SU918192A1 - Round timber storage method - Google Patents

Description

The invention relates to the storage of roundwood in the open air using structures that facilitate cooling and other conditioning of the contents in the stack, and can be used in forestry, woodworking and forestry.

A known method of storing round timber is that the timber is stacked, the base of which is frozen 1.

The disadvantage of this method lies in the considerable complexity of the formation and disassembly of the stack.

The aim of the invention is to reduce the laboriousness of forming and disassembling the stack.

This is achieved by the fact that horizontal piles are laid in the ground for freezing under the base. Channels and let them through the cold air.

FIG. 1 is a diagram of an installation for freezing the base; FIG. 2 shows section A-A in FIG. .

On the pre-prepared pad are placed round.

materials stacked with side shields 2 for shading. The top layer of timber is sprayed with insecticide.

Heat removal from base 3 in order to freeze it during the autumn-winter period is carried out with outside air no higher than –5 s. For this purpose, under the piling area

10 at a depth of 1.0–1.5 m with a pitch of not more than 3 m there is a system of horizontal channels 4 of pipes, connected to the suction pipe 5 and the ventilation unit 6.

Constant air injection (suction) through the system of horizontal channels ensures the freezing of soil around the pipe (channel) by 1.0–1.5 m to form a monolithic base under the stack.

Claims (1)

30 Such a monolithic base in the summer-summer period provides heat removal from the stack and a constant temperature in the stack not higher than + 6-1 ° С / cht is enough to protect the timber from biological damage. (The operation of the ventilation unit is interlocked in such a way that its inclusion at a temperature higher is not possible in order to prevent thawing from the bottom of the pile base. Using the proposed method of storing round timber in outdoor piles reduces the laboriousness of freezing the base to maintain low temperatures. stack to preserve timber from biological damage, equip permanent platforms, eliminate snowing and snow-ice cover timber .. Claim method of storing round timber, which consists in placing the timber in a stack, the base of which is frozen, characterized in that, in order to reduce the labor intensity of forming and disassembling the stack, to freeze the stack under the base, horizontal channels are laid in the ground and passed along cold air in them Sources of information taken into account during the examination 1.
