Definitions
- the invention relates to a method for isolating parts of buildings and / or Devices, in particular for performing moisture insulation and Improve the statics.
- Parts of the building and here in particular are parts of the building lying underground and installations in contact with the earth through moisture insulation before the entry of Groundwater, earth moisture and / or through seeping rainwater Protect moisture damage.
- the parts of the building lying underground with an outer insulating layer, for example from bitumen or other non-rotting and moisture-insulating Materials.
- Both the edge area of the floor base plate respectively are made with the aforementioned materials coated. The coating can be done by applying a thick betumen coating respectively.
- the invention has for its object to show a novel method, which is a subsequent, completely sealing insulation of the underground components of the building.
- the particularly advantageous method according to the invention is characterized by this from that the inclusion of the surrounding soil and / or filler is used for sealing, wherein a hardening substance under pressure in the soil and / or the filling material is pressed.
- a seal is not in the existing masonry or concrete work made, but it becomes a additional sealing protective layer outside the existing building in the Soil or the existing filling materials.
- an insulating protective layer to be provided below the base plate, which in particular before protects penetrating groundwater from the soil area.
- the one to be brought in Protective layer can pass the floor slab past the vertical walls can be raised to a height that provides adequate moisture protection guaranteed, the vertical expansion corresponding to the measured groundwater levels can be adjusted so that a adequate protection against oscillating water levels is guaranteed.
- the inventive method is particularly suitable for those areas due to dammed rivers, flood areas or through other regional changes to increase the groundwater level to lead.
- a peculiarity of the process is that through training the protective layer outside the building components an improvement of the Statics is possible in the first place and for the occurring horizontal loads the water pressure is strengthened, which makes the process particularly suitable for oscillating water levels with increased water pressure from the outside.
- Further Advantages result from the fact that the base plate is included in the sealing measure can be included and improve the static Resilience and the absorption of horizontal loads.
- the Protective layer an increased loads due to horizontal loads and possible static weaknesses of the building compared to the pressure fluctuations that occur to be caught.
- the protective layer is a further embodiment of the method provided that the injected substance has sufficient moisture Amount is supplied or that the substance with a sufficient amount of moisture is enriched or that the injected substance with the im Soil or filler material at least partially reacts and hardens.
- the Introducing the substance from outside or from inside the building and / or facilities is suitable especially with smaller underground parts of buildings, facilities or at leaking pipes, for example drainage channels, whereas, for other walk-in buildings, this is preferred.
- the substance is introduced through boreholes from the inside.
- the substance in several successive operations is pressed in, at least partially between the operations Curing can be waited for.
- the substance is preferably injected through an injection lance fed to the soil or filler under pressure.
- Layer thickness of the insulation made in the form that first to Insert the injection lance into the walls several spaced drill holes and / or the floor area of the building is drilled after drilling a first injection of the substance in the immediate vicinity of the outer layer or insulating layer of the building and after curing the Drill holes are expanded to a necessary increased drilling depth, one second or further injections of the substance behind the one that has already hardened vault-like layer takes place and the work steps successively as long are repeated until a desired depth of 30 to approx. 200 cm is reached has been.
- the drill holes can be arranged horizontally, vertically or inclined to the horizontal, so that the tip of the injection lance can be guided both into the lateral layers of earth and under the base plate and can be adjusted in the respective depth.
- the substance is preferably pressed in with sufficient pressure so that it can be pressed in not only in the immediate vicinity of the lance tip, but also over a wide area. This means that only a few boreholes are necessary and an efficient way of working is possible.
- a plurality of injection lances can be produced at the same time or, if necessary because of the delayed hardening with an injection lance, a surface-covering insulating layer which combines to form a uniform, vault-like protective layer.
- the vault-like layers lying side by side and one behind the other thus combine to form a stable and self-contained sealing protective cover, which encloses the underground building components and thus prevents the penetration of moisture.
- this protective layer absorbs all or part of the horizontal forces generated by earth pressure and / or hydrostatic pressure.
- a cement or a cement mixture with a fineness of 3,500 to 20,000 Blaine (cm 2 / g) is preferably used as the substance, which, if necessary, ensures adequate moisture insulation by chemical additives.
- the fineness of the cement or cement mixture ensures in particular that the substance injected by the injection lances can penetrate deep into the pore space of the soil or filler material and thus forms a large, vault-like layer around the tip of the lance.
- it is necessary for the filling material or soil it is necessary for the filling material or soil to have a suitable grain size, which can combine with the injected cement to form a concrete-like mass.
- Quality assurance measures an ongoing and / or subsequent control the substance injection is carried out.
- a georadar is used which is used during or after the completion of the injection process is used to analyze the floor area and thus a control about the existing depth of penetration and spread of the substance in the soil or filler material.
- a layer thickness of approx. 30 to 200 cm can thus be built up, which is manufactured in a controlled process.
- a seismic method which is also a local determination of the layer thickness and spread of the Protective layer enables.
- control means such as rods be introduced, which control the spread of the injected substance enable.
- the control rods are made by the hardening and spreading Press the substance back inside the existing holes and leave Detect the areas to which the pressing takes place as soon as you inject is.
- a particular advantage of the method according to the invention is that the Layer thickness can be adapted to the respective requirements and due the fineness of the cement used, a waterproof concrete layer arises, which penetrates moisture into the basement through the retrofitted concrete tub prevented or except for a harmless Dimension reduced, whereby the concrete trough not only over the side masonry, but can extend partially or completely to below the base plate.
- FIG. 1 shows the lower area of a building 1, with one in the ground 2 lying basement 3.
- the basement 3 consists of a base plate 4 and side walls 5 and a ceiling 6, which simultaneously the floor of the ground floor.
- an irregularly shaped protective layer 7 with a thickness of approx. 30-200 cm trained, which protects the basement 3 against the ingress of moisture.
- Base plate 4 holes 8,9 introduced through which a not shown Injection lance can be inserted to inject the substance.
- the Injection lances to a depth of, for example, 2 m into the surrounding Soil 2 can be inserted in order to inject the substance kick off.
- the lances are to the intended depth inserted and withdrawn from the holes 8.9 after the injection pulled out.
- an injection first in the immediate vicinity of the basement 3 and at least one partial hardening of the protective layer 7 is waited for before by deeper The substance is injected again using the injection lance.
- the advantages of the method are that the area below the Base plate 4 can be included in the insulation and by Formation of a vault-like protective layer 7 an improvement in the statics is made so that the basement 3 also higher horizontal loads can record.
- Figure 2 shows an enlarged view of a corner area of the basement 3 according to FIG. 1.
- the protective layer 7 extends below the base plate and possibly to the old one Insulation 10 of the basement 3 can be brought up.
- Spreading the protective layer 7 can be checked continuously or subsequently substance injection is checked, whereby in the case of weak points it is easily possible to re-drill through a new hole Perform injection.
