摘要： A method of treating tunnel collapse includes leveling a collapse body and moving a pavilion support under the collapse cavity, lifting a shield plate until a lower edge of the shield plate surpasses a contour line of an initial supporting arch of a tunnel, connecting a bottom column and inserting a padding plate under a column. If the hydraulic prop retracts, the column, the bottom column, the padding plate and the hydraulic prop bear a load from the shield plate. Mounting and connecting the initial supporting arch, welding the intersection point of the column and the initial supporting arch, cutting off the column in the initial supporting arch. Transferring the load of the shield plate from the pavilion support to an initial supporting shed, spraying fast-setting concrete to a grid arch to form a closed shell, and pumping filling material to fill the space of the collapse cavity.

摘要： An apparatus which is positionable between a structure to be lifted and an underlying support surface for lifting the structure utilizes a bottom plate and a cap between which a spacer member, such as a piece of tubing, is positionable and a threaded rod which is threadably received by an internally-threaded opening in the cap. By rotating the threaded rod within the cap, the threaded rod moves lengthwise relative to the cap. Therefore, by positioning the apparatus between a structure to be lifted and an underlying support surface and then rotating the threaded rod within the cap, the bottom plate and the threaded rod act between the structure to be lifted and the underlying support surface to lift the structure.

摘要： The invention relates to a method for joining the functional parts of hydraulic or pneumatic operating devices, such as hydraulic props and rams for underground mining, with a first part exhibiting an external wall section and a second part exhibiting an internal wall section, which are joined together with mutually overlapping wall sections and in this region are connected together, as well as the joining connection for corresponding functional parts. In accordance with the invention both wall sections comprise a depression, which in the connected state form a cavity that is filled with a fluid casting compound of plastic, which after its hardening or solidification connects the two parts together by means of a positive form fit. Since the depressions in the fuNctional parts, preferably made of metal, are filled by the casting compound solidified to a secure locking body, this locking body, which penetrates into the cavities to provide a positive form fit, prevents relative displacements between the two functional parts. At the same time the casting compound hardened in the cavity provides the sealing of the separating gap clearance between the wall sections of the two functional parts.
摘要翻译：本发明涉及一种用于连接液压或气动操作装置的功能部件的方法，例如用于地下采矿的液压支柱和柱塞，具有外壁部分的第一部分和呈现内壁部分的第二部分连接连同相互重叠的壁部分，并且在该区域中连接在一起，以及用于相应的功能部件的连接连接。根据本发明，两个壁部分都包括一个凹陷部分，它在连接状态下形成一个填充有塑料的流体浇注料的空腔，该塑料在其硬化或固化之后，通过正形式将两个部分连接在一起。由于优选由金属制成的功能部件中的凹陷被固化到固定的锁定体上的铸塑组合物填充，所以该锁定体穿透到空腔中以提供正的形状配合，防止两个功能部件之间的相对位移。同时在腔中硬化的铸造复合体提供两个功能部件的壁部之间的分离间隙的密封。
