    Abstract: The present disclosure provides a structural engineering dominated geotechnical structured permanent supporting system and a design method, and belongs to the technical field of underground structures. Through the technical solutions, the structural engineering dominated geotechnical structured permanent supporting system comprises a supporting structure designed on the basis of the partial coefficient of a permanent load, the supporting structure is connected to frame columns of a main structure through a plurality of connecting members arranged at intervals, and a partition wall for blocking soil mass is arranged between every two adjacent frame columns to form a permanent supporting system only bearing soil pressure in the horizontal direction of the supporting structure. When the system is designed, the combined action generated after the main structure and the supporting structure are connected is considered, so that the use of materials is reduced, and the cost is reduced.

    Abstract: A rock head for use with an auger borer to bore a passageway through a body of soil and rock and simultaneously laying a pipe in that bored passageway. The rock head has a base connectable to the leading end of the auger. A plurality of movable mounts are provided on the base and a roller cone is secured to each movable mount. A spring is disposed between the movable mount and the base. The spring is compressed as the movable mount pivots the roller cones inwardly toward a central region of the base. This reduces the diameter of the rock head so that it can travel through the bore. Each movable mount is provided with at least one wheel so that it can ride smoothly through the bore. When the rock head exits the pipe, the springs automatically pivots each roller cone outwardly so that at least a portion thereof is disposed beyond the outermost edge of the base. In this second position, the rock head has a greater diameter than the pipe bore and therefore it cannot travel therethrough. When the auger is withdrawn through the pipe, the movable mounts pivot the roller cones from the second position back to the first position, thereby causing the rock head to collapse to a diameter sufficiently small enough to travel back through the pipe.

    Abstract translation: 一个用于与螺旋钻凿孔的岩石头，通过一个通过一块土壤和岩石的通道，同时在这个无聊的通道中铺设管道。 岩石头具有可连接到螺旋钻的前端的基座。 多个可移动的安装件设置在基座上，并且一个滚子锥固定到每个可移动的支架上。 弹簧设置在可移动的底座和基座之间。 弹簧被压缩，因为可移动的安装件使辊子向内转动朝向底座的中心区域。 这样可以减小岩石头的直径，使其能穿过孔。 每个可移动的安装件设置有至少一个车轮，使得其可以顺利地穿过该孔。 当岩石头离开管道时，弹簧自动地将每个滚子锥体向外枢转，使得其至少一部分设置在基座的最外边缘之外。 在该第二位置，岩石头具有比管孔更大的直径，因此它不能穿过其中。 当螺旋钻通过管子撤回时，可移动的安装件将辊锥从第二位置枢转回到第一位置，从而使岩石头塌陷到足够小的直径以便穿过管道返回。

    Abstract: In a method of constructing a reinforced concrete work such as a road tunnel, an underground gallery or a tunnel for an underground railway, there is first excavated an open trench 62 in which there are then placed, consecutively and contiguously, prefabricated hollow concrete frame element 4, the external faces of which have reinforcements 5. A filler concrete 18 is then poured so as to cover the joints between elements and to cooperate with the reinforced concrete of the frame elements and with the reinforcements so as to construct, by consecutive stages and rapidly, a monolithic work. The strength of this monolithic work is appreciably greater than the respective strengths of the prefabricated elements initially placed and of the filler concrete. Finally the trench is filled. Preferably the external reinforcements 5 of the frame elements are such as to cooperate with the filler concrete which is subsequently placed round the elements.

    Abstract: The invention relates to an installation (10) for making a continuous wall in ground (S), the installation comprising: an excavation machine (14) having a frame (16) with a bottom end (16b); determination means (80) for periodically determining the offset between the frame and a first screen while making a second screen in the ground juxtaposed with the first screen; and correction means (50) for periodically correcting the position of the frame (16) so as to reduce the offset as determined by the determination means between the frame (16) and the first screen (E1), and maintain overlap between the longitudinal side of the frame and the longitudinal side of the first screen in such a manner that the second screen is secant with the first screen (E1) over the entire length of the shorter of the first and second screens, thereby forming the wall that is continuous.
