Description

The inventions relate to a device of a joint-injection system according to the preamble of claim 1 and a corresponding method for the subsequent stabilization of water-permeable joint chamber cracks in bridges, tunnels and buildings according to the preamble of claim 14.

Undercrossing of WIB bridges and tunnels with mounting ceilings are highly endangered at temperatures above 0 ° C and smaller in concrete cracks across the joint chamber, by icicles and ice formation as well as long-term damage to the building fabric. Because the mounting ceilings consist in principle of loosely arranged side rails, which at a certain distance from each other are laid parallel and which rest on the raumabgrenzenden building end walls, wherein the longitudinal member spaces are filled by inserted, mostly hollow ceiling stones, so that a closed ceiling surface is formed. By pouring with mortar then construction-related unevenness be leveled evenly. In this case arise between the individual mounting elements such as the side members, the ceiling stones, the leveling mortar and the supporting wall only a frictional connection caused by contact forces and in some embodiments, between certain mounting elements, a mechanical clamping and through the mortar, there is still a certain adhesive connection. However, such compounds only satisfy the normally incurred attack loads and forces, ie purely static forces and very slight vibrations, as they occur in the so-called. Traffic loads for which the ceiling is designed.

The invention of the devices in question relates to a joint chamber injection system which can be formed with a micro-cable tube (joint-chamber microcable tube system) or a corresponding tube (joint-chamber injection tube system). For stabilizing cracks in and on concrete structures consisting of an elongated modified base body having at least one inner, longitudinal, bore-like recess and the outer wall of the base body, which has at least one longitudinal, groove-like recess for receiving a variable with respect to their volume insert. The invention will be explained with reference to the embodiment of the joint chamber microcable tube system, wherein the statements apply correspondingly also for the embodiment of a joint chamber injection tube system.

A seal of this type is known from DE-GM 84 25 518. It is designed as an injection hose. The tube made of rubber or plastic has a liquid-permeable wall. This wall has a slit extending over its length for the appearance of an injection liquid. In the wall, in the region of the slot, there is also provided a recess extending over its length for receiving a strip covering the slot, which consists of a material which changes the volume under the pressure of the injection liquid. The wall with the strips is enclosed by a tube of liquid-permeable material. This injection hose thus consists of three joined parts, which represent an elongated flexible structure. The aforementioned strip of compressible material is made of sponge rubber.

Comparable constructions show and describe the following documents: DE-GM 91 11 114 . DE-GM 83 00 766 . DE-OS 33 20 875 . DE-OS 34 00 654 . DE-OS 35 12 470 . DE-OS 41 23 067 . DE-OS 41 24 628 , EU-PS 199 108, DE 41 04 402 A1 . CH 462 420 A . DE 34 27 110 A1 . DE 43 40 845 A1 and EU-OS 501 004. If, for example, a concrete wall to be built on a concrete surface, a hose of the type mentioned above is placed on the concrete slab and fixed here, within that range, which is limited by the formwork for the wall to be built , The two ends of the hose are led to the outside. If the concrete is placed in the formwork for the wall and it is cured in the sequence, then an injection liquid is injected into the tube, which fills the joints between plate and wall seals. All these seals are built relatively expensive.

Also known are sealing materials made of plastic materials ( DE-OS 42 26 198 and DE-OS 42 26 385 ), which swell on contact with water and which are used for joint sealing or to compensate for dimensional changes in building construction, civil engineering and other technical areas.

From this material strips are made, for example, rectangular cross-section. In the construction of a masonry, as described above, such strips are placed and fixed on the concrete slab, within the formwork, which serves for the wall to be built. If such a sealing strip is laid in rainy weather, it will swell up before the concrete for the wall can be inserted into the formwork. If it reaches its maximum volume, then its sealing ability is questioned in the sequence. This seal is no longer accessible after completion of the wall.

For the sake of completeness, the seal for sealing pressed against each other end walls of precast concrete after the DE-OS 35 09 845 mentioned. The rubber profile used here has a triangular or circular cross section. This should be sealed columns between precast concrete, which have 30 to 90% of the height of the rubber profile. The CH-PS 542 965 describes a sealing profile of an elastic profile part and the elastic profile part temporarily biased holding rigid profile part, which is to be connected to the formwork. After insertion and after curing of the concrete, the formwork is removed with the attached rigid profile part, whereby the elastic profile part can relax. Seals of this type are not suitable for use in construction joints and also not suitable.

