DE2364925A1 - Sinking building foundation components - by division and supplementing with mounting walls with lining walls directed against impact - Google Patents

Abstract

Building components are lowered in loose earth below the water table. The component to be lowered is first divided into component parts with one or more walls, and is supplemented with mounting walls to at least 2 floorless parts assemblies, which are lowered with lining walls, directed against impact; these are then joined together, and then the directly adjacent mounting walls are removed again, while a box-like group of components is retained. Preferably an underwater floor is fitted before the connection of the lining walls; the wall gap(s) and floor gap(s) are sealed, with jointing, and after pumping the components empty the corresp. mounting walls are drawn. Components can be sunk when their size or contour does not permit this as a unit.

Process and extension part for lowering structures in the course of the production of building structures in loose soils.

Addition to main patent P 2J 5o 808.9

The main patent relates to a method for lowering structures in the course of the production of building structures in looker floors, especially below the water table. The main patent is based on the task of specifying a lowering process, according to which a targeted and exact lowering of structures can be achieved regardless of the location of the groundwater level. This object is achieved by the invention according to the main patent in that first one or more injection anchors in required

Lowering direction into the subsoil, then the structure to be lowered is threaded onto the anchor rods of the injection anchors, then lowering presses working against the structure are connected to the anchor rods and finally the structure is pressed into the ground by means of the lowering presses. According to the teaching of the main patent, several injection anchors per building structure are used »The injection anchors are distributed along the line of the circumference or the length of the building structure in the • required lowering direction. The tie rods are led so far above ground and the starting point of the reduction as it required the height of the built up over the starting point building structure - the main patent gives as a result, lowering process at ₅ which in particularly cramped Baugrubenverhaltnissen ^, adjacent neighboring buildings in soft ground as Gravel,. Sand, silt, etc. can be dispensed with the creation of a construction pit and a special shoring as well as any additionally required building bracing. In addition, the lowering process according to the main patent can largely rule out a lowering of the groundwater and the consequent settlement in the neighborhood buildings that cannot be ruled out. Due to the buoyancy protection of construction pits and structures, which is connected at the same time with this lowering process, dewatering can be dispensed with or only a relaxation system will be required. This relieves the groundwater balance * the water rights of well operators are no longer affected and sewer and sewage treatment plants are no longer burdened.

The invention is based on the object ^ the lowering method to train according to the main patent so that building structures and have building constructions made from them, which are based on their size or floor plan do not allow a total lowering.

The invention relates to a method for lowering Structures in the course of the production of building structures in loose soils, in particular below the groundwater level, whereby first one or more injection anchors are introduced into the subsoil in the required lowering direction, then the The structure to be lowered is threaded onto the anchor rods of the injection anchor, then to the anchor rods against the structure working lowering presses are connected and finally the structure is pressed into the subsoil by means of the lowering presses becomes, according to the main patent. - The invention consists in that the structure to be lowered beforehand in single or multi-walled Expansion parts divided and supplemented by means of assembly walls to at least two bottomless kits and after lowering the construction sets with butt against butt, aligned expansion walls brought these together and then the immediately adjacent, parallel mounting walls while maintaining a box-shaped assembly can be removed again.

- According to the teaching of the invention, oversized structures or Building constructions from such structures in smaller auxiliary items divided and lowered to form box-like assemblies until the entire group has the size or plan shape of the actual building or the building structure to be created. This "then consists of a plurality single-walled or multi-walled extension parts located in a composite with one another, dispensing with the merely forming the box the auxiliary units required mounting walls. According to the teaching of the invention, components of any length can be produced or create area expansion, because there is no longer a total lowering depending on the floor plan of the building or building structures is required. Rather, there is, as it were, a breakdown into several construction phases or assemblies According to a preferred embodiment of the invention, the special one Significance especially in combination with the claimed dimensions

It is provided that an underwater floor is introduced before the expansion walls are connected, then the wall joint (s) and base joint (s) are sealed using composite production and the corresponding assembly walls are pulled after the construction kits have been pumped out ₀ The assembly walls take over the existing ones Construction walls not only support function to the forthcoming soil ^ but also enable a pumping dry the lowered expansion parts and the box-like modules made from them ^ so that gradually Einseiabsenkung can be made until the final structure or _0, the structural design is created "

