The utility model provides a kind of sound-absorbing crystal wood board hidden type hanging assembly, including suspension mechanism, the bottom fixed mounting of suspension mechanism is equipped with fixed disc, the both sides of fixed disc are fixedly installed with suspension frame, during the application of this technical solution, its hidden structure by setting suspension mechanism and clamping mechanism, will be arranged in the sound-absorbing crystal wood board body top with the components such as suspension plate, hexagonal sleeve, side frame, limit card group, fixed plate is fixed in the top four corners of board, clamping operation is completed in top, so that during use, connection component cannot be seen from side and below, avoid component bare damage decorative integrity, while board side edge has no any shelter structure, can be directly attached when splicing, need not reserve installation space, to reach the effect of improving decorative aesthetic degree and eliminating splicing gap, solve the problem of side edge component bare, splicing gap influence sound-absorbing performance in prior art.

This invention provides a universal cross bracing structure and construction method suitable for inclined cable tower construction, including a cross bracing body and construction platforms at both ends of the cross bracing body. The cross bracing body includes a standard section and transition sections installed on both sides of the standard section, with non-standard sections at the outer ends of the transition sections. The non-standard sections are hinged to the hinged sections. Both the ends of the non-standard sections and the ends of the transition sections have butt joints. Limiting components are provided on the butt joints of the non-standard sections, and a limiting structure that cooperates with the limiting components is provided on the construction platform, allowing displacement of the non-standard section butt joints only in the horizontal direction, and no displacement in the vertical direction. This invention can adapt to the construction of inclined cable towers at any angle. The cross bracing can provide various length combinations to suit different tower spacing requirements. It is flexible in operation, has few limitations, and the connections between components are convenient, minimizing high-altitude work. Most components are bolted together, making installation and dismantling convenient and construction efficiency high.

A method for constructing connecting shaft passages during the tunnel lining construction stage includes the following steps: A vertical shaft is formed using rotary drilling and mud slurry wall support, with a depth greater than the tunnel bottom; support steel pipes are hoisted into the shaft, and the bottom of the support steel pipes is sealed with concrete; the gap between the support steel pipes and the shaft is grouted and backfilled; a horizontal connecting passage is constructed, connecting the tunnel to the support steel pipes in the shaft; the lining structure is constructed inside the tunnel, requiring openings at the portal of the horizontal connecting passage; after the lining structure is completed, the openings, the horizontal connecting passage, and the shaft are sealed. This method enables the rapid establishment of connecting shaft passages to increase the working face during the lining construction stage of deep-buried long-distance water conveyance tunnels, and features low cost, short construction period, and high safety.

The utility model discloses a water conservancy project construction fence relates to water conservancy engineering technical field, include: support column subassembly and a plurality of corrugated baffle subassembly, the corrugated baffle subassembly is installed between two support column subassembly, and the bottom between two support column subassembly is installed with yellow board, the rear side of support column subassembly is installed with inclined support subassembly. The utility model discloses a corrugated baffle subassembly is installed from the lower end of the front side of support column subassembly one by one upwards to the top one by one with the corrugated baffle subassembly from the bottom and pushes, improves installation efficiency and reduces aerial work.

This invention provides a bridge-building machine and its operating method, relating to the field of bridge-building machines. The bridge-building machine includes at least two parallel main beams, the ends of which are supported on corresponding traveling devices. Each traveling device includes a traveling beam anchorable to the top surface of the bridge. The traveling device also includes two hanging wheel assemblies, at least two supporting wheel assemblies, and a drive assembly. The drive assembly is mounted on the traveling beam and includes a drive motor and gears, the gears meshing with a rack at the bottom of the main beams. Hydraulic support legs are also provided on both sides of the main beams, capable of supporting the ground. This invention improves the stability and efficiency of the bridge-building machine's movement.
