Definitions

  • the present invention relates to a concrete compressible concrete based on cement or synthetic resin, hereinafter referred to as "compression concrete” or referred to by the abbreviation "DKB", and to a method for its production.
  • compression concrete or referred to by the abbreviation "DKB”
  • the upsetting concrete DKB according to the invention can be used for multiple, very different fields of application in civil engineering, see section (010). Its strength is in the range of normal concretes, and it is characterized by its specific, precisely defined load-deformation behavior (diagram Fig. 1) and by its high ductile (plastic) deformability: Under increasing load increases from reaching a certain, by the choice of Formulation specified compressive stress
  • Fatigue state is reached and the resistance again corresponds approximately to that of a rigid body.
  • the DKB compression concrete is composed as follows: Aggregates:
  • Thick-walled plastic tube (4) made of PP / HDPE, for cylindrical compression bodies,
  • Composition and structure of the compression bodies between 0.4 and 0.5 (40 or 50%).
  • Shotcrete with addition of tubular steel hollow bodies according to the invention in size suitable for the process can be compressed by about 8% to 15% or more without increasing the load beyond the ultimate strength. Such a compression rate can be considered sufficient to intercept the critical rock movements to be expected when driving on a tunnel in difficult terrain.
  • the DKB compression concrete is particularly suitable for
  • SB foaming agents
  • a newer patent from HOCHTIEF describes a "damper concrete” or “special concrete” with the addition of polystyrene beads in different proportions, which serves, for example, as impact protection for fuel rods (castor technology) during critical transfer phases. According to the intended use, this concrete has a limit strength of 5 MPa.
  • the admixture of expanded clay lenses or foam chunks is known as a "plasticizer” for concretes.
  • the boundary strength would drop to values well below one tenth of the pure mortar strength, to explain that after reaching the limit strength, the cement matrix collapses and the carriers of the Air pores do not have their own strength. This also results in the characteristic, inevitable collapse of the deformation resistance after reaching the limit strength.
  • the limit strengths which can obviously be achieved with cement as a binder are generally several times higher, up to a factor of about 10, than those of DKB compression-hardened concrete; for higher values, plastics are expected to be used as binders at significantly higher costs.
  • steel foam is a very expensive high-tech product, and it can be doubted whether this is technically feasible in quantities required for practical tunneling.
  • the production of the tubular steel hollow body of the DKB edged concrete is preferably carried out with the aid of a device as described below (FIG. 7):
  • the device preferably has two pairs of rollers synchronized with one another, which face each other - comparable to the "rolling stands" in FIG
  • the starting material preferably tubes in ⁇ m-Liefer GmbH
  • the first pair of rollers with cams at a distance of the later hollow body lengths (circumference) is occupied and serves the squeezing (flattening) of the tube in the predetermined intervals
  • the second, running in common mode roller pair is equipped with mutually working shear blades in the same intervals and the hollow body in a continuous process separates.
  • tubular steel hollow bodies in dimensions suitable for the method as an integral part of shotcrete formulations, especially for underground mining, such that the shotcrete can be compressed in a controlled manner as described in section (007) without losing its supporting function for securing the cavity .
  • FIGS. 4 and 5 shows a horizontal section through a DKB compression body analogous to FIGS. 4 and 5 with an upstream intermediate piece, but additionally equipped with a vertically arranged wedge pair,
  • Fig. 7 is a side view of the machine for producing the tubular steel hollow body according to the invention.
  • a preferred embodiment of the upsetting bodies (3) is the cylindrical shape shown in Figs. 2 to 6 enclosed by a reinforced concrete coil (2) in combination with a high elongation plastic outer tube (4).
  • the plunger preferably a concrete-filled steel pipe
  • the plunger is shown, its use in an initial partial load of the compression body (3) and thus, where desired, to a load-deformation line with a low initial value and Increasing the deformation resistance with increasing compression leads to the full “plateau value". This can be the case, in particular, when the compression bodies are installed in a horizontal position and are unloaded in the normal state. So a "softer buffering" of the building is achieved.
  • the dashed line (6) represents the imaginary boundary line of the load radiation in the compression body (3).
  • the wedges must have a defined coefficient of friction in the sliding surfaces (9) and may only have an inclination at which the self-locking is still ensured.
  • a mechanical or pneumatic spring (10) support and accelerate the movement (9) of the wedge (8) into the resulting gap.
  • the apparatus shown in Fig. 7 for producing the tubular steel hollow body according to the invention consists essentially of two mounted in a common frame, mutually synchronized, opposing pairs of rollers.
  • the first pair of rollers (13) in the direction of passage (9) is fitted at predetermined intervals with cams (14) which precisely flatten the inserted tube precursor (15) at the points where the second roller pair (16), in turn, is equipped with the cutting jaws (17), the finished hollow body in a continuous process separates.

Abstract

Le béton compressible (DKB) défini dans l'invention, présente une courbe de déformation sous charge, caractéristique avec un plateau de fluidité caractéristique, et contient en tant que liant, du mortier de ciment ou de résine époxyde, et en tant que substances d'addition, des sections courtes ou longues de tubes d'acier d'usage dans le commerce (corps creux de tube d'acier) ayant des diamètres de l'ordre du millimètre au décimètre et étant refermés aux deux extrémités de façon étanche au mortier, de préférence par pincement ou par aplatissement. La production des corps creux de tube d'acier s'effectue dans le cadre d'un procédé continu sur une machine comprenant des paires de cylindres à mouvement synchrone, pour réaliser l'aplatissement ponctuel des tubes et la séparation des corps creux. L'invention s'applique par exemple entre autres : au creusement de roche et de tunnels dans des montagnes sous pression ; au montage de ponts avec amortissement horizontal et vertical, à des réservoirs à liquide, à des constructions de récupération d'énergie (nucléaire) etc. dans des zones exposées aux tremblements de terre, à la protection de constructions contre les corps explosifs, à la protection de constructions contre la collision de véhicules, à la compensation (à l'évitement) de différences d'affaissement dans des fondations sur pilotis.
