At present, Rizhao City has gradually entered the main flood season. In order to timely respond to emergencies in the flood season and effectively prevent and quickly dispose of public opinion, the Shugang Port toll station at Sugang Expressway adheres to the principle of “prevention-oriented, rapid response, full emergency rescue, and ensuring unimpeded accessâ€. Take measures to ensure safe and smooth roads during the flood season.
By-pass assembly has two positions; by-pass and close. It is in by-pass position during trip operation, and circulates mud fluid in the drill string into the annular space by-passing the idle motor, so that no mud may spray out onto the platform during the trip operation. When mud flow rate and pressure reach the setting value, the valve stem moves down and closes the valve. Meanwhile, mud stream flows through the motor, and converts the pressure energy into mechanical energy. As mud flow rate is too low, or mud pump stops, and as the pressure produced is not enough to overcome the spring force and the static friction force, the spring presses the stem upward, and by-pass is in open position. In general, the cross-over subs are used in deep well, large angle well, horizontal well or when hollow rotor is selected.

A station set up a flood prevention and protection leading group and a flood prevention and rescue commando team, organized all station workers to hold special meetings, highlighted the work of “fighting against firefighting, heatstroke prevention, fire prevention, explosion prevention, and lightning protection†and “strengthen the awareness of red lines and promote Safe development "safety production awareness is instilled in the hearts of every employee. Be active in the first time when a dangerous situation occurs and make every effort to cope with the danger;
Secondly, step up patrol efforts and intensify inspections of toll stations, power distribution rooms, courtyard drainage ditches and other special facilities as well as toll collection facilities and equipment. Problems should be solved in a timely manner to ensure that possible flooding disasters can be dealt with in the best possible conditions.
The personnel of the three organizations paid close attention to the changes in the weather and encountered timely reports of thunderstorms, heavy rain, etc. in order to arrange early and prevent them early. In combination with the actual work, we will formulate an emergency plan for flood prevention and preservation, increase the rapid response and emergency response capacity of the toll collection personnel in case of danger, and control and reduce the adverse impact on the traffic caused by rainfall, etc., to ensure the safe and smooth flow of the toll station area in the flood season.
Fourth, strengthen safety education in the flood season, conduct emergency drills and education on protection knowledge for all personnel, improve staff emergency response capabilities, and enhance personal protection capabilities.
5. Strictly implement the 24-hour on-duty and leadership-leadership system to ensure smooth communications during the flood season; combine practical preparations for emergency materials such as shovels, woven bags, and sand to provide adequate logistical support for the occurrence of dangerous situations.
