The present application relates to rock foundation engineering technical field, disclose a kind of rock foundation groove excavation device, including splitting stick, water pump, bidirectional pump, slurry pump and rotary spray head, splitting shell in splitting stick is equipped with water bag, water pipe and slurry pipe, bidirectional pump is connected with water bag by intercommunication pipe to water injection to water bag in turn extrude splitting shell splitting rock, water pump is transported high pressure water to rotary spray head by water pipe to carry out drilling and cutting to rock, slurry pump is formed by slurry after high pressure water cutting and is extracted from construction area. Compared with prior art, the construction efficiency of the rock foundation groove excavation device is high, and the construction precision is good. The present application also provides a kind of rock foundation groove excavation method, also has the advantages of high construction efficiency, good construction effect.

The invention discloses a user information security management method and system based on a block chain, and electronic equipment, and relates to the technical field of information security. The method comprises the steps of block chain construction, information storage and information reading. The system is suitable for the method, and the electronic equipment is matched with the method. According to the application, the identification data segment and the information data segment of the user information data are split, then the unique personal identification identifier, namely the identity card number, is used as the identification code matched with the data, and the corresponding identification data segment is encrypted and then stored in the main node; and the information data segments are stored in the auxiliary nodes through the corresponding information association symbols, so that the information splitting is realized, the user information data processing process is enriched, the acquisition difficulty of the identification data ciphertext and the information data ciphertext is improved, the decryption difficulty of the identification data ciphertext and the information data ciphertext is improved, and the user experience is improved. And therefore, the security of the user information data in storage management and calling management is ensured.
