Problems solved by technology
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] In view of the above-mentioned related technologies, the inventor believes that after the road is built on the soft soil foundation, the soft soil foundation is prone to settlement, making the road prone to collapse

Embodiment Construction
[0040] The following is attached Figure 1-4 The application is described in further detail.
[0041] The embodiment of the present application discloses a construction method for constructing a road on a soft ground. refer to figure 1 , the construction method for constructing roads on soft ground includes the following steps:
[0042]Step 1: excavation of foundation pit 2. Organize personnel to survey and measure the soil quality of foundation 1, and draw a section drawing and construction design drawing. The construction personnel excavate foundation 1 according to the section drawing and construction design drawing, and excavate a depth of about After the foundation pit 2 of 2 meters is excavated, the bottom of the foundation pit 2 and the side walls of the foundation pit 2 are leveled to keep the bottom of the foundation pit 2 and the side walls of the foundation pit 2 flat, and then the soil at the bottom of the foundation pit 2 is leveled. Do compaction.

The invention relates to a construction method for constructing a road on a soft soil foundation. The construction method comprises the following steps that: firstly, the foundation is excavated, a foundation pit is formed through excavation, redundant sundries in the foundation pit are removed, it is ensured that the bottom and the side wall of the foundation pit are flat, and soil in the foundation pit is tamped; secondly, a water permeable cushion layer is laid at the bottom of the foundation pit; thirdly, a plurality of reinforcing cylinders are laid on the water permeable cushion layer, the foundation pit is filled with a backfill soil layer, the water permeable cushion layer is embedded in the backfill soil layer, and then the backfill soil layer is tamped; fourthly, a shaping frame is mounted in the foundation pit, the shaping frame is located at the tops of the reinforcing cylinders, the shaping frame and the reinforcing cylinders are fixed through connecting pieces, a plurality of embedded assemblies are mounted on the inner side face of the shaping frame, then concrete is poured into the shaping frame, and a concrete layer is formed after the concrete is solidified; and fifthly, the concrete layer is cured, and after curing is completed, a road is laid on the concrete layer. The stability of the soft soil foundation can be improved.
Description
technical field [0001] The application relates to the field of road construction on soft soil foundations, in particular to a construction method for building roads on soft soil foundations. Background technique [0002] With the rapid development of the economy, the construction of roads is very important. The subgrade is not only the main body of the route, but also the foundation of the road surface, and bears the vehicle load together with the road surface. 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] With regard to the related technologies mentioned above, the inventor believes that after the road is bui...
