BASE OF EARTH STRUCTURE Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: this primarily relates to construction of temporary roads on loose ground, bogs and marshes with developed root systems of vegetation and stumps, and also to construction of collecting pools so as to prevent penetration into ground water of water-bearing horizons of drilling waste such as poisonous solutions and petroleum products recovered from wells at destruction of pipelines. Base of earth structure has lower course of dry branches of wood spread in layer. Components of dry wood branch course are overlapping each other and protrude to surface of loose ground or bog at sharp angle with respect to axis of road. Base can be provided with additional course of dry wood branch layer which is placed on main lower course. Components of additional course are spread at sharp angle with respect to axis of road and are turned with butt ends of branches towards tops of wood branches of main course. At building of earth structure or site for drilling and operation of well and for ensuring protection against penetration of drilling waste such as poisonous solutions and petroleum products recovered from wells in case of emergencies or destruction of pipelines into ground water of water-bearing horizons, arranged in base is isolating layer made of clay that is kind of barrier of small thickness and also water collecting pool with its wall also made of clay without penetrating into peaty or loose ground. At large width of base foot also possible is to lay pipelines along road being built or drilling site for collection of gas and petroleum products as well as water conduits. Aforesaid earth structure possesses high load-bearing capacity and stability. EFFECT: higher efficiency. 6 cl, 4 dwg
