Problems solved by technology
[0002] In mountainous road sections with large precipitation and poor geological conditions, the rock layer or soil layer of the roadbed is easily washed and infiltrated by rainwater, which leads to the failure of the roadbed support structure. Big security risk
[0003] Under the load of large vehicles, it is easy to cause local collapse on the outside of the above-mentioned section of the road. Most of the existing reinforcement methods are to install reinforcement devices on the side of the easy-to-collapse section to rigidly support and fix both sides of the road.
Under the action of vehicle load, the side of the road section that is prone to collapse is squeezed and gradually expands outward, and the expanded road surface directly acts on the reinforcement device. In the long run, the connectors of the reinforcement device are loosened, and eventually lead to fatigue failure of the reinforcement device. problem, which directly affects the supporting performance of the reinforcement device

The invention discloses a supporting structure for preventing road collapse and belongs to the technical field of road construction. A supporting mechanism is formed by assembling a plurality of roadside supporting devices successively along a road extension direction. Each road side supporting device comprises a left supporting assembly, a right supporting assembly and a first connector connected between the left supporting assembly and the right supporting assembly. The left supporting assembly and the right supporting assembly are arranged on two sides of a rod and the left supporting assembly and the right supporting assembly are same in structure and are symmetrical about the center line of the rod. The right supporting assembly comprises an upper pressing plate, a lower pressing plate and a road side top plate slidably arranged between the upper pressing plate and the lower pressing plate. The device can support the side of an easily collapsed section elastically to prevent a fatigue failure problem of the supporting structure as the easily collapsed section is expanded outward gradually.
Description
technical field [0001] The invention belongs to the technical field of road construction, and in particular relates to a support structure for preventing road surface subsidence. Background technique [0002] In mountainous road sections with large precipitation and poor geological conditions, the rock layer or soil layer of the roadbed is easily washed and infiltrated by rainwater, which leads to the failure of the roadbed support structure. greater safety hazard. [0003] Under the load of large vehicles, it is easy to cause local collapse on the outside of the above-mentioned road section. Most of the existing reinforcement methods are to install reinforcement devices laterally on the easy-to-collapse road section to rigidly support and fix both sides of the road. Under the action of vehicle load, the side of the road section that is prone to collapse is squeezed and gradually expands outward, and the expanded road surface directly acts on the reinforcement device. In th...
