Detailed Description

The utility model will be further described with reference to the drawings and embodiments.

Referring to fig. 1, fig. 2 and fig. 3 in combination, fig. 1 is a schematic structural diagram of a preferred embodiment of an overhead drainage pipeline pier suitable for water flushing in mountainous areas according to the present utility model; FIG. 2 is a schematic top cross-sectional view of the structure shown in FIG. 1; fig. 3 is a schematic cross-sectional structure of the foundation mat 1, the base plate 2 and the buttresses 3 shown in fig. 1. Overhead drainage pipeline buttress suitable for mountain area rivers wash includes: the foundation mat 1, fixed mounting has bottom plate 2 on the foundation mat 1, the top fixed mounting of bottom plate 2 has buttress 3, the drain pipe mounting hole has been seted up on the buttress 3, be equipped with overhead well 4 on the buttress 3, foundation mat 1 with bottom plate 2 all is located underground, the bottom of buttress 3 is located underground.

The bottom plate 2, the buttress 3 and the overhead well 4 are all reinforced concrete, the reinforced concrete is cement C30, and the steel bars are HPB300 grade steel bars and HPB400 grade steel bars.

The foundation mat 1 is plain concrete, the cement model of the concrete is C20, the thickness of the foundation mat 1 is 100mm, and the edge of the foundation mat 1 exceeds the edge of the bottom plate 2 by 100mm.

A drain pipe is arranged in the drain pipe mounting hole, and two layers of felt isolating layers are wrapped on the outer side of the junction of the drain pipe and the buttress 3; a10 mm gap is reserved between the outer wall of the drainage pipeline and the inner wall of the drainage pipe mounting hole, and asphalt hemp threads are arranged in the gap.

The buttress foundation is arranged on an old soil layer or a stratum with a certain bearing capacity, and the characteristic value of the bearing capacity of the foundation is not less than 130Kpa. If the requirement is not met, the foundation layer is dug more than 1m, and graded sand is adopted to clamp broken stone for filling and compacting treatment. The layered compaction thickness is 250mm, the compaction coefficient is more than or equal to 0.97, and the characteristic value of the bearing capacity of the treated foundation is not less than 130Kpa.

The compaction coefficient is determined by adopting a compaction test to control the maximum dry density of soil; the graded sand is clamped with broken stone to replace a filling layer, and the construction quality is checked by adopting a dynamic sounding test; the characteristic value of the bearing capacity of the foundation is determined by adopting a flat plate load test. And retesting the compactness and bearing capacity characteristic values after the foundation treatment is finished, and performing next construction after the design requirement is met.
