Simulation duct piece for synchronous grouting experiment

A simulation duct piece for a synchronous grouting experiment comprises a simulation duct piece body and a fixing seat, the simulation duct piece body is a hollow box body with the top face being an arc face and the bottom face being provided with holes, the simulation duct piece body is arranged above the fixing seat, partition plates arranged in a latticed mode are arranged in the simulation duct piece body, the interior of the simulation duct piece body is divided into multiple sets of containing grooves through the partition plates, and the containing grooves are formed in the bottom face of the simulation duct piece body. All the accommodating grooves are in contact with the opening in the bottom surface of the simulation duct piece, a plurality of groups of through holes are formed in the top surface of the simulation duct piece, and each group of accommodating grooves are communicated with the through holes; the containing groove is formed in the pipe piece and can be used for arranging a pressure test
