The invention discloses an anti-seismic energy-dissipation support for an urban comprehensive pipe gallery, and belongs to the technical field of anti-seismic structures and devices of underground comprehensive pipe galleries. The anti-seismic energy-dissipation support is characterized by comprising a main support body, wherein the upper portion of the main support body is provided with a bearingface part used for bearing a pipeline body, the main support body is provided with rigid traction pieces used for fixing the main support body, flexible traction pieces are fixedly embedded in the main support body, the upper ends of the flexible traction pieces are used for being connected with the pipeline body and are arranged at the bearing face part, each flexible traction piece comprises asleeve body fixedly embedded in the main support body and an extension spring arranged in the sleeve body, and the upper ends of the extension springs are connected with the pipeline body. By means ofthe anti-seismic energy-dissipation support, the influence of earthquakes on the pipeline body can be alleviated, and the seismic capacity of the pipeline in the underground comprehensive pipe gallery is improved.

Novel anti-seismic energy dissipation support for urban comprehensive pipe gallery

The invention discloses a laying device of a linear temperature-sensitive fire detector. The laying device comprises a fixing component, a clamping component arranged on the fixing component, and a fastener fixed at the end portion of the fixing component, wherein a clamping cavity for fixing the linear temperature-sensitive fire detector is formed in the clamping component. The problem that in the prior art, a fire detector is damaged due to improper laying is effectively solved, only the fixing component needs to be clamped in a groove in the inner side of C-shaped steel of a cable support during installation, the construction difficulty is small, operation is convenient, and the position of the fire detector is easy to adjust.

The utility model relates to a special telescopic cable anti -seismic support of utility tunnel, banding H shape extensible member in banding U -shaped mounting and U -shaped mounting U -shaped sliding tray, H shape extensible member the transversal H that personally submits appear, is equipped with the locating hole that the position corresponds on its horizontal plate and the U -shaped mountingbottom plate, U -shaped mounting and H shape extensible member top end goes up that equal interval is equipped with that the position corresponds is used for placing the spacing groove of cable. Thisstructure can make the laminating of the bigger degree of utility tunnel design can implement the project in the recent period, reserves distant view development space to the system has considered theeach side influence that the seismic wave comes to cable tape, provides effective protection for power cable, improves the city and combats a natural disaster the ability of prevening disaster.

Special telescopic cable anti -seismic support of utility tunnel

The utility model relates to a special water supply and drainage pipeline anti -seismic support of utility tunnel, I shape circular arc spacing collar and base including butt joint from top to bottom,I shape circular arc spacing collar is the I shape semicircle tubular construction of upwards hunch -up, the base is recessed U -shaped metal crate structure, the left and right sides of I shape circular arc spacing collar and base all is provided with the bolt hole connection board, passes through the bolt fastening to the carried forward about the connecting plate. The utility model discloses can restrict the displacement that water supply and drainage pipeline produced in vibrating process, the antidetonation damping rubber pad that sets up respectively on base and the I shape circular arcspacing collar can avoid that water supply and drainage pipeline takes place deformation that whole bending deformation and water hammer brought to water feeding pipe under the effect of earthquake shear wave, damaging influence such as break, reaches shock -resistant function.
