Description

TECHNICAL AREA
The invention relates to a retaining wall of retaining wall elements, wherein the retaining wall elements comprise a wall body with a support side. Furthermore, the invention relates to a method for creating a retaining wall and the use of retaining wall elements.
STATE OF THE ART
CH 676 015 describes a retaining wall construction for securing backfills with an outer skin forming wall of a plurality of horizontal and vertical succession of finished elements. Through through holes in the prefabricated elements protrude masonry piles, which are connected via coupling sleeves with injection bearing piles. The prefabricated elements rest on supports which are screwed onto the lower sections of the wall piles. In order to secure the bearing piles against lateral emigration, attached to the periphery of the coupling sleeve soil nails, which protrude at different angles to the adjacent soil. The prefabricated elements are made of cast concrete profile blocks with their vertical center plane symmetrically arranged through holes for the wall posts. In the horizontal direction, the finished elements are connected by means of a tongue and groove connection. The remaining cavities of the prefabricated elements are poured out after creating the wall with concrete, but this can lead to uneven edges on the top of the wall, which could cause problems in the desired resistance to frost deicing.
Another disadvantage of this retaining wall construction is that it is expensive and therefore rather expensive in the establishment, especially because many individual profiled blocks must be pushed over previously attached support and masonry piles and stacked on top of each other. It is necessary that first the support piles are driven at precisely defined positions in the ground. In addition, due to the relatively weak anchoring of pegs, the support structure can not absorb large transverse loads - among other things, because they attack the coupling sleeves below the wall. So-called earth reinforcements are used to accommodate higher shear loads, but in many cases this is not possible.
From CH 684 102 a retaining wall construction is known, which is also anchored with vertically driven injection piles in the ground. To accommodate the transverse loads, it also has at different angles obliquely driven injection piles. Reinforcing bars are fastened between the ends of the vertical injection piles protruding from the ground. The free ends of the oblique injection piles are connected to the vertical injection piles. The actual retaining wall made of concrete is then created in a known manner by means of a formwork by the ends of the injection piles and the reinforcing bars are poured into concrete. Again, the construction of the support structure on site time-consuming and therefore expensive.
Another known system, like the retaining wall construction of CH 676 015, several profiled blocks made of concrete. In contrast to the retaining wall construction of CH 676 015, the transverse anchors, e.g. Soil nails, however, fixed by means of steel cables to the wall posts, e.g. by flipping. For this purpose, a notch in each profile stone is struck for attaching the steel cables. Also in this case, creating the retaining wall construction is time-consuming and expensive. Due to the centrally arranged passage openings for the wall piles, which are later completely concreted, the finished retaining walls have thicknesses of 25 cm or more, which can also lead to increased material costs, especially for concrete.
PRESENTATION OF THE INVENTION
An object of the invention is, respectively, a retaining wall element. specify a retaining wall, which does not have the aforementioned disadvantages. The retaining wall element is intended in particular to allow a quick and cost-effective creation of a retaining wall.
The object is achieved by a retaining wall element with the features of claim 1. The retaining wall element according to the invention, comprising a wall body with a support side, is accordingly characterized in that at least one projecting connecting element for an anchor rod, preferably drilling anchor, is provided on the support side of the wall body, each having at least one continuous anchor opening for the implementation and attachment of the anchor rod, preferably of the drilling anchor. An important aspect of the invention is that the attachment of the anchorage of the retaining wall element with respect to the wall body is partially displaced outwards.
To create a retaining wall several prefabricated inventive retaining wall elements can be positioned at the desired location, preferably on a foundation along the slope to be secured, so that the support side of the Wandköpers with the cantilevered connection elements to the slope respectively. Embankment or street is directed. The wall body is erected more or less vertically, but if necessary can also be inclined upwards to the slope by a few degrees. To fix the retaining wall elements anchor rods are advantageously performed by the anchor openings of the projecting connection elements and anchored in the ground. The attachment of the anchor rod on the respective retaining wall element is preferably achieved by concreting the anchor rod in the anchor opening.
The inventive retaining wall elements can be used very diverse. You can e.g. for securing buildings, in particular roads, on slopes, for garden walls or for securing the shore of waters, e.g. be used against flood. The retaining wall elements can also be used for the construction of noise barriers.