The object of the invention is to provide a reusable spring fleece-coated protection device against water leakage with an economic joint chamber / concrete crack injection system according to the type mentioned in the preamble of claim 1.

• Die erste abdichtende Funktion hat das Abdichtkissen mit Ventil, welches unter Druck das Quellvliesdichtband und/oder Abdichtsterne in die Zwischenräume presst.

The sealing effect is achieved by at least three functions:

• The first sealing function has the Abdichtkissen with valve, which presses the Quellvliesdichtband and / or Abdichtsterne in the interstices under pressure.

The second sealing function only becomes effective when water or chemical mixtures of pH ₂ , pH ₁₂ and / or approx. 80% gasoline, diesel, kerosene or paraffin oil mixture activate the swellable nonwoven. When water enters, the polymer embedded in the PP fleece swells up at the non-compressed sealing points and, thanks to its extremely dense, gel-like sealing layer embedded in the PP fleece, provides protection against water penetration during water ingress. After drying the gel layer, an overpressure with heat of ≥ 0.3 bar can escape through the Quelivlies, with new water ingress the polymer swells up again reliably.

The third sealing function comes into play when the / mentioned in the preamble of claim 1 Groove-injection micro-cable tube and accessories installed and sealed the Fugenkammer- / concrete cracks with injection means.

The device for the subsequent stabilization of water-permeable joints with concrete covers with interaction in trades should be universally suitable for a wide range of applications and meet by means of high notch, bursting pressure, chemical and water pressure resistance with a low weight from 850 g / m ² requirement, mechanically apply effective, elastic Flächenanpress- and / or water blocking pressure.

Furthermore, in the first function with the inflatable externally spring-fleece coated up to 50 m long device expansion joints in widths of 2 cm to 40 cm in a record time of about 10 min / m and in the second function with the gelling of an easily accessible place Without injection wells (structural damage) without special long-term road closure and without contamination are reliably and economically sealed.

In the third function, persons and property damage due to water penetration and conduction with consequences of icicle formation, smoothness formation and the building substance are to be reliably avoided temporarily.

• Fugenbleche,
• quellfähige Fugeneinlagen aus Gummi,
• Injektionsschlauch,
• Injektionsverpressungen,
• PUR-Gel Injektionsverpressungen

haben die bekannten Nachteile, dass die Abdichtungen unter Betriebs-bedingungen Setzungen, Scherungen und Dehnungen im Temperaturbereich -30° C bis +60° C unbeständig sind.The most popular Dehnfugenabdichtsysteme, namely

• Joint tapes made of rubber or bitumen,
• Seam joints,
• swellable joint inlays made of rubber,
• Injection hose,
• Injektionsverpressungen,
• PUR gel injection grouting

have the known disadvantages that the seals under operating conditions settlements, shearing and stretching in the temperature range -30 ° C to + 60 ° C are unstable.

Another disadvantage of injection grouting is a very high workload for injection wells that must be installed prior to injection grouting, which greatly affects the economics of the system.

The advantageous, final, the respective field of application corresponding modifications of the aforementioned basic component show the following descriptions.

When used as a water-barrier protection device for watertight sealing of expansion joints and / or expansion joints, the air-sealable sealing system (valve), preferably over the entire surface, enclosed with a swelling water-swellable sealing tape to achieve a complete water barrier to the joint flanks.

Depending on the type, for example 2 cm to 8 cm, 2 cm to 17 cm or 2 cm to 300 cm, the flat-tube cushion is laid longitudinally over joint offset points, bends and / or corners for a uniform and / or varying joint width and until it is filled with pressure PE (or equivalent) round cord sections secured.

The filling of the flat tube pad via a metal valve, which is connected to a welded-in the flat tube cushion extension. When inflating the flat hose cushion with air, the swelling fleece sealing strips are pressed into the interstices of joint chambers.

The disassembly of the reusable devices is easily possible by evacuation by vacuum pump or removing the valve core.

For sealing joints in lengths> 23 m, a second and further sealing pad is placed in the joint about 0.25 m to 1 m congruently with the first sealing pad so that tightness at the overlap is achieved.

The filling of the flat hose cushions is possible by first filling the longest sealing pad and then the shortest sealing pad to the desired filling pressure.

For sealing joints in arch bridges, sealing cushions are used in lengths of the radius of curvature. All sealing cushions are inserted congruently at the ends and approximately 0.25 m into the joints and secured with a PE round cord to the pressure filling.
