Definitions

  • the invention relates to a device for connecting sealing plates to be installed in a sealing wall, in particular a diaphragm wall for vertical sealing of landfills, preferably made of plastic, on their vertical side seams by means of coupling halves, preferably also made of plastic, arranged on adjacent sealing plates, which form a controllable cavity interlock positively and have a sealing strip which cooperates with the associated other coupling half in a sealing manner.
  • sealing plates made of plastic into the sealing wall, which act as an additional sealing layer, since the material of the sealing wall produced using binders or selective materials has a permeability that cannot be accepted, particularly when landfills are sealed.
  • these sealing plates In order to achieve the additional sealing by means of sealing plates to be installed in the sealing wall, these sealing plates must be connected to one another in a liquid-tight manner in their vertical side seams. In the known constructions, this is done by coupling halves arranged on adjacent sealing plates, which interlock in a form-fitting manner when the sealing plates are installed one after the other.
  • the two coupling halves form a cavity after assembly, which is made controllable to check the tightness of the connection of adjacent sealing plates.
  • the check can either be carried out only after assembly or continuously, with periodic or continuous checks being possible in the latter case.
  • the sealing walls are preferably produced using a supporting fluid which, when the sealing plates are assembled in sections, enters the cavity which is formed by joining the two coupling halves, it is necessary, after the respective installation of a further sealing plate, for the cavity of the supporting fluid formed by the coupling halves and to remove and clean any dirt.
  • the base of the cavity is first closed with a sealing material or a packer before the supporting liquid with the contaminants is removed from the cavity and the cavity can be cleaned.
  • the cavity is composed primarily of two tubular coupling halves.
  • the first coupling half has a larger diameter than the second coupling half and encloses it.
  • Each of the coupling halves, opposite their respective sealing plate, is provided with a slot, the slot of the larger coupling half being penetrated by the sealing wall connected to the smaller coupling half.
  • Sealing strips are formed on the outer circumferential surface of the inner coupling half, which, on the other hand, rest liquid-tight on the inner circumferential surface of the outer coupling half.
  • a disadvantage of the known construction is that, due to the considerable play of the inner coupling tube within the outer coupling tube, the sealing effect between the two coupling halves is not so good, in particular under the harsh conditions that after pumping out the support fluid and cleaning the Cavity penetration of support fluid is reliably prevented.
  • the support fluid penetrates precisely into the area between the interacting coupling halves which, according to the invention, is to be welded after cleaning.
  • Another disadvantage of the known design is that the cavity has only poor guiding properties when assembling the coupling halves and the two round profiles pushed into one another have only little resistance to tearing apart. The lack of guidance of the tools used later can also be regarded as a disadvantage.
  • the object of the invention is to provide, in a device of the type described for connecting sealing plates to be installed in a sealing wall, a design of the coupling halves which, after assembly, but before they are welded together, represents a sufficiently liquid-tight connection, the subsequent welding of which is liquid-tight seams results and brings the leadership properties that prevent tearing apart during assembly.
  • each coupling half is provided at its free edge with a cross-sectionally C-shaped end profile and in its edge connected to the sealing plate with a complementary to the C-shaped end profile and that at the transition between the recess and the sealing strips designed to form the cavity protrude into the cavity and can be welded to the transition between the C-shaped end profile and the wall forming the cavity of the associated other coupling half.
  • This inventive design of the coupling boy halves has the advantage that it can be used to create a sealing wall which enables safe assembly and which is sufficiently liquid-tight immediately after assembly to completely empty the cavity formed by the coupling halves and until the subsequent welding process to be able to protect against the ingress of support fluid.
  • the corners created by the shape serve to support and guide tools to be used in the interior of the cavity.
  • the in cross-section C-shaped end profile and the mirror-inverted recess form a labyrinth seal, which on the one hand cleans itself when the coupling halves are axially pushed together and which on the other hand forms an effective seal over a longer period of time, so that after emptying the cavity, no supporting fluid is left in can penetrate this cavity.
  • the sealing strip formed at the transition between the recess and the wall forming the cavity projects into the cavity, the latter is very easily accessible, as a result of which it can be cleaned reliably after the cavity has been emptied, together with the transition between the C-shaped end profile and the wall of the other coupling half forming the cavity. With this transition, the sealing strip is welded after cleaning. Since reliably cleanable and easily accessible parts of the coupling halves are welded together, liquid-tight weld seams are produced without the need to clean and / or clean the sealing surfaces necessary for the time between pumping out the cavity and the welding process, which are virtually inaccessible to be used for the welding process.
  • the proposal according to the invention results in a construction which, on the one hand, allows easy handling even under difficult practical conditions, in particular as far as the safe assembly is concerned, and on the other hand enables reliable sealing of the cavity with an improved process sequence.
  • Each coupling half is preferably provided with a web through which the coupling half can be welded to a hollow or full sealing plate.
  • the web is inserted into an intermediate space between two parallel plates, preferably made of plastic, and welded to these plates. This results in a two-shell sealing plate with coupling halves attached in a liquid-tight manner, the space formed between the plates being able to be formed in various ways.
  • the drawing shows two sealing plates 1, which are each formed by two parallel plates 2 made of plastic.
  • the space between these two plates 2 is filled with a cavity image, for example a grid 3.
  • the horizontal foot and head seam of each sealing plate 1 is sealed liquid-tight by extrusion welding.
  • each sealing plate 1 In the two vertical edges of each sealing plate 1, a web 4b of a coupling half 4 is inserted, which is also made of plastic as a profile. A cavity 5 is formed by the walls 4a of two interacting coupling halves 4, as can be seen in the drawing.
  • the sealing plates 1 and coupling halves 4 can also be made of metal, for example steel or aluminum.
  • a sealing strip 8 is formed on the inside of each coupling half 4, which protrudes obliquely into the cavity 5. In this way, both the surface of the sealing strip 8 and the surface of the adjacent transition between the wall 4a and the end profile 6 can be reliably cleaned. This ensures that in the subsequent connection, primarily by welding the sealing strip 8 to the opposite transition between the end profile 6 and the wall 4a of the other coupling half 4, a liquid-tight seam is generated which prevents liquids or pollutants from penetrating into the cavity 5 or even a passage of these liquids and pollutants in the coupling halves 4 reliably prevented.
  • the welding process is preferably carried out using a heating wedge guided through the angular shape of the cavity, which runs between the sealing strip 8 and the adjacent wall 4a and effects plasticization of the plastic before the sealing strip 8 is preferably pressed onto the adjacent transition between the end profile 6 and the wall 4a by means of pressure rollers becomes.
  • the subsequent and, if necessary, constant control of the cavity 5 can be carried out by overpressure or vacuum, by an indicator liquid, by checking the pH value by means of electrodes or other measures.
