Roadbed anti-settling device considering roadbed structural strength
The invention relates to the technical field of road construction, and discloses a roadbed anti-settling device considering roadbed structural strength, which comprises a cement pavement, a roadbed layer is arranged at the bottom of the cement pavement, a first groove and a second groove are formed in the bottom of the cement pavement, and a through hole is formed in the side surface of the cementpavement; the through hole is communicated with the second groove, supporting rods are embedded in the bottom of the cement pavement, and the bottom ends of the supporting rods penetrate through theroadbed layer and extend into the bottom soil layer. According to the roadbed anti-settling device considering the roadbed structural strength, after the roadbed layer is settled, supporting can stillbe provided through the multiple supporting rods, cracking of the cement pavement after heavy pressure can be avoided, meanwhile, after the roadbed layer is settled, springs can push a base plate tomove downwards, then a valve handle is pulled through a first pull rope, and polystyrene foam can be injected into the bottom of the base plate; and after the polystyrene foam is expanded, the base plate is pushed upwards, so that a gap formed after sedimentation can be repaired in time.
本发明涉及道路建设技术领域，且公开了一种兼顾路基结构强度的路基防沉降装置，包括水泥路面，所述水泥路面底部设置路基层，所述水泥路面底部开设有第一凹槽和第二凹槽，所述水泥路面侧面开设有贯穿孔，所述贯穿孔与第二凹槽连通，所述水泥路面底部埋设有支撑杆，所述支撑杆底端贯穿路基层并延伸至底部土层内。该兼顾路基结构强度的路基防沉降装置，在路基层沉降后仍然可通过多个支撑杆提供支撑，可避免水泥路面受重压后崩裂，同时当路基层沉降后弹簧可推动基板下移，进而通过第一拉绳拉动阀门把手，可向基板底部注射发泡胶，发泡胶膨胀后将基板向上推动，有利于及时将沉降后形成的间隙修复。
