Description
Изобретение относитс к строительству тоннелей большого сечени любого назначени , расположенных в скальных породах средней и высокой крепости.The invention relates to the construction of large-section tunnels for any purpose, located in rocks of medium and high strength.
Цель изобретени - сокращение трудозатрат .The purpose of the invention is to reduce labor costs.
На фиг. 1-4 показана последовательность сооружени тоннел по предлагаемомуFIG. 1-4 shows the sequence of construction of the tunnel on the proposed
СПОС()бу.SPOS () bu.
Тоннель большого сечени сооружают в такой последовательности.A large section tunnel is constructed in this sequence.
Проход т верхний рус I (фиг. 1) и закрепл ют кровлю 2 выработки анкерами 3, например железобетоины.ми. Устанавливают опалубку 4 и ар.матуру 5, которую опирают на опалубку 4, и равномерно скрепл ют, например с помощью сварки с анкерами 3. Затем бетонируют обделку свода 6. После набора бетоном обделки свода 6 заданной прочности, например 70°/о от проектной марки на сжатие, снимают опалубку 4. После утого обуривают породу нижнего руса 7, взрывают и вывоз т из тоннел . При этом разработку породы нижнего руса 7 производ т на всю щирину выработки, без оставThe upper Rus I (Fig. 1) passes and the roof 2 of the anchoring 3 is secured by anchors 3, for example, reinforced concrete. Formwork 4 and armature 5, which is supported on formwork 4, are installed and evenly fastened, for example by welding with anchors 3. Then the lining of the vault 6 is concreted. After the concrete is set, the lining of the vault 6 of a given strength, for example 70 ° / o from the design stamps for compression, remove the formwork 4. After this, the rock of the lower Rus 7 is smoked, blown up and removed from the tunnel. At the same time, the development of the rock of the lower Rus 7 is made for the whole width of the mine, without
лени под п тами 8 свода 6 опорных породных полок. Затем бетонируют стены 9 и лоток 10.Sheds at the points 8 of the arch of the 6 support rock shelves. Then the walls 9 and the tray 10 are concreted.
В период сооружени тоннел предлагае- мым способом обделка свода 6 оказываетс надежно скрепленной с помощью анкеров 3 с породным сводом, образуемым в толп1е породы системой анкеров 3 и самой породой под действием силы т жести. Образуетс надежна пространственна конструкци , ограниченна снизу жесткой железобетонной желобчатой (в продольном направлении ) конструкцией обделки свода 6. исключающей возможность образовани вывалов из кровли 2 выработки 1 и «посадкиDuring the construction of the tunnel by the proposed method, the lining of the roof 6 is securely fastened with the help of anchors 3 to the rock arch, formed in the rock mass by the anchors system 3 and the rock itself under the action of gravity. A reliable spatial structure is formed, bounded below by a rigid reinforced concrete grooved (in the longitudinal direction) construction of the lining of the roof 6. It excludes the possibility of the formation of dumps from the roof 2 of generation 1 and "landing
обделки свода 2. Поэто.му при проходке нижнего руса 7 на полное сечение без оставлени под п тами 8 свода опорных породных полок выработка надежно защищена конструкцией верхнего руса.the lining of the roof 2. Therefore, when the lower tier 7 penetrates the full cross section without leaving under the feet 8 of the vault of the support rock shelves, the excavation is reliably protected by the upper trench design.
Таким образом, предлагаемый способThus, the proposed method
позвол ет сократить затраты на сооружение тоннел больщог о сечени , обеспечива высокую технику безопасности 1ри производстве работ.allows you to reduce the cost of constructing a tunnel with a large cross-section, providing a high level of safety during the work.
