Definitions

  • the invention relates to a method for shutting off moisture rising in masonry according to the preamble of claim 1.
  • Such a method is known from DE-OS 33 18 132.
  • the holes drilled side by side to renovate the masonry completely penetrate the masonry to be renovated and can be arranged horizontally or at an angle.
  • the boreholes are produced with a drilling tool, which consists of a number of drilling tools arranged next to one another and spaced apart from one another, so that a corresponding number of drilling holes is produced simultaneously with a single drilling operation. After a drilling operation has been carried out, the drilling tool is laterally displaced by a distance which is somewhat smaller than the diameter of a drilling tool.
  • the individual adjacent boreholes are at a distance from one another which is somewhat smaller than the diameter of the drilling tools, so that a continuous slot results from a multiplicity of boreholes in the masonry.
  • the slurry is filled directly into the drilled holes forming the slot. After curing, the slurry forms a coherent layer. On the one hand, this layer has the function of forming a barrier against the rising moisture in the masonry. On the other hand, this layer, when cured, must be able to bear the entire load of the structure above it.
  • the disadvantage here is that the slot formed by the boreholes must be sealed at least on one side of the masonry over its entire cross-sectional area before the sludge can be introduced.
  • the slot formed by the boreholes must be sealed at least on one side of the masonry over its entire cross-sectional area before the sludge can be introduced.
  • a fully filled slot is necessary for static reasons.
  • the demands placed on the sludge are also high. Insufficient strength of the sludge would damage the structure, and sludge with insufficient moisture barrier properties would undermine the success of the renovation measure.
  • the object of the invention is to improve a method of the type mentioned at the outset in such a way that the introduction of the sludge is simplified, the moisture barrier effect is improved and, at the same time, the necessary load-bearing capacity of the barrier layer is reliably achieved.
  • the elongated elements can easily be produced in any length, for example by extrusion, and can also be cut to the correct length on site in accordance with the wall thickness of the masonry to be renovated. Because the extension has a cross-section adapted to the cross section of the connecting cavity, it is easily possible to insert the extension of an elongated element into the at least one connecting cavity of a second elongated element, so that a connection results between the two adjacent elements.
  • the connection of elongated elements can be repeated as often as required, which results in a flat structure from a large number of elongated elements connected to one another. This flat structure forms a barrier in the masonry to be renovated in a simple and advantageous manner.
  • An elongated element is inserted into the individual boreholes, the cross section of which is expediently adapted to the cross section of the elongated element, a second elongated element with its attachment being inserted into the at least one connecting cavity of a first elongated element.
  • the central cavity is used for receiving and transferring the sludge, which, for. B. can be a plastic or the like., And which can set relatively quickly, the slurry or the plastic or the like.
  • the sludge which, for. B. can be a plastic or the like.
  • the moisture rising in the masonry is reliably shut off since the flat structure formed from the elongated elements already acts as a moisture barrier and an additional moisture barrier is formed by the sludge. It is favorable that the elongated elements are embedded in the grouting slurry.
  • a hollow diamond drill is expediently used as the drilling tool, because with such a drill any masonry can be drilled through easily and without vibration.
  • the holes are arranged in the regions of the outer circumferential surface of the elongate element located between the extension and the at least one connecting cavity. Such an arrangement of the holes ensures that the sludge pressed into the central cavity or that into the central cavity Cavity pressed-in plastic, which sets and cures at normal temperatures, fills both the one and the opposite second gap between an elongated element and the borehole wall, ie both gaps, which are delimited by the connecting area between the lugs and the elongated elements.
  • the central cavity, the at least one connecting cavity and the extension preferably extend over the entire length of the elongate element.
  • Such a device is simple to manufacture, for example in an extrusion process, in any length and can simply be cut off on site to the length corresponding to the wall thickness to be renovated with regard to its wall thickness.
  • the formation of the extension in the length corresponding to the longitudinal element results in a barrier between adjacent elongated elements which cannot be overcome by the moisture in the lower part of a masonry or a foundation masonry.
  • the elongated element can have any cross section. For example, it can have a rectangular cross section. However, it is advantageous if the elongate element has a circular cross section and the attachment is formed on the outer lateral surface of the elongate element by means of a web.
  • An elongated element with a circular cross-section has the particular advantage that the holes in the masonry to be renovated can be adapted comparatively precisely to the cross-section of the elongated elements, so that the space between the elongated element and the wall of the hole in the masonry can be kept small . As a result, the material consumption for filling this space is low.
  • the sludge can contain chemical agents that result in silicification in the masonry to be renovated.
  • the extension and a connecting cavity of the elongate element are preferably arranged diametrically opposite one another.
  • Such a configuration of the elongated element makes it possible to arrange a plurality of such elements next to one another in one plane or slightly inclined or curved in relation to this plane, because the extension of an elongated element in the connecting cavity of the adjacent element can also be pivoted.
  • the gap provided in the longitudinal direction of the elongate element, which connects the connecting cavity to the outer surface of the elongate element is somewhat wider than the web connecting the extension to the outer surface of the elongate element.
  • the elongate element has, in addition to the central cavity, a shoulder and three connecting cavities which are uniform around the outer surface of the elongate element, i.e. H. offset by 90 °, are distributed.
  • a shoulder and three connecting cavities which are uniform around the outer surface of the elongate element, i.e. H. offset by 90 °, are distributed.
  • the elongated element can have at least one sealing member that closes the end of the central cavity.
  • a sealing member can be attached on site to one end face of the central cavity of the element, after which it is easily possible to insert a z in the central cavity from the opposite, second side.
  • the elongate element prefferably has two sealing members which close off the central cavity on both end faces, the sealing member on the second end face being provided with a through-bore and a connecting part for introducing the sludge.
