Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a water-rich soft soil layer access road structure. Background Art

[0002] A construction access road refers to a temporary road built during the road and bridge construction process to ensure the smooth flow of the original road and facilitate traffic.

[0003] When constructing a temporary road on water-rich soft soil layers such as paddy fields, ponds and ditches, the compacted layer of the construction temporary road will gradually mix with the soft soil layer, which will cause potholes of varying sizes to appear on the temporary road. At the same time, the soft soil layer is mixed with rainwater to become silt, which will seep upward from the surface layer of the temporary road under the pressure of gravity of construction vehicles, affecting the movement of construction vehicles. The temporary road is the lifeline of construction. When there is a problem with the temporary road, it will seriously affect the normal progress of construction.

[0004] Based on this, the utility model designs a water-rich soft soil layer access road structure to solve the above problems. Utility Model Content

[0006] As a further solution of the utility model, a supporting net is laid below the compacted layer. The supporting net is made of PE rattan interlaced and woven, and is used to support the compacted layer from below to prevent the compacted layer from sinking locally.

During the rolling process, the green sand can be mixed downwards into the soft soil layer below, and the moisture in the soft soil layer is pressed out and absorbed by the green sand through the squeezing of the green sand, which can not only accelerate the hardening of the soft soil layer, but also the first layer can be compacted with the mixed soft soil layer through the characteristic of green sand absorbing water and compacting, so that the compacted layer has a certain bearing capacity to meet the requirements of traveling vehicles. At the same time, a supporting net is laid at the bottom of the compacted layer to prevent local sinking of the compacted layer, reduce the probability of subsequent pits and grooves, reduce the time of subsequent maintenance, and improve construction efficiency.

[0021] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0022] See also Figure 1-2The utility model provides a technical solution: a water-rich soft soil layer walkway structure, comprising a compacted layer 1, a drainage layer 2 and a surface layer 3. The compacted layer 1 is paved with green sand for forming compaction after being mixed with a soft soil layer. The drainage layer 2 is laid on the compacted layer 1 to drain the moisture in the soft soil layer and the compacted layer 1. The surface layer 3 is laid on the drainage layer to form a road surface. Green sand is used as the compacted layer 1. Through the water-absorbing and compacting characteristics of green sand, the green sand absorbs water and compacts after being mixed with the soft soil layer, thereby increasing the bearing capacity of the entire walkway and reducing the probability of forming potholes due to mixing of the material and the soft soil layer during the subsequent use of the walkway.

[0023] Specifically, a supporting net 4 is laid below the compacted layer 1. The supporting net 4 is made of PE rattan interlaced and woven, and is used to support the compacted layer 1 from below the compacted layer 1 to prevent the compacted layer 1 from sinking locally. First, the supporting net 4 is laid on the soft soil layer, and then green sand is laid on the supporting net, and finally the green sand is rolled. The green sand drives the supporting net 4 below to be mixed into the soft soil layer. In the process of mixing and squeezing the green sand and the soft soil layer, the moisture in the soft soil layer will be squeezed out and absorbed by the green sand, and the green sand will form compaction after absorbing water, thereby forming the compacted layer 1, so that the bearing performance of the compacted layer 1 is improved. In order to meet the construction requirements, the supporting net 4 below the compacted layer 1 can support the compacted layer 1 from bottom to top to prevent the compacted layer 1 from partially sinking during the subsequent driving of vehicles. Then, the drainage layer 2 and the surface layer 3 are laid on the top of the compacted layer 1. The compacted layer 1 is compacted with the soft soil layer to increase the bearing capacity of the compacted layer. At the same time, the probability of subsequent potholes is reduced, the time for subsequent maintenance is reduced, and the construction efficiency is improved. At the same time, the green sand can also play a role in drainage. When it rains, the accumulated water in the sidewalk can be quickly discharged to prevent the sidewalk from being flooded for a long time and causing the quality of the sidewalk to deteriorate.

[0024] Furthermore, the pore size of the supporting net 4 is 20-40 mm. When the compacted layer 1 and the supporting net 4 are rolled, the soft soil layer can pass through the supporting net 4 and be mixed with the compacted layer 1, thereby improving the compaction effect and effectively preventing local settlement of the compacted layer 1 during subsequent use.

[0025] like Figure 1 As shown, the surface layer 3 is paved with rough slag. The water-rich soft soil layer is generally located in mountainous areas, so the surface is paved with rough slag, which has low construction difficulty and low cost.

[0026] like Figure 1 As shown, the thickness of the compacted layer 1 is not less than 30 cm, which effectively improves the resistance of the later compacted layer 1 to the lower layer and meets the construction requirements.

[0027] like Figure 1As shown, the thickness of the surface layer 3 is not less than 50 cm, 20 cm of the bottom of the surface layer 3 is mixed with the drainage layer 2, and the surface layer 3 itself needs to retain 30 cm for heavy vehicles to travel, so the thickness of the surface layer 3 is not less than 50 cm.

[0028] like Figure 1 As shown, the compacted layer 1, the drainage layer 2 and the surface layer 3 constitute the main body of the walkway. The slopes on both sides of the main body of the walkway are cut at the same angle to prevent the wall surfaces on both sides of the main body of the walkway from collapsing, thereby ensuring the driving safety of the walkway.

[0029] like Figure 1 As shown, the top surface of the sidewalk body is inclined from the middle to both sides with a slope of 2.5% to 7%. When it rains, the slope of the top surface of the sidewalk body can quickly drain rainwater to both sides to prevent water accumulation on the top of the sidewalk.

[0030] like Figure 1 As shown, drainage ditches 5 are arranged on the left and right sides of the compacted layer 1, and the drainage ditches 5 are connected with the water system to ensure smooth drainage. The drainage ditches 5 are excavated from the surface of the soft soil layer, and are located on the left and right sides of the compacted layer 1 and are adjacent to the compacted layer 1. Rainwater flowing down from the main body of the walkway will converge into the drainage ditch 5 and be quickly discharged to avoid water damage. The size of the drainage ditch 5 is 50cm×50cm to ensure drainage efficiency.

[0031] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