Depending on the field of application can be used for anchoring the retaining wall known self-drilling anchor or injection anchor, which allow a self-drilling installation with simultaneous use of the anchor rod as a drill rod with a lost drill bit. After drilling the self-drilling anchor into the ground these are respected by injecting an injection medium. Injection mortar anchored in the underground. The anchor rod, which is anchored by the injection agent in the ground, can be fixed in the same step with the same injection agent in the anchor hole, which allows a particularly simple and fast and therefore cost-effective construction of a retaining wall. It is also known per se drill anchors are used, which are drilled cased. In doing so, e.g. already pre-injected anchor rods introduced into the drill pipe, which are then completely surrounded in the ground by the injection mortar. Another advantage of the inventive retaining wall element is the arrangement of the substantially vertical anchor rods, which are outside the wall body. In this way, in the production of the retaining wall elements, the thickness and shape of the wall body easily varies and the connection elements with the anchor openings can be positioned at the desired locations for optimum introduction of force. For example, a wall body with thicknesses of less than 25 cm can be created, resulting in significant material savings compared to the known retaining wall systems, especially those with double-walled retaining wall elements leads. On the other hand, wall bodies with larger thicknesses of e.g. Be made over 25 cm, if very large loads are to be expected.
In order to achieve the highest possible application of force in the connecting elements as short a distance as possible, a Hüllwellrohr made of metal can form the continuous anchor opening. Preferably, the connecting element is made of reinforced concrete and the Hüllwellrohr is inserted and cast in the manufacture of the retaining wall element in the shape of the connecting element.
The wall body will also be made of reinforced concrete or, depending on the needs and application of other materials such. Metal, wood or plastic. Stone baskets can also be used as a wall body. Also, the surface structure, e.g. through washed concrete, and the color of the wall body can be freely chosen. It is also possible to produce wall bodies which easily achieve the desired resistance to freeze-thawing.
For the cantilevered connection elements two types of anchor openings are usually provided. An anchor opening of the first type is in particular designed for a substantially vertical anchor rod. An anchor hole of the second type is formed for an oblique, provided as Querzuganker anchor rod. Both types of anchor openings are preferably continuous from top to bottom of the terminal. The arrangement of the connection elements and the type of anchor openings depend on the expected forces, which should hold the retaining wall.
The retaining wall element may thus have one or more cantilevered connection elements, wherein a cantilevered connection element has an anchor opening of a first type for a substantially vertical anchor rod and / or an anchor opening of a second type for an oblique, provided as Querzuganker anchor rod. However, the orientation of the anchor holes may also vary depending on your needs.
The axis of an anchor opening of the first type is preferably inclined at an inclination angle of 0 to 5 degrees, so that an anchor rod can be driven substantially perpendicular or slightly obliquely forward (visible side of the retaining wall) in the underground. The anchoring of the first type serves on the one hand to support the retaining wall element in the vertical direction and on the other hand prevents a displacement of the lower region of the retaining wall element in the horizontal direction. The axis of an anchor hole of the second type is preferably inclined at an inclination angle of 15 to 30 degrees, preferably about 20 degrees, to the perpendicular (a vertically erected retaining wall), so that an anchor rod can be driven obliquely away from the wall into the ground. The anchoring of the second type mainly prevents displacement of the retaining wall element, in particular the upper area, in the horizontal direction. Further, if necessary, at least one substantially horizontal anchor opening may be provided, which e.g. extends from the visible side through the wall body to the support side and is designed for substantially horizontal Querzuganker. If required, this anchor opening can likewise lead through a projecting connecting element and can also be formed by a Hüllwellrohr. Such anchors introduced from the visible side can also be used as control anchors on which the anchor forces can be measured. Depending on the field of application, the configuration of the retaining wall element according to the invention accordingly also permits anchor openings with other than the indicated angles of inclination.
The wall body is preferably plate-shaped and may have the following dimensions: a height of 0.5 m to 3.5 m, preferably 1 m to 2.5 m; a width of 2m to 8m, preferably to 4m, more preferably about 3m; and a thickness of 10 cm to 40 cm, preferably about 15 cm to 25 cm. If stone baskets are used as a wall body, they can be thicker than 40 cm. The thickness of the wall body can taper from bottom to top. Depending on the place of use resp. Slope of the retaining wall, the upper edge and / or the lower edge may be inclined in the mounted state in the longitudinal direction of the retaining wall. The lateral edges are preferably vertical in the mounted state, so that a plurality of retaining wall elements can be arranged side by side.
