Roadbed improvement device

The utility model discloses a roadbed improvement device. The roadbed improvement device comprises a base, a first chemical liquid supply device and a drilling device, the first chemical liquid supply device can inject chemical liquid into a roadbed, and the material blocking piece can make roadbed soil drilled by the drill bit get close to the middle from the two sides of the drill bit, so that the roadbed soil falls into a ditch drilled by the drill bit, and soil burying is completed. According to the roadbed improvement device provided by the embodiment of the utility model, soil burying can be carried out while a chemical solution is injected into roadbed soil, so that the operation of a constructor on roadbed improvement is reduced, and the construction efficiency of roadbed improvement can be effectively improved. 本实用新型公开了一种路基改良装置。本实用新型的路基改良装置包括底座、第一化学液供给装置与钻地装置。第一化学液供给装置能够向路基注入化学液，挡料件能够使钻头钻开的路基土料自钻头两侧向中间靠拢，从而使路基土掉入钻头钻开的壕沟之中，完成土料掩埋。本实用新型实施例中的路基改良装置，能够在向路基土注入化学溶液的同时进行土料掩埋，减少了施工人员对路基改良需要进行的操作，可以有效地提升路基改良的
