Examples
Referring to fig. 1 to 5, the specific construction method includes the steps of:
step one, basic 8 processing:
after excavation, if the allowable stress of the substrate is less than 450kpa, substrate replacement or other measures should be performed.
If the bottom of the foundation 8 is virtual slag, the foundation must be compacted. The step type is adopted, and each step is divided into 10 m. The foundation 8 adopts C20 stone concrete, and the bottom is paved with C20 plain concrete. The base 8 is 500cm wide and 120cm thick.

If the intercepting ditch is arranged on the half slope, the drainage capacity cannot meet the requirement, and the construction of the intercepting ditch can be completed only after the filling of the abandoned slag yard is completed, so that the safety of the abandoned slag yard during the abandoned slag period cannot be ensured.
By constructing the waste residue field cover culvert with large catchment area and high earthing, the upstream water is successfully drained in the rainy season of 2017-2019, the safety of the waste residue field, downstream farmlands and river channels is ensured, and the construction period stagnation caused by the fact that the waste residue field is damaged by flushing is avoided.
The utility model discloses very effectively solve the large tracts of land problem of catchmenting of upper reaches gully, include 6 through setting up big section apron and draw the row, satisfy the drainage demand, reduced the rainy season and abandoned the potential safety hazard in sediment place, effectively alleviated the water pressure of abandoning the sediment place and bearing to the safety in low reaches farmland and river course has been ensured.
Enough space for discarding the slag is reserved, and the designed cover board culvert 6 can bear the pressure of high earth covering after being subjected to stress checking calculation, so that enough space is reserved for discarding the slag.
The slab culvert 6 is constructed in advance, the height of the abandoned soil is large in a narrow and long gully section, and if the drainage facility is not constructed or cannot function, the sidewalk and the abandoned slag are easily damaged by flushing, so that the slag-abandoning work cannot be carried out, the excavation and tunneling work of an extra-long tunnel is influenced, and the project is stopped. Therefore, the construction of the slab culvert 6 can avoid the stagnation of the engineering caused by unsmooth drainage in rainy seasons.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be considered by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention.