The cantilevered connection elements can be arranged as needed in different numbers and at different locations on the support side of the wall body, with cantilevered connection elements with anchor openings of the first type preferably in the lower region of the wall body resp. are arranged at the foot of the wall body. Particularly preferably, they are aligned with the lower edge of the wall body and serve as an adjusting foot for easy installation of the retaining wall elements, in particular when a foundation has been erected before placing the retaining wall element. Projecting connection elements with anchor openings of the second type are preferably arranged in the upper region of the wall body, so that unimpeded attachment of the anchor rod resp. Drilling a drill anchor is possible. However, they are preferably offset from the upper edge of the wall body by a few centimeters, preferably by 10 to 40 cm, so that they would be completely obscured by any road surface or soil or the like, and an anchor rod should not extend over the upper edge of the wall Wall body would protrude.
If a plurality of projecting connecting elements are provided, these are preferably substantially rectangular or trapezoidal blocks and may have the following dimensions: a height of 50 to 100 cm, preferably about 70 cm; a width of 20 cm to 40 cm, preferably 25 cm to 30 cm; and a depth of 40 cm to 70 cm, preferably about 60 cm. The anchor opening preferably has a diameter of 120 mm to 180 mm, preferably 150 mm to 160 mm. Depending on the field of application, the size of the connection elements and the diameter of the anchor openings can be adapted to the expected loads accordingly.
The plurality of cantilevered connection elements are preferably arranged in the longitudinal direction of the wall body at regular intervals from each other, more preferably at a distance of about one meter. In this case, cantilevered connection elements preferably alternate with anchor openings of the first type and of the second type. Also, in each case a cantilevered connection element can be arranged on the two lateral edges of the wall body. The two outer marginal connecting elements can each be offset inwardly by a few centimeters, preferably 2 to 5 cm, relative to the lateral edge of the wall body, so that adjacent retaining wall elements can not be arranged planar with respect to their visible side but at an angle to one another.
An embodiment of the inventive retaining wall element has a height of about one meter and a width of about three meters. In this case, all connecting elements are arranged in alignment with the lower edge of the wall body. Preferably, the retaining wall element has two connection elements with anchor openings of the first type, which are each arranged on one of the lateral edges of the wall body. Preferably, they are offset from the lateral edge of the wall body by a few millimeters or centimeters inwards, so that two adjacently erected retaining wall elements can be arranged at an angle to each other. A connection element with an anchor opening of the second type is arranged in the longitudinal direction, preferably in the middle of the wall body.
A further embodiment of the inventive retaining wall element has a height of about two meters and a width of about three meters. In contrast to the embodiment with a height of about one meter, not all connection elements are arranged at the same height. The connection element with an anchor opening of the second type is arranged in the upper region of the wall body, so that the anchor opening is easily accessible for unhindered attachment of the anchor rod or for insertion of a drilling anchor. However, it is preferably offset from the upper edge of the wall body by a few centimeters, preferably 10 to 40 cm, down so that it would be completely obscured by any road surface or soil or the like, and an anchor rod would not extend over the upper edge of the wall body would protrude.
Wall body and connection elements of the inventive retaining wall element are preferably made in one piece from reinforced concrete. The inventive retaining wall elements can be used on slopes but also in dams.
In order to avoid a displacement of two adjacent retaining wall elements along their contact surfaces during anchoring, the retaining wall element may have lateral connecting means for connecting two adjacent retaining wall elements. For this purpose, on both sides of the lateral edges of the wall body arranged cantilevered connection elements have at their outwardly directed side in a vertical direction continuously extending groove or recess. Between the connecting elements of two adjacent retaining wall elements thus creates a recess which in the assembly of the retaining wall with concrete, e.g. can be filled with stamped concrete or with injection mortar (after previous foaming or sealing of the opening). In this way, a displacement of the retaining wall elements along their contact surfaces during the attachment of the anchor rods can be prevented. Alternatively, the sides of the wall bodies of two adjacent retaining wall elements may have a tongue and groove connection. Also, the cantilevered connecting elements arranged on both sides on the lateral edges of the wall body can each have a bore for bolts, mandrels or the like.
On the top of the wall body connections for railings, barriers, noise barriers, crash barriers and the like may be provided. Furthermore, the retaining wall element can have transport anchors for easy placement of the retaining wall elements, which are preferably embedded on the support side in the upper regions of the wall body.
To create higher retaining walls, the retaining wall elements on the top of the wall body recesses for mandrels, mounting plates or similar connecting means, by means of which another, preferably plate-shaped, Wandköper can be placed. This further wall body preferably has no projecting connection elements and is made by means of anchoring rods driven underground by the wall body into the ground in the conventional manner, e.g. with anchor plate and ball nut, fixed. The additional, preferably plate-shaped, wall body can have a height of up to four meters. On the additional plate-shaped wall bodies further, preferably plate-shaped, wall body can be mounted in the same manner.
