Уже известны способы разработки грунтов посредством нагнетани воды П|ри помощи внедр емых в грунт пойнтов. Предлагаемый способ от 1ичаетс , тем, что дл обрушени отделённой пойнтами грунтовой призмы в карьер в грунт внедр ют р д пойнтов на некотором рассто нии от бровки карьера , вдоль неё.Methods of excavation by means of water injection are already known; | | using the points introduced into the soil. The proposed method from 1 is caused by the fact that in order to break a ground point prism separated into points into the quarry, a number of points are introduced at some distance from the edge of the pit, along it.
На чертеже изображена схема расположени пойнтов.The drawing shows the layout of the points.
Способ разработки грунта состоит в том, что в грунт внедр ют р д пойнтов 1 на некотором рассто нии как друг от друга, так и от бровки карьера, вдоль неё.The method of developing the soil consists in introducing into the soil a number of points 1 at a certain distance both from each other and from the edge of the pit, along it.
Напорна вода при давлении не выше трёх атмосфер вводитс в толш,у грунта по пойнтам (а-19 мм), располагаемым на определённых рассто ни х (например 3-6 м) друг от друга и от бровки карьера. Вода по выходе из открытого нижнего конца пойнта, устремл сь по линии наименьшего сопротивлени , т. е. вдоль стенок пойнта вверх к дневной поверхности, поглощаетс близлежашими сло ми грунта, прилегающими к пойнту. По достижении заданной глубины (от 4 до 18м) через 4-8 часов, в зависимости от породы грунта, вдоль линии расположени пойнтов по вл етс продольна трещина с последующим увеличением до предела, при котором грунтова призма, отделённа от грунтового массива этой трещиной , опрокидываетс на подошву карьера. При падении призмы на подошву карьера происходит отбрасывание грунта на рассто ние, равное полуторной высоте карьера, с раздроблением грунта на мелкие куски. Лини обрушени , на которой располагаетс ось опрокидывани грунтовой призмы, проходит ниже глубины заложени пойнтов на 1-5 м.Pressurized water at a pressure of no more than three atmospheres is introduced into the bulk, near the ground at points (a-19 mm), located at certain distances (for example, 3-6 m) from each other and from the edge of the quarry. Water leaving the open lower end of the point, rushing along the line of least resistance, i.e., along the point walls upward to the surface, is absorbed by the adjacent layers of soil adjacent to the point. Upon reaching a predetermined depth (from 4 to 18m) after 4-8 hours, depending on the rock of the soil, a longitudinal crack appears along the line of points, with a subsequent increase to the limit at which the soil prism, separated from the soil mass by this crack, overturns on the sole of a quarry. When a prism falls on the bottom of a quarry, the soil is thrown to a distance equal to one and a half height of the quarry, with the soil breaking up into small pieces. The line of collapse, on which the axis of the overturning of the earth prism is located, passes below the depth of laying the points by 1-5 m.
Предмет изобретени Subject invention
Способ разработки грунта путём нагнетани воды при помощи внедр емых в грунт пойнтов, отличающийс тем, что р д пойнтов внедр ют в грунт на некотором рассто нии от бровки карьера, вдоль неё, с целью обрущени отделённой пойнтами грунтовой призмы в карьер.The method of developing the soil by injecting water with the help of points introduced into the soil, characterized in that a number of points are inserted into the soil at some distance from the edge of the quarry, along it, in order to bring the separated prints of the soil prism into the quarry.
