1. Mark the three cables of ethylene 1 # incoming line from the 111 distribution cabinet of the main distribution substation along the cable bridge to the ethylene substation.1. The cable and cable reel shall not be damaged during transportation and loading.It is forbidden to push down the cable reel directly from the vehicle.2. When rolling the cable reel, it must follow the arrow on the cable reel or the winding direction of the cable.
6. The maximum traction strength of the cable shall not exceed 70N/m ㎡.The speed should not exceed 15m/min.7. The minimum bending radius of the cable shall not be less than 15D (D is the cable diameter).8. The cables laid horizontally shall be fixed every 5~10m at both ends of the cable and at both ends of the turn and cable joint when there is a requirement for cable spacing.9. After cable laying, remove sundries in time.10. The cable shall be inspected before the production of cable terminal, and the cable insulation is in good condition;No dampness;Water shall not enter the cable.11.

In the bridge structure, the bearing is the connection point of the upper and lower structures of the bridge. Its role is to transfer the load of the upper structure to the bridge pier and abutment smoothly and safely, while ensuring the free deformation of the upper structure under the action of load, temperature change, concrete shrinkage and creep and other factors, so as to make the actual stress of the structure conform to the calculation diagram, and protect the beam endThe pier cap is not damaged.In some beam bridges built in the early stage, there is a widespread problem of bearing aging, some rubber bearings are aging, some steel plate bearings are rusted and ineffective, and some simple supported bridges with small spans have no bearings, which causes a series of problems under the current load of large tonnage and large traffic volume,The support needs to be replaced or added urgently.At the same time, due to the needs of transportation, the construction of bearing replacement is required to be higher without interruption or to shorten the interruption time as far as possible, so the overall replacement of bridge bearing is extremely important.
The drainage gate valves of the five pumps in the pump room of No. 7 Middle School have been used for many years. Due to the serious corrosion of the oil cylinder gate valves, the water leakage is serious after the valves are closed, which seriously affects the drainage capacity. In order to ensure that the safety workshop and the motor department decide to replace the drainage gate valves and overhaul the pumps, a construction scheme is specially formulated to ensure the smooth construction.

According to the actual situation of the site, the receiving and launching cylinders of Changsha Station and Zhuzhou Station can no longer meet the needs of the site due to the increase of the actual working pressure;Therefore, the receiver and launcher of Changsha Station with the level of PN64 shall be removed and replaced with the receiver and launcher with the pressure level of PN100;Remove and replace the PN40 receiver of Zhuzhou Station with a PN64 receiver.
For concrete-filled steel tube arch bridges with suspender problems, replacing the suspender is the most effective way to eliminate hidden dangers.At present, the replacement of suspenders is still in the trial stage. There is still a lack of clear specifications and unified standards for whether the bridge needs to replace suspenders, which affects the service life of arch bridges and makes it difficult to give full play to its due economic and social benefits.
During the cable laying and removal of this project, the ethylene plant was in normal production, and six cables of two incoming lines were in live operation, and the new and old cables were the same bridge, which brought great difficulties to the construction.
