Bridge Design and Construction
Multiple profiles, and even within each cable bridge alignment in the draw in profile, can solve the problem between. The second reason that caused the trouble was due to the characteristics of foreign projects. The project general contractor by the U.S. Bechtel Corporation,[link widoczny dla zalogowanych], and designed in cooperation with our hospital. When we finish the construction drawings according to design intent Party, the Party subject to change according to their needs or require us to re-design. Construction plans to more than one version. The site of the U.S. construction management personnel to the construction unit has repeatedly issued CCN (Contract Change Notice that) change the design. Design changes, too, is hard to imagine the past,[link widoczny dla zalogowanych], domestic engineering. Repeatedly revised. Change at any time, from the plant's internal layout of the room's function, size, etc. are great changes. Completed the demolition of the construction unit. Chai Wan was built, there are many places up to several times as much. They joked that the project was \The actual situation of the construction site with the original design drawings vary greatly, in some places even beyond recognition, and even the room numbers are not on. A variety of channels, location of equipment have also changed. Problem, of course, is inevitable. This requires us to adapt to the characteristics of the design work, subject to the owners needs, on-site to solve the problem. In the dedication to customer service, spirit of being responsible for design, I worked tirelessly, running all over the site to learn more problems with the live site, drew a lot status map. Control a number of related drawings and CCN, find out the problem in context. Re-construction of design sketches, the construction unit construction as soon as possible, so that the smooth construction is injured. Later, I explained to the Bechtel problems surrounding the clearing. Description not responsible for the Institute. They expressed their understanding of, and the construction of hospital management highly praised. All distribution lines in accordance with design requirements and wear steel bridge laying. Not as a cable tray wiring for ceiling space return air channel and technology layers. As a return air channel in the ceiling space of the cable jacket to avoid odor inhalation air conditioning system. Cables, wires are required to wear steel pipe laying. However, in the specific construction. Steel cable through the large cross-section is relatively concentrated, spatial location is not enough, wearing the long distance and cable construction difficulties. I am in consultation with the United States after the omission of this part of the line moved to the ceiling return air channel space, replaced by cable tray routing, the problem is resolved. The project for the electronics factory. Phase 22000i, la2, 2l Phase II 5 (~ 000m2, were closed factory floor. To ensure product quality, do not allow outside air into the dust production plant. Heating, ventilation by more than one large centralized air conditioning units. Plant clouds within the ventilation ducts, width by up to 2.5m, occupying most of the upper space. with fire sprinkler pipe, etc., the ceiling is very little room left to a professional electric. especially the corridor ceiling, the main pipe-intensive professional ,[link widoczny dla zalogowanych], while the level of the laying of bridge hanger spacing 21'I1, booms and wind pipe collision, can not be installed. Finally, part of the bridge out of the corridor ceiling, large diameter duct to escape, to solve the installation of cable tray hangers . construction site, a number of unexpected problems occur frequently. As communication needs, the addition of many communications metal trough, the bridge channel is more crowded. To meet regulatory requirements, the original bridge made the appropriate compression, combined, will trunking communication squeezed. office floor did not go trough the ceiling space, simply set the communication layer of the metal trough in the dining room ceiling, punched the ground in the two-story, metal snake with Plastic Hose wall into the second floor of the communication lines installed within the 3 bridge construction steel cable tray straight section of more than 30m should be set 2O ~ 30nun the joints. over 22 buildings should be set expansion joints at expansion joints, the general disconnect 0.1m, there's no more than cantilever 11'I1. line segment change should be achieved through the elbow, can not achieve more than 90 to a change of direction. bridge at the bending radius of the transition should not be less than the bridge on the cable bending radius of the biggest of them. bridge between the straight line, between line segments and the elbow, applied as accessories for connection. such as wider boards, variable high board, direct plate, hinged panels. As for the cable distribution panel PDP motivated on the outlet way, the scene made the corresponding elbow, accessories, etc., the construction of the technical requirements are carried out by inspection, to ensure the overall quality of the bridge system. 4 cable laying cable in the bridge with nylon cassette within the fixed, fixed parts as follows: the level of laying, the cable both ends, turns and straight line at intervals of 5 ~ 10m; vertical installation, the cable top and at intervals of 15 ~ 2m. cable bridge in the first end of the cable and terminal , turns and straight line at intervals of 50m set number, type and start and end points, and so marked. bridge leads to the cable on the pipe wear protection,[link widoczny dla zalogowanych], steel pipe clamp firmly fixed on the bridge. orifices located mouth protection to prevent scratches Cables
