The surface of the clay edging body 2 is fixedly connected with a slope filling body 3;
further, the slope filling body 3 is made of coarse materials such as mountain-climbing stone slag, and the like.
Further, during construction of the carbonaceous mudstone subgrade matrix 1, the following steps are adopted:
measuring and paying off, namely measuring and lofting the central line and side lines of the roadbed according to the practically provided line parameters and the wire network, wherein each 20m of straight line segments and large-radius curve segments form a section pile, and each 10m of small-radius curve segments form a section pile. Two control piles are further arranged outside the construction area to provide a basis for recovery, a section control pile is additionally arranged on two sides of the structure to prevent the center line pile and the side line piles from being damaged, the basis for recovery can be provided, and meanwhile, a cement mileage pile with the height of 15cm multiplied by 15cm and 1m is arranged on each 50m of the side of the roadbed, and pile numbers are marked for inspection during construction.
And step two, surface soil is removed, before the roadbed is filled and constructed, firstly, the surface must be cleaned, trees in the roadbed range are all cut down by adopting manpower strictly according to the instructions of drawing and supervision engineers, and vegetation outside the roadbed range is protected as much as possible. Cleaning tree piers, tree roots, weeds, shrubs and the like on the original ground in the road base filling range by using a bulldozer and an excavator;
the surface soil is removed by adopting a strip cultivation layer outside method for construction, namely stripping and transporting according to the strip from inside to outside. The surface soil is required to be concentrated and piled up after being removed, and the surface soil for later greening does not contain garbage, hard clay or gravel with the diameter of more than 5cm as much as possible;
the surface soil removal depth must meet the design requirement, the design is not lower than 30cm, and the boundary line is filled by lofting again after surface soil removal. The surface soil stripped by the surface cleaning is a precious banking resource for later greening, and the surface soil is intensively piled in a temporary waste soil field of the surface soil of the project and is used for later greening. The surface soil stacking adopts a woven bag for bagging and stacking the side slope locking feet, and a green net is covered on the surface.
And thirdly, rolling before filling the substrate by adopting a road roller after cleaning the surface, detecting the compactness of the substrate after rolling, wherein the compactness of the substrate is not less than 90%, the compaction thickness is 15cm, if the compactness cannot meet the requirement, continuing rolling, and detecting the compactness once every time of rolling until the compactness is not less than 90%.
Step four, step excavation, namely when the original ground transverse slope is delayed to be 1:5, directly filling roadbed on the natural foundation after surface soil is removed. When the ground transverse slope is 1:5-1:2.5, the original ground excavation width is 3m, and the inward inclination gradient is 4% of the step. When the covering layer on the bedrock is thinner, the covering layer is removed firstly and then the steps are dug; when the cover layer is thicker and stable, it can be preserved.

And step six, transporting the filler, loading by using an excavator or a loader, transporting to a construction site from a scheduled transportation route by using a dump truck, and pouring the dumped filler into the arranged square grids to be piled up in a concentrated manner by command of a special person so as to ensure that the loose paving thickness of the lower embankment is not more than 50cm after the bulldozer is leveled.
And step seven, paving the filler, namely paving the filler by using a bulldozer to be smooth after the filler is piled up according to the square grid. When the bulldozer paves, the paving layer thickness is slightly smaller than the paving thickness, so that later leveling and partial fine material supplementing are facilitated, and individual stone blocks with oversized particle sizes are selected by manually matching with the loader;
checking loose pavement thickness: measuring the elevation of the top of the filling layer by using a level gauge every 40m of one section and every 3-5 points of the section, detecting whether the loose pavement thickness meets the requirement according to the elevation difference between the elevation of the top of the filling layer and the corresponding point of the lower filling layer, and pushing the loose pavement to the section to be filled or the outside of a transportation field by using a bulldozer or a loader in a range where the loose pavement is larger than the requirement.
Step eight, rolling, wherein the rolling forward road roller driver carries out bottom crossing content comprising: rolling mileage range, compaction pass number, mechanical walking speed, compaction combination sequence, longitudinal and transverse overlapping length during compaction and related safety precautions.
Before rolling, detecting whether the water content of the filler meets the specification requirement by adopting an alcohol combustion method, and generally controlling the water content to be within +/-2% of the optimal water content, wherein if the water content is higher than the specification requirement, the sun-drying is carried out; and when the water content is low, water sprinkling and supplementing are carried out.
After filling the filler, firstly adopting a road roller to roll the filling surface approximately flat, then adopting a vibratory roller to roll, keeping the two sides and the middle, standing and vibrating, slowing and then quickly, and sequentially rolling from the road edge to the road center and from the road center to the two sides of the running route of the straight-line road roller so as to form a road arch; when the curve is provided with an ultrahigh gradient, rolling from the lower side to the higher side so as to form a unidirectional ultrahigh gradient. The rolling speed is controlled to be 2-4 Km/h, the joint parts are mutually overlapped and compacted, the longitudinal overlap length is not less than 2m, the overlapped compaction of the turbines along the longitudinal rows and the rows of the line is not less than 1/3 wheel width, and the overlapped compaction of the joints of the transverse same layers is not less than 1m; the staggered joint of the upper layer and the lower layer is not less than 3m.
Rolling compaction indexes: the compactness meets the requirements.
Further, when the carbonaceous mudstone roadbed is filled, the construction of the clay edging body 2 and the slope filling body 3 is synchronously carried out, the clay edging is carried out by 200cm, the ultra-wide filling of 50cm is carried out on the two sides of the embankment, the compactness of the edge part of the roadbed is ensured, and the slope cutting treatment is carried out after the rolling is finished.