Especially for tunnel construction ^ when parallel with a given Expansion walls arranged at a distance from one another are required, the invention provides that these excavation walls with in the area the base beams arranged on the mounting walls are lowered. The bottom beams then facilitate the introduction of the underwater bottom and the connection of the individual underwater bottom sections to one another ^ Because in principle it is provided that between the wall joints and base joints of the neighboring and one after the other an elastic or rigid connection is established for lowered extension parts · Recommended for elastic connections the invention, the wall and floor joints with elastic composite means or materials such as synthetic resin or bitumen, optionally with the interposition of bellows or Bellows hoses to be crimped. The bellows or bellows hoses can be inflated after the compression has taken place and create a particularly intimate and elastic bond between the individual external components. Looks at a rigid network the invention provides the wall and base joints with hardening composite means or materials, optionally with the interposition of grouting pipes to be grouted. There is also the

Possibility of grouting the wall and base joints after pumping out the building blocks.

The invention also relates to an extension part with rod guides embedded in concrete in the extension wall or walls, e.g. B. Pressure pipes for the injection anchor (s). This expansion part is characterized in that the expansion walls on their Butt surfaces have longitudinal grooves for receiving the bellows, bellows hoses or grouting pipes, so that in particular in the case the inclusion of bellows, bellows hoses with them preferably with an elliptical cross-section, engage in the longitudinal grooves of the adjacent extension walls «, in the case of the grouting tube receptacle one will provide this in one as well as in the other longitudinal groove of the adjacent expansion walls * Sin such The extension part is also characterized by base beams connected to the extension walls with longitudinal grooves to accommodate the bellows, Bellows hoses or injection pipes. In this way there can always be an uninterrupted elastic or rigid Realize the bond between the extension walls and the underwater floors of the extension parts lowered next to one another.

The advantages achieved by the invention are essentially to be seen in the fact that a lowering method is specified with the solo building structures or building structures can also be produced lengthways and flat, which due to their size or floor plan form do not allow a total lowering per se. The invention teaches the partial lowering of auxiliary units for Formation of assemblies and their assembly to form the structure that is actually to be lowered or the structure to be created from it Building construction. As a result, the lowering process can be implemented in a wide variety of ways according to the main patent.

the lowering press 6 is pressed into the subsoil 2. The structure 1 to be lowered is, however, previously divided into single-walled or multi-walled extension parts 7 and supplemented by means of mounting walls 8 to form at least two bottomless construction kits. After lowering the building blocks 7 * 8 with butt against butt directed expansion walls 9, these are brought into connection with one another and then the immediately adjacent assembly walls 8 arranged parallel to one another are removed again while maintaining a box-like assembly. The lowering progression can take place in the longitudinal direction as well as in the longitudinal and transverse direction, that is to say in the area spreading out. When the dissolved structure or structures are lowered below the groundwater level, an underwater base Io is introduced before the extension walls 9 of the extension parts 7 are connected, the wall joints 11 and base joints 12 are then sealed using composite production and, after the modules 7, 8 have been pumped out, the corresponding assembly walls 8 drawn. Extension walls 9, which are arranged at least in parallel at a predetermined distance from one another, as are preferably used in tunnel construction, are lowered with base beams 15 arranged in the region of the assembly walls 8. Both an elastic and a rigid bond can be produced between the wall joints 11 and base joints 12, that is to say in accordance with the physical conditions of the soil. In the case of an elastic composite, the wall and floor joints 11, 12 are made with elastic composite means l4 or materials, e.g. B. synthetic resins or bitumina, optionally with the interposition of bellows or Belgsohläuchen 15 pressed. In the case of a rigid composite, the wall and base joints 11, 12 are pressed with hardening composite means 14 or materials, optionally with the interposition of grouting pipes 16. It is also possible to re-press the wall and base joints 11, 12 after the construction kits ¹ J, 8 have been pumped out.
