A method, device and system for requesting and transmitting a service are provided, which belong to the communications field. The method includes: a bidirectional device of the head end receives a service request transmitted by a terminal device and obtains the corresponding service (101); the bidirectional device of the head end judges whether the service can be distributed by an unidirectional device of the head end (102); if yes, the bidirectional device of the head end routes the service to the unidirectional device of the head end, so that the unidirectional device of the head end distributes the service to the terminal device (103); otherwise, the bidirectional device of the head end distributes the service to the terminal device (104). By dispensing with the process of a service server in the prior art in the present invention, the bidirectional device of the head end obtains the service from the service server and judges whether the service data is distributed by the unidirectional device of the head end or is interacted through a bidirectional network (such as Internet Protocol (IP) network), so as to distribute, through utilizing high-bandwidth unidirectional network, heavy traffic IP broadcast and multicast data which originally need to be distributed by the bidirectional network, and therefore the bandwidth pressure on the bidirectional network is mitigated.

The invention provides a construction method of a tunnel center inspection well lid adaptive to heavy traffic rolling. The construction method of the tunnel center inspection well lid adaptive to theheavy traffic rolling includes following steps: step 1, prefabricating a lid plate; step 2, setting the midpoint of an inspection well as the center, and chiseling a lid plate groove from the center to the periphery of the inspection well; step 3, using mortar for levelling the bottom of the lid plate groove, and burying a metal bearing piece before the motor solidifies; step 4, placing a rubber cushion on the metal bearing piece, placing the lid plate prefabricated in the step 1 in the lid plate groove chiseled in the step 2, and contacting the surface of the rubber cushion with the bottom surface of the lid plate; step 5, filling an interval between the lid plate and a pavement panel with a material layer. According to the construction method of the tunnel center inspection well lid adaptive to the heavy traffic rolling, the lid plate is underlaid with groove steel, and therefore bearing capability of the lid plate is improved, and the rubber cushion is mounted below the lid plate, and therefore the lid plate is adaptive to vehicle dynamic load. The construction method of the tunnel center inspection well lid adaptive to the heavy traffic rolling buries the metal bearing piece under the circumstance that a mortar levelling layer does not solidify, enables the mortar levelling layer to fully wrap the metal bearing piece, and enables the mortar levelling layer and the metal bearing piece to generate joint bearing capacity.
