Description

Изобретение относитс к строительству автомобильных и железных дорог на слабых грунтовых основани х.The invention relates to the construction of roads and railways on weak unpaved foundations.
Известен способ возведени земл ного полотна на слабом грунтовом основании путем полного или частичного удалени слабого грунта и замены его привозным грунтом 1.There is a known method of erecting a landbed on a weak soil foundation by completely or partially removing weak soil and replacing it with imported soil 1.
Недостатки такого способа состо т в малой несуп1ей способности основани , низкой эффективности и высокой трудоемкости строительства .The disadvantages of this method are the low base capacity, low efficiency and high labor intensity of construction.
Наиболее близким к изобретению техническим решением вл етс способ возведени земл ного полотна на слабом грунтовом основанин , включающий возведение на основании жесткой плиты и последующую отсыпку на нее грунта с уплотнением каждого сло The closest technical solution to the invention is a method of erecting a landbed on a weak soil base, including erecting a hard slab on the basis of a slab and then filling it with soil and compacting each layer.
2.2
Недостатки данного способа заключаютс в неудовлетворительной несущей способности основани и наличии просадок земл ного полотна .The disadvantages of this method are the unsatisfactory carrying capacity of the base and the presence of subsidence of the earth bed.
Цель изобретени - снижение просадочных свойств земл ного полотна и увеличение несущей способности основани .The purpose of the invention is to reduce the subsidence properties of the earth bed and increase the bearing capacity of the base.
Достигаетс это тем, что жесткую плиту возвод т путем укладки на основание сло грави , поверх которого размещают покрытую битумом металлическую сетку, и последующего замоноличивани их цементно-песчаным раствором.This is achieved by the fact that the rigid slab is erected by laying a layer of gravel on the base, on top of which a bitumen-coated metal grid is placed, and then monolithing them with a cement-sand mortar.
Способ осуществл ют следующим образом.The method is carried out as follows.
На подготовленную поверхность слабого грунтового основани укладывают тонкий слой грави и поверх него нат гивают арматурную сетку, предварительно покрытую в зким битумом. Затем сетку и слой грави замоноличивают цементно-песчаным раствором. После схватывани раствора послойно укладывают и уплотн ют грунт земл ного полотна до проектной отметки.A thin layer of gravel is placed on the prepared surface of a weak soil base and a reinforcing mesh previously coated with viscous bitumen is stretched over it. Then the grid and layer of gravel are monolithic with cement-sand mortar. After setting the solution, lay the soil in layers and compact the soil of the earth bed to the design elevation.
Использование описываемого способа дает существенный экономический эффект за счет сокращени высоты насыпи из привозного дорогосто щего грунта и увеличивает срок земл ного полотна путем повышени несущей способности и прочности основани и уменьшени возможности по влени неравномерных деформаций.The use of the described method gives a significant economic effect by reducing the height of the embankment from expensive imported soil and extends the length of the earth bed by increasing the bearing capacity and strength of the base and reducing the possibility of uneven deformations.
