The invention discloses a rockfall prevention structure for a tunnel portal. The rockfall prevention structure for the tunnel portal aims to substantially reduce the amount of moving rocks at the tunnel portal, lower the construction cost of a rockfall prevention project and reduce the construction difficulty. The rockfall prevention structure for the tunnel portal comprises a tunnel portal structure and a rockfall happening area located on a slope face above the tunnel portal structure. A falling rock induction groove is formed in the portion, between the tunnel portal structure and the rockfall happening area, of the slope face. The falling rock induction groove is provided with an arc top segment, a left side segment and a right side segment, wherein the arc top segment is close to the rockfall happening area, and the left side segment and the right side segment extend downwards along the original slope face to the portions outside the tunnel portal structure and the line.

The invention discloses a service processing method, a terminal and a server, belonging to the technical field of internets. The terminal and the server authenticate each other in service processing,wherein the authentication process depends on not only a stored secret key or an encryption algorithm but also terminal session data, a terminal request identifier and a secret key, after authentication succeeds, the service is processed. The terminal session data and the terminal request identifier are generated by the terminal in communication with the server, therefore, even if other terminalscan acquire secrete keys stored by the terminal and the server, the terminals cannot acquire the terminal session data and the terminal request identifier, volume is prevented from increasing, the processing pressure of the server is lowered, the server is safer, and the service has better performance.

The invention aims to provide a ship dual-fuel engine fuel supply system capable of preventing a natural gas change loss. The ship dual-fuel engine fuel supply system comprises a natural gas tank, a mixer, a combustion chamber and an air main pipe; an intake main pipe is arranged in an intake valve of the combustion chamber; an exhaust passage is formed in an exhaust door of the combustion chamber; a diesel nozzle is mounted in the top of the combustion chamber; the natural gas tank is communicated with an inlet of a natural gas channel; an outlet of the natural gas channel is communicated with the mixer; the mixer is communicated with the intake main pipe through a mixed gas intake passage; the tail end of the air main pipe is divided into a first branch pipe and a second branch pipe; the first branch pipe is communicated with the mixer; and the second branch pipe is communicated with the intake main pipe. The ship dual-fuel engine fuel supply system prevents mixed gas from being directly fed into air in the gas change process, so that the fuel waste and the environmental damage are prevented.

The invention discloses a logistics transportation automatic sorting line. The bottom faces of the connecting positions of a first conveying plate and a second conveying plate of a conveying device of the logistics transportation automatic sorting line are hinged through a hinge, and the two conveying plates are connected through a telescopic pipe.
