Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road construction, in particular to a soft foundation highway reinforcing device and construction method. BACKGROUND

[0002] The roadbed refers to a strip structure as the foundation of the road surface according to the location and certain technical requirements of the route, and is the foundation of the railway and highway. Before the highway is built, the roadbed needs to be rammed to avoid the problem of subsidence of the roadbed, thereby improving the stability of the roadbed.

[0003] In the prior art, a rammer is usually used to ram the roadbed. However, when the roadbed is a soft foundation, in order to prevent the ground from sinking and cracking after filling, causing the structure to be unstable and other accidents, the soft foundation needs to be treated to make the settlement stable, until the bearing capacity of the foundation can meet the design requirements, thereby improving the strength of the soft foundation. However, in the process of use, when the water on the road surface cannot be discharged in time, the water on the road surface will seep into the soft foundation, so that the soft foundation cannot stably support the completed road surface, thereby causing the problem of subsidence of the soft foundation and cracking of the road surface.
