour surface that extends generally perpendicularly from the front surface to the rear surface. The outer contour surface is irregularly shaped. A plurality of mating sides are disposed on the outer contour surface, where at least two mating sides intersect with a major axis, and at least two mating sides intersect with a minor axis. The major axis and the minor axis are generally perpendicular to each other. Each mating side is a centered rotation about the respective axis that the mating side intersects with.
