Definitions
- Geosynthetic reinforced supporting structures and steep slopes represent composite bodies, which are formed from the elements filling floor, reinforcements and outer skin.
- the filling soil used is a shear-resistant, well-graded and compactable gravel sand.
- the reinforcements, which are enclosed by the filling floor, are made of high-tensile geosynthetics, mainly geogrids, fabrics and composites are used.
- the completion of the building on the air side forms the so-called outer skin.
- the composite body of filling floor and reinforcements is the actual supporting system that ensures the stability of the supporting structure.
- the outer skin is to be understood as a protection system, which has the task to protect the support system from the external influences and thus to ensure the long-term stability of the entire structure.
- a newer solution according to DE 10 2004 014 539 A1 is a system for constructing greenable supporting structures and steep slopes, comprising supporting, static and / or dynamic loads receiving and removing upholstery walls consisting of reinforcements made of high-strength geosynthetics and a compacted Filling floor, which surround the reinforcements known.
- One of these is structurally separate, spatially structured outer skin filled with undigested, greenable soil or building materials, which serves as a temporary abutment for the geosynthetic reinforcements when the system is erected, while the compaction of the individual filling soil layers absorbs the resulting earth pressure and permanently causes the protection of the cushion walls.
- the segments of the outer skin correspond in their vertical dimensions of the thickness of the layers to be installed and to be compacted the Greitz.
- the outer skin is layered.
- the segments of the outer skin are 40 cm high.
- the layers of the outer skin are usually staggered in relation to each other.
- the front element is designed as a rigid spatial grid structure, which may include a solidified greening structure. It is envisaged that the front element, but also the plastic spacers, which implies a proportion of renewable raw materials consists.
- the spacers are at the side where the back wall elements are applied and fastened, as these are concavely arched; on the side where the front elements are applied and fixed, the spacers have an inclination angle between 55 and 70 °.
- the rear wall elements are preferably made of decomposable material or natural fibers.
- the special shaping of the back wall of the outer skin substantially reduces the amount of vertical and horizontal changes in the shape of the support system by improving the flow of force in the geosynthetic reinforcements.
- the conditions for the greening are significantly improved. This is also helped by the fact that the strict separation of filling and culture soil allows the latter to be easily introduced.
- the segments of the outer skin allow their variable design in terms of inclination, height and lines, with the possibility to replace them in case of damage without affecting the stability of the support system.
- the object of the invention is to develop further application areas with a modified, sustainably simplified geometry of the rear wall.
- both the production cost of the system are reduced and its applicability to be expanded, so that a complex and economical construction system is created, with which the entire market spectrum for greener steep slopes can be covered with the most economical use of geosynthetics.
- the invention provides a bivalve component for the construction of greener formed of several layers steep slopes, which consists of a front element with rigid spatial lattice structure, a spacer element and a rear wall element. It is essential that the cross section of the permanently rigid rear wall element in the vertical direction follows a traverse or a straight line.
- the pressure-stable spacer is formed on at least one side by notches and has brackets for frictional connections with geosynthetics.
- At Abstandseiement at least two connecting means is attached to at least two points, with which the elements of the component are positively and non-positively connectable.
- the front, rear and rear wall element is made of plastic.
- the notches on the pressure-stable Abstandseiement are mounted in the installed state of the system on the upper side and stepped, whereby various inclinations of the steep slopes to be built are made possible; Consequently, horizontally different widths of berms can be designed.
- the holder for the frictional connection with the geosynthetics is mounted in the lower region of the spacers, and it is particularly advantageous to fasten them on a load-distributing rail.
- the connecting means with which the elements of the component are positively and non-positively connectable, are mounted on the Abstandseiement top and bottom. It is intended to releasably, preferably clip-like, design the connecting elements.
- the clam-shell component described above can be used as a stand-alone support system that permanently absorbs the horizontal effects caused by the earth pressure from the backfill.
- the plantable steep slope is formed by the stacking of the clam shell component.
- the clam-shell component is non-positively connected with horizontally and horizontally and horizontally and horizontally laid geosynthetics. It is also possible in accordance with the invention that the component is only connected in some layers of a multi-layer Operaböschung with geosynthetics.
- the most significant advantage of the invention is that the spatial outer, skin element, designed as a clam shell component, depending on the chosen use differentiated with geosynthetics can be combined. It can therefore be built greened steep slopes of all kinds with or without geosynthetics, depending on the practical application parameters, such as slope height, slope slope, static and dynamic effects, and the different application areas in construction, the most diverse system variants of plantable formed from several layers steep slopes are realized can.
- Fig. 1 shows the elements of the clam shell component and their design and their intended assembly.
- the bivalve component consists of the front element 1, the spacer element 2 and the rear wall element 3.
- the spacer element 2 has in the manner described the notches 4 and the connecting means 6.
- the cross section of the rear wall element is formed according to the invention in the vertical direction as a straight line.
- two spacer elements 2 and the rear wall element 3 are shown in addition to the front element 1, wherein the cross section of the permanently rigid rear wall element 3 is shown in the vertical direction as a polygonal line.
- the attachment of the holder 5 can be seen.
- 3 can be taken in cross section of the structure of a steep slope, which are stacked by the stacking 9 of four bivalve components, which are joined together horizontally depending on the length of the slope. It can be seen that as a result of the notches 4 at different depths, the berms 8.1 and 8.2 can be formed.
- FIGS. 4 and 5 it is shown that the bivalve component is connected to geosynthetics 7 either in every layer 10 or only in selected layers 11.
- the horizontally laid geosynthetics 7 can be used over the entire surface or even in strip form.
