Problems solved by technology

[0003] At present, the existing roadbed is obtained by repeatedly ramming multiple layers of soil in the process of compaction. The roadbed obtained above, when the vehicles building the embankment transport building materials back and forth, the connection strength between the layers is relatively high. Poor, the tires of the vehicle will cause large indentations after being rolled, and the entire roadbed will appear potholes after long-term use, which will seriously affect the stability and safety of the vehicle when driving on the roadbed in the later stage. Therefore, it is necessary to propose a New technical solutions to solve the above problems

Embodiment 1

[0038] Embodiment 1: a kind of multi-layer compacted subgrade for building protection embankment, as figure 1 As shown, it includes a plain soil layer 1 and a multi-layer filler layer 2 compacted and stacked on the plain soil layer 1. The plain soil layer 1 is stacked with a compacted sandstone layer 3, a geotextile layer 4, Mixed soil layer 5, fiber grid layer 6, construction and domestic solid waste mixed layer 7, fiber grid layer 6, mixed soil layer 5, and sand and gravel layer 3 etc., thus the above-mentioned roadbed can be used as the foundation for building a protection embankment Vehicle used to transport construction materials.

[0039] In order to improve the connection strength between two adjacent layers, such as figure 1 As shown, a number of cylindrical connecting columns 8 are provided between two adjacent layers, and the upper and lower ends of the connecting columns 8 are respectively embedded in the two adjacent layers, and the connecting columns 8 are arrang...

Embodiment 2

[0054] Embodiment 2: A multi-layer compacted roadbed for building a protection dike. The difference from Embodiment 1 is that in order to reduce the chance of material such as soil being lost outwards, each layer of building and domestic solid waste mixed layer 7 A slope 9 is provided around the slope, and a concrete block 10 is provided at the slope 9. At this time, the existence of the concrete block 10 can play a position-limiting role, reducing the probability of loss of materials such as construction and domestic solid waste to the surroundings.

[0055] The construction method of the above-mentioned embodiment 2 includes the following steps: Step 1: clean up the construction site, excavate the foundation pit, and use a tamping machine to tamp the plain soil 3-4 times in the foundation pit, and then lay the fiber grid layer 6 on one side, Then use a tamping machine to tamp 2-3 times after filling the soil to obtain plain soil layer 1.

[0056] Step 2: Lay a sandstone lay...

Embodiment 3

[0061] Embodiment 3: A kind of multi-layer compacted subgrade for building a protection embankment, the difference from Embodiment 1 is: in order to reduce the chance of materials such as soil being lost outwards, in each layer of mixed soil layer 5 and building and living Slopes 9 are provided around the solid waste mixed layer 7, and concrete blocks 10 are provided at the slopes 9. At this time, the existence of the concrete block 10 can play a position-limiting role, reducing the probability of materials such as soil, construction and domestic solid waste being lost to the surroundings.

[0062] The construction method of the above-mentioned embodiment 2 includes the following steps: Step 1: clean up the construction site, excavate the foundation pit, and use a tamping machine to tamp the plain soil 3-4 times in the foundation pit, and then lay the fiber grid layer 6 on one side, Then use a tamping machine to tamp 2-3 times after filling the soil to obtain plain soil layer ...

Abstract

The invention discloses a multilayer compacted subgrade for building a protection embankment and a construction method thereof, and belongs to the technical field of building construction. The multilayer compacted subgrade for building the protection embankment is technically characterized by comprising a plain soil layer and a plurality of packing layers which are stacked in sequence and paved onthe plain soil layer, wherein a plurality of connecting columns are arranged between every two adjacent layers, and the connecting columns are internally provided with waste concrete fragments, wasteasphalt fragments, plastic bags, 108 adhesives, cement, sand and water; and the upper ends and the lower ends of the connecting columns are correspondingly embedded into every two adjacent layers, and the connecting columns are arranged in a staggered mode. According to the multilayer compacted subgrade, the connection firmness and the connection stability among the layers are improved, so that the damage speed of the subgrade is reduced, the service cycle of the subgrade is prolonged, and the stability and the safety of the vehicle in the driving process are further improved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and more specifically relates to a multi-layer compacted roadbed for building protection dikes and a construction method thereof. Background technique [0002] Ramming earth refers to the action of using heavy objects to press to remove voids in the soil, which makes the soil stronger. The general method of rammed earth is a kind of high-intensity manual labor that requires a lot of labor to ram the soil layer by layer with dry batting. [0003] At present, the existing roadbed is obtained by repeatedly ramming multiple layers of soil in the process of compaction. The roadbed obtained above, when the vehicles building the embankment transport building materials back and forth, the connection strength between the layers is relatively high. Poor, the tires of the vehicle will cause large indentations after being rolled, and the entire roadbed will appear potholes after long-term use,...
