An educational construction kit and methods are disclosed. The kit may have a plurality of blocks, each one of the blocks having an integral block data flow, a power exchange, and a structural connector side. Each one of the plurality of blocks may have (a) reprogrammable software to enable end-users to reprogram a unique and a specific behavior of each of the plurality of blocks; and (b) an embedded electronic device with a microcontroller that processes the reprogrammable software to instruct the respective block to perform the unique and the specific behavior. Interconnection of two or more blocks of the plurality of blocks may form a distributed communication network. At least one block of the plurality of blocks may include an additional component to allow the block to perform a different behavior from at least one other block.

This invention discloses a model test device and method for curtain grouting and excavation of tunnels in high-temperature, water-rich and weak strata, comprising weak strata simulation system, working condition simulation system, curtain grouting system, and monitoring and data acquisition system. The weak strata simulation system is the main box used to fill the soft soil. The working condition simulation system includes a high geothermal simulation system, a water pressure simulation system with stepwise loading of water pressure and volume, and a three-dimensional confining pressure simulation system with stepwise controllable loading of confining pressure. The invention can realize the whole test process simulation of grouting reinforcement and excavation of tunnels in weak strata effectively under the action of confining pressure and geothermal heat, and it has a positive reference effect on actual soft stratum tunnel curtain grouting and safe excavation.
