FR2692610A1 - Precast unit for supporting slopes and retaining walls - is rounded on plan with rugby ball shaped legs front face shaped for placing geotextile membrane using friction for holding - Google Patents

Abstract

The precast unit for supporting slopes and retaining walls is rounded in shape on plan with legs shaped like rugby balls. It can support vertical loads through its legs at angles between 90 and 45 degrees. It supports embankment slopes not exceeding three horizontal to two vertical. The front face (1) is rounded, hollow on its two sides (2) for placing geotextile membrane using friction between the membrane and embankment. The rear face has rounded ends and is flat in the middle. Walls both at 45 degrees and vertical may be built with the same standard unit. USE/ADVANTAGES - Simple design, easy to erect, adapts to vertical and angled loads.

Description

DESCRIPTION
The present invention relates to a device for supporting slopes up to a height defined by the technical process studying the thrusts and resistances, the slope and the content of the ground varying the maximum height of the wall, and makes it possible to decorate the wall by plants of all species that can take root through the bottom or bottom of the element, thus ensuring better soil resistance.

This is to allow creating a plant environment in perfect security. The present invention can also make it possible to produce vertical retaining walls of great height, without modification of the basic elements.

 Until now, the known methods do not make it possible to solve the problem of retaining walls from the small to the large wall, and even vertical with the same prefabricated basic element. The need is always felt to find a light element, inexpensive and easy to implement even at a great height and easily vegetable.

The device according to the invention overcomes these drawbacks. The first characteristic of this stone
ATALUS is the possibility of easily mounting retaining walls or amenities by being able to vary at will the shape of the wall as well as its slope.

- According to embodiments and design
- The elements are placed on top of each other allowing the degree of angle of the structure to be varied.

 The elements, by their design, allow to realize vertical walls and walls at right angles.

 - The design material will preferably be concrete ensuring solidity in the structure, but design by other materials cannot be excluded.

 The accompanying drawings represent the invention in its conventional form without the addition of color, size or vegetation.

 - The bottom of the element can be full or perforated to allow better vegetation.

- Figure 1 shows an example element seen in perspective without notion of scale.

- Figure 2 shows an example of three elements in section as an example of vertical mounting.

- Figure 3 shows an element seen from above.

- Figure 4 shows a top view of an example of three elements placed vertically and possible straight alignment.

- Figure 5 shows a front section showing that the descent of the load due to the support and the weight of the elements is vertical.

 With reference to these drawings, the invention comprises, per element, a front face (1) of rounded shape on the top in front view and in top view, higher than the other three sides of the element, two lateral sides ( 2) solid in the shape of a rugby ball viewed from above and comprising on their upper part a recess (3) allowing the installation of an axis perpendicular to the sides, this axis allows the grip of a geotextile sheet, a rear part ( 4) rounded comprising a flat (5) on its outer face allowing the alignment of the elements for a rectilinear pose, this part can be hollowed out to allow better revegetation of the element, an empty bottom (6), a projection ( 7) at the rear of the front face (1) allows during a vertical installation with the embankments shown in small bubble in the figure (2) not to exceed a slope of 3 for two inside the elements a descent vertical load (8) by superposition.

 This system will make it possible to build conventional gravity retaining walls, or to face massive geotextile reinforcements. The assembly making, in top view a rounded and hollow shape, see figure (3), wider than deep. The different sides being connected by rounded connections (9) in Figure (1). A draft allow the exit of the elements of the mold exists on all the circumference of the elements as well inside as outside of this one. The loads due to the wall and to the support are transmitted by the wings (8) in FIG. 5, the flat surfaces (10) of the wings allowing the good transmission of these loads and by friction the connection of the elements.

Claims (1)

 It is a modular prefabricated element allowing by its rounded shape in top view and by its wings in the shape of a rugby ball a vertical descent of load through its wings a pose which can go from 90 "to 45, all with an embankment whose slope does not exceed three horizontally for two vertically.  This element allows in front view a rounded appearance on the top.  The element has a recess on its two sides allowing the installation of a geotextile sheet, surrounding an axis returning to the recess, the inking of this sheet being produced by friction of the backfill.  The element by design and by its shape allows walls to be made both at 45 "and as many vertical walls, with the same standard element.
