Abstract
Изобретение вл етс дополнительным к авторскому свидетельству № 901214 и относитс к лесосплаву. Целью изобретени вл етс повышение эффективности определени пригодности дл лесосплава фаутных бревен длиной от 6 до 8,5 м и диаметром гнили в верхнем торце 1/2-3/4 диаметра бревна . Способ заключаетс в том, что измер ют диаметр бревна d и гнили dp на другом торце бревна. Установлено, что при 1/2-2/3 лесосплав бревен возможен в течение t 6 .120 сут., а при . 2/3-3/4 t 6 100 сут. 1 табл. с The invention is additional to copyright certificate No. 901214 and relates to timber timber. The aim of the invention is to increase the efficiency of determining suitability for timber rafting of face logs with a length from 6 to 8.5 m and a rot diameter in the upper end 1 / 2-3 / 4 of the log diameter. The method consists in measuring the diameter of the log d and the rot dp on the other end of the log. It was established that at 1 / 2-2 / 3 timber rafting of logs is possible for t 6. 120 days, and at. 2 / 3-3 / 4 t 6 100 days. 1 tab. with

Изобретение относитс к лесосплаву , а именно к выбору древесины с целью; уменьшени или ликвидации.утопа при: лесосплаве, может быть использо- ван|о на береговых лесных складах, на- прийер, при рассортировке бревен с дровой гнилью на пригодные и непригодные дл лесосплава и вл етс усовершенствованием способа по основно- му авт. св. № 901214.The invention relates to timber rafting, namely the choice of wood for the purpose; reduction or elimination of a trap at: timber rafting, can be used in coastal timber depots, for example, when sorting logs with wood rot into suitable and unsuitable for rafting, and is an improvement of the method according to the main author. St. No. 901214.
Щель изобретени - повышение эффек тидности определени пригодности дл лес;осплава фаутных бревен длиной 6- 8,3 м и диаметром гнили в верхнемThe slit of the invention is an increase in the efficiency of determining the suitability for forest; the melting of face logs with a length of 6–8.3 m and a rot diameter in the upper
тор|це, составл ющем 1/2-3/4 диаметра бр€|вна.The torus is 1 / 2-3 / 4 of the diameter of a br.
,Способ заключаетс в том, что после ;раскр жевки хлыстов на эстакаде из1 ер ют Диаметр гнили (или дупла) и диаметр бревна на верхнем торце. Бревна с диаметром гнили меньше 0,5 ди4метра бревна укладьтают в общий штабель и с началом навигации сбра- сыйают в воду. При диаметре гнили d, составл ющем 0,5-0,75 диаметра бревна idg, и длине бревен 6-8,5 м измер ют диаметр гнили и бревна с другого торца.The method consists in that after; cutting the logs on the overpass erase the diameter of the rot (or hollow) and the diameter of the log at the upper end. Logs with a rot diameter of less than 0.5 cm are stored in a common pile and dropped into water with the start of navigation. With a rot diameter d of 0.5-0.75 log diameter idg and a log length of 6-8.5 m, the rot diameter and the log from the other end are measured.
По результатам измерений .определ - ют пригодность фаутных бревен к длительности лесосплава, а именно: при отношении dp/dg. 1/2-2/3 лесосплав возможен в течение времени t6l20cyT. р при dj. /dj 2/3-3/4 t 100 сут. According to the measurement results, the suitability of the front logs to the length of the timber alloy is determined, namely: with the dp / dg ratio. 1 / 2-2 / 3 timber rafting is possible during the time t6l20cyT. p with dj. / dj 2 / 3-3 / 4 t 100 days.
Пример . Отобрали фаутные бревна длиной 6;6,5 и 8 м с диаметром гнили на одном торце более 1/2 диаметра бревна и диаметромAn example. Fate logs with a length of 6; 6.5 and 8 m were selected with a rot diameter at one end more than 1/2 of the log diameter and
гнили на другом торце не более 1/2 диаметра. После измерени диаметра гнили на противоположном торце проводили рассортировку бревен на две группы: с диаметром гнили на первом торце, составл ющим 1/2-3/4 диаметра бревна, и более 3/4 диаметра бревнаrot on the other end no more than 1/2 of the diameter. After measuring the diameter of the rot at the opposite end, the logs were sorted into two groups: with the rot diameter at the first end of 1 / 2-3 / 4 of the log diameter, and more than 3/4 of the log diameter
Дл определени плавучести опытные бревна заготавливались в зимний период и с наступлением навигации, т.е. сразу после ледохода, были сброшены на воду и в течение всего периода наблщдений находились на плаву в однор дной щети. Результаты опытной проверки способа определени пригодности дл лесосплава фаутных бревен представлены в таблице.To determine the buoyancy, the test logs were harvested in winter and with the onset of navigation, i.e. immediately after the ice drift, they were dropped on the water and were afloat in the single-brush during the entire period of the observations. The results of an experimental test of the method for determining the suitability of the timber logs for timber rafting are presented in the table.
Формул.а изобретени Formula of invention
Способ определени пригодности бревен дл лесосплава по авт. св. № 901214, отличающийс тем, что, с целью повышени эффективности определени пригодности дл ле сосплапа фаутных бревен длиной 6- 8,5 м и диаметром гнили в верхнем торце, составл ющем 1/2-3/4 диаметра бревна, измер ют диаметр гнили и бревна на противоположном торце, причем при диаметре гнили на противоположном торце 1/2-2/3 диаметра бревна лесосплав бревен возможен продолжительностью до 120 сут, а при диаметре гнили 2/3-3/4 диаметра бревна - до 100 сут.Method for determining the suitability of logs for timber rafting according to ed. St. No. 901214, characterized in that, in order to increase the efficiency of determining suitability for timber logs with a length of 6 to 8.5 meters and a rot diameter in the upper end of 1 / 2-3 / 4 of the log diameter, the rot diameter is measured and logs at the opposite end, and with a rot diameter at the opposite end 1 / 2-2 / 3 of the log diameter, timber rafting of the logs is possible for up to 120 days, and with a rot diameter of 2 / 3-3 / 4 of the log diameter - up to 100 days.
