Definitions
- Wooden poles are widely used worldwide, mainly as supports for power and telephone lines. To give them a sufficient lifespan, it is necessary to apply a preservation treatment to them before their implementation.
- This treatment consists in incorporating into the wood cells an insecticide and fungicide product, in order to make the wood inedible for the microscopic fungi responsible for decay, as well as for insects.
- the processes used are very varied, but they can be grouped into two main categories: dry wood treatment processes and sap wood treatment processes.
- a penetration depth generally limited to 2 cm for most round timber
- the present invention relates to a method for preserving wood in sap or more or less dry, which impregnates the wood in the longitudinal direction and in the radiai direction: a longitudinal injection following the circuit of the raw sap for an overall preservation of the piece of wood; and a radial injection following the elaborate sap circuit, reserved for a specific area or for the whole piece of wood, for an additional and more intense impregnation chosen according to the risks of biological alteration which are specific to it.
- the equipment of FIG. 1 comprises: a supply pipe (1) for treatment product under a pressure of a few bars, a pocket or waterproof cover (2) composed of two elements; a waterproof membrane and a flexible and resistant fabric reinforcement.
- a supply pipe (1) for treatment product under a pressure of a few bars a pocket or waterproof cover (2) composed of two elements; a waterproof membrane and a flexible and resistant fabric reinforcement.
- One or more clamps (3) allow the tight pocket to be strongly applied against the debarked base of the trunk (4) and thus ensure the necessary seal and the retention of the device against the wood being treated.
- a layer of elastic bands (5) improves the sealing of the device.
- the device for radial injection further comprises one or more pieces of curved sheet metal (6) in one or more pieces, for retaining the sealed bag while the device is under pressure.
- Said metal sheet can advantageously be replaced by a flexible and resistant strip (Figure 2) wrapped around the area to be treated, over the waterproof cover.
- the safety system must prevent the device from detaching under the pressure of the processing pressure. It comprises a metal frame (12) applied against the circular plate (8), and connected via the tensioners (13) to a set of two upper and lower rings (14 and 15), of a diameter significantly greater than that of the trunk to be treated, and forming a self-locking system with the latter, as illustrated in FIG. 3.
- the two rings are rigid, they must be extended by an arm which allows the traction force exerted on to be properly oriented. the rings for the self-locking system to work.
- a variant of these devices for longitudinal and radial injection makes it possible to easily impregnate with the same advantages, all kinds of round or non-round wood (pilings, railway sleepers, etc.).
- care must be taken to ensure that one end of the piece of wood to be impregnated remains at atmospheric pressure, so that a flow of the antiseptic product can be established through said piece. Suction from this end is not necessary because the pressure difference between the inlet and the outlet of the product is sufficient for impregnation as rapid as desirable, and in depth.
- the collars are replaced by rods connected two by two by two bolts placed on either side of the piece of wood, while the safety system for the radial injection is reinforced by devices of rectangular section.
