A test device has been invented for determining three-dimensional consolidation properties of soils, using a flexible ring permitting displacements and dissipation of the excess pore pressures in both horizontal and vertical directions, and affording determination of coefficients of consolidation in the horizontal and vertical directions, and the modulus of elasticity. The flexible ring consists of a filter fabric around the soil specimen, a rubber membrane around the filter, circular shaped segmented metal plates around the membrane and rubber bands or rings around the plates. Both the incremental loading or triaxial type loading systems can be used with this device. A calibration device for calibration of the flexible ring is used to determine the modulus of elasticity of elastic elements, required for calculating lateral resistance provided by the flexible ring during the test.

The invention discloses a meter gage stabilizing device of railway maintenance machinery. The meter gage stabilizing device comprises a front stabilizing device, a rear stabilizing device and a universal transmission shaft, wherein each of the front stabilizing device and the rear stabilizing device comprises a box body, a clamp oil cylinder, a lever plate, a connection rod, a clamp wheel part, roller shaft parts, a shock excitation part, a horizontal oil cylinder and a fixed pin, wherein shafts of the roller shaft parts respectively penetrate through corresponding sleeper beams on the box body and are connected mutually by the horizontal oil cylinder; a connection line CF of a hinged point C and a hinged point F of the horizontal oil cylinder is parallel to the axes of the shafts of the roller shaft parts; a hinged point C and a hinged D of the clamp oil cylinder are distributed on a vertical position in a staggered manner; in a triangle EFG composed of the hinged points, a vertical line of an edge EG is drawn on a point F to be crossed with the edge EG on a point K; the value of GK / EK is 1-1.6; an angle value of an included angle EFG between an edge EF and an edge FG is 110+ / -10 degrees. According to the meter gage stabilizing device, the power stable work of a meter gage line can be realized, the stress is uniform and reasonable and the reliability is high.

The invention relates to a novel sleeper system in the field of railway tracks. The sleeper system comprises a longitudinal beam type sleeper and an elastic vibration attenuation rail system. The longitudinal beam type sleeper is formed by cascading longitudinal beam type sleeper units. Longitudinal beams of the longitudinal beam type sleeper are transversely and fixedly connected together through connecting pieces; the ends of the opposite longitudinal beams of the adjacent longitudinal beam type sleeper units are connected through sleeper connecting pieces. The elastic vibration attenuation rail system comprises a support; the longitudinal beam type sleeper is arranged on the support; a vibration attenuation facility is arranged between the bottom of the longitudinal beam type sleeper and the support; according to the longitudinal type sleeper, the bending rigidity of the rail is increased, and rail deformation caused by repeated loads is reduced; due to the fact that the longitudinal beams increase transverse resistance and irregularity of a perpendicular rail is reduced, the maintenance workloads are reduced. Due to the fact that connection of the continuous longitudinal beams is kept in the longitudinal direction, the phenomena that the rail settling volume of the ends of the longitudinal beams is too large, and consequently the longitudinal beams are prone to being damaged are avoided. Rail pads are continuously arranged, and therefore foundation vibration, rolling noise and rail wavy deformation are reduced.

The invention relates to the technical field of exploitation of southern ion type rare earth ores, in particular to a southern ion type rare earth ore Luoyang shovel. The invention aims to solve the problem that defects exist in application of a Luoyang shovel in southern ion type rare earth ores. According to the technical points, the southern ion type rare earth ore Luoyang shovel comprises a shovel rod, a shovel barrel, a plurality of shovel barrel tongue-shaped front edges, shovel barrel toothed chutes and an annular oblique ring beam, wherein the shovel barrel comprises a shovel barrel body, and is of a cylinder structure of which the opening direction of the barrel body faces away from the shovel rod; the shovel barrel tongue-shaped front edges are arranged along the shovel barrel body and correspond to the edge of the opening of the barrel body, and each shovel barrel tongue-shaped front edge is provided with a tongue-shaped protrusion of which the tip faces away from the shovelrod; the shovel barrel toothed chutes surround the peripheral wall of the shovel barrel body, and toothed openings face one sides of the shovel barrel tongue-shaped front edges; and the annular oblique ring beam surrounds the peripheral wall of the shovel barrel body, is located at the position where the shovel barrel body is connected with the shovel barrel toothed chutes, and is located on theside facing the toothed openings. The southern ion type rare earth ore Luoyang shovel is simple in integral structure, convenient to operate and high in construction efficiency, is suitable for exploration and exploitation of southern ion type rare earth ores, and is worthy of being popularized and used.
