FR2544687A1 - System of anchorage by cancellation of hydrostatic underpressure - Google Patents

Abstract

The invention, which relates to the field of anchors for boats, consists in creating anchorage surfaces on seals containing liquids for immersion or keeping afloat of floating bodies. This anchorage consists in eliminating all effects of underpressure of the liquid on the resistant element 1, under the combined effects of the cord 2, of the seal 4, of the drain 5. Among the major applications, mention can be made of mooring of boats in lakes and lagoons and keeping floating bodies (wood, for example) immersed.

Description

 The present invention relates to an anchoring device for floating objects or immersed in liquids of all kinds retained in works of the type Reservoirs, artificial lakes, basins, etc., the bottom and walls of which must ensure watertightness, according to the known techniques admitting little or not at all the holes or the tensile forces of the anchorages or the two conjugates.

general, in these works, the anchoring is ensured by devices requiring the mobilization of mechanically resistant elements such as anchor rods, masonry weights, etc., the implementation of which is disproportionate to the desired goal
The device according to the invention uses the effects of hydrostatic pressure to create surfaces or ineme volumes capable of withstanding traction, by suppressing the under pressure of the liquid.

 These so-called nELEMEN-TS RESISTANTSt surfaces or volumes consist of rigid masses designed in various materials according to their own rules of implementation and the resistance elements of the materials relating to them for the transmission of forces, without significant deformation.

 The process consists in adding, to these resistant elements, to benefit from the hydrostatic pressure effect, a sealed system, preventing the circulation of liquid in their underside, possibly combined with a network of perforated drains with gravity operation. - re placed in safety.

 According to a variant, depending on whether it is to equip the installations to be created, the device can be placed directly under the waterproofing which may, if necessary, be interrupted if "the RESISTANT ELEMENT is itself capable" e to perform this function.

 Figure 1 shows, in section, a device according to the invention.

 Figure 2 shows, in section, a variant of this device.

The device shown in FIG. 1 comprises an "ELEMENT REVIS-
TANT "(1) whose shapes, characteristics, dimensions are a function of the forces to bear.

 A connecting bead (2) partial or total, to remain in a state of permanent compression, realizes the junction between (1) and the waterproof support (3).

 An additional anti-pressure film (4) prevents the penetration of the liquid on the underside of the "RESISTANT ELEMENT".

 The perforated drain (5), with gravity operation, is placed in safety.

 A mechanical connection system (6) allows mooring on the anchor.

 In the context of making a new structure, according to FIG. 2, the sealed surface (4), equipped with a special device (3) for the penetration of the anchor (28 into the liquid, passes over the resistant element (1) placed in the ground with the drain (5), thus avoiding the under-pressures of possible groundwater.

 The device according to the invention can be used in all types of tanks or basins made with sealing systems, (whatever the technique used), for the creation of anchors intended to keep equipment flotation or immersion any.

 In particular, it will be interesting to use it for the conservation of wood by immersion in water reservoirs sealed by light film, without resistant support.

 Similar to the so-called nMAsINS "anchors, it can be used for mooring boats and floating bodies in artificial lakes or lagoons.
