Description

Utility tunnel self-supporting pipeline support
Technical Field
The invention relates to the technical field of urban underground comprehensive pipe galleries, in particular to a self-bearing pipeline support for a comprehensive pipe gallery.
Background
With the needs of economic development and urban construction in China, urban underground comprehensive pipe galleries are playing a greater role in society. Power cables and communication cables are typically laid in racks as municipal lines that are preferably brought into the utility tunnel. The pipeline support is used in the utility tunnel with a large amount, and the later installation workload is large. The mounting quality of the bracket directly influences the normal use of pipelines in the pipeline laying operation and maintenance stages in the mounting stage.
To traditional pipeline support, the support stand is pre-buried in the structure wallboard or punches after the structure is accomplished and connect in structure wallboard surface usually at the structural construction stage, causes the local cross-section of wallboard to weaken, influences the structure atress performance, produces certain potential safety hazard, also can influence structure water-proof effects, reduces the durability of structure, causes reinforcing bar corrosion etc.. To high voltage power cable dead weight great, can cause the outer atress in utility tunnel wallboard plane. This adverse effect is often neglected in the design process. In addition, the pipeline bracket of the traditional pipeline bracket often has the problem of large installation error, thereby causing the problem of pipeline laying. On the other hand, receive great external load and structure temporarily and need consolidate the transformation under the condition at utility tunnel structure, traditional support can't provide the supporting role for utility tunnel structure body. Therefore, it is necessary to design a utility tunnel self-supporting pipeline support, makes the convenient high efficiency of installation, improves utility tunnel structure body atress performance to a certain extent.
Disclosure of Invention
The invention aims to provide a self-bearing pipeline bracket of a comprehensive pipe gallery, which is convenient to install and used for laying power cables and communication cables according to the installation conditions of the pipeline bracket of the urban underground comprehensive pipe gallery.
In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a utility tunnel is from bearing pipeline support, a serial communication port, the support includes the portal frame who is formed by stand, crossbeam, gusset, and the top and the crossbeam of stand link to each other, are connected with the gusset between stand upper portion and the crossbeam proximal end portion, along utility tunnel longitudinal arrangement a plurality of portal frame, a plurality of portal frame is by the vertical roof beam that links in upper portion, the vertical roof beam that links in lower part, alternately bracing longitudinal connection, forms wholly.
Furthermore, stand, crossbeam, angle brace are with bolted connection, form portal frame in utility tunnel cross section direction.
Further, the cable bracket arm is fixed on the upright post in advance.
Further, the portal frame is longitudinally arranged along the comprehensive pipe gallery and is arranged at intervals of 0.8-1.5 m.
Further, the cross inclined struts comprise four inclined struts arranged obliquely, the four inclined struts are fixed on the connecting plate through bolts, the X-shaped connecting plates are connected with the adjacent upright posts, and the cross inclined struts are connected with the upright posts of the adjacent portal frames longitudinally of the comprehensive pipe gallery.
Furthermore, the upright posts are supported on the lower longitudinal connecting beam, the lower longitudinal connecting beam is fixed on the bottom plate of the comprehensive pipe gallery through bolts, and the upper load is transmitted to the foundation.
Furthermore, the upper longitudinal connecting beam is longitudinally connected with the adjacent upright posts, and the setting height of the upper longitudinal connecting beam on the upright posts is flush with the connecting height of the angle brace on the upright posts.
Furthermore, all the components of the self-supporting bracket are made of steel subjected to corrosion prevention treatment.
Self-supporting pipeline support wholeness is good, all has better rigidity at utility tunnel cross section direction and vertically. In addition to bearing the dead weight of the support and the weight of the pipeline, the support can provide certain resistance for the comprehensive pipe gallery structure to resist external loads. The innovation points of the invention are as follows: the shortcoming that traditional pipeline support need be at the pre-buried component of structural construction stage or punch the installation after the structure is accomplished is solved, avoided pipeline support to the weakening of wallboard and external load of plane, eliminated the potential safety hazard of support mounting to utility tunnel structure. The self-bearing pipeline bracket of the comprehensive pipe rack is convenient to install, has good integrity along the cross section direction and the longitudinal direction of the comprehensive pipe rack, can provide certain resistance for the comprehensive pipe rack structure to resist external load, and has the effect of improving the stress performance of the comprehensive pipe rack structure body. The self-bearing cable support disclosed by the invention is wide in application, can be used for newly-built comprehensive pipe gallery projects, and can also play a good role in the reinforcement and transformation of existing projects.
