The utility model relates to the technical field of parking space locks, in particular to a buried parking space lock which comprises a box body, a turning plate and a driving device. The box body is provided with a containing groove with an upward opening, one side of the turning plate is hinged into the containing groove, and the driving device is arranged in the containing groove. The driving device comprises a lead screw driving assembly, a driving connecting rod and an auxiliary tension spring, the lead screw driving assembly is arranged in the containing groove in the second horizontal direction, the two ends of the driving connecting rod are connected with the lead screw driving assembly and the turning plate correspondingly, and the two ends of the auxiliary tension spring are connected with the turning plate and the box body correspondingly; the first horizontal direction is perpendicular to the second horizontal direction; the lead screw driving device is perpendicular to the rotating direction of the turning plate, and meanwhile, the auxiliary tension spring has the counterweight effect on the turning plate, so that the requirements for the strength of the lead screw and the power consumption of the motor are reduced, the size of the driving device is reduced, and the problems that in the prior art, a parking lock driving assembly is large in size and inconvenient to use are solved. And the parking space lock is large in overall size and inconvenient to install.

The utility model discloses a light high -strength prefabricated assembled ribbed slab type abutment, include: bottom support platform, ribbed slab is provided with two groups, two groups of ribbed slab symmetry fixed connection in the top surface of bottom support platform, platform cap shell is fixed in the top of ribbed slab, the top surface fixed connection of ribbed slab has I -steel connecting piece, and I -steel connecting piece inserts into platform cap shell, and fixedly connected with connecting reinforcing steel bar, back wall, back wall side two ends symmetry fixed connection has ear wall, back wall and ear wall integrated, and the outside of platform cap shell is fixed between back wall, wherein, after I -steel connecting piece inserts into platform cap shell, uses concrete pouring fixed. The utility model each component can be prefabricated in advance in factory. In construction site, only need to carry out simple assembling operation, has greatly shortened construction period. Compared with traditional on -the -spot pouring construction mode, need not to wait for concrete maintenance to reach design strength, has saved a lot of time.