The top resp. Crown of the wall body of the retaining wall member may have a convex shape and the underside of the additional plate-shaped wall body may have a concave shape, so that superposed wall body can not be arranged planar with respect to the visible side but at an angle to each other.
In order to build several retaining wall elements to each other, the retaining wall elements in the upper region may have a aligned with the upper edge of the wall body platform on which second retaining wall element can be made. If necessary, the retaining wall elements can be fastened in a conventional manner by means of anchor rods driven through the wall body into the ground from the visible side.
The invention further relates to a retaining wall of a plurality of longitudinally juxtaposed according to the invention retaining wall elements, anchor rods are fastened in each case with one end in the anchor opening. Preferably, the anchor rod is a drill rod of a self-drilling anchor and is secured by means of injection mortar in the anchor opening. The retaining wall can also have a foundation. Further, a septic tank may be provided on the slope side near the foundation. Next, the retaining wall may have additional, preferably plate-shaped, Wandköper, which are placed on the wall body of the retaining wall elements and fastened by means of connecting means. These further wall bodies can be moved by means of anchor rods driven into the ground through the wall body from the visible side in a conventional manner, e.g. with anchor plate and ball nut, to be attached.
The invention further relates to a method for creating a retaining wall according to the invention for securing buildings, in particular traffic routes, on slopes, comprising the following steps: (a) setting up a retaining wall element according to the invention; (b) attaching the anchor rods by driving them through the anchor openings of the cantilevered connection elements into the soil behind; and (c) anchoring the anchor rods in the ground and on the connection elements of the retaining wall element.
Preferably, a drill rods of a self-drilling anchor is used as anchoring rods, which is attached by injection of an injection mortar simultaneously in the soil and in the anchor opening of the respective retaining wall element. If necessary, before the erection of the retaining wall element, a foundation, preferably made of concrete, created. However, it is sufficient to create the foundation only in the area of the connecting elements arranged in alignment with the lower edge of the wall body.
In addition, the invention relates to the use of an inventive retaining wall element for the creation of inventive retaining walls for securing buildings, especially roads, on slopes.

WAYS FOR CARRYING OUT THE INVENTION
Fig. 1 shows a first embodiment of an inventive retaining wall element 1 in a perspective view of the support side 8 with three block-shaped, cantilevered connection elements 3, 4, which are arranged on the support side 8 of a plate-shaped wall body 2. Wall body 2 and connecting elements 3,4 are preferably made in one piece from reinforced concrete. The three cantilevered connection elements 3, 4 are arranged at a uniform distance from each other in the longitudinal direction of the wall body 2 and aligned respectively with the lower edge of the wall body 2. In this way, they form a kind of foot, which facilitates the vertical placement of the retaining wall element. The two outer marginal connection elements 3 are also offset in each case by about 2 to 5 cm from the lateral edge of the wall body 2 inwards and have on the outwardly directed side extending in a vertical direction, continuous groove 7 or recess as a lateral connection means whose Function is described below. In the longitudinal direction of the wall body 2 in the middle between the two lateral connection elements 3, the third connection element 4 is arranged.
The wall body 2 has a height of about one meter and a width of about three meters and is about 10 cm thick. The cantilevered connection elements 3, 4 are substantially rectangular and protrude from the support side 8 of the wall body 2 by approximately 50 to 80 cm, preferably approximately 70 cm. The cantilevered connection elements 3, 4 have a height of about 40 cm to 70 cm, preferably about 60 cm, and are offset from the upper edge of the wall body down so that they are completely covered by any road surface or poured soil or the like and an anchor rod 12 would not protrude beyond the upper edge of the wall body 2.
The projecting connection elements 3, 4 each have an anchor openings 5, 6 for attachment of anchor rods 11,12, as described later in FIGS. 6 and 7. There are two types of anchor openings 5, 6 are provided, wherein a first type 5 for substantially vertical anchor rods 11 and a second type 6 for obliquely provided as Querzuganker anchor rods 12 are formed. The two outer connection elements 3 arranged on the side edges of the wall body 2 each have an anchor opening of the first type 5, which has an angle of inclination of approximately 5 degrees, so that an anchor rod 11 slopes slightly forward, i. towards the visible side 9 of the wall body 2 out, can be driven into the underground. The centrally located connection element 4 has an anchor opening of the second type 6, which has an inclination angle of about 20 degrees, so that an anchor rod 12 obliquely backwards, i. can be driven away from the support side 8 in the underground. The anchor openings 5, 6 are preferably made of metal in the connecting elements 3, 4 sheath corrugated pipes, as they are e.g. used in prestressed concrete structures, molded.
