(54) СПОСОБ СТРОИТЕЛЬСТВА ДРЕН(54) CONSTRUCTION METHOD OF DRAIN
Изобретение относитс к области строительства и касаетс , в частности , мелиоративных систем. Известен способ строительства дре включающий отрыв траншеи, укладку в нее труб и фильтруквдей обсыпки и засыпку траншеи вынутым грунтом 1. Недостатком способа вл етс мала фильтрационна способность дренажной засыпки, в следствие чего про исходит быстрое заиливание дрен. Известен способ улучшени физичес ких свойств т желых почв путем внесе ни оструктуривающего раствора на по верхность почвы 2. Однако этот способ не обеспечивает полноты обработки дренажной засып ки и недостаточно эффективно предохран ет дренажные сети от заиливани . Известен способ строительства дрен, включающий отрыв траншеи, укладку в нее труб с последующей их за сыпкой и обработку дренажной засыпки . Причем дренажную засыпку предварительно обрабатывают ингибтором заи ливани дрен 3. Недостатком этого способа вл етс необходимость частой промывки дре нажной сети в процессе ее эксплуатации и низка фильтрационна спосоСность дренакной засыпки в следствие ее гравитационного уплотнени . Целью изобретени вл етс повышение эффективности работы и увеличение срока службы дренажной сети путем повышени фильтрационной способности и суффозионной устойчивости дренажной засыпки. Поставленна цель достигаетс тем, что непосредственно после засыпки труб осуш.ествл ют обработку дренажной засыпки оструктуривающим раствором путем подачи его под напором через дрену. В качестве оструктуривающего раствора используют известковое молоко. В предлагаемом способе под действием оструктуривающего раствора, подаваемого через дрены, происходит закрепление рыхлой структуры дренажной засыпки по всему ее объёму, улучшение фильтрационной способности и диффузионной устойчивости как дренаж ной засыпки так и окружающего дрену грунта, что снижает вынос твердых частиц грунта в дренажные трубы и предохран ет их от закливани . Пример. Если дренажна сеть на участке состоит из отдельных дрен, усть которых выход т в канал, тоThe invention relates to the field of construction and concerns, in particular, land reclamation systems. There is a known method of building a tree, which includes tearing a trench, laying pipes and filtering it in and filling the trench with excavated soil 1. The method has a low filtration capacity of the drainage layer, resulting in rapid silting of drains. There is a method of improving the physical properties of heavy soils by depositing an structural solution to the surface of soil 2. However, this method does not ensure the completeness of the drainage charge processing and does not effectively prevent the drainage networks from silting. There is a method of construction of drains, including the separation of the trench, the laying of pipes in it, followed by their dumping and processing of drainage backfill. Moreover, the drainage bed is pretreated with a drainage inhibition inhibitor 3. The disadvantage of this method is the need for frequent flushing of the drainage network during its operation and the low filtration capacity of the drainage backfill due to its gravitational compaction. The aim of the invention is to increase the efficiency and increase the service life of the drainage network by increasing the filtration capacity and suffusion stability of the drainage bed. This goal is achieved by the fact that immediately after backfilling of drainage pipes, the drainage backfilling is treated with an structuring solution by feeding it under pressure through a drain. Lime milk is used as an ostructuring solution. In the proposed method, under the action of an structuring solution supplied through drains, the loose structure of the drainage bed is consolidated throughout its volume, the filtration capacity and diffusion stability of both the soil drain and the surrounding drainage are improved, which reduces the removal of solid soil particles into the drainage pipes and protects em them from sticking. Example. If the drainage network on the site consists of separate drains, the mouth of which goes into the channel, then
после завершени дреноукладчиком проход ,а, к устью дрены присоедин ют ишанг от емкости с химмелиорантом, при этом предусматриваетс возможность выхода из дрены воздуха,и начинают закачку под дашлением 2-4 м водного столба оструктуриванвдего раствора . Распростран сь вокруг дрены и поднима сь вследствие давлени вверх 1по щели, мелиорант выходгт на поверхность , что можно наблюдать визуально.after completion of the passage, as well as the drainage, the ysheng from the chemical meliorative tank is provided to the drainage mouth, while air is allowed to escape from the drainage, and pumping of 2–4 m water column of the ostrate structure into the drainage is started. Spreading around the drain and rising due to the pressure upward along the slit, the ameliorant comes to the surface, which can be observed visually.
После этого шланг отсоедин ют от дрены, а ее устье закрывают какимлибо образом дл предотвращени утечки раствора до полного его впитывани почвой.Thereafter, the hose is disconnected from the drain, and its mouth is closed in some way to prevent leakage of the solution until it is completely absorbed by the soil.
В случае дренажной системы, объединенной коллектором, целесообразно закачку химмелиоранта проводить не отдельно на каждой дрене, а в целом в систему; подключа емкость с острук турив ак цим раствором к устью коллектора ..In the case of a drainage system connected by a collector, it is advisable to inject the chemical meliorant not separately at each drain, but as a whole into the system; Connecting the tank with a sparking fluid solution to the mouth of the collector ..
Предложенный способ может быть применен и при строительстве дренажных систем траншейным и уэкотраншейным способами. tThe proposed method can be applied in the construction of drainage systems by trench and electric excavation methods. t
Преимуществе предлагаемого спосо-; Ьа состой в увеличении срока работы дренажа без промывки и в улучшении The advantages of the proposed method; Ba is consistent in increasing the duration of drainage work without flushing and in improving
без дополнительного рыхлени агрофизических свойств засыпки.without additional loosening the agrophysical properties of the backfill.
