Abstract:
A method for making substantially parallelepiped square cross-section formwork modules for building constructions, cut-off walls, embankments, dams, anti-erosion and anti-seismic foundations and/or the like, starting from used pneumatic tires, comprising at least the steps of: a) providing a used pneumatic tire deriving both from a periodic replacement of worn tires or from the rubber industry wastes or from the recovering of used pneumatic tires; b) removing from said pneumatic tire the two wall iron beads; c) performing cuts at diametrically opposite positions on the edges, said cuts defining cut-out regions separated by a middle solid region of the tire wall; d) removably mounting said pneumatic tire on basket-drum supporting means; e) pressing in diametrical directions towards a center of said pneumatic tire the pneumatic tire tread portions near said cuts thereby causing said tire to assume a substantially parallelepiped configuration, preferably of a square cross-section; f) pressing the corner regions of said substantially square configuration toward the center of said pneumatic tire and simultaneously continuing said pressing step thereby defining, at said cuts, hollow ribs of a substantially U-shape substantially extending through the overall width of said pneumatic tire, from a wall to the other wall of said pneumatic tire; g) providing a plurality of locking elements for locking the arms of each said rib and related connecting means; h) providing a corresponding plurality of substantially laminar flat upright elements; i) locking the arms of the U hollow rib of each said rib and simultaneously locking to each outer wall of each arm of said U of the two walls of each said rib a respective pair of said upright elements; I) introducing the pneumatic tire having assumed said substantially parallelepiped configuration, and supported by said supporting means, into a heating and/or cooking oven; m) withdrawing the pneumatic tire from said oven and cooling it to definitively fix said substantially parallelepiped configuration.
Abstract:
A system and method for long term storage of waste can include a comminuted material (100) having a high surface area. The comminuted material (100) can include particles of processed hydro carbonaceous materials from which hydrocarbon products have been derived. The comminuted material (100) can be contacted with a flowable waste material so that the flowable waste material is retained in the comminuted material (100). This flowable waste material is some material other than hydrocarbon products that have been derived from the hydro carbonaceous materials. An encapsulation barrier (105) can envelope the comminuted material (100) and provide a secondary means of preventing escape of the flowable waste material.
Abstract:
The method of the construction of passive foundation and, in particular, of connecting them with walls is characterised in that in order to improve the thermal insulation so as to limit the heat losses for a building or to simplify the structure or to reduce the building costs, the surface of the foundations or the contact surface of building materials/structural foundations (2) and building materials/structural walls (3) is purposefully reduced i.e. by being partly replaced with a column structure (made i.e. of reinforced concrete) (6) and partly with horizontal thermal insulation (7), whereas thermal insulation, which is an important objective of this operation, is placed under the walls of the building or between the foundation and the walls in places where the continuity of the foundations (walls) is limited/interrupted (between the columns). Horizontal insulation is therefore located under a considerable part of the walls, except for the surface of the poles.
Abstract:
A bipartite sensor array comprising two portions capable of assembly into a single sensory system. A first portion comprises rigid bodies connected by elongate flexures and fitted with gravimetric tilt sensors. The elongate flexures are capable of non-monotonic and non-constant bend in two degrees of freedom. A second portion comprised of rigid bodies connected by joints, contains the first portion. The second portion, which may be delivered and assembled separately from the first, provides rigidity and protection, enabling the first portion to have short rigid bodies and long connecting flexures, thereby reducing the number of sensors required. The bipartite sensor array is applicable to geotechnical measurements of soil and civil structures.
Abstract:
The present invention concerns a disposable formwork (1) for making ventilated loose stone foundations, in particular for floors, slabs, storage and/or collection tanks, dispersion tanks, alveolar concrete beds, cavities (4) and/or similar building structures, comprising: a body (3) having a first substantially convex surface (3a) intended to receive at least one binding material casting, optionally concrete, and a second surface (3b), facing the opposite side of the first surface (3a), substantially concave and suitable for delimiting, at least partly, a cavity (4); at least one support element (5), in particular four, having at least one contact portion (5a) arranged to engage a bottom surface of a cavity of a building structure under construction and arranged to support the body (3) according to a position spaced from the bottom surface of the cavity. The disposable formwork (1) comprises at least one portion made of polystyrene. Preferably, the entire structure of the disposable formwork is advantageously made of polystyrene.
Abstract:
Anti-earthquake building system comprising a first Groundwork (1) forming a rigid structure which transfers the fixed loads of said rigid structure and the loads of a mobile structure to the ground, a second Groundwork (2) forming said mobile structure on the first Groundwork (1), and a motion mechanism (3) that provides the second Groundwork (2) to be motile on the first Groundwork (1).
Abstract:
The present invention relates to the field of lining materials which are used to isolate landfill sites in order to avoid pollution of surrounding soil by ions such as heavy metals. In essence, the present invention discloses a process to increase the ion adsorption capacity of clay or dredged sediment. More specifically, the present invention discloses a process comprising: a) mixing said clay or dredged sediment with an anionic polymer, and b) subsequently drying said mixture, results in a lining material having superior ion adsorption characteristics.

Abstract:
The invention relates generally to the methods of soil / subsoil and groundwater protection from contamination by oil and petroleum products and particularly, to the methods of creation of protective hydrocarbon-impervious screens (barriers) under construction of oil storages, petroleum pipelines, sludge collectors and others. In a soil / subsoil solid impervious screens are formed which prevent downward migration of hydrophobic contaminants. This result is achieved by inserting into the upper (0-25 cm) soil layer natural mineral and organic sorbents followed by soil wetting up to the field capacity. Hereby the sorbents with high water retention ability are chosen. As mineral sorbents, zeolites, clays, and diatomites, and as organic sorbents peat, cellulose, lignin, sawdust, crushed bark, straw, rubber powder, and biomass of crop and wild plants, are used. The created barrier provides efficient retention of hydrophobic contaminants and does not disturb soil / subsoil water-physical properties.