FIG. 2 shows a plan view and FIG. 3 shows a side view of the retaining wall element 1 from FIG. 1. In particular, in Fig. 3, the inclined from the top to the bottom of the connecting elements 3, 4 continuous anchor openings of the first and second type 5, 6 are shown in dashed line. The upper opening 10 of the anchor opening of the second type 6 is arranged in such a spaced from the support side 8 of the wall body 2, that an anchor rod 12 can be driven from above without hindrance through the armature opening 6 in the underground. In Fig. 3 also obliquely provided as Querzuganker anchor rod 12 is shown.
FIG. 4 shows a second embodiment of a retaining wall element 1 according to the invention in a perspective view on the support side 8. In contrast to the first embodiment, the wall body 2 has a greater height of about two meters. In order to absorb larger loads compared to the retaining wall element described above, the thickness is about 18 cm. In this case, the central connection element 4 with the anchor opening of the second type 6 offset relative to the other two connection elements 3 in height, preferably about one meter, arranged. The distance of the upper side of the connecting element 4 to the upper edge of the wall body 2 should be approximately the same as in the first embodiment, so that an anchor rod 12 can be driven from above without hindrance through the armature opening 6 into the ground. FIG. 5 shows a side view of the retaining wall element 1 from FIG. 4, in which the height-offset arrangement of the connecting element 4 with an anchor opening 6 of the second type relative to the two connecting elements 3 with an anchor opening of the first type 5 can be seen. In Fig. 5 also an obliquely provided as Querzuganker anchor rod 12 is shown.
6 and 7 each show a retaining wall 13 of two longitudinally juxtaposed retaining wall elements 1 of the first resp. the second embodiment. Between the adjacent connection elements 3, a recess 15 is provided as a lateral connecting means, which respectively by the two vertical grooves. Recesses 7 is formed in the connection elements 3. When erecting the retaining wall 13, this recess 15 can be filled with concrete, whereby a relative displacement of the two retaining wall elements 1 to each other during the attachment of the anchorage is prevented.
The retaining wall 13 further comprises a plurality of anchor rods 11,12, which are driven from above through the armature opening 5, 6 in the underground. Ground and slope are shown schematically in Fig. 9. To attach the anchor rods 11, 12 to the retaining wall elements 1, these are embedded in the anchor openings 5, 6. Preferably, the drill rods of self-drilling anchors are used as anchor rods 11, 12, which are simultaneously fixed by means of injection mortar in the ground and on the retaining wall element 1. The anchor openings 5, 6 are preferably made of metal in the connecting elements 3, 4 sheath corrugated pipes, as they are e.g. used in prestressed concrete structures, molded.
As shown in Fig. 8, the wall body 2 of the retaining wall member 1 may have a longitudinal direction of the wall body 2 inclined upper edge 14, so that a plurality of retaining wall elements 1 with the upper edge 14 aligned and the lower edge offset in height to each other can be. This is particularly advantageous in securing traffic routes with a slope.
Fig. 9 shows a retaining wall 13 with a plurality of juxtaposed and stacked retaining wall elements 1. The retaining wall elements are similar to the retaining wall elements of the embodiment of Fig. 4, but have a flush with the upper edge of the wall body 2 platform 25. The anchor openings of the connection elements 3 arranged on both sides are arranged farther away from the support side, so that despite the platform 25, an anchor rod 11 can be guided from above through the anchor opening 5. Another retaining wall element 1 is provided with the connection elements 3 arranged on both sides on the platform 25 and can be connected to the lower retaining wall element with connecting means 21, here in the form of bolts. For connecting two laterally adjacent retaining wall elements 1, a connecting means 20 in the form of a bolt can also be used. The upper retaining wall element is additionally fastened with substantially horizontal anchor rods 23.
10 and 11 show a schematic representation of a retaining wall according to Fig. 4 with an attached wall body 22 for supporting a road 16. In Fig. 10 is a plan view and in Fig. 11 is a section along the section line A-A shown. On the support elements 1 additional plate-shaped wall body 22 are placed. For this purpose, the wall body 2, 22 respectively on the top. Bottom recesses for mandrels, mounting plates or similar fasteners on. The additional plate-shaped wall bodies 22 may be up to four meters high and are provided with a plurality of anchor rods 23 driven into the ground by the wall body 22 from the visible side, in a conventional manner, e.g. with anchor plate and ball nut, fixed. The illustrated wall body 22 has a height of about 1.5 meters. The retaining wall 13 is erected on a foundation 19 and anchored by means of the anchor rods 11, 12 in the ground 17.