  • the first-mentioned sealing member serves to seal the central cavity of the elongate element on one side.
  • the second sealing member on the opposite end face of the central cavity serves to allow a slurry or a plastic to be pressed through the through hole.
  • the connection part is used, for example in the form of a nipple, for connection to a hose line which is connected to a container containing the sludge or the plastic.
  • the sealing members have circumferential ribs for sealing the central cavity of an elongate element. These circumferential ribs bend when the sealing member is inserted into the central cavity in such a way that even in the case of a relatively high pressure in the central cavity, such as results from the sludge or the plastic pressed in, it does not bend into the opposite direction can switch opposite direction. Rather, the circumferential ribs spread out more and more the higher the pressure in the central cavity, so that there is advantageously good sealing of the two opposite end faces of the elongate element at all times.
  • the method according to the invention can also be applied to foundation masonry, pillars, abutments or the like.
  • FIG. 1 shows an elongated element 12 for shutting off the moisture rising in masonry, which has a central cavity 14, a connecting cavity 16 and an extension 20 on its outer surface 18.
  • the central cavity 14 in the elongated element 12 is connected to the outer lateral surface 18 of the elongated element 12 by means of holes 22.
  • the connecting cavity 16, which extends in the longitudinal direction of the elongated element 12, is connected to the outer lateral surface 18 of the elongated element 12 by means of a gap 24 provided in the longitudinal direction of the elongated element 12.
  • the projection 20 has a cross section that is adapted to the cross section of the connecting cavity 16.
  • the central cavity 14, the connecting cavity 16 and the extension 20 extend over the entire length of the elongated element 12.
  • the holes 22 are present both in one and in the other of the two areas of the outer lateral surface 18 of the elongate element 12 given by the extension 20 and the connecting cavity 16. With this design, the entire gap remaining between an elongated element 12 and the wall of the masonry is connected to the central cavity 14, so that a slurry or the like pressed into the central cavity 14 flows out through the holes 22 and completely fills the latter gap can.
  • the elongated element 12 has a circular cross section and the extension 20 is integrally formed on the outer lateral surface 18 of the elongated element 12 by means of a web 26.
  • the web 26 preferably has a wall thickness that is somewhat smaller than the width of the gap 24 connecting the outer circumferential surface 18 to the connecting cavity 16.
  • Such a design of the web 26 and the gap 24 makes it possible to have adjacent and interconnected elements 12 to be arranged both in a plane and in a curved surface, without impairing the moisture barrier effect of the flat structure resulting from the connected elements.
  • the projections 20 and the connecting cavity 16 are arranged diametrically opposite one another. With such a design it is possible - as stated above - to connect adjacent and interconnected elements 12 in one plane and also along a curved surface.
  • the connection of adjacent elements 12 takes place in that the extension 20 of an element 12 is inserted into the connection cavity 16 of an adjacent element 12.
  • the web 26 is somewhat thinner than the gap 24 and the inside of the connecting cavity 16 is slightly larger than that Cross-sectional dimensions of approach 20.
  • Figures 2 and 3 differ only in the arrangement of the holes 22 in relation to the central cavity 14 or in relation to the outer surface 18 of the elongated element 12.
  • FIG. 4 shows a cross section through an elongated element 12 for shutting off the moisture rising in a masonry, which has a central cavity 14, three connecting cavities 16 and an extension 20 on its outer surface 18.
  • the central cavity 14 is connected to the outer lateral surface 18 of the elongate element 12 by means of holes 22.
  • Each of the connecting cavities 16, which each form a right angle with one another, is connected to the outer circumferential surface 18 of the elongate element 12 by means of a gap 24 which extends in the longitudinal direction of the elongate element 12.
  • the extension 20 has a cross section which is adapted to the cross section of the three connecting cavities 16 or is somewhat smaller.
  • FIG. 5 shows a section of a masonry 28 to be renovated, into which boreholes 30 are drilled next to each other. Holes 30 have a distance from one another which is somewhat smaller than the diameter of the boreholes 30. In this way, a continuous slot results in the masonry 28, an elongated element 12 being inserted into each borehole 30.
  • the elongated elements 12 with a circular cross section preferably have a somewhat smaller diameter than the boreholes 30, so that there is a gap-shaped intermediate space 32 between the wall of the boreholes 30 and the outer circumferential surface 18 of the elongated elements 12.
  • the bores 30 are through bores through the masonry 28 to be renovated.
  • the elements 12 have a length corresponding to the wall thickness of the masonry 28 to be renovated, ie they extend through the bores 30. 5 shows the connection of two adjacent elements 12 particularly clearly.
  • the second element with its connecting cavity 16 is pushed onto the extension 20 of the first element 12.
  • the central cavity 14 of the elongated elements 12 is closed off on at least one end face by a sealing member 36.
  • the gap-shaped intermediate space 32 remaining between the bores 30 and the outer lateral surfaces 18 is sealed at the end regions of the elongated elements 12, for example by means of a rapidly setting compound.
  • a slurry containing chemical active substances e.g. B. a hardening plastic or the like.
  • the renovated masonry 28 again has good static strength and a good moisture barrier, since both the elements 12 and the sludges filling the central cavities 14, the holes 22 and the gap-shaped spaces 32 act as a moisture barrier.
  • elongated elements are repeatedly inserted into the boreholes in the masonry to be renovated, the outside diameter of which is precisely adapted to the borehole diameter.
  • These last-mentioned elements act as wedges for supporting the pierced masonry and, moreover, they serve to delimit an area which is covered with a slurry, a plastic or the like. is filled in as described above. In this way, the individual borehole regions, delimited by the elongate elements acting as wedges, can be covered with a binding material of the. the type described above are pressed and the drilling work can be continued at the same time in the masonry.
  • the elongated elements acting as wedges can also be designed without a central cavity.
