Construction structure for constructing road on soft soil foundation

Abstract

The invention relates to a construction structure for constructing a road on a soft soil foundation. The construction structure comprises a soft soil layer and a reinforcing column assembly partiallyinserted into the soft soil layer; the reinforcing column assembly comprises a plurality of reinforcing columns with hollow structures, and each reinforcing column is sequentially provided with a water inlet section, a reinforcing section, a drainage section and a connecting section from bottom to top; a first concrete layer is arranged at the top of the soft soil layer; a drainage layer is arranged at the top of the first concrete layer; a second concrete layer is arranged at the top of the drainage layer; each water inlet section is located in the soft soil layer; each reinforcing section islocated in the first concrete layer; each drainage section is located in the drainage layer; and each connecting section is positioned in the second concrete layer. By means of vertical drainage of the reinforcing columns, the soil body consolidation drainage distance can be shortened, the bearing capacity of the foundation is improved, the effect of reinforcing soft soil is achieved, the bearingcapacity and strength of the soft soil foundation can be effectively improved through the first concrete layer and the second concrete layer, and then the stability of the soft soil foundation is improved.

Description

technical field [0001] The present application relates to the field of road structures on soft soil foundations, in particular to a construction structure for building roads on soft soil foundations. Background technique [0002] The definition of soft soil foundation in my country's road industry standards refers to weak soil layers with low strength and high compression, most of which contain certain organic substances. Due to the low strength of soft soil and large amount of sinking, it often brings great harm to road engineering. If it is not handled properly, it will have a great impact on the construction and use of roads. [0003] When the paving process encounters local swampy areas or soft soil areas, if the rigid concrete is laid directly on the soft soil foundation, there will be a hollow area formed by the settlement of the soft soil foundation under the concrete road, which will easily lead to local collapse of the concrete road posed a threat to pedestrians an...

Due to the low strength of soft soil and large amount of sinking, it often brings great harm to road engineering. If it is not handled properly, it will have a great impact on the construction and use of roads.

[0003] When the paving process encounters local swampy areas or soft soil areas, if the rigid concrete is laid directly on the soft soil foundation, there will be a hollow area formed by the settlement of the soft soil foundation under the concrete road, which will easily lead to local collapse of the concrete road posed a threat to pedestrians and vehicles on the road
