Embodiment

[0040] refer to Figure 1-Figure 5 As shown, the specific construction method includes the following steps:

[0041] Step 1, basic 8 processing:

[0042] After excavation, if the base allowable stress is less than 450kpa, base replacement or other measures should be taken.

[0043] If the bottom of foundation 8 is virtual slag, it must be compacted. Use steps, with a step every 10m. The foundation 8 is made of C20 rubble concrete, and the bottom is made of C20 plain concrete. Foundation 8 is 500cm wide and 120cm thick. Its vertical slope reaches 15.3%, and a slag retaining dam is constructed at the upstream end of the cover culvert 6, using C20 rubble concrete. The slag retaining dam is 44 meters long and 5 meters high, and adopts a trapezoidal structure. Mainly due to the large flow of water at the uppermost end of the cover culvert 6, in order to avoid the danger caused by a large amount of incoming water directly pouring into the spoil yard, a large-volume slag retaini...

Abstract

The invention discloses a cover plate culvert structure of a high-earthing spoil disposal site and a construction method of the cover plate culvert structure. The cover plate culvert structure of thehigh-earthing spoil disposal site comprises a foundation bottom layer arranged in a stepped mode and a plurality of U-shaped unit culvert structures with downward openings. Each U-shaped unit culvertstructure comprises a wall body and a cover plate, connecting steel bars are arranged between the lower portion of the wall body and the foundation, a cover plate groove is reserved in the upper portion of the wall body, settlement joints are reserved between the adjacent wall bodies, filling materials are arranged in the settlement joints, and hoisting steel bars are arranged on the upper portions of the cover plates. The cover plate culvert structure is high in operability, simple and reliable. The drainage requirement and the enough bearing capacity are fully met through the large section,high soil covering is achieved, the requirement for the waste slag space is met, through implementation of the technology, upstream large-flow incoming water is successfully guided and drained to thedownstream, and safety and reliability of the spoil disposal site are guaranteed.

Description

technical field [0001] The invention relates to the technical field of construction of a spoil ground, in particular to a cover slab and culvert structure of a spoil ground with high covering soil and a construction method thereof. Background technique [0002] The spoil yard, that is, the slag yard, the upper catchment area of ​​the slag yard should not be too large, and should be located in the warehouse as much as possible. The selection and dumping principles of the waste dump should generally be followed: the catchment area of ​​the upstream of the dump should not be too large, the topography of the dump should be small and large, and the storage capacity should be large; Above the slag field, there should be no catchment depressions and gullies at both ends of the slag field; the geological structure of the slag field is stable and the soil is hard; if there is polluted slag, anti-leakage should also be considered. [0003] The waste slag site built by our company has...
