Trapeze type support strut assemblies attach pipes, conduit, and tubes to vertical and horizontal surfaces in a sanitary manner. The strut assemblies repel contaminants, are easy to inspect, and easy to clean. Structures to provide seismic stability to trapeze type support strut assemblies may also be used.

The invention discloses a polymer grout injected earth-rock dam and a construction method thereof. The polymer grout injected earth-rock dam comprises rockfill, polymer grout injected rockfill and a face slab. A dam body is built with the rockfill, with the rockfill and a clay core wall or with the face slab and the rockfill by filling. Overall dam grouting or grouting on the upstream surface and the downstream surface of the dam body are performed during filling. The problems that conventional earth-rock dam allows no passage of water, accelerations at the top of the dam are high, the rockfill mass is easy to loosen and the like are solved, and the polymer grout injected earth-rock dam is simple in structure and convenient in construction, has evidently improved seismic stability, has wide application prospect and is an economical and practical dam.

The invention relates to a chassis of a compact shelf, in particular to a chassis of a compact shelf with an anti-shock locking function. A compact rack chassis with anti-vibration locking function can make adjacent compact racks lock each other, so that the entire row of compact racks form a whole to lock each other and support each other, and can achieve the effect of anti-seismic stability. Such a compact rack chassis with anti-shock locking function includes a base, a bracket, a cover plate, a driving part and a docking part, the driving part drives the entire compact rack to move on the guide rail, and the docking parts are symmetrically arranged on both sides of the base. Adjacent said compact shelves are butted together through adjacent said docking parts. When two adjacent compact racks are close to each other, the entire row of compact racks are butted with each other to form a whole, so that all the dense racks are locked to each other and support each other, which can achieve the effect of anti-seismic stability.

The invention relates to an energy-dissipating anti-sliding pile with two limbs and a construction method thereof. The anti-sliding pile includes a main limb pile body, an auxiliary limb pile body, a sliding pair and an energy-dissipating connecting rod system. The anchorage section of the main pile body is the anchorage section of the anti-sliding pile, and the small section of the upper part of the main pile body forms the load-bearing section of the main pile body; the auxiliary pile body is located on the side close to the mountain, and the bottom of the auxiliary pile body passes through the It is connected with the variable cross-section in the middle of the main pile, so that the auxiliary pile can have a certain horizontal displacement relative to the main pile; the auxiliary pile, the energy-dissipating connecting rod system and the loaded section of the main pile constitute the anti- The loaded section of the slide pile. When an earthquake occurs, a certain relative displacement is allowed between the auxiliary leg pile and the main leg pile, and the energy-dissipating connecting rod can effectively dissipate the input energy of the earthquake and ensure the function of the main leg pile within the allowable displacement range, so as to achieve The purpose of anti-seismic energy consumption and protection of anti-slide piles is to improve the seismic stability of the slope and ensure the normal working performance of anti-slide piles after earthquakes.

The invention discloses a multi-unit 3D printing manufacturing system capable of achieving continuous production. The system comprises a multi-unit 3D printing unit formed by multiple 3D printing machines. Wheels are mounted at the bottom of the multi-unit 3D printing unit, and suspension modules for improving the seismic stability of the multi-unit 3D printing unit are arranged between the wheelsand the multi-unit 3D printing unit. Each 3D printing machine comprises a printing machine shell, an X-axis movement mechanism, a Y-axis movement mechanism, a Z-axis movement mechanism, a material spraying mechanism, printing supplies, a printing platform and a lifting platform, wherein the Z-axis movement mechanism is located in the printing machine shell and fixedly connected with the Y-axis movement mechanism through the lifting platform, the Y-axis movement mechanism is connected with the X-axis movement mechanism, and the X-axis movement mechanism is located above the printing platform and fixedly connected with the material spraying mechanism. The system has the following beneficial effects that printed models can be automatically stripped from the printing platforms without being damaged by the multi-unit 3D printing manufacturing system, and therefore cyclic continuous production is achieved.
